DRIVE DEVICE FOR THE ROAD WHEELS OF A VEHICLE

摘要

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.

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 is supported axially with respect to the at least one driveshaft (4) at a radial supporting surface (17) by supporting elements arranged at the housing (1) so as to be axially displaceable.
