An electric axle drive unit for an axle of a vehicle has an electric machine. The drive output of electric machine can be connected to the input of a transmission device. The electric drive unit has a differential gear, the input member of which is connected to an output of the transmission device. The output members of the differential gear can be connected respectively to a left-hand and a right-hand driveshaft of the axle. At least one transmission stage of the transmission device and the differential gear are arranged on opposite sides of the electric machine in the axial direction. The differential gear is connected to the transmission stage by means of a hollow shaft.

Electric axle drive unit

An electrical synchronous machine, in particular for use as a drive machine in motor vehicle applications. A stator has an electrical winding arrangement for generating a rotating field. A rotor has magnetic flux generating means for generating a rotor flux with which the rotating field interacts. The rotor has a first rotor section with first magnetic flux generating means and a second rotor section with magnetic flux influencing means. It is possible to move the two rotor sections relative to one another between at least a first and a second relative position in such a way that the rotor flux provided by the rotor has a different magnitude in the two relative positions.
