Description of the invention: [Technical field to which the invention pertains] The invention relates to an automatic motorcycle or a snowmobile and a rotary action one-way clutch, and as a one-way when the number of rotation exceeds a predetermined value clutch. [Prior Art] Generally, a one-way clutch includes inner and outer rings that rotate relative to each other and a design thereof so that rotational torque is transmitted only in one direction, whereby a rim or roller card for transmitting torque between the inner and outer rings will be used And a cam surface is provided on the surface of the outer ring or the inner ring, and an idling system is implemented in a reverse direction. In such a one-way clutch, it provides a one-way clutch in which the roller is disposed in a recess (recess) provided by the inner and outer rings, and the rotation depends on the direction of rotation, and the card is wedged by the roller and the pocket The wedge action is locked. For example, Japanese Patent Laid-Open Publication No. 53_8-19 (1978) discloses an arrangement in which a roller is disposed in a recess provided by an outer ring, and when the outer ring rotates in a forward direction, the roller is locked in the recess by a wedge action Thereby locking the rotation of the outer ring relative to an inner ring. Further, in the prior art, a 52-100045 (1977) chrome-plated configuration, wherein a roller and an auxiliary roller are disposed between an outer ring and an input coupling so that the number of rotations exceeds a predetermined value. The auxiliary roller is driven by the centrifugal force to press the roller. In this case, when a rotation is generated by the driving force in a predetermined direction, the roller can be locked by a wedge action, thereby achieving a one-way clutch function. The configuration disclosed in the above-mentioned Japanese Patent Application Laid-Open Publication No. 53-8-19 discloses a general or ordinary one-way clutch using the roller, and the locking of this configuration is not achieved in accordance with the number of rotations. Further, the above-mentioned Japanese Patent Application Laid-Open Publication No. No. discloses that the locking of the configuration is achieved based on the number of rotations. However, since it is determined that the extended hole of the auxiliary roller is different from the member of the outer ring, it is difficult to obtain the dimensional accuracy required for the device, and the number of parts is increased. Furthermore, since it is not desirable for the roller to be locked by the elongated hole, it is desirable to provide a plate or a fixing and carrying member for driving the roller, and since the need for a mounting space for the elastic cyanine, the reduction in the diameter of the device will be limited. . Further, insofar as the coil spring is used as the material for biasing the roller, it is difficult to set the elastic constant of the coil spring to a small value to conform to a limited space, and the coil spring is more expensive than the folded spring.

For the purpose of the present invention, the present invention provides a one-way clutch of a rotary action type to form two outer rings of an inner circumferential cylindrical surface, a flange surface member, and a bias between the outer ring and the inner ring. The rotation torque of the transmission wheel is biased against the mm mouse + ancient and a centrifugal force to resist the piece, and one of the heavy-duty structures including the direction is provided between the material ring and the _ partial (four) 贳 ^ clothing, and the dragon has a guide?丨 91024-951130.doc 1279498 The weight component movement surface of the component movement. Furthermore, the present invention provides a rotary action type one-way clutch comprising: an inner circumferential cylindrical surface outer ring, a flange on which the flange surface is formed, and a transmission between the % and the inner % a torque rolling member, a biasing spring biasing the rolling member, and a hunting centrifugal force resisting the biasing spring biasing force to drive the rolling member "cutting the weight of the summer component, and i The continuous inner ring has a recess 4 on its outer peripheral surface to partially receive the weight member. Furthermore, the present invention provides a one-way clutch that is erected and suspected to rotate, including an inner circumferential cylindrical surface, a flange for forming a flange surface thereon, and an outer ring and The rolling member of the transmission torque between the inner loops, the biasing of the rolling member, the re-drying bias, and the hunting centrifugal force resist the biasing force to drive the rolling a weight member of the rotating member facing the engaging direction, and a roller member including the rolling member, the weight of the eight-mile member and the biasing spring, and a side plate for restricting the axial movement of the spring and the spring Between the outer raft and the inner ring, and the wind cargo has an axial through hole in the q S or the side plate. Furthermore, the present invention provides a one-way clutch for the wire 4 < 札, 疋 动作 action, comprising a /, an inner circumferential cylindrical surface, an i #, ^ ^. a flange surface formed thereon In the outer ring and the inner ring, the biasing member t of the rolling member: the rolling member of the reading moment, and the biasing force drives the rolling mechanism: the centrifugal force against the card 2 resists the partial (four) spring bias The weight member is in line contact with the weight member ' of the inner ring > direction and the garment/port thereof. According to the invention as described above, there is a month b 4 to the following effects. Because the biasing spring is pretty good, the M is pressed against the surface of the cam member, and the star-shaped 卞 方向 direction is biased toward the weight member, and the centrifugal force is used to resist the 91024-951130.doc 1279498 When the biasing force of the biasing spring drives the roller member to face the engagement direction with respect to the cam surface, a rotary action type one-way clutch, wherein the number of parts can be reduced and cheap, and the spring constant can be set to a small value and accurate in size. The degree can be easily obtained, and the weight member is not locked and the design can be achieved in a limited space. Is further the invention can achieve the following special effects. According to the present invention, the weight member can achieve a smooth operation. Furthermore, manufacturing costs can be reduced. For example, the pocket is provided in the inner ring and t, although the portion corresponding to the far pocket must be removed by polishing, cutting and/or wire cutting, since the portion corresponding to the pocket has a large volume, the work The time becomes large and the variation due to the heat treatment can occur. Furthermore, it is possible to lower the range of cam surfaces that require high precision. Furthermore, it can surround a large weight component. It can strengthen the lubrication ability of the one-way clutch n. Moreover, the work is easy to achieve and the yield is increased. According to the configuration of the present invention, the excessive movement of the roller in a non-operating state is suppressed. This work can be easily achieved and the yield increased. The balance of the strength of the cage can be achieved. In this case, the term "rotary action" means that the one-way clutch function can be correctly achieved over a range of rotations exceeding the predetermined number of revolutions. However, the early clutch function can be rotated at a low speed range and/or less than the predetermined range. The rotation range of the number of rotations is achieved. Further, the predetermined number of rotations is determined according to the mass of the weight member, the distance between the weight member and the center of the inner ring, and the inclination angle of the surface of the weight member. The present invention will be fully explained with reference to the accompanying drawings in the drawings. In the drawings, the same reference numerals represent the same elements. (First Embodiment) First, the first embodiment of the present invention will be described. Fig. 1 is a front view of the rotary action type one-way clutch 30 according to the first embodiment, and Fig. 2 is a schematic view of the recessed portion when viewed from the outer side of the first embodiment. A roller 37 constituting one-way clutch portion A weight member 38 and a folding spring 35 are covered and fixed in one of the window portions 43 provided in the cage 32 (see Figures 2 and 4). A substantially annular cage 32 disposed between the outer ring 3 and the inner ring 2 is a cage body and a substantially annular support plate 34 is provided at the axial end of the cage 32. The support plate 34 is fixed by a cage coupling portion 33. The cage 32 is disposed at each of the window portions 43 equidistantly disposed in the circumferential direction of the cage 32, and includes a folding spring 35 biasing the roller 37 from the outer ring 3 side, and the outer ring 3 and the inner ring 2 A torque roller 37 is transmitted between the weight member 38 that acts on the roller 37 to urge the roller 37 toward the engaging direction. When the weight member 38 is not applied to the roller, a portion of the weight member 38 is surrounded. a recess 31 provided in the outer peripheral surface of the inner ring 2. The arcuate radius of the bottom surface forming the recess 31 is larger than the radius of the weight member 38 and the weight member 38 is in contact with the recess 31 in a straight line. That is, the weight member is locked by the recess for smooth movement, thereby enhancing the operation of the device. Each of the cages 32 has a deep concave portion 36 of a flat u-shaped radial segment, and the folding magazine 35 is used to bias the The opposite end of the roller 37 is attached to and fixed by the recess 36 Referring to Fig. 4), 91024-951130.doc -10- 1279498 It can be seen from Fig. 2 that the window portion 43 of the cage 32 is formed by drilling the cage 32 in an axial direction while maintaining a wall portion. The axially open end of the window 43 is closed by the support plate 34. Therefore, the folding spring 35, the roller 37 and the weight member 38 included in the window portion 43 are axially fixed by the wall of the cage 32 and the support plate 34, and The outer ring 3 and the inner ring 2 are radially fixed so that these elements do not fall out of the window portion 43. Fig. 3 is an axial sectional view of the rotary action type one-way clutch 3〇. It can be seen that the support plate 34 is The cage coupling portion 33 is fixed to the cage 32. Further, it can be seen that the roller 37 has a small gap between the wall portion of the cage 32 and the support plate 34 and is supported in an axial direction. Next, the operation of the rotary action one-way clutch 3 根据 according to the first embodiment will be explained with reference to Figs. 4 is a view showing a roller and a weight member in a non-rotation state and a low-speed rotation in the first embodiment, and FIG. 5 is a view showing an operation state (engagement state) in the first embodiment.

When the weight member 38 is subjected to a centrifugal force, the weight member is moved toward the outer diameter side along the surface of the member member to contact and drive 37, thereby moving the roller (4) upward to the engaged position. Furthermore, the I 91024-951130.doc -11 - 1279498 wheel 37 is provided on the outer diameter side of the roller locking position (rolling configuration block locking position) 42 facing the weight member 38. In the illustrated embodiment, although the weight member moving surface 4〇 and the roller locking portion 42 are continuously provided, it is not necessarily continuous. A recess 31 for partially surrounding the weight member 38 is provided in the outer peripheral surface of the inner ring 2 at a position opposite to the weight member operating surface 40 and the cage lock portion 42 of the cage 32, and a torque as the roller 37 The cam surface 47 of the transfer surface is formed adjacent to the recess 31. In the illustrated embodiment, although the recess and cam surface 47 are continuously provided, they need not be continuous. The reason why the recess 31 partially houses the weight member 38 is to minimize the operating range of the weight member 38. As shown in FIG. 4, in a non-rotating state and during a low-speed rotation (range), the weight member 38 is located on the inner diameter side of the recess 31, and the roller 37 is driven by the folding spring 3 5 to The roller lock portion 42 is ratned. Thereafter, the inner ring 2 will rotate. When the inner ring rotation speed reaches a speed higher than the predetermined number of rotations, the weight member 38 subjected to the centrifugal force moves toward the outer diameter side, thereby moving the roller 37 to the engagement position of the cam surface 47. In this state, the inner ring 2 rotates relative to the outer ring 3 in a counterclockwise direction and a leading manner. This operational state is shown in Figure 5. (Second Embodiment) Next, a second embodiment of the present invention will be explained with reference to Figs. 6 to 丨3. In the second embodiment, the positional relationship between the weight member 38, the roller 37 and the folding spring 35 and the operation of these elements are substantially the same as those of the first embodiment. In the second embodiment, a cage shape has a large difference from the first embodiment of the phase 91024-951130.doc -12-1279498. Now, the cage used in the second embodiment will be explained with reference to Figs. Figure 10 is a development view of a first plate 60 of the cage 50 according to the second embodiment, and Figure 11 is an exploded view of the second plate 70 of the cage 50 according to the second embodiment. In the second embodiment The cage 50 is formed by a plate-shaped steel plate to form the first and second plates. Figure 10 is an expanded view of a first panel. The first plate 6 includes a plurality of protrusions extending radially from a generally annular body portion 66. Each of the projections is a first column portion 51 in which a folding magazine 35 connecting hole 62 is formed. A plurality of holes 67 associated with the cage pocket or window portion and the exterior are formed in the outer periphery of the body portion 66. Metal powder generated in the clutch and foreign matter or lubricant dust can be discharged to the outside through the hole 67. The hole can be formed in a side panel (not disclosed) instead of the cage. Furthermore, the number of holes can be arbitrarily selected and the majority of the holes are not necessarily provided. The pinhole 64 for connection to the second plate 7A is formed in the body portion 66. Further, the two engaging jaws 65 for fixing the cage 5 to the inner ring 2 are provided on the inner diameter side of the body portion 66. The protruding portion, the clamping hole M and the engaging tongue are preferably disposed equidistantly along the circumferential direction. The engaging tongue 65 is mounted in the recess 54 of the inner ring 2 to fix the entire cage to the inner ring 2. Figure 11 is a developed view of a second plate 70. The second plate 7A includes a plurality of protrusions extending radially from a generally annular body portion 75. Each of the protrusions includes a first portion 72 and a gap-filling projection 71.

The projection and the engaging tongue 74 are preferably equidistantly arranged along a circumferential direction. The cage of the second embodiment 5〇 (refer to FIGS. 6 and 7) is obtained by bending the first plate 60 and the second plate 70 to a desired shape, and then joining the two plates together. Next, the second embodiment is rotated. The one-way clutch 8 will be fully explained with reference to Figures 6 to U. Figure 6 is a front view of the rotary action single = clutch 80 according to the second embodiment. 2 is an axial cross-sectional view of the rotary-acting one-way clutch 80. Further, FIG. 8 is a view showing the pattern of the roller and the weight member of the second embodiment in a non-rotating state and during a low-speed rotation, and FIG. A drawing in which the roller and the weight member in the second embodiment are in a state of being engaged (engaged state) is disclosed. In FIG. 6, the cam surface provided on the outer circumferential surface of the inner ring 2 is substantially the same as the first embodiment. The second embodiment is different from the first embodiment in that the operating surface of the weight member 38 is formed in the protrusion provided on the first or second board constituting the cage %. The caulking protrusions 71 of the two plates 70 are formed into the clamping holes 64 of the first plate to form the interstitial, and the cages 5 are formed through the coupling portion 53 to form the protrusions of the crucibles (four) two plates 70. The outer ring 3 is positioned. The inner peripheral side, thereby forming the weight member action surface 52, wherein the weight member action surface has a predetermined inclination with respect to the radial direction. Fig. 7 is an axial sectional view of Fig. 6. It can be seen that the cage brother The first plate 60 and the second plate 7 are included Next, the operation of the one-way clutch 80 of the second embodiment will be explained with reference to Figs. 8 and 9. The basic operation is the same as that of the first embodiment. As shown in Fig. 8, at the 91024-951130.doc • 14-1279498 During the rotation state and during the low speed rotation, the weight member 38 is located on the inner diameter side of the concave portion 31 and the roller 37 is urged toward the non-engagement direction by the folding spring 35. Subsequently, the inner ring 2 is rotated. When the inner ring rotation speed reaches a speed higher than the predetermined number of rotations, the weight member 38 subjected to the centrifugal force moves toward the outer diameter side along the weight member operation surface 52, thereby moving the roller 37 to the coupling position of the cam surface 47. In this state, when the inner ring 2 is rotated in a counterclockwise direction relative to the outer ring 3 in the aforementioned manner, the torque will be transmitted. This operational status is shown in Figure 9. The relationship between the cage 50 and the folding spring 35 is as follows: Fig. 12 is a schematic view showing the portion of the recess from the side of the outer diameter of the second embodiment. Figure 13 is a front elevational view of the folding spring attachment portion according to the second embodiment. As shown in Fig. 12, the folding spring 35 has a distal end that drives the roller seating portion 58, and the folded proximal end attachment portion (four). The folding type slab 35 utilizes the attachment portion 57 to tighten the first column portion. Further, the folding spring 35 is further stably fixed by engaging the attachment portion with the tongue 56 provided by the hole _. The attachment state of the attachment portion 57 of the folding spring 35 is such that the tongue 56 provided by the phase attachment portion 57 of the folding spring 35 is mounted in the hole 62 of the scorpion-plate 60. According to the second cost, it can be reduced. ^ Incidentally, although it is considered that the heavy-duty lining member can be made of steel 'copper, steel, aluminum, or synthetic resin, η 7^ 疋 in an example, the weight is made of a specific gravity such as steel material. , /,,, The centrifugal force acting on the area of the early zone is 91024-951130.doc -15- 1279498 becomes bigger 'even when the $+ person is loaded. ^ Close to the day, during this low-speed rotation can still achieve -, for the weight of 1 member 38 diameter can be reduced. ‘In the above-described example only, although the cylindrical roller is used as an example of a rolling member; ^u phase VIII ^ ^ θ to explain that a sphere can be used as a rolling member. Furthermore, the re-reading member may be a sphere instead of the mixing of the cylindrical rolling member and the weight member, so that one of the components may be a roller and the other may be a sphere. Furthermore, in the above embodiment, although a plurality of pockets are provided along the circumferential direction, the number of phase holes can vary with the required torque capacity and the like, and eight recesses, for example, four or six recesses can be provided. hole. However, regardless of the number of recesses, the recesses are preferably arranged equidistantly along the circumferential direction. In the first and second embodiments, although the example in which the diameter of the roller and the weight member are substantially the same is explained, it is not necessary that the diameter is the same and the diameter can be used depending on the state of use (for example, in the action state) It is free to set.
