Abstract
A drive device for a vehicle axle of a two-track vehicle, which has an axle differential, the input side of which is drivingly connected to an electric machine and the output sides of which drive on flange shafts leading to the two vehicle wheels. The vehicle axle has a superposition gear with a multi-disk clutch on each side of the vehicle, by which the electric machine can be connected directly to the vehicle wheel flange shaft by bridging the axle differential. The multi-disk clutches can be controlled by a control unit. On each side of the vehicle the multi-disk clutch is assigned a multi-disk brake acting as a vehicle wheel brake, by which vehicle braking processes can be carried out alternatively or in addition to the multi-disk clutch.
