Description

Technical Field

[0001] This utility model relates to the field of non-pneumatic explosion-proof tires for industrial and mining applications, and in particular to a segmented tire carcass structure for such tires. Background Technology

[0002] Industrial and mining tires are tires specifically designed for use in industrial vehicles, mining machinery, and engineering equipment in industrial and mining environments. These tires are mainly used in places that need to withstand high loads, complex road conditions, and extreme working conditions, such as mines, construction sites, ports, warehouses, and heavy machinery. Industrial and mining tires typically have high wear resistance, impact resistance, high temperature resistance, and puncture resistance to cope with harsh working environments.

[0003] Existing industrial and mining tires still have some problems during use. For example, most existing industrial and mining tires are solid tires. Although solid tires absorb impact and provide cushioning through the compression and deformation of rubber materials, their cushioning effect is often poor under high-speed driving or heavy load conditions, and they cannot effectively reduce impact force, which affects the comfort and safety of driving. In addition, the high hardness of solid tires may increase equipment vibration, affect handling performance, and thus affect work efficiency.

[0004] To address these issues, we provide a segmented tire carcass structure for non-pneumatic explosion-proof tires used in industrial and mining applications. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the existing technology has the disadvantage of poor cushioning performance. To this end, we propose a segmented tire carcass structure for non-pneumatic explosion-proof tires for industrial and mining applications.

[0006] To achieve the above objectives, this application adopts the following technical solution: a segmented tire carcass structure for a non-pneumatic explosion-proof tire for industrial and mining applications, including a tread, a supporting base provided in the inner cavity of the tread, honeycomb holes being provided around the inner cavity of the supporting base, an installation flange being provided in the inner cavity of the supporting base, the supporting base including an inner supporting layer, an energy dissipation layer being fixedly connected to one side of the inner supporting layer, and a fatigue resistance layer being fixedly connected to one side of the energy dissipation layer.

[0007] Preferably, the mounting flange surface is provided with a mesh groove, which is used to stably connect the mounting flange to the support base.

[0008] Preferably, threaded blind holes are provided on both sides of the inner cavity of the mounting flange, and the number of threaded blind holes is 12.

[0009] Preferably, the inner support layer is made of polyurethane, the energy dissipation layer is made of polyurethane elastomer, and the fatigue resistance layer is made of natural rubber.

[0010] Preferably, the mounting flange is made of high-strength steel and is used to connect the tire body and the wheel hub.

[0011] Preferably, the inner cavity of the tire tread is fitted to the surface of the support base, and the inner cavity of the support base is fitted to the mesh grooves on the surface of the mounting flange.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model effectively improves the overall performance of the tire by setting a unique support matrix in the inner cavity of the tire tread, and opening honeycomb holes in the matrix and constructing a segmented structure composed of an inner support layer, an energy dissipation layer and a fatigue resistance layer. The support matrix and its internal honeycomb holes together form a highly efficient mechanical buffer system, which can absorb and dissipate the impact energy from the road surface through its structural deformation, thereby significantly improving the tire's buffering and shock absorption performance. It overcomes the inherent defects of traditional solid tires, such as poor buffering effect and low driving comfort. At the same time, this segmented tire structure can maintain high load-bearing capacity and structural stability while providing excellent buffering, ensuring the operational stability and safety of mining vehicles under heavy load and high-speed operating conditions.

[0014] 2. This utility model achieves reliable force flow transmission and transition between the rigid wheel hub and the flexible tire carcass by adopting a design that uses an internal mounting flange and a mesh groove to achieve a stable connection with the support base. The mesh groove design on the mounting flange, combined with the support base material, forms a mechanical interlocking effect that surpasses traditional bonding, greatly enhancing the strength and anti-peeling ability of the bonding interface, avoiding stress concentration, and thus improving the structural reliability and durability of the entire tire assembly. In addition, the functional layers of the support base adopt differentiated designs in terms of materials and functions, so that they can optimally undertake the tasks of support, energy absorption and deformation resistance, working together to extend the service life of the tire in harsh industrial and mining environments.

[0021] Based on the technical solution of this utility model, without changing the essential spirit of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction of the technical solution of this utility model.

[0022] Example 1

[0023] Please see Figures 1-4 This utility model is a segmented tire body structure for a non-pneumatic explosion-proof tire for industrial and mining applications. It includes a tread 1, a support base 2 is provided in the inner cavity of the tread 1, honeycomb holes 3 are provided around the inner cavity of the support base 2, an installation flange 4 is provided in the inner cavity of the support base 2, the support base 2 includes an inner support layer 5, an energy dissipation layer 6 is fixedly connected to one side of the inner support layer 5, and a fatigue resistance layer 7 is fixedly connected to one side of the energy dissipation layer 6.

[0024] Specifically: the tread 1 is an existing rubber structure, the support base 2 is used to fill the gaps inside the tread 1 and can withstand the external forces on the tread 1. The honeycomb holes 3 enable the support base 2 to buffer vibration through its own elasticity and have a certain degree of elasticity to ensure the stability of the tire support. The mounting flange 4 is used to install the tread 1 and the wheel hub. The inner support layer 5, energy dissipation layer 6 and fatigue resistance layer 7 can buffer the forces borne by the tread 1 through their own performance.

[0025] Example 2

[0026] Please see Figures 1-4Based on Example 1, a mesh groove 8 is provided on the surface of the mounting flange 4. The mesh groove 8 is used to stably connect the mounting flange 4 and the support base 2. Threaded blind holes 9 are provided on both sides of the inner cavity of the mounting flange 4. There are 12 threaded blind holes 9. The inner support layer 5 is made of polyurethane, the energy dissipation layer 6 is made of polyurethane elastomer, the fatigue resistance layer 7 is made of natural rubber, and the mounting flange 4 is made of high-strength steel. The mounting flange 4 is used to connect the tire body and the wheel hub. The inner cavity of the tire tread 1 is in contact with the surface of the support base 2, and the inner cavity of the support base 2 is in contact with the mesh groove 8 on the surface of the mounting flange 4.

[0027] Specifically: the mesh grooves 8 form an interlaced grid, allowing the subsequently injected polyurethane elastomer to completely encapsulate and penetrate them, forming an extremely strong mechanical interlock after curing, ensuring effective force transmission rather than relying solely on chemical adhesion. The 12 threaded blind holes 9 allow the mounting flange 4 to be installed to the wheel hub, providing sufficient clamping force and shear resistance. The polyurethane inner support layer 5 provides the primary mechanical strength, resisting the enormous pressure and deformation generated by heavy loads, ensuring the overall structural stability of the tire. The polyurethane elastomer energy dissipation layer 6 buffers and resists the forces exerted on the supporting substrate 2, while the natural rubber fatigue resistance layer 7 possesses excellent elasticity and crack growth resistance. This means it can quickly recover its original shape after deformation and is not prone to cracking due to repeated bending.

[0028] Working Principle: When the tire rolls on a mining road and bears a load, the tread 1 first contacts the ground and impacts, transmitting the force to the support base 2 inside its cavity. The honeycomb structure 3, which is evenly distributed inside the support base 2, then undergoes elastic deformation. Each honeycomb unit responds independently to the impact, effectively dispersing stress. The impact energy is further transmitted to the segmented structure composed of an inner support layer 5, an energy dissipation layer 6, and a fatigue resistance layer 7. The inner support layer 5 provides high rigidity support and maintains overall shape stability. The energy dissipation layer 6 converts most of the impact kinetic energy into heat energy dissipation through the high damping characteristics of the material. The fatigue resistance layer 7 undergoes large deformation to adapt to uneven road surfaces and rebounds quickly. At the same time, the mounting flange 4 forms a mechanical interlock structure with the support base 2 through the mesh grooves 8 on its surface, ensuring that the impact force is smoothly transmitted from the flexible tire body to the rigid wheel hub. Throughout the process, the functional layers work together to ensure both the tire's cushioning comfort and ground stability, as well as the structural reliability and fatigue life under high loads, ultimately achieving continuous, safe, and stable operation in extreme mining environments.

[0029] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
