Description

Technical Field

[0001] The utility model relates to the field of tires, in particular to a hollow tire with an air valve. Background Art

[0002] Tires are ground-connected, rolling, elastic rubber products installed on various vehicles and machinery. They bear weight, cushion road impacts, maintain contact with the road, and provide driving and braking forces. Tires are subject to various deformations, loads, forces, and high and low temperature conditions during driving, so they must possess high load-bearing, traction, and cushioning properties.

[0003] Since Dunlop invented the pneumatic tire over 100 years ago, tire technology has continued to evolve. Traditional pneumatic tires, supported by high-pressure air, offer excellent comfort and cushioning, making them suitable for high-speed driving. However, they suffer from drawbacks such as susceptibility to punctures and slow air leakage, requiring prompt inflation.

[0004] In recent years, with the development of slow, short-distance vehicles such as electric bicycles and scooters, especially shared electric vehicles and shared bicycles, due to the poor operating environment, in order to avoid puncture and leakage, some use non-pneumatic tires such as solid tires and hollow tires. Because these tires have no air support, the various deformations and loads they endure during driving are all borne by the tire carcass material, which can easily cause tire damage. Increasing the load-bearing capacity requires a stronger and harder tire carcass, which in turn reduces tire comfort and makes the tire heavier, resulting in greater energy loss during use. In the case of shared electric vehicles, this increases maintenance costs. Therefore, improvements to the tire structure are needed. Utility Model Content

[0005] The purpose of this utility model is to design a hollow tire with a valve nozzle in order to solve the above problems. By filling the hollow tire with high-pressure air, the load-bearing capacity is improved, the hardness and strength of the hollow tire body can be reduced, and the comfort and tire service life are improved.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] The utility model provides a hollow tire with an air valve, which comprises a tire body and an air valve. The air valve is built into the tire body.

[0008] As a preferred embodiment of the present invention, the carcass shape can be various cross-sectional shapes according to needs, with an inner hole in the cross-sectional shape. The carcass can be an outer tire with a pattern for direct contact with the road surface or an inner tire without a pattern.

[0009] As a preference of the present invention, the number of inner holes can be one, two or more.

[0010] As a preferred embodiment of the present invention, in order to ensure airtightness and puncture resistance, the outer wall thickness is not less than 5 mm.

[0011] As a preferred embodiment of the present invention, the valve is a rubber cushion valve, including a valve cushion, a valve body, and a valve core. The valve cushion and the hollow tire body are bonded together through a rubber vulcanization process to ensure airtightness. The valve body is hidden in the hollow tire body and can be positioned at any position on the cross-section of the hollow tire body.

[0012] The beneficial effects of this utility model are as follows: Compared with ordinary hollow tires, this patented hollow tire is equipped with a valve, which can be filled with high-pressure gas, thereby enhancing load-bearing capacity and cushioning performance, and extending tire life. At the same time, the thickness of the tire body material ensures airtightness and puncture resistance, preventing puncture and leakage during use, achieving the purpose of a maintenance-free hollow tire. In addition, because the valve is built-in, the appearance of the hollow tire is the same as that of an ordinary hollow tire, which does not affect assembly. BRIEF DESCRIPTION OF THE DRAWINGS
