  • Patent number: 9440625
    Abstract: A parking lock arrangement for a motor vehicle transmission has a blocking arrangement actuatable between a release position and a blocking position. The blocking arrangement is designed to immobilize a motor vehicle in the blocking position. The parking lock arrangement has an arrangement for actuating the blocking arrangement. The actuating arrangement has a cam disc supported on a housing and driveable for rotation and has an actuating cam portion that extends over a first circumferential region of the cam disc that is greater than 5° and less than 180°. The actuating arrangement has a lever supported pivotably on the housing and coupled to the blocking arrangement. The lever is connected to a driving feature that is coupled to the cam disc, such that, when the cam disc is rotated, the driving feature is taken along by the actuating cam portion in such a way that the lever is pivoted in order to actuate the blocking arrangement.
