ABSTRACT:
In a hydromechanical transmission, low and high speed drive power trains are selectively completed in response to variation of the speed ratio between an input shaft and an output shaft. The transmission comprises a speed ratio detecting valve for detecting lower and higher limits of a predetermined speed ratio and a clutch control valve for conducting the switch over between the low and high speed drive power trains when the actual speed ratio reaches a range defined by the lower and higher limits of the predetermined speed ratio.
