Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Such as figure 1 and figure 2 As shown, the sidewall portion of the radial tire with a dual-chamber sidewall structure according to the present invention includes an outer sidewall 1 and an inner sidewall 6, the inner sidewall 6 is located on the inner side of the outer sidewall 1, the outer sidewall 1 and the inner sidewall There is a closed hollow cavity 2 between the sidewalls 6, that is, the present invention adds a cavity 2 to the original sidewall part, so that the tire has an outer sidewall 1 and an inner sidewall 6. After the cavity 2 is added, there are two sidewalls on the sidewall of the tire, namely the outer sidewall 3 and the inner sidewall 4. When the tire is hit or punctured during driving, only the outer sidewall 3 is damaged, ensuring Ensure that the inner sidewall 4 is not damaged or slightly damaged, which ensures the drivi...

Abstract

The invention relates to the field of radial tires, in particular to a radial tire with a dual-cavity sidewall structure. The radial tire is provided with sidewalls, and the sidewalls comprise the outer sidewall and the inner sidewall. The inner sidewall is located on the inner side of the outer sidewall. Sealed hollow cavities are formed between the outer sidewall and the inner sidewall. Each sidewall of the tire is provided with two tire enclosures, namely the outer tire enclosure and the inner tire enclosure. A toothed supporting structure is arranged in each cavity and comprises a plurality of protrusions arranged at intervals. The side wall of each protrusion is of a withdrawal angle, and the withdrawal angles of every two adjacent protrusions are opposite. The radial tire is simple in structure, the sidewalls are effectively protected, the heat dissipation performance of the tire is improved, the high-speed durability of the tire is improved, and the service life of the tire is prolonged.

Description

technical field [0001] The invention relates to the field of radial tires, in particular to a radial tire with a double-cavity sidewall structure. Background technique [0002] At present, the existing sidewall design tires often have bulges and punctures during driving, and the heat dissipation is not good during high-speed driving, resulting in high-speed performance degradation or even tire blowouts. Claims rate increases, thus affecting the development of enterprises. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problems in the prior art, and propose a radial tire with a double-chamber sidewall structure, which has a simple structure, can effectively protect the sidewall, improve the heat dissipation performance of the tire, and improve the performance of the tire. High-speed durability and extended tire life. [0004] The technical solution of the present invention is: a radial tire with a double-cavity side...
