  The return spring 34 urges the parking pole 32 so that the claw portion 32 </ b> A swings downward about the parking pole shaft 33. Accordingly, the parking pole 32 is urged by the return spring 34 so as to swing from the meshing position to the release position.

  In FIG. 7, a parking rod 35 is installed below the bearing support portion 12. In FIG. 10, the parking rod 35 has a straight side 35A and a bent portion 35B. The straight side 35A extends in the same direction as the axial direction of the input shaft 14 and the counter shaft 16, and the bending portion 35B is formed in an L shape so as to be bent upward from the straight side 35A.

  The parking rod 35 is movable along the axial direction of the input shaft 14 and the counter shaft 16. It is installed in the axial direction of the input shaft 14. The axial direction of the parking rod 35 is the direction in which the straight side 35A extends (the left-right direction, the depth direction of the left case 2).

  The cam member 43 is attached to the tip of the straight side 35A, and the cam member 43 is movable along the axial direction of the straight side 35A at the outer peripheral portion of the straight side 35A.

  A stopper portion 35a is formed on the bent portion 35B side of the straight side 35A, and a cam spring 44 is provided between the cam member 43 and the stopper portion 35a. A stopper portion 35b is formed at the tip of the straight side 35A.

  The cam spring 44 biases the cam member 43 until the cam member 43 comes into contact with the stopper portion 35b, and the cam member 43 is prevented from coming out of the parking rod 35 by coming into contact with the stopper portion 35b. .

  The cam member 43 has a tapered cam surface 43a in the direction in which the straight side 35A extends from the stopper portion 35a toward the stopper portion 35b.

  The bending portion 35 B is attached to the manual plate 40. The manual plate 40 is attached to the upper end 37a of the manual shaft 37 on the lower end 37b side (see FIG. 2).

  The manual shaft 37 is installed on the side opposite to the counter shaft 16 with respect to the input shaft 14 and on the front vertical wall 8 side with respect to the bearing support portion 12. They extend in the height direction of the left case 2 at right angles. The manual shaft 37 is disposed within the range of the bearing support 12 in the axial direction of the input shaft 14, that is, within the projecting range of the bearing support 12.

  In FIG. 1, the upper end portion 37 a of the manual shaft 37 is rotatably supported by the upper wall 9 of the left case 2. The lower end portion 37b of the manual shaft 37 penetrates the bottom wall 10 of the left case 2 and protrudes downward from the bottom wall 10, and the bottom wall 10 is rotatably supported.

  One end of a parking cable (not shown) is connected to the lower end 37b of the manual shaft 37 via a lever (not shown). The other end of the parking cable is connected to a selector lever (not shown) disposed in the vehicle cabin and operated by the driver.

  The selector lever is moved by the driver to any position between the parking range and the non-parking range. At this time, the manual shaft 37 rotates, and the manual plate 40 swings as the manual shaft 37 rotates, thereby moving the parking rod 35 in the axial direction.

  In FIG. 6, a support member 36 is installed below the bearing support portion 12. The support member 36 is disposed below the parking pole 32 and is U-shaped when viewed from the axial direction of the input shaft 14.

An extending cylindrical surface 36b is formed.

  In the parking lock mechanism 31, when the shift lever is operated to the parking range, the manual shaft 37 rotates in one direction, and the manual plate 40 is swung in one direction as the manual shaft 37 rotates.

  At this time, the parking rod 35 moves to the parking pole 32 side, and the cam member 43 rides on the cylindrical surface 36b from the conical surface 36a of the support member 36 as shown in FIG. When the cam member 43 rides on the cylindrical surface 36b, the cam member 43 pushes up the parking pole 32 upward.

  At this time, the parking pole 32 is swung counterclockwise in FIG. 2 about the parking pole shaft 33 against the urging force of the return spring 34.

  As a result, the pawl portion 32A of the parking pole 32 is fitted to the tooth portion 18A of the parking gear 18, and the rotation of the parking gear 18 is restricted. In this state, the cam member 43 is positioned between the parking pole 32 and the support member 36, so that the engagement between the claw portion 32A and the tooth portion 18A is not released.

  When the cam member 43 pushes the parking pole 32 upward, the cam spring 44 is compressed. At this time, the restoring force of the cam spring 44 exceeds the frictional force between the cam member 43 and the parking pole 32 and the restoring force of the return spring 34.

  Thus, the cam member 43 can be reliably inserted between the support member 36 and the parking pole 32, and the parking pole 32 can be reliably rocked so that the claw portion 32A moves to the parking gear 18 side.

  In the parking lock mechanism 31, when the shift lever is operated to the non-parking range, the manual shaft 37 rotates in the other direction, and the manual plate 40 is swung in the other direction as the manual shaft 37 rotates.

  At this time, the parking rod 35 moves to the far side away from the parking pole 32, and the cam member 43 moves from the cylindrical surface 36b of the support member 36 to the conical surface 36a.

  At this time, the parking pole 32 is urged by the return spring 34 and swings around the parking pole shaft 33 in the clockwise direction of FIG.

  Thereby, the claw portion 32A of the parking pole 32 is separated from the tooth portion 18A of the parking gear 18, and the fitting between the claw portion 32A and the tooth portion 18A is released. As a result, the rotation of the parking gear 18 is not restricted.

  As described above, the manual plate 40 according to the present embodiment converts the rotation of the manual shaft 37 into the movement of the parking pole 32 in the axial direction by swinging around the manual shaft 37.

  1 and 2, a detent plate 38 is attached to the upper end portion 37a of the manual shaft 37, and the detent plate 38 is swung as the manual shaft 37 rotates. Fitting grooves 38 </ b> A and 38 </ b> B are formed on the outer periphery of the detent plate 38.

It is in the meshing position which meshes with the portion 18A.

  On the other hand, in the state where the manual shaft 37 is rotated by the driver's shift operation and the detent plate 38 swings and the roller member 39A is fitted in the fitting groove 38B, the pawl portion 32A of the parking pole 32 is moved to the parking gear 18. In the release position deviated from the teeth 18A.

  The detent plate 38 and the detent spring 39 constitute a detent mechanism, and the driver at the time of the shift operation is moved by moving the roller member 39A between the fitting groove 38A and the fitting groove 38B at the time of the driver's shift operation. Gives the user the feeling of switching (so-called click feeling).

  Further, the detent plate 38 swings around the manual shaft 37 as a swing center, and the roller member 39A is positioned between the fitting groove 38A and the fitting groove 38B, thereby positioning the manual shaft 37 in the rotational direction.

  According to the driving device 1 of the present embodiment, the intermediate recess 27 that bulges outward from the left vertical wall 5 in the axial direction of the input shaft 14 within the range in which the manual shaft 37 extends on the left vertical wall 5 of the left case 2. An upper recess 28 and a lower recess 29 are formed.

  The parking rod 35 is installed in the axial direction of the input shaft 14 so as to move along the axial direction of the input shaft 14. The input shaft 14 and the input gear 15 are disposed between the detent plate 38 and the manual plate 40 in the axial direction of the manual shaft 37, and the parking rod 35, the manual shaft 37, a part of the detent plate 38 and the manual plate 40. Is accommodated in any of the intermediate recess 27, the upper recess 28 and the lower recess 29.

  This can prevent the manual plate 40 and the detent plate 38 from interfering with the input shaft 14 and the input gear 15 when the manual shaft 37 rotates.

  For this reason, the parking rod 35, the manual shaft 37, the detent plate 38, and the manual plate 40 are installed using the space in the axial direction of the input shaft 14, that is, the intermediate recess 27, the upper recess 28, and the lower recess 29. Can.

  Therefore, the manual shaft 37 can be brought close to the input shaft 14 and the input gear 15 between the manual plate 40 and the detent plate 38.

  As a result, the parking lock mechanism 31 can be efficiently installed inside the left case 2 and the enlargement of the left case 2 can be suppressed.

  Further, since the lower recess 29 bulging outward from the left vertical wall 5 in the axial direction of the input shaft 14 is provided in the left case 2, the rigidity of the left case 2 can be increased by the lower recess 29. And by accommodating the parking rod 35 and the manual plate 40 in the lower concave portion 29 having high rigidity, the behavior of the parking rod 35 and the manual shaft 37 can be stabilized.

  Specifically, the reaction force F1 (see FIG. 2) acts in a direction orthogonal to the virtual plane L1 from the input gear 15 via the input shaft 14 due to the meshing between the input gear 15 and the counter gear 17 when the vehicle travels. In this case, deformation or vibration of the lower recess 29 can be suppressed.

  For this reason, the behavior of the manual plate 40 accommodated in the lower recess 29 can be stabilized. Moreover, since it can suppress that the lower side recessed part 29 deform | transforms and vibrates, the manual plate 40 can be installed close to the wall surface of the lower side recessed part 29, and the space which accommodates the parking rod 35 and the manual plate 40 can be provided. It can be minimized. As a result, the left case 2 can be more effectively downsized.

  Further, according to the driving device 1 of the present embodiment, the intermediate concave portion 27 accommodates the intermediate portion 37 c in the axial direction of the manual shaft 37, and the upper concave portion 28 is located outside the intermediate concave portion 27 in the axial direction of the input shaft 14. Since it bulges in the direction, the rigidity of the upper concave portion 28 can be increased.

  Thereby, when the vehicle travels, the input gear 15 and the counter gear 17 mesh with each other, so that the reaction force F2 (in the direction orthogonal to the imaginary plane L1 from the input gear 15 via the input shaft 14) is opposite to the reaction force F1 ( When the action (see FIG. 2) acts, the upper recess 28 can be prevented from being deformed or vibrated.

  Furthermore, since a part of the detent plate 38 is accommodated in the rigid upper recess 28, the behavior of the detent plate 38 can be stabilized. Further, since the upper recess 28 can be prevented from being deformed or vibrated, the space for accommodating the detent plate 38 can be minimized, and the left case 2 can be reduced in size accordingly.

  Although a part of the detent plate 38 is accommodated in the upper recess 28, the entire detent plate 38 may be accommodated. In this case, the upper recess 28 may be expanded outward in the axial direction of the input shaft 1 so that the entire detent plate 38 can be accommodated.

  Further, the lower concave portion 29 of the present embodiment is connected to the first concave portion 29A extending in the swinging direction of the manual plate 40 and the first concave portion 29A and extends in the swinging direction of the manual plate 40. And the second recess 29B having a larger curvature in the swing direction of the manual plate 40 than the recess 29A, and the manual plate 40 swings in a range where the second recess 29B is formed.

  Thereby, the bulging amount of the lower concave portion 29 can be reduced by the amount provided for the first concave portion 29A. In other words, it suffices to expand the lower recess 29 by a range in which the manual plate 40 swings, and the enlargement of the left case 2 can be effectively suppressed.

  Further, according to the driving device 1 of the present embodiment, the stopper ribs 28A, 28B are provided on the inner wall surface of the upper recess 28, and the stopper ribs 28A, 28B are located in the same plane as the detent plate 38. As the manual shaft 37 rotates, the detent plate 38 comes into contact or non-contact.

  As a result, when the detent plate 38 swings between the meshing position and the release position, the detent plate 38 swings beyond the meshing position and the release position by contacting the stopper ribs 28A and 28B. Can be regulated.

  For this reason, the swing of the detent plate 38 can be easily regulated by the simple configuration in which the stopper ribs 28A and 28B are processed on the inner wall surface of the upper concave portion 28, and parts for regulating the swing of the detent plate 38 are the left case 2 It can be unnecessary to provide it separately.

  As a result, it is not necessary to secure a space for installing a new part for restricting the swing of the detent plate 38 inside the left case 2, and the left case 2 can be reduced in size. 1 manufacturing cost can be reduced.

  In addition, by providing the stopper ribs 28A and 28B on the inner wall surface of the upper recess 28, the rigidity of the upper recess 28 can be increased, and the upper recess 28 can be prevented from vibrating or deforming due to an external force. Therefore, the behavior of the detent plate 38 can be stabilized.

  Further, according to the driving apparatus 1 of the present embodiment, the parking rod 35 is installed on the input shaft 14 side with respect to the manual shaft 37, and the support member 36 includes the first retainer 41 and the second retainer 42. It is connected to the left case 2 through.

  Thus, the support member 36 can be fixed to the left case 2 without using the front vertical wall 8 and the bottom wall 10 of the left case 2. Therefore, it is unnecessary to provide the left case 2 with the structure for attaching the support member 36, and the structure of the left case 2 can be simplified accordingly.

  Furthermore, since the parking pole shaft 33 is supported by the first retainer 41 and the boss portion 51 formed on the left case 2, the parking pole shaft 33 is utilized by using the first retainer 41 and the second retainer 42. Can be made unnecessary.

  For this reason, the 2nd retainer 42 can be reduced in size and the parking lock mechanism 31 can be reduced in size.

  Further, according to the driving apparatus 1 of the present embodiment, the counter gear 17 having a diameter larger than that of the input gear 15 is provided on the opposite side of the input gear 15 from the manual shaft 37. A final driven gear 22 having a diameter larger than that of the counter gear 17 is provided on the side opposite to the gear 15.

  The rotation center axis O1 of the input gear 15, the rotation center axis O2 of the counter gear 17 and the rotation center axis O3 of the final driven gear 22 are located on the same virtual plane L1, and the parking pole 32 is the input gear 15 and It is installed between the counter gear 17 and the bottom wall 10.

  The parking pole shaft 33 is installed on the final driven gear 22 side with respect to the input gear 15, and the parking pole 32 extends from the parking pole shaft 33 to the manual shaft 37 side.

  Thus, the parking pole 32 can be installed in a wide space between the input gear 15 and the counter gear 17 and the bottom wall 10, and the swing range of the parking pole 32 can be expanded. Therefore, the parking lock mechanism 31 can be installed more efficiently inside the left case 2, and the enlargement of the left case 2 can be more effectively suppressed.

  The parking pole 32 of the present embodiment is swung by the parking pole shaft 33 provided at one end of the parking pole 32. As a result, the swing range of the parking pole shaft 33 can be made smaller than in the case where the parking pole shaft is provided at the central portion in the extending direction of the parking pole 32.

  Therefore, the space in which the parking pole 32 is installed can be reduced, and the left case 2 can be miniaturized accordingly.

  Further, according to the drive device 1 of the present embodiment, the bearing support 12 that rotatably supports the input shaft 14 via the bearing 13 is provided on the left vertical wall 5. In addition, a reinforcing rib 73 connected to the outer peripheral surface 12 a of the bearing support portion 12 is formed on the outer peripheral surface 5 a of the left vertical wall 5, and the outer peripheral surface 29 a of the lower recess 29 is interposed via the reinforcing rib 73. As a result, the bearing support 12 is connected to the outer peripheral surface 12 a.

  Thereby, the rigidity of the bearing support portion 12 can be increased by the reinforcing rib 73. Therefore, when the reaction force F1 (see FIG. 2) is applied from the input gear 15 via the input shaft 14 by the meshing between the input gear 15 and the counter gear 17 when the vehicle is traveling, the input support shaft 12 14 support rigidity can be made high.

  Further, the rigidity of the lower recess 29 can be increased by the reinforcing rib 73, and deformation and vibration of the lower recess 29 due to an external force can be suppressed. For this reason, the behavior of the manual plate 40 accommodated in the lower recess 29 can be stabilized.

  Further, since the reinforcing rib 73 extends along the circumferential direction of the bearing support portion 12, the rigidity of the input shaft 14 in the rotation direction can be increased, and the bearing rigidity of the bearing support portion 12 can be increased more effectively.

  Furthermore, since the rigidity of the lower concave portion 29 can be increased by the reinforcing rib 73 provided on the outer peripheral surface 5a of the left vertical wall 5, the bulging amount of the lower concave portion 29 with respect to the left vertical wall 5 can be set to the minimum bulging amount. It is possible to prevent the left case 2 from increasing in size.

  Further, according to the driving device 1 of the present embodiment, the mount member 75 for mounting the left case 2 to the vehicle body 76 is attached to the outer peripheral surface 5a of the left vertical wall 5 around the outer peripheral surface 12a of the bearing support portion 12. Boss portions 74A, 74B and 74C are provided.

  The upper recess 28 is provided on the upper side of a virtual plane L1 connecting the rotation center axis O1 of the input gear 15, the rotation center axis O2 of the counter gear 17 and the rotation center axis O3 of the final driven gear 22, 29 is provided on the lower side opposite to the upper concave portion 28 with respect to the virtual plane L1.

  Thereby, the upper recessed part 28 and the outer peripheral surface 12a of the bearing support part 12 are connected by the mount boss parts 74A, 74B, 74C, and the rigidity of the upper recessed part 28 can be increased.

  In addition, the second retainer 42 is connected to the left case 2 so as to straddle the lower recess 29, so that the bearing support 12 and the lower recess 29 can be reinforced. The rigidity of the side recess 29 can be increased.

  For this reason, the rigidity of the lower concave portion 29 and the upper concave portion 28 can be increased with respect to the reaction force F1 acting downward from the input shaft 14 and the reaction force F2 acting upward from the input shaft 14, and the parking rod 35 and the manual shaft 37 can be increased. And the behavior of the detent plate 38 can be stabilized.

  In addition, the space inside the upper recess 28 and the lower recess 29 can be minimized. As a result, the left case 2 can be more effectively downsized.

  Further, since the rigidity of the lower recess 29 can be increased by the second retainer 42, excessive formation of bosses or the like near the outer peripheral surface 29a of the lower recess 29 or the outer peripheral surface of the lower recess 29 can be realized. It is unnecessary to add. Therefore, the configuration of the left case 2 can be simplified accordingly.
