Description

Technical Field

[0001] This utility model relates to the field of tire technology with special materials, specifically to a steel-plastic composite tire. Background Technology

[0002] Metal tires are a special type of tire primarily constructed of metal. Unlike traditional rubber tires, metal tires offer higher strength, greater stability, and better wear resistance. Generally, these tires may be entirely metal-based or incorporate metal in key areas to enhance performance. Solid metal tires have a simple structure, directly cast or forged from metal. Their advantages include high load-bearing capacity and virtually no risk of blowouts. Hollow metal tires may have a more complex structure, with internal space allowing for weight reduction through special designs.

[0003] In existing technologies, metal tires typically use an adhesive bonding method between the tread and the tire base. Localized damage necessitates replacing the entire tire, resulting in high costs and poor stability. Therefore, to address these issues, an assembled steel-plastic composite tire is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a steel-plastic composite tire. It uses replaceable components and can be assembled and disassembled as a whole. Individual components can be replaced according to the damage, without replacing the entire tire, thus extending the tire's service life and reducing usage costs. It has good anti-skid performance on unpaved and icy roads for heavy mining trucks, loaders, and special vehicles, and has good stability in use. It can reduce the wear and tear caused by the vehicle during operation and has high inventiveness and practicality.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a tread 1, a base 2, a base screw assembly 3, a tread screw assembly 4, anti-skid teeth 5, and a retaining ring 6; a matching base 2 is installed inside the tread 1, and there is a retaining ring 6 on each side surface of the tread 1 and the base 2; the base screw assemblies 3 on both sides pass through the two retaining rings 6 and are fixed to the base 2 in a through manner, and the tread screw assemblies 4 on both sides pass through the two retaining rings 6 and are fixed to the tread 1 in an insert manner; multiple evenly distributed anti-skid teeth 5 are installed on the surface of the tread 1.

[0006] Furthermore, the tread 1 has multiple evenly distributed tread screw holes 101 on both sides, and the tread screw assembly 4 is fixed to the tread 1 through the tread screw holes 101.

[0025] Furthermore, the tread 1 has multiple evenly distributed tread surface screw holes 102, and the anti-skid teeth 5 are fixed to the tread 1 surface through the tread surface screw holes 102. This allows for quick installation and removal of the anti-skid teeth 5 on the tread 1, and they can be removed individually according to the wear condition of each individual anti-skid tooth 5.

[0026] Furthermore, the tire base 2 has multiple evenly distributed tire base screw holes 201 on both sides. The tire base screw assembly 3 is fixed to the tire base 2 through the tire base screw holes 201. During the installation process, the screw in the tire base screw assembly 3 directly passes through the tire base 2 and is screwed in, so that the metal tire as a whole maintains high installation stability from the inside to the outside.

[0027] Furthermore, the tire base 2 is a combination structure of metal steel ring and polyurethane elastic elastomer material, and the tire base 2 has multiple uniformly distributed and identically shaped crescent grooves 202, which can provide heat dissipation assistance for the interior of the tire base 2 and improve the shock absorption effect of the tire.

[0028] Furthermore, the hardness of the tire base 2, which is a rubber component, is determined by the actual production and installation requirements.

[0029] Furthermore, both the tire base screw assembly 3 and the tire tread screw assembly 4 include an M14*35 flange spherical screw and an M14 flange spherical nut.

The base fixing hole 601 and the tread fixing hole 602 can be used to reinforce the screw connection between the tread 1, the base 2 and the fixing ring 6.

[0032] The working principle of this utility model is as follows: During installation, the base screw assembly 3 passes through the base fixing holes 601 on the fixing rings 6 on both sides and passes through the base screw holes 201 to be fixed at the half position of the base 2. The tread screw assembly 4 passes through the tread fixing holes 602 on the fixing rings 6 on both sides and is directly fixed to the tread screw holes 101 to form a whole tire. At the same time, multiple anti-skid teeth 5 that can be disassembled and installed immediately are installed on the surface of the tread 1. The installation direction of the anti-skid teeth 5 is determined according to the installation direction of the metal tire. The inner teeth 501 are located on the inner side of the metal tire, and the outer teeth 503 are located on the outer side of the metal tire, forming the anti-skid pattern of the metal tire. During maintenance, individual components can be replaced according to the damage.
