Background technology
Vacuum booster is the brake power assist unit in brake system of car, is used for assisting driver to be braked, is the critical component in brake system of car.
Suck air when the operation principle of vacuum booster is to utilize electromotor to work, cause the side vacuum of booster, produce pressure differential relative to the pressure of opposite side normal air, utilize pressure differential to produce brake force, it is achieved thereby that the purpose of braking.
When electromotor sucks air, due to extraneous unstability, when sucking air, there is the possibility entering impurity, once impurity enters into inside booster, or block air inlet, all vacuum booster can be produced into and have a strong impact on, power-assisted even can be made to lose efficacy, brake failure, the safety of driver is produced serious threat, therefore, before air inlet, air is carried out dustproof filter and be very important.
The assembling process of a traditional vacuum booster dust preventing component wherein step is to be enclosed within valve body by dirt-proof boot, during assembling, dirt-proof boot need to be packed into by the fork handle that adjustment is pitched, radius due to fork handle is more than the radius of dirt-proof boot rear end face, during assembling, the rear end face large area expansion of dirt-proof boot, this operation easily part is produced damage and assembling yields is low, causes the problems such as rework operation.Meanwhile, the dustproof filter of traditional booster air is only carried out once, may there is the halfway situation of filtration.
Summary of the invention
This utility model provides a kind of vacuum booster dust preventing component, with solve to cause because part expansion is excessive during assembling damage parts and assembling difficulty and booster during dustproof filter only to air filtration once, there is the halfway problem of filtration.
This utility model adopts the technical scheme that: dust-proof filter element is socketed on adjustment fork, and with valve seat interference fit, filter element left side abuts against on valve rod spring abutment, dust-proof filter element is integrally located at the inboard of valve body, dirt-proof boot is enclosed within the outside of valve body, front end groove is stuck on back casing, the rear end face of dirt-proof boot is stuck on the fork arm adjusting fork, the radius of the fork handle adjusting fork is less than the radius of valve body, radius more than the rear end face of dirt-proof boot, adjust the fork arm radius radius more than rear end face of fork, foam filter elements coordinates for interference fit with the annulus of the air inlet of dirt-proof boot, the width of foam is more than the width of air inlet.
The material of described dust-proof filter element is felt.
The rear end face of described dirt-proof boot uses split-type structure.
The material of described dirt-proof boot is elastomer.
The material of described dirt-proof boot is rubber.
The material of described foam filter elements is elastic foam.
The described material adjusting fork is metalwork.
The utility model has the advantages that novel structure, assembling is good, the splitted structure of the rear end face of dirt-proof boot substantially increases the yields of Product Assembly, decreases the incidence rate damaged by fork handle radial force during assembling because of dirt-proof boot, and this utility model adds air inlet on dirt-proof boot, on be covered with foam filter elements, when crossing air filtering, air first passes through foam filter elements, then by dust-proof filter element, air has been carried out secondary filter, and filter effect is better than traditional booster.
