Hydrostatic transmission
A hydrostatic transmission having a pump and a hydraulic motor which are in communication with each other through a fluid passage and each of which has one of an eccentric and inclined movable member that is moved to vary the volume of liquid discharged by the pump or motor, wherein the pump is driven by an input rotation and the motor provides an output rotation of a varied rotational frequency is described comprising: a first means for urging the movable member of the pump in a first direction; a second means for urging the movable member of the motor in a second direction; and an actuating rod disposed between the movable members and operatively contacting the movable members of the pump and motor, which actuating rod moves the movable member of the pump a distance proportional to a control input thereto, and which, when the displacement of the pump is varied, retains the movable member of the motor to keep the displacement of the motor constant. When the movable member of the pump is retained at a certain constant displacement position, moves the movable member of the motor a distance proportional to the control input.
