Abstract
A drive device for road wheels of a vehicle includes: a stationary housing; a rotatably drivable differential housing with an axle differential gear unit, the differential housing being rotatably mounted in the stationary housing by differential bearings; at least one driveshaft rotatably drivable by the rotatably drivable differential housing; at least one driving gear wheel associated with and arranged on the at least one driveshaft, so as to be fixed with respect to rotation relative to the at least one driveshaft; and at least one driven gear wheel, the at least one driving gear wheel meshingly engaging, by oppositely directed helical teeth, with the at least one driven gear wheel to drive the road wheels of the vehicle and generate axial forces directed toward the center of the axle differential gear unit, and having at least one thrust bearing arrangement configured to support the axial forces.
