  As shown in FIG. 3, the GSU 1 includes a housing 4 in which a shaft 4 is supported so as to be rotatable and axially movable. The tip 4A of the shaft 4 is inserted into the transmission 21 and engaged with a striker (not shown) provided in the transmission 21 or a shaft member 22 to which the striker is connected. . Then, by moving the shaft 4 in the axial direction, the striker is moved in that direction to perform the selection operation of the transmission 21, and by rotating the shaft 4, the striker is rotated to perform the shift operation of the transmission 21. It is like that. The structure for engaging the tip portion 4A of the shaft 4 with the striker or the shaft member 22 is not particularly limited, and the locking groove 5 is provided in the example of FIG.

  Further, shaft holding holes 8a and 8b are formed in the housing 2, and the shaft 4 is held in the holding holes 8a and 8b so that the shaft 2 can move in the axial direction and rotate around the axis. It has become. A space 12 surrounding the shaft 4 is formed between the shaft holding holes 8 a and 8 b provided in the housing 2. An axial spline groove 4b (see FIG. 1B) and an engagement groove 4c are formed on the outer peripheral surface of the portion located in the space 12 of the shaft 4.

And is in a state of being freely rotatable and axially movable.

As shown in FIGS. 1 and 2, a selection motor 16 is attached to the housing 2, and a worm gear 18 is used as a first output rod connected to the selection motor 16. The worm gear 18 is disposed at a height different from that of the shaft 4 in a direction orthogonal to the axial direction of the shaft 4, and both end portions thereof are worm gear holding holes (not shown) provided in the housing 2. It is rotatably held by bearings 71 and 72 arranged in both end portions.

Are supported rotatably by bearings 73 and 74 disposed in both end portions.
In this embodiment, electric motors are used as the selection drive means and the shift drive means, respectively, but the present invention is not limited to this, and other drive means may be employed.

  Thus, the worm gear 18 as the output rod of the selection motor 16 and the ball screw 52 as the output rod of the shift motor 46 are arranged in a direction orthogonal to the shaft 4, respectively. The axial width is small. In the example of the GSU 1 of the present embodiment, since the shift motor 46 and the select motor 16 are arranged on both sides with the shaft 4 interposed therebetween, each member for shift operation and each member for select operation The degree of freedom of arrangement is increased. As a result, it is not necessary to increase the axial width of the shaft 4 of the GSU1, and the GSU1 is downsized. Therefore, as shown in FIG. 3, the protrusion width H from the attachment surface 21 </ b> A of the transmission 21 can be reduced in a state where the transmission 21 is attached to the transmission 21, and the mountability to the vehicle can be improved.

2. Next, the configuration of the GSU select operation transmission mechanism 10 will be described.
FIG. 4 is a perspective view showing the configuration of the select operation transmission mechanism 10 for transmitting the driving force of the select motor 16 as the select drive means to the shaft 4, and FIG. 5 is the select operation transmission mechanism 10 of FIG. 4. The top view which looked at from the upper side is shown. As shown in these drawings, a selection motor 16 is attached with a height different from that of the shaft 4 in a direction orthogonal to the shaft 4 held in a housing (not shown). A worm gear 18 as a first output rod is connected to a motor shaft (not shown) of the selection motor 16 via a rotation transmission member 82. A lever worm 90 as a part of the select operation transmission mechanism 10 is interposed between the worm gear 18 and the shaft 4. The lever worm 90 has a worm portion 91 as a rod engaging portion engaged with the worm gear 18 and a transmission lever portion 92 as a shaft engaging portion engaged with the shaft 4. The transmission lever portion 92 is integrated via a connecting portion 93 and extends with a phase shift of about 90 degrees around the connecting portion 93 serving as a rotation axis (see FIG. 4). The connecting portion 93 has projecting portions 93a and 93b at both ends in the rotation axis direction. The lower projecting portion 93b is held in a lever worm holding hole (not shown) provided in the housing 2, and the upper projecting portion 93 The portion 93a is held in a hole of a plug (indicated by 13 in FIG. 1) attached to the housing and is in a rotatable state.

The worm portion 91 of the lever worm 90 constitutes a worm mechanism together with the worm gear 18. The worm portion 91 rotates in the axial direction of the worm gear 18 in accordance with the rotation of the worm gear 18 driven by the selection motor 16. 90 itself also rotates. Further, the transmission lever portion 92 of the lever worm 90 is engaged with an engagement groove 4 c provided in the shaft 4, and the axial direction of the shaft 4 is accompanied by the rotation of the lever worm 90 driven by the above-described selection motor 16. The shaft 4 is moved in the axial direction. This transmission lever part 92 can adjust the transmission force at the time of transmitting the driving force of a motor to a shaft by changing length.
Therefore, when the selection motor 16 is driven, the worm gear 18 rotates via a motor shaft (not shown), and the worm portion 91 rotates in the axial direction of the worm gear 18. When the worm part 91 rotates, the transmission lever part 92 rotates in the axial direction of the shaft 4. Thereby, the selection operation of the transmission is performed.

  A rotation angle detection type select sensor 40 for detecting the select position of the shaft 4 is provided on the side surface side (lower side in FIG. 1) of the lever worm 90 of the housing. In the select sensor 40, a U-shaped groove (not shown) is formed at the tip of the detection lever 42, and an engagement pin (see FIG. 5) fixed to a sensor protrusion 94 protruding from a connecting portion 93 of the lever worm 90. 2). The select position of the shaft 4 is detected by detecting the swing position of the lever worm 90 by the select sensor 40. That is, when the shaft 4 moves in the axial direction by driving the selection motor 16, the lever worm 90 is also rotated by a predetermined amount. Therefore, by detecting the rotational movement amount of the lever worm 90, the axial direction of the shaft 4 is detected. The amount of movement to can be detected.

As described above, since the sensor protrusion 94 is provided on the lever worm 90 for transmitting the driving force of the selection motor 16 to the shaft 4 and is connected to the selection sensor 40, the degree of freedom of the sensor configuration and the arrangement position is increased. Is increased. Therefore, the select sensor 40 can be easily configured so as not to increase the size of the GSU as a whole.
Further, by arranging the select sensor 40 in this way, the select sensor 40 does not protrude from the surface opposite to the GSU transmission mounting surface, or the protrusion width is reduced even if it protrudes. Therefore, the axial width of the GSU shaft 4 can be reduced.

3. Next, the configuration of the shift operation transmission mechanism 11 of the GSU 1 will be described.
FIG. 6 is a perspective view showing a configuration of the shift operation transmission mechanism 11 for transmitting the driving force of the shift motor 46 to the shaft 4. 7A and 7B respectively show a side view of the shift operation transmission mechanism 11 of FIG. 6 viewed from the axial direction of the shaft 4 and a side view of the ball screw 52 viewed from the axial direction. . As shown in these drawings, a shift motor 46 is attached in a direction orthogonal to the shaft 4 held in a housing (not shown) so as to have a height different from that of the shaft 4. A ball screw 52 as a second output rod is connected to a motor shaft (not shown) of the shift motor 46 via a rotation transmission member 50, and a ball nut 54 is screwed to the ball screw 52. Has been. A lever sleeve 55 as a part of the shift operation transmission mechanism 11 is interposed between the shaft 4 and the ball screw 52. The lever sleeve 55 includes a sleeve portion 57 that engages with the shaft 4 and a transmission lever portion 56 that engages with a ball nut 54 that is screwed into the ball screw 52. The shaft 4 is splined to the spline groove 4b provided on the outer periphery of the shaft 4 in the sleeve portion 57 in which the spline groove 57a (see FIG. 7A) is formed on the inner peripheral surface. On the other hand, with respect to the ball nut 54, the distal end (lower end) side of the transmission lever portion 56 is engaged with a pair of engagement pins 54 a provided on both sides of the ball nut 54.

In this shift operation transmission mechanism 11, when the shift motor 46 is driven, the ball screw 52 rotates via a motor shaft (not shown), and the ball nut 54 moves in the axial direction on the ball screw 52, Accordingly, the transmission lever portion 56 rotates. When the transmission lever portion 56 rotates, the shaft 4 splined to the sleeve portion rotates. Thereby, the shift operation of the transmission is performed.
In addition, since the shift operation transmission mechanism 11 employs the lever sleeve 55 and engages the engaging portion with the shaft 4 by spline coupling, the operability of the axial movement of the shaft 4 by the above-described select operation. Can be secured.

A rotation angle detection type shift sensor 58 that detects the shift position of the shaft 4 is provided on the side surface side (upper side in FIG. 1) of the sleeve portion 57 of the housing. This shift sensor 58 has a U-shaped groove 60a formed at the tip of the detection lever 60, and projects from the lever sleeve 55 to the opposite side to the projecting direction of the transmission lever portion 56, like the select sensor described above. The engaging pin 62 is fixed to the protrusion 61. The shift position of the shaft 4 is detected by detecting the swing position of the sleeve portion 57 connected to the shaft 4 by the shift sensor 58.
By arranging the shift sensor 58 in this way, the shift sensor 58 does not protrude from the surface opposite to the GSU transmission mounting surface, or even if it protrudes, the protruding width can be reduced. For this reason, the axial width of the shaft 4 of the GSU can be reduced.

4). Operation Next, the operation of the GSU 1 of the present embodiment described so far will be described.
First, when a motor shaft (not shown) is rotated by driving the selection motor 16, the worm gear 18 connected to the motor shaft via the rotation transmission member 82 is rotated at a position held by the bearings 71 and 72. To do. When the worm gear 18 rotates, the worm portion 91 of the lever worm 90 that meshes with the gear portion of the worm gear 18 rotates in the axial direction of the worm gear 18. As the worm portion 91 rotates, the lever worm 90 rotates about the connecting portion 93 as a rotation axis, so that the transmission lever portion 92 of the lever worm 90 engaged with the engagement groove 4 c of the shaft 4 moves to the shaft 4. By moving in the axial direction, the lever worm 90 moves in the axial direction, and a select operation is performed.

  Thus, when the shaft 4 moves in the axial direction as the lever worm 90 rotates, the sensor protrusion 94 formed on the lever worm 90 rotates. A select sensor 40 is provided on a side surface of the housing 2 on the lever worm 90 side, and an engagement pin 44 fixed to the sensor projection 94 is connected to a detection lever 42 of the select sensor 40, so that the shaft 4 extends in the axial direction. The movement position, that is, the selection position of the transmission 21 is detected by the selection sensor 40 through the rotational movement of the sensor projection 94.

  Next, the shift motor 46 is driven to rotate the motor shaft, and the ball screw 52 is rotated via the rotation transmission member 50. By the rotation of the ball screw 52, the ball nut 54 moves in the axial direction of the ball screw 52, and the transmission lever portion 56 of the lever sleeve 55 engaged with the engagement pin 54a of the ball nut 54 rotates to move the sleeve portion 57. Rotate. Then, the shift operation of the transmission 21 is performed by rotating the shaft 4 splined to the sleeve portion 57.

  Thus, when the shaft 4 moves in the axial direction as the lever sleeve 55 rotates, the sensor protrusion 61 formed on the lever sleeve 55 rotates. A shift sensor 58 is provided on a side surface of the housing 2 on the sleeve portion 57 side, and an engagement pin 62 fixed to the sensor protrusion 61 is connected to a detection lever 60 of the shift sensor 58 so that the shaft 4 rotates in the rotational direction. The movement position, that is, the shift position of the transmission 21 is detected by the shift sensor 58 through the rotational movement of the sensor protrusion 61.

5. The configuration of the transmission operating device according to the present invention is not limited to the configuration described so far, and various modifications can be made.
For example, the select operation transmission mechanism for transmitting the drive force of the select drive means to the shaft is not limited to the configuration employing the worm mechanism as described above, and as shown in FIG. 8, the ball screw 111 and the ball nut The select operation transmission mechanism 110 having a configuration including 112 may be used.

  In the select operation transmission mechanism 110, a ball screw 111 is connected to a motor shaft (not shown) of a selection motor 116 via a rotation transmission member 182, and a ball nut 112 is screwed to the ball screw 111. A transmission member 190 having a first transmission lever portion 191 and a second transmission lever portion 192 is interposed between the ball screw 111 and the shaft 104, and the distal end side of the first transmission lever portion 191 is a ball nut 112. Are engaged with a pair of engagement pins 112 a provided on both sides thereof, and the distal end side of the second transmission lever portion 192 is engaged with an engagement groove 104 c provided on the shaft 104. In the select operation transmission mechanism 110, when the selection motor 116 is driven, the ball screw 111 rotates via the motor shaft and the rotation transmission member 182, and the ball nut 112 moves in the axial direction on the ball screw 111. In response to this, the first transmission lever portion 191 rotates. When the first transmission lever portion 191 rotates, the transmission member 190 itself rotates and the second transmission lever portion 192 engaged with the engagement groove 104c of the shaft 104 rotates in the axial direction of the shaft 104. The shaft 104 moves in the axial direction. Thereby, the selection operation of the transmission is performed.

  However, for the select operation, a selection operation of a plurality of shafts provided in the transmission is performed, and a high output is often not required. Therefore, from the viewpoint of suppressing an increase in production cost, as described above. It is a more preferable aspect to use a lever worm that employs a worm mechanism.

  On the other hand, the shift operation transmission mechanism can also be configured using the worm mechanism as described in the above select operation transmission mechanism, but the shift operation is fixed to the shaft of the transmission selected by the select operation. The shift fork is moved so that the gears mesh with each other. A strong force is required, and it is desirable to shorten the shift completion time as much as possible. Therefore, since the transmission operating device is required to have a high output and excellent responsiveness, it is preferable to use a configuration using the ball screw as described above.

Various changes can be made to the arrangement of the select sensor and the shift sensor.
For example, for the select sensor, as shown in FIG. 9, the lever worm 195 is not provided with a sensor protrusion, and the shaft sensor 140 is engaged so as to be coaxial with the rotation axis of the connecting portion 193 of the lever worm 195. Can be configured. By arranging in this way, it is possible to arrange the shaft 104 so as not to hinder the operation of the shaft 104 and to increase the axial width of the shaft 104.
However, in this case, when the GSU is mounted in the lateral direction of the transmission, the connector part 141 of the shaft sensor 140 faces upward, and water and dust are likely to be collected, and water may be sucked into the terminal side. . Therefore, in any case of using any of the sensors, it is preferable that the connector portion does not face upward in consideration of the state of attachment to the transmission.

On the other hand, with respect to the shift sensor, as shown in FIG. 10, the lever sleeve 155 is not provided with a sensor protrusion, and the engaging pin 162 is fixed at an intermediate position between the transmission lever portion 156 and the sleeve portion 157. A U-shaped groove 160a formed at the tip of the detection lever 160 of the sensor 158 can be engaged. Even with this arrangement, the arrangement of the shaft 104 can be prevented from being hindered.
However, in this case, since the position where the shift sensor 158 is disposed is located on the opposite side of the mounting surface to the transmission, the axial width of the shaft 104 of the GSU may be increased. Therefore, as shown in FIG. 6, it is preferable to configure the shift sensor using the sensor protrusion 61 that protrudes from the sleeve portion 57 of the lever sleeve 55.

  Further, the present invention does not necessarily require that the shift driving means and the select driving means are arranged on both sides of the shaft, and the positions of the two motors overlap when viewed from the axial direction of the shaft. There is no particular limitation as long as there is no positional relationship. However, as shown in FIG. 2, the two motors are separated by arranging them on both sides around the shaft, and the degree of freedom of arrangement of each member for shift operation and each member for select operation can be further increased. .
