Parking Lock Interlock

LOCATION
- The parking lock interlock mechanism connects the parking lock in the transmission with the ignition lock via the brake pedal.

TASK
- To prevent an unauthorized release of the parking lock.

DESIGN
- The locking pawl (39) of the parking lock is connected to the release lever (56) at the brake pedal via a connecting rod and a control cable (54). At the same time there is a connection to the shift and locking valve (60) in the adapter housing (63) via the control cable (53). The shift and locking valve (60) is blocked by the blocking cam (61) in the steering lock (59).

- The parking lock interlock is of the same design as the steering lock interlock and interacts with it.

FUNCTION
- If the parking lock is engaged, the ignition key removed and the service brake not operated, the locking pawl (39j blocks the detent plate (38). The parking lock cannot be released.

- So that the parking lock can be released, the ignition key must be turned to position "1" and the brake pedal operated. From ignition key position "1" the blocking cam (61) in the steering lock releases the control cable (53). When the brake pedal is operated the locking lever (55) is turned downwards via the roller (58), the tension spring at the brake pedal is tensioned and the release lever (56) is released.

- The force of the pressure spring (64) now acts against the lower spring force of the pressure spring (62) via the control cables (53, 54) and pulls the shift and locking valve (60) in front of the contour of the blocking cam (61). At the same time the locking pawl (39) is turned via the connecting linkage and lifts off the detent plate (38).

- The parking lock can now be released.
