Description

Technical Field

[0001] The invention relates to the technical field of special material tires, and in particular to a steel-plastic composite tire. Background Art

[0002] Metal tires are a special type of tire that is mainly made of metal materials. Unlike traditional rubber tires, metal tires have higher strength, stability in use, and wear resistance. Generally speaking, this type of tire may be an all-metal structure, or metal materials may be used in key parts to enhance the performance of the tire. Solid metal tires have a simple structure and are directly made of metal casting or forging. Its advantages are strong load-bearing capacity and almost no blowouts. Hollow metal tires may be more complicated in structure. They have a certain amount of space inside and can reduce weight through some special designs.

[0003] In the prior art, the tread and the tire base of metal tires are usually bonded, and local damage requires the replacement of the entire tire, which is costly and has poor stability. Therefore, an assembled steel-plastic composite tire is proposed to solve the above problems. Summary of the invention
