Abstract

A drive assembly for a motor vehicle, having two drivable axles, a first axle being driven permanently by a drive unit and at least a second axle being connectable via a double coupling assembly so as to be externally controllable. The double coupling assembly comprises a common drivable coupling carrier with outer plates and individual sets of inner plates each connected to the axles of the second driving axle. The double coupling is actuated by a common actuating device, thereby permitting both sets of plates of the double coupling to be loaded by the same amount of actuation forces.
