A drive device for a vehicle axle, in particular a rear axle, of a two-track vehicle with an electric drive, wherein an electric machine is associated with every vehicle wheel of the vehicle axle, the electric machine shafts of which electric machine can be drivingly connected, by a first and a second shifting element, to a first and a second flange shaft of the vehicle wheels, and wherein in a first transmission gear, the first and the second shifting element are shifted and the electric machine shafts output directly to the flange shafts of the vehicle wheels via the first and the second shifting element. The vehicle axle has a transverse differential which, on the output side, outputs to the flange shafts of the vehicle wheels and, on the input side, can be drivingly connected to the electric machine shafts by means of a third and a fourth shifting element.
