Abstract

The disclosure relates to 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 at the output end to flange shafts arranged on either side with vehicle wheels of the vehicle axle, wherein the vehicle axle is associated with a shiftable superimposing gear, which can be shifted to a torque distribution mode by a torque distribution shift element, in which a drive torque generated by an additional drive machine in a first load path can be coupled to one of the flange shafts in order to change a torque distribution on the two vehicle wheels, and the drive torque generated by the additional drive machine can be coupled to the input side of the axle differential in a second load path.
