Electric axle drive for a vehicle wheel axle

Abstract

An electric axle drive comprises a gear assembly having a first planetary gear set and a second planetary gear set. The gear assembly further comprises a spline ring that is provided with internal splines along an axial direction of the spline ring and that is slidably provided over ring wheel of the first planetary gear set having mating splines on its outer surface. The spline ring comprises an external groove along its circumference, for receiving a first shift actuator element to shift the spline ring in axial directions over the ring wheel. The spline ring further comprises a first interlock profile on one axial side, that locks the spline ring to a corresponding profile provided onto the stationary housing. The spline ring comprises a second interlock profile on an another axial side, that locks the spline ring, when slid by the actuator element to a corresponding profile provided on the carrier.
