Description

Technical Field

[0001] The utility model relates to the technical field of tires, and specifically relates to a tire with puncture-proof and explosion-proof performance. Background Technique

[0002] For a car in motion, its tire losing most of the air in a very short time is called a flat tire. A flat tire is a common accident form on highways. Traffic accidents caused by flat tires are extremely harmful. Especially when the vehicle is driving at high speed, it is extremely easy to get out of control, resulting in vehicle damage and death, seriously threatening the lives of drivers and passengers.

[0003] At present, in order to improve the explosion-proof effect of tires, solid tires are mostly used. A solid tire is an industrial tire suitable for use under low-speed and high-load conditions. Its safety, durability, etc. are significantly better than pneumatic tires. It is widely used in various industrial vehicles, military vehicles, construction machinery, trailer vehicles at ports and airports, etc. However, the solid tire has a poor adaptability to the road surface, a weak shock-absorbing ability, and a bumpy ride. At the same time, due to its weight, it is only suitable for low-speed driving and cannot be widely applied to cars. Therefore, a tire with puncture-proof and explosion-proof performance is proposed to solve the above problems. Content of the Utility Model

[0004] In view of the deficiencies of the prior art, the utility model provides a tire with puncture-proof and explosion-proof performance, which has the advantages of improving practicability and puncture-proof and explosion-proof performance, and solves the problem of poor puncture-proof and explosion-proof performance.

[0005] To achieve the above object, the utility model provides the following technical solution: A tire with puncture-proof and explosion-proof performance, including a wheel hub and a tire body sleeved outside the wheel hub;

[0006] The tire body is composed of a rigid support layer, an elastic support layer, an elastic buffer layer, a tire body meridian layer, a rubber surface layer, a first protective layer, a second protective layer, and a third protective layer. The elastic support layer is fixedly connected to the outside of the rigid support layer. The elastic buffer layer is fixedly connected between the elastic support layer and the rigid support layer. The tire body meridian layer is fixedly connected to the outside of the elastic buffer layer. The first protective layer is fixedly connected to the outside of the elastic support layer. The second protective layer is fixedly connected to the outside of the first protective layer. The third protective layer is fixedly connected to the outside of the second protective layer. The rubber surface layer is fixedly connected to the outside of the third protective layer.

[0007] Further, the rigid support layer is made of a mixture of a lightweight porous rigid material and carbon nanotubes, and the elastic support layer is styrene-butadiene rubber.

[0008] Further, the elastic buffer layer is semicircularly distributed between the rigid support layer and the elastic support layer, and the elastic buffer layer is a lightweight porous elastic material layer.

[0009] Furthermore, the first protective layer, the second protective layer, and the third protective layer are arc-shaped and distributed between the rubber surface layer and the elastic support layer, and the first protective layer is a thin steel strip layer.

[0010] Furthermore, the second protective layer is a nylon belt layer, and the third protective layer is a thick steel strip layer.

[0011] Furthermore, the rubber surface layer is made of a mixture of cis-butadiene rubber and natural rubber, and anti-slip patterns are provided on the outer side of the rubber surface layer.

[0012] Furthermore, the elastic support layer is U-shaped and distributed between the carcass meridian layer and the rigid support layer.

[0013] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0014] 1. For the puncture-proof and explosion-proof tire, since the entire carcass is filled with a rigid support layer, and since the rigid support layer is made of a mixture of a lightweight porous rigid material and carbon nanotubes, and the elastic buffer layer is a lightweight porous elastic material layer, when the entire tire is solid, the weight of the entire tire is reduced to improve the explosion-proof performance of the entire tire. At the same time, since the elastic support layer is styrene-butadiene rubber, the buffering performance during the formation of the entire tire can be improved, thereby improving the comfort.

[0015] 2. For the puncture-proof and explosion-proof tire, since the first protective layer, the second protective layer, and the third protective layer are sequentially arranged between the elastic support layer and the rubber surface layer, the rigidity of the ground contact end of the entire tire is improved, thereby improving the puncture-proof effect.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 to 2 , a tire with puncture-proof and explosion-proof performance in this embodiment includes a wheel hub 2 and a tire body 1 sleeved outside the wheel hub 2;

[0023] The tire body 1 is composed of a rigid support layer 11, an elastic support layer 12, an elastic buffer layer 13, a tire body meridian layer 14, a rubber surface layer 15, a first protective layer 16, a second protective layer 17 and a third protective layer 18. The elastic support layer 12 is fixedly connected to the outside of the rigid support layer 11. The rigid support layer 11 is made of a mixture of a lightweight porous rigid material and carbon nanotubes. Due to the unique structure of carbon nanotubes, it has ultra-high strength, great toughness, unique electrical conductivity and thermal conductivity and other excellent properties. As a reinforcing agent, it can greatly improve the mechanical properties of the composite material. It can provide excellent reinforcement performance for the rubber matrix and improve its fatigue resistance. Moreover, its thermal conductivity, tear resistance and wear resistance are excellent. While ensuring the rigidity of the tire itself, it can also greatly reduce its own weight;

[0024] The elastic support layer 12 is styrene-butadiene rubber, which can be used in combination with resins and rubbers for modification. As a filler, it can adjust stiffness, hardness, softness, knotting property and flexural resistance;

[0025] The elastic buffer layer 13 is fixedly connected between the elastic support layer 12 and the rigid support layer 11. The elastic buffer layer 13 is semicircularly distributed between the rigid support layer 11 and the elastic support layer 12. The elastic buffer layer 13 is a lightweight porous elastic material layer. While improving the buffer performance of the tire in cooperation with the elastic support layer 12, it can further reduce the weight of the tire. The tire body meridian layer 14 is fixedly connected to the outside of the elastic buffer layer 13.

[0026] In this embodiment, since the entire tire body 1 is filled with the rigid support layer 11, and the rigid support layer 11 is made of a mixture of a lightweight porous rigid material and carbon nanotubes, and the elastic buffer layer 13 is a lightweight porous elastic material layer, when the entire tire is solid, the weight of the entire tire is reduced to improve the explosion-proof performance of the entire tire. At the same time, since the elastic support layer 12 is styrene-butadiene rubber, it can improve the buffering performance during the formation of the entire tire, thereby improving the comfort.

[0027] Please refer to Figures 2 to 4, in this embodiment, the first protective layer 16 is fixedly connected to the outside of the elastic support layer 12, the second protective layer 17 is fixedly connected to the outside of the first protective layer 16, the third protective layer 18 is fixedly connected to the outside of the second protective layer 17, and the rubber surface layer 15 is fixedly connected to the outside of the third protective layer 18;

[0028] The first protective layer 16, the second protective layer 17, and the third protective layer 18 are arc-shaped and distributed between the rubber surface layer 15 and the elastic support layer 12. The first protective layer 16 is a thin steel strip layer, the second protective layer 17 is a nylon belt layer, and the third protective layer 18 is a thick steel strip layer. The rubber surface layer 15 is made of a mixture of cis-butadiene rubber and natural rubber. Anti-slip patterns are provided on the outside of the rubber surface layer 15. Through the first protective layer 16, the second protective layer 17, and the third protective layer 18, the rigidity of the entire tire's ground contact end is increased, thereby reducing the possibility of foreign objects piercing the tire.

[0029] Among them, the elastic support layer 12 is U-shaped and distributed between the carcass meridian layer 14 and the rigid support layer 11.

[0030] In this embodiment, since the first protective layer 16, the second protective layer 17, and the third protective layer 18 are sequentially arranged between the elastic support layer 12 and the rubber surface layer 15, the rigidity of the entire tire's ground contact end is increased, thereby improving the puncture resistance effect.

[0031] The working principle of the above embodiment is as follows:

[0032] Since the entire carcass 1 is filled with the rigid support layer 11, and since the rigid support layer 11 is made of a mixture of a lightweight porous rigid material and carbon nanotubes, and the elastic buffer layer 13 is a lightweight porous elastic material layer, when the entire tire is solid, the weight of the entire tire is reduced to improve the explosion-proof performance of the entire tire. At the same time, since the elastic support layer 12 is styrene-butadiene rubber, the buffering performance during the formation of the entire tire can be improved, thereby improving the comfort. And since the first protective layer 16, the second protective layer 17, and the third protective layer 18 are sequentially arranged between the elastic support layer 12 and the rubber surface layer 15, the rigidity of the entire tire's ground contact end is increased, thereby improving the puncture resistance effect.
