Abstract

A drive device for a vehicle axle, especially a rear axle, of a two-track vehicle, wherein the vehicle axle includes an axle differential, which can be connected at the input end to a primary drive machine and can be connected at the output end across flange shafts arranged on either side to vehicle wheels of the vehicle axle, wherein the vehicle axle is associated with an additional drive machine and a shiftable superimposing gear, which can be shifted to a torque distribution gear in which a drive torque is generated by the additional drive machine, a torque distribution on the two vehicle wheels can be changed depending on the magnitude and direction of rotation of the drive torque, and shifting can be done to a hybrid mode in which the drive torque generated by the additional drive machine can be coupled to both flange shafts of the vehicle wheels.
