ABSTRACT:
This invention is concerned with vehicle transmission systems of the kind which include at least one transmission drive shaft, at least one motor generator and at least one planetary gear means comprising a planet gear, sun gear and an outer ring. The motor generator engages the sun gear through the intermediary of a gear transmission assembly and the relative speed between the outer ring and the drive shaft is controlled by supplying energy to and taking energy from the motor generator. The sun gear is rotatably journaled on the drive shaft, and the drive shaft is connected rigidly to the journalling points of the planet gears. The primary force is transmitted from the motor generator to the outer ring of the planetary gear means through the intermediary of a force transmission gear. As a result of this arrangement, when the sun gear is retarded by the motor generator, through the gear transmission assembly, the journaling points of the plant gears will rotate around the gear center and drive the drive shaft, irrespective of retardation of the sun gear.
