Description

Technical Field

[0001] This utility model relates to the field of tires, and in particular to an explosion-proof polyurethane tire for engineering vehicles. Background Technology

[0002] In the field of engineering construction, engineering vehicles play a crucial role, often operating in complex and harsh environments such as mines, construction sites, and deserts. These environments place extremely high demands on tire performance. As the only component of an engineering vehicle in contact with the ground, the performance of the tires directly affects the vehicle's driving safety, work efficiency, and operating costs.

[0003] Construction vehicles operate in complex environments with poor road conditions, often containing sharp stones, metal fragments, and other debris. Traditional tires are easily punctured or cut by these sharp objects, leading to instantaneous loss of tire pressure or even a blowout. A tire blowout not only causes the vehicle to lose control and lead to serious safety accidents, but also interrupts the project, affects the construction schedule, and increases maintenance costs.

[0004] Secondly, engineering vehicles typically carry heavy loads, requiring their tires to withstand immense pressure and impact during operation. Traditional tire designs often struggle to meet these high-intensity demands, leading to tire deformation and cracking after prolonged exposure to heavy loads and impacts. This shortens tire lifespan and increases the frequency and cost of tire replacements. Utility Model Content

[0005] The purpose of this invention is to provide an explosion-proof polyurethane tire for engineering vehicles, which solves the problems of poor explosion-proof performance and insufficient structural strength of existing engineering vehicle tires.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: An explosion-proof polyurethane tire for engineering vehicles includes a hub and a tire body. The tire body covers the outside of the hub, and several metal rings are arranged equidistantly inside the tire body. The metal rings are sleeved on the outside of the hub, and a reinforcing sleeve is provided inside the tire body. The reinforcing sleeve is arranged on the outside of the several metal rings in a spiral winding manner.

[0007] Preferably, the tire body is integrally formed on the outside of the metal ring and reinforcing sleeve by a casting process. The integrally formed structure makes the tire components tightly connected and has good overall integrity.

[0008] Preferably, the outer surface of the tire body is provided with anti-slip treads to enhance the tire's anti-slip performance and improve the grip of engineering vehicles under different road conditions.

[0009] Preferably, a buffer pad is provided between the wheel hub and the metal ring to buffer and reduce shock, thereby reducing the vibration and impact force on the tire and wheel hub during driving.

[0010] Preferably, the outer walls on both sides of the tire carcass are provided with grooves arranged in a ring array. The width of the groove opening gradually increases from the side near the wheel hub towards the outer edge of the tire carcass, forming a gradient groove structure that can better withstand pressure and maintain the structural stability of the tire carcass.

[0011] Preferably, the cross-section of the metal ring is circular, which can uniformly distribute stress, reduce deformation and damage in local areas of the metal ring, improve the stability and reliability of the metal ring, and thus extend the service life of the tire.

[0012] Preferably, the depth of the groove gradually decreases from the outer periphery of the tire to the inner periphery, which improves the strength and impact resistance of the tire sidewall while ensuring the tire's water and mud drainage performance.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] 1. This utility model enhances the overall strength and impact resistance of the tire by arranging several metal rings at equal intervals inside the tire body and setting a reinforcing sleeve on the outside of the metal rings in a spiral winding manner. It can effectively resist tire damage caused by punctures and collisions from sharp objects, significantly reduce the risk of tire blowout under harsh working conditions, and ensure the safety of engineering vehicles.

[0015] 2. This utility model uses a reinforcing sleeve spirally wound on the outside of the metal ring to make the connection between the tire body and the metal ring tighter and more stable. During the operation of engineering vehicles, the tire will be subjected to various complex forces and vibrations. This structure can effectively disperse stress, reduce local stress concentration, and avoid problems such as deformation and cracking of the tire due to uneven stress, thereby extending the service life of the tire.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1 to 3 This embodiment provides an explosion-proof polyurethane tire for engineering vehicles, including a hub 1 and a tire body 2. The tire body 2 covers the outside of the hub 1. Several metal rings 3 are arranged equidistantly inside the tire body 2. The metal rings 3 are sleeved on the outside of the hub 1. A reinforcing sleeve 4 is provided inside the tire body 2. The reinforcing sleeve 4 is arranged on the outside of the several metal rings 3 in a spiral winding manner.

[0022] During the tire manufacturing process, several metal rings 3 with circular cross-sections are equidistantly arranged on the outside of the hub 1. Then, a reinforcing sleeve 4 is spirally wound around the outside of these metal rings 3. Finally, polyurethane material is cast onto the outside of the metal rings 3 and the reinforcing sleeve 4 through a casting process to form the tire carcass 2 covering the outside of the hub 1. When the tire is subjected to external forces, the metal rings 3 and the reinforcing sleeve 4 jointly bear and disperse these forces. The metal rings 3 provide a basic support frame, while the reinforcing sleeve 4 further enhances the overall strength and toughness through its spiral winding structure.

[0023] The tire body 2 is integrally formed on the outside of the metal ring 3 and the reinforcing sleeve 4 by a casting process. The casting process involves injecting liquid polyurethane material into a mold in which the metal ring 3 and the reinforcing sleeve 4 are pre-installed, allowing the polyurethane material to gradually solidify and form a tire with an integral structure on the outside of the metal ring 3 and the reinforcing sleeve 4. In this process, the polyurethane material is tightly bonded to the metal ring 3 and the reinforcing sleeve 4 without obvious delamination or gaps.

[0024] The outer surface of the tire body 2 is provided with anti-slip pattern 5. During the tire body 2 forming process, a specific anti-slip pattern 5 shape is formed on the outer surface of the tire body 2 through mold design. When the tire contacts the ground, the friction between the tire and the ground is increased.

[0025] A buffer pad 6 is provided between the wheel hub 1 and the metal ring 3. When the tire is subjected to an impact force, the buffer pad 6 will undergo elastic deformation to absorb and disperse part of the impact energy. The elastic material of the buffer pad 6 can deform accordingly according to the magnitude and direction of the impact force, thereby reducing the direct impact on the wheel hub 1 and the tire.

[0026] Both sides of the outer wall of the tire body 2 are provided with grooves 7 arranged in a ring. The width of the groove 7 gradually increases from the side near the hub 1 towards the outer ring of the tire body 2, forming a gradient groove structure. When the tire is in motion, this gradient groove structure can better withstand the pressure and maintain the structural stability of the tire body 2.

[0027] The metal ring 3 has a circular cross-section. This shape can evenly distribute stress when bearing load. When the tire is subjected to external force, the circular cross-section of the metal ring 3 can evenly transfer the force to the surrounding material, avoiding stress concentration.

[0028] The depth of the groove 7 gradually decreases from the outer periphery to the inner periphery of the tire body 2. When the tire is in motion and the tread contacts the ground and is subjected to pressure, the shallower inner periphery of the groove 7 can better withstand the pressure and maintain the structural stability of the tire body 2, while the deeper outer periphery of the groove 7 is conducive to the entry and exit of debris, and can also buffer external impacts to a certain extent.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
