The drive module (5, 6) has a first shaft (19) rotatably supported relative to a stationary housing (18); a second shaft (22) which is drivingly connected to the first shaft (19); and a transmission stage (25) arranged in the torque flow between the first and second shafts (19, 22). The transmission stage (25) has at least one planetary gear (27) and a rotating carrier element (32). A coupling (37) serves to couple the carrier element (32) relative to the housing (18). When coupled, torque transmission occurs from one of the first or second shaft (19, 22), to the other one of the two shafts. The housing (18), the first shaft (19), the second shaft (22), the transmission stage (25) and the coupling (37) form part of a unit adapted to attach to a drive (3).

A parking lock assembly for a motor vehicle is described that has at least one electrically drivable driving axle. The parking lock comprises an electric drive, a shaft which is arranged in the driveline of a motor vehicle and which is drivable by the electric drive, as well as a locking mechanism which is controllable in the locking sense in order to prevent a rotational movement of the shaft and which is controllable in the opening sense in order to release the shaft. The electric drive is controllable in order to transmit torque to the shaft if, in spite of the locking mechanism being controlled in the opening sense, the shaft is prevented from carrying out a rotational movement. Furthermore, a method of actuating such a parking lock assembly is described.
