Abstract
An infinitely variable transmission for use with an internal combustion engine is provided. Specifically, a prime mover is provided for driving a first hydraulic machine. The first hydraulic machine is arranged to drive a second hydraulic machine via a fluid line that connects the first and second hydraulic machines. The second hydraulic machine is operatively connected with an output element, such as a wheel to drive a vehicle. Each of the first and second hydraulic machines have electronically controllable valves for varying the speed and/or the torque of the first and second hydraulic machines thereby providing an infinitely variable transmission.
