PARK PAWL WITH ACTUATOR

摘要

A motor vehicle 10 includes a hydromechanical powersplit transmission 11 having an output shaft 63 extending between a planetary gear set 71 and vehicle drive wheels 15. The transmission 11 includes a housing 29 and a park pawl assembly 120 in the housing 29. The park pawl assembly 120 selectively locks the output shaft 63 to the housing 29 to prevent unintentional movement of the vehicle 10 such as when the vehicle 10 is parked. The park pawl assembly 120 includes a park pawl 122, a park pawl actuator 127, and a park pawl release arm 133. A locking spring 132 biases the park pawl actuator 127 to a locked position. Rotation of the release arm 133 causes substantially straight line movement of the park pawl actuator 127, which in turn causes rotational movement of the park pawl actuator 127 to an unlocked position.
