Abstract

The present disclosure describes a parking lock gear mechanism including a planetary gear train with a sun gear, a ring gear, and at least one planet gear that meshes with the sun gear and the ring gear. The at least one planet gear may be attached to a rotating planet carrier. The parking lock gear mechanism may also have a spring unit coupled to the ring gear, where the spring unit is configured such that it is tensioned by a rotation of the ring gear, and exerts a torque and/or force on the ring gear when it is tensioned. A ring gear securing unit may be configured to secure the ring gear against rotation in a first operating state, and to release the ring gear such that it can rotate in a second operating state.
