Description
Technical field
The present invention relates to a kind of all-steel load-bearing radial tire structures, belong to all-steel load-bearing radial tire technical field.
Background technology
With the development and progress of country, the application of all-steel load-bearing radial tire is more and more, to the skeleton knot of tire
Structure and its lifting capacity propose the newer requirement of higher, but since all-steel load-bearing radial tire skeleton structure is single, without too
Big technological innovation, substantially there is no too big promotions for lifting capacity, this makes the cry that lifting capacity is promoted higher and higher.
And China's overloading happens occasionally simultaneously, safety problem is not being lacked caused by U-shaped explosion occurs for overload rear tyre sidewall every year
Number, it is imperative better than common heavy load radial tire that this to develop a tire construction bearing capacity.
Invention content
The purpose of the present invention is overcoming the deficiencies in the prior art, a kind of all-steel load-bearing radial tire knot is provided
Structure solves the strength problem of the framework material at sidewall position, reduces because the possibility of U-shaped explosion occurs for overload rear tyre sidewall
Property, the bearing capacity of tire greatly improved.
According to technical solution provided by the invention, the all-steel load-bearing radial tire structure, including tyre surface, sidewall, company
The tyre bead and skeleton structure for connecing the tire shoulder of tyre surface and sidewall, being connected to lower sidewall, it is characterized in that：The skeleton structure is by one
Layer tyre steel wire carcass, one layer of nylon bag layer of cloth and inner liner are constituted, and nylon bag layer of cloth is filled in inner liner and steel wire cord tire
Between cloth.
Further, the tyre bead includes steel ring complex, the compound external surface of steel ring anti-package tyre steel wire carcass successively
With steel wire heel fabric, tyre steel wire carcass anti-package to steel wire heel fabric anti-package endpoint outer end forms the disconnected of certain distance
Difference.
Further, encapsulated in the turn-up position outer surface of tyre steel wire carcass cladding bead chafer and shield cloth.
Further, the steel ring complex is made of wire loop, upper bead filler and lower triangle rubber.
Further, outside the tyre steel wire carcass anti-package to steel wire heel fabric anti-package endpoint at about 15mm.
Further, the tyre surface includes the 1# belt, 2# belts and 3# belts set gradually, in 1# bandings
The both ends setting pad glue of layer, 2# belts and 3# belts, is arranged tyre surface in 1# belts, 2# belts and 3# banding layer surfaces
Base rubber and tyre surface are preced with glue.
All-steel load-bearing radial tire structure of the present invention solves all-steel load-bearing radial tire finished product tire tyre cavity dew
Line or tyre cavity show line and other issues, the problems such as solving the U-shaped explosion in sidewall, improve the load-carrying properties of tire and its use the longevity
Life, further improves the security performance of tire；Replace simultaneously and revealed transition layer sizing, nylon heel fabric, reduces processed
Journey reduces molding procedure laminating step, improves production efficiency, reduces material cost.

Specific implementation mode
With reference to specific attached drawing, the invention will be further described.
As shown in Figure 1, all-steel load-bearing radial tire structure of the present invention includes tyre surface, sidewall 4, connection tyre surface and tire
The tire shoulder of side 4, the tyre bead and skeleton structure for being connected to 4 lower part of sidewall, the skeleton structure by layer of steel wire carcass ply 5,
One layer of nylon bag layer of cloth 6 and inner liner 7 are constituted, and nylon bag layer of cloth 6 is filled between inner liner 7 and tyre steel wire carcass 5；It is described
Tyre bead includes the steel ring complex that wire loop 16, upper bead filler 11 and lower triangle rubber 14 are constituted, and the compound external surface of steel ring is successively
Anti-package tyre steel wire carcass 5 and steel wire heel fabric 15, outside 5 anti-package of tyre steel wire carcass to 15 anti-package endpoint of steel wire heel fabric
At about 15mm, 15mm or so offset is formed, replaces former transition zone effect, inner liner sizing material is protected not flow into steel wire cord tire
Cloth 5, while replacing the protection bead part of the turn-up position of 15 anti-package endpoint of protection steel wire heel fabric and tyre steel wire carcass 5
Position；Cladding bead chafer 13 and shield cloth encapsulated 12 in the turn-up position outer surface of the tyre steel wire carcass 5.
The tyre surface includes the 1# belt 1,2# belts 2 and 3# belts 3 set gradually, in 1# belts 1,2# bands
Tyre surface is arranged on 1# belts 1,2# belts 2 and 3 surface of 3# belts in setting pad glue 8 in the both ends of beam layer 2 and 3# belts 3
Base rubber 9 and tyre surface are preced with glue 10.
All-steel load-bearing radial tire structure of the present invention, by layer of steel wire body cord and one layer of nylon bag layer of cloth
Skeleton structure eliminates the transition zone between inner liner and carcass ply, then is replaced by newly-increased nylon bag layer of cloth, and anti-package
Protect tyre bead portion.
The present invention has the following advantages：1, due to the promotion of load-carrying properties to the framework material intensity requirement at sidewall position compared with
Height, the framework material strength problem for solving sidewall position is exactly the intensity for improving body cord nothing but, first, improving body cord
Individual wire intensity, second is that improving body cord steel wire density, the former technology, cost requirement are high, and the latter due to rolling at present
It is little to improve single layer body cord steel wire density feasibility for the limitation of technique.So adding one by layer of steel wire body cord
The structure of layer nylon bag layer of cloth effectively solves sidewall position all-steel cord strength problem.It is greatly decreased because of overload rear tyre sidewall hair
The possibility of raw U-shaped explosion, greatly improved the bearing capacity of tire.
2, since inner liner contains butyl rubber and steel wire bond properties is very poor so between inner liner and carcass ply often
Prevent inner liner from entering metal-cord using transition zone, the invention serves as excessive layer with nylon bag layer of cloth instead of transition zone
Effect, and be also possible to prevent air/tight layer rubber when sizing material abnormal flow or material distribution insufficient and enter metal-cord,
It effectively prevent tyre cavity to show line or naked wire and other issues.
3, outside due to inner liner anti-package to steel wire rim of the mouth endpoint, can effectively protect tyre bead portion and steel wire rim of the mouth, carcass
The anti-package endpoint position of cloth, while casing ply has covered steel wire rim of the mouth positive closure endpoint position, can effectively prevent rim of the mouth implosion.
4, since nylon bag layer of cloth is using one layer of entirety, instead of original transition zone, the positive turn-up position in rim of the mouth is protected
The materials such as nylon rim of the mouth can reduce process, reduce molding procedure laminating step, improve production efficiency, reduce cost.
