Problems solved by technology

[0002] At present, the belt layer structure of all-steel radial tires generally has the thickness of the shoulder of the belt layer higher than that of the middle part, resulting in uneven ground contact pressure and abnormal wear, or the strength of the middle part of the crown is high, but the strength of the shoulder part is low, and shoulder voids are prone to occur , flat tire problem

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing:

[0019] like figure 1 , figure 2 As shown, the all-steel radial tire with the structure of separating the outer belt layer and the zero-degree belt layer includes three layers of belt layers arranged in the middle of the tire crown and zero-degree belt layers 4 arranged on the two tire shoulders , the three-layer belt layer is that the inner layer belt layer 1, the middle layer belt layer 2 and the outer layer belt layer 3 are sequentially arranged in the middle of the tire crown along the radial direction from the inside to the outside, and the two tire shoulders One layer of zero-degree belt layer 4 or two layers of zero-degree belt layer 4 arranged radially from the inside to the outside are all arranged on the top of each other. The zero-degree belt layer 4 is all wound along the circumferential direction, and the outer belt layer 3 and the two The zero-degree belt la...

Abstract

The invention discloses a full steel radial tire with a separated outer belt ply and zero degree belt ply structure. The radial tire comprises a three belt plies arranged in the middle of the tire crown and one or two zero degree belt plies arranged on two tire shoulders. Three belt plies comprise an internal belt ply, a middle belt ply, and an outer belt ply, which are arranged on the middle of the tire crown in sequence from inner to outer along the radial direction of the tire crown. Two tire shoulders are both provided with one zero degree belt ply or two zero degree belt plies, which arearranged in sequence along the radial direction from inner to outer. The distance between two radial edges of the outer belt ply and the zero degree belt plies of two tire shoulders is greater than 6mm. The tire has the advantages that the tire can be tightly fastened, the deformation of the edges of the outer belt ply is reduced, the shearing of the zero degree belt plies is relieved, the durability and high speed performance of the radial tire are enhanced effectively, and raw materials such as rubber, steel wire, cords, and the like, can be saved.

Description

Technical field [0001] The present invention relates to the field of tire structure technology, in particular to an all-steel radial tire with a separate outer belt layer and zero-degree belt layer structure. Background technique [0002] At present, in the belt structure of all-steel radial tires, it is common that the thickness of the shoulder of the belt is higher than that of the middle, resulting in uneven ground pressure and abnormal wear, or the strength of the middle part of the crown is higher, but the strength of the shoulder is low, and shoulder voids are prone to occur. , tire blowout problem. How to effectively avoid the shortcomings of the above two belt layer structures has become an urgent technical problem that needs to be solved. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide an all-steel radial tire with a separate structure for the outer belt layer and the zero-degree...
