Abstract
The utility model discloses an air valve seat of an automobile vacuum booster, which comprises an air valve seat body and an O-shaped sealing ring. The O-shaped sealing ring is installed at the position of a clamping spring at the front end of the air valve seat body, and the O-shaped sealing is molded in vulcanization mode. The air valve seat well resolves the problem of vacuum assistance failure caused by the fact that the clamping spring of the air valve seat of the automobile vacuum booster is dropped and improves automobile running safety and automobile brake efficiency accordingly.
Description
Technical field
The utility model relates to the auto parts and components field, especially the vacuum booster field.
Background technology
Automobile vacuum booster is a vitals in the brake system of car, and traffic safety is played crucial effects.Along with the continuous development of auto-industry, brake servo unit of all categories is developed, so that obtain bigger braking deceleration through less brake pedal force, to improve mental awareness property and brake efficiency.
But in the braking procedure of present automobile vacuum booster, product vacuum servo can occur and lose efficacy, and its reason is because the volume jump ring of air valve seat comes off.
The utility model content
The technical matters that the utility model will solve is, in the past automobile vacuum booster air valve seat improved, so that solve the problem that the vacuum servo that in braking procedure, occurs lost efficacy.
For solving the problems of the technologies described above, the technical scheme of the utility model is following:
A kind of automobile vacuum booster air valve seat comprises air valve seat and O RunddichtringO, and air valve seat front end jump ring place is equipped with the O RunddichtringO, and the O RunddichtringO is a sulfidization molding, and the choker relief valve front end is embedded with the ring skeleton of integrated vulcanizing moulding.
Compared with prior art, the beneficial effect of the utility model is:
The utility model in Motor Vehicle Braking Procedure, the problem that the vacuum servo that causes of can fine solution automobile vacuum booster air valve seat jump ring coming off lost efficacy.
Description of drawings
Fig. 1 is the integral structure scheme drawing of the utility model.
