<p>PURPOSE:To obtain the smooth operation of a clutch mechanism by controlling the oil quantity supplied from a master cylinder with high precision by driving a motor connected with the master cylinder through an encoder operated on the basis of the signal of an electronic controller. CONSTITUTION:The control signal supplied from an electronic controller is input into an encoder 2, and a motor 3 is turned in the counterclockwise direction. Then, a rod 8 is shifted leftward by an arm 5, and a working chamber 14 is cut from an oil tank 10 by a piston 12. Therefore, the pressurized oil in the working chamber 14 is sent into the working chamber 24 of a hydraulic actuator 21, and a piston 23 is pressed rightward, and a clutch lever 17 is turned in the counterclockwise direction. Further, the pressurized oil in the working chamber 24 is sent into the working chamber 33 of a hydraulic type air control valve 41, and a piston 34 is pressed rightward. Therefore, the pressurized air in an air tank 40 is introduced into the working chamber 27 of a pneumatic actuator 31, and the piston 23 is pressed rightward, and a clutch mechanism is cut off.</p> |
