Linear elasticity curve is suitable for wheel damping and seat damping etc., but air spring is when in use, if instantaneous stamping is too
Greatly, it is easy to the capping of spring be caused to blow or balloon burst.
Utility model content
Air of the larger pressure without damage can be born the technical problem to be solved by the present invention is to provide a kind of
Spring.
The technical solution of the utility model is：
A kind of air spring, including two air bags of arrangement symmetrical above and below and the bumper bracket among two air bags, institute
State air bag include annular cyst wall and concave ring, capping and support ring, it is described capping by be located at cyst wall opening crimping with
Cyst wall fastens；The cyst wall bottom surface is supported ring seal and lives, there are one the middle part of the support ring is set to air bag sunken inside
Concave ring；Limited block there are one being all provided on the inside of the concave ring, limited block is bolted by the connection across bumper bracket, and is being limited
It is lined with sealing ring between position block and concave ring inside bottom wall；The air bag is equipped with aerating mouth.
Further, the aerating mouth of air bag is mutually independent two, is not connected to mutually.
Further, aerating mouth is located at the side of bumper bracket, and by being located at the appendix inside bumper bracket and air bag phase
Even.
Further, crimping cross section is circle, 25% of joint face no more than crimping circular arc of crimping and cyst wall.
Further, the outer rim of bumper bracket is identical as the cyst wall outer diameter size of air bag.
The utility model is beneficial in that：
The utility model uses two independent air bags, is connected with bumper bracket between two air bags, relative to independent
Air bag buffering effect it is more preferable, pressure-bearing is stronger.Capping simultaneously is fastened by being located at the crimping of cyst wall opening with cyst wall, is enhanced
The bonding strength of capping and cyst wall avoids capping under high pressure from being detached from cyst wall.Cyst wall bottom surface is supported ring seal and lives, support ring
Middle part set to air bag sunken inside there are one concave ring, be all provided on the inside of concave ring there are one limited block, the setting of concave ring can block
Firmly bumper bracket avoids bumper bracket from generating larger lateral displacement in instantaneous stamping and air bag, tears air bag, and limited block can
Air bag compression will not be excessive when ensureing that pressure is excessive, and air bag is caused to damage.Therefore the utility model can bear larger pressure
By force.

Specific implementation mode
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1：
A kind of air spring, including two air bags 1 of arrangement symmetrical above and below and the bumper bracket 3 among two air bags 1,
The air bag 1 includes the cyst wall 11 and concave ring 12 of annular, capping 8 and support ring 13, and the capping 8 is by being located at cyst wall 11
The crimping 14 of opening is fastened with cyst wall 11；11 bottom surface of the cyst wall is supported ring 13 and closes, the middle part of the support ring 13
Set to 1 sunken inside of air bag there are one concave ring 12；The inside bottom wall of the concave ring 12 is all provided with there are one limited block 2, the limit
Block 2 is lined between 12 inside bottom wall of the limited block 2 and concave ring close by the connection of connection bolt 5 across bumper bracket 3
Seal ring 4；The air bag 1 is equipped with aerating mouth 7.
Preferably, the aerating mouth 7 of air bag 1 is mutually independent two, is not connected to mutually.
Preferably, aerating mouth 7 is located at the side of bumper bracket 3, and by being located at the appendix 6 inside bumper bracket 3 and air bag 1
It is connected.
Preferably, 14 cross section of crimping is circle, and crimping 14 and the joint face of cyst wall 11 are no more than 14 circular arc of crimping
25%.
Preferably, the outer rim of bumper bracket 3 is identical as the 11 outer diameter size of cyst wall of air bag 1.
The utility model uses two independent air bags 1, is connected with bumper bracket 3 between two air bags 1, relative to list
Only 1 buffering effect of air bag is more preferable, and pressure-bearing is stronger.Crimping 14 and cyst wall 11 of the capping 8 simultaneously by being located at the opening of cyst wall 11
It fastens, enhances the bonding strength of capping 8 and cyst wall 11, capping 8 under high pressure is avoided to be detached from cyst wall 11.11 bottom surface of cyst wall quilt
Support ring 13 closes, and the middle part of support ring 13 sets that there are one concave rings 13 to 1 sunken inside of air bag, and the inside of concave ring 13 is equipped with
