Performance Investigation Of A Proportional Valve Controlled Hydraulic Motor Used In Hydrostatic Transmission System

The hydrostatic transmission systems (HST) are one of the well known and widely acceptable transmission systems. The main purpose of a HST system is to transfer the mechanical input power as a mechanical output power, using a hydraulic system consisting of a hydraulic pump and a motor. This paper concerns an investigation of the performance of a proportional valve controlled hydraulic motor used in hydrostatic transmission system. Various leakage flow and torque losses of the bent-axis hydraulic motor are to be represented as motor parameters like pressure, flow rate. The corresponding losses coefficients are to evaluated and validated experimentally. Various experiments have also been conducted extensively to determine optimum performance of the system.
