Parking Lock

Parking Lock







Even if the vehicle is in gear, it cannot be prevented from rolling back in the same way as with a manual transmission because the clutches are opened in a depressurized state and thus do not stop the vehicle from moving. The parking lock prevents the vehicle from rolling away, as with an automatic transmission. When the vehicle is stationary, the parking lock is engaged (purely mechanically) using a selector lever and blocks the rear axle shaft via a stop which engages in the splines of the parking-lock gear. In this way, the connecting shaft that is driven via the rear axle shaft is blocked.

The pawl is positioned by the connecting shaft in the guide bush. If the parking lock is engaged using the selector lever, the pawl pushes the stop out of its neutral position against the parking-lock gear. The stop engages in the splines of the parking-lock gear and blocks the rear axle shaft. When the parking lock is disengaged, the pawl is pulled back out of the guide bush and the stop can occupy the unlocked position again through the spring force of the spring.
