Title: Auto-clutch device for a vehicle
Inventor: HWANG MAN-YONG
IPC: B60K23/02
Filed: 1992-01-24
Granted: 1994-10-19
Abstract: By using compressed air controlled by electrical control unit and compressed by clutch booster, stick-car drivers need not keep the clutch pedal being pressed on, in low speed. When the speed or engine's rpm goes down under a limit, these data inputted to electrical control unit. As the clutch status is not neutral, the control unit turn off the first solenoid valve (4) and turn on the second solenoid valve (5) to change the status of clutch neutral. This mechanism offers manufal mode (control the clutch by foot) too.
