Description

Technical Field

[0001] This utility model relates to the field of tire structure and performance optimization technology, and in particular to a high-strength puncture-resistant vacuum tire. Background Technology

[0002] With the development of the transportation industry, the performance requirements for tires are becoming increasingly stringent. Especially in complex road conditions, such as construction sites and mines, tires need to possess excellent puncture resistance to reduce the occurrence of blowouts and other malfunctions, thereby improving vehicle safety and efficiency. Traditional tubeless tires have certain limitations in puncture resistance, relying solely on a single layer of rubber or a simple reinforcing structure to resist punctures. When encountering sharp objects such as gravel or rebar, they are prone to localized damage, leading to slow leaks or even blowouts. This not only increases repair costs but also disrupts work progress due to mid-journey stops, making it difficult to meet the needs of these special scenarios.

[0003] However, existing high-strength, puncture-resistant tubeless tires have the following drawbacks: Traditional tubeless tires rely on a single rubber layer for puncture resistance, making them easily punctured by sharp objects, leading to blowouts or slow leaks.

[0004] Therefore, this invention provides a high-strength, puncture-resistant vacuum tire. Utility Model Content

[0005] (a) Technical problems to be solved The problem solved by this utility model is to provide a high-strength, puncture-resistant vacuum tire with high practicality, which solves the problem mentioned in the background art that the puncture resistance relies on a single rubber layer and is easily punctured by sharp objects.

[0006] (II) Technical Solution To achieve the above objectives, this utility model is implemented through the following technical solution: a high-strength puncture-resistant vacuum tire, comprising a tire body, wherein the tire body is provided with an airtight layer, a puncture-resistant layer, a skeleton layer and a wear-resistant layer from the inside to the outside, the puncture-resistant layer comprising a steel wire mesh layer woven from steel wire, and the wear-resistant layer having an anti-slip layer on its surface.

[0007] Optionally, the inner wall of the airtight layer is provided with sound-absorbing cotton. The sound-absorbing cotton is circular in shape and is made of sound-absorbing and sound-insulating materials. It is circular and attached to the inner wall of the airtight layer. It can absorb the resonance noise generated by the vibration of the air inside the tire, as well as the high-frequency noise transmitted to the interior when the tire body rubs against the road surface.

[0008] Optionally, two mounting rings are fixedly connected to both sides of the skeleton layer. The two mounting rings are fixed to both sides of the skeleton layer, corresponding to the groove structure on the edge of the wheel hub. When the tire is installed, the tight engagement between the rings and the wheel hub prevents the tire from shifting relative to the wheel hub during high-speed rotation, rapid acceleration, or emergency braking.

[0009] Optionally, the surfaces of the wear-resistant layer and the anti-slip layer are provided with three drainage grooves. When driving on rainy days or roads with standing water, the drainage grooves on the surfaces of the wear-resistant layer and the anti-slip layer can quickly drain the water in the contact area between the tire and the ground, avoiding slippage caused by water blocking the direct contact between the tire and the ground.

[0010] Optionally, the airtight layer is made of butyl rubber material with a thickness of 2 to 3 mm. Butyl rubber has a dense molecular structure and extremely low gas permeability, making it the core material of the airtight layer of a vacuum tire. The 2 to 3 mm thickness design ensures lightweight while providing sufficient structural strength to resist internal air pressure impact and prevent slow gas leakage.

[0011] Optionally, the wear-resistant layer is made of a blend of natural rubber and styrene-butadiene rubber, wherein the content of natural rubber is 40% to 60% and the thickness of the wear-resistant layer is 5 to 8 mm. Natural rubber provides excellent elasticity and tear resistance, while styrene-butadiene rubber enhances wear resistance and aging resistance. The blend of the two can balance the hardness of the tread, ensuring appropriate deformation when in contact with the road surface to increase friction, and resisting rubber wear caused by long-term friction.

[0012] (III) Beneficial Effects This invention provides a high-strength, puncture-resistant tubeless tire with the following advantages: This high-strength, puncture-resistant tubeless tire features a puncture-resistant layer composed of steel wire mesh. The high strength of the steel wires forms a rigid protective barrier, and their metallic properties directly resist the initial impact of sharp objects. When a sharp object contacts the tire, the interwoven structure of the steel wire mesh quickly disperses the puncture force to the surrounding mesh, preventing a single point from being breached due to stress concentration. At the same time, its own hardness forms a physical barrier, preventing the object from penetrating further into the tire body. In addition, the tight fit between the steel wire mesh layer and adjacent structural layers forms a seamless, three-dimensional protection, making it difficult for puncture objects to find weak gaps, thus effectively blocking the penetration of sharp objects and greatly improving the tire's puncture resistance.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Please see Figures 1 to 4 This utility model provides a technical solution: a high-strength puncture-resistant vacuum tire, comprising a tire body, which, from the inside out, is provided with an airtight layer 1, an anti-puncture layer 2, a skeleton layer 3, and a wear-resistant layer 5. It is mainly made of materials with excellent airtightness, and its function is similar to a sealing cover, effectively preventing gas leakage inside the tire. After the tire is inflated, the airtight layer 1 can maintain stable internal air pressure for a long time, reducing the inconvenience of frequent inflation and ensuring that the tire is always at normal working pressure, thereby ensuring the safety and stability of vehicle operation. The anti-puncture layer 2 includes a steel wire mesh layer 4 woven from steel wires, which is the key line of defense against punctures. The steel wire mesh layer 4 is woven from high-strength steel wires. The steel wires themselves have high hardness and strength. When encountering sharp objects, the steel wire mesh layer 4 can directly block the intrusion of sharp objects due to the rigidity of the steel wires, preventing them from puncturing the inside of the tire. The wear-resistant layer 5 has an anti-slip layer on its surface. The inner wall of the airtight layer 1 is provided with sound-absorbing cotton 7. The sound-absorbing cotton 7 is circular in shape and is made of sound-absorbing and sound-insulating material. It is circular and attached to the inner wall of the airtight layer 1. It can absorb the resonance noise generated by the vibration of the air inside the tire, as well as the high-frequency noise transmitted to the inside when the tire body rubs against the road surface. Two mounting rings 6 are fixedly connected to both sides of the skeleton layer 3. The two mounting rings 6 are fixed to both sides of the skeleton layer 3, corresponding to the groove structure of the wheel hub edge. When the tire is installed, the tight engagement between the rings and the wheel hub prevents the tire from shifting relative to the wheel hub during high-speed rotation, rapid acceleration or emergency braking. The wear-resistant layer 5 and the anti-skid layer have three drainage grooves on their surfaces. When driving in rainy weather or on roads with standing water, the drainage grooves on the surfaces of the wear-resistant layer 5 and the anti-skid layer can quickly drain the water in the contact area between the tire and the ground, preventing the tire from slipping due to water blocking the direct contact between the tire and the ground. The airtight layer 1 is made of butyl rubber material. The thickness of the airtight layer 1 is 2 to 3 mm. The butyl rubber has a dense molecular structure and extremely low gas permeability. It is the core material of the airtight layer 1 of the vacuum tire. The 2 to 3 mm thickness design ensures lightweight while providing sufficient structural strength to resist internal air pressure impact and prevent slow gas leakage. The wear-resistant layer 5 is made of a blend of natural rubber and styrene-butadiene rubber, with the natural rubber content being 40% to 60% and the thickness of the wear-resistant layer 5 being 5 to 8 mm. Natural rubber provides excellent elasticity and tear resistance, while styrene-butadiene rubber enhances wear resistance and aging resistance. The blend of the two can balance the hardness of the tread, ensuring appropriate deformation when in contact with the road surface to increase friction, and resisting rubber wear caused by long-term friction.

[0017] In this invention, the working steps of the device are as follows: Steps: The airtight layer 1 is made of materials with excellent airtightness, such as butyl rubber; when the tire is filled with compressed air, the molecular structure of the airtight layer 1 is compact, making it difficult for gas molecules to penetrate; the steel wire mesh layer 4 in the puncture-resistant layer 2 is woven from high-strength steel wire, which has extremely high tensile strength and rigidity; when the tire is punctured by a sharp object such as a nail or gravel, the steel wire mesh layer 4 comes into contact with the sharp object first; the skeleton layer 3 is generally made of multiple layers of cord woven at a specific angle; providing the tire with basic shape and support; the wear-resistant layer 5 is made of rubber material with excellent wear resistance, and its molecular structure has good wear resistance properties; during the long-term friction between the tire and the ground, the wear-resistant layer 5 material can resist wear, reduce the wear of the rubber on the tire surface, and thus extend the tire's service life.
