Abstract

PURPOSE:To enable to shift the gear position to a reverse drive position with no need of any special operation and to prevent unintentional shifting of gears from a forward drive position to the reverse drive position at the same select position, by employing such an arrangement that movement of dogs is prevented through lapping of the dogs when the gear position is shifted directly from a forward drive position to a reverse drive position. CONSTITUTION:When gears are shifted to the fifth-speed forward drive position, forward movement of a dog 13 is prevented by a pin 17, so that the dog 13 comes out of engagement with a dog 12 and returns to its normal position through reverse turning. Therefore, the dogs are held in place in the manner that their tooth tips are opposed to each other. If the gears are shifted directly to a reverse drive position without changing a select position, reverse movement of the dog 13 is prevented by a stopper hole 15 and the pin 17. However, when the gears are shifted in the normal manner by cancelling the fifth-speed forward drive position, the top 1a of a shift lever is disengaged from a retainer groove 8 and a yoke 9 is returned to its normal position by the force of a spring 10. Then, the dog 13 is moved forward and comes into engagement with the dog 12 by a spring 18 and the gears restore the original position.

In an automobile's manual transmission, each gear shift stage is selected by a select operation and a shift operation of a shift lever. For example, in a transmission with 5 forward speeds and 5 reverse speeds, the shift pattern of the shift lever is generally set to a double H type, with 1 and 2
speed, 3rd and 4th gears in the center, 5th gear on the right edge, R (reverse)
After combining the speeds and selectively operating the shift lever left and right, the desired speed stage is selected by shifting forward and backward.

With such a shift pattern, when downshifting from fifth speed to another forward speed while driving, it is likely that the vehicle will erroneously shift to reverse speed at the same select position. Since the transmission gear is rotating at high speed, a complete shift to reverse gear does not occur, but
The gears make unpleasant noises and can sometimes damage the gears. To prevent this, some models require a separate operation, such as pushing down the shift lever or operating an attached button or lever, to shift to reverse speed.

The illustrated transmission has five forward speeds and one reverse speed. The shift hawks 5, 5 that select the meshing of the gears of the transmission gear mechanism are the three shift shafts 2,
3 and 4, respectively. The shift shaft 2 moves forward from an intermediate position (neutral position) to shift the gear engagement to the first gear, and moves backward to shift the gear engagement to the second gear.
The shift shaft 3 moves forward to third speed, moves backward to fourth speed, and the shift shaft 4 moves forward to fifth speed, and moves backward to gear engagement of reverse speed. Shifting of these shift shafts 2, 3, and 4 is performed by a shift lever 1. As shown in the shift pattern shown in Fig. 3, by selecting the left and right sides of the shift lever 1, the tip 1a of the lever is placed in one of the locking grooves 6, 7, and 8 provided in the shift shafts 2, 3, and 4. By selectively engaging and shifting the shift lever 1 back and forth at that position, the engaged shift shafts 2, 3, and 4 move forward or backward, and the speed stage is selected as described above.

Next, a yoke 9 is integrally supported in the axial direction and pivotally supported in the circumferential direction on the forward-reverse shift shaft 4 that combines fifth speed and reverse speed. A locking groove 8 is provided on the side surface of the yoke 9 facing the shift lever tip 1a, and a dog 12 is formed on the end surface of the boss. The spring 10 and the stopper 11 always hold the shift lever at a constant circumferential position (original position) inclined toward the tip 1a of the shift lever. When the shift lever 1 is selected, the lever tip 1a engages with this locking groove 8. At this time, the yoke 9 is pushed by the lever tip 1a and is set to swing at an angle of θ against the spring 10. has been done.

In addition, on the shift shaft 4, there is the above-mentioned dog 1.
A regulation dog 13 that engages with the shaft 2 is rotatably and axially slidably supported. This regulation dog 13 is
The movable range in the axial and circumferential directions is regulated by a stopper hole 15 drilled in the boss 14 and a pin 17 protruding from the transmission case 16, and at the same time, the movable range in the circumferential and axial directions is always controlled by the spring 18. It is spring-biased and held in its home position (return position). The posture of the regulation dog 13 in this fixed position is
The yoke 9 is set to snugly mesh with the dog 12 when normally held in a fixed position. That is, when the shift lever 1 is not selecting the shift shaft 4, the dog 12 and the restriction dog 13 are always engaged. The movable range of the regulating dog 13 by the stopper hole 15 and the stopper pin 17 is that it can rotate in the circumferential direction by an angle θ in the same direction as the yoke 9 swings, and in the axial direction with respect to the fixed position. teeth,
The shift shaft 4 is set so that it can be displaced rearward by the stroke required for shifting, but cannot be displaced forward to shift to forward speed.

When the shift shaft 4 of the fifth speed and reverse (R) speed is selected by the select operation of the shift lever 1, the lever tip 1a engages with the locking groove 8 and moves the yoke 9 from a fixed position (original position) with a spring. It is swung at an angle of θ against a spring force of 10. As a result of this swinging, the regulating dog 13 meshing with the dog 12 is also simultaneously swinging against the spring force of the spring 18 (FIG. 4). By shifting the shift lever 1 in this swing position, the shift shaft 4 is moved forward or backward together with the yoke 9,
5th speed or reverse speed can be selected, but at this time dog 12 and regulation dog 13
works as follows.

First, when shifting to reverse speed, the yoke 9 moves backward together with the shift shaft 4, and the dog 12 also moves backward. Regulation dog 1 meshing with dog 12
3 can be axially displaced rearward, so it retreats as one piece. Therefore, the shift to reverse speed can be performed without any problem.

Contrary to the above, when shifting to 5th gear, the yoke 9 moves forward together with the shift shaft 4, and the dog 1
2 also moves forward. At this time, the regulating dog 13 is locked by the stopper hole 15 and the pin 17 and cannot move forward, so that the regulating dog 13 is disengaged from the dog 12. As a result, the regulating dog 13 is swung in the opposite direction by the angle θ by the spring 18 and returns to its home position (return position).
Therefore, the regulating dog 13 and the dog 12 are displaced by an angle θ in the circumferential direction, so that the tips of the teeth overlap and face each other (FIG. 5). The above state is maintained while the vehicle is running in fifth gear.

Next, when the shift lever is returned to the intermediate position in order to change gears from 5th gear, the yoke 9 moves backward, and at this time, the dog 12 and the regulation dog 13 have their tooth tips facing each other and do not mesh, so the regulation dog 13 is pushed backwards. At this time, the regulation dog 13 can be moved back from its home position by the shift stroke using the stopper hole 15 and the pin 17, so the yoke 9 moves back without any obstruction, the shift shaft 4 returns to the intermediate position, and the fifth gear shift is released. .

If you try to shift to reverse speed directly from this state, that is, by carelessly operating the shift lever without changing the select position, the restriction dog 13 will prevent further backward movement by the stopper hole 15 and pin 17. Accordingly, the yoke 9 and the shift shaft 4 are prevented from moving backward, and in this case, the shift to the reverse speed is prevented.

When the shift operation of the shift lever 1 is performed to release the 5th gear shift, and then the selection is changed, the shift lever tip 1a comes out of the locking groove 8, and at the same time, the yoke 9 is reversed in the θ angle by the spring force of the spring 10. Shake and return to a fixed position. When the yoke 9 returns to the fixed position, the dog 12 meshes with the regulating dog 13 again, and in this engaged state, the regulating dog 13 slides under the force of the spring 18 and can return to the fixed position. This restores everything to its original state and prepares it for the next operation.

As described above, the shift operating device for an automobile transmission of the present invention has a yoke having a locking groove pivoted on a shift shaft that combines forward speed and reverse speed, and when selected, this yoke oscillates at a certain angle. At the same time, a certain rule is given by combining a dog integrated with this yoke and a regulating dog, so that when the shift shaft is directly shifted from forward speed to reverse speed, both dogs The gears are designed to wrap around each other to prevent this movement, thereby preventing the erroneous operation that tends to occur when shifting gears while driving, such as shifting carelessly in a straight line from a certain forward speed to a reverse speed at the same select position. be able to. Shifting to regular reverse gear can be performed smoothly without the need for additional operations such as levers or buttons, improving overall shift lever operability.
Moreover, since it is operated by a dog that is pivoted on the shift lever, it has a simple and compact structure and can be easily incorporated into the converging gear shift operation mechanism, which is highly effective in terms of function and cost. It is something.
