Description

Multi-ratchet type mute clutch

Technical Field

The invention relates to a multi-ratchet type mute clutch which is mainly used in the technical field of transmission.

Background

In most cases, the power output characteristics provided by the power source of the machine do not match the power input characteristics required by the implement, and therefore, a special transmission system is often required to drive the implement of the machine after the power of the power source is subjected to speed change and/or differential transmission. In addition, because the actual working conditions are complex, in many cases, a transmission system often needs to be provided with a plurality of power transmission paths, namely a plurality of gears, so as to meet the requirements of the machine on various aspects such as dynamic property, economy and the like under various working conditions. In order to realize smooth switching of a transmission system between a plurality of gears and ensure that power between the gears does not interfere with each other, a special gear shifting device is generally required to be arranged.

The gear shifting device is generally arranged in a transmission system of the machine, or between a power source and an executing device of the machine, or between a driving part and a driven part of the machine, or between a moving part and a frame of the machine. The currently common shifting devices have: one-way clutches (or overrunning clutches), centrifugal clutches, hydraulic or motor-driven friction plate clutches, electromagnetic clutches, magnetic powder clutches, ratchet clutches, dog clutches, synchronizers, and the like. The ratchet clutch selectively realizes the transmission of various powers, motions, loads, rotating speeds and torques by utilizing the engagement and the disengagement of the pawls and the ratchet. The pawl and the ratchet wheel are in surface contact, so that the bearing capacity of the ratchet wheel clutch is high. And engagement and disengagement of the pawl and the ratchet is easily achieved by means of various operating mechanisms. However, the conventional ratchet clutch generally has one ratchet (if the half clutch on which the pawls are mounted is also considered as the ratchet, the conventional ratchet clutch generally has two ratchets), and when the pawls are engaged with and disengaged from a single ratchet, vibration, shock and noise are inevitably generated, resulting in low reliability of the ratchet clutch. And when the ratchet clutch is used as a one-way clutch or an overrunning clutch, the pawl continuously collides with the ratchet wheel when running in a separation state or an overrunning state to generate vibration and noise, so that the working environment of operators is influenced, and the reliability and the service life of the pawl and the ratchet wheel are obviously reduced. In addition, because the pawl and the outer diameter of the ratchet wheel are usually in a sliding contact state, the transmission efficiency of the ratchet wheel clutch is reduced, the application range of the ratchet wheel clutch is limited, and the requirement on the wear resistance of the pawl is high.

Therefore, the development of a silent ratchet clutch with low operation noise, high reliability and high transmission efficiency becomes a research direction with great potential in the current transmission technical field. Once these shortcomings of conventional ratchet clutches are overcome, the application range of ratchet clutches will be greatly expanded, and a new field of view is provided for the development of new transmission systems.

The invention also provides a plurality of centralized clutch devices, parking devices, novel differentials, braking systems, safety devices, novel transmission systems, novel modules and novel machines which are used in the transmission field and use the multi-ratchet type mute clutch MRC.

Compared with the prior art, the multi-ratchet type mute clutch MRC has the following advantages:

(1) the running noise is low, simple structure, reliability is high, transmission efficiency is high: because the multi-ratchet wheel type mute clutch MRC can be additionally provided with the roller wheel to the pawl, the pawl is contacted with the surface of the ratchet wheel through the roller wheel in an overrunning state, and the transmission efficiency and the reliability of the clutch in a one-way separation or overrunning state are greatly improved; when the ratchet wheel provided with the pawl has higher rotating speed, the pawl in a separation state or an overrunning clutch state can overcome the elastic force of the return spring under the action of centrifugal force so as to completely break away from the contact with the corresponding ratchet wheel; when the rotating speed of the ratchet wheel provided with the pawl is lower, the pawl restores to be in contact with the corresponding ratchet wheel under the action of the elastic force of the return spring, so that the transmission efficiency of the clutch is further improved, and meanwhile, the MRC can be used for the working condition with higher rotating speed; in addition, the multi-ratchet wheel type mute clutch MRC adopts the interaction of the plurality of ratchet wheels and the pawls, thereby not only preventing the pawl roller from bearing larger load and being damaged when the clutch transmits power, but also enabling the pawl roller to contact with the spliced cylindrical surface or plane of the plurality of ratchet wheels when the pawls are separated from the ratchet wheels, obviously reducing noise and greatly improving the reliability of the ratchet wheel clutch. Moreover, most parts of the multi-ratchet type mute clutch MRC are simple in structure and uncomplicated in manufacturing process; compared with a common ratchet clutch, the multi-ratchet mute clutch MRC can also be added with a buffer damping link, so that the vibration and impact generated in the power engaging and disengaging process are greatly reduced, the loading condition of each part is obviously improved, and the reliability of each part is greatly improved.

(2) Good controllability and low control difficulty: part of clutch devices of the multi-ratchet type mute clutch MRC have a self-clutch function according to actual working conditions, and other gear shifting devices are provided with special actuating devices to realize clutch operation, so that the whole gear shifting device is good in controllability; and the multi-ratchet type mute clutch MRC is provided with a special buffer damping device for reducing vibration and impact generated in the process of power connection or power separation, all functional modules of the multi-ratchet type mute clutch MRC are clearly divided into work and do their own work, the functional overlapping performance of all the modules is less, the requirements on the functions of the modules of a control system are lower, and therefore the development difficulty of the whole control system is lower.

(3) The modularization level is high, the commonality is good, scalability is strong: the multi-ratchet type mute clutch MRC is composed of different functional modules, different clutch modules are changed as long as the multi-ratchet type mute clutch MRC is assisted with different actuating device modules, buffer damping device modules and the like, the multi-ratchet type mute clutch MRC can almost replace all traditional gear shifting devices (one-way clutch, centrifugal clutch, friction plate type clutch, electromagnetic clutch, magnetic powder clutch, synchronizer and the like), and can be expanded to develop parking devices, safety protection devices (torque limiting, speed limiting and the like), braking devices (traditional braking devices, driving retarding devices, IBooster and the like), automobile front and rear axle transfer cases, inter-wheel anti-skid differentials, centralized synchronizers and the like based on the multi-ratchet type mute clutch MRC. In addition, a plurality of gear shifting functions of one transmission system can be integrated into one gear shifting device, so that a centralized clutch with a centralized clutch control function is realized, and a brand new view is opened up for the transformation of the conventional transmission system and the development of a novel transmission system.

(4) No power interruption of the gear shifting process: because the special buffer damping device can be selectively added, the vibration and the impact in the gear shifting clutch process are smaller, and therefore, the direct gear shifting can be realized under the condition of not cutting off the power, and the gear shifting function without power interruption can be selectively realized.

(5) The manufacturing cost is low: the multi-ratchet type mute clutch MRC has simple parts and simple structure, adopts modular structure design, has higher universality, lower gear shifting control difficulty and no power interruption in the gear shifting process, and has very wide application prospect. This makes it possible to mass-produce the parts and functional modules of the multi-ratchet type silent clutch MRC in a modular manner, thereby reducing the overall manufacturing cost.

Example 1

The multi-ratchet type mute clutch MRC includes a multi-ratchet clutch device MRM as shown in fig. 1 to 9. The multi-ratchet clutch device MRM is a radial one-way clutch mechanism 91, as shown in fig. 1 to 9, and includes: the first inner ring comprises a first inner ring 1, a first outer ring 3, a first pawl 6, a first return spring 10, a first outer ring left support 34, a first outer ring right support 35, a first outer ring rivet 53, a first auxiliary inner ring 11, a second auxiliary inner ring 12, a first auxiliary inner ring limit pin 61 and a first auxiliary inner ring limit pin roller 62. In the radial direction, the first outer ring 3 is arranged outside the first inner ring 1. In the radial direction, the first outer ring 3, the first pawl 6, the first return spring 10, the first outer ring left bracket 34, the first outer ring right bracket 35, the first outer ring rivet 53, the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary inner ring limit pin 61, and the first auxiliary inner ring limit pin roller 62 are all arranged coaxially with the first inner ring 1. In the axial direction, the first inner ring 1, the first outer ring 3, the first pawl 6, the first return spring 10, the first outer ring right bracket 35, the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary inner ring limit pin 61, and the first auxiliary inner ring limit pin roller 62 are all arranged on the right side of the first outer ring left bracket 34. The first inner ring 1, the first auxiliary inner ring 11, the second auxiliary inner ring 12, and the first outer ring 3 are configured with ratchet-like protrusions and grooves having at least a function of engaging and/or disengaging with the first pawls 6. As shown in fig. 1, the first pawls 6 are in an engaged state with the first inner race 1 at an initial position, in which the first inner race 1 is fixed in a reverse rotation direction (a reverse direction indicated by an arrow in fig. 1) and rotatable in a normal rotation direction (a direction indicated by an arrow in fig. 1) with respect to the first outer race 3. The first pawls 6 are in an engaged state with the first auxiliary inner race 11 at an initial position, at which the first auxiliary inner race 11 is fixed in a reverse rotation direction (a reverse direction indicated by an arrow in fig. 1) and rotatable in a normal rotation direction (a direction indicated by an arrow in fig. 1) with respect to the first outer race 3. The first pawls 6 are in an engaged state with the second auxiliary inner ring 12 at an initial position, in which the second auxiliary inner ring 12 is fixed in a reverse rotation direction (a reverse direction indicated by an arrow in fig. 1) and rotatable in a normal rotation direction (a direction indicated by an arrow in fig. 1) with respect to the first outer ring 3. The first pawl 6 is mounted on the first outer race 3, the first pawl 6 rotating with the first outer race 3. The first pawls 6 are rotatable with respect to the first outer race 3 within an angular range defined by the first outer-race left bracket 34 and the first outer-race right bracket 35. The first return spring 10 is mounted on the first outer race 3, the first return spring 10 rotating with the first outer race 3. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. As shown in fig. 2, when the first pawls 6 are in the disengaged state from the first inner race 1, the first inner race 1 is rotatable in both the normal rotation direction (the direction indicated by the arrow in fig. 1) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 1) with respect to the first outer race 3 within a certain angular range. As shown in fig. 6, by designing the contact angle between the first pawl 6 and the first inner race 1 in the engaged state, the first pawl 6 and the first inner race 1 can have a certain self-locking function or anti-gear-shift function in the engaged state: when the first pawl 6 is in an engaged state with the first inner race 1 by the first return spring 10, assuming that an equivalent acting force between the first pawl 6 and the first inner race 1 is F, μ is an equivalent coefficient of friction between the first pawl 6 and a contact surface of the first inner race 1, F is an equivalent frictional force between the first pawl 6 and the first inner race 1, FN is an equivalent normal acting force between the first pawl 6 and a contact surface of the first inner race 1, and θ is an angle between F and FN, within a defined load range, the first pawl 6 and the self-propelled first outer race 2 are not disengaged even when an engaging force F between the first pawl 6 and the first inner race 1 is large (or within a certain load range) by the engaging force F, the elastic force of the first return spring 4, and the frictional force F when θ < arctan (μ), so that the first pawl 6 and the first inner ring 1 have certain anti-gear-off capacity or self-locking capacity in the engagement state. In particular, when the engagement force F is inclined at an angle toward the inner diameter direction of the first inner race 1 with respect to the normal acting force FN, as shown in fig. 5, the first pawls 6 and the first inner race 1 have a strong anti-disengagement capability or self-locking capability in the engaged state. Similarly, as shown in fig. 6, by designing the contact angle between the first pawl 6 and the first inner ring 1 in the engaged state, the first pawl 6 and the first inner ring 1 can have a certain overload protection function in the engaged state: the first pawl 6 is in an engaged state with the first inner race 1 by the first return spring 10, and within a limited load range, when θ > arctan (μ), and when the engagement force F between the first pawl 6 and the first inner race 1 is large (or exceeds a certain load range), the first pawl 6 and the first outer race 2 are disengaged by itself by the engagement force F, the elastic force of the first return spring 4, and the frictional force F. In this case, the multi-ratchet silent clutch MRC can be used as a safety clutch to prevent a large load from occurring in the transmission system during power transmission. As shown in fig. 2, 8 and 9, by designing the specific structure and constraint support conditions of the first pawl 6, the first pawl 6 and the first inner race 1 can have a certain function of centrifugal contact separation in the separated state: when the rotating speed of the first outer ring 3 exceeds a certain range, because the first pawl 6 is designed with an eccentric structure or a hollow groove structure, and the difference between the centrifugal forces applied to the two parts of the first pawl 6 with the rotation axis PA as a boundary is large, the first pawl 6 overcomes the elastic force action of the first return spring 10 under the action of the large centrifugal force and further rotates for a certain angle relative to the rotation axis PA, so that the first pawl 6 is completely separated from the first inner ring 1, and the transmission efficiency and the reliability of the multi-ratchet type mute clutch MRC are further improved. When the rotation speed of the first outer race 3 is low, the first pawls 6 are brought back into contact with the first inner race 1 by the first return spring 10. As shown in fig. 5, when the first pawl 6 is engaged with the first inner race 1 under the action of the first return spring 10, if the first pawl 6 and the first inner race 1 have a certain self-locking function in the engaged state, the centrifugal force of the first pawl 6 due to the eccentric structure is not enough to overcome the self-locking function between the ratchet and the pawl in a certain rotation speed range, so that the multi-ratchet type silent clutch MRC can still operate reliably (maintain the engaged state and is not influenced by the rotation speed change) in a certain rotation speed range. When the pawl structure is configured, the multi-pawl type mute clutch MRC can be used in a condition with a high rotation speed. The first outer ring 3, the first outer ring left bracket 34 and the first outer ring right bracket 35 are fixedly connected through the first outer ring rivet 53. The specific structure of the first pawl 6 is shown in fig. 7 or 8, and includes: a first body pawl 106, a first pawl roller 107, a first pawl pin 108. The first pawl pin 108 is fixedly coupled to the first body pawl 106. The first pawl roller 107 is connected to the first pawl pin 108. The first pawl roller 107 is rotatable relative to the first pawl pin 108. The first pawl roller 107 can also be connected to the first pawl pin 108 by means of a slide bearing, a rolling bearing or a clearance bearing in order to further reduce the rotational resistance of the first pawl roller 107. The second auxiliary inner ring 12 is fixedly connected with the first inner ring 1 through the first auxiliary inner ring limit pin 61. The first auxiliary inner ring limit pin roller 62 is mounted on the first auxiliary inner ring limit pin 61, and the first auxiliary inner ring limit pin roller 62 can rotate relative to the first auxiliary inner ring limit pin 61. The first auxiliary inner ring limit pin 61 radially supports and positions the first auxiliary inner ring 11 through the first auxiliary inner ring limit pin roller 62. The first auxiliary inner ring limit pin 61 can also be connected with the first auxiliary inner ring limit pin roller 62 through a sliding bearing, a rolling bearing or a clearance bearing, so that the rolling resistance of the first auxiliary inner ring limit pin roller 62 can be further reduced, the positioning accuracy between the first auxiliary inner ring limit pin roller 62 and the first auxiliary inner ring limit pin 61 is improved, and the positioning accuracy of the first auxiliary inner ring 11 relative to the first inner ring 1 is further indirectly improved. Under the action of the first pawl 6, the first auxiliary inner ring 11 can rotate relative to the first inner ring 1 within the angle range limited by the first auxiliary inner ring limit pin 61. When the first outer race 3 is reversed with respect to the first inner race 1 (in the opposite direction indicated by the arrow in fig. 1), the second auxiliary inner race 12 is fixed in the rotational direction with respect to the first inner race 1; under the action of the first pawl 6, when the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to an angle limited by the first auxiliary inner ring limit pin 61 (as shown in fig. 2), the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are axially spliced to form a cylindrical surface, and the first pawl 6 is in contact with the spliced cylindrical surface through the first pawl roller 107, so that the vibration and noise of the multi-pawl type silent clutch MRC in an overrunning clutch state are greatly reduced, and the transmission efficiency is improved. As shown in fig. 2, when the first pawls 6 are in a disengaged state from the first inner ring 1, and when the first outer ring 3 is rotated in the normal direction (the direction indicated by the arrow in fig. 1) with respect to the first inner ring 1, the second auxiliary inner ring 12 is fixed in the rotational direction with respect to the first inner ring 1; under the action of the first pawl 6, the first auxiliary inner race 11 rotates relative to the first inner race 1 to an initial angular position (as shown in fig. 4), and at this time, the first pawl 6 is restored to the initial position under the action of the first return spring 10, that is, the first pawl 6 is engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12. As shown in fig. 4, in order to avoid that the first pawl roller 107 is stressed greatly when the first pawl 6 and the first inner ring 1 are in the engaged state, the corresponding groove tooth profile portions of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are correspondingly deepened, but the corresponding groove tooth profile portion of the first inner ring 1 is not deepened (when the first pawl 6 and the first inner ring 1 are in the engaged state and stressed greatly, the side surface of the first pawl 6 contacts the corresponding portion of the first inner ring 1), so that the first pawl roller 107 is ensured not to bear a large load even when the first pawl 6 and the first inner ring 1 are in the engaged state under severe working conditions. The outer diameter of the first auxiliary inner ring 11 is equal to the outer diameter of the second auxiliary inner ring 12, and the outer diameters of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are slightly larger than the outer diameter of the first inner ring 1. In this way, when the first pawls 6 are in the disengaged state with respect to the first inner race 1, the first pawls 6 are in contact with only the first auxiliary inner race 11 and the second auxiliary inner race 12, and the contact area between the pawls and the ratchet in the disengaged state is further reduced, thereby further improving the idling efficiency of the multi-ratchet type mute clutch MRC in the disengaged state. And even if the outer diameter sizes of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are reduced due to long-term operation (abrasion), the first pawls 6 are still ensured not to be contacted with the first inner ring 1 in a separated state, so that the engagement and separation performance of the pawls and the ratchet wheel is not influenced, and the reliability, the durability and the like of the whole clutch can be improved to a certain extent. Because the outer diameter profiles of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are the same, and the first auxiliary inner ring 11 and the second auxiliary inner ring 12 only serve the purposes of reducing vibration and noise and increasing transmission efficiency, and the strength requirements of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are not high, the first auxiliary inner ring 11 and the second auxiliary inner ring 12 can be manufactured in large batch by adopting light metal, nonmetal or composite materials according to actual working conditions, and thus the cost can be greatly saved. And the first auxiliary inner ring 11 and the second auxiliary inner ring 12 can be connected into a component by adding a bearing, or the inner ring and the outer ring of the bearing are respectively manufactured into the same tooth profile shapes as the first auxiliary inner ring 11 and the second auxiliary inner ring 12, so that the mass production, the manufacture and the assembly are more convenient, and the production cost is further reduced.

Example 2

As shown in fig. 10 to 12, an embodiment 2 of the multi-ratchet type mute clutch MRC is similar to that of the embodiment 1, except that the first auxiliary inner ring limit pin roller 62 is removed from the multi-ratchet type mute clutch MRC, and a first clutch positioning bearing 4, a first auxiliary inner ring positioning bearing 16 and a first clutch positioning snap ring 45 are added; the first inner ring 1 positions and supports the first outer ring 3 in the radial direction and/or the axial direction through the first clutch positioning bearing 4; the second auxiliary inner ring 12 radially positions and supports the first auxiliary inner ring 11 through the first auxiliary inner ring positioning bearing 16; the axial position of the first auxiliary inner ring positioning bearing 16 relative to the second auxiliary inner ring 12 is positioned or limited by the first clutch positioning snap ring 45.

In the radial direction, the first outer ring 3 is arranged outside the first middle ring 2, and the first inner ring 1 is arranged inside the first middle ring 2. In the radial direction, the first inner ring 1, the first outer ring 3, the first pawl 6, the third pawl 8, the first return spring 10, the third return spring 30, the first middle ring left bracket 24, the first middle ring right bracket 25, the first middle ring rivet 52, the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary inner ring limit pin 61, the first auxiliary inner ring positioning bearing 16, the first auxiliary outer ring 31, the second auxiliary outer ring 32, the first auxiliary outer ring limit pin 81, the first auxiliary outer ring positioning bearing 36, the first clutch positioning bearing 4, and the second clutch positioning bearing 5 are all arranged coaxially with the first middle ring 2. In the axial direction, the first inner ring 1, the first middle ring 2, the first outer ring 3, the first pawl 6, the third pawl 8, the first return spring 10, the third return spring 30, the first middle ring right support 25, the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary inner ring limit pin 61, the first auxiliary inner ring positioning bearing 16, the first auxiliary outer ring 31, the second auxiliary outer ring 32, the first auxiliary outer ring limit pin 81, the first auxiliary outer ring positioning bearing 36, the first clutch positioning bearing 4, and the second clutch positioning bearing 5 are all disposed on the right side of the first middle ring left support 24. The first inner ring 1, the first middle ring 2, the first outer ring 3, the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary outer ring 31, and the second auxiliary outer ring 32 are configured with ratchet-like protrusions and grooves, and the ratchet-like protrusions and grooves have at least a function of engaging with and/or disengaging from the first pawls 6 and the third pawls 8. As shown in fig. 14, the first pawls 6 are in an engaged state with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at an initial position, and at this time, the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 are rotatable in a reverse rotation direction (a reverse direction indicated by an arrow in fig. 14) and fixed in a normal rotation direction (a direction indicated by an arrow in fig. 14) with respect to the first middle race 2. As shown in fig. 14, the third pawls 8 are engaged with the first outer race 3, the first auxiliary outer race 31, and the second auxiliary outer race 32 at an initial position, and at this time, the first outer race 3, the first auxiliary outer race 31, and the second auxiliary outer race 32 are rotatable in the normal rotation direction (the direction indicated by the arrow in fig. 14) and fixed in the reverse rotation direction (the opposite direction indicated by the arrow in fig. 14) with respect to the first middle race 2. The first pawl 6 is mounted on the first middle ring 2, the first pawl 6 rotating with the first middle ring 2. The first pawl 6 is rotatable relative to the first middle ring 2 within an angular range defined by the first middle ring left bracket 24 and the first middle ring right bracket 25. The third pawls 8 are mounted on the first middle ring 2, and the third pawls 8 rotate together with the first middle ring 2. The third pawls 8 are rotatable with respect to the first middle ring 2 within an angular range defined by the first middle ring left bracket 24 and the first middle ring right bracket 25. The first return spring 10 is mounted on the first middle ring 2, and the first return spring 10 rotates together with the first middle ring 2. The third return spring 30 is installed on the first middle ring 2, and the third return spring 30 rotates together with the first middle ring 2. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. The third return spring 30 is directly connected to the third pawl 8, and when the effect of other restraint or load on the third pawl 8 is smaller than the effect of the third return spring 30 on the third pawl 8, the third pawl 8 returns to the initial position under the effect of the third return spring 30. When the first pawls 6 are in the disengaged state from the first inner race 1, the first inner race 1 is rotatable in both the normal rotation direction (the direction indicated by the arrow in fig. 14) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 14) with respect to the first middle race 2 within a certain angular range. When the third pawls 8 are in the disengaged state from the first outer race 3, the first outer race 3 is rotatable in both the normal rotation direction (the direction indicated by the arrow in fig. 14) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 14) with respect to the first inner race 2 within a certain angular range. As in embodiment 1, by designing the contact angle between the pawl and the ratchet in the engaged state, the pawl and the ratchet can have a certain self-locking function or overload protection function in the engaged state; by designing the specific structure of the pawl and the constraint support conditions, the pawl and the ratchet have certain centrifugal contact-separating function in a separated state. The first middle ring 2, the first middle ring left bracket 24 and the first middle ring right bracket 25 are fixedly connected through the first middle ring rivet 52. The second auxiliary inner ring 12 is fixedly connected with the first inner ring 1 through the first auxiliary inner ring limit pin 61. The first inner ring 1 positions and supports the first auxiliary inner ring 11 in the radial direction and/or the axial direction through the first auxiliary inner ring positioning bearing 16. Under the action of the first pawl 6, the first auxiliary inner ring 11 can rotate relative to the first inner ring 1 within the angle range limited by the first auxiliary inner ring limit pin 61. When the first inner ring 1 is reversely rotated with respect to the first middle ring 2 (in the opposite direction of the arrow in fig. 14), the second auxiliary inner ring 12 is fixed with respect to the first inner ring 1 in the rotational direction; under the action of the first pawl 6, the first auxiliary inner ring 11 rotates to an angle position limited by the first auxiliary inner ring limit pin 61 relative to the first inner ring 1, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are spliced in the axial direction to form a cylindrical surface, and the first pawl 6 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved. When the first pawls 6 are in a disengaged state from the first inner race 1, and when the first inner race 1 is rotated forward relative to the first middle race 2 (in the direction indicated by the arrow in fig. 14), the second auxiliary inner race 12 is fixed relative to the first inner race 1 in the rotational direction; under the action of the first pawl 6, the first auxiliary inner race 11 rotates to an initial angular position relative to the first inner race 1, and at this time, the first pawl 6 is restored to the initial position under the action of the first return spring 10, that is, the first pawl 6 is engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12. The second auxiliary outer ring 32 is fixedly connected with the first outer ring 3 through the first auxiliary outer ring limit pin 81. The first outer ring 3 positions and supports the first auxiliary outer ring 31 radially and/or axially through the first auxiliary outer ring positioning bearing 36. Under the action of the third pawls 8, the first auxiliary outer race 31 is rotatable relative to the first outer race 3 within an angular range defined by the first auxiliary outer race limit pin 81. When the first outer ring 3 is rotated forward relative to the first middle ring 2 (in the direction of the arrow in fig. 14), the second auxiliary outer ring 32 is fixed relative to the first outer ring 3 in the rotational direction; under the action of the third pawls 8, the first auxiliary outer ring 31 rotates to an angle position limited by the first auxiliary outer ring limit pin 81 relative to the first outer ring 3, at this time, the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are axially spliced to form a cylindrical surface, and the third pawls 8 are in contact with the spliced cylindrical surface, so that the vibration and noise of the multi-pawl type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved. When the third pawls 8 are in a disengaged state from the first outer race 3, and when the first outer race 3 is reversed in rotation relative to the first middle race 2 (in the opposite direction indicated by the arrow in fig. 14), the second auxiliary outer race 32 is fixed in the rotational direction relative to the first outer race 3; under the action of the third pawls 8, the first auxiliary outer race 31 rotates to an initial angular position relative to the first outer race 3, and at this time, the third pawls 8 are restored to the initial position under the action of the third return springs 30, that is, the third pawls 8 are in an engaged state with the first outer race 3, the first auxiliary outer race 31, and the second auxiliary outer race 32. As in embodiment 1, the groove profile portions of the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary outer ring 31, and the second auxiliary outer ring 32 are correspondingly deepened to avoid the ratchet roller bearing a large load. The outer diameters of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are slightly larger than the first inner ring 1; the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are slightly smaller than the inner diameter of the first outer ring 3. Otherwise, the procedure is similar to example 1.

Example 4

As shown in fig. 16 to 26, the multi-ratchet mute clutch MRC includes a multi-ratchet clutch MRM, an actuating device AM, and a damping device DM. The multi-ratchet clutch device MRM is a radial multi-mode clutch mechanism 95, as shown in fig. 19 to 21, and includes: the gear shifting device comprises a first inner ring 1, a first outer ring 3, a first pawl 6, a second pawl 7, a first return spring 10, a second return spring 20, a first outer ring left support 34, a first outer ring right support 35, a first outer ring rivet 53, a first auxiliary inner ring 11, a second auxiliary inner ring 12, a first auxiliary inner ring limit pin 61, a first auxiliary inner ring positioning bearing 16, a first outer ring gear shifting positioning mechanism 38 and a first outer ring gear shifting cam 39.

The rotor of the first actuator motor 201 is directly or indirectly connected with the first actuator wire 211, and the first actuator wire 211 rotates together with the rotor of the first actuator motor 201.

The first actuating nut 212 is fixedly connected to the first actuating link 215 by the first actuating connecting bolt 227. The first actuating link 215 is fixedly connected to the first actuating pin 214. Under the action of the first actuating screw 211 and the first rotation-preventing guide rod 213, the first actuating nut 212 can convert the rotation of the first actuating motor 201 into the axial movement of the first actuating pin 214. The transmission efficiency of the screw transmission can be improved by using a ball screw or the like between the first actuating screw 211 and the first actuating nut 212. The first actuating pin 214 is connected to the multi-ratchet clutch MRM via the first outer ring shift cam 39. The first outer ring shift cam 39 is selectively rotatable with respect to the first outer ring 3 by the actuation device AM, so that the multi-ratchet clutch device MRM has a plurality of clutch states. The actuating device AM may also adopt a hydraulic, pneumatic, electromagnetic valve or other driving form, and the multi-ratchet clutch device MRM realizes various engaging and disengaging functions under the action of the actuating device AM. The cushion damper device DM is shown in fig. 24 to 26. The damping device DM is connected to the multi-ratchet clutch MRM via the first inner ring 1. The buffer damping device DM is used for relieving excessive vibration, impact and the like generated by the multi-ratchet type mute clutch MRC in the power clutch process. The buffer damping device DM may also adopt a buffer damping mechanism in the form of hydraulic damping, spring damping, or the like, so as to alleviate excessive vibration, impact, or the like generated by the multi-ratchet type mute clutch MRC during the power clutching process. In the radial direction, the first outer ring 3 is arranged outside the first inner ring 1.

The first inner ring 1, the first outer ring 3, the first auxiliary inner ring 11, and the second auxiliary inner ring 12 are configured with ratchet-like protrusions and grooves having at least a function of engaging and/or disengaging with the first pawls 6 and the second pawls 7. As shown in fig. 20, the first pawls 6 are engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at the initial position, and the second pawls 7 are engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at the initial position, and at this time, the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 are fixed in both the normal rotation direction (the direction indicated by the arrow in fig. 20) and the reverse rotation direction (the reverse direction indicated by the arrow in fig. 20) with respect to the first outer race 3. The first pawl 6 is mounted on the first outer race 3 and the first pawl 6 rotates with the first outer race 3. The first pawls 6 are rotatable with respect to the first outer race 3 within an angular range defined by the first outer-race left bracket 34 and the first outer-race right bracket 35. The second pawls 7 are mounted on the first outer race 3, and the second pawls 7 rotate with the first outer race 3. The second pawls 7 are rotatable with respect to the first outer race 3 within an angular range defined by the first outer-race left bracket 34 and the first outer-race right bracket 35.

The second return spring 20 is installed on the first outer race 3, and the second return spring 20 rotates together with the first outer race 3. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. The second return spring 20 is directly connected to the second pawl 7, and when the action of other restraint or load on the second pawl 7 is smaller than the action of the second return spring 20 on the second pawl 7, the second pawl 7 is returned to the initial position under the action of the second return spring 20. When the first pawls 6 and the second pawls 7 are both engaged with the first inner race 1, the first inner race 1 is fixed relative to the first outer race 3 in both the normal rotation direction (the direction indicated by the arrow in fig. 20) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 20) within a limited load range. When the first pawls 6 are disengaged from the first inner race 1 and the second pawls 7 are engaged with the first inner race 1, the first inner race 1 is fixed relative to the first outer race 3 in the normal rotation direction (the direction indicated by the arrow in fig. 20) and is rotatable in the reverse rotation direction (the opposite direction indicated by the arrow in fig. 20) within a limited load range. When the first pawls 6 are engaged with the first inner race 1 and the second pawls 7 are disengaged from the first inner race 1, the first inner race 1 is fixed in a reverse rotation direction (a reverse direction indicated by an arrow in fig. 20) and is rotatable in a forward rotation direction (a direction indicated by an arrow in fig. 20) with respect to the first outer race 3 within a limited load range. When the first pawls 6 and the second pawls 7 are both disengaged from the first inner race 1, the first inner race 1 is rotatable in both the normal rotation direction (the direction indicated by the arrow in fig. 20) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 20) with respect to the first outer race 3 within a limited load range. As in embodiment 1, by designing the contact angle between the pawl and the ratchet in the engaged state, the pawl and the ratchet can have a certain self-locking function or overload protection function in the engaged state; by designing the specific structure of the pawl and the constraint support conditions, the pawl and the ratchet have certain centrifugal contact-separating function in a separated state.

The first outer ring shift cam 39 is connected to the first pawls 6, and selective rotation of the first outer ring shift cam 39 relative to the first outer ring 3 within a limited angular range brings the first pawls 6 into engagement with or disengagement from the first inner ring 1. The first outer ring shift cam 39 is connected to the second pawls 7, and the second pawls 7 are engaged or disengaged with the first inner ring 1 by selectively rotating the first outer ring shift cam 39 within a limited angular range with respect to the first outer ring 3. The first outer ring shift cam 39 is connected to the actuating device AM via the first actuating pin 214. Under the action of the actuating device AM, the first outer ring shift cam 39 selectively rotates relative to the first outer ring 3 within a limited angular range, and the four clutch states of the multi-ratchet type mute clutch MRC can be switched. The second auxiliary inner ring 12 is fixedly connected with the first inner ring 1 through the first auxiliary inner ring limit pin 61. The first inner ring 1 positions and supports the first auxiliary inner ring 11 in the radial direction and/or the axial direction through the first auxiliary inner ring positioning bearing 16. Under the action of the first pawls 6 and the second pawls 7, the first auxiliary inner race 11 is rotatable relative to the first inner race 1 within an angular range defined by the first auxiliary inner race stopper pin 61. The first outer ring shift positioning mechanism 38 has a positioning function of two angular positions in the normal rotation direction (the direction indicated by the arrow in fig. 20) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 20) for the first outer ring shift cam 39, respectively. The first outer race shift positioning mechanism 38 has a positioning effect of an angular position on the first outer race shift cam 39 at a default intermediate position. In a default intermediate position, the first pawl 6 and the second pawl 7 are both in the initial position. When the first outer-ring shift cam 39 is rotated forward relative to the first outer ring 3 to the first angular position, the first pawls 6 are disengaged from the first inner ring 1 by the first outer-ring shift cam 39, and the second pawls 7 are engaged with the first inner ring 1 by the first outer-ring shift cam 39; at this time, the first inner ring 1 is fixed in the normal rotation direction and rotatable in the reverse rotation direction with respect to the first outer ring 3; when the first inner ring 1 rotates reversely relative to the first outer ring 3 (in the opposite direction of the arrow in fig. 20), under the action of the second pawl 7, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to the angular position defined by the first auxiliary inner ring limit pin 61, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are axially spliced to form a cylindrical surface, and the second pawl 7 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first inner ring 1 rotates forward relative to the first outer ring 3 (in the direction indicated by the arrow in fig. 20), the first auxiliary inner ring 11 rotates to an initial angular position relative to the first inner ring 1 under the action of the second pawl 7, and at this time, the second pawl 7 returns to the initial position under the action of the second return spring 20, that is, the second pawl 7 is engaged with the first inner ring 1, the first auxiliary inner ring 11, and the second auxiliary inner ring 12. When the first outer-ring shift cam 39 is rotated forward relative to the first outer ring 3 to the second positioning angle position, the first pawls 6 are disengaged from the first inner ring 1 by the first outer-ring shift cam 39, and the second pawls 7 are disengaged from the first inner ring 1 by the first outer-ring shift cam 39; at this time, the first inner race 1 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first outer race 3. When the first outer-ring shift cam 39 rotates reversely to the first angular position with respect to the first outer ring 3, the first pawls 6 are engaged with the first inner ring 1 by the first outer-ring shift cam 39, and the second pawls 7 are disengaged from the first inner ring 1 by the first outer-ring shift cam 39; at this time, the first inner ring 1 is rotatable in the normal rotation direction and fixed in the reverse rotation direction with respect to the first outer ring 3; when the first inner ring 1 rotates forward relative to the first outer ring 3 (in the direction indicated by the arrow in fig. 20), under the action of the first pawl 6, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to an angular position defined by the first auxiliary inner ring limit pin 61, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are axially spliced to form a cylindrical surface, and the first pawl 6 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first inner race 1 rotates reversely with respect to the first outer race 3 (in the opposite direction indicated by the arrow in fig. 20), the first auxiliary inner race 11 rotates to an initial angular position with respect to the first inner race 1 by the first pawl 6, and at this time, the first pawl 6 returns to the initial position by the first return spring 10, that is, the first pawl 6 is engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12. When the first outer-ring shift cam 39 rotates reversely with respect to the first outer ring 3 to the second positioning angle position, the first pawls 6 are disengaged from the first inner ring 1 by the first outer-ring shift cam 39, and the second pawls 7 are disengaged from the first inner ring 1 by the first outer-ring shift cam 39; at this time, the first inner race 1 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first outer race 3. As in embodiment 1, the groove profile portions of the first and second auxiliary inner rings 11 and 12 are correspondingly deepened to avoid the pawl roller bearing a large load. The outer diameters of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are slightly larger than the first inner ring 1. Otherwise, the procedure is similar to example 1.

When the first center ring shift cam 29 rotates reversely to the second positioning angle position with respect to the first center ring 2, the third pawls 8 are disengaged from the first outer ring 3 by the first center ring shift cam 29, and the fourth pawls 9 are disengaged from the first outer ring 3 by the first center ring shift cam 29; at this time, the first outer ring 3 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first middle ring 2. As in embodiment 1, the groove profile portions of the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary outer ring 31, and the second auxiliary outer ring 32 are correspondingly deepened to avoid the ratchet roller bearing a large load. The outer diameters of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are slightly larger than the first inner ring 1; the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are slightly smaller than the inner diameter of the first outer ring 3.

As shown in fig. 38, the first pawls 6 are engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at the initial position, and the second pawls 7 are engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at the initial position, and at this time, the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 are fixed in both the forward rotation direction (the direction indicated by the arrow in fig. 38) and the reverse rotation direction (the reverse direction indicated by the arrow in fig. 38) with respect to the first outer race 3. The first pawl 6 is mounted on the first outer race 3 and the first pawl 6 rotates with the first outer race 3. The first pawls 6 are rotatable with respect to the first outer race 3 within an angular range defined by the first outer-race left bracket 34 and the first outer-race right bracket 35. The second pawls 7 are mounted on the first outer race 3, and the second pawls 7 rotate with the first outer race 3.

The second return spring 20 is installed on the first outer race 3, and the second return spring 20 rotates together with the first outer race 3. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. The second return spring 20 is directly connected to the second pawl 7, and when the action of other restraint or load on the second pawl 7 is smaller than the action of the second return spring 20 on the second pawl 7, the second pawl 7 is returned to the initial position under the action of the second return spring 20. When the first pawls 6 and the second pawls 7 are both engaged with the first inner race 1, the first inner race 1 is fixed relative to the first outer race 3 in both the normal rotation direction (the direction indicated by the arrow in fig. 38) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 38) within a limited load range. When the first pawls 6 are disengaged from the first inner race 1 and the second pawls 7 are engaged with the first inner race 1, the first inner race 1 is fixed relative to the first outer race 3 in the normal rotation direction (the direction indicated by the arrow in fig. 38) and is rotatable in the reverse rotation direction (the opposite direction indicated by the arrow in fig. 38) within a limited load range. When the first pawls 6 are engaged with the first inner race 1 and the second pawls 7 are disengaged from the first inner race 1, the first inner race 1 is fixed in a reverse rotation direction (a reverse direction indicated by an arrow in fig. 38) and is rotatable in a forward rotation direction (a direction indicated by an arrow in fig. 38) with respect to the first outer race 3 within a limited load range. When the first pawls 6 and the second pawls 7 are both disengaged from the first inner race 1, the first inner race 1 is rotatable in both the normal rotation direction (the direction indicated by the arrow in fig. 38) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 38) with respect to the first outer race 3 within a limited load range. As in embodiment 1, by designing the contact angle between the pawl and the ratchet in the engaged state, the pawl and the ratchet can have a certain self-locking function or overload protection function in the engaged state; by designing the specific structure of the pawl and the constraint support conditions, the pawl and the ratchet have certain centrifugal contact-separating function in a separated state. The first outer ring 3, the first outer ring left bracket 34 and the first outer ring right bracket 35 are fixedly connected through the first outer ring rivet 53. The first outer ring shift positioning mechanism 38 is mounted on the first outer ring left bracket 34, and the first outer ring shift positioning mechanism 38 rotates with the first outer ring left bracket 34. The first outer race shift positioning mechanism 38 is axially fixed relative to the first outer race left bracket 34. The first outer race shift positioning mechanism 38 has a multi-position positioning effect on the first outer race shift sleeve 37 in the axial direction. The first outer ring gear shift sleeve 37 is connected to the first outer ring left bracket 34 and the first outer ring right bracket 35 through splines. The first outer ring shift sleeve 37 is axially movable relative to the first outer ring left bracket 34 and the first outer ring right bracket 35, and the first outer ring shift sleeve 37 is rotationally fixed relative to the first outer ring left bracket 34 or the first outer ring right bracket 35. The first outer ring drive cam 83 is sleeved on the first outer ring 3, and the first outer ring drive cam 83 can rotate relative to the first outer ring 3. In the axial direction, the first outer-ring transmission cam 83 is confined between the first outer-ring left bracket 34 and the first outer-ring right bracket 35. A bearing may also be added between the first outer ring drive cam 83 and the first outer ring 3 to reduce drive resistance. The first outer ring shift sleeve 37 is configured with a series of detents and/or projections thereon, and the first outer ring shift sleeve 37 is configured to be axially positioned relative to the first outer ring 3 at a plurality of positions within a defined range by the restraining action of the series of detents and/or projections with the first outer ring shift positioning mechanism 38. The first outer race drive pin 84 is fixedly connected to the first outer race shift sleeve 37. The first outer ring drive pin 84 is connected to the first outer ring drive cam 83 via a screw drive pair. When the first outer ring drive pin 84 moves axially with the first outer ring shift gear sleeve 37 relative to the first outer ring 3, the first outer ring drive pin 84 pushes the first outer ring drive cam 83 to rotate relative to the first outer ring 3 through a screw drive pair. A bearing may be added between the first outer ring drive pin 84 and the first outer ring drive cam 83 to improve the transmission efficiency of the screw drive, or a method similar to a ball screw may be used to improve the transmission efficiency of the screw drive. The first outer-ring shift cam 39 is fixedly connected to the first outer-ring transmission cam 83 in the rotational direction, and the first outer-ring shift cam 39 rotates together with the first outer-ring transmission cam 83. And the first outer-ring shift cam 39 is restrained between the first outer-ring drive cam 83 and the first outer-ring right bracket 35 in the axial direction. The first outer ring shift cam 39 is directly connected to the first pawls 6 and the second pawls 7, respectively. And the first outer race shift cam 39 is selectively rotatable within a limited angular range relative to the first outer race 3 to bring the first pawls 6 into engagement or disengagement with the first inner race 1. The selective rotation of the first outer ring shift cam 39 relative to the first outer ring 3 within a defined angular range brings the second pawls 7 into engagement or disengagement with the first inner ring 1. The first outer ring gear sleeve 37 is connected to the actuating device AM via the first shift fork 216. Under the action of the actuating device AM, the first outer ring shift sleeve 37 is selectively moved relative to the first outer ring 3 within a limited axial range, so that the four clutch states of the multi-ratchet type mute clutch MRC can be switched. The second auxiliary inner ring 12 is fixedly connected with the first inner ring 1 through the first auxiliary inner ring limit pin 61. The first inner ring 1 positions and supports the first auxiliary inner ring 11 in the radial direction and/or the axial direction through the first auxiliary inner ring positioning bearing 16. Under the action of the first pawls 6 and the second pawls 7, the first auxiliary inner race 11 is rotatable relative to the first inner race 1 within an angular range defined by the first auxiliary inner race stopper pin 61. The first outer race shift positioning mechanism 38 has a five-position positioning effect on the first outer race shift sleeve 37 in the axial direction. Wherein in a default intermediate position both the first pawl 6 and the second pawl 7 are in the initial position. When the first outer-ring shift sleeve 37 is axially moved to a left (first outer-ring left bracket 34 side) first position with respect to the first outer ring 3, the first pawl 6 is in a disengaged state from the first inner ring 1 by the first outer-ring shift cam 39, and the second pawl 7 is in an engaged state with the first inner ring 1 by the first outer-ring shift cam 39; at this time, the first inner ring 1 is fixed in the normal rotation direction and rotatable in the reverse rotation direction with respect to the first outer ring 3; when the first inner ring 1 rotates reversely relative to the first outer ring 3 (in the opposite direction of the arrow in fig. 38), under the action of the second pawl 7, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to the angular position defined by the first auxiliary inner ring limit pin 61, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are axially spliced to form a cylindrical surface, and the second pawl 7 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first inner race 1 rotates forward relative to the first outer race 3 (in the direction indicated by the arrow in fig. 38), the first auxiliary inner race 11 rotates to an initial angular position relative to the first inner race 1 by the second pawl 7, and at this time, the second pawl 7 returns to the initial position by the second return spring 20, that is, the second pawl 7 is engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12. When the first outer-ring shift sleeve 37 moves axially to a left (first outer-ring left bracket 34 side) second position with respect to the first outer ring 3, the first pawl 6 is in a disengaged state from the first inner ring 1 by the first outer-ring shift cam 39, and the second pawl 7 is in a disengaged state from the first inner ring 1 by the first outer-ring shift cam 39; at this time, the first inner race 1 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first outer race 3. When the first outer-ring shift sleeve 37 is axially moved to a right-side (first outer-ring right bracket 35 side) first position with respect to the first outer ring 3, the first pawl 6 is in an engaged state with the first inner ring 1 by the first outer-ring shift cam 39, and the second pawl 7 is in a disengaged state with the first inner ring 1 by the first outer-ring shift cam 39; at this time, the first inner ring 1 is rotatable in the normal rotation direction and fixed in the reverse rotation direction with respect to the first outer ring 3; when the first inner ring 1 rotates forward relative to the first outer ring 3 (in the direction indicated by the arrow in fig. 38), under the action of the first pawl 6, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to an angular position defined by the first auxiliary inner ring limit pin 61, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are axially spliced to form a cylindrical surface, and the first pawl 6 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first inner race 1 is reversely rotated with respect to the first outer race 3 (in the opposite direction of the arrow in fig. 38), the first auxiliary inner race 11 is rotated to an initial angular position with respect to the first inner race 1 by the first pawl 6, and at this time, the first pawl 6 is restored to an initial engaged state by the first return spring 10, that is, the first pawl 6 is engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12. When the first outer ring shift sleeve 37 moves axially to a second position on the right side (the first outer ring right bracket 35 side) with respect to the first outer ring 3, the first pawl 6 is in a disengaged state from the first inner ring 1 by the first outer ring shift cam 39, and the second pawl 7 is in a disengaged state from the first inner ring 1 by the first outer ring shift cam 39; at this time, the first inner race 1 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first outer race 3. As in embodiment 1, the groove profile portions of the first and second auxiliary inner rings 11 and 12 are correspondingly deepened to avoid the pawl roller bearing a large load. The outer diameters of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 are slightly larger than the first inner ring 1. Otherwise, the procedure is similar to example 1.

In the axial direction, the first middle ring drive pin roller 77 is fixed relative to the first middle ring drive pin 76. The first center ring drive pin roller 77 is connected to the first center ring shift sleeve 27 via a screw drive pair. When the first middle ring shift sleeve 27 is selectively moved in the axial direction relative to the first middle ring 2, the first middle ring shift sleeve 27 pushes the first middle ring pin roller 77 to rotate relative to the first middle ring 2 through a screw gear pair. Further, the first middle ring pin roller 77 pushes the first middle ring shift cam 29 to selectively rotate with respect to the first middle ring 2 through the first middle ring pin 76. A bearing may be added between the first middle ring driving pin 76 and the first middle ring driving pin roller 77 to improve the driving efficiency of the screw driving, or a method similar to a ball screw may be used between the first middle ring driving pin roller 77 and the first middle ring shifting gear sleeve 27 to improve the driving efficiency of the screw driving.

In a default intermediate position, the first pawl 6, the second pawl 7, the third pawl 8, and the fourth pawl 9 are all in the initial position. When the first middle ring shift cam 29 rotates forward relative to the first middle ring 2 to the first positioning angle position, the first pawl 6 is in a disengaged state from the first inner ring 1 under the action of the first middle ring shift cam 29, and the second pawl 7 is in an engaged state with the first inner ring 1 under the action of the first middle ring shift cam 29; at this time, the first inner ring 1 is fixed in the forward rotation direction and rotatable in the reverse rotation direction with respect to the first middle ring 2; when the first inner ring 1 rotates reversely relative to the first middle ring 2 (in the opposite direction of the arrow in fig. 44), under the action of the second pawl 7, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to the angular position defined by the first auxiliary inner ring limit pin 61, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are spliced in the axial direction to form a cylindrical surface, and the second pawl 7 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in the separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first inner ring 1 rotates forward relative to the first middle ring 2 (in the direction indicated by the arrow in fig. 44), the first auxiliary inner ring 11 rotates to an initial angular position relative to the first inner ring 1 by the second pawl 7, and at this time, the second pawl 7 returns to the initial position by the second return spring 20, that is, the second pawl 7 is engaged with the first inner ring 1, the first auxiliary inner ring 11, and the second auxiliary inner ring 12.

When the first center ring shift cam 29 is rotated forward relative to the first center ring 2 to the first positioning angle position, the third pawls 8 are disengaged from the first outer race 3 by the first center ring shift cam 29, and the fourth pawls 9 are engaged with the first outer race 3 by the first center ring shift cam 29; at this time, the first outer ring 3 is fixed in the reverse rotation direction and rotatable in the forward rotation direction with respect to the first middle ring 2; when the first outer ring 3 rotates forward relative to the first middle ring 2 (in the direction indicated by the arrow in fig. 44), under the action of the fourth pawls 9, the first auxiliary outer ring 31 rotates relative to the first outer ring 3 to an angular position defined by the first auxiliary outer ring limit pins 81, at this time, the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are axially spliced to form a cylindrical surface, and the fourth pawls 9 are in contact with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first outer race 3 is reversely rotated with respect to the first middle race 2 (in the opposite direction of the arrow in fig. 44), the first auxiliary outer race 31 is rotated with respect to the first outer race 3 to an initial angular position by the fourth pawls 9, and at this time, the fourth pawls 9 are restored to the initial position by the fourth return spring 40, that is, the fourth pawls 9 are engaged with the first outer race 3, the first auxiliary outer race 31, and the second auxiliary outer race 32. When the first middle ring shift cam 29 is rotated forward relative to the first middle ring 2 to the second positioning angle position, the third pawl 8 is in a disengaged state from the first outer ring 3 by the first middle ring shift cam 29, and the fourth pawl 9 is in a disengaged state from the first outer ring 3 by the first middle ring shift cam 29; at this time, the first outer ring 3 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first middle ring 2. When the first center ring shift cam 29 rotates reversely to the first positioning angle position with respect to the first center ring 2, the third pawls 8 are engaged with the first outer ring 3 by the first center ring shift cam 29, and the fourth pawls 9 are disengaged from the first outer ring 3 by the first center ring shift cam 29; at this time, the first outer ring 3 is rotatable in the reverse rotation direction and fixed in the forward rotation direction with respect to the first middle ring 2; when the first outer ring 3 rotates reversely relative to the first middle ring 2 (in the opposite direction of the arrow in fig. 44), under the action of the third pawls 8, the first auxiliary outer ring 31 rotates relative to the first outer ring 3 to the angular position defined by the first auxiliary outer ring limit pins 81, at this time, the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are axially spliced to form a cylindrical surface, and the third pawls 8 are in contact with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first outer race 3 rotates forward relative to the first middle race 2 (in the direction indicated by the arrow in fig. 44), the first auxiliary outer race 31 rotates relative to the first outer race 3 to an initial angular position by the third pawls 8, and at this time, the third pawls 8 return to the initial position by the third return springs 30, that is, the third pawls 8 are engaged with the first outer race 3, the first auxiliary outer race 31, and the second auxiliary outer race 32. When the first center ring shift cam 29 rotates reversely to the second positioning angle position with respect to the first center ring 2, the third pawls 8 are disengaged from the first outer ring 3 by the first center ring shift cam 29, and the fourth pawls 9 are disengaged from the first outer ring 3 by the first center ring shift cam 29; at this time, the first outer ring 3 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first middle ring 2. As in embodiment 1, the groove profile portions of the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary outer ring 31, and the second auxiliary outer ring 32 are correspondingly deepened to avoid the ratchet roller bearing a large load. The outer diameter of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 is slightly larger than that of the first inner ring 1; the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are slightly smaller than the inner diameter of the first outer ring 3. Otherwise, the procedure is similar to example 1.

The cushion damper device DM is connected to the multi-ratchet clutch device MRM by the first outer ring rivet 53. In the radial direction, the first outer ring 3 is arranged outside the first inner ring 1. In the radial direction, the first outer race 3, the first pawl 6, the second pawl 7, the first return spring 10, the second return spring 20, the first outer race left bracket 34, the first outer race right bracket 35, the first outer race rivet 53, the first auxiliary inner race 11, the second auxiliary inner race 12, the first auxiliary inner race limit pin 61, the first auxiliary inner race limit pin roller 62, the first auxiliary inner race positioning bearing 16, the first outer race shift gear sleeve 37, the first outer race shift positioning mechanism 38, the first lever mechanism 110, the second lever mechanism 120, and the first clutch actuation spring 47 are all arranged coaxially with the first inner race 1.

The first inner ring 1, the first outer ring 3, the first auxiliary inner ring 11, and the second auxiliary inner ring 12 are configured with ratchet-like protrusions and grooves having at least a function of engaging and/or disengaging with the first pawls 6 and the second pawls 7. The first pawls 6 are engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at the initial position, and the second pawls 7 are engaged with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at the initial position, and at this time, the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 are fixed in both the forward rotation direction (the direction indicated by the arrow in fig. 50) and the reverse rotation direction (the reverse direction indicated by the arrow in fig. 50) with respect to the first outer race 3. The first pawl 6 is mounted on the first outer race 3 and the first pawl 6 rotates with the first outer race 3. The first pawls 6 are rotatable with respect to the first outer race 3 within an angular range defined by the first outer-race left bracket 34 and the first outer-race right bracket 35. The second pawls 7 are mounted on the first outer race 3, and the second pawls 7 rotate with the first outer race 3. The second pawls 7 are rotatable with respect to the first outer race 3 within an angular range defined by the first outer-race left bracket 34 and the first outer-race right bracket 35. The first return spring 10 is mounted on the first outer race 3, and the first return spring 10 rotates with the first outer race 3. The second return spring 20 is installed on the first outer race 3, and the second return spring 20 rotates together with the first outer race 3. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. The second return spring 20 is directly connected to the second pawl 7, and when the action of other restraint or load on the second pawl 7 is smaller than the action of the second return spring 20 on the second pawl 7, the second pawl 7 is returned to the initial position under the action of the second return spring 20. When the first pawls 6 and the second pawls 7 are both engaged with the first inner race 1, the first inner race 1 is fixed relative to the first outer race 3 in both the normal rotation direction (the direction indicated by the arrow in fig. 50) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 50) within a limited load range. When the first pawls 6 are disengaged from the first inner race 1 and the second pawls 7 are engaged with the first inner race 1, the first inner race 1 is fixed relative to the first outer race 3 in the normal rotation direction (the direction indicated by the arrow in fig. 50) and is rotatable in the reverse rotation direction (the opposite direction indicated by the arrow in fig. 50) within a limited load range. When the first pawls 6 and the second pawls 7 are both disengaged from the first inner race 1, the first inner race 1 is rotatable in both the normal rotation direction (the direction indicated by the arrow in fig. 50) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 50) with respect to the first outer race 3 within a limited load range. As in embodiment 1, by designing the contact angle between the pawl and the ratchet in the engaged state, the pawl and the ratchet can have a certain self-locking function or overload protection function in the engaged state; by designing the specific structure of the pawl and the constraint support conditions, the pawl and the ratchet have certain centrifugal contact-separating function in a separated state. The first outer ring 3, the first outer ring left bracket 34 and the first outer ring right bracket 35 are fixedly connected through the first outer ring rivet 53. The first outer ring shift positioning mechanism 38 is mounted on the first outer ring 3, and the first outer ring shift positioning mechanism 38 rotates together with the first outer ring 3. The first outer race shift positioning mechanism 38 is axially fixed relative to the first outer race 3. The first outer race shift positioning mechanism 38 has a multi-position positioning effect on the first outer race shift sleeve 37 in the axial direction. The first outer ring shift sleeve 37 is connected to the first outer ring 3 by splines. The first outer ring shift sleeve 37 is axially movable relative to the first outer ring 3, and the first outer ring shift sleeve 37 is rotationally fixed relative to the first outer ring 3. The first outer ring shift sleeve 37 is configured with a series of detents and/or projections thereon, and the first outer ring shift sleeve 37 is configured to be axially positioned relative to the first outer ring 3 at a plurality of positions within a defined range by the restraining action of the series of detents and/or projections with the first outer ring shift positioning mechanism 38. The first clutch actuation spring 47 is mounted on the first outer race shift sleeve 37. The first lever mechanism 110 is mounted on the first outer-ring left bracket 34, and one end of the first lever mechanism 110 is connected to the first outer-ring shift sleeve 37 through the first clutch actuation spring 47. The other end of the first lever mechanism 110 is connected to the first pawl 6. When the first outer ring shift sleeve 37 is selectively moved in the axial direction with respect to the first outer ring 3 by the actuating device AM, the first outer ring shift sleeve 37 pushes one end of the first lever mechanism 110 by the first clutch actuating spring 47, and the first lever mechanism 110 pushes the first pawl 6 at the other end to cause the first pawl 6 to engage with or disengage from the first inner ring 1. The second lever mechanism 120 is mounted on the first outer ring left bracket 34, and a gap exists between one end of the second lever mechanism 120 and the first outer ring gear shift sleeve 37. The other end of the second lever mechanism 120 is connected to the second pawl 7. When the first outer ring shift sleeve 37 actuates the first lever mechanism 110 by the first clutch actuation spring 47, the second lever mechanism 120 remains in the initial state. As the first outer ring shift sleeve 37 continues to move axially, the first outer ring shift sleeve 37 pushes the second lever mechanism 120, thereby causing the second pawl 7 to engage or disengage the first inner ring 1. At the same time, due to the compressibility of the first clutch actuation spring 47, the first outer ring shift gear sleeve 37 continues to compress the first clutch actuation spring 47 and the first pawl 6 continues to remain disengaged from the first inner ring 1. The first outer ring gear sleeve 37 is connected to the actuating device AM via the first shift fork 216. Under the action of the actuating device AM, the first outer ring shift sleeve 37 is selectively moved relative to the first outer ring 3 within a limited axial range, so that the switching of the three clutch states of the multi-ratchet mute clutch MRC can be realized. The second auxiliary inner ring 12 is fixedly connected with the first inner ring 1 through the first auxiliary inner ring limit pin 61. The first inner ring 1 positions and supports the first auxiliary inner ring 11 in the radial direction and/or the axial direction through the first auxiliary inner ring positioning bearing 16. The first auxiliary inner ring limit pin 61 is connected with the first auxiliary inner ring 11 through the first auxiliary inner ring limit pin roller 62. Under the action of the first pawls 6 and the second pawls 7, the first auxiliary inner race 11 is rotatable relative to the first inner race 1 within an angular range defined by the first auxiliary inner race stopper pin 61. The first outer ring shift positioning mechanism 38 has a positioning function at three positions, i.e., a left position (a side close to the first outer ring left bracket 34), a middle position, and a right position (a side close to the first outer ring right bracket 35) for the first outer ring shift sleeve 37 in the axial direction. With the right side being the default detent position, with the first outer race shift sleeve 37 in this position, the first pawl 6 and the second pawl 7 are both in the initial position. When the first outer ring shift sleeve 37 is axially moved to the intermediate position with respect to the first outer ring 3, the first pawl 6 is in a disengaged state from the first inner ring 1 by the first lever mechanism 110, and the second pawl 7 is in an engaged state with the first inner ring 1 by the second lever mechanism 120; at this time, the first inner ring 1 is fixed in the normal rotation direction and rotatable in the reverse rotation direction with respect to the first outer ring 3; when the first inner ring 1 rotates reversely relative to the first outer ring 3 (in the opposite direction of the arrow shown in fig. 50), under the action of the second pawl 7, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to the angular position defined by the first auxiliary inner ring limit pin 61, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are spliced in the axial direction to form a cylindrical surface, and the second pawl 7 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in the separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first inner ring 1 rotates forward relative to the first outer ring 3 (in the direction indicated by the arrow in fig. 50), the first auxiliary inner ring 11 rotates to an initial angular position relative to the first inner ring 1 by the second pawl 7, and at this time, the second pawl 7 returns to the initial position by the second return spring 20, that is, the second pawl 7 is engaged with the first inner ring 1, the first auxiliary inner ring 11, and the second auxiliary inner ring 12. When the first outer ring shift sleeve 37 moves axially to the left position with respect to the first outer ring 3, the first pawl 6 is in a disengaged state from the first inner ring 1 by the first lever mechanism 110, and the second pawl 7 is in a disengaged state from the first inner ring 1 by the second lever mechanism 120; at this time, the first inner race 1 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first outer race 3. As in embodiment 1, the groove profile portions of the first and second auxiliary inner rings 11 and 12 are correspondingly deepened to avoid the pawl roller bearing a large load. The outer diameter of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 is slightly larger than the outer diameter of the first inner ring 1. Otherwise, the procedure is similar to example 1.

When the third pawls 8 are disengaged from the first outer race 3 and the fourth pawls 9 are engaged with the first outer race 3, the first outer race 3 is fixed in the reverse rotation direction (the reverse direction indicated by the arrow in fig. 56) and is rotatable in the forward rotation direction (the direction indicated by the arrow in fig. 56) with respect to the first inner race 2 within a limited load range. When the third pawls 8 and the fourth pawls 9 are disengaged from the first outer race 3, the first outer race 3 is rotatable in both the normal rotation direction (the direction indicated by the arrow in fig. 56) and the reverse rotation direction (the opposite direction indicated by the arrow in fig. 56) with respect to the first inner race 2 within a limited load range. As in embodiment 1, by designing the contact angle between the pawl and the ratchet in the engaged state, the pawl and the ratchet can have a certain self-locking function or overload protection function in the engaged state; by designing the specific structure of the pawl and the constraint support conditions, the pawl and the ratchet have certain centrifugal contact-separating function in a separated state. The first middle ring 2, the first middle ring left bracket 24 and the first middle ring right bracket 25 are fixedly connected through the first middle ring rivet 52. The first center ring shift positioning mechanism 28 is mounted on the first center ring right bracket 25, and the first center ring shift positioning mechanism 28 rotates together with the first center ring right bracket 25. The first center ring shift positioning mechanism 28 is axially fixed relative to the first center ring right bracket 25.

The first center ring shift sleeve 27 is axially movable relative to the first center ring right bracket 25, and the first center ring shift sleeve 27 is fixed relative to the first center ring right bracket 25 in the rotational direction. The first middle ring shift sleeve 27 is configured with a series of positioning grooves and/or projections, and the first middle ring shift sleeve 27 is configured to perform a plurality of positions in the axial direction with respect to the first middle ring 2 within a limited range by a restraining action of the series of positioning grooves and/or projections and the first middle ring shift positioning mechanism 28.

The first lever mechanism 110 is mounted on the first middle ring right bracket 25, and one end of the first lever mechanism 110 is connected with the first outer ring shift gear sleeve 37 through the first clutch actuation spring 47. The other end of the first lever mechanism 110 is connected to the first pawl 6. When the first outer ring shift sleeve 37 is selectively moved in the axial direction with respect to the first outer ring 3 by the actuating device AM, the first outer ring shift sleeve 37 pushes one end of the first lever mechanism 110 by the first clutch actuating spring 47, and the first lever mechanism 110 pushes the first pawl 6 at the other end to cause the first pawl 6 to engage with or disengage from the first inner ring 1. The second lever mechanism 120 is mounted on the first middle ring right bracket 25, and a gap exists between one end of the second lever mechanism 120 and the first outer ring gear shift sleeve 37. The other end of the second lever mechanism 120 is connected to the second pawl 7. When the first outer ring shift sleeve 37 actuates the first lever mechanism 110 by the first clutch actuation spring 47, the second lever mechanism 120 remains in the initial state. As the first outer ring shift sleeve 37 continues to move axially, the first outer ring shift sleeve 37 pushes the second lever mechanism 120, thereby causing the second pawl 7 to engage or disengage the first inner ring 1. At the same time, due to the compressibility of the first clutch actuation spring 47, the first outer ring shift gear sleeve 37 continues to compress the first clutch actuation spring 47 and the first pawl 6 continues to remain disengaged from the first inner ring 1. The second clutch actuation spring 48 is mounted on the first outer race shift sleeve 37. The third lever mechanism 130 is mounted on the first middle ring right bracket 25, and one end of the third lever mechanism 130 is connected to the first outer ring shift sleeve 37 through the second clutch actuation spring 48. The other end of the third lever mechanism 130 is connected to the third pawl 8. When the first outer ring shift sleeve 37 is selectively moved in the axial direction relative to the first outer ring 3 by the actuating device AM, the first outer ring shift sleeve 37 pushes one end of the third lever mechanism 130 through the second clutch actuating spring 48, and the third lever mechanism 130 pushes the third pawl 8 at the other end to cause the third pawl 8 to engage with or disengage from the first outer ring 3. The fourth lever mechanism 140 is mounted on the first middle ring right bracket 25, and a gap exists between one end of the fourth lever mechanism 140 and the first outer ring gear shift sleeve 37. The other end of the fourth lever mechanism 140 is connected to the fourth pawl 9. When the first outer ring shift sleeve 37 actuates the third lever mechanism 130 by the second clutch actuation spring 48, the fourth lever mechanism 140 remains in the initial state. As the first outer ring shift sleeve 37 continues to move axially, the first outer ring shift sleeve 37 pushes the fourth lever mechanism 140, thereby causing the fourth pawl 9 to engage or disengage the first outer ring 3. At the same time, due to the compressibility of the second clutch actuation spring 48, the first outer race shift sleeve 37 continues to compress the second clutch actuation spring 48 and the third pawls 8 continue to remain disengaged from the first outer race 3. The first middle ring gear sleeve 27 is connected to the actuator AM via the first shift fork 216. Under the action of the actuating device AM, the first middle ring shift gear sleeve 27 is selectively moved in a limited axial range relative to the first middle ring 2, and the switching of the three clutch states of the multi-ratchet type mute clutch MRC can be realized. The second auxiliary inner ring 12 is fixedly connected with the first inner ring 1 through the first auxiliary inner ring limit pin 61. The first inner ring 1 positions and supports the first auxiliary inner ring 11 in the radial direction and/or the axial direction through the first auxiliary inner ring positioning bearing 16. Under the action of the first pawls 6 and the second pawls 7, the first auxiliary inner race 11 is rotatable relative to the first inner race 1 within an angular range defined by the first auxiliary inner race stopper pin 61. The second auxiliary outer ring 32 is fixedly connected with the first outer ring 3 through the first auxiliary outer ring limit pin 81. The first auxiliary outer ring limit pin 81 radially positions and supports the first auxiliary outer ring 31 through the first auxiliary outer ring positioning bearing 36. Under the action of the third pawls 8 and the fourth pawls 9, the first auxiliary outer race 31 is rotatable relative to the first outer race 3 within an angular range defined by the first auxiliary outer race limit pin 81. The first middle ring shift positioning mechanism 28 has positioning functions of three positions, i.e., a left position (a side close to the first middle ring left bracket 24), a middle position and a right position (a side close to the first middle ring right bracket 25) on the first middle ring shift sleeve 27 in the axial direction. Wherein the right side is the default positioning position, and when the first middle ring shift gear sleeve 27 is in this position, the first pawl 6, the second pawl 7, the third pawl 8, and the fourth pawl 9 are all in the initial position. When the first middle ring shift sleeve 27 is axially moved to the intermediate position with respect to the first middle ring 2, the first pawl 6 is in a disengaged state from the first inner ring 1 by the first lever mechanism 110, and the second pawl 7 is in an engaged state with the first inner ring 1 by the second lever mechanism 120; at this time, the first inner ring 1 is fixed in the reverse rotation direction and rotatable in the normal rotation direction with respect to the first middle ring 2; when the first inner ring 1 rotates forward relative to the first middle ring 2 (in the direction indicated by the arrow in fig. 56), under the action of the second pawl 7, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to an angular position defined by the first auxiliary inner ring limit pin 61, at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are axially spliced to form a cylindrical surface, and the second pawl 7 contacts with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first inner race 1 is reversely rotated with respect to the first middle race 2 (in the opposite direction of the arrow in fig. 56), the first auxiliary inner race 11 is rotated to an initial angular position with respect to the first inner race 1 by the second pawl 7, and at this time, the second pawl 7 is restored to the initial position by the second return spring 20, that is, the second pawl 7 is in an engaged state with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12. When the first middle ring shift sleeve 27 is axially moved to the intermediate position with respect to the first middle ring 2, the third pawl 8 is in a disengaged state from the first outer ring 3 by the third lever mechanism 130, and the fourth pawl 9 is in an engaged state with the first outer ring 3 by the fourth lever mechanism 140; at this time, the first outer ring 3 is fixed in the reverse rotation direction and rotatable in the forward rotation direction with respect to the first middle ring 2; when the first outer ring 3 rotates forward relative to the first middle ring 2 (in the direction indicated by the arrow in fig. 56), under the action of the fourth pawls 9, the first auxiliary outer ring 31 rotates relative to the first outer ring 3 to an angular position defined by the first auxiliary outer ring limit pins 81, at this time, the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are axially spliced to form a cylindrical surface, and the fourth pawls 9 are in contact with the spliced cylindrical surface, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved; on this basis, when the first outer race 3 is reversely rotated with respect to the first middle race 2 (in the opposite direction of the arrow in fig. 56), the first auxiliary outer race 31 is rotated with respect to the first outer race 3 to an initial angular position by the fourth pawls 9, and at this time, the fourth pawls 9 are restored to the initial position by the fourth return spring 40, that is, the fourth pawls 9 are engaged with the first outer race 3, the first auxiliary outer race 31, and the second auxiliary outer race 32. When the first middle ring shift sleeve gear 27 is axially moved to the left position with respect to the first middle ring 2, the first pawl 6 is in a disengaged state from the first inner ring 1 by the first lever mechanism 110, and the second pawl 7 is in a disengaged state from the first inner ring 1 by the second lever mechanism 120; at this time, the first inner race 1 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first middle race 2. When the first middle ring shift sleeve 27 is axially moved to the left position with respect to the first middle ring 2, the third pawl 8 is in a disengaged state from the first outer ring 3 by the third lever mechanism 130, and the fourth pawl 9 is in a disengaged state from the first outer ring 3 by the fourth lever mechanism 140; at this time, the first outer ring 3 is rotatable in both the normal rotation direction and the reverse rotation direction with respect to the first middle ring 2. As in embodiment 1, the groove profile portions of the first auxiliary inner ring 11, the second auxiliary inner ring 12, the first auxiliary outer ring 31, and the second auxiliary outer ring 32 are correspondingly deepened to avoid the ratchet roller bearing a large load. The outer diameter of the first auxiliary inner ring 11 and the second auxiliary inner ring 12 is slightly larger than that of the first inner ring 1; the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are slightly smaller than the inner diameter of the first outer ring 3. Otherwise, the procedure is similar to example 1.

Example 10

The multi-ratchet type mute clutch MRC includes a multi-ratchet clutch device MRM as shown in fig. 59 to 61. The multi-ratchet clutch device MRM is a radial one-way clutch mechanism 91, as shown in fig. 59 to 61, and includes: the positioning device comprises a first inner ring 1, a first outer ring 3, a first pawl 6, a first return spring 10, a first outer ring left support 34, a first outer ring right support 35, a first outer ring rivet 53, a first auxiliary inner ring 11, a second auxiliary inner ring 12, a first auxiliary inner ring limiting pin 61 and a first auxiliary inner ring positioning bearing 16. The first pawl 6 is mounted on the first outer race 3, the first pawl 6 rotating with the first outer race 3. In the axial direction, the first pawls 6 are confined between the first outer-ring left bracket 34 and the first outer-ring right bracket 35. The first pawls 6 are arranged radially on the first outer race 3, and the first pawls 6 are radially movable relative to the first outer race 3 within a limited range. As shown in fig. 59, the first pawls 6 are in an engaged state with the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 at an initial position, and at this time, the first inner race 1, the first auxiliary inner race 11, and the second auxiliary inner race 12 are fixed in a reverse rotation direction (a reverse direction indicated by an arrow in fig. 59) and rotatable in a normal rotation direction (a direction indicated by an arrow in fig. 59) with respect to the first outer race 3. The first outer ring 3, the first outer ring left bracket 34 and the first outer ring right bracket 35 are fixedly connected through the first outer ring rivet 53. The first return spring 10 is mounted on the first outer race 3, the first return spring 10 rotating with the first outer race 3. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. Within a certain rotational speed range, the first pawl 6 has a certain function of centrifugal disengaging contact with the first inner race 1 in a disengaged state. At higher rotational speeds, the first pawl 6, under the effect of centrifugal force, overcomes the spring force of the first return spring 10 and other constraining effects and is thus out of contact with the first inner race 1. In this way, the multi-ratchet type mute clutch MRC can realize the function of a safety clutch by limiting the excessive rotation speed of the first outer race 3. Otherwise, the procedure is similar to example 1.

The first inner ring 1 axially and/or radially supports and positions the first outer ring 3 through the first clutch positioning bearing 4. As shown in fig. 63. In order to avoid interference of the first clutch positioning bearing 4, the first pawl 6 is provided with a corresponding notch at a position axially overlapping the first clutch positioning bearing 4. By designing the contact angle of the pawl and the ratchet wheel in the joint state, the pawl and the ratchet wheel can have a certain self-locking function or overload protection function in the joint state. Because the first pawl 6 is radially arranged on the first inner ring 1, and the first pawl 6 can radially move relative to the first inner ring 1, when the rotating speed of the first inner ring 1 is high, the first pawl 6 and the first outer ring 3 cannot automatically separate because the centrifugal force applied to the first pawl 6 is consistent with the elastic force direction of the first return spring 10. Otherwise, the same procedure as in example 10 was repeated.

Example 14

The multi-ratchet type mute clutch MRC includes a multi-ratchet clutch device MRM as shown in fig. 71 to 73. The multi-ratchet clutch device MRM is an axial one-way clutch mechanism 92, as shown in fig. 71 to 73, and includes: the first left half clutch 101, the first right half clutch 103, the first pawl 6, the first return spring 10, the first left half clutch right bracket 115, the first left half clutch rivet 151, the first auxiliary right half clutch 131, the second auxiliary right half clutch 132, the first auxiliary right half clutch limit pin 181, and the first auxiliary right half clutch positioning bearing 136. In the radial direction, the first right half clutch 103, the first pawl 6, the first return spring 10, the first left half clutch right bracket 115, the first left half clutch rivet 151, the first auxiliary right half clutch 131, the second auxiliary right half clutch 132, the first auxiliary right half clutch limit pin 181, and the first auxiliary right half clutch positioning bearing 136 are all coaxially arranged with the first left half clutch 101. In the axial direction, the first right half clutch 103, the first pawl 6, the first return spring 10, the first left half clutch right bracket 115, the first auxiliary right half clutch 131, the second auxiliary right half clutch 132, the first auxiliary right half clutch limit pin 181, and the first auxiliary right half clutch positioning bearing 136 are all disposed on the right side of the first left half clutch 101. The first left half clutch 101, the first right half clutch 103, the first auxiliary right half clutch 131, and the second auxiliary right half clutch 132 are configured with ratchet-shaped protrusions and recesses, and the ratchet-shaped protrusions and recesses at least have a function of engaging with and/or disengaging from the first pawl 6. As shown in fig. 71, the first pawl 6 is engaged with the first right clutch half 103 at the initial position, and the first right clutch half 103 is fixed to the first left clutch half 101 in the reverse rotation direction (the direction opposite to the arrow in fig. 71) and rotatable in the normal rotation direction (the direction indicated by the arrow in fig. 71). The first pawl 6 is engaged with the first auxiliary right half clutch 131 at an initial position, and the first auxiliary right half clutch 131 is fixed to the first left half clutch 101 in a reverse rotation direction (a direction opposite to an arrow in fig. 71) and is rotatable in a normal rotation direction (an arrow in fig. 71). The first pawl 6 is engaged with the second auxiliary right half clutch 132 in the initial position, and the second auxiliary right half clutch 132 is fixed to the first left half clutch 101 in the reverse rotation direction (the direction opposite to the arrow in fig. 71) and is rotatable in the normal rotation direction (the direction of the arrow in fig. 71). The first pawl 6 is mounted on the first left clutch half 101, and the first pawl 6 rotates together with the first left clutch half 101. The first pawl 6 is rotatable relative to the first left clutch half 101 within an angular range defined by the first left clutch half right bracket 115. The first return spring 10 is mounted on the first left clutch half 101, and the first return spring 10 rotates together with the first left clutch half 101. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. When the first pawls 6 and the first right clutch half 103 are disengaged, the first right clutch half 103 is rotatable in a normal rotation direction (a direction indicated by an arrow in fig. 71) and a reverse rotation direction (a direction opposite to the direction indicated by an arrow in fig. 71) with respect to the first left clutch half 101 within a certain angular range. The first left-half clutch 101 and the first left-half clutch right bracket 115 are fixedly connected through the first left-half clutch rivet 151. The second auxiliary right half clutch 132 is fixedly connected with the first right half clutch 103 through the first auxiliary right half clutch limit pin 181. The second auxiliary right half clutch 132 positions and supports the first auxiliary right half clutch 131 radially and/or axially by the first auxiliary right half clutch positioning bearing 136. Under the action of the first pawl 6, the first auxiliary right clutch half 131 can rotate relative to the first right clutch half 103 within the angle range defined by the first auxiliary right clutch half limit pin 181. When the first right half clutch 103 rotates in the forward direction (the direction indicated by the arrow in fig. 71) with respect to the first left half clutch 101, the second auxiliary right half clutch 132 is fixed in the rotational direction with respect to the first right half clutch 103; under the action of the first pawl 6, when the first auxiliary right half clutch 131 rotates to an angle limited by the first auxiliary right half clutch limit pin 181 relative to the first right half clutch 103, the end surface of the first auxiliary right half clutch 131 and the end surface of the second auxiliary right half clutch 132 are radially split into a plane, and the first pawl 6 contacts with the split plane, so that the vibration and noise of the multi-ratchet type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved. When the first pawl 6 is in a disengaged state from the first right half clutch 103 and when the first right half clutch 103 is reversed with respect to the first left half clutch 101 (in the opposite direction indicated by the arrow in fig. 71), the second auxiliary right half clutch 132 is fixed with respect to the first right half clutch 103 in the rotational direction; under the action of the first pawl 6, the first auxiliary right half clutch 131 rotates to an initial angular position relative to the first right half clutch 103, and at this time, the first pawl 6 returns to the initial position under the action of the first return spring 10, that is, the first pawl 6 is engaged with the first right half clutch 103, the first auxiliary right half clutch 131, and the second auxiliary right half clutch 132. In order to avoid that the pawl roller is stressed greatly when the first pawl 6 and the first right half clutch 103 are in the engaged state, the groove tooth profile parts of the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 are correspondingly dug. Thereby ensuring that the pawl roller does not bear a large load even when the first pawl 6 is engaged with the first right half clutch 103 under severe operating conditions. In the axial direction, the end surface of the first auxiliary right half clutch 131 and the end surface of the second auxiliary right half clutch 132 are on the same plane perpendicular to the axis. The end surfaces of the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 and the end surface of the first right half clutch 103 are on the same plane perpendicular to the axis. Alternatively, the end surfaces of the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 slightly protrude to the left (the first left half clutch 101 side in the axial direction) from the end surface of the first right half clutch 103; thus, when the first pawl 6 and the first right half clutch 103 are in a separated state, the contact area between the pawl and the ratchet wheel can be further reduced, and the idle running efficiency of the clutch in the separated state can be further improved; even if the axial dimensions of the end faces of the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 are reduced due to long-term operation, the first pawl 6 can still be ensured not to contact with the first right half clutch 103 in a separated state, so that the engagement and separation performance of the pawl and the ratchet wheel is not influenced, and the reliability of the whole clutch can be improved to a certain extent. Moreover, the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 only serve the purposes of reducing vibration and noise and increasing transmission efficiency, and the strength requirements of the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 are not high, so that the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 can be manufactured in a large batch by adopting light metal, nonmetal or composite materials according to actual working conditions, and thus, the cost can be greatly saved. And the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132 can also be connected through a bearing to connect the two into a component, or the inner and outer rings of the bearing are respectively manufactured into the shapes of the first auxiliary right half clutch 131 and the second auxiliary right half clutch 132, so that the mass production, the manufacturing and the assembly are more convenient, and the cost is further reduced. Otherwise, the procedure is similar to example 1.

The multi-ratchet type mute clutch MRC includes a multi-ratchet clutch device MRM as shown in fig. 137 to 139. The multi-ratchet clutch device MRM is a radial one-way clutch mechanism 91, as shown in fig. 137 to 139, and includes: the first inner race 1, the first outer race 3, the first pawl 6, the first return spring 10, the first pawl holder 56, the first clutch positioning roller 58, the first auxiliary inner race 11, the first auxiliary inner race positioning bearing 16, the first auxiliary inner race limit pin 61, the first auxiliary outer race 31, the first auxiliary outer race positioning bearing 36, and the first auxiliary outer race limit pin 81. In the radial direction, the first outer ring 3 is arranged outside the first inner ring 1. In the radial direction, the first outer race 3, the first pawls 6, the first return spring 10, the first pawl holder 56, the first clutch positioning roller 58, the first auxiliary inner race 11, the first auxiliary inner race positioning bearing 16, the first auxiliary inner race limit pin 61, the first auxiliary outer race 31, the first auxiliary outer race positioning bearing 36, and the first auxiliary outer race limit pin 81 are all arranged coaxially with the first inner race 1. The first inner race 1, the first auxiliary inner race 11, the first outer race 3, and the first auxiliary outer race 31 are configured with ratchet-like projections and recesses that have at least a function of engaging with and/or disengaging from the first pawls 6. As shown in fig. 137, the first pawls 6 are in an engaged state with the first inner race 1, the first auxiliary inner race 11, the first outer race 3, and the first auxiliary outer race 31 in an initial position, in which the first inner race 1 is fixed with respect to the first outer race 3 in a normal rotation direction (a direction indicated by an arrow in fig. 1) and is rotatable in a reverse rotation direction (a direction opposite to that indicated by an arrow in fig. 137). The first pawl 6 is mounted on the first pawl holder 56, and the first pawl 6 rotates together with the first pawl holder 56. The first pawls 6 are rotatable relative to the first pawl holder 56 within an angular range defined by the first pawl holder 56. The first return spring 10 is mounted on the first pawl holder 56, the first return spring 10 rotating with the first pawl holder 56. The first return spring 10 is directly connected to the first pawl 6, and when the other restraint or load acts on the first pawl 6 less than the first return spring 10 acts on the first pawl 6, the first pawl 6 returns to the initial position under the action of the first return spring 10. The first clutch positioning roller 58 is mounted on the first pawl cage 56. The first inner ring 1 positions and supports the first outer ring 3 radially and/or axially by means of the first clutch positioning rollers 58.

As in embodiment 1, by designing the contact angle between the pawl and the ratchet in the engaged state, the pawl and the ratchet can have a certain self-locking function or overload protection function in the engaged state; by designing the specific structure of the pawl and the constraint support conditions, the pawl and the ratchet have certain centrifugal contact-separating function in a separated state. The first auxiliary inner ring limit pin 61 is fixedly connected with the first inner ring 1. The first inner ring 1 positions and supports the first auxiliary inner ring 11 in the radial direction and/or the axial direction through the first auxiliary inner ring positioning bearing 16. Under the action of the first pawl 6, the first auxiliary inner ring 11 can rotate relative to the first inner ring 1 within the angle range limited by the first auxiliary inner ring limit pin 61. The first auxiliary outer ring limit pin 81 is fixedly connected with the first outer ring 3. The first outer ring 3 positions and supports the first auxiliary outer ring 31 radially and/or axially through the first auxiliary outer ring positioning bearing 36. Under the action of the first pawls 6, the first auxiliary outer race 31 is rotatable relative to the first outer race 3 within an angular range defined by the first auxiliary outer race limit pin 81. When the first inner ring 1 rotates reversely relative to the first outer ring 3 (in the opposite direction of the arrow shown in fig. 137), under the action of the first pawl 6, the first auxiliary inner ring 11 rotates relative to the first inner ring 1 to the angular position defined by the first auxiliary inner ring limit pin 61, and at this time, the outer diameter of the first auxiliary inner ring 11 and the outer diameter of the second auxiliary inner ring 12 are spliced together in the axial direction to form a cylindrical surface; under the action of the first pawls 6, the first auxiliary outer ring 31 rotates relative to the first outer ring 3 to an angular position defined by the first auxiliary outer ring limit pin 81, and at this time, the inner diameter of the first auxiliary outer ring 31 and the inner diameter of the second auxiliary outer ring 32 are axially spliced to form a cylindrical surface; two ends of the first pawl 6 are respectively contacted with the spliced cylindrical surfaces, so that the vibration and noise of the multi-pawl-wheel type mute clutch MRC in a separated state are greatly reduced, and the transmission efficiency is improved. When the first pawl 6 is in a disengaged state with respect to the first inner race 1 and when the first inner race 1 rotates forward with respect to the first outer race 3 (in a direction indicated by an arrow in fig. 137), under the action of the first pawl 6, the first auxiliary inner race 11 rotates to an initial angular position with respect to the first inner race 1, and the first auxiliary outer race 31 rotates to an initial angular position with respect to the first outer race 3, at this time, the first pawl 6 returns to the initial position under the action of the first return spring 10, that is, the first pawl 6 is in an engaged state with the first inner race 1, the first auxiliary inner race 11, the first outer race 3, and the first auxiliary outer race 31. Otherwise, the procedure is similar to example 1.
