For OEMs that build on-road and off-road mobile machinery, a hydrostatic transmission should be considered versus a standard gear transmission because of the seamless way speed ratios and torques can be achieved. A hydrostatic transmission is made up of a hydraulic pump connected (and dedicated) to one or more hydraulic motors. By making either or both of these pump and motors variable displacement, it allows for a continuously variable transmission. As part of this closed loop hydraulic circuit, a charge pump is needed.
