Abstract:
A drive assembly for a motor vehicle driven by a plurality of axles includes 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 that is rotatably drivable around an axis of rotation, and two output parts drivingly connected to the input part. The hang-on coupling drivingly connects the differential unit and a driveshaft. The 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. The first hydraulic actuating unit, the hang-on coupling, the second hydraulic actuating unit and the locking coupling are arranged coaxially relative to the axis of rotation.
