Description

  The present invention relates to an operation device for a gear-meshing type transmission in which a gear position is switched by a select operation and a shift operation, and more specifically, a gear having reduced play between members to be operated and a simplified structure. The present invention relates to an operating device for a meshing transmission.

  As one type of transmission mounted on a vehicle, a plurality of transmission gear sets that rotate freely between two parallel rotating shafts are provided, and one transmission gear set is selectively meshed and coupled by a synchronization device to achieve a predetermined speed change. There is a meshing gear type transmission that realizes a gear ratio. This transmission employs a structure in which one synchronizer is provided for two shift speeds and is operated by a fork shaft, and in a configuration of five or more forward speeds, three or more sets of synchronizers and fork shafts are provided. A shift-and-select shaft is provided in the operating device to perform a selection operation for selecting the fork shaft and a shift operation for driving the selected fork shaft.

  As a more detailed structure, the shift and select shaft has an inner lever integrally. The inner lever engages with a shift head of one of the fork shafts as the shaft rotates, and performs a select operation, and shifts the fork shaft that has been selected as the shaft moves in the axial direction. The operation of the shift and select shaft is performed by transmitting the operation of the shift lever by the driver through an operation cable in the manual transmission, and by an actuator such as a motor in the automatic transmission. Furthermore, the operation device generally includes an interlock mechanism that restricts the shift operation of the fork shaft that has not been selected, and a detent mechanism that stabilizes the operation by reducing backlash at each part.

  An example of an operation device for this type of gear-meshing type transmission is disclosed in Patent Document 1. The manual transmission operating mechanism disclosed in Patent Document 1 includes a transmission case, a plurality of shift fork shafts, a shift select shaft, an inner lever, and an interlock member. The transmission case is provided with two guide portions to guide the interlock member in a posture orthogonal to the shift select shaft. As a result, the tilting in the axial direction can be prevented while allowing the interlock member to rotate.

  Furthermore, in the embodiment of Patent Document 1, a select operation input portion is formed on the interlock member, and the interlock member is rotated by an operation from an inner select lever (corresponding to the select member of the present invention). A mode in which the lever also rotates is described. In this aspect, the select operation force is input to the inner select lever from the shift lever or actuator serving as the operation source, and is transmitted to the inner lever via the interlock member. Similar transmission paths for the select operation force are disclosed in Patent Documents 2 and 3.

  Further, in order to reduce the play when the inner lever operates, it has been common to provide a detent mechanism between the shift and select shaft and the case.

  By the way, in Patent Documents 1 to 3, the select operation force is transmitted from the inner select lever to the inner lever via the interlock member. For this reason, play occurs between the inner select lever and the interlock member and between the interlock member and the inner lever, that is, at two places. In addition, the detent mechanism provided on the shift and select shaft can reduce the backlash of the integrally formed inner lever, but it is structurally difficult to reduce the backlash of the separate inner select lever and interlock member. It has become. Therefore, in the manual transmission, the operation play of the shift lever is increased and the operation feeling is lowered, and in the automatic transmission, the operation play of the actuator is increased and the smoothness of the operation is impaired. Further, there is a concern that the operational reliability of the speed change operation is lowered due to the large structural play, and it is important in terms of performance to reduce the play.

  Moreover, the guide part of the interlock member disclosed by patent document 1 uses the structure which forms a concave part in the inner surface of a transmission case, and pinches | interposes an interlock member, The structure is large and complicated.

And an interlock member that regulates the operation of the gear meshing transmission, wherein the select member abuts against the shift-and-select shaft or the inner lever and is pushed directly.

  Furthermore, the inner lever extends in a radial direction different from the engagement head, and an engagement head that extends in a radial direction of the shift-and-select shaft and engages any one of the shift heads. The select member has a shaft portion that is rotatably supported, and a select drive portion that protrudes radially from the shaft portion and engages with the select follower portion of the inner lever. When the operating force is applied and the shaft portion rotates, it is preferable that the select driving portion abuts on the select follower portion and directly pushes.

  Furthermore, it is preferable to further include a detent mechanism that is provided on the shaft portion of the select member and restricts the rotation of the shaft portion when the operating force is not applied.

  Further, the interlock member has a groove portion carved in a direction orthogonal to the axial direction of the shift and select shaft, and the select member has the shaft portion arranged in parallel to the shift and select shaft. An interlock axial direction restricting portion that is immovable in the axial direction and protrudes in the radial direction from the shaft portion and engages with the groove portion of the interlock member may be provided.

  Furthermore, it is preferable that the select drive unit also serves as the interlock axial direction regulating unit.

  The select member and the shift member may be operated from a shift lever operated by an operator via an operation cable.

  The select member and the shift member may be operated by an actuator.

  In the operation device of the gear meshing transmission according to the present invention, the select member abuts on the shift and select shaft or the inner lever and pushes directly, and does not pass through the interlock member as in the prior art. Therefore, in the present invention, the occurrence position of the play that has been two places is one place in the present invention, the play can be reduced as compared with the conventional case, and the operation reliability is improved.

  Further, in the aspect in which the inner lever has the select driven portion and the select member has the select drive portion, the occurrence of the play that has conventionally been two places is one place between the select drive portion and the select follower portion in the present invention. Therefore, the backlash can be reduced more than before, and the operation reliability is improved.

  In an aspect in which the shaft portion of the select member is further provided with a detent mechanism, unnecessary swinging of the select member is suppressed by the detent mechanism. Therefore, the play in the shift lever or actuator on the upstream side of the select member and the play on the inner lever on the downstream side are further reduced, and the operation reliability is improved overall.

  Further, in the aspect in which the interlock member has the groove portion and the select member has the interlock axial direction restricting portion, the select member restricts the interlock member in the axial direction. Therefore, the structure can be simplified as compared with the conventional structure in which the interlock member is restricted by the concave portion on the inner surface of the transmission case.

  Furthermore, in the aspect in which the select drive unit also serves as the interlock axial direction restricting unit, the number of components of the operating device can be reduced as compared with the prior art, and the structure can be further simplified.

  Further, in the aspect in which the select member and the shift member are operated from the shift lever, the operation feeling of the shift lever in the manual transmission can be improved and the operation reliability can be improved.

  Further, in the aspect in which the select member and the shift member are operated by the actuator, the operation smoothness of the actuator in the automatic transmission can be improved and the operation reliability can be improved.

Further, the inner lever 6 has a select follower 62 that extends in a radial direction different from that of the engagement head 61, in the present embodiment, upward in the radial direction opposite to the engagement head 61. The select driven portion 62 has a pair of protrusions 65 and 66 extending in parallel upward in FIG. 1 and a driven recess 67 opening upward in a space formed therebetween.

  The outer select lever 3 is a member that rotates the shift and select shaft 2 around the axis AX1. The outer select lever 3 includes a shaft portion 31, a lever portion 32, and a select driving portion 35 that are integrated. As shown in FIG. 3, the shaft portion 31 is disposed in the horizontal direction so that its axis AX2 is parallel to the shift and select shaft 2, and is rotatably supported by the case 91 via the bearing member 93. ing. In addition, a flange portion 34 that protrudes radially outward is provided in the middle of the shaft portion 31, and the flange portion 34 is in sliding contact with the case 91 to restrict movement of the shaft portion 31 in the axis AX2 direction.

  A lever portion 32 extends in the radial direction from one end of the shaft portion 31 (the left front end in FIG. 1), and a select operation cable mounting pin 33 is erected near the tip of the lever portion 32. The mounting pin 33 is connected to a shift lever (not shown) operated by a driver with a select operation cable (not shown).

The detent member 81 is integrally extended upward from the cylindrical portion 36, and a detent groove portion 82 that is parallel to the direction of the axis AX1 is formed at the center of the upper surface thereof. Detent hill portions 83 and 84 that swell upward are formed on both sides of the detent groove 82, and detent end portions 85 and 86 that are lowered downward are formed outside the detent hill portions 83 and 84.

  The detent ball 88 rolls on the detent hill portions 83 and 84 on the upper surface of the detent member 81 and enters the detent groove portion 82 or one of the detent end portions 85. As shown in FIG. 3, the detent spring 89 is accommodated in a hole 94 formed in the case 91, one end is fixed to the case 91 side, and the detent ball 88 is pressed against the detent member 81 at the other end. It is arranged like this. The detent ball 88 is held by a member not shown in the drawing, and operates stably without dropping.

  When the shaft portion 31 of the outer select lever 3 is rotated, an operating force is required to take out the detent ball 88 from the detent groove portion 82 or the detent end portion 85. Further, after the turning operation, the detent ball 88 settles on the detent groove portion 82 or one of the detent end portions 85. Each of the detent groove portion 82 and both detent end portions 85 and 86 corresponds to a state in which one of the triaxial fork shafts 5 is selected. Due to the action of the detent mechanism 8, the outer select lever 3 is hardly rattled.

  The outer shift lever 4 is a member that moves the shift and select shaft 2 in the direction of the axis AX1. As shown in FIG. 1, the outer shift lever 4 includes a shaft portion 41, a lever portion 42, and a shift drive arm portion 45 that are integrated. The shaft portion 41 is arranged in the vertical direction so that its axis AX3 is perpendicular to the shift-and-select shaft 2, and is supported so as to be rotatable about the axis AX3 and not movable in the direction of the axis AX3. A lever portion 42 extends in the radial direction from the upper end of the shaft portion 41, and a shift operation cable mounting pin 43 is erected near the tip of the lever portion 42. The mounting pin 43 is connected to a shift lever (not shown) operated by a driver with a shift operation cable (not shown).

  The interlock member 7 is a member that restricts movement by engaging with the shift head 51 of the remaining fork shaft 5 that the inner lever 6 has not selected. As shown in FIGS. 1 and 2, the interlock member 7 includes an upper surface portion 71 disposed on the upper side of the inner lever 6 and both side surface portions 72 and 73 disposed on the outer side of the side surface of the inner lever 6. The lock heads 74 and 75 provided at the lower ends of the side surfaces 72 and 73 are integrally formed. As shown in FIG. 4, the length D <b> 7 in the direction of the axis AX <b> 1 of the upper surface portion 71 and the side surface portions 72 and 73 is set to be approximately the same as the thickness D <b> 6 of the inner lever 6.

  As shown in FIG. 2, the distance between the two side portions 72 and 73 is narrowed downward so as to approach the engagement head 61 of the inner lever 6. And the lock heads 74 and 75 are provided toward the downward direction from the lower end of each side part 72 and 73. As shown in FIG. The two lock heads 74 and 75 are arranged so as to sandwich the engagement head 61 of the inner lever 6. Further, the arrangement pitch of the two lock heads 74 and 75 and the engagement head 61 coincides with the arrangement pitch of the shift head 51 of the triaxial fork shaft 5.

  Further, as shown in FIGS. 1 and 4, the upper surface 71 of the interlock member 7 is provided with a groove 77 in a direction orthogonal to the direction of the axis AX1. The drive lever 37 of the outer select lever 3 is fitted into the driven recess 67 of the engagement head 61 of the inner lever 6 through the groove 77. At this time, the movement of the groove 77 in the direction of the axis AX1 is restricted by the drive lever 37. That is, the drive lever 37 of the outer select lever 3 also serves as the interlock axial direction restricting portion of the present invention.

  With the configuration described above, the inner lever 6 is housed inside the interlock member 7, and the interlock member 7 also rotates as the inner lever 6 rotates. Further, the lock heads 74 and 75 of the interlock member 7 are engaged with the engagement recess 57 of the shift head 51 where the engagement head 61 of the inner lever 6 is not engaged. Even when the inner lever 6 moves in the direction of the axis AX1, the interlock member 7 does not move and performs a locking function.

  Next, the operation of the operation device 1 of the gear meshing transmission according to the embodiment configured as described above will be described. When the driver selects the shift lever, the operating force is transmitted by the select operation cable, and the lever portion 32 of the outer select lever 3 swings. For example, when the lever portion 32 swings clockwise as indicated by an arrow R1 in FIG. 1, the entire shaft portion 31 swings clockwise as indicated by an arrow R5 in FIG. As a result, the drive lever 37 (select drive unit 35) of the outer select lever 3 abuts on the driven recess 67 (select driven unit 62) of the inner lever 6 and is pushed directly, and the driven recess 67 is shown in FIG. Swings in the direction.

  By this operation, the inner lever 6 and the shift and select shaft 2 are rotated counterclockwise as indicated by the arrow R6, and the interlock member 7 is also swung counterclockwise. The engagement head 61 of the inner lever 6 is engaged with the shift head 51 of any of the fork shafts 5, and the lock head 74 of the interlock member 7 is connected to the shift head 51 of another adjacent fork shaft 5. 75 is engaged. This completes the select operation.

  Next, when the driver shifts the shift lever, the operating force is transmitted by the shift operation cable, and the lever portion 42 of the outer shift lever 4 swings. For example, when the lever portion 42 swings clockwise as indicated by an arrow R3 in FIG. 1, the tip 46 of the lever portion 42 axially moves the shift-and-select shaft 2 as shown by an arrow R7 in FIG. Move to the left front). As a result, as shown by an arrow R7 in FIG. 3, the shift and select shaft 2 moves in the axial direction, and the inner lever 6 also moves in the axial direction (left direction in the figure), as shown by the arrow R8. The selected fork shaft 5 is moved in the left direction (axial direction) in the figure. At this time, the interlock member 7 is restricted by the drive lever 37 of the outer select lever 3 and does not move. This completes the shift operation.

  In addition, when the operation directions of the outer select lever 3 and the outer shift lever 4 are opposite directions, the rotation direction and the axial direction of the shift and select shaft 2 change. At this time, since the operation of the controller device 1 is similar, description thereof is omitted.

  Next, the effect of the operation device 1 of the gear meshing transmission according to the embodiment will be described in comparison with the conventional configuration. FIG. 5 is a perspective view for explaining an operation device 10 of a gear meshing transmission having a conventional configuration. In the operation device 10 having a conventional configuration, an inner lever 106 is integrally provided on the shift and select shaft 102, and an interlock member 107 is disposed outside the inner lever 106. A rectangular hole-shaped select operation input portion 111 is formed on the interlock member 107, and the drive lever 112 of the outer select lever 103 is fitted therein.

  Therefore, when the outer select lever 103 is operated by an operation from the shift lever, the interlock member 107 is first rotated, and the inner lever 106 is also rotated at the same time. That is, in the conventional configuration, the select operation force is transmitted from the outer select lever 103 to the inner lever 106 via the interlock member 107, and play occurs at two locations.

  The detent mechanism 108 includes a detent member 113 provided on the shift and select shaft 102. The detent mechanism 108 is effective in reducing the play of the shift and select shaft 102 and the inner lever 106 integrally formed therewith, and it is difficult to reduce the play of the outer select lever 103 as a separate body. Therefore, the operation play of the shift lever is increased and the operation feeling of the driver is lowered.

  On the other hand, in the operation device 1 of the gear meshing transmission according to the embodiment, the outer select lever 3 abuts on the inner lever 6 and directly pushes, so that the play is generated at the drive lever 37 and the driven recess 67. It is one place between. Furthermore, since the detent mechanism 8 suppresses unnecessary swinging of the outer select lever 3, the play of the upstream shift lever and the downstream inner lever 6 is reduced. Therefore, the play in the operating device 1 can be reduced as compared with the prior art, the operation feeling of the shift lever in the manual transmission can be improved, and the operation reliability can be improved.

  Moreover, since the interlock member 7 has the groove part 77 and the drive lever 37 of the outer select lever 3 also serves as the interlock axial direction restricting part, the number of components of the operating device 1 can be reduced as compared with the prior art. The structure around can be greatly simplified.

  Note that the present invention is not limited to a manual transmission, and can also be implemented by an automatic transmission operated by an actuator. For example, if the present invention is implemented with an automatic transmission having a motor and a speed reduction mechanism instead of the outer select lever 3 and the outer shift lever 4, the play of the motor output shaft is reduced and the motor rotates smoothly. Can be improved. Various other modifications and applications of the present invention are possible.
