Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to a run-flat safety tire. Background Technology

[0002] One of the most common major accidents on highways is tire blowout leading to loss of vehicle control. In many cases, tires become flat and unable to move due to punctures, aging, or leaks. Many drivers lack the experience or equipment to change the tire, causing delays. Therefore, people have been developing run-flat tires, which can effectively prevent loss of vehicle control and ensure continued driving even in the event of a blowout.

[0003] However, existing run-flat safety tires are prone to dents when driven with zero air pressure, which can lead to tire damage. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, this utility model provides a run-flat safety tire, which solves the problem that existing run-flat safety tires are prone to denting when driven with zero air pressure, thus leading to tire damage.

[0006] (II) Technical Solution

[0007] To achieve the above, this utility model provides the following technical solution: a run-flat safety tire, comprising a body and a rim:

[0008] The main body has teeth surrounding its outer surface and a protective layer on its exterior.

[0009] The wheel hub has an internal buffer ring, and a connecting rod surrounds the outer wall of the buffer ring. This effectively achieves wear resistance for the main body and allows the vehicle to run normally even with zero tire pressure, thus providing support for the main body.

[0010] Optionally, the main body is surrounded by support columns. Each support column is composed of a large-diameter sleeve and a small-diameter connecting rod. The support column is equipped with a spring, which can effectively buffer the main body when it moves. At the same time, it can support the main body when it is traveling with zero air pressure, thus preventing the main body from collapsing when there is no air pressure.

[0011] Optionally, the body has an internal wear-resistant layer, which can be made of polyurethane and butadiene rubber materials, effectively achieving wear resistance and preventing the body from cracking.

[0012] Optionally, the body has an anti-tensile layer located below the wear-resistant layer. The anti-tensile layer is composed of two tensile plates, both of which are irregularly L-shaped and have grooves. The two tensile plates interlock to effectively increase the tensile strength of the body and further improve its wear resistance.

[0013] Optionally, a support plate is provided below the wear-resistant layer. The two support plates are arranged in a triangle and are axially symmetrical, which can further support the main body and enable the main body to drive smoothly when there is no air pressure.

[0014] Optionally, the other end of the connecting rod is provided with a top plate. The top of the top plate is semi-circular and contacts the inner wall of the wheel hub, which can effectively support the wheel hub and continuously provide further support to the main body, preventing the main body from collapsing when driving without air pressure.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a run-flat safety tire with the following advantages:

[0017] 1. This utility model, through a protective layer, support columns, and a wear-resistant layer, protects the gear teeth from wear when the main body is running without air pressure. When the main body is running at 0 air pressure, the support columns provide internal support, preventing dents. Simultaneously, when the main body is running at 0 air pressure, the small-diameter connecting rod moves within the large-diameter sleeve. The spring's buffering and rebounding effect provides both cushioning and internal support. The spring's rebound force allows the main body to instantly spring back, restoring any dents. Polyurethane, with a wear resistance of only 30–80 mm³, is 3–5 times that of ordinary rubber. Its high strength and fatigue resistance reduce the risk of cracks and fractures, significantly extending service life. Meanwhile, butadiene rubber has a wear resistance of 80–140 mm³, balancing wear resistance and tear resistance, further enhancing the wear resistance of the main body and preventing it from wearing out.

[0018] 2. This utility model uses a tensile-resistant layer. When the main body is in motion, the two tensile plates pull against each other, which effectively increases the tensile strength of the main body and improves its service life. Furthermore, the mutual pulling of the two tensile plates increases the puncture resistance of the main body, thus achieving a protective effect.

[0019] 3. This utility model, through the support plate and top plate, provides further support to the interior of the main body when driving under zero air pressure. The triangular support plate provides more stable support to the main body, further preventing the main body from sinking when driving under zero air pressure. The top plate supports the interior of the wheel hub, thereby preventing the wheel hub from deforming during driving, and further achieving the support effect for the main body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1 to 5 The present invention provides a technical solution: a run-flat safety tire, comprising a body 1 and a hub 2.

[0028] The main body 1 has teeth 101 surrounding its outer surface and a protective layer 102 on its exterior.

[0029] The wheel hub 2 has a buffer ring 201 inside, and a connecting rod 202 is arranged around the outer wall of the buffer ring 201. When the main body 1 is driving without air pressure, the wheel teeth 101 are protected by the protective layer 102 to prevent wear of the wheel teeth 101. At the same time, the buffer ring 201 inside the wheel hub 2 can effectively achieve the buffering effect of the wheel hub 2. The wheel hub 2 achieves the buffering effect of the main body 1 when buffering, preventing the main body 1 from denting when driving with zero air pressure.

[0030] Based on the above embodiments, in this embodiment, the main body 1 is surrounded by a support column 103. The support column 103 is composed of a large-diameter sleeve and a small-diameter connecting rod. The support column 103 is equipped with a spring. When the main body 1 is traveling at zero air pressure, the support column 103 supports the interior of the main body 1, firstly preventing the main body 1 from denting. At the same time, when the main body 1 is traveling at zero air pressure, the small-diameter connecting rod moves inside the large-diameter sleeve. At this time, through the buffering and rebounding effect of the spring, the buffering effect of the main body 1 can be achieved, and the internal support effect of the main body 1 can be achieved. The main body 1 traveling at zero air pressure can be instantly rebounded by the rebounding force of the spring, so that the dent of the main body 1 is reset.

[0031] Based on the above embodiments, in this embodiment, the main body 1 is provided with a wear-resistant layer 104. The wear-resistant layer 104 can be supported by polyurethane and butadiene rubber materials. When the main body 1 is in motion, the wear amount of polyurethane is only 30-80 mm³, which is 3-5 times that of ordinary rubber. Its high strength and fatigue resistance can reduce the risk of cracking and breakage, and significantly extend the service life. At the same time, the wear amount of butadiene rubber is 80-140 mm³, which can balance wear resistance and tear resistance, thereby further achieving a wear-resistant effect on the main body 1 and preventing the main body 1 from wearing out.

[0032] Based on the above embodiments, in this embodiment, the body 1 has an anti-tensile layer 105 located below the wear-resistant layer 104. The anti-tensile layer 105 is composed of two tension plates, both of which are irregularly L-shaped and have grooves 107. The two tension plates interlock, and when the body 1 is in motion, the two tension plates pull on each other. When they pull on each other, they can effectively increase the tensile strength of the body 1 and improve its service life. Furthermore, the mutual pulling of the two tension plates can increase the puncture resistance of the body 1, thus achieving a protective effect on the body 1.

[0033] Based on the above embodiments, in this embodiment, a support plate 106 is provided below the wear-resistant layer 104. The two support plates 106 are arranged in a triangle and are axially symmetrical. When the main body 1 is traveling under zero air pressure, the two support plates 106 provide further support to the interior of the main body 1. The triangular support plates 106 can more stably support the main body 1, further preventing the denting phenomenon that occurs when the main body 1 is traveling under zero air pressure.

[0034] Based on the above embodiments, in this embodiment, the other end of the connecting rod 202 is provided with a top plate 203. The top of the top plate 203 is semi-circular and contacts the inner wall of the wheel hub 2. When the main body 1 is driving under 0 air pressure, the top plate 203 supports the inside of the wheel hub 2, thereby preventing the wheel hub 2 from deforming during driving and further achieving the support effect for the main body 1.
