Vehicle transmission system
First Claim
1. A vehicle transmission system having a drive shaft or drive shafts which can be driven continuously at varying speeds, said system comprising a combination of at least one motor generator and at least one planetary gear means having an outer ring, a planet gear and a sun gear, wherein the motor generator engages the sun wheel through the intermediary of a gear transmission means;
- wherein the relative speed between said outer ring and said drive shaft or shafts is controlled by supplying energy to and taking energy from said motor generator;
wherein the sun gear is rotatably journaled to the drive shaft or shafts;
wherein said drive shaft or shafts is, or are, rigidly connected to the journal points of the planet gears; and
wherein a force transmission gear is provided for transmitting the primary force from the motor generator to the outer ring.

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.
