초록 ▼

An electric drive propulsion system is composed of one or more series motor coupled directly to drive individual wheel axles of a vehicle, the motors being electrically connected directly to the output of a generator driven by the vehicle engine. A power switch is operated by the vehicle brake pedal to disconnect and connect excitation current to the generator to initiate and stop propulsion. Speed of propulsion is controlled by the accelerator pedal of the vehicle engine, the generator driven thereby providing the sole source of energy for the propulsion motors.

대표청구항 ▼

An electric drive propulsion system for a motor vehicle comprising: a vehicle having an engine for providing propulsion power thereto, including a vehicle engine accelerator, wherein rotational speed of said engine is controlled exclusively by said vehicle engine accelerator; an electric generator connected to said engine to be driven thereby, said generator including an exciting coil for causing electric energy to be generated upon excitation thereof, the exciting coil being connected for excitation to a source of DC current through a preset electric resistance adjusting device, such that electric energy output of said generator varies solely with variations of said engine rotational speed; at least one electric motor mounted on said vehicle and coupled with an axle thereof to drive the axle to provide propulsion for said vehicle, said at least one electric motor being directly connected to said generator by an electric circuit having no intermediate control devices so as to be driven solely by the entire electric energy generated thereby; said vehicle being provided with a brake and a brake pedal for operating said brake; a pair of normally closed contact terminals of a power switch connected in said generator excitation circuit between said exciting coil and said source of DC current, said power switch being operated by said brake pedal to open said contact terminals upon application of pressure to said brake pedal and to close said contact terminals upon release of said brake pedal, operation of said brake pedal thereby causing discontinuation of vehicle propulsion and release of said brake pedal causing continuation of propulsion; such that said at least one electric motor is connected to receive the entire output of electric energy generated by said electric generator as the sole source of energy for propulsion of said vehicle so as to increase and decrease speed of said at least one electric motor both in accordance with increase and decrease of speed of said engine as controlled by said vehicle engine accelerator and continuation and discontinuation of vehicle propulsion as caused by operation of said brake pedal.
