Description

Technical Field

[0001] This utility model relates to the field of tires, and more specifically, to a tire belt layer structure. Background Technology

[0002] In radial tires, the belt layer is located between the tire carcass and the tread. The part of the tread that contacts the ground is called the tread crown, which can buffer impacts and reinforce the tire. It is the main load-bearing component. Therefore, the strength and stiffness of the belt layer largely determine the load capacity of the pneumatic tire and the impact resistance of the tread crown. The load capacity of the tire and the impact resistance of the tread crown directly affect the safety of tire use.

[0003] The utility model patent with authorization announcement number CN 220465154 U discloses a belt layer structure for an all-steel radial truck tire in the field of tire belt layer structure technology. It includes a first belt layer and a second belt layer. The second belt layer is located outside the first belt layer and is fixedly connected to it. A Z-shaped crown strip is located outside the second belt layer. A third belt layer is located on one side of the Z-shaped crown strip. A fourth belt layer is located outside the third belt layer. The tire carcass is located inside the first belt layer, and an inner liner is located inside the tire carcass. Through the layered belt layers and the Z-shaped zero-degree winding structure, the problem of mismatched expansion coefficients between the belt layer and the steel crown strip is solved. The Z-shaped crown strip forms a hoop effect on the belt layer and the tire carcass, inhibiting radial expansion after tire inflation, reducing interlayer stress, and improving tire safety and service life.

[0004] In the above-disclosed structure, multiple layers of straps are directly stacked together and embedded into the tire. The lack of separate strap structures not only hinders zone positioning and affects accuracy, but also lacks wrapping and supporting straps. They cannot be stacked together, resulting in poor stability and low tightness of the interconnection, which reduces load capacity and needs to be improved. Utility Model Content

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a tire belt layer structure. By embedding a middle belt inside the tire body, the load-bearing capacity can be enhanced. Furthermore, by connecting the end belts and folded belts on both sides, combined with the first wrapping belt and the second wrapping belt for reinforcement, it can be connected in sections and then combined for reinforcement, ensuring accuracy and stability, facilitating production connection, effectively improving impact resistance and load-bearing capacity, and exhibiting high adaptability.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A tire belt layer structure includes a tire carcass, the outer surface of which is provided with a tread, a central belt fixedly embedded inside the tire carcass, end belts fixedly attached to both ends of the central belt, a bent portion at the middle of the end belt, a folded belt at one end of the bent portion, a first wrapping belt fixedly attached to one side of the outer surface of the folded belt, a supporting belt at one end of the first wrapping belt, one side of the supporting belt fixedly connected to the lower surface of the folded belt, the other side of the supporting belt fixedly attached to the outer surface of the central belt, and a second wrapping belt fixedly attached to one side of the outer surface of the end belt, the second wrapping belt fixedly connected to both sides of the end position of the central belt.

[0008] Furthermore, layered straps are fixedly attached to the middle positions of both sides of the outer surface of the intermediate strap, and a pressing strap is fixedly connected to one side surface of the layered strap.

[0009] Furthermore, the compression strap is fixedly connected to the outer surface of the layered strap, and the ends of the compression strap and the layered strap are fixedly connected to one end surface of the first wrapping strap.

[0010] Furthermore, a top strap is fixedly attached to the outer surface of the compression strap, and both ends of the top strap are fixedly attached to one side of the outer surface of the first wrapping strap. The layered strap and the compression strap are connected by the middle strap. The top strap on the combined surface can support and reinforce the middle position. In addition, the combination of the top strap and the top strap can enhance the connection stability at both ends, which is conducive to installation, connection and reinforcement, and ensures the pressure resistance effect.

[0011] Furthermore, there are four end straps and four first wrapping straps, all symmetrically distributed at the two ends of the two sides of the middle strap.

[0012] Furthermore, the second wrapping strap is symmetrically connected to both ends of the middle strap.

[0013] Furthermore, the first wrapping strap and the support strap are an integral structure and are bent and connected to the two sides of the folded strap. By symmetrically connecting the end straps and the first wrapping strap, and combining the second wrapping straps at both ends, they can be symmetrically connected to ensure the overall structural strength and stability and improve the support effect on the tire body.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution enhances the load capacity by embedding a middle strap inside the tire body. It also strengthens the tire by connecting the end straps and folding straps on both sides, combined with the first and second wrapping straps. It can be connected in sections and then combined for reinforcement, ensuring accuracy and stability, facilitating production connection, effectively improving impact resistance and load effect, and has high adaptability.

[0016] (2) The layered straps and the compression straps are connected by the middle straps and combined with the top straps on the surface, which can support and reinforce the middle position. Furthermore, the combination of the top straps and the top straps can enhance the connection stability at both ends, facilitate installation and connection reinforcement, and ensure the compressive strength.

[0017] (3) By symmetrically connecting the end straps and the first wrapping straps, and combining them with the second wrapping straps at both ends, they can be symmetrically connected to ensure the overall structural strength and stability and improve the support effect on the tire body.

A middle belt 12 is fixedly embedded inside the carcass 1. End belts 13 are fixedly attached to both ends of the middle belt 12. A bent portion 14 is provided in the middle of the end belt 13, and a folded belt 15 is provided at one end of the bent portion 14. One end of the broken belt 13 is fixedly attached to the surface of the middle belt 12, and then bent to form the bent portion 14 and the folded belt 15. Then, a first wrapping belt 16 is wrapped around both sides of the folded belt 15, forming a support belt 17 at the bottom, which is then fixedly attached to the surface of the middle belt 12. This structure can be connected in sections for combined reinforcement, ensuring safety, stability, and high adaptability.

The ends of the pressing strap 21 and the layered strap 2 are fixedly connected to one end surface of the first wrapping strap 16. A top strap 22 is fixedly attached to the outer surface of the pressing strap 21. Both ends of the top strap 22 are fixedly attached to one side of the outer surface of the first wrapping strap 16. The layered strap and the pressing strap are connected by the middle strap. The top strap on the combined surface can support and reinforce the middle position. Furthermore, the combination of the top strap and the top strap can enhance the connection stability at both ends, facilitate installation and connection reinforcement, and ensure the compressive strength.
