Tire transition layer structure

Abstract

The invention relates to a tire transition layer structure which comprises a tire transition layer and an airtight layer. A first nylon woven cloth rubber piece and a second nylon woven cloth rubber piece are arranged symmetrically on two sides of the tire transition layer and arranged at a position of 40-70 mm away from a central line of the tire transition layer. The tire transition layer structure is simple in structure and compact in design; by arranging the first nylon woven cloth rubber piece and the second nylon woven cloth rubber piece, steel wire exposure in a tire due to nonuniform local stress at a position, with small curvature radius, on the lower portion of a tire shoulder is effectively reduced, U-shaped bursting of the tire in the process of use is reduced, and quality of the tire is improved.

Description

technical field [0001] The invention relates to a tire transition layer structure, which belongs to the technical field of tire design. Background technique [0002] At the lower part of the all-steel radial tire shoulder, the inner side of the carcass is close to the transition layer and the inner liner, and the outer side is the sidewall or pad rubber. Due to the small radius of curvature at this position, during the tire building and vulcanization process, the position where the carcass is subjected to tension tends to move, and there are symptoms of steel wire leakage in semi-finished and finished tires. Tires with slight wire leaks are very dangerous in use, and are likely to cause tire blowouts, causing serious safety hazards; tires with severe wire leaks become waste products, reducing the profit of the enterprise and causing a waste of resources. [0003] The mooney of the compound rubber is low, the size of the parts is unqualified, the molding positioning is not a...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the carcass under the shoulder of the tire has a small radius of curvature, and the position of the carcass under the action of tension tends to move during the molding and vulcanization process, resulting in steel wire leakage. It provides a simple structure and compact design. The transition layer structure of the tire can disperse the stress of the carcass under the shoulder on the transition layer and the airtight layer, and reduce the phenomenon of steel wire leakage in the tire
