Description

A kind of radial air tire
Technical field
The present invention relates to tyre technologies, and in particular to a kind of radial air tire.
Background technique
Aircraft tyre is subjected to the extreme operation caused by combining due to the heavy load of aircraft with the high speed of aircraft Condition.Due to heavy load, tire bears the deflection bigger than passenger car or truck tyre.
There are two types of common constitutions for aircraft tire tool: oblique and meridian.Aircraft tire more than 80% is oblique, This indicates that they have the cover tire made of multi-layer intercrossed casing ply, and staggeredly casing ply is relative to circumferential line at substantially small In 90 degree of alternate angle.But since lighter weight is pursued by aircraft fuselage manufacturer, radial becomes more often See.
Current meridian aviation tyre is since carcass and belt cord angle are arranged in meridian direction, carcass line angle Degree is big, curtain cloth layer is few, sidewall is soft, in the case where bearing top load, large deformation case conditions in use, tyre bead portion is by very big Imposed deformation, promote rubber internal heat under viscoplasticity effect, tyre temperature caused to increase to be easy to happen tyre bead damage Bad phenomenon.The damage of tyre bead portion is generally close to wheel rim top, be easy carcass ply anti-package end and around rubber Interface generates removing；Or delamination or cord breakage phenomenon occur between the interface of wire loop or gum filler and casing ply. The endurance quality for thus greatly reducing tyre bead causes tyre bead delamination, bulge, tyre bead blasting phenomena even occurs when serious.
Thus, it is desirable to have one kind is antifatigue and resists the flexibility modified radial all enhanced.
Summary of the invention
In view of the deficiencies of the prior art mentioned above, the present invention provides with stronger antifatigue and resist flexibility boat Gap radial tire.
To achieve the above object, technical solution provided by the invention are as follows:
A kind of radial air tire, including tyre surface position, banding position, carcass position, inner liner, steel wire ring layer and tire It is preced with reinforcer, the tread band is bonded as one by the glue-line of different structure, between the tread band and inner liner successively It is provided with the steel wire ring layer and crown ply reinforcement of several wire loop compositions disposed in parallel, is passed through between multiple wire loops Wire is joined together to form steel wire, and gum filler is provided on the steel wire, and the crown ply reinforcement includes several First belt made of the carbon cellulose of parallelly distribute on, the two sides of first belt point are connected with the sidewall layer It connects, the end lap of the gum filler is on the junction of first belt and the sidewall layer, and the filling glue Item is connected with the contact surface of first belt by the strengthening course with organic fiber cord.
Further, wire loop core infantees is provided in the steel wire ring layer, the wire loop core infantees is with organic fibre Apex strip and wire loop are wrapped together by dimension cord.
Further, the tread band includes glue surface layer and the second belt, and setting is in the glue surface layer and the A low-heat type glue-line between two belts, second belt are made of carbon cellulose.
Further, second belt is four layers.
Further, the tread band with a thickness of 2-8mm, the width of the tread band is 20-60mm.
Further, the glue surface layer is made of rubber, and rubber composition includes following component by weight: oil-filled rubber 50-100 parts of glue, 10-40 parts of butadiene-styrene rubber, 20-30 parts of butadiene rubber, 10-30 parts of polyisoprene rubber, carbon black 10-40 Part, 1-8 parts of zinc stearate；50-60 parts of naphthenic rubber oil are wherein filled in every 100 parts of rubber.
Further, the molecular weight 500000-1000000 of the butadiene rubber.
A kind of radial air tire provided by the invention, it is several by being disposed between tread band and inner liner The design of a steel wire ring layer and crown ply reinforcement disposed in parallel to increase the mechanical performance of inside tires, and then reduces tire The generation of internal implosion, the effect that the promotion of tire quality is played a significant role.Meanwhile crown ply reinforcement and steel wire ring layer itself The design of structure is able to solve tire sidewall deformation greatly, and the low problem of lateral stiffness can prevent tyre bead portion from generating delamination, energy It enough prevents ply ends from generating cord relaxation delamination, and has stronger antifatigue and resist flexibility.
