HYDROSTSTIC TRANSMISSION FOR MULTIPURPOSE VEHICLE

摘要

A hydrostatic transmission for multipurpose vehicle is provided to control the traveling of the vehicle and the operation of working equipment at the same time and to remove transmission shock. A hydrostatic transmission for multipurpose vehicle comprises an engine(10), a hydraulic pump(20), a key solenoid valve(30), an acceleration solenoid valve(40), and a working equipment driving part(50). The engine varies in rpm corresponding to the acceleration amount of the vehicle. The hydraulic pump is driven by the engine. The key solenoid valve is connected to the hydraulic pump, and operates to let the flow of the hydraulic pump in when the vehicle starts. The acceleration solenoid valve is connected to the key solenoid valve, and operates to let the flow from the key solenoid valve in a hydraulic motor(200) when a vehicle accelerator(100) is stepped on. The working equipment driving part is connected to the hydraulic pump, and operates to drive working equipment of the vehicle.
