Abstract

The invention discloses a clutch booster high in sealing performance. The clutch booster is provided with a pneumatic cylinder and a hydraulic cylinder, wherein the pneumatic cylinder and the hydraulic cylinder are connected along the same axis, a piston is arranged in the pneumatic cylinder, a push rod connected with the piston is arranged on a front cover plate of the pneumatic cylinder, a first ventilation fluted tube and a second ventilation fluted tube are arranged on the front cover plate, a first movable cover plate is arranged at the position of a port of the first ventilation fluted tube through a spring part, a protruding part is arranged on the inner wall of the port of the first ventilation fluted tube to prevent the first movable cover plate from moving inwards, a second movable cover plate is arranged at the position of the port of the second ventilation fluted tube through a spring part, a protruding part is arranged at the position of the port of the second ventilation fluted tube to prevent the second movable cover plate from moving outwards, the second ventilation fluted tube is connected with a rubber hose, a fixed end is arranged at the air inlet end of the rubber hose, and an air filtering device is arranged at the fixed end. According to the clutch booster high in sealing performance, the overall dustproof effect is improved, the sealing performance of the piston is improved, the service life of the piston is prolonged, and maintenance is convenient.

Description

technical field [0001] The invention mainly relates to a clutch control mechanism for automobile transmission, in particular to a clutch booster with good sealing. Background technique [0002] At present, in the clutch control system of heavy-duty vehicles, buses and construction machinery, due to the heavy force to operate the clutch pedal, the power cannot be cut off in a timely and easy manner, and the gear can be easily shifted. Generally, a clutch booster is installed between the clutch and the clutch master cylinder. The vehicle's compressed air supply powers the clutch. [0003] However, the piston head used in the cylinder of the booster on the market, with the prolongation of the working time, causes the wear of the sealing ring, and the sealing gap cannot be compensated, so that the sealing effect is reduced, causing air leakage, and making the clutch booster invalid. Contents of the invention [0004] The object of the present invention is to provide a clutch ...
