Abstract

PURPOSE: To stabilize and secure the control, by means of controlling the control elements by an actuating oil from two pumps which is drived by a driving system and a running system of a car.
CONSTITUTION: Branched pipings 21, 22 are connected to a delivery port 117 of a forced clutch off device CLO via a center actuating oil path 44 of a main servomotor MS fitted with a control valve, an opening/closing valve V, and an oil supplying path 118, and an oil supplying path 24 is passed through an oil path 25 in an input axis 3 of a stepless transmitter CVT, and an engine driving pump EP is connected to a main oil supplying path 20 which is connected to an oil pressure pump p and an oil pressure closing path of an oil pressure motor M via check valves 26, 27, and the opening/closing valve V which is controlled by a variable operating arm L, and a running driving pump VP which generates output oil pressure proportional to car speed to the forced clutch off device CLO is connected. By such means, the main servomotor MS fitted with a control valve MS, the opening/closing valve V, the forced clutch off device CLO and a stepless transmitter CVT are controlled by means of utilizing the actuating oil from both pumps EP, VP, and failsafe is constituted, thereby the control is performed safely and exactly.
