  • Publication number: 20120053002
    Abstract: 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. The selectable coupling and the locking coupling are arranged coaxially to the rotational axis.

  • Patent number: 8535194
    Abstract: A coupling assembly for optionally connecting a driving axle in a motor vehicle having multiple driving axles is disclosed. The coupling assembly comprises an externally controllable friction coupling with a coupling input part and an output part. The input part is rotatingly drivable around an axis of rotation A. A differential drive with an input element and two output elements which are drivingly connected to the input element, are also included. The input element of the differential drive is arranged coaxially relative to the coupling output part and drivably connected to the coupling output part for the purpose of transmitting torque. A driveline assembly having such a coupling assembly is also disclosed.

  • Patent number: 8668615
    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.
