Description

Technical Field

[0001] The utility model relates to the technical field of tires, in particular to a tire support structure. Background Art

[0002] At present, all-steel radial truck and bus tires were mainly introduced by Michelin Company of France in the 1950s. The structure of all-steel radial tires includes tread, base rubber, belt layer, carcass, soft triangle rubber, hard triangle rubber, bead wear-resistant rubber, sidewall rubber, airtight layer, transition layer, etc. After nearly 70 years of development, all-steel radial rubber tires have obvious advantages in terms of performance, fuel consumption, etc., and are currently widely promoted globally.

[0003] The manufacturing steps of all-steel radial rubber tires are as follows: first, the rubber compound is kneaded in an internal mixer, then each component is produced by extrusion or calendering, the components are compounded by a molding machine to produce a tire blank, and finally the finished tire is obtained by vulcanization in a vulcanizer. Simply put, it is the three main steps of component production, tire blank forming, and tire blank vulcanization.

[0004] The overall forming process of the tire blank is complex, requiring high precision and high equipment costs. Usually, during the forming process of rubber tires, the carcass needs to be pre-coated with rubber and cut, and then the carcass is reverse-wrapped, and the process is relatively complex.

[0005] During the vulcanization process of rubber tires in a vulcanizing tank, the final shaping is completed through the extrusion of molds and capsules. Tire molds are divided into tread molds and sidewall molds, which are fixed in the vulcanizer. In the following patents CN110561979B, CN210591242U, CN110948764B, and CN211364159U, the tire production process using casting technology has greatly simplified the tire manufacturing process. Especially the process adopted in CN110561979B, which has significantly reduced production costs, production processes, and fixed assets. In actual production, although the overall process has been simplified, the tire structure assembly (patent ZL202111540463.3) shows the disadvantages of complex manufacturing processes, complex assembly, and poor buffering performance, seriously affecting the production rhythm. Based on the foregoing patented technologies, this patent uses a more convenient tire support structure, which has the advantages of simple manufacturing process, easy assembly, strong support, and excellent buffering performance, and can greatly improve work efficiency. In extreme cases, such as when the external polymer is damaged, lacks air, or has a flat tire, this support structure does not affect the tire's load-bearing capacity and can continue to be used; the overall structure assembled with the pressure-bearing ring (see patent ZL202110613676.8), the installation ring (see patent ZL202210766780.5), and the rim can be directly used as a tire;

[0006] Therefore, it is necessary to provide a new type of tire support structure to solve the above technical problems. Summary of the Utility Model

The tire support structure according to claim 1, characterized in that: The material of the elastic columnar structure (2) may be a metal material, a non-metal material, an organic polymer material, or a composite material; The elastic columnar structure (2) can be made of different materials into a single-layer or multi-layer structure, or can be made of a single material into a single-layer or multi-layer structure.

6. The tire support structure according to claim 1, characterized in that: Functional holes can be processed on the surface of the elastic columnar structure (2), and the shape of the holes is circular, semicircular, or elliptical; the elastic columnar structure (2) can be made into a shape with two sides bulging outwards; the interior of the elastic columnar structure (2) can be made hollow to arrange a cooling circulation device; the elastic columnar structure (2) can extend out of the tire tread body on both sides to contact the ground, thereby increasing the overall strength and grip of the tire and enhancing heat dissipation.
