A power transfer unit assembly for a vehicle. The power transfer unit includes a housing, an internal variable speed differential positioned within the housing, a first front side shaft rotatively connected to the differential, a second front side shaft rotatively connected to the differential, an input shaft interconnected to at least one of the first and second side shafts, and at least one shifting mechanism for engaging at least one of the first and second shafts with at least one mode selection gear set. Engagement of the mode selection gear set transfers torque through the input shaft to selectively engage with a second gear set interconnected to a power transfer final drive unit assembly having an internal variable speed differential.

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.

A drive assembly for a multi-axle driven motor vehicle is disclosed herein. The drive assembly comprises a differential unit having a rotational axis, an input part and two output parts drivably connected to the input part, an externally controllable selectable coupling, and an externally controllable locking coupling. The output parts have a compensating effect among each other. The externally controllable selectable coupling is for drivably connecting the differential unit to a drive source. The externally controllable locking coupling is for locking the compensatory movement between both output parts of the differential unit.
