Abstract:
A parking pawl actuation assembly for a transmission includes a shaft, a hub member rotatably supported by the shaft, a cam plate and lever plate rotatably supported by the hub member, a first resilient member disposed between the cam plate and the lever plate, and wherein the resilient member applies a rotational force on the cam plate in a first rotational direction when the lever plate is rotated in the first rotational direction, an actuator configured to selectively rotate the lever plate to one of a plurality of positions, and a parking pawl member configured to engage the cam plate and the parking gear of the transmission.
