Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to a durable tire structure. Background Technology

[0002] A tire is a ring-shaped component mounted on the rim of a vehicle. As the only part of the vehicle in contact with the ground, it plays a crucial role in automotive engineering, primarily in bearing weight, providing traction and braking force, and absorbing vibrations.

[0003] Radial tires are generally required to have strong load-bearing capacity. However, some trucks need to be used frequently in long-distance transportation, and the tires may need to cope with various unexpected environments. Some existing tires only design the tread pattern, and the tire wear resistance is still insufficient. The wear is relatively serious, and the tires are prone to direct air leakage after being punctured. Therefore, this application proposes a durable tire structure. Utility Model Content

[0004] Based on the above description, this utility model provides a durable tire structure that solves the technical problems pointed out in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A durable tire structure includes an airtight layer, a tire carcass, a tread, and a sidewall, wherein a protective space is provided between the sidewall, the tread, and the tire carcass, and the durable tire structure further includes:

[0006] The belt structure is located in the protective space and is mounted on the tire carcass;

[0007] Wear-resistant protrusions are set on the tire surface;

[0008] A puncture-resistant liner is installed on the tire body, and the tread is installed on this puncture-resistant liner. The two sides of the puncture-resistant liner are in contact with the inner wall of the tire sidewall. The area between the puncture-resistant liner and the tire body is a belt area, and the belt structure is installed in this belt area.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the belt structure consists of three belt layers, namely a first belt layer, a second belt layer, and a third belt layer, which are arranged sequentially from the inside to the outside along the radial direction of the tire.

[0011] Furthermore, the first belt layer, the second belt layer, and the third belt layer are one of steel wire cord, aramid, nylon, or polyester fiber.

[0012] Furthermore, grooves are formed on the tire tread for drainage.

[0014] Furthermore, the tire body is disposed on the airtight layer, and the tire body is one of polyester cord or polyester fiber cord.

[0015] Furthermore, the puncture-resistant liner is made of butyl rubber.

[0016] Furthermore, an interlayer is provided between the airtight layer and the tire body, and a reinforcing structure is provided at the interlayer. The reinforcing structure includes a nylon sheath and a steel wire sheath, with the nylon sheath located on the inner wall of the steel wire sheath.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] This durable tire structure utilizes wear-resistant protrusions to provide excellent wear resistance, making the tire relatively less prone to wear.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] like Figure 1 and Figure 2As shown, a durable tire structure in this embodiment includes an airtight layer 1, a tire carcass 2, a tread 3, and a sidewall 4. There are two sets of sidewalls 4, which are disposed on both sides of this durable tire structure and fixed between the tread 3 and the outer side of the airtight layer 1. The tire carcass 2 is fixedly disposed on the airtight layer 1. In this way, the airtight layer 1 maintains the air pressure inside the tire and prevents gas leakage, thereby ensuring that the tire can work normally. The tire carcass 2 is one of polyester cord or polyester fiber cord. The above is the prior art and will not be described in detail here.

[0025] It should be noted that grooves are provided on the tread 3, with one side of the grooves extending toward the sidewall 4 for drainage.

[0026] Please see Figure 2 As part of the design of this application, the durable tire structure also includes a belt structure 5, wear-resistant protrusions 6, and puncture-resistant inner liner 7. In order to provide space support for the belt structure 5 and the puncture-resistant inner liner 7, a protective space is provided between the tire sidewall 4, the tire tread 3, and the tire body 2 in this embodiment, while the wear-resistant protrusions 6 are fixedly provided on the tire tread 3.

[0027] To ensure the puncture-resistant liner 7 is properly installed, in this embodiment, the puncture-resistant liner 7 is fixedly installed on the tire body 2, and the tire tread 3 is fixedly installed on the puncture-resistant liner 7. The two sides of the puncture-resistant liner 7 are fixedly attached to the inner wall of the tire sidewall 4. The area between the puncture-resistant liner 7 and the tire body 2 is a belt area, and the belt structure 5 is installed in this belt area.

[0028] In addition, an interlayer is provided between the airtight layer 1 and the carcass 2, and a reinforcing structure 8 is provided at the interlayer. The reinforcing structure 8 includes a nylon sheath 81 and a steel wire sheath 82. The nylon sheath 81 is located on the inner wall of the steel wire sheath 82 and is fixedly attached to the outer wall of the carcass 2. The inner wall of the steel wire sheath 82 is also fixedly attached to the outer wall of the carcass 2, and the outer wall is fixedly attached to the airtight layer 1, which is used to provide tensile strength and good elastic recovery performance.

[0029] In one embodiment, the belt structure 5 consists of three belt layers: a first belt layer 51, a second belt layer 52, and a third belt layer 53. The first belt layer 51, the second belt layer 52, and the third belt layer 53 are arranged sequentially from the inside to the outside along the radial direction of the tire. The first belt layer 51, the second belt layer 52, and the third belt layer 53 are made of steel cord, aramid, nylon, or polyester fiber. With this design, the belt structure 5 can buffer the stress and impact on the tire carcass 2, thereby improving the tire's load-bearing and durability performance.

[0030] In addition, in this embodiment, the puncture-resistant liner 7 is preferably made of butyl rubber. Because butyl rubber has extremely low gas permeability, it can effectively prevent air from leaking out of the tire. Butyl rubber also has good elasticity and recovery properties, and can quickly rebound and fill the damaged area even after being subjected to external force. This characteristic is particularly important for the self-healing function, because it ensures that even if a puncture occurs, the liner can fit tightly to the wound, prevent air from escaping quickly, maintain stable pressure inside the tire, and reduce safety hazards caused by sudden pressure loss. In addition, butyl rubber has good resistance to oxygen, ozone, and various chemicals, and is not prone to aging and becoming brittle, which helps to extend its service life and maintain a long-term stable puncture resistance.

[0031] In this embodiment, there are multiple wear-resistant protrusions 6, which are located on the tread 3 excluding the grooves and surround the outside of the tread 3. There is a gap between two adjacent wear-resistant protrusions 6, which is beneficial to meet the drainage requirements. It should be noted that the wear-resistant protrusions 6 are made of a material that is harder and more wear-resistant than the tread 3. A preferred design is, for example, rubber with silica added as a filler.

[0032] When silica is uniformly dispersed at the nanoscale in a rubber matrix, the nanoscale silica particles can form a stronger interaction with rubber molecules, increasing the overall structural stability of the material. This significantly enhances the mechanical strength and wear resistance of the rubber. In addition, silica is hydrophilic, which allows it to interact better with the water film on the road surface, helping to expel moisture and making the rubber adhere more tightly to the ground. Silica particles can also increase the micro-roughness of the rubber surface, which helps to form more physical engagement points on wet and slippery roads, thereby increasing the coefficient of friction and enhancing wet grip.

[0033] Working principle:

[0034] The designed wear-resistant protrusions 6 provide the tire with good wear resistance, making the tire relatively less prone to wear. In addition, the protective space is designed with a puncture-resistant liner 7, which can quickly rebound and fill the damaged area when a puncture occurs, complete the repair, prevent air from escaping quickly, maintain stable internal tire pressure, and thus reduce safety hazards caused by sudden pressure loss.

[0035] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
