Abstract

A parking lock for a transmission of an electric or hybrid vehicle is disclosed. The parking lock includes a lock device including an actuatable actuating element and a setting element adjustable between a deployed position and a retracted position. The locking device is configured such that, in response to repeated actuation of the actuating element, the setting element is, via a coupling mechanism, adjusted alternately between the retracted position and the deployed position. A camshaft is provided with a cam arranged on the camshaft that is connected in terms of drive to the lock device. A ratchet wheel is provided with a pawl that is adjustable between an engagement position, where the pawl blocks a rotation of the ratchet wheel, and a release position, where the blocking of the ratchet wheel is released. The setting element adjusts the pawl between the engagement position and the release position.
