Propulsion system for a vehicle

Abstract

A propulsion system for a vehicle having a longitudinal axis comprising a single driving source having a driving shaft; a pair of driven elements, each of the pair of driven elements being spaced from and on opposite sides of the longitudinal axis; a first differential device having an input shaft coupled to the driving shaft and two output shafts; a second differential device having an output shaft coupled to one of the pair of driven elements, a first input shaft coupled to one of the two output shafts of the first differential device and a second input shaft coupled to the driving shaft; a third differential device having an output shaft coupled to the other of the pair of driven elements, a first input shaft coupled to the other of the two output shafts of the first differential device and a second input shaft coupled to the driving shaft; and a control arrangement coupled to the driving source, the first input shaft and the output shaft of the second differential device and the first input shaft and the output shaft of the third differential device to control the relative speed of each of the pair of driven elements to enable controlling the speed and maneuvering of the vehicle.
