1. A drive device for road wheels of a vehicle, the drive device comprising:
a stationary housing (1); a rotatably drivable differential housing (3) with an axle differential gear unit, the rotatably drivable differential housing (3) being rotatably mounted in the stationary housing (1) by differential bearings (2); at least one driveshaft (4) rotatably drivable by the rotatably drivable differential housing (3); at least one driving gear wheel (5) associated with and arranged on the at least one driveshaft (4), so as to be fixed with respect to rotation relative to the driveshaft (4); and at least one driven gear wheel (7), the at least one driving gear wheel (5) meshingly engaging, by oppositely directed helical teeth, with the at least one driven gear wheel (7) 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, the at least one thrust bearing arrangement being in turn supported at a structural component part of the drive device, wherein the at least one thrust bearing arrangement comprises a stop disk (13) secured to the differential housing (3), or to a structural component part connected to the differential housing, the stop disk (13) axially contacting, by its radial first side (26), the at least one driving gear wheel (5) and, by its radial second sides (27), parallel to their radial first sides (26), the stop disk (13) is directly or indirectly supported axially with respect to the at least one driveshaft (4) at a radial supporting surface (17) of the differential housing (3) or of the structural component part connected to the differential housing. |
