[0023] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0024] In one embodiment, Figure 1-Figure 2As shown, a new high-load vacuum tire bead structure includes a carcass 13, the outermost layer of the carcass 13 is provided with a sidewall 11, and a layer of rubber reinforcement layer 20 is attached between the sidewall 11 and the carcass 13;

[0025] The inner ring of the carcass 13 is provided with a spur rubber 12, the outer part of the carcass 13 is wrapped with a wire cloth 14, the triangular area of ​​the carcass 13 is provided with a soft apex rubber 15 and a hard apex rubber 16, the soft apex rubber 15 corresponds to the hard apex rubber 16, and the innermost layer of the carcass 13 is provided with a wire ring 17.

[0026] In this embodiment, the bead seal 12 fits tightly against the rim, forming a reliable seal that prevents gas leakage from the tire. The tight connection between the bead ring 17 and the rim ensures the tire's stability and safety during driving. The carcass 13 and the wire wrap 14 jointly bear the tire's load. The interaction between the soft apex 15 and the hard apex 16 further optimizes stress distribution, reducing heat and wear caused by deformation. The combination of the sidewall 11 and the profiled rubber reinforcement layer 20 improves the tire's wear resistance and extends its service life.

[0027] In one embodiment, Figure 1-Figure 2 As shown, the wire ring 17 is wrapped with the carcass 13, the wire cloth 14, and the nylon reinforcement layer 19 from the inside to the outside. The inner side of the wire ring 17 is provided with an inner liner 18, and the outer side of the inner liner 18 is wrapped with the profile reinforcement layer 20, the end rubber 12, and the sidewall 11 from the inside to the outside.

[0028] The bead ring 17 is wrapped with a carcass 13, a wire cloth 14, and a nylon reinforcement layer 19 from the inside out, and an inner liner 18 is provided to ensure the stability and durability of the bead ring. The provision of the inner liner 18 further enhances the sealing and protective effect.

[0029] In one embodiment, Figure 1-Figure 2 As shown, two layers of nylon reinforcement layers 19 are attached between the inner liner 18 and the carcass 13 and the wire cloth 14.

[0030] The high-strength nylon reinforcement layer 19 significantly improves the tire's load-bearing capacity and impact resistance in key areas. The addition of two layers of nylon reinforcement 19 doubles this effect, ensuring the tire maintains stability and safety even at high speeds and under heavy loads.

[0031] In one embodiment, Figure 2 As shown, the cord angle of the two nylon reinforcement layers 19 is 15-55 degrees, the width is 50-120 mm, and the inner and outer layers are staggered by 10-15 mm and are attached in a straight line.

[0032] By optimizing the cord angle 15-55° and width 50-120mm, and the inner and outer layer stagger difference 10-15mm, the load capacity and structural strength of the tire are significantly improved.

[0033] In one embodiment, as shown in Figure 2 One layer of the nylon reinforcing layer 19 wraps the inner end of the steel cord cover 14 and the outer end of the tire body 13, and the other layer of the nylon reinforcing layer 19 is located directly below the bead wire 17.

[0034] One layer of the nylon reinforcing layer 19 wraps the end of the steel cord cover 14 and the tire body 13, further enhancing the strength of the connection part. Another layer of the nylon reinforcing layer 19 is located directly below the bead wire 17, which uses the clamping force of the bead wire 17 to lock the two layers of nylon reinforcing layer cord 19, reducing the stress concentration at the end.

[0035] In one embodiment, as shown in 2, the inner end point position of the two layers of the nylon reinforcing layer 19 cord is 15-25mm away from the inner end of the steel cord cover 14, and the outer end point position of the two layers of the nylon reinforcing layer 19 cord is 15-25mm away from the outer end of the tire body 13.

[0036] The inner end point position of the two layers of the nylon reinforcing layer 19 cord is 15-25mm away from the inner end of the steel cord cover 14, and the outer end point position of the two layers of the nylon reinforcing layer 19 cord is 15-25mm away from the outer end of the tire body 13. Such design effectively disperses the stress generated during tire running.

[0037] In one embodiment, as shown in Figure 2 The two layers of the nylon reinforcing layer 19 are located between the sidewall 11 and the type glue reinforcing layer 20, and the nylon reinforcing layer 19 is 40-60mm away from the outer end of the tire body 13.

[0038] The nylon reinforcing layer 19 is located between the sidewall 11 and the type glue reinforcing layer 20, and is 40-60mm away from the outer end of the tire body 13, which ensures the maximization of the reinforcing effect.

[0039] In one embodiment, as shown in 2, the thickness of the type glue reinforcing layer 20 is 3-8mm, and the width is 60-100mm.

[0040] The thickness of the type glue reinforcing layer 20 is designed to be 3-8mm, and the width is 60-100mm, which not only ensures the rigidity and wear resistance of the sidewall, but also avoids excessive increase of tire weight and rolling resistance.

[0041] The above embodiments disclose a new structure of high-load vacuum tire bead, in which the bead rubber 12 is tightly attached to the rim to form a reliable sealing structure, preventing the leakage of internal gas of the tire and ensuring the stability of the tire during running.

[0042] The close connection between the wire ring 17 and the rim further enhances the stability of the tire and enables the tire to withstand higher loads.

[0043] The addition of the nylon reinforcement layer 19, especially its two-layer design, effectively disperses the stress generated by the tire during driving and reduces tire damage caused by stress concentration.

[0044] At the same time, the combination of the nylon reinforcement layer 19 and the rubber reinforcement layer 20 improves the wear resistance of the tire and extends the service life of the tire.

[0045] The wire cloth 14 and the wire ring 17 jointly bear the load of the tire, ensuring the high load-bearing capacity of the tire.

[0046] The design of the two-layer nylon reinforcement layer 19, especially its optimized cord angle and width, and the staggered and stepped contact method of the inner and outer layers, significantly improves the structural strength of the tire.

[0047] The synergistic effect of various components such as the carcass 13, sidewall 11, profiled rubber reinforcement layer 20, wire cloth 14, soft apex rubber 15, hard apex rubber 16 and nylon reinforcement layer 19 forms a complete reinforcement system, further improving the overall performance of the tire.

[0048] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
