1. Normal operation mode (R↔N↔D)

In the general reverse (R) ↔ neutral (N) ↔ driving (D) operating conditions, as shown in Figures 3 and 4, the mode switching pin (9) is the operation plate 31 when moving the shifting lever (1) Since it is connected to the groove 43 formed in the operation force of the lever is immediately transmitted to the operation plate 31 to operate the detent plate 33 through the control cable 45 to form a hydraulic pressure suitable for the desired speed change stage.

In this mode, the first lever 17 and the second lever 25 are not connected to the upper locking pin 5 and the lower locking pin 7.

2. Reverse (R) range ↔ Parking (P) range

When switching the mode from the R range to the P range, first, the shift lever 1 is pushed to the left. Thus, when the lever is moved to the neutral position, as shown in FIG. 5, the pivot lever 1 moves by the pivot lever. At the same time as the lower locking pin 7 is engaged with the connecting hole 21, the mode switching pin 9 is released from the groove 43, and then the lever is switched from the neutral position to the P position for the parking operation. As shown in the drawing, the second lever 25 is rotated counterclockwise to push the operation plate 31 through the second rod 37 to transmit the operating stroke to the detent plate 33 to form a hydraulic pressure suitable for parking. In this mode, the first lever 17 operating in the D range is not connected.

That is, the rotation position of the shift stage is controlled by the second lever 25 connected to the lower end of the lever and the second rod 37 connected thereto while the mode switching pin 9 and the recess 43 are released. Done.

3. Driving (D) range ↔ parking (P) range

When switching the mode from the D range to the P range, first, the shift lever 1 is pushed to the left. When the lever is switched in this way, as shown in FIG. 7, the upper locking pin is moved by the pivoting movement of the shift lever 1. At the same time as 5 is engaged in the connection hole 11, the mode switching pin 9 is disengaged from the groove 43, and when the lever is operated to the P position for the parking operation, the first switch as shown in FIG. The lever 17 is rotated in the clockwise direction to push the operation plate 31 through the first rod 35 to transfer the operation stroke to the detent plate 33 to form a hydraulic pressure suitable for parking, in this mode R range The second lever 25 which is operated at is not connected.

That is, the rotational position of the shift stage is controlled by the first lever 17 connected to the upper end of the lever and the first rod 35 connected thereto while the mode switching pin 9 and the recess 43 are released. R2 is set to compensate for strokes in the R and N ranges so that the stroke direction can be maintained without changing the structure of the automatic transmission.
