<p>PURPOSE:To give smooth connection to the clutch mechanism of an automobile by connecting a motor, which is controlled by an electronic controller, to a master cylinder, which supplies the pressure oil to a hydraulic, air controlling valve that controls a pneumatic actuator. CONSTITUTION:A crank shaft of an internal combustion engine 51 is connected to or disconnected from an input shaft of a gear-type speed-change-gear 53 via a clutch mechanism 52, and the rotation of an output shaft 55 is transferred to the wheels. A shaft 16 supports a clutch lever 17 to the clutch mechanism. A motor 3, which is controlled by an electronic controller, is connected to a master cylinder 11, which supplies the pressure oil to a hydraulic, air controlling valve 41 that controls a pneumatic actuator 31 driving a clutch lever 17. Accordingly, a hydraulic actuator 21 that is connected to the clutch lever 17 is operated directly by the master cylinder 11, while the pneumatic actuator 31 is operated indirectly by the master cylinder 11 via the hydraulic, air controlling valve 41. The motor 3, which gives the reciprocal motion to the master cylinder 11, is controlled by an encoder 2, according to the signals from the electronic controller.</p> |
