摘要：
Provided is a hydrostatic transmission including a pump/motor module having a reservoir housing and a hydraulic pump and motor disposed in the reservoir housing, and a speed reduction module having a speed reduction housing coupled to the reservoir housing and a speed reduction assembly disposed in the speed reduction housing. The speed reduction assembly includes an input member driven by the output shaft of the hydraulic motor, an output member rotationally connected to the input member by one or more belts/chains, and an axle shaft driven by rotation of the output member. By providing the speed reduction assembly in a separate housing from the hydraulic fluid in the reservoir housing, the speed reduction assembly is isolated from the hydraulic fluid thereby preventing particulates from the speed reduction assembly from entering the hydraulic fluid in the reservoir housing.
