Abstract

The invention discloses a hydraulic operating mechanism, an ECU, a clutch system and a car. The hydraulic operating mechanism comprises a clutch separation assistant cylinder, a control valve and a switch device. The control valve is provided with an oil inlet, an oil outlet and an oil discharging hole, the oil inlet communicates with an engine oil pump, and the oil outlet communicates with the clutch separation assistant cylinder. The switch device is used for controlling the oil outlet and the oil inlet of the control valve to communicate through the ECU so that the clutch separation assistant cylinder can be filled with oil, and controlling the oil outlet and the oil discharging hole to communicate so that oil can be discharged from the clutch separation assistant cylinder. The hydraulic operating mechanism controls a clutch to be disengaged and engaged through the switch device in cooperation with the control valve. In addition, during gear shifting each time, a driver can control disengagement of the clutch by operating the switch device, foot action is avoided, the gear shifting operation is convenient, and the labor intensity of the driver is relieved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a hydraulic control mechanism, an ECU, a clutch system and an automobile. Background technique [0002] In existing cars with manual transmission, refer to figure 1 , The hydraulic control mechanism includes: a clutch pedal 1, a master cylinder 2 connected to the pedal 1 through a push rod, and a clutch separation slave cylinder 3 connected to the master cylinder 2 through a hydraulic pipe 4. When shifting gears, first, the driver has to step on the clutch pedal 1, and the clutch pedal 1 drives the push rod of the master cylinder 2 to move, so that the hydraulic oil in the master cylinder 2 flows to the clutch release slave cylinder 3 through the hydraulic pipe 4 to realize clutch release. Then, push the shift lever to switch to the required gear; finally, slowly release the clutch pedal 1, so that the hydraulic oil in the clutch separation auxiliary cylinder 3 flows to the ...
