Abstract
It the utility model is related to tire manufacturing techniques field, specifically, be a kind of different polymer fiber materials and agricultural tyre, including tyre surface, ply structure, sidewall and wire loop structure, wire loop structure is packaged in tire in glue, glue is packaged in ply structure in tire, ply structure is packaged in tread rubber, it is characterized in that, casing ply is arranged to outer casing ply and interior casing ply according to position, outer casing ply uses nylon cord fabrics, interior casing ply uses polyester cord, compared with traditional detail design, the utility model can be avoided because carcass material shrinks at high temperature, elongation is big and durable, agricultural tyre caused by heat resistance difference comes to nothing, cracking problem, and then improve life-span and the endurance quality of agricultural tyre.
Description
Technical field
Tire manufacturing techniques field is the utility model is related to, is that a kind of different polymer fiber materials are used in combination specifically
Agricultural tyre.
Background technology
Tire is mainly by carcass, cushion（Belt）, tyre surface, sidewall composition, on wheel rim, by wheel rim branch
Hold, support vehicle body, buffer foreign impacts.
Domestic production carcass material is more based on nylon cord or polyester cord at present, and nylon cord has intensity
The advantages that height, hydroscopicity is low, heat resistance, wearability, and flexible resistance is good, but shrinkage factor and elongation are larger under high-temperature condition, wheel
Tire is in inflation in use, carcass deformation greatly, easily causes finished product cracking；Polyester cord has intensity high, high-modulus, lower shrinkage, returns
The advantages that elasticity is good, but heat-resisting and endurance quality is poor, and easily causing finished product during tire used blows out, comes to nothing.Domestic agricultural wheel at present
Tire there are problems that coming to nothing, cracking, has had a strong impact on the service life of tire, has reduced the endurance quality of agricultural tyre.
Utility model content
In order to solve the above-mentioned technical problem, the utility model disclose a kind of different polymer fiber materials and agricultural
Tire, concrete technical scheme are as follows：
A kind of different polymer fiber materials and agricultural tyre, including tyre surface, ply structure, sidewall and wire loop
Structure, wire loop structure are packaged in tire in glue, and glue is packaged in ply structure in tire, and ply structure is packaged in tread rubber
Interior, casing ply is arranged to outer casing ply and interior casing ply according to position, and outer casing ply uses nylon cord fabrics, and interior casing ply is using poly-
Ester cord.
Further improvement of the utility model, the nylon cord fabrics extension value that outer cord layer choosing uses 1.025-1.035 it
Between, the polyester cord extension value that interior casing ply uses is between 1.020-1.025.
Further improvement of the utility model, roll tension force when outer casing ply rolls between 560Kg-1380Kg,
Roll tension force during interior casing ply calendering between 400Kg-880Kg
Further improvement of the utility model, outer casing ply finished product Guan Jiao is between 48 ° -55 °, interior casing ply finished product Guan Jiao
Between 48 ° -55 °.
The purpose of this utility model is that solve agricultural tyre to come to nothing and be cracked quality problems.Because agricultural tyre has speed
Low, the features such as load is small, the influence of cord heat resistance and endurance quality to agricultural tyre is little, therefore carries out nylon to agricultural tyre
Polyester cord simultaneously uses design studies.Agricultural tyre progress fractograph analysis result of coming to nothing is paid compensation for according to market, agricultural tyre comes to nothing
Between tyre surface and outer layer cord, because bizet and shoulder deform heat to agricultural tyre when in use, with agricultural tyre
Long-term use of bizet and shoulder heat gradually increases, and causes tyre surface to decline with outer layer cord interlayer adhesion, so as to cause to come to nothing.
Be this outer layer cord from the small nylon cord fabrics of heat, roll when nylon cord fabrics roll tension force 560Kg-1380Kg it
Between, outer layer curtain cloth cutting angle is adjusted, ensures outer layer nylon cord fabrics presumed stretch ratio between 1.025-1.035, finished product Guan Jiao
Between 48 ° -55 °, can effectively solve agricultural tyre finished product caused by deforming heat and come to nothing, while internal layer cord uses Gao Mo
The polyester cord of lower shrinkage is measured, rolls tension force when polyester cord rolls between 400Kg-880Kg, adjustment internal layer cord is cut out
Angle of rupture degree, ensure internal layer polyester cord presumed stretch ratio between 1.020-1.025, finished product Guan Jiao, can be between 48 ° -55 °
Reduce the contraction distortion after tire depanning, suppress the carcass expansion during tire used, reduce agricultural tyre decorative pattern root
Stress concentration, can effectively solve agricultural tyre cracking symptom, while improve the anti-wear performance of tire.The method is ensuring that tire is whole
In body performance basis, reasonable selection ectonexine cord species, reduce casing ply heat and reduce the deformation after tire depanning, reduce
Decorative pattern Root Stress is concentrated, and solution is come to nothing, be cracked quality problems.
The beneficial effects of the utility model：Agricultural tyre speed is low, and load is small, is designed by reasonable construction, interior casing ply
Using polyester cord, outer casing ply uses nylon cord fabrics, can give full play to nylon cord fabrics intensity height, and hydroscopicity is low, heat resistance,
The advantages that wearability, flexible resistance is good and polyester cord intensity is high, high-modulus, lower shrinkage, and resilience is good, so as to solve agriculture wheel
Tire comes to nothing, cracking problem, improves Life of Tyre.Compared with traditional detail design, the method can be avoided due to carcass material
Agricultural tyre caused by material shrinks at high temperature, elongation is big and durable, heat resistance is poor comes to nothing, cracking problem, and then improves
The life-span of agricultural tyre and endurance quality.
