    Abstract: The disclosure relates to a drive assembly for a motor vehicle driven by a plurality of axles. The drive assembly comprises a differential unit, an externally controllable hang-on coupling, an externally controllable locking coupling, a first hydraulic actuating unit, and a second hydraulic actuating unit. The differential unit includes an input part which is rotatably drivable around an axis of rotation A, and two output parts which are drivingly connected to the input part. The two output parts have a differential effect relative to one another. The externally controllable hang-on coupling drivingly connects the differential unit and a driveshaft. The externally controllable locking coupling locks the differential movement between the two output parts of the differential assembly. The first hydraulic actuating unit actuates the hang-on coupling and the second hydraulic actuating unit actuates the locking coupling.
