<p>HYBROSTATIC TRANSMISSION A hydrostatic transmission in which a hydraulic pump and motor are in a generally U-shaped arrangement with a fluid transfer manifold extending between the pump and the motor. The pump is driven on one side of the manifold by the drive motor of the vehicle on which the transmission is used, and a drive wheels on the other side of the manifold, to power the drive wheels on the other side of the manifold. A housing surrounds the pump, motor and manifold and contains hydraulic fluid for the operation of the transmission. Servo controls for the pump and motor are located on the outside of the housing and a control cover has preloaded servo pistons which properly adjust the servo controls when the cover is attached to the housing. A charge pump for the servo controls is in the manifold, and rigid tubular conduits extend between the charge pump and the control cover. The conduits are mounted between, and held in place by, the charge pump and control cover, and require no hydraulic fittings or connections to secure them therebetween.</p> |
