Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-belt layer tire technology, specifically a tire with a multi-belt layer design. Background Technology
[0002] The belt layer is a key component of the tire structure, mainly used to enhance the tire's strength, stability, and durability. It is an important supporting structure for the tire to bear loads and maintain its shape.
[0003] The existing belt layer design uses the same material and angle for both belt layers, with belt layer A as the first layer and belt layer B as the second. In the current design, the design schemes for belt layers A and B change synchronously for different specifications. When the performance requirements of a specification are between the weaker belt layer material a and the stronger belt layer material b, if both belt layers A and B are made of material 1, in some specifications, the tire safety factor will decrease, and insufficient tire crown rigidity will affect tire durability when facing uneven road surfaces. If both belt layers A and B are made of material b, production costs will increase, tire weight will increase, rolling resistance will increase, leading to increased fuel consumption, which is detrimental to environmental protection.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0024] In one embodiment, such as Figures 1-3 As shown, a tire employing a multi-belt layer design includes: a tire body 100, a tread 200, and a first belt layer 301. The tread 200 is disposed on the outer surface of the tire body 100, the first belt layer 301 is disposed at the bottom of the tread 200, and a second belt layer 302 is disposed at the bottom of the first belt layer 301. The first belt layer 301 and the second belt layer 302 are bonded to each other. By employing the first belt layer 301 and the second belt layer 302 with different parameters, the safety performance and durability of the tire body 100 are improved.
[0025] In one embodiment, such as Figure 1 and Figure 3 As shown, a tread rubber 400 is provided between the first belt layer 301 and the tread 200, which can provide additional strength and rigidity, and enhance the durability and performance of the tire body 100.
[0026] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the first belt layer 301 is made of a high-modulus material, such as steel wire, which can provide higher tensile strength and enhance the stability and load-bearing capacity of the tire body 100.
[0027] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the second belt layer 302 is made of a flexible material, such as polyester fiber or nylon cloth, which can absorb road vibration, disperse stress, and reduce fatigue cracks.
[0028] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the thickness of the first belt layer 301 is greater than that of the second belt layer 302. The thicker first belt layer 301 can improve the static load resistance and provide rigid support for the tire body 100. The thinner second belt layer 302 can reduce the weight of the tire body 100, reduce rotational inertia, and increase flexibility to alleviate internal fatigue caused by long-term operation.
[0029] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the weaving density of the first belt layer 301 is greater than that of the second belt layer 302. The higher density weaving of the first belt layer 301 provides stronger compression resistance, while the lower density weaving of the second belt layer 302 can reduce the amount of material used, enhance heat dissipation and flexibility, and avoid the problem of internal heat accumulation caused by excessive material stacking.
[0030] In one embodiment, such as Figure 1 , Figure 2 and Figure 3 As shown, the fiber bundle angle of the first belt layer 301 is smaller than that of the second belt layer 302. The smaller fiber bundle angle of the first belt layer 301 can resist the circumferential tension of the tire body 100, thereby enhancing the load-bearing capacity and speed stability of the tire body 100. The larger fiber bundle angle of the second belt layer 302 can enhance lateral grip and improve steering performance and cornering stability.
[0031] The above embodiments disclose a tire with a multi-belt layer design. The first belt layer 301 can provide higher tensile strength, enhance the stability and load-bearing capacity of the tire body 100, and resist the circumferential tension of the tire body 100, thereby enhancing the load-bearing capacity and speed stability of the tire body 100. The second belt layer 302 can absorb road vibration, disperse stress, reduce fatigue cracks, and enhance lateral grip, improving steering performance and cornering stability. The thicker first belt layer 301 can improve static load resistance and provide rigid support for the tire body 100. The thinner second belt layer 302 can reduce the weight of the tire body 100, reduce rotational inertia, and increase flexibility to alleviate internal fatigue caused by long-term operation. The higher density weave of the first belt layer 301 can provide stronger compression resistance, while the lower density weave of the second belt layer 302 can reduce material usage, enhance heat dissipation and flexibility, and avoid internal heat accumulation problems caused by excessive material accumulation.
[0032] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
