Document Type and Number:
WIPO Patent Application WO/2023/061511
Kind Code:
A1
Abstract:
A support rubber (1), and an internal self-supporting tire suitable for the whole series of passenger vehicles and a forming process for the internal self-supporting tire, which belong to the field of internal self-supporting tires. The support rubber (1) is in the shape of a trapezoid having a thickness of 4-12 mm; and the width of an upper base of the trapezoid is 0.5-1 mm. The support rubber (1) is used in a tire, and thus solves the technical problems of an existing internal self-supporting tire caused by the defects of a support rubber structure thereof, i.e. the existing internal self-supporting tire has a stress concentration under zero-air-pressure driving, and cannot take the durability performance under zero air pressure and the driving comfort performance under a normal tire pressure both into consideration, and the existing internal self-supporting tire cannot be applied to the whole vehicle series and thus has a small application range. The internal self-supporting tire has the characteristics of having a good zero-air-pressure durability performance and a good comfort performance and being suitable for the whole vehicle series.
