Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a high-strength wear-resistant inner tube structure. Background Technology

[0002] As an important component of tires, the performance of the inner tube directly affects the tire's lifespan and safety.

[0003] Currently, most inner tubes are made of ordinary rubber materials. During long-term use, they are prone to wear, cracking, and air leakage due to friction and compression from the road surface and the effect of internal air pressure.

[0004] Especially in some harsh road conditions, such as rugged mountain roads and gravel roads, the wear and tear on inner tubes is more severe. Not only do they need to be replaced frequently, increasing the cost of use, but they may also cause traffic accidents due to sudden damage to the inner tube, posing a significant safety hazard. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength, wear-resistant inner tube structure, which solves the problem that existing inner tubes suffer severe wear and tear under some harsh road conditions, increasing usage costs and making them prone to safety accidents.

[0006] To achieve the above objectives, this utility model provides a high-strength wear-resistant inner tube structure, including an inner tube body, a buffer layer, a wear-resistant layer, and a reinforcing layer. The buffer layer is connected to the inner tube body and is located on the outside of the inner tube body. The wear-resistant layer is connected to the buffer layer and is located on the side of the buffer layer away from the inner tube body. The reinforcing layer is connected to the inner tube body and is located inside the inner tube body.

[0007] The wear-resistant layer has friction protrusions, which are disposed on one side of the wear-resistant layer and located on the side of the wear-resistant layer away from the buffer layer.

[0008] The high-strength wear-resistant inner tube structure also includes a valve stem, which is connected to and communicates with the inner tube body; the inner tube body has an annular protrusion, which is sleeved on the valve stem.

[0009] The high-strength wear-resistant inner tube structure also includes an edge reinforcement layer, which is connected to the inner tube body and the buffer layer respectively, and the edge reinforcement layer is located between the inner tube body and the buffer layer.

[0010] The high-strength wear-resistant inner tube structure also includes an anti-aging isolation layer, which is connected to the reinforcing layer and located inside the reinforcing layer.

[0011] This utility model discloses a high-strength, wear-resistant inner tube structure. The wear-resistant layer effectively resists the frictional force transmitted from the outer tire, reducing additional wear between the inner tube body and the inner wall of the outer tire caused by road bumps. The buffer layer absorbs the strong impact from the rough road surface transmitted by the outer tire, reducing damage to the inner tube caused by repeated stress. The reinforcing layer enhances the rupture resistance of the inner tube body, significantly reducing the wear rate of the inner tube under harsh road conditions. This effectively reduces the probability of inner tube wear, rupture, and air leakage, lowers the safety hazards caused by sudden inner tube damage, provides more reliable protection for vehicle operation, and improves overall safety.

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] Please see Figures 1 to 3 ,in Figure 1 This is a schematic diagram of the overall structure of a high-strength, wear-resistant inner tube. Figure 2 yes Figure 1 Enlarged view of point A, Figure 3 This is a schematic diagram of the installation structure of the reinforcement layer.

[0019] This utility model provides a high-strength wear-resistant inner tube structure, including an inner tube body 101, a buffer layer 102, a wear-resistant layer 103, a reinforcing layer 104, a valve stem 106, an edge reinforcement layer 108, and an anti-aging isolation layer 109. The wear-resistant layer 103 has friction protrusions 105, and the inner tube body 101 has annular protrusions 107. The wear-resistant layer 103 reduces the wear on the inner tube body 101, the buffer layer 102 absorbs the impact on the inner tube body 101, and the reinforcing layer 104 further enhances the strength of the inner tube body 101 and prevents the inner tube body 101 from breaking. It is understood that the above solution can be used to improve the wear resistance of the inner tube.

[0020] In this specific embodiment, the buffer layer 102 is connected to the inner tube body 101 and located on the outside of the inner tube body 101; the wear-resistant layer 103 is connected to the buffer layer 102 and located on the side of the buffer layer 102 away from the inner tube body 101; the reinforcing layer 104 is connected to the inner tube body 101 and located inside the inner tube body 101; the inner tube body 101 is made of butyl rubber material, which has excellent airtightness and heat resistance, providing a basic guarantee for the performance of the inner tube, and its thickness... The thickness can be adjusted according to the needs of different vehicle models; the reinforcing layer 104 is woven from high-strength aramid fiber, which has excellent properties such as high strength, high modulus and high temperature resistance, and can greatly enhance the overall strength of the inner tube. The thickness of the reinforcing layer 104 is 0.5-1mm, and it is tightly connected to the inner tube body 101 by adhesive; the buffer layer 102 is made of EVA (ethylene-vinyl acetate copolymer) foam material, which has good buffering and energy absorption characteristics, and can effectively reduce the damage of road impact to the inner tube and extend the service life of the inner tube. The buffer layer 102 has a thickness of 0.8-1.2 mm and is firmly bonded to the inner tube body 101 and the wear-resistant layer 103 respectively using an adhesive. The wear-resistant layer 103 is made of polyurethane rubber material. Polyurethane rubber has excellent wear resistance, oil resistance, and aging resistance, which can effectively improve the wear resistance of the inner tube body 101. Its thickness is 1-1.5 mm, and it is connected to the buffer layer 102 by an adhesive. The wear-resistant layer 103 can effectively resist the frictional force transmitted from the outer tire and reduce the wear of the inner tube body 101. The inner tube body 101 experiences additional wear due to road bumps between itself and the inner wall of the outer tire; the buffer layer 102 absorbs the strong impact from the rough road surface transmitted by the outer tire, reducing the damage to the inner tube caused by repeated stress; the reinforcing layer 104 enhances the rupture resistance of the inner tube body 101, significantly reducing the wear rate of the inner tube under harsh road conditions, effectively reducing the probability of inner tube wear, rupture, and air leakage, reducing safety hazards caused by sudden inner tube damage, providing more reliable protection for vehicle driving, and improving overall safety.

[0021] The friction protrusions 105 are disposed on one side of the wear-resistant layer 103 and located on the side of the wear-resistant layer 103 away from the buffer layer 102. Multiple friction protrusions 105 are provided and evenly distributed on the surface of the wear-resistant layer 103. Each friction protrusion 105 can be strip-shaped. The friction protrusions 105 and the wear-resistant layer 103 are manufactured using an integrated molding process, and the material is also polyurethane rubber, ensuring good connection strength and consistency with the wear-resistant layer 103. The friction protrusions 105 further enhance the friction between the inner tube body 101 and the outer tire. When the vehicle is in motion, especially during turning, rapid acceleration, or sudden braking, they effectively prevent relative slippage between the inner tube body 101 and the outer tire, ensuring synchronous movement of the inner tube body 101 and the outer tire, thereby reducing additional wear caused by relative slippage.

[0022] Secondly, the valve stem 106 is connected to and communicates with the inner tube body 101; the inner tube body 101 has an annular protrusion 107, which is sleeved on the valve stem 106; the valve stem 106 is used to inflate the inner tube body 101, and the annular protrusion 107 surrounds the root of the valve stem 106 and is integrally formed with the inner tube body 101. The annular protrusion 107 enhances the firmness of the connection between the valve stem 106 and the inner tube body 101, and prevents air leakage in this part.

[0023] Meanwhile, the edge reinforcement layer 108 is connected to the inner tube body 101 and the buffer layer 102 respectively, and the edge reinforcement layer 108 is located between the inner tube body 101 and the buffer layer 102. The edge reinforcement layer 108 is woven from high-strength nylon fibers and is connected to the inner tube body 101 through a hot vulcanization process. When the vehicle is in motion, the edge of the inner tube body 101 is subjected to continuous compression and friction from the outer tire bead. Especially during tire rolling, the stress situation at the edge is more complex and stress concentration is likely to occur. The edge reinforcement layer 108 can disperse these stresses, enhance the structural stability of the edge of the inner tube body 101, effectively resist the tearing force generated by compression and friction, and prevent damage to the edge of the inner tube body 101. At the same time, the connection between the edge reinforcement layer 108 and the inner tube body 101 and the buffer layer 102 is smoothly transitioned, avoiding excessive local stress caused by abrupt connection, and further improving the overall reliability of the inner tube body 101.

[0024] In addition, the anti-aging isolation layer 109 is connected to the reinforcing layer 104 and located inside the reinforcing layer 104. The anti-aging isolation layer 109 is made of polyimide film material with a thickness of 0.05-0.1mm and is tightly bonded to the reinforcing layer 104 with a high-temperature resistant adhesive. When the vehicle is in motion, ozone will be generated inside the inner tube due to factors such as temperature changes and air pressure fluctuations. This will cause the inner tube body 101 and the reinforcing layer 104 to gradually age and deteriorate, affecting their strength and sealing performance. By setting the anti-aging isolation layer 109, the reinforcing layer 104 is isolated from aging factors, the aging rate of the reinforcing layer 104 and the inner tube body 101 is slowed down, and the service life of the inner tube body 101 is further improved.

[0025] The high-strength wear-resistant inner tube structure of this utility model, with the wear-resistant layer 103 and the friction protrusions 105 working together, significantly reduces the relative wear between the inner tube body 101 and the outer tire; the buffer layer 102 effectively absorbs road impacts and reduces fatigue damage to the inner tube body 101 caused by repeated stress; the reinforcing layer 104 and the edge reinforcement layer 108 further enhance the structural strength of the inner tube body 101, significantly improving its resistance to breakage; the anti-aging isolation layer 109 provides protection for the long-term use of the inner tube, slowing down the aging rate of the material. Compared with existing ordinary rubber inner tubes, the high-strength wear-resistant inner tube structure of this utility model significantly reduces the frequency and cost of inner tube replacement for users, and more importantly, provides protection for vehicle driving safety by reducing the probability of sudden inner tube damage.
