Apparatus for fixing and driving a displacement member (such as a wheel) of a vehicle is disclosed. In particular, an axle journal is coupled to the vehicle chassis. At least one rotating bearing surface is disposed between the displacement member and the axle journal for the rotatable assembly of the displacement member. A drive motor is provided having a stator which is removably attached to the axle journal and a rotor which is removably mounted to rotate with respect to the stator by means of rotating bearings in contact with the bearing surface. Since the rotating bearings of the motor only contact the removable bearing surface, the motor can be dismantled while maintaining the displacement member in place on the axle journal.
