Description

A vehicle equipped with a continuously variable transmission and a continuously variable transmission

The present invention relates to a vehicle including a CVT and a CVT. The present invention particularly relates to an apparatus for actively adjusting the gear ratio of a CVT regardless of centrifugal force.

Continuously variable transmission (CVT) is known in the art for various configurations. Due to the continuously variable transmission, a suitable transmission ratio can be obtained in each case in comparison with a transmission having a fixed gear in the vehicle. Particular applications of this type of CVT, especially centrifugal force controlled, are small vehicles such as two-wheeled, three-wheeled, so-called tuk-tuks, snowmobiles, quads or scooters.

For these CVTs, a mechanical centrifugal force regulator is often used to adjust the position of the drive belt in the V-pulley. This mechanical centrifugal force regulator is located on the primary side of the CVT. The primary side lies directly on the crankshaft. The secondary side achieves moment and force balances with the primary side. The primary and secondary sides are connected, for example, by drive belts, which are power transmission means. Depending on the load and speed, the centrifugal force of the mechanical centrifugal force regulator is shifted in its radial position, thereby changing the axial distance between the two conical counter-pulleys, also called cone pulleys. So that the drive belt moves at a radius determined by the pulley spacing.

Depending on the speed, the centrifugal force of the centrifugal force regulator is moved in its radial position, thereby changing the axial distance between the cone pulleys, thereby changing the speed ratio of the transmission.

However, the disadvantage of this device is that it is not possible to control or regulate the primary transmission ratio of the CVT. As a result, CVTs having centrifugal force regulators of the prior art generally do not operate at optimum points, so fuel economy and / or vehicle emissions deteriorate. It would therefore be desirable to exploit this potential in centrifugally controlled CVTs and obtain the potential for fuel reduction and emission reduction.

Also, centrifugal-controlled CVTs do not have optimal design for vehicle dynamics. There is still room for improvement, especially when the vehicle is accelerated from standstill and when the vehicle is accelerated from first speed to second speed during running, e.g., elasticity, since it is not an optimal gear ratio of centrifugally controlled CVT.

Also, there is no direct connection between the driver, control unit and gear ratio. That is, the driver can not actively select the speed ratio. Variations in transmission ratio have been determined so far by the mechanical configuration and characteristics of the CVT.

The present invention provides a CVT in which the transmission ratio of the CVT can be actively adjusted regardless of the centrifugal force.

The CVT according to the present invention having the features of claim 1 has the advantage that the transmission ratio of the CVT can be actively adjusted irrespective of the centrifugal force according to the present invention. This is achieved according to the invention by a V-pulley having an axially fixed cone pulley and an axially movable cone pulley; An axially slidable inner sleeve rotatably and rotatably connected to the axially movable cone pulley; And an axially slidable outer sleeve disposed coaxially with respect to the inner sleeve and rotationally coupled to the inner sleeve and rotationally separated from the inner sleeve, the outer sleeve including an accommodating peg And the receiving peg receives the end of a threaded spindle that rotates and translates together to adjust the axial position of the axially movable cone pulley so that the cone pulley rotates together with the outer sleeve, Which is designed to be coupled to the CVT.

By this measure, the transmission ratio of CVT can be actively changed and adjusted regardless of centrifugal force. The inner sleeve and the outer sleeve are rotatably coupled to each other and are rotatably coupled to each other. The outer sleeve is rotatably coupled to the outer sleeve through a threaded spindle, . By its engagement with the cone pulley movable in the axial direction, its position on the rotary shaft can be actively adjusted irrespective of the centrifugal force.

The dependent claims present preferred improvements of the present invention.

Preferably, the outer sleeve is formed substantially rotationally symmetrical with respect to the rotational axis of the V-pulley, and the receiving peg is disposed on the rotational axis.

In another preferred embodiment of the CVT according to the invention, the housing shell has at least one through-hole. The at least one through-hole is designed to receive and / or maintain on the receiving peg at least one element of the kick starter, i.e., the kick start actuating device, and in particular the double gear of the kick starter gear device, in the assembled state of the CVT do. By this measure, a normal kickstart mechanism can be incorporated in the CVT according to the invention in a particularly simple manner.

In another embodiment, the housing shell has a longitudinal shape comprising a first region of larger diameter and a second region of smaller diameter, in particular the first region is directed towards the inner sleeve, and for engagement with the inner sleeve And / or the second region comprises a housing end face with an accommodating peg. These measures enable a particularly compact construction because the longitudinal extent of the housing shell of the outer sleeve is likely to include a portion of the inner sleeve in the first region of the outer sleeve so that the overlap between the inner sleeve and the outer sleeve Because it takes a very small space.

The CVT according to the present invention may comprise a threaded spindle as a component, which is especially possible with a single piece of material. These measures reduce the cost of manufacturing and assembling the CVT, so additional production and assembly technical advantages are gained.

According to another embodiment of the CVT, the CVT comprises a regulating device for adjusting the axial position of the axially displaceable cone pulley, the regulating device being connected to the outer sleeve via a threaded spindle, A spindle nut engaged with the threaded spindle and rotatably driveable and translatably fixed, the adjustment device comprising a servo drive device, wherein during operation, the spindle nut, the threaded spindle and the receiving peg interact So that the rotation in the servo drive apparatus can be changed to the translational axial movement of the threaded spindle and the axially movable cone pulley. If the adjuster includes a servo drive, the active adjustment of the threaded spindle and the receiving peg to adjust the distance between the pulleys of the V-pulley can be made with high reliability in a controlled manner.

In another embodiment of the CVT according to the present invention, a torque support is provided which is designed and formed to support and rotate the outer sleeve together. By this measure, a particularly high level of functional reliability of the CVT according to the invention is given.

1 shows a schematic block diagram of a first embodiment of a CVT 1 according to the present invention.

In the drive shaft 11 or the crankshaft driven by the internal combustion engine 10, the inner sleeve 53 is mounted via the clamping sleeve 41 or other fixing means. An axially movable cone pulley 21, also referred to as a second cone pulley 21, is fixed to the inner sleeve 53 so as to rotate together. The inner sleeve 53 and the clamping sleeve 41 are coaxially arranged with respect to a common axis of symmetry X coinciding with the axis of rotation X of the cone pulley 21 and the common axis of rotation, . The inner sleeve 53 and the clamping sleeve 41 are particularly at least partly inserted one to the other and the inner sleeve 53 encircles the clamp sleeve 41. The inner sleeve 53 can slide along the clamping sleeve 41 to be displaced axially along the rotation axis X at that position.

The cone pulley 20 fixed in the axial direction is disposed in a state of being opposed to the cone pulley 21 movable in the axial direction and the cone pulley 20 fixed in the axial direction is fixed to the first cone pulley 20, And is rotatably engaged with the cone pulley 21 movable in the axial direction, but is separated to be translationally movable.

During operation, by rotation of the drive shaft or crankshaft 11 driven by the internal combustion engine 10, a device consisting of the first and second cone pulleys 20 and 21 of the V-pulley 2, The belt means 12, such as moving belts or the like, move in a specific radius of the drive wheels 20, 21 to drive the drive means 13, e.g. the corresponding second V-pulley, on the drive side, Particularly to drive shafts for driving wheels and the like.

A supporting member 4 is mounted on the clamping sleeve 41 to form a receiving space for the centrifugal element 3 in the form of one or more balls together with the back surface of the second cone pulley 21. However, the adjustment of the centrifugal force through the centrifugal element 3 of the type with respect to the support element 4 on the clamping sleeve 41 is not absolutely necessary and is a possible measure of the centrifugally controlled speed ratio setting of the CVT which has been used so far.

1 shows that the action according to the present invention can be combined with conventional centrifugal force control, but the action itself can also be preferably used.

The outer sleeve 54 is designed to be translationally coupled to the inner sleeve 53 and separated in a rotational manner. The rotary type separation is performed by the radial bearing 55. [ By this measure, the movement of the outer sleeve 54 is transmitted to the corresponding movement of the inner sleeve, and the inner sleeve and the outer sleeve 53, 54 can rotate relative to each other.

The outer sleeve 54 includes a housing shell 54a, a first housing end face 54b provided in the shell 54a away from the inner sleeve 53 and a second housing end face 54c toward the inner sleeve 53. [ And a radial bearing 55 is formed on the second housing end surface 54c.

The inner sleeve 53 and the outer sleeve 54 are formed rotationally symmetrical with respect to the axis of rotation X of the V-pulley 2 and the outer sleeve 54 and in particular its shell 54a define an inner sleeve 53 Concentrically or coaxially at least partially.

The first housing end face 54b is formed with an accommodating peg 8 projecting into the interior 54i of the outer sleeve 54. [ The receiving peg 8 includes a central hole 8a into which a threaded spindle 7 with an end 7a is inserted. The outer sleeve 54 and the threaded spindle 7 may be provided as separate elements and the end 7a of the spindle 7 inserted into the hole 8a of the peg 8 in this case may be a spindle pin or a bearing pin And is fixed to the outer sleeve 54 through the hole 8a. However, in the preferred embodiment, the device consisting of the outer sleeve 54 and the spindle 7 is formed in a material integral form.

In the embodiment of Fig. 1, the receiving peg 8, the hole 8a, the threaded spindle 7 and the end 7a thereof are coaxially and coaxially arranged with respect to the axis of rotation X, which is a symmetrical axis.

The threaded spindle 7 includes threads 7b on the outer circumferential surface and at least outside the region of its end 7a inserted into the hole 8a of the peg 8.

The thread 7b of the threaded spindle 7 is designed to engage with the adjustment of the adjusting device 5 or with the spindle nut of the driving gear 52 so that the spindle 7, Is driven in a controlled manner by a spindle nut, and in particular, is translated along the rotation axis (X).

Control can be made via the first and / or second measurement and / or control lines 6-1 and 6-2 by the control unit 6 and the second control line 6-2 can be made via the adjustment device 5 and the servo drive apparatus 50. [ The servo drive device 50 rotationally drives the adjustment gear 52 and the spindle nut therein through the drive shaft 51 and the spindle nut is rotatably supported by the thread 7b of the threaded spindle 7, , Here co-axially and along the axis of rotation (X). In this way, the threaded spindle 7 and the outer and inner sleeves 54, 53, which are translationally coupled with the threaded spindle, are located, for example on the one hand in position A or A 'and on the other hand B or B' The distance D between the cone pulleys 20 and 21 and thus the speed ratio to the belt 12 on the V-pulley 2 fluctuates.

An important aspect of the present invention is the provision of an inner sleeve 53 and an outer sleeve 54 and a shaft 55 for a first cone pulley 20 axially fixed via a coupling to a rotationally fixed spindle 7, Pulley 2 in the axial direction of the V-pulley 2, and therefore the controllability of the position of the second cone pulley 21 movable in the direction of the V- Lt; / RTI > In this case, control using the control unit 6 can be performed by a user of the vehicle, for example, a driver.

Conventional control systems for CVTs consist, for example, of a contact spring with a centrifugal force regulator on the primary side and a torque ramp on the secondary side.

According to the invention, the application of the additional force by the combination of actuators, namely the inner sleeve 53, the outer sleeve 54 and the threaded spindle 7, operated by the servo drive device 50, It is possible to change the CVT transmission ratio regardless of the contact force on the side.

From this, another advantage of the invention is obtained that the contact force on the secondary side can be reduced. Because of this, the only design criteria for spring and torque lamps is the realization of the CVT's slip-free operation, especially in the context of macro-slip.

As described above, the adjustment of the centrifugal force by the centrifugal element 3 supported by the support element 4 is not necessarily required. In this case, the inner sleeve 53 should be fixed to the movable pulley 20.

However, when the centrifugal force is adjusted, the inner sleeve 53, which may be referred to as a sliding bushing, can be firmly connected to the movable pulley 21 by three fingers, for example, press fitting, caulking or the like. The inner sleeve 53 with the fixed movable pulley 21 slides on the clamping sleeve 41. The stationary pulley 20, the clamping sleeve 41 and the support member 4 are rigidly connected to the crankshaft 11 via a kick starter nut 66.

Another issue of the kick starter nut 66 is to introduce a rotary motion into the crankshaft 11 from the kickstart gear assembly 62 of the kickstart device 60 to perform starterless engine startup.

The three fingers of the inner sleeve or sliding bushing 53 project through the recess of the stationary pulley 20. In particular, the flange ring 70 as shown in Figure 4 is pressed against the stop ring with a locking nut and is rigidly connected to the inner sleeve 53.

An electric gear motor as the servo drive device (50) rotates the spindle system. This rotational movement is converted into translational motion by the spindle / spindle nut system in the gear 52 and is introduced into the outer sleeve 54, which may have a longitudinal shape.

The other spindle end (7a) is rigidly connected to the outer sleeve (54). An adjustment movement is introduced into the inner sleeve 53 by the bearing 55, in particular by the radial bearing 55, in order to separate the rotary motion and the linear motion in the outer sleeve 54, ).

The distance between the two pulleys 20 and 21 varies so that the belt 12 moving between the pulleys 20 and 21 has a diameter that is predetermined by the pulleys 20 and 21 and the distance therebetween, .

The gear drive 62 of the kick starter 60 is engaged by the first through hole or the first through-hole 57 in the outer sleeve 54, which may be referred to as the first recess or first recess. The kick starter double gear 67 is mounted directly to the receiving peg 8 of the outer sleeve 54. The rotation of the kickstarter drive 62 is transmitted to the kickstarter dual gear 67 through the drive gear 64. [ The helical gear causes movement of the gear 67 in the kickstarter 2 until the crown gear of the kickstart dual gear 67 engages with the crown gear of the kickstart nut 66. [

When the internal combustion engine 10 is automatically moved, the first kickstart gear 67 is easily braked by the brake spring 65. The tooth shape of the crown gear and the reverse rotation of the kick starter driver move the kick starter double gear 67 back to the starting position. That is, disengaged with the kick starter nut 66.

The particular geometry of the outer sleeve 54 in the form of a bell and the complementary or cooperative shape of the housing 14 prevent accidental rotation due to friction in the bearing. As a result, collision between the through-holes 57, 58 in the species and the teeth of the kickstarter drive wheel 64 is prevented. This also makes it possible or easy to assemble in the correct position.

2 is a schematic, partially cut away side view of another embodiment of a CVT 1 according to the present invention.

In addition to the elements shown in Fig. 1, the insertion of the threaded spindle 7 into the hole 8a of the receiving peg 8 is clearly indicated in Fig. 2 using a spindle pin or an end portion 7a as a bearing pin Respectively.

2 also shows that the housing shell 54a of the outer sleeve 54 includes a first through-hole 57, which may be referred to as a first window or first recess, and a portion of the kick starter mechanism 60, Is inserted into the outer sleeve 54 formed as a sieve so that a first kickstart gear 67 designed, for example, as a double gear 67, a second kickstart gear (here in the form of a kickstart nut 66) 66) and engage with it.

As the first kickstart gear 67, the double gear is supported on the outer peripheral surface of the receiving peg 8. By moving axially along the axis of rotation X, the first kickstart gear 67 can engage the kickstart nut 66, so that the kickstart process is performed during operation of the kickstart device 60.

The housing shell 54a of the outer sleeve 54 also includes a second through-hole 58, which may be referred to as a second window or second recess, and a brake spring 65 for the kickstart device 60 And is guided through the through-hole 58 into the inside 54i of the outer sleeve 54. [

Figure 2 shows that the housing shell 54a includes a first region 54-1 having a larger diameter d1 and a second region 54-2 having a smaller diameter d2, A radial bearing 55 is formed in the region 54-1 and an accommodating peg 8 is formed in the second region 54-2.

Figures 3 and 4 illustrate the embodiment of Figure 2 with two different positions of the first and second pulleys 20, 21 with respect to the axial distance, in Figure 3, between the pulleys 20, 21 And is smaller in the state according to Fig.

The sequence of Figures 5 to 9 shows the outer sleeve 54 in detail, in particular in partial perspective, in an embodiment of the invention, and Figure 8 is a side sectional view.

The outer sleeve 54 of this embodiment includes a housing shell 54a having a first region or section 54-1 of larger diameter d1 and a second region or section 54-2 of smaller diameter d2, ). The second housing section 54-2 includes a first housing end face 54b that substantially closes the opening of the housing shell 54a. An accommodating peg 8 is formed from the housing end face 54b towards the interior 54i and the receiving peg 8 is provided to receive a threaded spindle 7 with a spindle pin or bearing pin at the end 7a And includes a hole 8a accessible from the outside.

The housing shell 54a includes a first window as a first through hole 57 for engagement with the kickstarter mechanism 60. In addition, a second window is provided as a second through-hole 58 which is used for receiving the brake spring 65.

In Fig. 5, the bearing pin is not yet assembled at the end portion 7a of the screw spindle 7.

6 to 9, the bearing pin on the end 7a and the threaded spindle 7 with the thread 7b are already introduced into the hole 8a of the receiving peg 8 and fastened thereto.

7 to 9, the elements of the kickstart apparatus 60 are further illustrated. The kickstart gear 62 includes a first kickstart gear in the form of a double gear 67 which is coupled to the drive gear 64 of the kickstart gear 62 of the kickstart device 60 And is engaged with the outside. The double gear 67 is mounted on the receiving peg 8.

Figs. 10-12 illustrate perspective views showing the housing 14b and the transmission housing 14 in the transmission housing 14 for receiving the outer sleeve 54. Fig.

The outer sleeve (54) Has a shape complementary to the shape of the receiving portion 14b of the transmission housing 14 on the side surface 54b, particularly in cross section. In particular, the first housing end face 54b includes a recess 54d along with a hole 8a for the receiving peg 8 on the outer circumferential surface, and the recess 54d allows the outer peripheral face of the first housing end face 54b It is no longer rotationally symmetric. That is, it is not a strict circle when viewed in cross section. As a result, a torque assisting body 9 and an assembling assistant means for assembling at an accurate position are realized.

The housing portion 14b in the housing 14 has a protruding portion 14c which may be a nose or a shoulder portion on the inner circumferential surface so that when the housing portion 14b is fitted into the first housing end surface 54b, Twist-free support of the outer sleeve 54 to the housing 14 is achieved. That is, the shape fitting connection is formed through the recesses 54d and the projecting portions 14c. In the assembled state, the threaded spindle 7 engages with the drive device in the transmission housing 14 through the clearance hole 14d.
