Steering Lock Interlock

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

TASK
- To prevent the ignition key being removed when the parking lock is not engaged.

DESIGN
- The locking pawl (39) of the parking lock is cone acted 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 steering lock interlock is of the same design as the parking lock interlock and interacts with it

FUNCTION
- When the parking lock is not engaged and the brake pedal is not operated, the locking pawl (63) abuts the outer contour of the detent plate (38).

- The shift and locking valve (50) is held in position in front of the blocking cam (61) against the force of the pressure spring (62) via the control cables (53, 54). The ignition key can therefore not be turned to position "0".

- In selector position "P" and the rest position of the brake pedal the force of the tension spring (57) can pull the locking pawl (39) under the stop on the detent plate (38) and at the same time the pressure spring (62) pulls the shift and locking valve (60) off the blocking cam (61).

- The ignition key can now be turned to position "O" and removed.
