Description

The present invention relates to an operating lever device for an automatic transmission.

Conventionally, as an automatic transmission mounted on a vehicle, a stepped automatic transmission (AT: Automatic Transmission) and a continuously variable transmission (CVT) are widely known.

The automatic transmission has a shift range (shift range) including a P range, an R range, an N range, and a D range. A shift lever (select lever) is provided in the passenger compartment of the vehicle in order to switch between these shift ranges. In the range of motion of the shift lever, P position, R position, N position and D position are set as shift positions corresponding to the shift range.

The automatic transmission is provided with a control shaft. An outer lever is attached to one end of the control shaft. One end of the shift cable (control cable) is connected to the outer lever, and the other end of the shift cable is connected to the shift lever. The other end of the control shaft is connected to the spool of the manual valve. As a result, when the shift lever is operated, the operation is input to the outer lever via the shift cable, and the input causes the control shaft to rotate. Then, as the control shaft rotates, the spool of the manual valve moves, and the hydraulic pressure is output from the output port corresponding to the shift position, so that the P range, R range, N range, or D range can be selectively selected. It is composed.

Further, each of the shift lever and the control shaft is provided with a detent mechanism including a plate-shaped member having a wavy portion in which irregularities are alternately arranged and an elastic member elastically fitted in a concave portion of the wavy portion. The detent mechanism is provided not only for the purpose of giving a sense of moderation to the operation of the shift lever and the rotation of the control shaft, but also for the purpose of positioning the shift lever and the control lever when assembling the shift cable. For example, when assembling the shift cable, the shift position and the shift range can be matched by positioning the shift lever at the N position and positioning the control lever (outer lever) at the rotation position where the N range is formed. it can.

However, since each lever is positioned only by the load of the detent mechanism, the shift position and the shift range are likely to deviate when the cable is connected.

If the shift position and shift range deviate from each other, the display of the shift indicator provided on the meter panel may differ from the shift position, or the phase of the shift lever detent mechanism and the control shaft detent mechanism may deviate, resulting in impaired moderation. To do. If the position of each lever is fixed by using a jig pin or the like, it is possible to prevent the shift position and the shift range from shifting, but the man-hours and cost required for assembling the shift cable increase.

An object of the present invention is to provide an operating lever device for an automatic transmission capable of suppressing a shift between a shift position and a shift range while suppressing an increase in man-hours and costs required for assembling a cable.

In order to achieve the above object, the operation lever device of the automatic transmission according to the present invention has an operation lever rotatably provided with the lever shaft as a fulcrum, one end connected to the operation lever, and the other end of the automatic transmission. To push down the rod, which is attached to the tip of the operating lever and a rod having a grooved pin that is inserted into the operating lever and is movable in the insertion direction and extends in a direction intersecting the insertion direction. A knob having a knob button pressed against the lever and a gate plate having a gate window through which the grooved pin is inserted are included, and the grooved pin is moved to the upper end of the gate window with the rotation of the operating lever without pressing the knob button. A permissible groove and a recess that is recessed from the groove to the knob side and into which a grooved pin can be inserted are formed. With the knob not attached to the tip of the operating lever, the grooved pin is fitted in the recess and the knob is the operating lever. When attached to the tip, the rod is pushed down by the knob so that the grooved pin comes out of the recess into the groove.

According to this configuration, the gate window of the gate plate is formed with a groove portion that allows the grooved pin to move with the rotation of the operating lever without pressing the knob button, and a recess recessed from the groove portion toward the knob side. .. In the state before the knob is attached to the tip of the operating lever, the grooved pin is fitted in the recess. Therefore, the movement of the grooved pin is restricted, and the rotation of the operating lever is restricted accordingly. As a result, when the cable is connected to the operation lever, it is possible to prevent the operation lever from being displaced without using a jig pin or the like. Therefore, it is possible to suppress the deviation between the position of the operation lever (shift position) and the shift range of the automatic transmission while suppressing the increase in man-hours and cost required for assembling the cable.

Further, since the position of the gate plate is determined based on the recess, it is possible to suppress the variation in the relative position between the grooved pin and the gate window of the gate plate. As a result, the operation feeling of the operation lever can be improved.

According to the present invention, it is possible to suppress the deviation between the shift position and the shift range while suppressing the increase in man-hours and cost required for assembling the cable, and also suppress the variation in the relative position between the grooved pin and the gate window of the gate plate. It is possible to improve the operation feeling of the operation lever.

It is a right side view of the shift lever device which concerns on one Embodiment of this invention. It is a left side view of the shift lever device. It is the right side view of the shift lever device, and shows the state in which the shift knob is removed from the shaft of the shift lever.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

<Shift lever device>
FIG. 1 is a right side view of the shift lever device 1 according to the embodiment of the present invention. FIG. 2 is a left side view of the shift lever device 1.

The shift lever device 1 is mounted on a vehicle together with a stepped or continuously variable automatic transmission, and is provided, for example, on an instrument panel in the vehicle interior. The shift lever device 1 includes a cover 11, a shift lever 12, a base plate 13, and a gate plate 14.

The cover 11 has an arcuate plate shape having a width in the left-right direction of the vehicle, and is arranged so that its surface protrudes from the instrument panel toward the vehicle interior side. Although not shown, the cover 11 is formed with a shift groove extending in the front-rear direction of the vehicle penetrating in the vertical direction.

The shift lever 12 is provided so as to penetrate the shift groove of the cover 11 and straddle the inside and outside of the vehicle interior. The shift lever 12 has a double shaft structure, and includes an outer substantially cylindrical shaft 21 and a substantially cylindrical rod 22 inserted through the shaft 21.

The rod 22 is provided so as to be able to reciprocate in the axial direction of the shaft 21, and is urged to the upper side (shift knob 26 side) by the elastic force of the spring 23. A grooved pin 24 is integrally provided in the middle portion of the rod 22. The grooved pin 24 projects to the right from the rod 22 at a position below the cover 11, is inserted into the pin groove 25 formed in the shaft 21, and further extends to the right.

A shift knob 26 is attached to the upper end of the shaft 21. The upper end of the rod 22 protrudes from the shaft 21 and is inserted into the shift knob 26. A block 27 is attached to the upper end of the rod 22. The block 27 is formed with an inclined surface inclined downward to the right so as to be located on the right side toward the lower side.

A button arrangement port 28 is formed on the right side surface of the shift knob 26. The shift knob 26 is provided with a knob button 29 protruding to the right from the button arrangement port 28. The knob button 29 is urged to the right by the elastic force of a coil spring (not shown). When the knob button 29 is pushed into the shift knob 26 against this urging force, the inclined surface of the block 27 is pressed by the knob button 29, and the pressing force is converted into a downward force on the inclined surface to convert the rod 22 into a downward force. Moves down.

As shown in FIG. 2, the base plate 13 is arranged on the lower side (outside the vehicle interior) of the cover 11 on the left side of the shift lever 12, and extends in the front-rear direction and the up-down direction. A lever shaft 31 extending to the left side is integrally provided at the lower end of the shift lever 12. By rotatably inserting and holding the lever shaft 31 through the base plate 13, the shift lever 12 is swingably supported around the lever shaft 31 as a fulcrum. In the movable range of the shift lever 12, for example, the P (parking) position, the R (reverse) position, the N (neutral) position, the D (drive) position, the S (sports) position and the B (brake) position are on the front side in this order. They are arranged in a row on the rear side.

An arm 32 is provided at the right end of the lever shaft 31 so that it cannot rotate relative to each other. One end of the shift cable (control cable) 33 is connected to the tip of the arm 32, and the other end of the shift cable 33 is connected to the outer lever (not shown) of the automatic transmission.

As a result, when the shift lever 12 is operated, the operation is input to the outer lever via the shift cable 33, and the control shaft is rotated by the input. Then, as the control shaft rotates, the spool of the manual valve moves, and hydraulic pressure is output from the output port corresponding to the shift position of the shift lever 12, so that the automatic transmission has a P corresponding to the shift position. Range, R range, N range or D range are selectively configured.

Regardless of whether the shift lever 12 is in the D position, the S position, or the B position, the automatic transmission constitutes the D range. However, in the state where the shift lever 12 is located in the S position, the gear ratio is changed so that the engine speed is maintained higher than in the state where the shift lever 12 is located in the D position. As a result, the driver can enjoy sporty driving by arranging the shift lever 12 in the S position. Further, when the shift lever 12 is arranged in the S position, a strong engine brake can be obtained during deceleration. When the shift lever 12 is in the B position, the gear ratio is changed so that the engine speed is maintained higher than that in the S position, and a stronger engine brake can be obtained during deceleration.

The gate plate 14 is arranged on the lower side of the cover 11 on the right side of the shift lever 12 and extends in the front-rear direction and the up-down direction. A gate window 41 is formed in the gate plate 14 so as to penetrate in the left-right direction at a position facing the grooved pin 24 in the left-right direction. At the upper end of the gate window 41, a first groove 42, a second groove 43, and a third groove 44 that are recessed upward are formed. The first groove portion 42 is formed at the front end portion of the gate window 41 corresponding to the P position of the shift lever 12. The second groove portion 43 is formed on the rear side of the first groove portion 42 with a partition wall 45 interposed therebetween, corresponding to the R position of the shift lever 12. The third groove portion 44 is formed on the rear side of the second groove portion 43 corresponding to the N, D, and S positions of the shift lever 12. The second groove portion 43 is opened to the rear side and communicates with the third groove portion 44. The third groove portion 44 is formed deeper than the second groove portion 43, and a step is formed between the second groove portion 43 and the third groove portion 44.

A grooved pin 24 is inserted through the gate window 41. Since the rod 22 is urged upward by the elastic force of the spring 23, the grooved pin 24 is in contact with the upper end of the gate window 41 when the knob button 29 is not operated. As a result, when the shift lever 12 is located at the P position, the grooved pin 24 is fitted into the first groove portion 42 corresponding to the P position. Since the partition wall 45 is provided between the first groove portion 42 and the second groove portion 43, the shift lever 12 cannot be moved from the P position without operating the knob button 29. By pushing the knob button 29, the rod 22 is lowered so that the grooved pin 24 is separated from the first groove portion 42, and the shift lever 12 can be moved from the P position to the R position. Further, when returning the shift lever 12 from the R position to the P position, the operation of the knob button 29 is required. Since the second groove portion 43 is open to the third groove portion 44 side, the shift lever 12 can be moved from the R position to the N position without pressing the knob button 29. On the other hand, the step between the second groove portion 43 and the third groove portion 44 restricts the movement of the grooved pin 24 from the third groove portion 44 to the second groove portion 43 side, so that the shift lever 12 is moved from the N position to the R position. To move it, it is necessary to press the knob button 29. When the grooved pin 24 is fitted in the third groove 44 corresponding to the N, D, S positions, the shift lever 12 can be moved between the N, D, and S positions without pressing the knob button 29. .. When moving the shift lever 12 from the S position to the B position, it is necessary to press the knob button 29 in order to separate the grooved pin 24 from the third groove 44.

<Shift lock mechanism>
The shift lever device 1 is provided with a shift lock mechanism 51. The shift lock mechanism 51 includes a shift lock cam 52 and a solenoid 53.

The shift lock cam 52 is provided so as to be swingable between a regulated position and an allowable position with a shaft portion 54 extending in the left-right direction as a fulcrum. A plunger 55 of the solenoid 53 is connected to the end of the shift lock cam 52.

When the solenoid 53 is not energized, the plunger 55 advances from the main body of the solenoid 53, the shift lock cam 52 is located at the regulation position, and the regulation portion 56 provided so as to project upward from the shift lock cam 52 is gated. The first groove 42 of the window 41 is closed from below. Therefore, when the shift lever 12 is located in the P position and the grooved pin 24 is fitted in the first groove portion 42, the movement path of the grooved pin 24 is blocked, and even if the knob button 29 is pressed, the grooved pin 24 is the first. The shift lever 12 cannot be moved from the P position without detaching from the groove portion 42.

For example, when the brake pedal is stepped on while the vehicle ignition switch (start switch) is on, the solenoid 53 is energized, and when the plunger 55 is pulled toward the main body of the solenoid 53, the shift lock cam 52 is moved from the regulated position. Rotating to an allowable position, the regulating portion 56 opens the first groove portion 42. As a result, the shift lever 12 can be moved from the P position by pressing the knob button 29.

<Detent mechanism>
As shown in FIG. 2, the shift lever device 1 is provided with a detent mechanism 61. The detent mechanism 61 includes a detent plate 62 and a spring member 63.

The detent plate 62 is formed integrally with the arm 32, for example, and when the shift lever 12 is operated, the detent plate 62 rotates integrally with the lever shaft 31. The tip surface of the detent plate 62 is formed with irregularities corresponding to the P, R, N, D, S, and B positions of the shift lever 12.

The base end of the spring member 63 is fixed to the base plate 13, and the tip of the spring member 63 is elastically in contact with the tip surface of the detent plate 62. The position of the spring member 63 is adjusted based on the state in which the shift lever 12 is located at the N position.

As a result, an appropriate sense of moderation can be obtained when the shift lever 12 is located at each of the P, R, N, D, S, and B positions.

<N holding groove>
FIG. 3 is a right side view of the shift lever device 1 and shows a state in which the shift knob 26 is removed from the shaft 21 of the shift lever 12.

In the shift lever device 1, with the shift knob 26 removed from the shaft 21 of the shift lever 12, as shown in FIG. 3, the rod 22 is positioned relatively upward by the elastic force of the spring 23, and the shift knob 26 is moved. When attached to the shaft 21, the shift knob 26 presses the rod 22 downward so that the position of the rod 22 is slightly lowered, as shown in FIG.

The gate plate 14 is formed with a recess 71 that is recessed upward (on the shift knob 26 side) from a position corresponding to the N position of the second groove portion 43. The recess 71 is formed in a size into which the grooved pin 24 can be fitted.

Therefore, when the shift lever 12 is located in the N position and the shift knob 26 is removed from the shaft 21, the grooved pin 24 is fitted into the recess 71 as shown in FIG. Therefore, the shift lever 12 cannot be moved from the N position. As shown in FIG. 1, when the shift knob 26 is attached to the shaft 21 and the position of the rod 22 is lowered, the grooved pin 24 is separated from the recess 71 and can move in the second groove 43.

<Effect>
As described above, the gate window 41 of the gate plate 14 has a second groove portion 43 and a second groove portion 43 that allow the grooved pin 24 to move with the rotation of the shift lever 12 without pressing the knob button 29 of the shift knob 26. A recess 71 is formed on the shift knob 26 side. In the state before the shift knob 26 is attached to the tip of the shift lever 12, the grooved pin 24 is fitted in the recess 71. Therefore, the movement of the grooved pin 24 is restricted, and the movement of the shift lever 12 is restricted accordingly. As a result, when the shift cable 33 is connected to the shift lever 12 (arm 32), it is possible to prevent the shift lever 12 from being displaced without using a jig pin or the like. Therefore, it is possible to suppress the deviation of the position (shift position) of the shift lever 12 and the shift range of the automatic transmission while suppressing the increase in man-hours and cost required for assembling the shift cable 33.

Further, since the position of the gate plate 14 is determined based on the recess 71, it is possible to suppress the variation in the relative position between the grooved pin 24 and the gate window 41 of the gate plate 14. As a result, the operation feeling of the shift lever 12 can be improved.

Further, since the position of the spring member 63 of the detent mechanism 61 is adjusted based on the state where the shift lever 12 is located at the N position, the position of the shift lever 12 and the position of the grooved pin 24 with respect to the gate window 41 of the gate plate 14 And the position of the spring member 63 with respect to the detent plate 62 can be aligned. Therefore, a better operation feeling of the shift lever 12 can be obtained.

<Modification example>
Although one embodiment of the present invention has been described above, the present invention can also be implemented in other embodiments.

For example, in the above-described embodiment, the recess 71 is formed to be recessed upward from the position corresponding to the N position of the second groove 43, but the recess 71 is the position or S position corresponding to the D position of the second groove 43. It may be formed on the upper side of the position corresponding to.

In addition, various design changes can be made to the above-mentioned configuration within the scope of the matters described in the claims.
