Description

Technical Field

[0001] This utility model relates to the field of tire design and manufacturing technology, specifically a lightweight woven belt layer for tires. Background Technology

[0002] The belt layer used in tires is designed as a single or multiple parallel metal strip structure with different angles, which is inserted between the tire carcass structure and the tread structure. Traditional belt structures are not only heavy, but the high friction and high heat generation caused by the metal properties can easily lead to quality and safety issues such as shoulder gaps after high-speed and long-term driving.

[0003] Traditional metal belt layers are made by twisting at least two monofilaments into a single steel wire under a certain pre-tension. The twisted steel wires need to be arranged at a certain density in a spindle room and then calendered and coated with rubber. The coated fabric needs to be further cut by a cutting machine before it can be used on tires. The product specifications are limited and the production process is complex. Traditional belt layer processing is complicated and heavy. Tires produced from this process are prone to quality problems such as shoulder gaps after high-speed and long-term driving.

[0017] In one alternative: the material of the impregnation coating is a phenolic resin composite adhesive.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] This invention, by setting a braidable belt layer, can effectively enhance the overall structural strength and stability of the tire, improve the adhesion between the belt layer and the rubber, and set the metal wires into a triangular mesh structure, which can evenly distribute the load and stress, avoid local breakage or deformation caused by stress concentration, increase the effective bonding area with the rubber, reduce the heat loss generated by continuous friction between metal filaments under a certain load, and at the same time reduce the occurrence of brittle fracture of the tire belt layer under compression, thereby improving the tire's safety and service life.

[0024] 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.

[0025] In one embodiment, such as Figures 1-3As shown, a lightweight woven belt layer for a tire includes: a tread 100, a mesh woven belt layer 200, a tire body 300, and a plurality of metal wires 400. The mesh woven belt layer 200 is disposed below the tread 100, the tire body 300 is disposed below the mesh woven belt layer 200, and the metal wires 400 are disposed inside the mesh woven belt layer 200. Micro-gaps 500 are provided between the plurality of metal wires 400. The mesh woven belt layer 200 is protected by a protective layer 100, and the micro-gaps 500 help to dissipate heat quickly.

[0026] In one embodiment, such as Figure 2 As shown, multiple metal wires 400 are intersected and arranged in a triangular grid shape. After processing by special equipment, they form a mesh-like belt layer structure that interlocks with each other, increasing the effective area of ​​bonding with rubber, reducing heat loss caused by continuous friction between metal filaments under a certain load, and reducing the occurrence of brittle fracture of the tire belt layer under compression, thereby improving tire safety and service life.

[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the diameter of the metal wire 400 ranges from 0.01 to 0.1 mm; the appropriate diameter can be selected according to different needs. Small diameter wires (such as 0.01 to 0.05 mm) are used for lightweight requirements, such as small passenger car tires, while large diameter wires (such as 0.06 to 0.1 mm) are used for heavy truck or off-road vehicle tires with greater load-bearing requirements.

[0028] In one embodiment, such as Figure 1 and Figure 2 As shown, the surface of the mesh braided belt layer 200 is provided with a multi-layer impregnation coating 600; this enhances adhesion and covers the entire mesh surface, providing additional protection.

[0029] In one embodiment, such as Figure 1 and Figure 3 As shown, the surface of the metal wire 400 is provided with a nano-coating; this protects the metal wire, improves its corrosion resistance, reduces the coefficient of friction, and reduces heat accumulation and consumption during high-temperature driving.

[0030] In one embodiment, such as Figure 1 and Figure 2 As shown, the thickness of the mesh braided belt layer 200 ranges from 0.02 to 0.3 mm, the width ranges from 10 to 500 mm, and the length ranges from 10 to 3000 mm; to meet the needs of different tire models, multiple steel wire units are woven into an interlocking mesh belt layer by special equipment, and the width and length of the belt layer can be customized according to requirements during the production process.

[0031] In one embodiment, such as Figure 2 As shown, the material of the impregnated coating 600 is a phenolic resin composite material; it blocks the corrosion of metal wires by air, moisture and chemicals, prevents rust and fatigue cracks, and improves the corrosion resistance of the tire.

[0032] The above embodiments disclose a lightweight woven belt layer for tires. By processing metal steel wires 400 using special equipment, a mesh-like belt layer structure is formed through interlocking. This increases the effective bonding area with rubber, reduces heat loss caused by continuous friction between metal filaments under certain loads, and reduces brittle fracture of the tire belt layer under compression. This improves tire safety and service life. Single or multiple steel wires with a diameter of 0.01~0.1mm are processed using specific logic and pre-modification techniques and special equipment to form an interlocking mesh-like belt layer structure. The completed mesh belt layer structure, after pre-impregnation with a special rubber compound, can be inserted between the tire carcass structure and tread structure in one or more layers.

[0033] 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.
