Between carcass ply.
Further, the tyre bead includes steel ring complex, the compound external surface of steel ring successively anti-package tyre steel wire carcass
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# belt and 3# belt set gradually, in 1# banding
The both ends setting pad glue of layer, 2# belt and 3# belt, is arranged tyre surface in 1# belt, 2# belt and 3# banding layer surface
Base rubber and tyre surface are preced with glue.
All-steel load-bearing radial tire structure described in the utility model solves all-steel load-bearing radial tire finished product tire tire
In naked wire or tyre cavity the problems such as showing line and other issues, solving the U-shaped explosion in sidewall, improve the load-carrying properties and its use of tire
Service life further improves the security performance of tire；Replace simultaneously and revealed transition layer sizing, nylon heel fabric, reduces processing
Process reduces molding procedure laminating step, improves production efficiency, reduces material cost.

Specific embodiment
Below with reference to specific attached drawing, the utility model is described in further detail.
As shown in Figure 1, all-steel load-bearing radial tire structure described in the utility model includes tyre surface, sidewall 4, connection tyre surface
With the tire shoulder on sidewall 4, it is connected to the tyre bead and skeleton structure of 4 lower part of sidewall, the skeleton structure is by layer of steel wire carcass
5, one layers of nylon bag layer of cloth 6 of cloth 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；
The tyre bead includes the steel ring complex that wire loop 16, upper bead filler 11 and lower triangle rubber 14 are constituted, the compound external surface of steel ring
Successively anti-package tyre steel wire carcass 5 and steel wire heel fabric 15,5 anti-package of tyre steel wire carcass to 15 anti-package end of steel wire heel fabric
At the outer about 15mm of point, 15mm or so offset is formed, replaces former transition zone effect, inner liner sizing material is protected not flow into steel wire tire
Body cord 5, while replacing the protection tyre bead of the turn-up position of protection 15 anti-package endpoint of 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# belt 2 and 3# belt 3 set gradually, in 1# belt 1,2# band
Tyre surface is arranged on 1# belt 1,2# belt 2 and 3 surface of 3# belt in setting pad glue 8 in the both ends of beam layer 2 and 3# belt 3
Base rubber 9 and tyre surface are preced with glue 10.
All-steel load-bearing radial tire structure described in the utility model, by layer of steel wire body cord and one layer of nylon infantees
The skeleton structure of layer eliminates the transition zone between inner liner and carcass ply, then is replaced by newly-increased nylon bag layer of cloth, and
Anti-package protects tyre bead portion.
The utility model has the advantage that 1, since the framework material intensity at sidewall position is wanted in the promotion of load-carrying properties
Ask higher, the framework material strength problem for solving sidewall position is exactly the intensity for improving body cord nothing but, first is that improving carcass
Cord individual wire intensity, second is that improving body cord steel wire density, the former technology, cost requirement are high, and the latter is due to current
It is little to improve single layer body cord steel wire density feasibility for the limitation of calendering technology.So passing through layer of steel wire body cord
The structure of one layer of nylon bag layer of cloth is added effectively to solve sidewall position all-steel cord strength problem.It is greatly decreased because of the rear tyre tire that overloads
A possibility that U-shaped explosion, occurs for side, and the bearing capacity of tire greatly improved.
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 instead of transition zone with nylon bag layer of cloth
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, tyre bead portion and steel wire rim of the mouth, carcass are can effectively protect
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.
