ABSTRACT:
An electric wheel-drive for motor vehicles, particularly automobiles with internal combustion engine, which can be installed nondestructively-reversibly in place of the brakes, with brushless, polyphasic, electronically speed-controlled electric motors individually attached to the wheels. The electric motor is a homopolar multiple-airgap axial-field motor whose rotor (1) replaces the wheeldrum and brake-disk, and whose stator (2) replaces the brake-shoes, brake-pads, and brake splash-shield plate of at least two wheels of a pair, in a conventional automobile with internal combustion engine. An electronic control system is included for the control of the axial-field motor during propulsion and braking. This electric wheel-drive allows for a fast, uncomplicated, and inexpensive hybridization of the car without modifications of the wheels, or the axle, or of other parts of the car, thereby providing the car with second, independent, propulsion system.
