Description
Technical field
The present invention relates to tyre technology, be specifically related to the tread rubber of a meridian line tyre.
Background technology
Radial is a kind of structure formation of tire, is different from bias tyre, arch type, adjustable inflation pressure tyre etc.
The cord arrangement of meridian tyre body is different from bias tyre, the cord of radial is not mutual cross arrangement, but with cover tire section close to parallel, as terrestrial meridian arrangement, cord angle is little, be generally 0 °, do not maintain intersection point between body cord, when tire in the process of moving, bizet ambient stress increase, circumference can be caused to uphold, carcass radial breach.Therefore the buffer layer of radial adopts the cord ply of coming into contacts with close to circumferential array, in 90 ° crossing with body cord angle, be generally 70 ° to 78 °, form a rigid annular shaped band almost can not upheld, whole tire is fixed, the circumferential deformation of restriction tire, this buffer layer bears the internal stress of whole tire 60% to 70%, become the main stressed member of radial, therefore be referred to as the belt of radial.The main stressed member of bias tire not on the buffer layer, bear by the cord body of carcass by its internal stress of 80% to 90%.As can be seen here, radial tire undertread design is very important, and must have good rigidity, can adopt multilayer wide-angle, high strength and the filamentary material not easily stretched, as steel wire or aramid fiber etc.Advantage is: contact area is large, and adhesion property is good, and tyre surface slippage is little, and also little to ground unit pressure, thus rolling resistance is little, long service life.Crown is thicker and have hard belt, not easily pierces through; Be out of shape little during traveling, oil consumption 3% ~ 8% can be reduced.Because curtain cloth layer is few, sidewall is thin, so its radial elastic is large, shock-absorbing capacity is good, and portative power is larger.Perfect heat-dissipating, can adapt to high temperature, run at high speed.
Tread rubber: outermost tyre layers contacts with road surface and surface prints a dapple layer sizing.Tire can be made to have tractive force, cushion impact when travelling and wave, preventing cutting and piercing through of cord ply.Require wear resistance, the fatigue performance with height, good ageing-resistant performance, higher tensile strength, elasticity and obdurability, and heat generation low when travelling.
The mechanical property of tread rubber of the prior art is desirable not enough, is further improved.
