ABSTRACT:
An integrated hydromechanical transmission capable of achieving continuous variability from maximum forward, through zero, to full reverse, and vice versa. The unit will achieve significantly higher rates of efficiency than current hydrostatic transmissions and, as well, has many other desirable characteristics. Intended for use in heavy-duty drive-wheel-steered and tracked vehicle applications such as hay windrowers, grain swathers, crawler tractors, military armoured vehicles, etc.
