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.

Abstract: The invention relates to a drive assembly for a motor vehicle with a drive unit and multiple driven axles. The drive assembly comprises a transfer case 12 which distributes torque introduced by the drive unit 4 to a first driveline 5 and to a second driveline 7, wherein the first driveline 5 is permanently drivingly connected to the transfer case 12 in order to transfer torque to a first driving axle 6 and wherein optionally, in addition to the first driveline 5, the second driveline 7 can be drivingly connected to the transfer case 12 in order to transfer torque to the second driving axle 8, and a propeller shaft 24 which is arranged in the torque flow between the transfer case 12 and the second driving axle 8, wherein there are provided first coupling means 22 for coupling and uncoupling the propeller shaft 24 relative to the drive unit 4, as well as second coupling means 26 for coupling and uncoupling the propeller shaft 24 relative to the second driving axle 8.
