Abstract
The utility model discloses a clutch servo device, comprising a servo-cylinder assembly and a servo device casing connected to the cylinder body. The servo device casing is provided with an operating cylinder assembly and a mushroom air admission valve connected to an air inlet connector; a piston and a piston pushing rod are arranged in the servo-cylinder casing of the servo-cylinder assembly; one end of the piston pushing rod contacts with the piston arranged in the operating cylinder assembly; the other end is fixed on the servo-cylinder piston via the pushing rod arranged in the servo-cylinder casing; bolts and the servo-cylinder casing adopt riveted structure. A stress surface of a spherical sphere which is at one end of the piston pushing rod and contacts to the piston arranged in the operating cylinder assembly, is changed to a plane groove and adopts plane stress. A pushing rod is arranged in the operating cylinder whose port is provided with a thrusting shim and a circlip for hole, a dirt guard is arranged outside the operating cylinder to protect the operating cylinder, and a breather pipe and an air evacuation valve are connected to the dirt guard. A flange is arranged on the frame of the mushroom air admission valve, and prevents the rubber from shedding. The utility model is adapted for a freight car, a passenger car, and a machine shop car.
Description
Technical field
The utility model relates to a kind of automobile component, especially relates to a kind of automobile clutch booster.
Background technique
The clutch booster that uses on the automobile is to develop into clutch booster on the basis that clutch hydraulic pressure is handled, because clutch working cylinder only plays gearing, can not alleviate driver's pedaling force, especially the automobile of clutch diameter more than 325mm, do not have booster, driver's labor intensity is too big.In the clutch booster that uses, mainly exist following shortcoming at present: (1), the method for screw on the servo-cylinder housing are to adopt welding fixing (brazing or argon arc welding).The shortcoming of this structure is to produce poor stability in batches, easily produces the sealing-off phenomenon.(2), the servo-cylinder piston push rod is that sphere contacts with operating cylinder piston surface of contact, makes servo-cylinder piston push rod, operating cylinder piston eccentric wear easily.(3), not thrust washer and circlip for hole, in entrucking and process on probation, operating cylinder drops out easily at the operating cylinder port.(4), dust-proof cover adopts closed or add the structure of aperture, makes hydraulic control partly advance air, water and dust easily.(5), bacterium shape suction valve comes unstuck easily.
Summary of the invention
The purpose of this utility model is at the existing shortcoming of above-mentioned automobile clutch booster, and a kind of design science is provided, and carries out improved clutch booster at its shortcoming.
For achieving the above object, the utility model has mainly adopted following technological scheme to realize.The utility model reaches the booster housing that links to each other with its cylinder body by the servo-cylinder assembly to be formed, and is provided with operating cylinder assembly and the bacterium shape suction valve that links to each other with air input joint in the booster housing.Be provided with piston and piston push rod in the servo-cylinder housing of servo-cylinder assembly, one end of the piston push rod piston interior with being located at the operating cylinder assembly contacts, the other end is fixed on the servo-cylinder piston by the screw bolt seat of being located in the servo-cylinder assembly, and bolt and servo-cylinder housing adopt riveted structure.One end of described piston push rod changes plane groove into the contacted spherical sphere stress surface of being located in the operating cylinder assembly of piston, adopts the plane stressed.Also be provided with push rod in the operating cylinder, the port of operating cylinder is provided with thrust washer and circlip for hole, and the outside is provided with the dust-proof cover protection, and dust-proof cover is provided with a breathing pipe and links to each other with outlet valve.The skeleton of described bacterium shape suction valve is provided with flange, comes off to prevent rubber.
The utility model compared with prior art has following obvious advantage and good effect.(1), adopt in the servo-cylinder housing riveted structure to fix bolt, in order to reach the purpose of set screw, make the product lot quantity good stability, the sealing-off phenomenon can not appear, can guarantee the normal use of product effectively.(2), an end of piston push rod changes plane groove into the contacted spherical sphere stress surface of being located in the operating cylinder assembly of piston, adopts the plane stressed, eliminated servo-cylinder piston push rod and operating cylinder piston eccentric wear and crossed positioning phenomenon.(3), the operating cylinder port is provided with thrust washer and circlip for hole structure, prevents that piston from dropping out.(4), adopt breathing pipe and the outlet valve structure that communicates on the dust-proof cover, avoided the shortcoming of conventional construction.(5), the skeleton of bacterium shape suction valve is provided with flange, prevents that rubber from coming off.
The utility model is applicable to lorry, passenger vehicle and engineering truck.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
