Abstract
A hydrostatic transmission including a hydraulic pump, a hydraulic motor, and an external manifold surrounded by and in contact with air for connecting the hydraulic pump and a hydraulic motor. The external manifold facilitates heat transfer from hydraulic fluid flowing therein to the surrounding air. The design of the hydrostatic transmission with external manifold also allows virtually any desired relative orientation of the pump and motor to be achieved by only changing the shape of the manifold.
