[0021] To address the problem that existing tires cannot simultaneously achieve both comfort and handling, this application provides a tire.

[0022] like Figure 1 As shown, the tire tread has a tread pattern, which includes lateral grooves 10, reinforcing components 30, and connecting structures 40. The lateral grooves 10 extend along the width of the tire, and there are multiple lateral grooves 10. These multiple lateral grooves 10 are spaced apart circumferentially to divide the tire tread into multiple tread units 20. At least some of the lateral grooves 10 are arranged in a zigzag pattern. The reinforcing components 30 are disposed on the bottom wall of the lateral grooves 10 and protrude from the bottom wall of the lateral grooves 10. The reinforcing components 30 include multiple reinforcing protrusions 31, which are spaced apart along the extending direction of the lateral grooves 10. The connecting structures 40 are disposed on the bottom wall of at least one lateral groove 10 and located between two adjacent reinforcing protrusions 31. The two ends of the connecting structures 40 are respectively connected to two adjacent tread units 20.

[0023] Using the technical solution of this embodiment, the tire tread is provided with a tread structure. The lateral grooves 10 of the tread structure extend along the width direction of the tire. There are multiple lateral grooves 10, which are spaced apart circumferentially along the tire to divide the tire tread into multiple tread units 20. At least some of the lateral grooves 10 are arranged in a zigzag shape. A reinforcing component 30 is disposed on the bottom wall of the lateral groove 10 and protrudes from the bottom wall of the lateral groove 10. The reinforcing component 30 includes multiple reinforcing protrusions 31, which are spaced apart along the extending direction of the lateral groove 10. A connecting structure 40 is disposed on the bottom wall of at least one lateral groove 10 and located between two adjacent reinforcing protrusions 31. The two ends of the connecting structure 40 are respectively connected to two adjacent tread units 20. In this way, when the mining wide-body dump truck travels on complex road surfaces, the multiple lateral grooves 10 ensure tire grip, traction, and handling. Furthermore, they effectively drain water and mud from between the tire and the road surface, ensuring self-cleaning while also providing ventilation and heat dissipation. Simultaneously, the reinforcing component 30, through multiple reinforcing protrusions 31, pushes out stones that enter the lateral grooves 10, preventing them from cutting the grooves and ensuring tire wear resistance and cut resistance, thus extending tire lifespan. Furthermore, the connecting structure 40 connects two tread units 20, enhancing the rigidity of the tire tread blocks, ensuring tire handling and traction, and preventing tread block detachment. This further enhances tire wear resistance and cut resistance, extending tire lifespan and thus solving the problem of short tire lifespan in existing mining wide-body dump trucks.

[0024] like Figure 1 As shown, in two adjacent lateral grooves 10, a connecting structure 40 is disposed on the bottom wall of one of the lateral grooves 10. At least three reinforcing protrusions 31 are located on one side of the connecting structure 40. This arrangement ensures that one of the two adjacent lateral grooves 10 has a connecting structure 40, allowing the connecting structures 40 to be alternately disposed within the lateral grooves 10. This balances the rigidity of the tread blocks in the tire shoulder tread area, ensuring grip and handling in the tire shoulder tread area. Furthermore, the connecting structure 40 is located between the third and fourth reinforcing protrusions 31, making its placement more suitable. This also allows the connecting structure 40, together with the reinforcing protrusions 31, to push out stones encountered during driving, preventing stones from cutting the bottom wall of the lateral groove 10, protecting the tire tread groove bottom, preventing tread groove bottom cutting and tread thread leakage, improving tire wear resistance, and extending tire life.

[0025] like Figure 1As shown, there are multiple reinforcing components 30, which are spaced apart along the extension direction of the transverse groove 10. The height H1 of the reinforcing protrusion 31 satisfies the condition: 8mm ≤ H1 ≤ 12mm. This allows the multiple reinforcing components 30 to increase the area of ​​the reinforcing components 30 on the bottom wall of the transverse groove 10, thereby increasing the area where the reinforcing protrusion 31 pushes out stones, improving the tire's stone removal performance and wear resistance. Simultaneously, the height setting of the reinforcing protrusion 31 ensures that it not only effectively pushes out most stones stuck in the transverse groove 10, but also that the reinforcing protrusion 31 itself has sufficient structural strength to prevent root tearing or damage due to excessive height, further improving tire wear resistance.

[0026] In this embodiment, the height H1 of the reinforcing protrusion 31 satisfies: H1=10mm, so that the height of the reinforcing protrusion 31 is more appropriate.

[0027] In this embodiment, two reinforcing components 30 are provided, and the two reinforcing components 30 are disposed opposite to each other on the bottom wall of the transverse groove 10.

[0028] It should be noted that the number of enhancement components 30 is not limited to this and can be adjusted according to working conditions and usage requirements. Optionally, the number of enhancement components 30 can be three, five, six, or more.

[0029] In this embodiment, in two adjacent transverse grooves 10, the reinforcing component 30 in one transverse groove 10 has 12 reinforcing protrusions 31, and the reinforcing component 30 in the other transverse groove 10 has 13 reinforcing protrusions 31. A connecting structure 40 is provided between the third reinforcing protrusion 31 and the fourth reinforcing protrusion 31 with 12 reinforcing protrusions 31.

[0030] like Figure 1 As shown, the tread structure also includes longitudinal grooves 50. Each tread unit 20 has multiple longitudinal grooves 50, with each end of the longitudinal groove 50 connected to two adjacent transverse grooves 10. The longitudinal grooves 50 of each tread unit 20 are spaced apart along the width of the tire to divide each tread unit 20 into multiple tread blocks. The depth of the longitudinal grooves 50 is less than the thickness of the tread unit 20, and the bottom wall of the longitudinal groove 50 connects to two adjacent tread blocks. In this way, the longitudinal grooves 50 can connect to adjacent transverse grooves 10, assisting in the drainage of accumulated water and mud from the tread, improving the tire's self-cleaning performance. Simultaneously, the longitudinal grooves 50 connect two adjacent tread blocks, ensuring the rigidity of the tread blocks and further guaranteeing the tire's traction and handling.

[0031] In this embodiment, the depth direction of the longitudinal groove 50 is consistent with the direction perpendicular to the tire tread.

[0032] like Figure 1 As shown, the tread pattern also includes a first raised structure 60. The first raised structure 60 is disposed on the bottom wall of the lateral groove 10 and located on the side of the reinforcing component 30 near the tire shoulder. The first raised structure 60 is connected to two adjacent tread units 20. The height H2 of the first raised structure 60 satisfies: 31mm ≤ H2 ≤ 35mm. In this way, the first raised structure 60 can reduce the contact depth of the tread block edge, effectively improving the rigidity of the tread block at the tire shoulder, ensuring the tire's handling during cornering, and also enhancing the root rigidity of the tread block most susceptible to side impacts from gravel, avoiding the risk of cutting and chipping of the shoulder tread block 21, and improving the tire's wear resistance.

[0033] In this embodiment, the first protrusion structure 60 is made of cut-resistant rubber to help reduce cutting at the tire shoulder or reduce the extension of cracks caused by driving, thereby further improving the tire's wear resistance and extending its service life.

[0034] In this embodiment, the height H2 of the first protrusion structure 60 satisfies: H2=33mm, so as to ensure that the value of the height H2 of the first protrusion structure 60 is appropriate.

[0035] like Figure 1 As shown, the multiple tread blocks include two shoulder tread blocks 21 and multiple intermediate tread blocks 22 located between the two shoulder tread blocks 21. Each intermediate tread block 22 has a first heat dissipation groove 23, which is polygonal in shape. The groove depth D1 of the first heat dissipation groove 23 satisfies the condition: 20mm ≤ D1 ≤ 40mm. Thus, by providing the polygonal first heat dissipation groove 23 on the intermediate tread blocks 22, which bear the main load, the heat dissipation surface area of ​​the tread is significantly increased, improving the tire's heat dissipation performance. Simultaneously, the polygonal design of the first heat dissipation groove 23 provides good ductility, ensuring the tire's ductility requirements during driving and improving its adaptability. Furthermore, the groove depth of the first heat dissipation groove 23 ensures sufficient airflow space, efficiently dissipating heat from the interior of the tread blocks, effectively reducing the rate of rubber thermal aging, preventing rubber degradation and tread delamination caused by high temperatures, and further extending the tire's service life.

[0036] In this embodiment, the first heat dissipation groove 23 is in the shape of a parallelogram, with the four sides of the parallelogram and the side edges of the corresponding patterned block arranged in parallel.

[0037] In this embodiment, the groove depth D1 of the first heat dissipation groove 23 satisfies: D1=30mm, so as to increase the heat dissipation area of ​​the tire by 18% and the tread area of ​​the tire by 21%.

[0038] like Figure 1 As shown, the intermediate tread blocks 22 include an inner intermediate tread block 221 located on the inner side of the tire and an outer intermediate tread block 222 located on the outer side of the tire. The tread structure also includes a second protrusion structure 70. The second protrusion structure 70 is disposed on the bottom wall of the lateral groove 10 and protrudes from the bottom wall of the lateral groove 10. In two adjacent tread units 20, one end of the second protrusion structure 70 is connected to the inner intermediate tread block 221 of one of the tread units 20, and the other end of the second protrusion structure 70 is connected to the outer intermediate tread block 222 of the other tread unit 20. In this way, the second protrusion structure 70 connects the inner and outer tread blocks of two adjacent tread units 20 in a similar cross-shaped manner, forming a stable rigid support frame inside the tread, further consolidating the anti-deformation ability of the tire tread blocks, balancing the ground pressure between the inner and outer sides of the tire, improving the driving stability of the vehicle in cornering or complex road conditions, and improving the tire's safety and handling.

[0039] like Figure 1 As shown, the lateral groove 10 includes a first sub-lateral groove 11 and at least two second sub-lateral grooves 12. The first sub-lateral groove 11 is arranged in a zigzag shape. The at least two second sub-lateral grooves 12 are respectively connected to the opposite ends of the first sub-lateral groove 11. The end of the second sub-lateral groove 12 away from the first sub-lateral groove 11 is connected to the tire shoulder. The second sub-lateral groove 12 is arranged at an angle A with the width direction of the tire, and the angle A satisfies: 11°≤A≤15°; and / or, the width of the second sub-lateral groove 12 gradually increases along the direction from the tread to the tire shoulder; and / or, wherein the reinforcing component 30 is disposed on the bottom wall of the first sub-lateral groove 11. In this way, the lateral groove 10 achieves a zigzag shape through the first sub-lateral groove 11, enabling the tire to generate multi-angle scraping and digging effects when touching the ground through the edge of the zigzag first lateral groove 10, greatly improving the tire's mud removal efficiency and self-cleaning ability in soft mud. Meanwhile, the lateral groove 10 gradually expands its width through the second sub-lateral groove 12, providing a smooth escape channel for the discharged mud and gravel, preventing mud and gravel from clogging the tire shoulder, improving the tire's mud discharge efficiency, preventing the tire from slipping due to mud, and improving the tire's traction.

[0040] In this embodiment, the included angle A satisfies: A=13°, to ensure that the value of the included angle A is more appropriate.

[0041] In this embodiment, the first sub-lateral groove 11 is arranged in a zigzag shape, and combined with the longitudinal groove 50, the middle tread block 22 is divided into a hexagon, and the shoulder tread block 21 is divided into a pentagon, which ensures the grip and handling of the tire tread blocks.

[0042] like Figure 1 As shown, a second heat dissipation groove 80 is provided on the tire sidewall. One end of the second heat dissipation groove 80 is connected to the lateral groove 10, and at least a portion of the other end of the second heat dissipation groove 80 is arc-shaped and spaced apart from the edge of the tire sidewall. The groove depth D2 of the second heat dissipation groove 80 satisfies the condition: 3mm ≤ D2 ≤ 7mm. This arrangement of the second heat dissipation groove 80 increases the heat dissipation area at the tire shoulder and sidewall, further improving the tire's heat dissipation performance. Simultaneously, the arc-shaped end of the second heat dissipation groove 80 effectively eliminates stress concentration, preventing cracks from forming at the end of the second heat dissipation groove 80 during tire sidewall flexing, thus improving the durability of the tire sidewall. Furthermore, the groove depth of the second heat dissipation groove 80 ensures both tire sidewall rigidity and sufficient airflow space, efficiently dissipating heat from the inside of the tire sidewall, effectively reducing the rate of rubber thermal aging, avoiding rubber degradation and crown voids caused by high temperatures, and further extending the tire's service life.

[0043] In this embodiment, the groove depth D2 of the second heat dissipation groove 80 satisfies: D2=5mm, so as to increase the heat dissipation area of ​​the tire sidewall and increase the tire sidewall area by 15%.

[0044] like Figure 1 As shown, there are multiple second heat dissipation grooves 80, which are spaced apart along the circumference of the tire. A third heat dissipation groove 90 is provided on the tire sidewall, positioned between adjacent second heat dissipation grooves 80. The third heat dissipation groove 90 is polygonal in shape, with at least one apex angle featuring a curved transition. This arrangement of the third heat dissipation groove 90 with the second heat dissipation grooves 80, and their interaction, further increases the heat dissipation area on the tire sidewall, improving its heat dissipation performance and thus the overall tire heat dissipation performance. Simultaneously, the polygonal design with rounded corners of the third heat dissipation groove 90 balances heat dissipation and crack prevention, enhancing both tire durability and heat dissipation.

[0045] In this embodiment, the third heat dissipation groove 90 is arranged in a quadrilateral shape, and the four vertices of the quadrilateral are all rounded.

[0046] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects: The tire tread has a tread pattern with lateral grooves extending along the width of the tire. Multiple lateral grooves are spaced apart circumferentially to divide the tread into multiple tread units, with at least some grooves arranged in a zigzag pattern. Reinforcing components are disposed on and protrude from the bottom wall of the lateral grooves. These reinforcing components include multiple reinforcing protrusions spaced apart along the extension direction of the lateral grooves. A connecting structure is disposed on the bottom wall of at least one lateral groove, located between two adjacent reinforcing protrusions, with both ends connected to two adjacent tread units. Thus, when the mining wide-body dump truck travels on complex road surfaces, the multiple lateral grooves ensure tire grip, traction, and handling. Furthermore, they allow water and mud to drain from between the tire and the road surface, ensuring self-cleaning performance, while also providing ventilation and heat dissipation. Meanwhile, the reinforcing components, through multiple reinforcing protrusions, can push out stones that enter the lateral grooves, preventing the stones from cutting into the grooves, ensuring the tire's wear resistance and cut resistance, and extending its service life. Simultaneously, the connection structure connects two tread units, enhancing the rigidity of the tire tread blocks, ensuring tire handling and traction, and preventing the risk of tread block detachment, further guaranteeing the tire's wear resistance and cut resistance, and further extending its service life. This solves the problem of short service life in existing mining wide-body dump truck tires.
