Abstract
A coupling assembly has at least one friction coupling unit which comprises a driveable housing and a hub to be driven, and having differential-speed-dependent actuating means operating by a pressure agent and comprising a pump unit. The pump unit comprises housing parts and hub parts, which housing parts are rotatable relative to said hub parts with the one part of the pump unit being connected in a rotationally fixed way to the housing of the friction coupling unit and the other parts of the pump unit being connected in a rotationally fixed way to the hub of the friction coupling unit. The hub of the at least one friction coupling unit is receiving an outer joint part of a constant velocity universal joint.
