Description
Technical field
The utility model relates to a kind of all-steel load-bearing radial tire structures of double-deck body cord, are suitable for bearing capacity
The all-steel load-bearing radial tire of larger needs belongs to automobile tire technical field.
Background technique
With the development and progress of country, all-steel load-bearing radial tire using more and more, to the skeleton knot of tire
Structure and its lifting capacity propose the requirement of more Gao Gengxin, but since all-steel load-bearing radial tire skeleton structure is single, without too
Big technological innovation, for lifting capacity substantially there is no too big promotion, the cry that this promotes lifting capacity is higher and higher.
And China's overloading happens occasionally simultaneously, safety problem is not few caused by U-shaped explosion occurs because of overload rear tyre sidewall every year
Number, this to develop a tire construction bearing capacity, and to be substantially better than common heavy load radial tire imperative.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcomings, provide a kind of all steel load radial of double-deck body cord
Line tire construction is greatly decreased a possibility that U-shaped explosion occurs because of overload rear tyre sidewall, the carrying of tire greatly improved
Ability.
The technical solution of the utility model, the all-steel load-bearing radial tire structure of the double-deck body cord, including wire loop,
Cloth is encapsulated and upper bead filler for bead chafer, lower triangle rubber, shield；Lower triangle rubber is coated on the wire loop, is coated on lower triangle rubber
Upper bead filler, upper bead filler outer cladding shield cloth is encapsulated, and the encapsulated outside of shield cloth coats bead chafer；
It further include inner liner, transition zone, the first carcass ply, the second carcass ply；The cladding bead chafer with it is airtight
Layer is disposed adjacent, and transition zone is coated on the outside of inner liner, coats the first carcass ply, the first carcass ply outer cladding on the outside of transition zone
Second carcass ply.
It further include pad glue, tread slab base and tyre surface hat glue；Cladding pad glue and tyre surface base above second carcass ply
Portion's glue；Tyre surface is coated on tread slab base is preced with glue.
It further include the first belt, the second belt and third belt；Above second carcass ply from bottom to top
Set gradually the first belt, the second belt and third belt；First belt, the second belt and third banding
Layer both ends are successively coated and fixed by pad glue and tread slab base.
Length 30-40mm of the length of first carcass ply less than the second carcass ply.
The first carcass ply anti-package point and the second carcass ply anti-package endpoint form 15-20mm offset.
The endpoint of the third belt and the first belt and the second belt keeps unilateral 10-15mm offset.
The utility model eliminates steel wire heel fabric, then protects tyre bead portion by newly-increased body cord anti-package, takes
The double-deck 0 ° of belt that disappears is wound, although 0 ° of belt winding can improve the load-carrying properties of tire, tire greatly improved simultaneously
The heat of tread shoulder, tire are extremely easy to cause shoulder explosion because shoulder heat is excessively high in high load capacity high speed,
There are some potential safety problems, this improvement can effectively avoid problems.
Since the promotion of load-carrying properties is higher to the framework material intensity requirement at sidewall position, the skeleton at sidewall position is solved
Material strength problem is exactly to improve the intensity of body cord nothing but, first is that body cord individual wire intensity is improved, second is that improving
Body cord steel wire density, the former technology, cost requirement are high, and the latter improves single layer due to the limitation of current calendering technology
Body cord steel wire density feasibility is little.So effectively solving sidewall position all-steel cord by the structure of the double-deck body cord
Strength problem.A possibility that U-shaped explosion occurs because of overload rear tyre sidewall is greatly decreased, the carrying energy of tire greatly improved
Power.
The utility model has the beneficial effects that the utility model solves all-steel load-bearing radial tire because of tire caused by overloading
The U-shaped Blow-up Problems in side reduce tread shoulder heat, improve the load-carrying properties and its service life of tire, further improve
The security performance of tire.

Specific embodiment
As shown in Figure 1, the all-steel load-bearing radial tire structure of the double-deck body cord, including wire loop 1, bead chafer 2,
Lower triangle rubber 3, shield cloth encapsulated 4 and upper bead filler 5；Lower triangle rubber 3 is coated on the wire loop 1, coats upper three on lower triangle rubber 3
Angle glue 5,5 outer cladding of upper bead filler protect cloth encapsulated 4, and encapsulated 4 outside of shield cloth coats bead chafer 2；
It further include inner liner 6, transition zone 7, the first carcass ply 8, the second carcass ply 9；The cladding bead chafer 2 with
Inner liner 6 is disposed adjacent, and transition zone 7 is coated on the outside of inner liner 6, coats the first carcass ply 8, the first carcass on the outside of transition zone 7
8 the second carcass ply of outer cladding 9 of cord.
It further include pad glue 10, tread slab base 11 and tyre surface hat glue 12；Cladding pads glue 10 to second carcass ply 9 above
With tread slab base 11；Tyre surface is coated on tread slab base 11 is preced with glue 12.
It further include the first belt 13, the second belt 14 and third belt 15；Above second carcass ply 9 certainly
The first belt 13, the second belt 14 and third belt 15 are set gradually on down；First belt 13, the second band
Beam layer 14 and 15 both ends of third belt are successively coated and fixed by pad glue 10 and tread slab base 11.
Original double-deck 0 ° of belt winding shoulder cooperates triple layer belt beam layer structure, and tyre bead is protected by steel wire heel fabric.This
Utility model bilayer carcass cord structure is made of two layers of carcass connecting line construction, newly-increased 8 length Yue Bi of the first carcass ply
The short 30-40mm of two carcass ply 9 encloses position anti-package to raw steel silk heel fabric anti-package endpoint, with 9 anti-package end of the second carcass ply
Point forms about 15-20mm offset, replaces the effect of raw steel silk bead, protects tyre bead portion.
It can be also further added by heel fabric or nylon heel fabric in tyre bead portion, improve tire bead position intensity.Former tire
The double-deck 0 ° of belt of shoulders winding is cancelled, and widens third belt 15, makes itself and the first belt 13, the second belt 14,
Endpoint keeps unilateral 10 ~ 15mm offset.
First carcass ply 8 selects steel wire of the same race, and the more former body cord of steel wire arranging density can be slightly lower.Intensity of steel wire, rule
Lattice depend on the circumstances.
