Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically a full-steel irregular-shaped steel wire ring. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, the new energy vehicle market is experiencing unprecedented growth. To improve the driving range of new energy vehicles, tire lightweighting has become an important design direction. New energy vehicle tires reduce weight while maintaining performance, thereby reducing overall vehicle wear and tear.

[0003] The existing traditional all-steel radial truck tire has a regular hexagonal cross-sectional shape for its steel wire bead. The number of steel wire bead layers can be either odd or even. When the number of layers is odd, the widest layer is the centerline, and its cross-section is a regular axisymmetric hexagon. When the number of layers is even, its cross-sectional shape is approximately axisymmetric. The technical problem to be solved in this application is to provide an all-steel irregular-shaped steel wire bead structure design through optimized and innovative design of the tire steel wire bead structure, which reduces weight while optimizing the tire bead imprint to meet the current market development needs.

[0004] Based on this, we now provide an all-steel shaped wire ring that can eliminate the drawbacks of existing devices. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0022] In one embodiment, such as Figures 1-3 As shown, an all-steel irregular-shaped wire bead includes a wire bead body 1, with a composite rubber strip 2 wound around the outside of the wire bead body 1. The composite rubber strip 2 is spirally wound evenly on the outside of the wire bead body 1 without overlapping. Elastic protective rings 3 are provided at the outer and inner edges of the wire bead body 1. The arrangement of the wire bead body 1 is hexagonal irregular shape. The outer side of the elastic protective ring 3 contacts the tire carcass wires, and the inner side contacts the wire bead wires. This can effectively buffer and offset the impact force between the tire carcass wires of the wire bead, reduce the wear between the wire components, improve the service life of the tire, and improve safety. By adjusting the wire bead structure, the tire bead pressure is effectively optimized, and the tire bead durability is improved while optimizing the tire weight.

[0023] In one embodiment, such as Figure 2As shown, the wrapping gap of the composite rubber strip 2 on the steel wire ring 1 is 0-2mm.

[0024] In one embodiment, such as Figure 2 As shown, the composite rubber strip 2 is made by adding high thermal expansion polyethylene resin and rubber through rubber-plastic compounding. It is resistant to high temperature and can ensure that it still has high thermal expansion at a service temperature of 50 degrees Celsius.

[0025] In one embodiment, such as Figure 1 As shown, the bottom surface angle of the steel wire ring body 1 is 15°.

[0026] In one embodiment, such as Figure 2 As shown, the elastic protective ring 3 is made of hydrogenated styrene thermoplastic elastomer material, which has strong high temperature resistance and can remain undamaged at temperatures above 100 degrees Celsius.

[0027] In one embodiment, such as Figure 2 As shown, the diameter of the elastic protective ring 3 is the same as the diameter of the steel wire in the wire ring.

[0028] In one embodiment, such as Figure 2 As shown, the number of steel wire bead layers and the maximum number of wires vary with the shape, solving the problem of interference in the safety multiple design of the steel wire bead, and improving the durability of the bead while optimizing the tire weight.

[0029] The above embodiments disclose an all-steel irregular-shaped wire bead. When in use, after the finished wire bead is applied to the tire, one side of the elastic protective ring 3 contacts the tire carcass wire, and the other side contacts the wire bead wire. This can effectively buffer and offset the impact force between the tire carcass wire and the wire bead, reduce wear between the wire components, improve tire service life, and enhance safety. By adjusting the wire bead structure, the tire bead pressure can be effectively optimized, thereby improving tire bead durability while optimizing tire weight.

[0030] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
