Drive device for a vehicle axle

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 two vehicle wheels, wherein 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 each vehicle wheel flange shaft by bridging the axle differential, wherein the multi-disk clutches can be controlled by a control unit for a redistribution of braking torque between the vehicle sides in a recuperation mode of the electric machine,

• wherein a multi-disk brake acting as a vehicle wheel brake is assigned on each side of the vehicle of the multi-disk clutch, by which vehicle braking can be carried out alternatively or in addition to the multi-disk clutch;
• wherein, on each side of the vehicle, both the multi-disk clutch and the multi-disk brake can be actuated via a common hydraulic cylinder which is connected to the control unit via exactly one hydraulic line, and in that the hydraulic cylinder builds up a hydraulic pressure when controlled by the control unit, with which a pressure element presses both against a disk pack of the multi-disk clutch and against a disk pack of the multi-disk brake.
