Description

Technical Field

[0001] This utility model relates to the field of motorcycle parts technology, specifically to an explosion-proof reinforced motorcycle inner tube. Background Technology

[0002] As the core component of pneumatic tires, motorcycle inner tubes maintain tire shape and absorb road impacts through internal air pressure. Their traditional design mainly relies on a single-layer rubber structure to achieve sealing and cushioning functions, but this is limited by material strength and structural simplicity.

[0003] When traditional inner tubes encounter high pressure, high-speed friction, or puncture by sharp objects, the cord layer is prone to breakage due to stress concentration. The airtight rubber layer is unable to effectively seal the crack propagation path, leading to rapid gas leakage or even instantaneous tire blowout. At the same time, the lack of a puncture-proof layer or insufficient thickness prevents the inner tube from dispersing the energy of sudden impacts. The low coverage of high-density fibers in the puncture-proof layer further weakens the active defense against puncture damage. These problems significantly increase the riding risk and shorten the lifespan of the inner tube. Especially in complex road conditions or extreme load scenarios, the insufficient puncture-proof performance of traditional inner tubes directly restricts the safety and reliability of motorcycles. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide an explosion-proof reinforced motorcycle inner tube to solve the problem of poor explosion-proof performance of traditional motorcycle inner tubes mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an explosion-proof reinforced motorcycle inner tube, comprising an inner tube body, an inner tube valve assembly fixedly disposed on the inner ring of the inner tube body, the inner tube body comprising a cord layer, an airtight rubber layer fixedly disposed on the outer ring of the cord layer, an explosion-proof layer fixedly disposed on the outer layer of the airtight rubber layer, a buffer layer fixedly disposed on the outer layer of the explosion-proof layer, a sidewall rubber layer fixedly disposed on the outer layer of the buffer layer, a puncture-proof layer fixedly disposed on the outer layer of the sidewall rubber layer, and an anti-oxidation coating sprayed on the outer layer of the puncture-proof layer. The cord layer provides structural support through a high-strength fiber woven network, dispersing motion. The tire is designed to withstand stress and prevent uncontrolled deformation, maintaining tire shape stability. The airtight rubber layer tightly adheres to the cord layer to form a sealed barrier, preventing gas leakage and enhancing the even distribution of internal pressure. The puncture-proof layer uses tear-resistant materials to absorb high-pressure impact energy, reducing the risk of sudden tire blowouts. The cushioning layer uses elastic rubber to absorb the energy from road bumps, reducing the amplitude of vibration transmission and improving riding comfort. The sidewall rubber layer uses a weather-resistant formula to resist external friction and chemical corrosion, slowing down the aging of the tire body. The puncture-proof layer uses a high-density fiber mesh to actively intercept sharp objects and inhibit the spread of damage. The anti-oxidation coating slows down the aging process of materials by inhibiting the oxidation reaction of rubber molecules, extending service life.

[0008] Preferably, the outer layer of the antioxidant coating is coated with a wear-resistant coating, and the outer layer of the wear-resistant coating is coated with a talc powder coating. The wear-resistant coating uses high-hardness particles to fill the micropores on the surface to reduce the friction loss rate. The talc powder coating reduces the outer layer resistance during installation by relying on its low friction characteristics, ensuring a smooth fit between the inner tube and the rim.

[0009] Preferably, the valve assembly includes a reinforcing plate, and the reinforcing plate is fixedly disposed inside the inner tube body. The reinforcing plate is rigidly connected to fix the valve area, thereby improving structural stability.

[0010] Preferably, a valve body is fixedly provided at the end of the reinforcing sheet away from the inner tube body. The valve body is connected to the reinforcing sheet through a connecting rod. The connecting rod securely connects the valve body and the reinforcing sheet, maintaining airtightness and preventing the interface from loosening.

[0011] Preferably, a valve core is provided at the end of the valve body away from the inner tube body, and a valve cap is movably provided at the front end of the valve core. The valve core adjusts the gas flow through a precision valve to ensure inflation efficiency and sealing. The valve cap covers the front end of the valve to prevent dust and moisture from entering the valve body and maintain valve cleanliness.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This explosion-proof reinforced motorcycle inner tube has a cord layer that provides core support through a high-strength fiber woven network, effectively dispersing dynamic stress during driving and preventing deformation and loss of control. At the same time, it is tightly combined with the airtight rubber layer to form a double sealing barrier, which not only prevents gas leakage but also uses the tear-resistant properties of the explosion-proof layer to resist high-pressure impact. Furthermore, combined with the high-density fiber mesh of the puncture-proof layer, it can actively intercept sharp objects and slow down the expansion of damage, thus constructing a three-dimensional safety protection system from the inside out.

[0014] 2. This explosion-proof reinforced motorcycle inner tube features a buffer layer that absorbs road bumps through elastic rubber material, reducing the intensity of vibration transmitted inward. Combined with the weather-resistant formula of the sidewall rubber layer, it can simultaneously alleviate the erosion of the tire body by external friction and chemical corrosion. The talc coating reduces the resistance of the outer layer during installation through its low-friction characteristics, ensuring a smoother fit between the inner tube and the rim. This dynamic adaptation design significantly improves riding stability and handling feedback sensitivity.

[0015] 3. This explosion-proof reinforced motorcycle inner tube features an anti-oxidation coating that slows down the aging process by inhibiting the oxidation and breakage of rubber molecular chains, while a wear-resistant coating uses high-hardness particles to fill the surface micropores and reduce the wear rate. The synergistic effect of the two significantly extends the service life of the inner tube. The valve assembly maintains airtight stability through the rigid connection between the reinforcing plate and the valve body. Combined with the dustproof sealing function of the valve cap, tire pressure adjustment and daily maintenance are more convenient and reliable. Attached Figure Description

[0024] The outer layer of the anti-oxidation coating 107 is coated with a wear-resistant coating 108, and the outer layer of the wear-resistant coating 108 is coated with a talc coating 109. The valve assembly 2 includes a reinforcing plate 201. The reinforcing plate 201 is fixedly installed inside the inner tube body 1.

The valve core 204 has a built-in precision valve to regulate the gas flow rate to balance inflation efficiency and sealing. The valve cap 205 covers the front end of the valve core 204 to prevent dust and moisture from entering the interior of the valve body 203 to maintain valve cleanliness.
