Technical field
The present invention relates to a kind of Pneumatic belt tire, is a kind of anti-puncture and the strong radial-ply tyre of shock resistance more specifically.
Background technology
For air-inflation tyre, truck tyre particularly, anticyclonic pressure, high load capacity and under complicated, abominable road conditions, move often.Tyre surface position colloid is easily stabbed and is produced breach or fall piece, causes the bracing ply steel wire exposed, and the tire belt performance is descended, and is subjected to impacting the hour wheel fetal hair at crown and gives birth to explosion, causes the tire infantile failure, even causes major traffic accidents.For the load capacity that improves autotruck and the service life of tire, the anti-puncture ability that must the reinforced tire tyre surface and the bulk strength and the safety multiple at crown position.At present, be the whole shock resistance of anti-puncture performance and crown position that improves tyre surface, adopt adjust that tread-rubbers are joined or (with) method that increases crown groove base portion glue thickness carries out, but the raising of each performance more than the tire is produced effects and not quite, and often reduced the high speed performance of tire and increased tire weight and cost.
Summary of the invention
The purpose of this invention is to provide a kind of puncture-resistant inflating radial tire, the anti-puncture ability of this kind tire protector and crown position single-piece impact resistance all promote significantly.
The present invention for achieving the above object, the technical solution of employing is:
Puncture-resistant inflating radial tire, it comprises: a circumferential hoop is around the tyre surface of taking turns crown part, symmetry is on the sidewall of tire both sides, two tyre beads and extend in two tyre beads and walk around tyre bead laterally from inboard anti-package, thus the tyre skeleton that a pair of anti-package partial sum is positioned at the tyre bead inboard formed; The crown position is provided with the bracing ply that is formed by the steel cord calendering between the corresponding main body framework with it of tyre surface; Be provided with an interlayer in the described tyre surface, this interlayer is metal-cord or fibre curtain layer of cloth.
Above-mentioned tyre surface is compound tyre surface, and being divided into is three layers, and upper strata and lower floor are the epoxy glue bed of material, and interlayer is metal-cord or fibre curtain layer of cloth.
The lower thickness of above-mentioned tyre surface is between 0.5～10 millimeter, and intermediate layer thickness is between 0.5～6 millimeter.
Lower floor's epoxy glue bed of material, wire of intermediate layer carcass plies or the fibre curtain layer of cloth of above-mentioned tyre surface and 100% Stress at definite elongation of the upper strata epoxy glue bed of material change from high to low.
The stand out level of the interlayer of above-mentioned tyre surface and bracing ply is more than 5 millimeters, and the interlayer width is less than the tread surface width more than 5 millimeters.
The fiber and the tire equator of the steel wire of above-mentioned metal-cord or fibre curtain layer of cloth are angled, and this angle value is between 10～55 degree.
Above-mentioned steel wire or fiber become cross arrangement with the steel cord of the bracing ply the superiors.
Beneficial effect of the present invention:
1, the tyre surface of this kind puncture-resistant inflating radial tire is compound tyre surface, increases metal-cord or fibre curtain layer of cloth in the tyre surface, has strengthened the anti-puncture ability and the crown position single-piece impact resistance of tyre surface, and prolonged the service life of tire greatly.
2, the interlayer of tyre surface is metal-cord or fibre curtain layer of cloth, and after the tyre surface upper strata was by puncture, interlayer can play a protective role to tyre surface lower floor and bracing ply, has prolonged the service life of tire greatly.
3,100% Stress at definite elongation of lower floor's epoxy glue bed of material, wire of intermediate layer carcass plies or the fibre curtain layer of cloth of tyre surface and the upper strata epoxy glue bed of material changes from high to low, and the graded of Stress at definite elongation makes carcass have rational hardness and elasticity.
Description of drawings
Fig. 1 is the cross section view of puncture-resistant inflating radial tire;
Fig. 2 is the enlarged view of the first half among Fig. 1.
The present invention is described in detail below in conjunction with accompanying drawing:
The specific embodiment
In conjunction with Fig. 1, Fig. 2, puncture-resistant inflating radial tire, it comprises: a circumferential hoop is around the tyre surface 1 of taking turns crown part, symmetry is on the sidewall 2 of tire both sides, two tyre beads 3 and extend in two tyre beads 3 and walk around tyre bead laterally from inboard anti-package, thus the tyre skeleton 4 that a pair of anti-package partial sum is positioned at the tyre bead inboard formed.The crown position is provided with the bracing ply 5 that is formed by the steel cord calendering between the corresponding main body framework 4 with it of tyre surface 1.Described tyre surface 1 is compound tyre surface, and being divided into is three layers, and upper strata 101 is the epoxy glue bed of material with lower floor 103, and interlayer 102 is metal-cord or fibre curtain layer of cloth.Lower floor's 103 epoxy glue bed of materials, interlayer 102 metal-cords or the fibre curtain layer of cloth of tyre surface 1 and 100% Stress at definite elongation of the upper strata 101 epoxy glue bed of materials change from high to low.
The upper strata 101 epoxy glue bed of materials of tyre surface 1 are the also composite structure of multiple blend glue stuff of single blend glue stuff, and width, thickness are determined according to tire size and tire tread trench depth and base portion glue thickness.This layer is extruded by extruder.
Lower floor's 103 thickness of tyre surface 1 are 0.5,5.5 or 10 millimeter, and width determines according to tire size, and this layer is extruded by extruder or flattening mill rolls severing behind the film.
The compound of tyre surface 1 can carry out before tire building, also can be in forming process bracing ply fit on make-up machine, to apply ointment or plaster successively according to the order on tyre surface lower floor 103, interlayer 102, upper strata 101 after finishing and finish.
Contrast experiment's example:
The tyre model that compares experiment is 12.00R20-18PR, and its tyre surface 1 is a three-layer composite structure, and tire of the prior art, tyre surface are conventional colloid face.Other position structure and the material of two tires are identical, now carry out following experiment:
1) tire high speed performance test
Adopt a Tire testing drum, the experiment tire is installed in one and is of a size of on 8.5 the standard rim, fill with standard pressure and load standard load, linear velocity with 60 kilometers/hour under 38 ℃ environment is a starting velocity, every two hours speed increases by 10 kilometers, the running tire till this damaged tyres, writes down its operating speed value this moment.In table 1, test results is with an exponential representation, the tire a reference value 100 that this index is produced with prior art, and this index is high more, and the tire high speed performance is good more.
2) anti-puncture performance of tire protector and crown strength test
Anti-puncture performance of tire protector and the strength test of crown position, in table 1, test results is with an exponential representation, the tire that this index is produced with prior art is an a reference value 100, this index is high more, and the whole shock resistance of anti-puncture performance of tyre surface and crown is high more, and safety factor is big more.
