Abstract
The utility model discloses a kind of brake epitheliums, it includes epithelium body（1）With epithelium bottom（2）, at epithelium bottom（2）Outer bottom be equipped with circular boss concentric with it（3）, in circular boss（3）Distal end faces on be evenly equipped with protrusion（4）.The utility model can be effectively prevented from epithelium bottom and be worn, increase brake epithelium service life, can solve epithelium bottom in the prior art integrally thicken and inhibit brake epithelium elastic recovery sex chromosome mosaicism, accelerate brake epithelium reset speed.
Description
Technical field
The utility model belongs to brake chamber parts technical field, is specifically related to a kind of brake epithelium.
Background technology
Brake epithelium also known as rubber detent epithelium, is to act the rubber folder for transmitting pressure suitable for automobile brake room
Fabric diaphragm, operating pressure are 0.5-0.8MPa, and operating temperature is-40 -+70 DEG C.The brake rubber block used in the prior art
Film, the outer bottom at epithelium bottom are smooth shape, in the course of work under the effect of top pressure repeatedly of push rod, the outer bottom face at epithelium bottom
It easily wears, eventually leads to the rupture of epithelium bottom, shorten the service life of brake epithelium；For this problem, the prior art solves
Method be increase the thickness at entire epithelium bottom, although this method can effectively extend brake epithelium service life, also press down
The memory of brake epithelium is made.
Invention content
The technical problems to be solved in the utility model is to provide a kind of can prolong the service life and memory is good
Brake epithelium, can be with overcome the deficiencies in the prior art.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of brake epithelium, it include epithelium body and
Epithelium bottom is equipped with circular boss concentric with it on the outer bottom at epithelium bottom, in the distal end faces of circular boss
It is furnished with protrusion.
Above-mentioned brake epithelium is that the thickness of the annular shape boss is 1mm.
Above-mentioned brake epithelium is that the shape of the protrusion is cylindrical or hemispherical.
Compared with the prior art, circular boss concentric with it is arranged in the utility model on the outer bottom at epithelium bottom,
The uniformly distributed protrusion in the distal end faces of circular boss, in use, protrusion is in direct contact instead of traditional epithelium bottom with push rod, i.e.,
Epithelium bottom can be effectively prevented to be worn, to increase the service life of brake epithelium；Circular boss and protrusion are arranged in skin
The outer bottom central region at film bottom, can solve epithelium bottom in the prior art integrally thicken and inhibit brake epithelium elastic recovery
Sex chromosome mosaicism accelerates the reset speed of brake epithelium.In addition, the utility model also has simple in structure, ingenious in design and is produced into
This cheap advantage.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the front view of the utility model.
Fig. 3 is the upward view of the utility model.
Fig. 4 is the vertical view of the utility model.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only the section Example of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The all other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in attached drawing 1, attached drawing 2, attached drawing 3 and attached drawing 4, a kind of brake epithelium, it includes epithelium body 1 and epithelium bottom 2,
It is equipped with circular boss 3 concentric with it on the outer bottom at epithelium bottom 2, is evenly equipped in the distal end faces of circular boss 3
Protrusion 4.The thickness of the annular shape boss 3 is 1mm；Raised 4 shape is cylindrical or hemispherical.
Specifically, the outer diameter of the circular boss 3 is Φ 55mm, and internal diameter is Φ 15mm.The epithelium body 1, epithelium bottom
2, circular boss 3 and protrusion 4 are an integral structure.
The preferred embodiment in the utility model disclosed above is only intended to help to illustrate the utility model.Preferred embodiment is simultaneously
There is no the details that detailed descriptionthe is all, does not limit the specific implementation mode that the utility model is only described yet.Obviously, according to this theory
The content of bright book can make many modifications and variations.Embodiment is chosen and specifically described to this specification, be in order to preferably explain
The principles of the present invention and practical application, to enable skilled artisan to be best understood by and utilize this practicality
It is novel.
