Heavy vehicle clutch automatic control system

A heavy duty vehicle automatic clutch control system of the gas tank (1), the electronic control unit (2), a hydraulic pressure source means (3), a clutch control valve (4), the booster pilot gas cylinder (5), release fork (6), a clutch (7) and displacement sensors (8), wherein the clutch control valve consists of a valve body and two high-speed switching solenoid valve (2) transmits a pulse width modulation signal to the high speed switching means controlled by an electric solenoid valve, clutch disengagement can be controlled, in combination, to maintain operating conditions, the speed of changing the duty cycle in combination with a separate pulse width modulation signal can be controlled clutch (7), the displacement sensor (8) detecting the clutch pressure plate stroke, the clutch can be achieved (7) closed loop control in conjunction with the target position and velocity. The original system of the vehicle air assist pilot clutch mechanism changes little, simple structure, convenient arrangement, adapted easily manufactured, reliable control can meet the needs of a heavy vehicle air booster pilot clutch automatically controlled.
