Abstract

A drive device for the road wheels of a vehicle includes a stationary housing in which a rotatably drivable differential housing having an axle differential gear unit is rotatably mounted by differential bearings, at least one driveshaft being rotatably drivable by the differential housing. At least one driving gear wheel is arranged on the at least one driveshaft so as to be fixed with respect to rotation relative to the latter. The at least one driving gear wheel meshingly engage by oppositely directed helical teeth with at least one driven gear wheel for driving road wheels of the vehicle and generating axial forces directed toward the center of the axle differential gear unit. At least one thrust bearing arrangement is supported axially with respect to the at least one driveshaft at a radial supporting surface.
