A hydrostatic drive system for a mass transit vehicle includes an engine that drives a hydraulic pump. The hydraulic pump circulates high-pressure fluid through a circuit to two slave motors disposed at each driven wheel. The slave motors include a shaft rotated in proportion to the flow of fluid to drive a driven gear disposed on an axle supported by the frame of the motor vehicle. The hydrostatic drive transmits power from the engine through fluid pressure circulated by a hydraulic pump to the slave motors through a circuit composed of tubes or hoses. The tubes or hoses require little space compared to an axle assembly of a prior art inverted portal axle system.
A drive system for a motor vehicle comprising;
The drive system of claim 2, further including a forward hydraulic circuit and a reverse hydraulic circuit supplied with a flow of hydraulic fluid from said main hydraulic pump and in fluid communication with each of said first and second slave motors.
The drive system of claim 3, further including a control valve positioned to control a flow of hydraulic fluid to each of said first and second slave motors.
A method of controlling a hydrostatic drive system for a motor vehicle said method comprising the steps of;
