An electromechanical parking lock for a motor vehicle includes a locking element for reversible engagement in a parking lock wheel, an actuating element that can be pre-loaded by an actuating spring in order to insert the locking element into the parking lock wheel, an electric motor with an actuating unit for moving the actuating element out of the locked position (P) against the spring force of the actuating spring into an unlocked position (nP), and a solenoid that, in the unlocked position (nP), holds the actuating element pre-loaded via a securing element. The parking lock has an emergency locking position (Not-P) in which the parking lock is unlocked and in which the securing element can be released by the electric motor without changing the state of the solenoid so that the locked position (P) can be assumed.

Parking lock for a motor vehicle and method for operating a parking lock

A parking lock has a parking lock housing (), a locking pawl () which has a ratchet () that can be locked in a parking lock wheel () and a pawl profile () arranged on the rear side of the ratchet (), an actuating unit () which acts upon the pawl profile () when the parking lock () is engaged and thereby rotates the locking pawl () about a rotational axis () relative to the parking lock housing (), and a supporting element (), on which the actuating unit () is supported in the engaged state (P) and in the disengaged state (nP) of the parking lock () at different positions. The supporting element () is connected to the parking lock housing () so as to have play.
