Body；Brake chamber diaphragm includes rounded bottom, cone-shaped side wall and annular seal lip；The rounded bottom is provided with center
Through-hole is provided with several annular grooves between the rounded bottom and cone-shaped side wall；
U-loop slot is provided on the inside of the annular seal lip, the U-loop trench bottom normal section is semi arch,
The semicircle arc radius is 4-6mm, and the lateral wall and between perpendiculars angle of the U-loop slot normal section are 4-6 °；
The inserts with central through hole is provided at the rounded bottom center, inserts effect is to facilitate positioning and installation.
The semicircle arc radius is 4.5mm, and the lateral wall and between perpendiculars angle of the U-loop slot normal section are 5 °.
3 annular grooves are provided between the rounded bottom and cone-shaped side wall；The height of the annular groove is
0.3-0.7mm, the width of annular groove are 0.5-0.7mm.
The height of the annular groove is 0.5mm, and the width of annular groove is 0.6mm.
The rounded bottom is provided centrally with bottom bulge loop, is provided with inner groovy, the inserts on the inside of the bottom bulge loop
One end is provided with plush copper, and the shape of the plush copper and inner groovy matches, and plush copper is inlayed die casting with inner groovy and connect.
The inserts is metal insert.
Compared with prior art, the beneficial effects of the present invention are:
1 ﹚ of ﹙ is provided with U-loop slot on the inside of the circular ring shape outer side edges of high sealing seal rubber diaphragm, can slow down leakage, more
Sealing performance of the good guarantee diaphragm in brake chamber；
2 ﹚ of ﹙ is provided with metal insert at diaphragm of rubber central through hole, and effect is to facilitate positioning and installation；This rubber system
Dynamic air chamber diaphragm is used in double gas chamber brakes；
3 ﹚ of ﹙ is in previous similar products, the too deep too money of annular groove setting, the frangibility in actually fold use；?
In this product, it is provided with several between rounded bottom and cone-shaped side wall than shallower small annular groove, diaphragm can be made to exist
It is easier to turn down when work, is not easily broken, the service life of product can be increased, by testing fatigue, similar products originally reached
To 1,000,000 times, it now is possible to reach 2,500,000 times；
4 ﹚ of ﹙ and the sealed groove of automobile brake brake component are used cooperatively, and can be widely used in to product seal request
It is relatively high, require product orientation relatively high and relatively high life requirements diaphragm of rubber product applications.
