Description

Technical Field

[0001] This invention relates to the field of tire technology, specifically to a tire tread pattern and tire. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are usually mounted on metal rims, supporting the vehicle body, cushioning external impacts, making contact with the road surface, and ensuring the vehicle's driving performance. Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperatures during driving. Therefore, they must have high load-bearing capacity, traction capacity, and cushioning capacity.

[0003] The tread pattern on a tire has a significant impact on its inherent characteristics. While existing tire tread patterns offer some anti-skid properties, they generally fail to provide stable grip in wet conditions, resulting in poor anti-skid performance. Furthermore, after prolonged use, the rubber layer on the tire tread wears down, affecting its anti-skid performance and requiring timely replacement, increasing driving costs. Additionally, in rainy weather with slippery roads, the large amount of water between the tires and the road surface, and its slow expulsion, greatly reduces friction, leading to skidding and potential vehicle rollovers, posing a threat to life and property.

[0004] Furthermore, to facilitate vehicle operation, asymmetrical tread patterns are typically used, meaning the left and right sides of the tire tread are asymmetrical. This ensures excellent handling during wet cornering and good water drainage. However, the design of existing asymmetrical tread patterns can easily lead to excessive differences in rigidity between the two sides of the tire, resulting in uneven wear and reducing tire lifespan and safety.

[0005] Therefore, a tire tread pattern and tire design are proposed to address the current shortcomings. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a tire tread pattern and tire.

[0007] To solve the above-mentioned technical problems, the technical solution provided by the present invention is a tire tread pattern: including a central tread area;

[0008] The central tread area includes multiple rows of V-shaped grooves evenly arranged along the circumference of the tire tread. Two parallel main grooves are provided on both sides of the central tread area, and the main grooves are arranged around the circumference of the tire tread.

[0009] It also includes tread pattern area one and tread pattern area two. Tread pattern area one is located to the left of the central tread pattern area, and the main groove is located between tread pattern area one and the central tread pattern area. Tread pattern area one includes multiple Z-shaped grooves evenly distributed along the tire circumference. Tread pattern area two is located to the right of the central tread pattern area, and the main groove is located between tread pattern area two and the central tread pattern area. Tread pattern area two includes multiple transverse grooves evenly distributed along the tire circumference.

[0010] As an improvement, the Z-shaped groove is inclined to the tread axis.

[0011] As an improvement, the inclination angle between the Z-shaped groove and the tread axis is 15° to 25°.

[0012] As an improvement, the V-shaped grooves are arranged in two rows, and the opening directions of the V-shaped grooves are consistent.

[0013] As an improvement, the transverse grooves are arranged with a linear inclination.

[0014] As an improvement, the transverse groove is inclined downwards from one end near the central pattern area to the other end.

[0015] As an improvement, the inclination angle of the transverse groove is in the range of 35° to 50°.

[0016] As an improvement, the main trench has a U-shaped cross-section.

[0017] In another aspect, the present invention discloses a tire, wherein the tire tread adopts the tire pattern described in any of the above-mentioned technical solutions.

[0018] As an improvement, the tread pattern area 1 and tread pattern area 2 on tire #1 are symmetrically arranged with the tread pattern area 1 and tread pattern area 2 on tire #2.

[0019] The advantages of this invention compared to the prior art are:

[0020] 1. The shallow groove design of the main groove ensures stable handling while greatly improving grip and, to some extent, enhancing wear resistance; the Z-shaped groove design ensures the strength between the hook and groove, reducing tread deformation wear; and by reducing tread deformation, the slippage and curling contact area is reduced, improving wear resistance. At the same time, the Z-shaped structure helps reduce tread displacement, mitigating wear caused by tread displacement, while increasing the contact area and improving tire wear resistance; in addition, the lateral groove 7 further enhances drainage performance.

[0021] 2. The Z-shaped grooves and lateral grooves are designed with the opposite inclination angle to the V-shaped grooves, which can ensure that each tread pattern makes stable contact with the ground, so that the tread blocks are evenly stressed, reducing stress concentration and tread heat generation, thereby improving both tire traction and wear resistance.

[0022] 3. By using the tire symmetrically, the driving stability and uniform wear resistance of the tire can be improved, and the phenomenon of uneven wear can be reduced. At the same time, it can avoid the problem of driving direction deviation caused by the different friction coefficients of traditional asymmetrical tires, thus improving driving safety and further reducing fuel consumption.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the invention clearer, the technical solutions of the embodiments of the invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the invention, not all embodiments. The components of the embodiments of the invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] In the description of the embodiments of the invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0029] In the description of the embodiments of the invention, "a plurality of" means at least two.

[0030] In the description of the embodiments of the invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the invention according to the specific circumstances.

[0031] Combined with appendix Figure 1-2 As shown, a tire tread pattern includes a central tread area 1; in practice, the width of the central tread area 1 accounts for 26% to 35% of the total driving area.

[0032] The central tread area 1 includes multiple rows of V-shaped grooves 2 evenly arranged along the circumference of the tire tread. In this embodiment, there are two rows of V-shaped grooves 2, and the opening directions of the V-shaped grooves 2 are consistent.

[0033] The central tread area 1 has two parallel main grooves 3 on both sides. The main grooves 3 are arranged around the circumference of the tire tread. In this embodiment, the cross-section of the main grooves 3 is U-shaped. At the same time, the main grooves 3 adopt a shallow groove design to ensure stable handling while greatly improving grip and to a certain extent improving its wear resistance.

[0034] It also includes tread pattern area 4 and tread pattern area 5. Tread pattern area 4 is located to the left of the central tread pattern area 1. The left edge of tread pattern area 4 is located at the edge of the tire crown. It can enhance the tire's drainage performance on wet roads, allowing the water film to be discharged as soon as possible. At the same time, it can improve the tire's grip on wet roads and help the tire dissipate heat.

[0035] The main groove 3 is located between the tread pattern area 4 and the central tread pattern area 1. The tread pattern area 4 includes a plurality of Z-shaped grooves 6 evenly distributed along the tire circumference. Specifically, the Z-shaped grooves 6 are inclined to the tread axis. In practice, the inclination angle between the Z-shaped grooves 6 and the tread axis can be set according to the actual situation. In this embodiment, the inclination angle between the Z-shaped grooves 6 and the tread axis is between 15° and 25°.

[0036] The uniform arrangement of the Z-shaped grooves 6 ensures the strength between the grooves and reduces tread deformation wear. Furthermore, by reducing tread deformation, the slippage and curling contact area is reduced, improving wear resistance. Simultaneously, the Z-shaped structure helps reduce tread displacement, mitigating wear caused by tread displacement, while increasing the contact area and enhancing tire wear resistance.

[0037] The second tread zone 5 is located to the right of the central tread zone 1, and the left edge of the second tread zone 5 is located at the edge of the tire crown. This can enhance the tire's drainage performance on wet roads, allowing the water film to be discharged as quickly as possible. At the same time, it can improve the tire's grip on wet roads and also help the tire dissipate heat.

[0038] The main groove 3 is located between the second tread zone 5 and the central tread zone 1. The second tread zone 5 includes a plurality of transverse grooves 7 evenly distributed along the tire circumference.

[0039] Specifically, the transverse groove 7 is arranged in a linear inclined manner. The transverse groove 7 is inclined downward from one end near the central pattern area 1 to the other end. In this embodiment, the inclination angle of the transverse groove 7 is in the range of 35° to 50°.

[0040] In practice, the lateral grooves 7 are located on the inner side of the tire. The uniform arrangement of the lateral grooves 7 can improve drainage performance. At the same time, in practice, the end of the lateral hook groove 7 near the main groove 3 can be connected to the main groove 3 to further improve its drainage performance.

[0041] In this embodiment, the Z-shaped groove 6 and the transverse groove 7 are designed with opposite inclination angles to the V-shaped groove 2, which can ensure that each pattern makes stable contact with the ground, so that the pattern blocks are evenly stressed, reducing stress concentration and tread heat generation, thereby improving both tire traction and wear resistance.

[0042] In another aspect, the present invention discloses a tire, wherein the tire tread adopts the tire pattern of any of the above-mentioned technical solutions. In practice, the tread pattern area 4 and tread pattern area 5 on the tread pattern area 1 of tire #1 are symmetrically arranged with the tread pattern area 4 and tread pattern area 5 on the tread pattern area 2 of tire #2.

[0043] In this embodiment, the tire located on the left side of the vehicle body is tire #1, and the tire located on the right side of the vehicle body is tire #2. By symmetrically setting the tread pattern area 4 and tread pattern area 5 on the tread pattern area 4 and tread pattern area 5 on the tread pattern area 2 of tire #1, the tire driving stability and tire uniform wear resistance are improved, and the phenomenon of low-side wear is reduced. At the same time, the problem of driving direction deviation caused by the different friction coefficients of traditional asymmetrical tires can be avoided, thus improving driving safety and further reducing fuel consumption.

[0044] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
