Claims

[Scope of Claim for Utility Model Registration] A clutch actuator consisting of an air cylinder and an oil cylinder for moving a clutch toward and away from the clutch, an air tank selectively communicating with the air cylinder, and the air cylinder and the above. A first electromagnetic valve selectively communicates with an air tank to operate the clutch actuator in the direction of clutch disengagement, and the air cylinder is intermittently opened to the atmosphere to connect the clutch actuator to the clutch. A second solenoid valve that operates in the direction of In an automatic transmission system for a vehicle having a transmission controller, a push rod is connected at one end to the piston of the oil cylinder and at the other end to a clutch release lever, and whose stopping position gradually changes as the clutch wears. a push rod displacement sensor that detects the stop position and outputs a clutch wear signal; a clutch stroke sensor that detects the displacement amount of the piston of the air cylinder and detects the stroke position of the clutch; and a unit time of the second solenoid valve. a duty circuit that controls the energization time per hit, and an automatic controller that receives the wear signal of the clutch and outputs a control signal to the duty circuit to change the duty ratio of the second solenoid valve as the clutch wears out. An automatic transmission system for a vehicle, characterized by comprising a transmission controller.
