  • Publication number: 20190128411
    Abstract: An electrohydraulic actuator for a hydrostatic transmission includes a pair of pressure control valves between a hydraulic pressure inlet line and a pair of passages to a cylinder. A piston is positioned in the cylinder between the pair of passages and is slidable in response to hydraulic pressure in the cylinder on each side of the piston. A piston rod connects the piston to a joint which is connected to the trunnion lever of the hydrostatic transmission. A pedal position sensor provides electrical signals to an electronic controller that selectively actuates the pair of pressure control valves.
