Description
Technical field
The utility model is a kind of rail traffic air chamber diaphragm, in particular to high sealing brake chamber diaphragm, belongs to system
The component or part technical field of dynamic device.
Background technique
Brake chamber diaphragm, that is, rubber diaphragm of braking air chamber is the product for being sandwiched between canvas, is widely used in track friendship
It is the core part in various heavy track vehicular traffic brake components in logical brake and drive system for vehicle with tow, is related to vehicle driving peace
Entirely, vehicle generates hyperbar and pushes rubber diaphragm for vapor chamber displacement, increase gas chamber pressure, and then push push rod forward in braking,
Motive force is finally passed to the brake patch taken turns in firm, opens brake block, wheel is held tightly, plays braking effect, reach brake
Purpose.So rubber diaphragm for vapor chamber is essential key part in rail traffic vehicles.
After existing rubber diaphragm of braking air chamber is used for a long time, due to edge abrasion, sealing performance is reduced, cause to brake
The working efficiency of gas chamber is greatly reduced；Utility model title are as follows: a kind of novel automobile brake air chamber rubber diaphragm, Authorization Notice No.
Are as follows: CN201090408Y is respectively arranged with the seal line of annular protrusion on upper and lower two inclined-plane of seal lip, to braking gas
Room plays sealing function, but easy to wear and lose its effect.
During the work time, due to the effect of high pressure, strength, diaphragm of rubber body turns over existing rubber diaphragm of braking air chamber
Turn, product is be easy to cause to tear；Utility model title are as follows: rubber diaphragm of automobile brake chamber, Authorization Notice No. are as follows:
CN2874063Y is provided with arc groove in diaphragm of rubber bottom, but because the depth of slot is too big, reaches 1.5-2mm, produces to diaphragm of rubber
The self-strength of product produces adverse effect, cannot still completely eliminate product tearing phenomenon.
Utility model content
The purpose of this utility model be for it is above-mentioned in the prior art, the low defect of sealing performance provides a kind of highly dense
Brake chamber diaphragm is sealed, can achieve the high purpose of sealing performance.
To achieve the goals above the technical scheme adopted by the utility model is that: high sealing brake chamber diaphragm, it is simple below
Claim brake chamber diaphragm, brake chamber diaphragm is integrally rounded, and the diameter of air chamber diaphragm is 96.7mm, and the height of air chamber diaphragm is
20.5mm；The air chamber diaphragm is circular basin-like body in intermediate recessed, periphery；Brake chamber diaphragm includes rounded bottom, cone
Bodily form side wall and annular seal lip；The rounded bottom is provided with central through hole, the rounded bottom and cone-shaped side wall
Between be provided with several annular grooves；
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 height of the annular groove is 0.3-0.7mm, and the width of annular groove is 0.5-0.7mm.
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
0.5mm, the width of annular groove are 0.6mm.
Compared with prior art, the utility model has the beneficial effects that
1 ﹚ of ﹙ is provided with U-loop slot on the inside of the circular ring shape outer side edges of high sealing brake chamber diaphragm, can slow down leakage, more
Sealing performance of the good guarantee diaphragm in brake chamber；
For 2 ﹚ of ﹙ in previous similar products, annular groove setting is too deep too wide, 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；
The sealed groove of 3 ﹚ of ﹙ and automotive brake component is used cooperatively, and can be widely used in and be compared to product seal request
The high and relatively high braking diaphragm of rubber product applications of life requirements.
