ABSTRACT:
A parking lock mechanism for use in a vehicle drivetrain subassembly having an electric motor coupled to a reduction gear set with the gear set including a rotatable output member having a plurality of circumferentially spaced locking holes. The mechanism comprises a locking pin movably mounted in an end cover structure of the drivetrain subassembly and a cam rotatably mounted in the end cover structure and having an inner portion in contacting engagement with the locking pin. An actuator assembly is provided for applying a torsional load to the cam which urges the locking pin into contacting engagement with the output member when the locking holes are circumferentially misaligned with the locking pin and causes a predetermined rotation of the cam about its longitudinal axis from a released position to an actuated position when one of the locking holes is circumferentially aligned with the pin. The rotation of the cam to the actuated position forces the pin into a releasable locking engagement with the aligned one of the locking holes so as to prevent rotation of the output member of the vehicle drivetrain gear set.
