WHEEL ASSEMBLY WITH INTEGRAL ELECTRIC MOTOR

摘要

The subject invention provides a wheel assembly (20) having a spindle (26) for attachment to a vehicle along a rotational axis (R). An electric motor (22) is disposed radially about the spindle (26) and includes a stationary stator (34) and a rotor (36) rotatable about the rotational axis (R) relative to the stator (34). A rotor support (40) is disposed about the spindle (26) and includes a collar (42) rotatably supported by at least one rotor support bearing (46) on the spindle (26). The rotor support (40) includes a flange (44) disposed within a predetermined axial distance (D) and extending radially outward from the collar (42) to support the rotor (36). A planetary gear system (62) interconnects the rotor support (40) and a wheel drive (52) for reducing rotational speed of the rotor (36) and increasing the torque of the wheel assembly (20).
