Description

Technical Field

[0001] This utility model relates to the field of tire technology, and more specifically, to a wear-resistant and explosion-proof tire. Background Technology

[0002] Tires are the core component of a vehicle that comes into contact with the ground, directly affecting the vehicle's driving performance, safety, and fuel efficiency. Their core value lies in providing good grip, wear resistance, and comfort through optimized tread design, material selection, and structural layout. However, with the automotive industry's increasing demands for energy conservation, environmental protection, intelligence, and high performance, traditional tires face many challenges in terms of material performance, structural design, and functional integration.

[0003] Run-flat tires are designed by incorporating materials such as mesh steel wires and hemp ropes into the rubber tire blank during manufacturing to increase the tensile strength when the tread is damaged. When the tire is punctured by a foreign object or subjected to extremely strong impact, the local pressure is extremely high due to the very small force-bearing area. In this case, the supporting force of the rubber tread is insufficient to resist the external pressure, resulting in poor run-flat performance. After the tire is punctured or subjected to severe impact, the internal air leaks out rapidly, and the tire deflates quickly. This causes the tire's supporting force to drop rapidly, making it unable to continue supporting the weight of the vehicle and rendering it unable to continue driving. Existing tires, on the other hand, are in contact with the ground for a long time during use, generating friction. Common tires usually rely on tread patterns to prevent slippage, but after prolonged use, most of the tread patterns will be damaged by friction, causing the tire tread to directly contact the ground. This makes the tire prone to slippage due to the damaged tread pattern, which can no longer maintain good friction and anti-slip characteristics. This seriously affects the tire's anti-slip performance during use. Utility Model Content

[0008] The present invention is further configured such that the inner support column is provided with symmetrical support cavities, and the support cavity is provided with a one-way valve to facilitate the inflation of the support cavity.

[0009] The present invention is further configured such that limiting rings are provided on both sides of the inner support column, and the limiting rings are snapped onto the wheel rim to restrict the direction of the inner support column.

[0010] The present invention is further configured such that the protective layer includes a nylon mesh layer, a high-density rubber layer, an adhesive layer, and a tire skin layer.

[0029] Please see Figures 1-5 A wear-resistant and explosion-proof tire includes a tire body 1, which includes a rim 2. An outer tire 3 is mounted on the rim 2. An inner support column 4 is positioned between the rim 2 and the outer tire 3. A fixing tube 5 is fixed between the inner support columns 4. A connecting tube 6 is provided between the fixing tube 5 and the inner support columns 4. Air outlet pipes 7 are connected to both sides of the inner support columns 4 via the connecting tube 6. An air inlet pipe 8 is also provided on one of the inner support columns 4 via the connecting tube 6. A protective layer 9 is provided on the inner side of the outer tire 3, and an anti-slip sleeve 10 is provided on the outer side of the outer tire 3. Anti-slip blocks 11 are provided on the anti-slip sleeve 10. The anti-slip block 11 has anti-slip protrusions 12. The inner support column 4 has symmetrical support cavities 13 inside. The support cavity 13 has a one-way valve 14. The inner support column 4 has limit rings 15 on both sides. The limit rings 15 are snapped onto the rim 2. The protective layer 9 includes a nylon mesh layer 16, a high-density rubber layer 17, an adhesive layer 18, and a tire skin layer 19. The nylon mesh layer 16 is tightly attached to the inner wall of the outer tire 3. The high-density rubber layer 17 is pasted on the inner wall of the nylon mesh layer 16. The inner side of the high-density rubber layer 17 is connected to the tire skin layer 19 through the adhesive layer 18.

[0030] In this embodiment, during use, the inner support column 4 is fixedly connected via the fixing pipe 5. Air is injected into the support cavity 13 of the inner support column 4 through the one-way valve 14. The inner support column 4 and the rim 2 are then inserted into the outer tire 3. The sealing between the rim 2 and the outer tire 3 employs existing technology, such as a sealing strip. Air is pumped into the intake pipe 8, and through the connecting pipe 6 and the outlet pipe 7, air is pumped into the air chamber of the outer tire 3. The intake pipe 8 is then blocked by the valve core. In the event of a puncture or burst in the outer tire 3, the air in the support cavity 13 of the inner support column 4 provides sufficient support, thus facilitating the continued use of the tire body 1. The inner support column 4 is positioned between the tire 3 and the rim 2 by limiting the ring 15. A protective layer 9 composed of multiple materials is pasted on the inner surface of the tire 3. When the surface of the tire 3 is punctured or damaged by impact, the nylon mesh layer 16 and high-density rubber layer 17 inside the protective layer 9 buffer the impact and tearing force at the moment of impact. Under the pulling action of the nylon mesh layer 16, further damage to the surface of the tire 3 is prevented. The adhesive layer 18 slowly seeps in to repair the tire, thereby extending the service life of the tire 3. The tire skin layer 19 isolates and prevents air leakage, thus playing a role in explosion prevention and explosion resistance.

[0031] Please see Figures 4-5 As one embodiment of the anti-slip sleeve 10 and the anti-slip block 11: the anti-slip block 11 includes a base layer 20, the inner side of the base layer 20 is provided with a first wear-resistant layer 21 and a second wear-resistant layer 22, the base layer 20 is provided with a third wear-resistant layer 23 and a high-temperature resistant layer 24, the anti-slip sleeve 10 includes a first hard rubber layer 25 and an air rubber layer 26, and the anti-slip protrusion 12 is composed of a second hard rubber layer 27.

[0032] More specifically, the anti-slip sleeve 10 uses a first hard rubber layer 25 and an air rubber layer 26. The air rubber layer 26 has better fixation with the tire body 3. The anti-slip slider 11 is attached to the groove of the anti-slip sleeve 10. When the anti-slip slider 11 contacts the ground, it is easily compressed, causing the anti-slip protrusion 12 to cooperate with the anti-slip sleeve 10. By utilizing the cooperation of the first hard rubber layer 25 and the second hard rubber layer 27, the friction between the tire body 1 and the ground is increased, improving the anti-slip effect. The first wear-resistant layer 21 is made of artificial rubber or synthetic rubber, which has the excellent properties of high elasticity, aging resistance, and oil resistance of traditional cross-linked vulcanized rubber. The second wear-resistant layer 22 is made of hydrogenated nitrile rubber, which is obtained by special hydrogenation treatment of nitrile rubber. The highly saturated elastomer possesses comprehensive properties such as high temperature resistance, chemical corrosion resistance, high strength, and wear resistance. The third wear-resistant layer 23 adopts a tungsten carbide alloy coating. The wear performance of the tungsten carbide alloy coating is the best among all coatings, regardless of the level or type of wear. Furthermore, with the increase of carbide, its wear resistance is further improved, thus making the tire body 1 more wear-resistant and extending its service life. The high-temperature resistant layer 24 adopts a nano-ceramic coating. The nano-ceramic coating is a high-temperature resistant ceramic coating material formed through a chemical reaction. This coating has excellent high-temperature insulation effect in high-temperature environments, and it can also effectively protect against harsh corrosive environments, thus improving the high-temperature resistance of the tire body 1.

[0033] In summary, during use or operation of the overall equipment: In use, the inner support column 4 is fixedly connected via the fixing pipe 5. Air is injected into the support cavity 13 of the inner support column 4 through the one-way valve 14. The inner support column 4 and the rim 2 are then inserted into the outer tire 3. The seal between the rim 2 and the outer tire 3 utilizes existing technology, such as a sealing strip. Air is pumped into the intake pipe 8, and through the connecting pipe 6 and the outlet pipe 7, air is pumped into the air chamber of the outer tire 3. The intake pipe 8 is then sealed by the valve core. In the event of a puncture or burst in the outer tire 3, the air in the support cavity 13 of the inner support column 4 provides sufficient support, thus facilitating the continued... For continued use, the position of the inner support column 4 between the tire 3 and the rim 2 is limited by the limiting ring 15. A protective layer 9 composed of multiple materials is pasted on the inner surface of the tire 3 so that when the surface of the tire 3 is punctured or damaged by impact, the nylon mesh layer 16 and high-density rubber layer 17 inside the protective layer 9 buffer the impact and tearing force at the moment of impact. Under the pulling action of the nylon mesh layer 16, further damage to the surface of the tire 3 is prevented. Repair is carried out slowly by the adhesive layer 18 to extend the service life of the tire 3. The tire skin layer 19 isolates and prevents air leakage, thus playing a role in explosion prevention and explosion resistance.

[0034] The anti-slip sleeve 10 uses a first hard rubber layer 25 and an air rubber layer 26. The air rubber layer 26 provides better fixation to the tire body 3. The anti-slip slider 11 is attached to the groove of the anti-slip sleeve 10. When the anti-slip slider 11 contacts the ground, it is easily compressed, causing the anti-slip protrusion 12 to cooperate with the anti-slip sleeve 10. The cooperation of the first hard rubber layer 25 and the second hard rubber layer 27 increases the friction between the tire body 1 and the ground, improving the anti-slip effect. The first wear-resistant layer 21 is made of artificial rubber or synthetic rubber, which possesses the excellent properties of high elasticity, aging resistance, and oil resistance of traditional cross-linked vulcanized rubber. The second wear-resistant layer 22 is made of hydrogenated nitrile butadiene rubber, which is a highly saturated material obtained by special hydrogenation treatment of nitrile butadiene rubber. The tire body 1 is made of a tungsten carbide elastomer with comprehensive properties such as high temperature resistance, chemical corrosion resistance, high strength, and wear resistance. The third wear-resistant layer 23 is made of tungsten carbide alloy coating. The wear performance of tungsten carbide alloy coating is the best among coatings, regardless of the layer or type of wear. With the increase of carbide, its wear resistance is further improved, thus making the tire body 1 more wear-resistant and longer in service life. The high temperature resistant layer 24 is made of nano-ceramic coating. Nano-ceramic coating is a high temperature resistant ceramic coating material formed by chemical reaction. This coating has very good high temperature insulation effect in high temperature environment. This coating can also effectively protect against harsh corrosive environments, thus making the tire body 1 more heat resistant.
