Description

Technical Field

[0001] This utility model relates to the field of special tires for utility vehicles, and in particular to a high-temperature resistant and flame-retardant special tire for utility vehicles. Background Technology

[0002] In specialized fields such as industrial production, fire rescue, and military operations, utility vehicles frequently need to perform transportation tasks in high-temperature, open-flame, and harsh environments. Traditional rubber tires soften and deform at temperatures exceeding 200°C and rapidly degrade and fail above 300°C, severely limiting the operational capabilities of these vehicles in high-temperature environments such as metallurgical workshops and fire scenes. However, existing utility vehicle tires still suffer from poor high-temperature resistance, lack of flame retardancy, and inability to provide comprehensive tire protection.

[0003] Therefore, it is essential to invent a special tire for utility vehicles that is resistant to high temperatures and flames. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a high-temperature resistant and flame-retardant special tire for utility vehicles, solving the issues that existing special tires for utility vehicles still suffer from poor high-temperature resistance, lack of flame-retardant capabilities, and inability to provide comprehensive tire protection. A high-temperature resistant and flame-retardant special tire for utility vehicles includes tire spokes, a tire rim, a tire body, a protective outer layer, and protective sideplates. The tire rim is fixedly mounted on the periphery of the tire spokes, and the tire body is mounted on the periphery of the tire rim. The protective outer layer is fixedly mounted on the periphery of the tire body. The protective sideplates are fixedly mounted on the outer side of the tire spokes.

[0005] The protective outer layer includes a connecting base, a heat-insulating raised pattern, a contact surface, and heat-insulating and anti-slip protrusions. The connecting base is fixedly installed on the periphery of the tire body, and the heat-insulating raised pattern is fixedly installed on the outer surface of the connecting base. The contact surface is fixedly installed on the surface of the heat-insulating raised pattern, and the heat-insulating and anti-slip protrusions are fixedly installed on the surface of the contact surface.

[0006] The protective side plate includes a mounting base plate, a support wall, a connecting ring, a docking ring, and a dustproof net. The support wall is fixedly mounted on the surface of the mounting base plate, which is fixedly mounted on the outer side of the tire spokes. The connecting ring is fixedly mounted on the inner wall of the support wall, and the docking ring is fixedly mounted on the surface of the connecting ring. The dustproof net is fixedly mounted inside the docking ring.

[0007] The heat-insulating raised pattern inside the protective outer layer uses several sets of "W"-shaped protrusions, and the connecting base uses a silicone rubber annular flame-retardant strip with an arc-shaped cross-section. The connecting base is infused with aluminum hydroxide flame retardant. The connecting base is integrated with the tire body. The heat-insulating raised pattern is made of polyimide rubber blocks, and the thickness of the heat-insulating raised pattern is 4 to 5 cm. The contact surface and the heat-insulating and anti-slip protrusions are integrally molded and both are made of silicone rubber. The heat-insulating and anti-slip protrusions use several circular protrusions with uneven diameters. Through the connecting base, they provide high-temperature stability and flame retardant performance. The heat-insulating raised pattern reduces heat conduction and enhances heat dissipation. The contact surface and the heat-insulating and anti-slip protrusions optimize grip and anti-slip performance. At the same time, the "W"-shaped pattern design and the 4 to 5 cm thickness form a heat-insulating buffer layer, ensuring that the tire still has excellent heat resistance, flame retardancy, and driving safety in high-temperature, high-friction, and harsh environments.

[0008] The mounting base plate, support wall, and connecting ring inside the protective side plate completely enclose the tire spokes and tire hub. The mounting base plate, support wall, and connecting ring are all made of polyimide sheet. The dustproof net is a set of circular flame-retardant magnesium alloy mesh, which seals the voids formed by the support wall. Through the mounting base plate, support wall, and connecting ring, a high-temperature resistant sealing structure is formed, completely enclosing the tire spokes and tire hub to prevent external high temperatures and foreign objects from intruding. The connecting ring and dustproof net work together to effectively block dust and particulate matter while ensuring ventilation and heat dissipation, ensuring the hub area is clean and reducing the impact of heat radiation, thereby improving the overall protective performance and operational stability of the tire in extreme environments.

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

[0010] 1. The protective outer layer of this utility model provides high-temperature stability and flame retardant performance by connecting to the substrate. The heat-insulating raised pattern reduces heat conduction and enhances heat dissipation. The ground contact and heat-insulating anti-slip raised points optimize grip and anti-slip performance. At the same time, the "W" shaped pattern design and 4 to 5 cm thickness form a heat-insulating buffer layer, ensuring that the tire still has excellent heat resistance, flame retardancy and driving safety in high temperature, high friction and harsh environments.

[0011] 2. The protective side plate of this utility model forms a high-temperature resistant sealing structure by installing a base plate, supporting wall and connecting ring, which completely wraps the tire spokes and tire hub to prevent external high temperature and foreign objects from intruding; the docking ring and dustproof net work together to effectively block dust and particulate matter while ensuring ventilation and heat dissipation, ensuring the hub area is clean and reducing the impact of heat radiation, thereby improving the overall protective performance and operational stability of the tire in extreme environments.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] As attached Figure 1 To be continued Figure 4 As shown.

[0020] This utility model provides a high-temperature resistant and flame-retardant special tire for utility vehicles, comprising a tire spoke 1, a tire hub 2, a tire body 3, a protective outer layer 4, and a protective side plate 5, wherein: the tire hub 2 is fixedly installed on the periphery of the tire spoke 1, and the tire body 3 is installed on the periphery of the tire hub 2, and the protective outer layer 4 is fixedly installed on the periphery of the tire body 3; the protective side plate 5 is fixedly installed on the outer side of the tire spoke 1.

[0021] The protective outer layer 4 includes a connecting base 41, a heat-insulating raised pattern 42, a contact surface 43, and heat-insulating and anti-slip protrusions 44. The connecting base 41 is fixedly installed on the periphery of the tire body 3, and the heat-insulating raised pattern 42 is fixedly installed on the outer surface of the connecting base 41. The contact surface 43 is fixedly installed on the surface of the heat-insulating raised pattern 42, and the heat-insulating and anti-slip protrusions 44 are fixedly installed on the surface of the contact surface 43.

[0022] The protective side plate 5 includes a mounting base plate 51, a support wall 52, a connecting ring 53, a docking ring 54, and a dustproof net 55. The support wall 52 is fixedly mounted on the surface of the mounting base plate 51, which is fixedly mounted on the outer side of the tire spoke 1. The connecting ring 53 is fixedly mounted on the inner wall of the support wall 52, and the docking ring 54 is fixedly mounted on the surface of the connecting ring 53. The dustproof net 55 is fixedly mounted inside the docking ring 54.

[0023] The heat-insulating raised pattern 42 inside the protective outer layer 4 uses several sets of "W"-shaped protrusions, and the connecting base 41 uses a silicone rubber annular flame-retardant strip with an arc-shaped cross section. The connecting base 41 is mixed with aluminum hydroxide flame retardant. The connecting base 41 is integrated with the tire body 3. The heat-insulating raised pattern 42 is made of polyimide rubber block, and the thickness of the heat-insulating raised pattern 42 is 4 to 5 cm. The contact surface 43 and the heat-insulating anti-slip protrusions 44 are integrally formed and are both made of silicone rubber. The heat-insulating anti-slip protrusions 44 use several circular protrusions with uneven diameters.

[0024] The mounting base plate 51, support wall 52 and connecting ring 53 inside the protective side plate 5 completely wrap the tire spokes 1 and tire hub 2 inside it, and the mounting base plate 51, support wall 52 and connecting ring 53 are all made of polyimide sheet; the dustproof net 55 is a set of circular flame-retardant magnesium alloy mesh, and the dustproof net 55 can seal the holes formed by the support wall 52.

[0025] This special tire uses tire spokes 1 and tire rim 2 to form the main support frame, the tire body 3 to provide cushioning, and the protective outer layer 4 and protective side plates 5 to form a dual thermal protection system. The protective outer layer 4 is made of flame-retardant silicone rubber and high-temperature resistant polyimide rubber, combined with a "W"-shaped heat dissipation structure and a thickness of 4-5cm, to effectively block high ground temperatures; the protective side plates 5 use polyimide sheets and magnesium alloy dustproof mesh 55 to block lateral heat radiation, achieving three-dimensional thermal management.

[0026] During operation, the heat-insulating and anti-slip protrusions 44 optimize grip, while the dustproof mesh 55 balances heat dissipation and dust prevention needs. All components work synergistically: when exposed to high temperatures, the flame-retardant material slows combustion, and the raised tread pattern promotes air convection for heat dissipation; in open flame environments, the multi-layered protective structure can maintain its integrity for more than 30 minutes. This dual innovation in materials and structure ensures the stability and safety of the vehicle even under extreme conditions such as 800℃, making it particularly suitable for high-temperature and high-risk scenarios such as metallurgy and firefighting.

[0027] 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.
