GROUPE DE TRACTION TANDEM A REDUCTEURS ET VEHICULE A TRACTION ELECTRIQUE OU HYBRIDE COMPORTANT UN TEL GROUPE

摘要

The traction unit has two motor-reduction gear units (4-7, 14-17) each comprising an electric motor and a speed reduction gearbox. The input shaft to the reduction gearbox is parallel to the output shaft from the reduction gearbox, but separated by a short distance. The two reduction gearboxes are placed on either side of a median plane (24). The electric motors lie to the other side of the median plane from the gearbox. The two electric motors are not mutually aligned. The electric generators that supply the motors are placed facing one of the motors, on the other side of the median plane to that motor.
