[0002] With the rapid development of the global automotive market and the continuous growth of transportation demand, the demand for heavy-duty transport vehicles is also increasing, especially for medium- and long-distance heavy-duty transport vehicles. Because medium- and long-distance heavy-duty transport vehicles face multiple challenges such as high loads, high speeds, and complex road conditions, and tires, as the only component in contact with the ground, have a significant impact on vehicle transport safety, higher requirements are placed on various tire performance aspects, especially tire handling, durability, and anti-skid performance.

[0003] Tire tread design has a significant impact on vehicle transportation safety. Currently, the tread design of heavy-duty truck tires typically incorporates main tread grooves and fine grooves on the tread blocks to enhance handling performance and wet traction, ensuring driving safety. However, after a certain mileage, the fine grooves on the tread of these heavy-duty tires wear out, significantly reducing the tire's wet traction and handling stability, lowering the safety factor, reducing tire mileage, and ultimately shortening tire lifespan.

[0004] Therefore, a heavy-duty radial tire tread pattern is needed to meet modern transportation requirements. Utility Model Content

[0006] This utility model proposes a heavy-duty radial tire tread pattern and tire, which solves the technical problem that after a certain mileage, the fine grooves of the tread of existing heavy-duty tires will be worn out, resulting in a significant decrease in the tire's wet skid resistance and handling stability, a reduced safety factor, a reduced tire mileage, and a reduced tire lifespan. It has the characteristics of effectively improving handling, durability and wet skid resistance, extending service life, and meeting the needs of modern transportation.

[0007] This utility model discloses a radial tire pattern for heavy-duty vehicles, including multiple longitudinal tread grooves extending circumferentially along the tread and multiple tread blocks divided by the longitudinal tread grooves. Each tread block is provided with multiple 3D interconnected steel sheet groups. Each 3D interconnected steel sheet group includes multiple 3D steel sheets arranged in a staggered manner along the horizontal line of the tread. The angle between the 3D steel sheets and the horizontal line of the tread is 10°-25°. The depth of the 3D steel sheets is 1 / 2-4 / 5 of the depth of the longitudinal tread grooves.

[0008] In some embodiments, the tread blocks include central tread blocks located on both sides of the tread centerline and edge tread blocks located on both sides of the tire shoulders, and the width of the edge tread blocks is the same as the width of the central tread blocks.

[0009] In some embodiments, the 3D interconnected steel sheet assembly includes a first 3D interconnected steel sheet assembly and a second 3D interconnected steel sheet assembly symmetrically arranged on the central patterned block near the two edges of the longitudinal patterned groove, and a third 3D interconnected steel sheet assembly arranged on the edge patterned block near the edge of the longitudinal patterned groove.

[0010] In some embodiments, the first 3D interconnected steel sheet group and the second 3D interconnected steel sheet group are connected by a third central fine groove provided on the central patterned block.

[0011] In some embodiments, a first central fine groove and a second central fine groove are also provided between adjacent third central fine grooves on the central patterned block, and the first central fine groove and the second central fine groove have the same depth and width.

[0012] In some embodiments, a plurality of first edge fine grooves are provided at intervals on the edge pattern block, and a second edge fine groove is provided between adjacent first edge fine grooves. The depth and width of the first edge fine grooves and the second edge fine grooves are the same.

[0013] In some embodiments, multiple scallop shell-like bionic heat dissipation grooves are provided on the outer side of the edge patterned block, and multiple serrated protrusions are provided inside the heat dissipation grooves.

[0014] In some embodiments, the longitudinal patterned grooves have a zigzag structure, the groove wall angle is 26°-32°, and the bottom of the groove adopts a full arc design.

[0015] In some embodiments, the longitudinal tread groove includes a central tread groove located at the center line of the tread and side tread grooves located on both sides of the central tread groove, wherein the central tread groove and the side tread grooves have the same depth, and the width of the central tread groove is greater than the width of the side tread grooves.

[0016] In another aspect, this utility model also discloses a tire, on which the above-mentioned heavy-duty radial tire pattern is provided on the tire tread.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] (1) By setting multiple 3D interconnected steel sheet groups on the tread blocks, this utility model improves the structural rigidity, traction and anti-slip performance of the tire, making the tire perform well under complex road conditions, especially under high speed and high load, with extremely high stability and safety, suitable for medium and long-distance transport vehicles, meeting the high requirements of the modern transportation industry for tires, and helping to improve transportation efficiency and reduce operating costs.

[0019] (2) This utility model has multiple fine grooves on the central tread block and the edge tread block, which helps to quickly remove the water film between the tire contact surface and the road surface, especially improving the wet and slippery performance on wet, waterlogged or rainy roads; the fine grooves can reduce the slippage between the tire and the road surface by accelerating the drainage of water, improving grip, reducing the risk of slippage, and improving the tire's flexibility and handling response, especially the handling stability when turning; moreover, the design of the fine grooves also increases the edge friction on the tire contact surface, thereby improving steering stability and handling, making the vehicle more stable when driving at high speed or making sharp turns.

[0020] (3) The three-line longitudinal tread groove design of this utility model not only enhances the tread drainage function and ensures good grip on wet and slippery roads, but also effectively reduces the formation of water film and reduces the slipping phenomenon under wet and slippery conditions. It is suitable for medium and long-distance transport vehicles, especially under long-distance driving conditions such as highways and national roads. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," and "third" may explicitly or implicitly include one or more of that feature. The term "longitudinal" refers to the direction in which the tire rolls; the term "lateral" refers to the direction perpendicular to the mid-surface of the tire.

[0031] This utility model provides a heavy-duty radial tire pattern and tire for all wheel positions. The tire pattern is suitable for all wheel positions of medium and long-distance vehicles traveling on highways and national roads. By adopting a design applicable to all wheel positions, it ensures that it can provide stable performance in different positions such as drive wheels, guide wheels and trailer wheels. The tire pattern and structural design can be optimized to adapt to various load requirements in different wheel positions of the vehicle, thereby improving driving safety and stability. Figure 1 This is a schematic diagram of the tread pattern for a heavy-duty radial tire with all wheel positions, according to an embodiment of the present invention. (Reference) Figure 1 As shown, the tread pattern of this heavy-duty radial all-wheel tire includes multiple longitudinal tread grooves extending circumferentially along the tread and multiple tread blocks divided by the longitudinal tread grooves. Each tread block is provided with multiple 3D interconnected steel sheet groups. (Refer to...) Figure 2 and Figure 3As shown, each 3D interconnected steel sheet group includes multiple 3D steel sheets arranged in a staggered pattern along the horizontal line of the tire tread. The angle between the 3D steel sheets and the horizontal line of the tire tread is 10°-25°. The depth of the 3D steel sheets is 1 / 2-4 / 5 of the depth of the longitudinal tread grooves. The width of the 3D steel sheets is 0.6-1.2 mm. The bending angle θ of the 3D steel sheets is 95°-130°. The bending width W3 of the 3D steel sheets is 1.5-3 mm. By setting multiple 3D interconnected steel sheet groups on the tread blocks, the structural rigidity, traction, and anti-slip performance of the tire are improved, enabling the tire to perform excellently under complex road conditions, especially exhibiting extremely high stability and safety under high-speed driving and high load.

[0032] This embodiment of the utility model's radial tire tread pattern includes central tread blocks 2 located on both sides of the tread centerline and edge tread blocks 4 located on both tire shoulders. The width ratio of the edge tread block 4 (W1:W2) to the width of the central tread block 2 (W2) is W1:W2 = 1:1. This structural design makes the rigidity and stress distribution of each part of the tread more uniform. The longitudinal traction provided by the central tread block 2 ensures that the tire can provide stable power transmission when driving in a straight line, while the edge tread blocks 4 enhance the lateral traction of the tire, effectively improving the tire's grip when cornering and preventing slippage or sideslip. This allows the tire to maintain strong grip on wet, muddy, or dry roads. The 1:1 tread block width ratio design ensures the tire's handling stability in all wheel positions, providing the same handling feedback and stability whether driving or towing, avoiding inconsistencies caused by differences in wheel positions.

[0033] In this embodiment of the utility model, the central tread block 2 of a heavy-duty radial tire features symmetrical first 3D interconnected steel sheet groups 8 and second 3D interconnected steel sheet groups 9 arranged near the two edges of the longitudinal tread groove. The first 3D interconnected steel sheet groups 8 and 9 are connected by a third central fine groove 7. The first 3D interconnected steel sheet group 8 comprises multiple first 3D steel sheets that are not on the same horizontal line. These first 3D steel sheets are staggered upwards along the tread horizontal line from the center of the central tread block to the longitudinal tread groove. The angle between the first 3D steel sheet and the tread horizontal line is 10°-25°, the width of the first 3D steel sheet is 0.6-1.2 mm, the depth of the first 3D steel sheet is 1 / 2-4 / 5 of the depth of the longitudinal tread groove, the bending angle of the first 3D steel sheet is 95°-130°, and the bending width of the first 3D steel sheet is 1.5-3 mm. The edge patterned block 4 is equipped with a third 3D interconnected steel sheet group 10 near the edge of the longitudinal patterned groove.

[0034] In this embodiment of the utility model, on the central tread block 2 of a heavy-duty radial tire, a first central fine groove 5 and a second central fine groove 6 are also provided at intervals between adjacent third central fine grooves 7. The depth of both the first central fine groove 5 and the second central fine groove 6 is 2-3mm, and the width of both the first central fine groove 5 and the second central fine groove 6 is 0.6-1.5mm. The first central fine groove 5 has a zigzag structure, and its two ends are respectively connected to adjacent longitudinal tread grooves; the two ends of the second central fine groove 6 are closed structures. On the edge tread block 4, a first edge fine groove 11 is provided between adjacent third 3D interconnected steel sheet groups 10, and the end of the third 3D interconnected steel sheet group 10 away from the longitudinal tread groove is connected to the second edge fine groove 12. Both the first edge groove 11 and the second edge groove 12 are semi-closed structures. The depth of both the first edge groove 11 and the second edge groove 12 is 2-3 mm, and the width of both the first edge groove 11 and the second edge groove 12 is 0.6-1.5 mm. By setting fine grooves on the central tread block 2 and the edge tread block 4, it helps to quickly expel the water film between the tire contact patch and the road surface, especially improving wet and slippery performance on wet, waterlogged, or rainy roads. By accelerating the drainage of accumulated water, the fine grooves can reduce the slippage between the tire and the road surface, improve grip, reduce the risk of slippage, and improve the tire's flexibility and handling response, especially the handling stability during cornering. Moreover, the design of the fine grooves increases the edge friction on the tire contact surface, thereby improving steering stability and handling, making the vehicle more stable when driving at high speeds or making sharp turns.

[0035] In this embodiment of the invention, multiple fan-shaped biomimetic heat dissipation grooves 13 are provided on the outer side of the edge tread block 4 of the heavy-duty radial tire pattern. The depth of the heat dissipation grooves 13 is 2-4mm. (Reference) Figure 4 As shown, the heat dissipation groove 13 has multiple serrated protrusions resembling scallop shells, with a height of 0.5-1.0 mm. Through this biomimetic heat dissipation groove 13 design, heat can be dissipated from the tire shoulder area, preventing localized overheating and reducing performance degradation or damage caused by overheating. This also reduces the occurrence of tire shoulder gaps and shoulder delamination. Simultaneously, the serrated protrusions protect the tire shoulder, preventing damage to the bottom of the heat dissipation groove 13 from external hard stones, improving the puncture resistance of the bottom of the heat dissipation groove 13, and effectively preventing deformation and cracking of the groove bottom. This results in higher tire safety, better durability, and a longer service life.

[0036] In this embodiment of the utility model, the longitudinal tread grooves of the heavy-duty radial all-wheel tire have a zigzag structure, which provides the tire with excellent directional performance and handling stability, while also ensuring excellent anti-slip performance. Simultaneously, it increases the rigidity of the tread blocks and improves the tire's wear resistance. The groove wall angle is 26°-32° (reference). Figure 5As shown, the bottom of the longitudinal tread grooves adopts a full-circular arc design. This structural design makes the force distribution of the longitudinal tread groove walls more uniform in the circumferential direction of the tire, reducing the occurrence of cracks at the bottom of the longitudinal tread grooves. At the same time, it can reduce the noise generated during tire driving, effectively prevent stones from getting stuck, and improve the tire's self-cleaning ability. The longitudinal tread grooves include the central tread groove 1 located at the center line of the tread and the side tread grooves 3 located on both sides of the central tread groove 1. The central tread groove 1 and the side tread grooves 3 have the same depth, and the width of the central tread groove 1 is 1-1.5mm wider than the width of the side tread grooves 3. This design reduces the width difference between the central tread groove 1 and the side tread grooves 3 after the tire is inflated, so that the tread pressure is evenly transferred, preventing localized uneven wear and improving the tire's wear resistance.

[0037] This utility model also provides a tire, the tire tread being provided with the aforementioned heavy-duty radial tire pattern for all wheel positions. For example... Figure 6 The diagram shows the structure of the tire after a certain mileage, with three longitudinal grooves and a 3D interconnected steel sheet group remaining. At this point, the tire still has a certain degree of wear resistance and wet skid resistance, reducing the frequency of tire replacement and bringing higher cost performance to car owners.

[0038] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
