Parking Lock



Parking Lock

Even if the vehicle is in gear, it cannot be prevented from rolling back in the same way as on a manual transmission because the clutches are opened in a depressurized state and therefore 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 the selector lever and blocks the pinion shaft via a catch, which engages in the toothing of the parking-lock gear. The final drive is blocked in this way.
