  • Park lock mechanism
    Patent number: 9920834
    Abstract: A park lock having an actuator assembly for pivoting a pawl relative to a dog ring. The actuator assembly has a first linear actuator, a locking mechanism, a first biasing spring and a second linear actuator. The first linear actuator has a first output member that is movable along a movement axis that is parallel to a pivot axis of the pawl. The locking mechanism is configured to selectively couple the first output member and a cam for common movement along the movement axis. The first biasing spring is configured to move the cam along the movement axis relative to the first output member when the locking mechanism decouples the cam from the first output member. The second linear actuator is configured to move the cam along the movement axis and against the first biasing spring when the cam is decoupled from the first output member.
