Self frequency ramping alternating current wheel motor system for hybrid vehicles
Abstract:
A hybrid electric vehicle with two separate drive systems. High speed operation is powered by self frequency ramping alternating current motors 107 within the wheel rims. Low speed operation is powered by hydraulic motors 102 directly coupled to the drive wheels. The hydraulic oil is pressurized by direct current motors/pumps 302 & 309 energized by a battery pack 106. The alternating current motors 107 are energized by mechanical or electronically generated alternating current. The hybrid power source is either a combustion engine 406 driving a poly-phased alternator 501 or a fuel cell 600 providing direct current. In the case of the combustion engine 406, a direct current helper motor/generator 404 will augment the engine with power from the battery pack 106 under large demands and charge the battery pack 106 under small demands. In the case of a fuel cell 600, the cell is augmented by the battery pack 106 under large demands and charges the battery pack 106 under small or no demands.
