ABSTRACT:
A diesel motor-driven electric drive power train system including a diesel engine having a rotatable crankshaft from which a torquing force is output when the engine is energized; an electric generator having a rotatable rotor coupled to the crankshaft of the diesel engine and generating an output electrical current when rotated by the crankshaft; a vehicle frame coupled to the diesel engine and generator and having a wheel rotatably coupled thereto and with the wheel having a central axle shaft extended therefrom; an electric motor coupled to the axle shaft of the wheel for rotating the wheel when electrically energized; and a manually-actuatable three-position gear shift switch mechanism coupled between the generator and the motor and having a first position for energizing the motor to allow the wheel to turn in one direction, and a second position for energizing the motor to allow the wheel to turn in an opposite direction, and a third position for de-energizing the motor.
