ABSTRACT:
A drive axle has a drive motor and two reduction gearsets located on the ends of the axle to drive respective wheels. The input stages of the reduction gearsets are formed as common single-stage planetary gear train. The planetary gear train is connected to the final stages of the reduction gearsets by respective output shafts. The planetary gear train has a rotatable sun wheel, a rotatable planet carrier and a rotatable ring gear. In one embodiment, the sun wheel of the planetary gear train is in a drive connection with an input shaft, and the planet carrier is connected to a first output shaft, and the ring gear of the planetary gear train is connected to a second output shaft. The output shafts are each formed as a sun wheel of the reduction gearsets. The output of the first reduction gearset is via the planet carrier and the ring gear of the first reduction gearset is stationary relative to the axle housing. The output of the second reduction gearset is by the ring gear, and the planet carrier of the second reduction gearset is stationary relative to the axle housing.
