Abstract

A parking lock actuator includes a blocking cam, an actuating device, an energy store, a blocking drive, and an intermediate element. The blocking cam is arranged for positive engagement with a tooth gap of a parking lock gear and the actuating device is for transferring an actuating force to the blocking cam. The energy store is for transferring the actuating force from the actuating device to the blocking cam, the blocking drive is for displacing the actuating device, and the intermediate element is freely displaceable relative to the blocking drive over a predetermined intermediate path for displacing the actuating device. The blocking cam is arranged to positively engage the tooth gap to block rotational movement of the parking lock gear when the actuating device is in a blocked position, and the parking lock gear is rotatable when the actuating device is in an open position.
