Title: Clutch operating device
Inventor: TAKAIWA KIYOYUKI
IPC: F16D25/08
Filed: 1987-10-21
Abstract: PURPOSE:To smooth the running of a vehicle at a low speed during semi-clutch operation by opening a large flow capacity solenoid valve in a short time in synchronization with the initiation of opening of a small flow capacity valve when a piston is operated at a predetermined stroke position at which a clutch shifts into a turn-off condition from a turn-in condition or vice versa. CONSTITUTION:During a vehicle running at a low speed in a half-clutch condition, a large flow capacity solenoid valve 18 or 19 is opened in a short time in synchronization with the initiation of opening of a small flow capacity solenoid valve 20 or 21. Accordingly, even though a piston 6 in an actuator 1 is stopped once at a predetermined stroke position, the piston 6 can be reversed at once after the solenoid valve 20 or 21 is opened. That is, even though a larger load is effected when the piston 16 comes once to a stop at a predetermined stroke position, the large flow capacity solenoid valve 18 or 19 abruptly feeds and discharges compressed air. Accordingly, an amount of compressed air corresponding to a hysteresis can be fed and discharged in a short time so that the engagement and disengagement of the clutch can be started rapidly, thereby it is possible to improve the responsiveness.
