HYDROMECHANICAL TRANSMISSION

摘要

The invention relates to a hydromechanical transmission which comprises a train of planetary gears which transmits the power from a driving shaft (A) to two driven shafts (B, C), one of them (C) actuating a pump (D). By means of a throttle valve (E), the rotation of the pump is partially or totally limited, thereby regulating the rotation speed of the output shaft (B), from zero speed up to a preset maximum speed. It can also be used as speed variator, security brake and clutch.
