[0022] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0023] In one embodiment, as Figures 1 - 3 shown, a lightweight high-load all-steel radial tire bead part design structure includes a carcass 4 and a wire wrap 10. A tightening ring 12 is provided at the bottom of the carcass 4. One side of the wire wrap 10 is directly wrapped on the tightening ring 12 through shaping rubber 9. The inside of the tightening ring 12 is turned back and buckled with a soft triangular rubber core 8 to improve the load-bearing capacity of the bead part, reduce the materials of the bead part, and lower the weight of the tire.

[0024] In one embodiment, as Figure 3As shown, the bead wire 11 is divided into two parts. The clamping ring 12 passes through the middle of the bead wire 11 and is turned back to one side of the bead wire 11. The bead wire 11 clamps the clamping ring 12, thereby improving the load-bearing capacity of the bead part and preventing the carcass 4 from being pulled back.

[0025] In one embodiment, as Figure 2 shown, the carcass 4 is adhered with a belt layer 2 through cushion gum 3 for buffering impacts.

[0026] In one embodiment, as Figure 2 shown, the outer surface of the belt layer 2 is provided with a tread crown 1, that is, the tread, which is the part of the tire in contact with the road surface.

[0027] In one embodiment, as Figure 2 shown, the inner wall of the carcass 4 is provided with an inner liner 5.

[0028] In one embodiment, as Figure 2 shown, the outer surface of the carcass 4 is evenly coated with sidewall soft gum 6 for reducing the weight of the tire, lowering fuel consumption, and reducing heat generation at the same time.

[0029] In one embodiment, as Figure 3 shown, a rabbet reinforcing gum 7 is provided at the turned-back end points of the clamping ring 12 and the bead wrapper 10 for protecting the turned-back end points of the clamping ring 12 and the bead wrapper 10 and ensuring that the durability performance of the tire is not affected.

[0030] Working principle: The above embodiments disclose a bead part design structure of a lightweight high-load all-steel radial tire. Among them, in use, the bead wire 11 is divided into two parts, so that the clamping ring 12 passes through the middle of the bead wire 11 and is turned back to one side of the bead wire 11. The bead wire 11 can clamp the clamping ring 12, thereby improving the load-bearing capacity of the bead part and preventing the carcass 4 from being pulled back. The outer surface of the carcass 4 is evenly coated with sidewall soft gum 6, which can reduce the weight of the tire, lower fuel consumption, and reduce heat generation at the same time. One side of the bead wrapper 10 is directly wrapped on the clamping ring 12 through the shaping gum 9. The soft triangular gum core 8 is turned back and buckled inside the clamping ring 12, which can improve the load-bearing capacity of the bead part, reduce the materials of the bead part, and lower the weight of the tire.

[0031] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed in the present application, and all should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
