0 degree belt edge filter of all steel radial tire and its preparation technique and tire using the same

Abstract

The invention relates to an all-steel wire radial ply tyre, in particular to an all-steel wire radial ply tyre with an improved 0 DEG belted layer structure. The invention discloses a 0 DEG belted layer of the all-steel wire radial ply tyre, which comprises a structure with a plurality of layers, wherein the same layer is formed by winding a steel wire which is extruded and coated with glue for multiple circles. The invention also discloses the all-steel wire radial ply tyre adopting the structure. The invention has the following advantages that: 1, because the whole 0 DEG belted layer is wound by a steel cord, the tension is even, the 0 DEG belted layer is neat, and stress concentration of the 0 DEG belted layer can be avoided; 2, because the whole 0 DEG belted layer is wound by the steel cord, no connecter exists, and the stress concentration and hidden air are not easily generated; and 3, only one steel cord spindle is needed, so a great number of spindles are saved; and the steel cord after extrusion does not need to be coiled firstly and then transported to the forming working procedure for unwinding and use, so a coiling apparatus, plastic laying cloth, a transportation facility and unwinding equipment are saved.

Description

technical field [0001] The invention relates to an all-steel radial tire, in particular to an all-steel radial tire with an improved 0° belt layer structure. Background technique [0002] Such as figure 2 As shown, the existing tire includes a table portion, a sidewall portion, a bead portion and a carcass layer, and the outer side of the carcass layer is sequentially 1# belt layer, 2# belt layer and 0 degree belt layer. As the most important structural design technology of all-steel radial tires, the 0-degree belt layer structure design has been widely adopted by many tire companies at home and abroad, especially more than 90% of domestic tire companies adopt this structure. The 0° belt layer is located above the 2# belt layer on the tire shoulder. In the prior art, several steel cords are extruded side by side and covered with rubber at the same time, coiled on the I-shaped wheel, then transported to the forming machine, and wound in two layers on the belt layer laminati...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a 0° belt layer of an all-steel wire radial tire, which can solve the tire shoulder damage caused by the stress concentration of the 0° belt layer and the joint harboring air caused by the prior art technical problems, while also simplifying the production process
