Radial tire with twining type steel wire belted layer and manufacturing method thereof

Abstract

The invention relates to the field of radial tire manufacture, in particular to a radial tire with a twining type steel wire belted layer and a manufacturing method thereof. The radial tire comprises a tire surface, a belted layer and a tire side. The belted layer consists of a 1# belted layer, a 2# belted layer, a 3# belted layer, a 4# belted layer and a 0# belted layer, wherein the 1# belted layer is arranged at the bottom and serves as a transition layer, the 2# belted layer and the 3# belted layer are sequentially arranged above the 1# belted layer, the 4# belted layer is arranged above the 3# belted layer, the width of two ends of the 2# belted layer is larger than that of the 1# belted layer, the 0# belted layer is twining type wirecord fabric which is identical with the circumferential direction of the tire, and the 0# belted layer is symmetrically attached to two sides of the 1# belted layer and under the 2# belted layer through a twining method. The radial tire with the twining type steel wire belted layer can effectively avoid deformation of shoulders of tires, optimize stress of the belted layers and pressure distribution of ground connection of the tire surface, improve durability, wear-resisting property and loading capacitance and reduce oil consumption.

Description

technical field [0001] The invention relates to the field of radial tire manufacturing, in particular to a radial tire adopting a wound steel wire belt layer structure and a manufacturing method thereof. Background technique [0002] The design of the belt structure of the tire will affect the performance and service life of the tire. Therefore, it is very important to design a belt structure with high performance and long service life. At present, in the application of the belt layer structure of the radial tire, there are mainly: a structure with a 0-degree belt layer such as figure 1 shown) and a 4-layer belt structure without a 0-degree belt structure such as figure 2 shown) two. [0003] 0 degree belt layer structure: 1# belt layer 5 and 2# belt layer 6 are the working layer mainly responsible for the circumferential force of the tire, usually the strength of the steel wire is higher) 1# belt layer 5 and the circumferential direction usually form 24 degrees with the ...

AI Technical Summary

Problems solved by technology

However, the stress in the belt layer area below the zero-degree belt layer is too large, and it is not conducive to retreading. After some patterns are applied, groove bottom cracks are prone to occur, which greatly reduces the service life of the tire. Its application is limited and its advantages cannot be achieved. fully use
