Description

A type of tire with high sealing performance Technical Field

[0001] This utility model belongs to the field of tire sealing technology, and in particular relates to a tire with high sealing performance. Background Technology

[0002] As a key component in contact with the ground, the airtightness of tires directly affects driving safety and tire lifespan. Currently, traditional tires face numerous unresolved issues regarding airtightness. On one hand, the connection between the tire and rim often suffers from poor sealing design, leading to slow gas leakage. Statistics show that approximately 46% of traffic accidents are caused by tire failure, with punctures and blowouts accounting for 70% of all accidents, and abnormal tire pressure due to poor sealing is a significant contributing factor. On the other hand, to improve airtightness, some existing technologies increase the thickness of the semi-finished inner liner. This not only results in a heavier finished tire, increasing vehicle fuel consumption, but also makes the molding process more difficult. Furthermore, the application of pre-curing technology can worsen the adhesion of the inner liner, increasing the risk of tire bulging after molding.

[0003] Therefore, it is essential to invent a tire with high sealing performance. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a tire with high sealing performance, including a tire body, tire tread grooves, an inner rim, an outer lip, an outer magnetic strip, an embedded nut, an outer rim, and bolts. The outer surface of the tire body is provided with tire tread grooves, and the inner rim is provided at the inner lip on the inner side. Several outer magnetic strips are provided in the outer lip integrally provided on the tire body, and an embedded nut is embedded in each outer lip. The outer rim is fixed to the embedded nut of the outer lip by bolts.

[0005] Preferably, the inner edge of the tire body is an inner lip, wherein the inner lip is located inside the outer lip integrally formed on the tire body, and there is space between the inner lip and the outer lip to allow the wheel hub edge to engage.

[0006] Preferably, there are two outer lips, and each outer lip has several arc-shaped outer magnetic strips. The outer magnetic strips are not connected to each other, and the outer magnetic strips in the outer lip can be tightly attached to the outer surface of the wheel hub.

[0007] Preferably, each of the outer lips has a plurality of embedded nuts arranged in a circular array, and the outer ring is fixedly installed on the outside of the outer lip by bolts and embedded nuts.

[0008] Preferably, the outer ring has a disc-shaped structure with a rectangular cross-section and rounded edges, and the surface of the outer ring is provided with wear-resistant patterns.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] This invention utilizes an external magnetic strip embedded within the outer lip of the tire to magnetically adhere it tightly to the outer rim surface, creating a dynamic, adaptive seal that effectively resists air leakage caused by pressure fluctuations. Simultaneously, the outer rim is secured to an embedded nut within the outer lip via bolts, providing additional mechanical tightening force. This "magnetic + mechanical" dual-seal structure significantly enhances the sealing performance at the tire-rim connection, substantially reducing the risk of air leakage and improving tire pressure retention.

[0011] The addition of an outer rim in this invention alters the stress distribution pattern of the tire bead, distributing the load over a larger area of ​​the outer lip and mitigating the localized stress concentration problem that might occur with the magnetic ring in the original design. This not only improves the structural stability of the tire under conditions such as high-speed rotation and impact, but also effectively extends the tire's service life and reduces the risk of tire bead damage and blowouts caused by stress concentration.

[0012] Furthermore, the outer wheel rim of this invention can protect the outer lip and inner magnetic ring from damage when the tire is impacted by a sharp object or subjected to complex road conditions, maintaining the tire's basic sealing performance. Even if the magnetic seal fails due to special circumstances, the bolt connection between the outer wheel rim and the outer lip can still ensure a basic fit between the two, slowing down the rate of air leakage and giving the driver more time for emergency response, greatly improving driving safety.

[0019] As shown in Figures 1 and 2:

[0020] This utility model provides a tire with high sealing performance, including a tire body 1, tire tread grooves 2, inner rim 3, outer lip 4, outer magnetic strips 5, embedded nuts 6, outer rim 7, and bolts 8. The tire body 1 has tire tread grooves 2 on its outer surface, and an inner rim 3 is provided at the inner lip on its inner side. Several outer magnetic strips 5 are provided in the outer lip 4 integrally provided on the tire body 1. An embedded nut 6 is embedded in each outer lip 4. The outer rim 7 is fixed to the embedded nut 6 of the outer lip 4 by bolts 8.

[0021] Furthermore, the tire body 1 is made of rubber material, with an inner lip 2 formed at its inner edge. The inner lip 2 and the outer lip 4 are designed as an integral structure on the tire body 1, meaning that the inner lip 2 and the outer lip 4 are a single unit with the tire body 1, formed through a rubber vulcanization process. The inner lip 2 is located inside the outer lip 4, forming a specific space between them. The size of this space is adapted to the size of the wheel hub edge, allowing the wheel hub edge to be smoothly inserted into it, providing a certain positioning and initial sealing effect for the wheel hub edge, laying the foundation for the subsequent adsorption of the outer magnetic strip 5 and the installation of the outer rim 7.

[0022] Furthermore, two outer lips 4 are symmetrically distributed on the outer side of the tire body 1 near the rim. These lips are integrated with the tire body 1 through a rubber vulcanization process. Each outer lip 4 contains several outer magnetic strips 5, which are arc-shaped and their curvature matches the curvature of the rim's outer surface for better contact. The outer magnetic strips 5 are not connected to each other; this design allows each strip to independently adjust to the shape of the rim's outer surface, further improving the fit. The outer magnetic strips 5 are made of neodymium iron boron permanent magnet material, possessing strong magnetism.

[0023] Furthermore, within each outer lip 4, several embedded nuts 6 are evenly distributed in a circular array. During tire vulcanization, the embedded nuts 6 are precisely embedded within the rubber material of the outer lip 4, ensuring accurate positioning and a secure bond with the outer lip 4. The outer rim 7 is a high-strength component, which can be made of materials such as 7075 aluminum alloy or carbon fiber reinforced polymer to ensure sufficient strength and a relatively light weight. The outer rim 7 is connected and fixed to the embedded nuts 6 by bolts 8 and anti-loosening measures (such as anti-loosening washers).

[0024] Furthermore, the outer rim 7 has an overall disc-shaped structure with a rectangular cross-section. This rectangular cross-section design provides the outer rim 7 with strong structural strength, making it less prone to deformation under external forces, thus better reinforcing the outer lip 4. The edges of the outer rim 7 are rounded. This rounded corner design prevents the outer rim 7 from scratching other components during installation and use, while also reducing stress concentration at its edges and improving the durability of the outer rim 7. In addition, the surface of the outer rim 7 is decorated with wear-resistant patterns. These wear-resistant patterns can take various shapes, such as stripes or blocks, and are evenly distributed on its surface. The wear-resistant patterns increase the friction of the outer rim 7 surface. On the one hand, this reduces wear on the surface of the outer rim 7 when the tire comes into contact with external objects, extending its service life; on the other hand, it also improves the interaction between the tire and the ground to a certain extent during vehicle operation, enhancing the vehicle's driving stability.

[0025] The working principle is as follows: First, when installing the tire, the edge of the wheel hub will be engaged in the space between the inner lip 2 and the outer lip 4 on the inner edge of the tire body 1. The inner lip 2 and the outer lip 4 are integrated with the tire body 1 through a rubber vulcanization process. The inner rim 3 is located at the inner lip, which enhances the structural strength of the inner lip 2, ensures the stability of the wheel hub edge engagement, and plays a preliminary positioning and sealing role.

[0026] Secondly, within the two outer lips 4 integrally set on the tire body 1, there are several arc-shaped outer magnetic strips 5. The outer magnetic strips 5 are made of neodymium iron boron permanent magnet material, which has strong magnetism. Its curvature matches the surface of the outer ring of the wheel hub, and it can be tightly adsorbed on the surface of the outer ring of the wheel hub to form a magnetic seal, effectively preventing gas from leaking from the connection between the tire and the wheel hub.

[0027] Next, the embedded nuts 6, arranged in a circular array within each outer lip 4, are embedded in the rubber material of the outer lip 4 during the tire vulcanization process. The outer rim 7 is fixedly connected to the embedded nuts 6 by bolts 8, thus installing the outer rim 7 on the outside of the outer lip 4. The outer rim 7 is made of high-strength 7075 aluminum alloy or carbon fiber reinforced polymer, etc. Its rectangular cross-section structure provides strong structural strength, the rounded corners reduce stress concentration, and the wear-resistant pattern on the surface increases friction, improving the durability and stability of the outer rim 7. At the same time, the bolts 8 provide mechanical reinforcement to the outer lip 4, forming a dual sealing structure of "magnetic force + mechanical force".

[0028] During vehicle operation, when the tire is affected by air pressure fluctuations, centrifugal force, or vibration, the magnetic adsorption of the outer magnetic strip 5 can dynamically and adaptively adjust the sealing force to resist air pressure fluctuations. Meanwhile, the mechanical preload provided by the outer wheel rim 7 through the bolt 8 connection can suppress the axial displacement of the outer lip 4 and prevent loosening caused by vibration. The two work together to maintain the sealing performance of the tire.

[0029] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
