  • Park lock mechanism
    Patent number: 9394993
    Abstract: A park lock having a cam that is movable along a movement axis to cause corresponding pivotable movement of a pawl relative to a dog ring. The park lock mechanism includes a first actuator assembly and a second actuator assembly. The first actuator assembly has a first output member on which the cam is slidably mounted. The second actuator assembly includes a detent mechanism, which is configured to resist movement of the cam relative to the first output member, and a biasing element that is configured to store energy. Operation of the detent mechanism to permit movement of the cam relative to the first output member employs the stored energy in the biasing element to translate the cam on the first output member.

  • Park lock mechanism
    Patent number: 9353859
    Abstract: A park lock mechanism having first and second actuator assemblies for selectively moving a cam against a cam follower to engage a pawl to a dog ring. The first actuator assembly can be selectively operated to coordinate movement of the cam between first and second cam positions. The second actuator assembly can be selectively operated to drive the cam from the first cam position to the second cam position.
