Description
Technical field
The invention belongs to vehicle braking product technical fields, are related to a kind of braking epithelium, and especially a kind of brake chamber is used
Epithelium and production method.
Background technique
With the development of science and technology high-speed rail (track) traffic has become more more and more universal trip mode, with big both at home and abroad
The be open to traffic operation and faster speed of high-speed rail (track) traffic between amount city and in city, longer service life,
To braking diaphragm, more stringent requirements are proposed.
It is universal because of rail traffic, to meet the higher speed of current and future high-speed rail (track) traffic and safer
Performance, it is necessary to existing diaphragm structure preferably be designed, to meet braking requirement.
Summary of the invention
The purpose of the present invention is in view of the above-mentioned problems existing in the prior art, propose a kind of brake chamber epithelium and system
Make method, it is an object of the invention to overcome drawbacks described above of the existing technology, strengthens the sealing braking effect of braking epithelium
Fruit extends service life, meets the brake request under low temperature.
Object of the invention can be realized by the following technical scheme: a kind of brake chamber epithelium, including rubber material
Epithelium main body, epithelium main body includes the lip for connecting with checking cylinder, the epithelium main body for contacting with stressed member
Connection wall between bottom, connection lip and bottom, the lip is interior to be arranged lip skeleton, and the bottom outside connects bottom mould
Plate, the epithelium main body is interior to be arranged nylon cord fabrics layer, and the connection wall is thinner than lip and bottom.Lip skeleton is the full inclusion of rubber
Structure provides biggish pressure-resistant deformable supports for lip, plays reinforcement sealing function.The wall thickness of connection wall is relatively thin to can be improved product
To the susceptibility of power output, polyamide skeleton can provide stronger strength support effect, meet the effect of the safety arrestment of power output.
In above-mentioned brake chamber epithelium, the bottom of the bottom template edge insertion epithelium main body.
In above-mentioned brake chamber epithelium, the bottom of the epithelium main body has the bottom template insertion outwardly protruded
Slot.
Circle for contacting with stressed member is set in above-mentioned brake chamber epithelium, in the middle part of the bottom template
Groove.It is designed for circular groove centre, it is therefore an objective to have the wear-resisting effect that preferably supports with drive apparatus, increase service life and peace
Quan Xing.
In above-mentioned brake chamber epithelium, the nylon cord fabrics layer for connecting wall part is in the unilateral side of sizing material.
In above-mentioned brake chamber epithelium, lip skeleton material is Q235D/45# steel.
In above-mentioned brake chamber epithelium, cord is NTB90 nylon cord fabrics.
A kind of production method of brake chamber epithelium:
Step 1: the sizing material in epithelium, which is divided into two parts and skeleton up and down, carries out vulcanization sizing；
Second step, nylon cord fabrics and the bonding sizing of epithelium lower half portion sizing material；
Third step epithelium top half sizing material and has bonded stereotyped nylon cord fabrics and epithelium lower half portion sizing material and lip
Mouth skeleton carries out bonding vulcanization.
Compared with prior art, this brake chamber is had the advantage that with epithelium and production method
Lip skeleton primarily serves installation supporting role, and making product is not in that deformation is larger, and lip deformation is caused to lose sealing
Effect loses braking function；Rubber and nylon cord fabrics primarily serve the effect of gas storage and the transmission of power, and bottom template is main
Wear-resisting and support effect is played, is prolonged the service life.
Detailed description of the invention
Fig. 1 is the cross-sectional view of embodiment one.
In figure, lip 1, bottom 2, connection wall 3, lip skeleton 4, bottom template 5, nylon cord fabrics layer 6, template embedded groove 7,
Circular groove 8.
Specific embodiment
The following is specific embodiments of the present invention, and technical scheme of the present invention will be further described in conjunction with attached drawing,
However, the present invention is not limited to these examples.
Embodiment one
As shown in Figure 1, a kind of brake chamber epithelium, the epithelium main body including rubber material, epithelium main body include for system
The lip 1 that dynamic cylinder connects, the bottom 2 of the epithelium main body for being contacted with stressed member (such as piston), connection lip and bottom
Between connection wall 3, lip skeleton 4 is set in the lip, and the bottom outside connects bottom template 5, the epithelium main body
Interior setting nylon cord fabrics layer 6, the connection wall is thinner than lip and bottom.Lip skeleton is the full pack arrangement of rubber, is provided for lip
Biggish pressure resistance deformable supports, play reinforcement sealing function.The relatively thin product that can be improved of the wall thickness of connection wall is to the quick of power output
Sensitivity, polyamide skeleton can provide stronger strength support effect, meet the effect of the safety arrestment of power output.
It is 60mm that the bottom template, which is outer diameter, and with a thickness of the circular metal block of 5.35mm, the bottom template edge is embedding
Enter the bottom of epithelium main body.The bottom of the epithelium main body has the bottom template embedded groove 7 outwardly protruded, i.e., the described bottom mould
Circular groove 8 for contacting with stressed member is set in the middle part of plate.It is designed for circular groove centre, it is therefore an objective to have with drive apparatus
Wear-resisting effect is preferably supported, service life and safety are increased.
The nylon cord fabrics layer of connection wall part is in the unilateral side of sizing material, wall thickness 1.5mm.Lip skeleton material is Q235D/
45# steel, lip is with a thickness of 8.3mm.Lip skeleton thickness design is 4mm, and width 6.7mm, lip is with a thickness of 8.3mm, cord
