Description
Technical field
The utility model relates to automobile brake master cylinder technical field, is specifically related to a kind of automobile brake master cylinder standing screw stop collar.
Background technique
Automobile brake master cylinder is hydraulic braking master cylinder for automobile, is also brake master cylinder, is the power source of automobile running braking.Braking force is applied to pedaling force on brake petal and the vacuum servo of engine intake manifold from driver, the Main Function of the master cylinder of automobile is to change braking oil pressure into by being applied to mechanical force on brake petal and the power of vacuum booster, and the brake fluid with certain pressure is delivered to the brake cylinder of each wheel through braking line, then change wheel braking force into by wheel drag.
Current automobile brake master cylinder fixing device is screw rod, screw rod is threaded connection braking overall pump and vehicle body is fixed, in carrying the brake fluid of certain pressure, the reaction force that braking overall pump brings while being subject to brake fluid braking impacts, frequently easily cause screw rod wearing and tearing, loosening after repeatedly, even affect braking effect.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of reasonable in design, not easy to wear, loosening with the rear screw rod of screw rod socket, connects reliable automobile brake master cylinder standing screw stop collar.
For achieving the above object, the utility model provides following technological scheme: a kind of automobile brake master cylinder standing screw stop collar, comprise stop collar body, in described stop collar body outer wall, be integrally formed with several elastic bumps, and stop collar body two ends are equipped with the screw hole of " T " font, in described screw hole, be equipped with lock screw, and lock screw afterbody arranges lower than screw hole opening, one end outer wall of described stop collar body is obliquely installed towards center line, angle of inclination is 15-45 °, the center bore inner wall face of described stop collar body is provided with internal thread, described lock screw comprises screw rod and nut, screw rod and nut are wholely set, and nut exterior edge face is fixedly installed one deck rubber layer, described rubber layer exterior edge face is concordant with stop collar body outer wall.
By adopting technique scheme, stop collar cover is received after existing screw rod, can play shock absorbing effect at the attachment hole internal face of screw rod by elastic bumps, improve wear-resisting and anti-loosing effect, can effectively alleviate the impact of the reaction force impact bringing when braking overall pump is subject to brake fluid braking, make fixing more reliable.
The utility model is further set to: several elastic bumps evenly arrange along stop collar body outer wall, and elastic bumps longitudinal section is rectangular, and elastic bumps length direction is provided with rounding.By this setting, elastic bumps structure arranges rationally, reliable operation.
The utility model is also further set to: described stop collar body is formed by the manufacture of urethane rubber material, and described rubber layer is urethane rubber layer.By this setting, stop collar body and rubber layer wear resistance are good, and bumper and absorbing shock is good.
The utility model is also further set to: described lock screw is stainless steel screw.By this setting, lock screw is difficult for getting rusty, and installs and removes simple to operately, connects reliable.
The utility model has the advantages that: the utility model structure arranges rationally, stop collar cover is received after existing screw rod, can play shock absorbing effect at the attachment hole internal face of screw rod by elastic bumps, improve wear-resisting and anti-loosing effect, can effectively alleviate the impact of the reaction force impact bringing when braking overall pump is subject to brake fluid braking, make fixing more reliable.
Below in conjunction with Figure of description and specific embodiment, the utility model is described in further detail.
Brief description of the drawings
