ABSTRACT:
A driving axle for a vehicle driven by an electric motor disposed on a driven motor shaft. Drive shafts are coupled to the motor shaft via the interposition of a reduction transmission stage and a following differential transmission. As part of the transmission stage an externally toothed sun pinion is disposed on the motor shaft, which is mounted in motor shaft bearings connected to a gearbox and absorbing radial and axial forces. A sleeve is disposed between, and supported on opposite sides against, the motor shaft bearings and sun pinion. A securing device is disposed on the free end of the motor shaft for fixing the sun pinion against the sleeve. Gears of the transmission stage mesh with the sun pinion, which together with the gears are embodied as helical gears having a force component acting in the direction of the motor shaft bearings.
