Motor in wheel electric drive system

摘要

A driving or driven wheel assembly for a vehicle includes a wheel having a rotor which has an inner surface coaxial with the axis of rotation of the wheel and a stator which form part of the axle structure. A portion of the stator is encircled by the rotor and an electrical coil connected to a source of electrical energy for creating an electromagnetic force to rotate the rotor relative to the stator. The stator is coupled to the wheel radially outwardly from the axis of rotation and orbits about the inner surface of the rotor via a trunnions mounted shaft. The shaft is driven into orbiting rotation and is coupled to the wheel chassis such that as the shaft orbits the chassis moves in response thereto while maintaining its spatial relation thereto.
