Abstract
The utility model relates to an automobile brake booster. The automobile brake booster mainly comprises a shell of the automobile brake booster and a piston, wherein the piston is arranged in the shell; the shell is respectively provided with a spring braking chamber driving cavity interface, a spring braking chamber parking cavity interface and a gas storage barrel interface; the piston inside the shell is connected with a valve; a gas cavity is arranged between the valve and the shell, and the gas cavity is communicated with the spring braking chamber driving cavity interface; the valve is provided with a small hole, and the small hole is communicated with the spring braking chamber parking cavity interface and the gas storage barrel interface. The automobile brake booster disclosed by the utility model is suitable for a large-size automobile.
Description
Technical field
The utility model relates to a kind of car brake, especially relates to a kind of automobile brake booster.
Background technology
Owing to the needs of transportation development, big automobile is increasing at present, and superimposed trailer is more and more longer; In brake process, the phenomenon that back car pushes away front truck is very general, adopts synchronous RE valve; Though can accelerate the brake of trailing wheel, remove the wheel that brake is considerably slower than front part of vehicle, cause the trailing wheel car that stagnates; Recovery is gone slowly, brake shoe serious wear, brake drum heating.Traditional RE valve not too has been applicable to the lengthening automobile, and the problem that solves the trailing wheel braking with the quantity that increases relay valve neither best choice, and traditional brake activation valve can't satisfy the needs of automobile brake because its braking force is not enough.
Summary of the invention
The purpose of the utility model is to provide a kind of reasonable in design to the existing shortcoming of above-mentioned car brake, increases outstanding effect automobile brake booster.
In order to achieve the above object, the utility model mainly adopts following technical scheme to realize.The utility model mainly is made up of the housing of booster and the piston of being located in the housing; On housing, be respectively equipped with and connect driving chamber, brake application by spring chamber interface, connect parking chamber, brake application by spring chamber interface and connect the gas storage barrel interface, the piston in housing connects valve; Be provided with air cavity between valve and the housing; Air cavity is communicated with driving chamber, brake application by spring chamber interface, and valve is provided with aperture, and aperture is communicated with brake application by spring chamber parking chamber interface and gas storage barrel interface.
The utility model is applicable to full-sized car.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model integral structure cut-away view.
Fig. 2 is the utility model integral structure outside drawing.
The specific embodiment
As depicted in figs. 1 and 2, the utility model mainly is made up of the housing 1 of booster and 2 in the piston of being located in the housing 1, on housing 1, is respectively equipped with to connect driving chamber, brake application by spring chamber interface 7; Connect parking chamber, brake application by spring chamber interface 3 and connect gas storage barrel interface 8; Piston 2 in housing 1 connects valve 4, is provided with air cavity 6 between valve 4 and the housing 1, and air cavity 6 is communicated with driving chamber, brake application by spring chamber interface 7; Valve 4 is provided with aperture 5, and aperture 5 is communicated with parking chamber, brake application by spring chamber interface 3 and gas storage barrel interface 8.
Embodiment
When 1, normally driving a vehicle, gas storage barrel interface 8 is connected with parking chamber, brake application by spring chamber interface 3, the chamber of brake application by spring chamber driving at this moment interface 7 no gas, and braking function does not have.
2, when when brake, air cavity 6 is communicated with driving chamber, brake application by spring chambers interface 7, when reaching certain air pressure; S1 * P1＞S2 * P2 promotes piston 2 gas storage barrel interface 8 and parking chamber, brake application by spring chamber interface 3 is broken off, parking chamber, brake application by spring chamber interface 3 straight-through atmosphere; Parking chamber, brake application by spring chamber air pressure is descended; The retarding spring release of pressure is split into stress, reaches the purpose that power increases.
The utility model is applicable to full-sized car.
