Title:
CLUTCH CONTROLLER FOR COMPOSITE CLUTCH TYPE MULTI-STAGE CHANGE GEAR
Document Type and Number:
Japanese Patent JPS5837358
Kind Code:
A
Abstract:
PURPOSE:To smoothly connect clutches by providing a pressure-regulating solenoid valve intermittently operating for controlling a fluid pressure to be given to a solenoid valve for switching fluid type clutch actuators, in addition to the switching solenoid valve. CONSTITUTION:When accelerator pedal is stepped on for starting, the first control solenoid valve 35 for controlling the connection and disconnection of a clutch 5 excited and ports 35c and 35d are led to each other. Since the excitation of a pressure-regulating solenoid valve 37 is interrupted at the same time, a line 34d is connected with a pathway 38 through the pressure-regulating solenoid valve 37 and the first control solenoid valve 35, and the first clutch actuator 8 is moved in the connecting direction. In the midway of the connecting stroke of the first clutch 5, an exciting current is intermittently given for a short period of time to the pressure-regulating solenoid valve 37, whereby pressure to be applied to the first clutch actuator 8 is gradually and stepwise raised.
