IN-WHEEL ELECTRIC MOTOR MAINTENANCE INTEGRATION

The present invention relates to a rotor-stator combination for an in-wheel electric motor assembly of a vehicle, the in-wheel electric motor assembly comprising a bearing system (10) mounted to a knuckle of the vehicle for rotatably coupling a wheel rim to the knuckle of the vehicle, a brake, and the rotor-stator combination comprising a rotor and a stator, wherein rotor and stator are arranged concentrically with respect to each other such that rotor and stator share a common motor axis, and wherein the rotor-stator combination has a first axial end facing the vehicle knuckle in a fully assembled state of the in-wheel electric motor assembly and a second axial end facing away from the vehicle knuckle in a fully assembled state of the in- wheel electric motor assembly, wherein the stator comprises stator mounting points for mounting the rotor-stator combination to the vehicle knuckle, wherein the rotor-stator combination has a hollow interior adapted to receive the bearing system and the brake in a fully assembled state of the in-wheel electric motor assembly, and wherein the rotor comprises a plurality of rotor fixation holes and the stator comprises a plurality of stator fixation holes, wherein the rotor is lockable to the stator such that the concentric arrangement of rotor and stator is maintained without a bearing being arranged between rotor and stator, wherein locking the rotor to the stator is achievable by inserting a plurality of locking tools into the plurality of rotor fixation holes and into the plurality of stator fixation holes, wherein each of the plurality of locking elements is inserted into one of the plurality of rotor fixation holes and into a corresponding one of the plurality of stator fixation holes. According to the present invention, an opening of the rotor-stator combination at the first axial end of the rotor-stator combination facing the knuckle and leading into the hollow interior of the rotor-stator combination is designed such that the rotor-stator combination can be mounted to and dismounted from the vehicle knuckle as a unit without the need to remove the bearing system and/or the brake from the vehicle knuckle, wherein the stator mounting points are arranged at such a distance from the motor axis that the stator mounting points do not interfere with the bearing system and brake when the rotor-stator combination is mounted to or dismounted from the vehicle knuckle.
