Abstract
The prior radial ply tyres mostly adopt a wire- reinforced layer between a sub mouth glue and a carcass ply. However, the wire- reinforced layer has notable endpoint effect, thereby increasing the splitting trend of the sub mouth. In order to solve the problem, brand tyres add high performance reinforced layer at the endpoint or use high performance sub mouth glue and increase the thickness of the sub mouth. The disadvantages are increasing production cost and lowering production efficiency. Different from the prior radial ply tyres, the utility model is characterized in that the wire- reinforced layer is arranged between an apex rubber core and a carcass ply. The structure not only overcomes the endpoint effect of the reinforced layer, but also improves the rigidity of the sub mouth and prolongs the life span of the radial ply tyres; the use of high performance sub mouth glue is avoided, and the apex rubber core is used in production, and a wire loop and the wire- reinforced layer are compositely molded into one, thereby lowering wheel production cost and enhancing production efficiency.
Description
Technical field:
The utility model relates to a kind of motor tire, definitely says so to relate to a meridian line tyre.
Background technology:
General radial-ply tyre all is by bead coil, carcass cord, bracing ply constitutes tyre framework, and the tread-rubber by being shaped on decorative pattern, sidewall rubber, rim of the mouth glue, air/tight layer rubber, triangular rubber core form crown, tire shoulder, upper sidewall, lower sidewall, rim of the mouth and constitute tire, and rely on bead coil that tire is anchored on the wheel rim.Tire is in the ground connection rolling process of bearing load, and skeleton has born the internal stress more than 90%, and size differs widely and skeleton meets with stresses in above-mentioned segment identifier, has peak value at tire shoulder, the rim of the mouth first half.Stress concentration can bring strain energy to concentrate, in can changing into can and stress raiser is heated up, and with the skeleton contact be an an organic whole be polysulphide rubbers, the shortcoming that has thermal ageing, under long term high temperature, performance descends, tire shoulder, rim of the mouth easily produce delamination, particularly produce the rim of the mouth breach.Influence radial-ply tyre service life, in order to solve the rim of the mouth problem, major part is to increase a wirecord fabric enhancement Layer between the rim of the mouth at position, rim of the mouth glue and carcass cord at present, with increase rim of the mouth rigidity, share stress, reduce strain energy.Gu many international and domestic brand tires such as special, Michelin all adopt this structure.But there is significant end effect in the wirecord fabric enhancement Layer, promptly has very big stress at the end points place, and strain difference forms the ess-strain at end points place easily and concentrates, and makes rim of the mouth breach trend aggravation.For solving this association problem, the brand tire all adopts and increases the higher reinforcement adhesive tape of performance at the end points place or use performance-oriented rim of the mouth instead and protect glue at present, and increases the technical measures that glue thickness is protected in the rim of the mouth.Yet, increased the tire cost thereupon, also reduced tire production efficient.
Summary of the invention:
Goal of the invention of the present utility model is: overcome the shortcoming that above-mentioned radial tyre exists, for the user provides a kind of rim of the mouth intensity height, the built-in reinforcement radial ply tyre that use is durable, the materials cost is low, production efficiency is high.
Goal of the invention of the present utility model realizes by implementing following technical proposals: built-in reinforcement radial ply tyre, by bead coil, triangular rubber core, wrap up they the carcass cord, be arranged on the tyre framework that the bracing ply on its foreign steamer Zhou Fangxiang is formed, and wrap up crown that this skeleton forms by nexine air/tight layer rubber, outer tread-rubber, shoulder pad glue, sidewall rubber, rim of the mouth glue, tire shoulder, upper sidewall, lower sidewall, rim of the mouth and an organic whole formed, it is characterized in that: between carcass cord and triangular rubber core, be provided with steel wire infantees enhancement Layer; Additional technical feature of the present utility model is: triangular rubber core, bead coil and steel wire infantees enhancement Layer compound formable are parts, place in the carcass cord.
Advantage of the present utility model is: because steel wire infantees enhancement Layer is set between carcass cord and triangle glue, not only increase the rim of the mouth rigidity and reduced strain energy, and disperseed the stress of steel wire infantees enhancement Layer end points by the carcass cord, end effect has weakened, it is aging to have improved the rim of the mouth effectively, add simultaneously the probability that has reduced frictional failure between this enhancement Layer and carcass cord again, thereby improved effectively tire service life, and owing to do not use High Performance rim of the mouth glue, comparing with existing radial-ply tyre does not increase new parts yet, thereby has reduced cost; With bead coil, triangular rubber core, with the composite molding of steel wire infantees enhancement Layer be parts, can improve tire production efficient.
Description of drawings:
Fig. 1 is the utility model tire radial section structural representation
Fig. 2 is a tyre rim place structural representation
Mark among the figure: 1 is bead coil, and 2 is the carcass cord, and 3 is bracing ply, and 4 is tread-rubber, and 5 is sidewall rubber, 6 is rim of the mouth glue, and 7 is triangular rubber core, and 8 is shoulder pad glue, and 9 is air/tight layer rubber, and 10 is rim of the mouth steel wire infantees enhancement Layer, 11 is crown, and 12 is tire shoulder, and 13 is upper sidewall, and 14 is lower sidewall, and 15 is the rim of the mouth.
The specific embodiment:
The utility model is by bead coil 1, triangular rubber core 7 and 10 composite moldings of steel wire infantees enhancement Layer, its outer parcel by carcass cord 2 is formed tyre framework, inboard by air/tight layer rubber 9 parcels, rim of the mouth portion is by rim of the mouth glue 6 parcels, the outside is surrounded by sidewall rubber 5, the bracing ply top circumferentially is surrounded by tread-rubber 4, the shoulder pad place of bracing ply and carcass cord is surrounded by shoulder pad glue 8, form tyre cavity respectively, rim of the mouth 15, lower sidewall 14, upper sidewall 13, crown 11 and tire shoulder 12, they organically constitute whole tire body, and by bead coil 1 tire are anchored on the wheel rim.Because the place is provided with steel wire infantees enhancement Layer 10 in the rim of the mouth, therefore strengthened the rim of the mouth rigidity, reduced strain energy, prevented place, rim of the mouth ageing of rubber; Because steel wire infantees enhancement Layer 10 is arranged between carcass cord 2 and the triangular rubber core 7, disperseed the end points stress of steel wire infantees enhancement Layer 10 again, tested and show that this structure has weakened end effect significantly, helped improving tire service life by carcass cord 2.
