Abstract

The invention discloses a clutch power-assisted device which comprises a hydraulic cylinder body and a pneumatic cylinder body; a hydraulic control cavity is formed in the hydraulic cylinder body; a relay piston is arranged in the pneumatic cylinder body and is perpendicular to the hydraulic control cavity; and the top surface of the relay piston is communicated with the hydraulic control cavity. By adopting the clutch power-assisted device, thorough isolation between a pressure control cavity and the hydraulic control cavity in valve bodies is realized, and the problems of air mixing and oil mixing in the valve bodies are solved.

Description

technical field [0001] The invention relates to automobile components, in particular to a clutch booster. Background technique [0002] The clutch assisting device is set in the hydraulic control mechanism and shares a set of compressed air source with the air brake system and other pneumatic equipment. [0003] At present, in the clutch booster device used in the prior art, when the clutch is separated and boosted, the pressure oil of the master cylinder is input into the hydraulic control chamber from the oil inlet, and acts on the piston shaft, so that the piston shaft generates a thrust to the left, and at the same time the hydraulic control The hydraulic pressure of the cavity acts on the relay piston, so that the relay piston moves to the left, the exhaust valve is closed, the valve moves down, the intake valve is opened, the compressed air passes through the intake port and the valve, and the booster piston is pushed to the left. Under the simultaneous action of hydr...
