Abstract
The utility model discloses a spring brake chamber with a long service life, wherein the spring brake chamber with the long service life is good in guide effect, and long in service life. The spring brake chamber with the long service life comprises a middle shell body, a guide hole is formed in the middle of the middle shell body, a shaft sleeve is arranged in the middle of the guide hole, a recessed groove is formed in the inner periphery of the shaft sleeve, and graphite is arranged inside the groove. The spring brake chamber with the long service life is suitable for automobile brake.
Description
Technical field
The utility model relates to a kind of automobile brake system, relates in particular to the spring brake chamber in a kind of automobile brake system.
Background technique
Spring brake chamber is a vitals for brake system of car such as heavy-load automobile, extraordinary commercial vehicles, and the quality of its performance is directly connected to the Security of service brake.Spring brake chamber comprises middle shell, be provided with pilot hole in the middle of the middle shell, pilot hole not only need have guide function, also need have sealing function, and O-ring seals only is housed on the common pilot hole, in push rod and the frequent contact process of pilot hole, seal ring produces wearing and tearing, distortion or distortion easily, thereby affects seal ring working life, the middle shell material is aluminum alloy simultaneously, and the material of push rod is steel, thereby produces inordinate wear easily, thereby impact is led, sealability.
The model utility content
The technical problems to be solved in the utility model provides that a kind of guide effect is good, the resistant spring brake chamber of long service life.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises middle shell, is provided with pilot hole in the middle of the described middle shell, is provided with axle sleeve in the middle of the described pilot hole, week is provided with groove in the described axle sleeve, is provided with graphite in the described groove.
The utility model compared with prior art has following obvious advantage and beneficial effect:
1, guide effect is good.Because the utility model is set up axle sleeve in the middle of pilot hole, improve the wear resistance at guiding position, thereby improve guide effect.
2, long service life.Because thereby the utility model Zhou Zengshe in the axle sleeve in the middle of the pilot hole, because graphite has good wear resistance effectively increases the service life with the groove of graphite.
