Embodiment Construction

[0012] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] Such as figure 1 As shown, there are two parts of reinforcement layers 31 and 32 between the belt layer 2 and the ply 4, which are symmetrical on the left and right sides, one end starts at the bead 5, and the other end ends at the tire crown, and the two parts reinforce Layers 31 and 32 are overlapped under the belt layer 2, and the overlapping portion accounts for 40% to 60% of the tread width, preferably 45% to 50%, and the thickness of each part of the reinforcing layers 31 and 32 is 3~ 5cm, made of high modulus mesh interwoven composite fibers.

[0014] The above are preferred emb...

Abstract

The invention relates to a radial tire. The radial tire comprises a tire tread, a belted layer, a cord fabric layer and a reinforcing layer which is arranged between the belted layer and cord fabric layer, the reinforcing layer is divided into two parts which respectively start at tire beads on two sides, end at a crown part and are overlapped on the crown part. By adopting the technical scheme, the tire crown and side walls are simultaneously protected, the strength of the crown part is enhanced, and the pierce preventing property is improved.

Description

technical field [0001] The invention relates to automobile tires, in particular to a puncture-resistant radial tire. Background technique [0002] At present, in radial tires, the method of increasing the number of belt layers is mostly used to improve the rigidity and strength of the tire. Some belt layers reach as many as 6 or 7 layers. Although this improves the wear resistance of the tire, in comparison, the performance of the sidewall is improved. If there is no corresponding improvement, it will become more and more fragile. Some tires adopt the method of adding a layer of reinforcing ribs, covering the carcass with a mesh structure made of steel wire or other composite fibers, so that the tire as a whole can be protected by an additional layer to prevent puncture and blowout. But this approach did not achieve the desired effect. Contents of the invention [0003] The object of the present invention is to provide a radial tire aimed at the defects of the prior art....
