Abstract
An electric vehicle which has motor wheels of the direct-drive outer-rotor type which permit simplification and compaction of the motor wheels. Current regulating covers introduce ambient air for cooling the motors and reduce air resistance, and batteries and control devices are disposed symmetrically relative to the axial line of the vehicle body and to axial lines of the axles so as to reduce and uniformly distribute the weight of the vehicle. All these devices contribute jointly to increasing the range of the electric vehicle.
Claims5
An outer-rotor type motor wheel, comprising:
- a knuckle, a hub coaxially interlocked with said knuckle, a wheel disc rotatably attached to the periphery of said hub, a wheel secured to the periphery of said wheel disc, a rotor fastened to an outer side of said wheel disc from the direction of said outer side, and a stator coaxial to and spaced from said rotor by a small gap and fastened to said hub from said direction of said outer side.
