[0030] To address the problem that existing tires have insufficient drainage capacity and significant water film effect on wet and slippery roads, which affects driving safety, this application provides a tire tread structure and a tire having the same.

[0031] like Figures 1 to 3 As shown, the tire tread structure includes at least two grooves 10, at least two tread blocks 30, and a sheet-like structure assembly. The at least two grooves 10 are spaced apart along the tire's central axis, and each groove 10 extends circumferentially along the tire. The ratio of the width w of each groove 10 to the width W of the tire's running surface 20 is greater than or equal to 0.055 and less than or equal to 0.06. The at least two tread blocks 30 are spaced apart along the tire's central axis, with at least one groove 10 between adjacent tread blocks 30 and at least one tread block 30 between adjacent grooves 10. The sheet-like structure assembly is disposed on the groove wall of at least one groove 10 near the tire shoulder 50. The sheet-like structure assembly includes a plurality of sheet-like structures 40 spaced apart circumferentially along the tire.

[0032] By applying the technical solution of this embodiment, the aforementioned arrangement of at least two grooves 10 ensures sufficient water storage space on wet and slippery road surfaces, increasing the water storage and drainage capacity per unit time during rapid tire rolling. This effectively removes accumulated water, reduces the water film effect, and thus solves the problem in the prior art where tires have insufficient drainage capacity and a significant water film effect on wet and slippery road surfaces, affecting driving safety. Simultaneously, the grooves 10 and the sheet-like structure 40 increase the roughness of the tire surface, improving the tire's grip on wet and slippery road surfaces, thereby enhancing driving safety.

[0033] In this embodiment, there are four grooves 10, which are spaced apart along the central axis of the tire.

[0034] It should be noted that the number of grooves 10 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, there may be three, five, six, or more grooves 10.

[0035] In this embodiment, the ratio of the width w of each groove 10 to the width W of the tire's running surface 20 is 0.057, to ensure that the groove 10 can provide sufficient water storage space on wet and slippery surfaces, thereby improving the water storage and drainage capacity per unit time when the tire is rolling rapidly.

[0036] It should be noted that the ratio of the width w of each groove 10 to the width W of the tire's tread surface 20 is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the ratio of the width w of each groove 10 to the width W of the tire's tread surface 20 is 0.056, 0.058, or 0.059.

[0037] In this embodiment, the sheet-like structure group is disposed on the groove walls of the two grooves 10 near the tire shoulder 50. This not only increases the roughness of the tire and breaks the water film, but also ensures that the rigidity of the entire tread transitions smoothly from the center to both sides, reducing uneven wear caused by uneven force.

[0038] It should be noted that the placement of the sheet-like structure group is not limited to this and can be adjusted according to working conditions and usage requirements.

[0039] In other embodiments not shown in the accompanying drawings, the sheet-like structure group is disposed on at least one tread block near the tire shoulder.

[0040] In other embodiments not shown in the accompanying drawings, a portion of the sheet-like structure group is disposed on at least one tread block near the tire shoulder, and another portion of the sheet-like structure group is disposed on the groove wall of at least one groove near the tire shoulder.

[0041] Optionally, the thickness of each sheet structure 40 is greater than or equal to 0.5 mm and less than or equal to 0.9 mm. In this way, the above-mentioned thickness range can ensure the strength of the sheet structure 40, prevent it from wearing out prematurely during driving, and increase the contact area between the tire and the ground, thereby improving grip and significantly enhancing the vehicle's driving safety and handling performance.

[0042] In this embodiment, the thickness of each sheet structure 40 is 0.7 mm, so that the rigidity of the tread block transitions smoothly from the center to both sides, reducing uneven wear caused by uneven force, thereby improving the tire's anti-wear performance.

[0043] It should be noted that the thickness of each sheet structure 40 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the thickness of each sheet structure 40 is 0.55mm, 0.60mm, 0.65mm, 0.75mm, 0.80mm, or 0.85mm.

[0044] like Figure 1 As shown, at least two grooves 10 include a first groove 11, a second groove 12, and two third grooves 13. The first groove 11 is located on one side of the center surface CS of the tire. The second groove 12 is located on the other side of the center surface CS. One third groove 13 is located between a tire shoulder 50 and the first groove 11, and another third groove 13 is located between another tire shoulder 50 and the second groove 12. A sheet-like structure is disposed on the groove wall of at least one third groove 13. This arrangement of multiple grooves not only ensures that the tire can effectively expel water during rapid rolling, reducing the water film effect, but also effectively disperses the lateral forces of the tire during cornering, enhancing the lateral stability of the tire.

[0045] In this embodiment, the first groove 11 and the second groove 12 are symmetrically arranged about the central plane CS. One third groove 13 is located on the side of the first groove 11 away from the central plane CS, and the other third groove 13 is located on the side of the second groove 12 away from the central plane CS. The two third grooves 13 are symmetrically arranged about the central plane CS. Each of the two third grooves 13 is provided with a sheet-like structure group. The widths of the first groove 11, the second groove 12, and the third groove 13 are all the same.

[0046] like Figure 1 As shown, at least two tread blocks 30 include a first tread block 31, a second tread block 32, a third tread block 33, and a fourth tread block 34. The first tread block 31 is located between a first groove 11 and a second groove 12; the second tread block 32 is located between the second groove 12 and a third groove 13; the third tread block 33 is located between the first groove 11 and the third groove 13; and the fourth tread block 34 is located between a tire shoulder 50 and a third groove 13. The ratio of the width w1 of the fourth tread block 34 to the width w2 of the second tread block 32 is greater than or equal to 1.35 and less than or equal to 1.55; and / or the ratio of the width w1 of the fourth tread block 34 to the width w3 of the first tread block 31 is greater than or equal to 1.35 and less than or equal to 1.55; and / or the ratio of the width w1 of the fourth tread block 34 to the width w4 of the third tread block 33 is greater than or equal to 1.35 and less than or equal to 1.55. In this way, the aforementioned width ratio design optimizes the tire's contact patch shape, improves its adaptability to different road conditions, and provides better traction. Simultaneously, by dividing multiple tread blocks 30 into center tread blocks and shoulder tread blocks, and ensuring the width and rigidity of the shoulder tread blocks through the width ratio between the shoulder and center tread blocks, the uneven distribution of lateral forces during cornering reduces irregular tire wear, thereby improving the tire's resistance to uneven wear.

[0047] In this embodiment, the tread block layout is optimized according to the different force conditions of the tire center and both sides during driving. The first tread block 31, the second tread block 32 and the third tread block 33 are used as the center tread blocks, and the fourth tread block 34 is used as the shoulder tread blocks, and there are two of them. The width ratio of the shoulder tread blocks to the center tread blocks is 1.46:1, thereby ensuring the width and rigidity of the shoulder tread blocks, so as to reduce the uneven lateral force distribution during cornering and the irregular wear of the tire.

[0048] In this embodiment, the width ratio of all shoulder pattern blocks to the middle pattern block is the same. It should be noted that the width ratio of each shoulder pattern block to the middle pattern block may also be different.

[0049] It should be noted that the width ratio between the shoulder pattern block and the middle pattern block is not limited to this value and can be adjusted according to working conditions and usage requirements. Optionally, the width ratio between the shoulder pattern block and the middle pattern block can be 1.38, 1.40, 1.42, 1.48, 1.50, or 1.52.

[0050] Optionally, the tire tread structure further includes a first groove 60, which is disposed on the first tread block 31 to connect the first groove 11 and the second groove 12; and / or, the first groove 60 is disposed on the second tread block 32 and communicates with the second groove 12; and / or, the first groove 60 is disposed on the third tread block 33 and communicates with the first groove 11. In this way, the above-mentioned arrangement of the first groove 60 forms a multi-dimensional drainage network, further enhancing the tire surface's ability to puncture the water film, effectively reducing dynamic water pressure, increasing the critical hydroplaning speed, and enhancing the grip and braking performance on wet and slippery surfaces. Furthermore, this arrangement allows for more flexible placement of the first groove 60 to meet different usage needs and working conditions, and also improves the processing flexibility of the workers.

[0051] In this embodiment, the first tread block 31, the second tread block 32 and the third tread block 33 are all provided with a first groove 60 to form a multi-dimensional drainage network on the central tread block, further improving the tire surface's ability to puncture the water film, effectively reducing dynamic water pressure, increasing the critical hydroplaning speed, and enhancing the grip and braking performance on wet and slippery surfaces.

[0052] like Figure 1 As shown, the neutral surface S of the first groove 60 is inclined relative to the first groove 11 at an angle β. The first groove 60 includes a plurality of first sub-groove groups 61 and a plurality of second sub-groove groups 62. Adjacent first sub-groove groups 61 are connected by at least one second sub-groove group 62, and adjacent second sub-groove groups 62 are connected by at least one first sub-groove group 61. This arrangement of the first groove 60 effectively reduces tire rolling noise, enhances tire drainage capacity, increases critical hydroplaning speed, and improves grip and braking performance on wet surfaces.

[0053] like Figure 3 As shown, each first sub-groove group 61 includes a first groove segment 611, a second groove segment 612, and a third groove segment 613 connected in sequence. The first groove segment 611 and the second groove segment 612 are arranged at a first angle, and the second groove segment 612 and the third groove segment 613 are arranged at a second angle. The first groove segment 611 and the third groove segment 613 are located on the same side of the second groove segment 612. In this way, the above arrangement makes the first sub-groove group 61 a complex-oriented tortuous groove: while increasing the groove area for the tire to cut the water film at ground contact, its complex orientation can disperse the vibration energy generated by the tire during rolling, reduce noise, and improve the low-noise performance of the tire.

[0054] like Figure 3 As shown, each second sub-groove group 62 includes a fourth groove segment 621, a fifth groove segment 622, and a sixth groove segment 623 connected in sequence. The fourth groove segment 621 and the fifth groove segment 622 are arranged at a third angle, and the fifth groove segment 622 and the sixth groove segment 623 are arranged at a fourth angle. The fourth groove segment 621 and the sixth groove segment 623 are located on the same side of the fifth groove segment 622. The second groove segment 612 of each first sub-groove group 61 is located on one side of the neutral plane S, and the fifth groove segment 622 of each second sub-groove group 62 is located on the other side of the neutral plane S. In this way, the above arrangement makes the second sub-groove group 62 a complex-oriented tortuous groove: while increasing the groove area for the tire to cut the water film at ground contact, its complex orientation can disperse the vibration energy generated by the tire during rolling, reduce noise, and improve the low-noise performance of the tire.

[0055] Optionally, the ratio of the length x1 of the orthographic projection of the first groove segment 611 on the neutral plane S, the length y1 of the orthographic projection of the second groove segment 612 on the neutral plane S, and the length z1 of the orthographic projection of the third groove segment 613 on the neutral plane S is 1:a:b; and satisfies 1.1≤a≤1.5, 1.7≤b≤2.5; and / or, the ratio of the length x2 of the orthographic projection of the fourth groove segment 621 on the neutral plane S, the length y2 of the orthographic projection of the fifth groove segment 622 on the neutral plane S, and the length z2 of the orthographic projection of the sixth groove segment 623 on the neutral plane S is 1:a':b'; and satisfies 1.1≤a'≤1.5, 1.7≤b'≤2.5. In this way, the above arrangement can effectively increase the groove area for cutting the water film when the tire contacts the ground. Simultaneously, the complex structure of the tread pattern can disperse the vibration energy generated by the tire during rolling, reducing the propagation of vibration to the surrounding environment. This dispersion effect helps to reduce low-frequency noise caused by tire vibration.

[0056] In this embodiment, a is 1.3, b is 2, and a' is 1.3 and b' is 2.

[0057] It should be noted that the value of 'a' is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, 'a' can be 1.2 or 1.4.

[0058] It should be noted that the value of b is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, b can be 1.8, 1.9, 2.1, 2.2, 2.3, or 2.4.

[0059] It should be noted that the value of a' is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, a' can be 1.2 or 1.4.

[0060] It should be noted that the value of b' is not limited to this and can be adjusted according to the working conditions and usage requirements. Optionally, b' can be 1.8, 1.9, 2.1, 2.2, 2.3, or 2.4.

[0061] Optionally, the tire tread structure further includes a second groove 70, which is disposed on the first tread block 31 to connect the first groove 11 and the second groove 12; and / or, the second groove 70 is disposed on the second tread block 32 to connect the second groove 12 and the third groove 13; and / or, the second groove 70 is disposed on the third tread block 33 to connect the first groove 11 and the third groove 13; and / or, the second groove 70 is disposed on the fourth tread block 34 and communicates with the third groove 13. In this way, the above-mentioned arrangement of the second groove 70 can further enhance the tire's water drainage performance. Simultaneously, by optimizing the tire's ground pressure distribution through the layout of the second groove 70, hydroplaning can be effectively reduced, improving driving safety. Furthermore, the complex lateral second grooves 70 in the tire crown tread block area enhance the tire's ability to puncture a water film. Since the second groove 70 is connected to the first groove 11, the second groove 12, and the third groove 13, a multi-dimensional drainage network is formed, further improving drainage efficiency.

[0062] In this embodiment, the first tread block 31, the second tread block 32, the third tread block 33, and the fourth tread block 34 are all provided with second grooves 70 to enhance the tire's wet grip capability. By optimizing the orientation and shape of the second grooves 70, while ensuring wet grip capability, the pumping noise and resonance noise caused by unreasonable tread design in traditional tires during driving are reduced, thus reducing noise pollution during tire operation and improving driving and riding comfort. Simultaneously, the second grooves 70 are connected to the first grooves 11, the second grooves 12, and the third grooves 13 to form a multi-dimensional drainage network, further enhancing the tire's ability to puncture the water film on the tire surface, effectively reducing dynamic water pressure, increasing the critical hydroplaning speed, and enhancing grip and braking performance on wet surfaces.

[0063] Optionally, the neutral surface S' of the second groove 70 is inclined relative to the first groove 11 at an angle α, where the angle α and angle β satisfy: 3°≤(α-β)≤5°; or, 3°≤(β-α)≤5°. This angle difference reduces the resonance of air within each groove during driving, dispersing the vibration energy of the tire during operation.

[0064] like Figure 2As shown, the inner surface of the second groove 70 includes a first plane 71, an arcuate surface 72, a second plane 73, and an inclined surface 74. The first plane 71 is connected to the second plane 73 via the arcuate surface 72, and the inclined surface 74 is connected to the second plane 73 and is set at an obtuse angle to the second plane 73. The first plane 71 is positioned opposite to the second plane 73 and the inclined surface 74. This arrangement makes the second groove 70 a groove with a gradually changing depth, thereby ensuring wet skidding and drainage capabilities while reducing noise caused by abrupt changes in groove depth, thus improving the tire's low-noise performance.

[0065] This application also provides a tire (not shown) including the tire tread structure described above.

[0066] Optionally, the tires are used for commercial vehicles.

[0067] In this embodiment, the above-mentioned tire configuration can solve the problems of insufficient grip, severe uneven wear, and high noise of commercial vehicle tires on wet and slippery roads.

[0068] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0069] The tire tread structure includes at least two grooves, at least two tread blocks, and a set of sheet-like structures. At least two grooves are spaced apart along the tire's central axis, each groove extending circumferentially; the ratio of the width w of each groove to the width W of the tire's running surface is greater than or equal to 0.055 and less than or equal to 0.06. At least two tread blocks are spaced apart along the tire's central axis, with at least one groove between adjacent tread blocks and at least one tread block between adjacent grooves. The set of sheet-like structures is disposed on at least one tread block near the tire shoulder; and / or, the set of sheet-like structures is disposed on the groove wall of at least one groove near the tire shoulder; wherein the set of sheet-like structures includes multiple sheet-like structures spaced apart circumferentially along the tire. This arrangement of at least two grooves ensures sufficient water storage space on wet surfaces, increasing the water storage and drainage capacity per unit time during rapid tire rolling, effectively removing accumulated water, reducing the water film effect, and thus solving the problem of insufficient drainage capacity and significant water film effect in existing tires on wet surfaces, which affects driving safety. Meanwhile, the grooves and sheet-like structures increase the roughness of the tire surface, improving the tire's grip on wet and slippery roads, thereby enhancing driving safety.
