Abstract
The invention provides a radial tire with belt work ply cords arranged at 90 degrees in the circumferential direction. The radial tire is characterize in that the lower side of a shoulder wedge is connected with a carcass ply, the upper side of the shoulder wedge is connected with a first belt ply and tread rubber respectively, sidewall rubber is connected with the side surface of the tread rubber, and both the first belt ply and a second belt ply are arranged at 90 degrees. According to the radial tire, a section curve is usually parallel to a tread design curve; the work plies circumferentially arranged at 90 degrees are orthogonal to a carcass at 0 degree in the radial direction, and basic features of an orthogonal tire are formed. Compared with existing various steel wire belt ply structures, the radial tire has the advantages that the maximum value of the strain energy density in rubber parts in a crown area is reduced by 50%-80% and is moved to an area near the shoulder surface greatly beneficial to heat radiation from space among the belt plies or end areas on two sides, and the mass loss problems such as early shoulder separation, crown separation, separation, crown burst and the like which usually occur easily during use of a tire adopting the radial tire structure can be effectively solved.
Description
Technical field
The present invention relates to a kind of with bundle working lining cord circumferentially 90 degree of radial-ply tyres arranged, belong to radial-ply tyre technical field.
Background technology
Carcass ply, bead coil and bracing ply constitute the basic framework of radial-ply tyre.At present except the radial-ply tyre of few special purpose adopts lamination coating to make except bracing ply, the overwhelming majority all adopts steel cord to make, comprise semi-steel radial tire and all-steel radial tyre, no matter its dimensions size, all there is one deck or which floor steel belt, when radial ply tire angle is considered as 0 degree, the angle of each bracing ply is between 25 to 85 degree, and particularly under tyre inflating state, the peripheral force more than 70% born restrainted by band is that the working lining being 65 degree to 75 degree by angle is born; Be furnished with the steel belt of one deck 90 degree in some belt structure, or on band bundle working lining two ends, arrange that the 90 degree band bundles of width about with bundle beam overall 1/4th are two-layer; The bracing ply of this 90 degree obviously only helps out whole band is intrafascicular.The belt structure of this angular cross is when tire running, there is shear strain in interlayer, particularly between two-layer working lining edge, rubber components shearing stress strain amplitude is large, heat-dissipating is high, heat radiation is difficult, and mechanical properties of rubber compound declines, normal delamination restrainted by easily appearance band, shoulder is empty, causes the early stage matter damage of tire.In order to alleviate this shearing stress concentration problem, the effective ways usually adopted are, between band bundle working lining two edges, add a wedge type doubling.
Summary of the invention
The object of the invention is to solve above-mentioned prior art Problems existing, namely the belt structure of angular cross is when tire running, there is shear strain in interlayer, particularly between two-layer working lining edge, rubber components shearing stress strain amplitude is large, heat-dissipating is high, heat radiation is difficult, mechanical properties of rubber compound declines, normal delamination restrainted by easily appearance band, shoulder is empty, causes the early stage matter damage of tire.And then provide a kind of with bundle working lining cord circumferentially 90 degree of radial-ply tyres arranged.
The object of the invention is to be achieved through the following technical solutions:
A kind of with bundle working lining cord circumferentially 90 degree of radial-ply tyres arranged, comprise: inside liner, casingply, ground floor bracing ply, second layer bracing ply, third layer bracing ply, tread-rubber, shoulder wedge and sidewall rubber, described inside liner, casingply, ground floor bracing ply, second layer bracing ply, third layer bracing ply and tread-rubber are connected in turn from inside to outside, the downside of described shoulder wedge is connected with casingply, the upside of shoulder wedge is connected with tread-rubber with ground floor bracing ply respectively, described sidewall rubber is connected with the side of tread-rubber, described ground floor bracing ply and second layer bracing ply are 90 degree of arrangements.Described casingply is 0 degree of arrangement.Described third layer bracing ply is 0 degree of arrangement.
Radial ply tyre steel wire band bundle working lining of the present invention is 90 degree of arrangements, is two-layer (also can be one or more layers); Two-layer bracing ply can be wide or not wide; Be typically two-layer 90 degree of wide designs, its sectional curve is general parallel with tread design curve; Circumferential array and carcass 0 degree of meridian of this 90 degree of working linings, to orthogonal, it constitutes the essential characteristic of orthogonal tire.For the cross bending rigidity of adjustment belt bundle, working lining can add auxiliary steel belt one deck, two-layer or multilayer, but first-selected 0 degree of arrangement; When tire running, each metal-cord interlaminar shear stress can be reduced to ultimate attainment by this orthogonal belt structure, compared with existing various steel belt structure, crown zone rubber components internal strain energy density maxima declines 50 ~ 80%, and strain energy density maxim between bracing ply or two side ends Head Section move away to the tire shoulder near-surface region very favourable to heat radiation, the matter damage difficult problem such as effectively can solve that the early stage shoulder that usual radial-ply tyre structure tire in use easily occurs is empty, hat sky, delamination, hat are quick-fried.When auxiliary steel belt adopts other angular array, the peripheral force that the working lining that should meet 90 degree of arrangements is born is not less than 70% of the total power of bracing ply circumference, to play the advantage of orthogonal tire construction of the present invention.
