Abstract
The invention relates to a drive assembly for a four wheel drive vehicle with the distributor assembly for distributing driving torque arranged between the front wheels and the rear wheels of a driving axle. A distributor differential (13) and axle differential (15) distribute the driving torque. Both the distributor differential (13) and the axle differential (15) may be at least partially locked via viscous couplings (39, 40) in order to cancel the differential function. I order to achieve the shortest possible design, the two viscous couplings (39, 40) are arranged coaxially one inside the other.
