Description
Technical field
The present invention relates to automobile tire technical field more particularly to a kind of novel knots of all-steel load-bearing radial tubeless tyre bead
Structure.
Background technique
With the fast development and progress of National Highway, all-steel load-bearing radial tire is also gradually from there is the inner tube of a tyre to nothing
Inner tube of a tyre upgrading and transformation, long-distance run at high speed can propose the requirement of more Gao Gengxin to the bead durability of tubeless tyre, but by
Tyre bead portion quickly give birth to by frequent stress, strain acting under the conditions of all-steel load-bearing radial tire is due to load and speed etc.
Splitting outside rim of the mouth and the beginning of fatigue failure problems such as bead chafing usually occurs in heat.Breakdown point is split outside rim of the mouth often appears in steel wire carcass
Near anti-package endpoint.The structure of domestic all-steel radial tyre is constantly brought forth new ideas and is developed in recent years, steady using wire bead infantees
Gu the big stress of steel wire carcass anti-package endpoint of the steel wire carcass in load, strain are to protect its carcass anti-package endpoint to disperse
The technology of stress also has great progress, but the stress of steel wire carcass anti-package endpoint is concentrated, big strain or safeguard measure do not obtain also
Thorough effective solution.
Summary of the invention
The purpose of the present invention is to solve disadvantages existing in the prior art, and a kind of all-steel load-bearing radial proposed
Tubeless tyre bead new structure.
To achieve the goals above, present invention employs following technical solutions:

The bottom of circle is provided with steel wire carcass, and the lower section of the steel wire carcass is successively closely fitted with steel bead wire infantees, the first nylon
Chafer, the second nylon chafer, the wear-resisting glue of liner layer and rim of the mouth, the first tri filling glue core and the second triangle are filled out
It fills on the outside of glue core and is provided with steel wire carcass, the liner layer is internally provided with steel bead wire infantees.
Preferably, the first nylon chafer and the second nylon chafer are coated on the outer of steel bead wire infantees
Side, the second nylon chafer are 10mm-20mm higher than the outer end point of the first nylon chafer, the first nylon tyre bead
Infantees is 15mm-30mm higher than the anti-package the outer end point of steel wire carcass, and the anti-package the outer end point of the steel wire carcass is than steel bead wire infantees
The high 10mm-20mm of the outer end point.
Preferably, it is provided between the first nylon chafer and steel bead wire infantees and slabs is isolated；In described
Stick on two endpoints for thering is film to be coated on steel bead wire infantees in the inside of lining.
Preferably, the anti-package cord of steel wire carcass is provided on the outside of the tri filling glue core.
Preferably, by the way that film progress is isolated between the anti-package the outer end point of the steel wire carcass and the first nylon chafer
It separates.
A kind of all-steel load-bearing radial tubeless tyre bead new structure proposed by the present invention, beneficial effect are:
1, since the height of two layers of nylon chafer is higher than steel wire carcass anti-package endpoint, steel wire carcass anti-package can be inhibited
Endpoint bring ess-strain when deformation of the tire under load is excessive, reduces the strain of steel wire carcass anti-package endpoint
Can, heat is reduced, the generation early stage bonding fatigue rupture between steel wire carcass anti-package endpoint and sizing material is effectively prevented.
2, increase by two layers of nylon chafer between wire loop and wheel rim, steel wire carcass is allowed firmly to be clipped in by wire loop
On wheel rim, reduce the strain energy that the ess-strain of deformation bring steel wire tire body end point of the tire under load generates, from
And tyre bead heat is also small, reduces and splits outside tyre bead rim of the mouth.
3, two layers of nylon chafer is covered in the anti-package part of wire bead infantees and steel wire carcass, steel wire component with
There is rigid transition between wheel rim, protects steel wire component the damage phenomenon such as not damage and bring bead chafing by wheel rim hard grind, improve tire
The mileage travelled service life.
