Problems solved by technology

[0004] During the development of this product, it was found that the traditional clutch pedal control hydraulic power-assisted clutch has a problem of heavy pedal force. After analysis: due to the space limitation of the cab layout, it is impossible to realize the hydraulic pressure and adjust the lever ratio of the clutch pedal by increasing the cylinder diameter of the hydraulic clutch master cylinder. To reduce the clutch pedal force value to reduce driving fatigue

Abstract

The invention relates to a clutch master pump and a clutch assembly equipped with the clutch master pump. A pump body is internally provided with an air cylinder (22), an ejection rod shaft (6) and a return spring (7); an air inflow seat (2) is connected with the pump body; the clutch master pump is characterized in that the pump body is internally provided with an oil cylinder (12); a power-assistance piston (5) is mounted at the front end of the ejection rod shaft (6); the power-assistance piston (5) and the front end of the pump body form the air cylinder (22); the rear end of the ejection rod shaft (6) and the rear end of the pump body form the oil cylinder (12); and the air cylinder (22) is linked with the oil cylinder (12) through reciprocating motion of the ejection rod shaft (6). The clutch master pump converts pneumatic power-assistance clutch to hydraulic power-assistance clutch through manipulation of a clutch pedal, so that the traditional hydraulic power-assistance clutch mode through the manipulation of the clutch pedal is changed, the manipulation comfortability is improved, and the working strength of a driver is reduced.

Description

technical field [0001] The invention relates to the field of motor vehicle clutches, in particular to a clutch master cylinder and an assembly equipped with the clutch master cylinder. Background technique [0002] The clutch master cylinder is the part connected to the clutch pedal and connected to the clutch booster through the oil pipe. The function is to collect the pedal travel information and realize the separation of the clutch through the action of the booster. When the clutch is disengaged, the master cylinder is used to assist the clutch disengagement, temporarily cut off the power, and realize the effect of easy gear shifting. Therefore, the performance of the clutch master cylinder directly affects the separation of the clutch and the operation of the motor vehicle. [0003] The Chinese utility model patent No. 201120395739.9 discloses a clutch master cylinder, which includes a valve body, a main piston and a push rod; the main piston is installed in the valve ...
