Description

Technical Field

[0001] This utility model relates to tire tread patterns, and more particularly to a tire tread pattern suitable for all wheel positions on mixed road surfaces. Background Technology

[0002] As people's living standards and technological levels improve, customers have increasingly higher requirements for tire performance on various road conditions and wheel positions. They not only demand that tires be able to operate on asphalt roads but also adapt to gravel and sandy conditions. This places higher demands on tire traction and steering, as well as heat dissipation, rolling resistance, and stone removal capabilities.

[0003] CN113650456A provides a comprehensive road tire tread pattern structure and tire, with two middle rows of tread blocks, two sides of tread strips, and a closed shoulder, resulting in poor heat dissipation of the tire; moreover, the sipes are inclined vertical sipes, leading to poor stability of the tread blocks. Utility Model Content

[0004] To address the aforementioned problems, this invention provides an all-wheel tire tread pattern suitable for mixed road surfaces. The longitudinal tread grooves are either zigzag or S-shaped, increasing tire guidance and grip, and providing enhanced driving performance. The bending angle of the sipes is equal to that of adjacent longitudinal tread grooves, allowing stress to be dispersed through the deformation of the sipes when the tread blocks are under load. This increases the overall integrity of the tire design, enhances tread block stability, and further reduces the risk of tread block breakage. Transverse grooves are formed between adjacent tread blocks arranged in the same circumferential direction, increasing the tire's heat dissipation.

[0005] The technical solution of this utility model is as follows:

Detailed Implementation

[0024] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. It should be understood that the preferred embodiments described herein are only for illustration and explanation of this utility model and should not be construed as limiting the scope of protection of this utility model. Those skilled in the art can make some non-essential improvements and adjustments based on the content of this utility model below. In this utility model, unless otherwise expressly specified and limited, the technical terms used in this application should have the ordinary meaning understood by those skilled in the art.

[0025] like Figure 1 As shown, a tire tread pattern suitable for mixed road surfaces includes a tread pattern, which includes tread blocks 2 arranged along the tire circumference and longitudinal tread grooves 1 arranged along the tire circumference. The longitudinal tread grooves are either zigzag grooves or S-shaped grooves. The tread blocks are provided with sipes 3, which are L-shaped sipes. The bending angle of the L-shaped sipes is equal to the bending angle of the adjacent longitudinal tread grooves. Transverse grooves are formed between adjacent tread blocks 2 arranged in the same circumference.

[0026] The L-shaped cutter groove includes cutter groove I 30 and cutter groove II 31. One end of cutter groove I 30 is connected to one end of cutter groove II 31. The included angle between cutter groove I and cutter groove II is the bending angle of the L-shaped cutter groove.

[0027] Longitudinal tread grooves, whether zigzag or S-shaped, enhance tire guidance and grip, providing stronger driving performance. The bending angle of the sipes is equal to that of adjacent longitudinal tread grooves, allowing stress to be dispersed through the deformation of the sipes when the tread blocks are under load. This increases the overall integrity of the tire design, enhances tread block stability, and further reduces the risk of tread block breakage. Lateral grooves are formed between adjacent tread blocks 2 arranged in the same circumferential direction, increasing tire heat dissipation.

[0028] The longitudinal tread groove 1 includes a central tread groove 4 and an intermediate tread groove 5, and the tread block 2 includes an intermediate tread block 6 and an edge tread block 7; the tread pattern from the center to both sides includes a central tread groove, an intermediate tread block, an intermediate tread groove, and an edge tread block, respectively.

[0029] The groove on the middle patterned block has two adjacent longitudinal grooves, and the bending angle of the groove is equal to the bending angle of the adjacent longitudinal grooves on both sides.

[0030] The middle patterned block 6 forms a longitudinal patterned groove on one side, including side I 60 and side II 61, with one end of side I 60 connected to one end of side II 61. The other side includes side III 62 and side IV 63, with one end of side III 62 connected to one end of side IV 63. The angle between side I 60 and side II 61, and the angle between side III 62 and side IV 63, respectively form the bending angles of the patterned groove. The bending angle a of the patterned groove formed between side I 60 and side II 61 of the same patterned block is less than 180°, while the bending angle b of the patterned groove formed between side I 60 and side II 61 of adjacent patterned blocks is greater than 180°. The bending angle c of the patterned groove formed between side III 62 and side IV 63 of the same patterned block is greater than 180°, while the bending angle d of the patterned groove formed between side III 62 and side IV 63 of adjacent patterned blocks is less than 180°.

[0031] The edge of the patterned block 7 forming the middle patterned groove includes edge V70 and edge VI71 connected at the end. The bending angle e of the patterned groove formed between edge V70 and edge VI71 of the same patterned block is less than 180°, and the bending angle f of the patterned groove formed between edge V70 and edge VI71 of adjacent patterned blocks is greater than 180°.

[0032] The middle patterned block 6 is at least hexagonal, and the edge patterned blocks 7 are at least pentagonal. By using polygonal designs for the patterned blocks and rounding the corners to avoid sharp edges, the patterned blocks are prevented from breaking and are made more integrated. This effectively disperses stress, making the patterned blocks more evenly stressed and reducing the risk of them falling off.

[0033] The bending angle of the longitudinal tread grooves is 120°-140°. The deformation and stress of the tread blocks are more uniform, making the tire more wear-resistant, with stronger grip and better handling stability.

[0034] The central tread groove 4 is mirrored to form the intermediate tread groove 5. The symmetrical arrangement of the longitudinal tread grooves not only improves the tire's appearance but also ensures even stress distribution and reduces wear.

[0035] The three longitudinal tread grooves are of equal width and depth. This optimizes the tire's water drainage, traction, and mileage.

[0036] The tread blocks 2 arranged in the same circumference are connected by reinforcing ribs 8; the intermediate tread blocks 6 arranged in the same circumference are connected by first reinforcing ribs 80, and the edges of the intermediate tread blocks 6 connected to the first reinforcing ribs 80 are perpendicular to the first reinforcing ribs 80; the edge tread blocks 7 arranged in the same circumference are connected by second reinforcing ribs 81, and the second reinforcing ribs 81 are perpendicular to the tire width direction.

[0037] The edge of the intermediate pattern block 6 connected to the first reinforcing rib 80 is inclined, and there is an angle g between this edge and the tire width direction, the angle g being 10°-30°.

[0038] Stone-laying platforms 9 are evenly arranged in the longitudinal patterned groove 1. Adjacent stone-laying platforms 9 are connected by a third reinforcing rib 82. The stone-laying platforms bend along with the longitudinal patterned groove.

[0039] The stone-discharging platform 9 includes a rectangular stone-discharging platform I 90 and a bent stone-discharging platform II 91. These enhance stone-discharging performance and resistance to punctures.

[0040] The width of the stone-laying platform 9 is 5-7mm, and the thickness is 2.5-3.5mm. The stone-laying platform is designed with fixed dimensions, such as a width of 6mm and a thickness of 3mm. This ensures uniform stress distribution at the bottom of the trench, effectively reducing stress concentration and preventing cracks.

[0041] The two intermediate tread grooves 5 on both sides of the tread pattern are staggered along the tire circumference, and the staggered length is 23-27mm.

[0042] A second transverse groove 10 is formed between adjacent edge tread blocks 7 arranged in the same circumference. The second transverse groove 10 extends to the tire shoulder and the other end connects with the middle tread groove.

[0043] The second lateral groove 10 extends to the tire shoulder, thus forming an open shoulder groove. The open shoulder groove design increases the tire's heat dissipation and traction, making it suitable for mixed road surfaces.

[0044] A first lateral groove 11 is formed between adjacent intermediate tread blocks 6 arranged in the same circumference. The first lateral groove 11 has the same depth as the longitudinal tread grooves on both sides. This enhances the tire's grip and heat dissipation.

[0045] The first lateral groove 11 and the second lateral groove 10 have the same inclination angle. This creates a more efficient snow and mud removal channel, improving the tire's performance on snow and mud.

[0046] The tread pattern is symmetrical.

[0047] In summary, to address the shortcomings of current tread patterns in complex road conditions, the design of longitudinal tread grooves enhances tire guidance, traction, and heat dissipation. The consistent inclination angles of the first and second lateral grooves create more efficient snow and mud removal channels, improving tire performance on snow and mud. The tread blocks employ a polygonal design with rounded or curved edges to prevent sharp corners, ensuring the blocks remain intact and more integrated. This effectively distributes stress, resulting in more even force distribution and preventing block breakage. The bending angle of the sipes is equal to that of adjacent longitudinal tread grooves, allowing stress to be dispersed through deformation of the sipes when the tread blocks are under load. This increases the overall integrity of the tire design, enhances tread block rigidity, and thus improves tread block stability, further reducing the risk of block breakage. The spaced stone-removing platforms enhance the tire's stone removal and puncture resistance. Designed with fixed dimensions, these platforms ensure even stress distribution at the bottom of the grooves, effectively reducing stress concentration and preventing cracking. The tread pattern adopts an integral design, which can easily disperse stress, making the entire tire more evenly stressed, reducing stress concentration, reducing the risk of tread block breakage, and preventing groove bottom cracking.
