Drive Device For The Road Wheels Of A Vehicle

摘要

A drive device for the road wheels of a vehicle, with a stationary housing partially filled with a lubricating liquid, and a rotatably drivable driveshaft inserted into the housing interior and with a differential unit having a crown wheel with a differential housing. The crown wheel is rotatably drivable by the driving gear wheel, by means of which crown wheel a plurality of differential gear wheels of the differential unit are rotatably drivable, driven gear wheels being rotatably drivable in turn by these differential gear wheels. The driven gear wheels being drivingly connected in each instance to driven shafts for driving the road wheels of the vehicle. The differential unit is enclosed in the housing interior by a shielding housing, wherein the stationary housing interior is connected to the shielding housing interior via one or more apertures.
