Description

Technical Field

[0001] This utility model relates to the field of automobile tire technology, and in particular to an SUV tire suitable for winter use. Background Technology

[0002] With the development of the automotive industry, the demand for SUVs has increased significantly, and the market capacity is growing, making them very popular. In northern regions like Northern Europe and high-latitude areas, winters are cold and snowy with long periods of snow. For vehicles used as transportation, winter safety is significantly reduced. Therefore, to ensure safety, SUVs must be fitted with snow tires before winter to adapt to driving on cold, icy roads and maintain excellent grip and traction. Using snow tires also eliminates the need for snow chains, reducing vehicle fuel consumption and road surface damage.

[0003] As the number of SUVs continues to increase, the demand for matching tires is also increasing. Existing winter-suitable snow tires for SUVs have poor performance, resulting in poor grip, slippage, and traction on icy and snowy roads.

[0004] Therefore, this application provides an SUV tire suitable for winter that has strong grip on icy and snowy roads, is not easy to slip, and has good traction, in order to solve the problems of poor grip, easy slippage, and poor traction of existing SUV tires suitable for winter on icy and snowy roads. Summary of the Invention

[0005] This application provides an SUV tire suitable for winter use that has strong grip on icy and snowy roads, is not prone to slipping, and has good traction, in order to solve the problems of poor grip, easy slipping, and poor traction of existing SUV tires suitable for winter use on icy and snowy roads.

[0006] Specifically, an SUV tire suitable for winter includes a central tread and shoulder treads connected to both sides of the central tread. The central tread is provided with an annular straight groove 1, an annular curved groove 1, an annular curved groove 2, and an annular straight groove 2 in sequence. The annular straight groove 1 and annular curved groove 1 are symmetrical with the annular straight groove 2 and annular curved groove 2 about the annular center line of the central tread. Between the annular straight groove 1 and annular curved groove 1, there are continuous block patterns 1 and 2. Between the annular curved groove 1 and annular curved groove 2, there are continuous block patterns 3 and 4. Between the annular curved groove 2 and annular straight groove 2, there are continuous block patterns 5 and 6. Block patterns 1, 2, and 3 are respectively symmetrical with block patterns 6, 5, and 4 about the center between block patterns 3 and 4. Curved grooves are also provided between block patterns 3 and 4.

[0007] Furthermore, the block pattern one, block pattern two, block pattern three, block pattern four, block pattern five, and block pattern six are all polygonal block patterns.

[0008] Furthermore, the shoulder tread is also provided with an annular straight groove three, and a continuous block pattern seven is provided between one side of the annular straight groove three and the annular straight groove one of the central tread, and a continuous block pattern eight is provided on the other side of the annular straight groove three, and the block pattern seven and the block pattern eight are staggered.

[0009] Furthermore, each of the block pattern three and block pattern four has a plurality of horizontal pattern blocks, and each of the block pattern one, block pattern two, block pattern five, and block pattern six has a plurality of oblique pattern blocks. The plurality of horizontal pattern blocks in block pattern three and the plurality of horizontal pattern blocks in block pattern four are centrally symmetrical about the center between block pattern three and block pattern four. The plurality of oblique pattern blocks in block pattern one and the plurality of oblique pattern blocks in block pattern six are centrally symmetrical about the center between block pattern three and block pattern four. The plurality of oblique pattern blocks in block pattern two and the plurality of oblique pattern blocks in block pattern six are centrally symmetrical about the center between block pattern three and block pattern four.

[0010] Furthermore, horizontal pattern grooves are provided between several horizontal pattern blocks respectively provided on block pattern three and block pattern four, and oblique pattern grooves are provided between several oblique pattern blocks respectively provided on block pattern one, block pattern two, block pattern five and block pattern six. Some of the horizontal pattern grooves are curved pattern grooves, and some of the oblique pattern grooves are curved pattern grooves.

[0011] Furthermore, each of the block pattern one, block pattern two, block pattern three, block pattern four, block pattern five, and block pattern six is ​​provided with serrated 3D fine steel strips, which are interlocked and arranged in an alternating manner.

[0012] Furthermore, the sharp corners of all six block patterns are chamfered.

[0013] The technical solution provided in this application has at least the following beneficial effects: the SUV tire suitable for winter provided in this application has two annular curved grooves in the middle and annular straight grooves on both sides, and continuous block patterns between the grooves, which effectively improves the straightness of the road surface on ice and snow in winter, ensures high grip in winter, and improves safety.

[0014] The blocky, polygonal design improves the vehicle's ability to navigate complex road surfaces in winter.

[0015] The symmetrical and interlocking design of the block pattern three and block pattern four effectively provides forward grip and traction, making it more robust and stable on icy and snowy roads.

[0016] The symmetrical arrangement of lateral tread blocks and the centrally symmetrical arrangement of oblique tread blocks on the block-shaped tread blocks, along with the corresponding lateral and oblique tread grooves, allows the tire to be installed in both directions, facilitating future replacement and extending its service life.

[0017] The curved tread grooves in certain areas increase the tire's ability to drain water and expel ice and snow, strengthen the grip between the tire and the ground, improve traction and passability, and ensure safety.

[0018] The tread grooves are formed by setting serrated 3D fine steel strips in the molding die, which improves the tire's grip on icy and snowy roads.

[0019] The chamfered design in the block pattern effectively captures snow into the curved grooves and pattern grooves and quickly discharges it, preventing slippage and improving snow traction performance.

[0020] The shoulder tread also features annular straight grooves three, with block patterns seven and eight staggered on both sides of the annular straight grooves three. This reduces shoulder rigidity, which can reduce tire noise and enhance grip performance on cold and icy roads. At the same time, after the shoulder tread rigidity is rebalanced, wear resistance can also be improved. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Please refer to Figures 1-3 This application provides a winter SUV tire 100, comprising a central tread 1 and shoulder treads 2 connected to both sides of the central tread 1. The central tread 1 is sequentially provided with annular straight groove 11, annular curved groove 12, annular curved groove 13, and annular straight groove 14. Annular straight groove 11, annular curved groove 12, annular straight groove 14, and annular curved groove 13 are symmetrical about the annular centerline of the central tread 1. Continuous block patterns 111 and 112 are provided between annular straight groove 11 and annular curved groove 12. Between the 2nd and the annular curved groove 13, there are continuous block patterns 313 and 414. Between the annular curved groove 13 and the annular straight groove 14, there are continuous block patterns 5115 and 616. Block patterns 111, 212, and 313 are respectively centrally symmetrical with block patterns 616, 5115, and 414 about the center between block patterns 313 and 414. A curved groove 117 is also provided between block patterns 313 and 414.

[0031] Specifically, the SUV tire 100 suitable for winter use provided in this application embodiment has four annular grooves: annular straight groove 11, annular curved groove 12, annular curved groove 2 13, and annular straight groove 2 14, and the four annular grooves are symmetrical about the annular center line. Continuous block patterns 111, 112, 113, 114, 115, and 116 are respectively provided between the annular grooves. This configuration effectively improves the straightness of the tire on icy and snowy roads in winter, minimizes noise generation, and makes the tread more able to grip the road surface, ensuring high grip under low-temperature conditions in winter and improving safety.

[0032] Furthermore, the block patterns 111, 112, 113, 114, 115, and 116 are all polygonal block patterns. The design of these block patterns improves the ability to traverse complex road surfaces in winter. It can be understood that these polygonal block patterns, placed between circular straight or curved ditches, can maximize grip, adapt to harsh environments such as mud, sand, snow, and gravel, meet the needs of different road surfaces, and also possess competitive climbing capabilities.

[0033] Block patterns 111, 212, and 313 are centrally symmetrical with block patterns 616, 515, and 414 about the center between block patterns 313 and 414, respectively. This can be understood as block patterns 111, 212, and 313 being reverse symmetrical with block patterns 616, 515, and 414.

[0034] Furthermore, a curved groove 117 is provided between block pattern three 113 and block pattern four 114, which can be understood as the polygonal shapes between block pattern three 113 and block pattern four 114 being interlocked. It can be understood that the centrally symmetrical and interlocking block patterns effectively provide forward grip and traction, providing stronger coverage on icy and snowy surfaces and better stability.

[0035] Furthermore, several horizontal pattern blocks 1141 are respectively provided on the block pattern three 113 and the block pattern four 114, and several oblique pattern blocks 1121 are respectively provided on the block pattern one 111, the block pattern two 112, the block pattern five 115, and the block pattern six 116. The several horizontal pattern blocks 1141 provided on the block pattern three 113 and the several horizontal pattern blocks 1141 provided on the block pattern four 114 are related to the block pattern three 113 and the block pattern four 114. The centers of the blocks are centrally symmetrical. The oblique pattern blocks 1121 set in the block pattern one 111 and the oblique pattern blocks 1121 set in the block pattern six 116 are centrally symmetrical about the center between the block pattern three 113 and the block pattern four 114. The oblique pattern blocks 1121 set in the block pattern two 112 and the oblique pattern blocks 1121 set in the block pattern six 116 are centrally symmetrical about the center between the center between the block pattern three 113 and the block pattern four 114.

[0036] This can be understood as the pattern blocks on pattern 111, pattern 212, and pattern 313 being centrally symmetrical with the pattern blocks on pattern 616, pattern 515, and pattern 414.

[0037] Furthermore, a horizontal pattern groove 1131 is provided between a plurality of horizontal pattern blocks 1141 respectively provided on the block pattern three 113 and the block pattern four 114, and an oblique pattern groove 1111 is provided between a plurality of oblique pattern blocks 1121 respectively provided on the block pattern one 111, the block pattern two 112, the block pattern five 115 and the block pattern six 116. A portion of the horizontal pattern groove 1131 is a curved pattern groove 1161, and a portion of the oblique pattern groove 1111 is a curved pattern groove 1161.

[0038] It is understandable that, based on the symmetry between several tread blocks of block pattern three 113 and several tread blocks of block pattern four 114, the transverse tread grooves 1131 between several tread blocks of block pattern three 113 and several tread blocks of block pattern four 114 are also centrally symmetrical. Clearly, the oblique tread grooves 1111 between block pattern one 111 and block pattern six 116, and between block pattern two 112 and block pattern five 115, are also centrally symmetrical. This design allows the tire to be installed and used in both directions, facilitating future replacement and extending its service life.

[0039] Furthermore, a portion of the lateral tread grooves 1131 is a curved tread groove 1161, and a portion of the oblique tread grooves 1111 are also curved tread grooves 1161. It should be noted that the curved tread grooves 1161 in certain positions increase the tire's water drainage and snow / ice removal capabilities, strengthen the tread's grip on the ground, enhance traction and passability, and ensure safety.

[0040] It is understandable that winter tires need to improve tread grip under cold conditions and soften tread rigidity. Therefore, when forming the tread grooves, serrated 3D fine steel strips are set in the forming mold to improve grip on icy and snowy roads.

[0041] Furthermore, the sharp corners of the block patterns 111, 112, 113, 114, 115, and 116 are all chamfered. Specifically, the chamfering design creates polygonal shapes, while the sharp corners without chamfering are beveled. This design effectively traps snow in the curved grooves 117 and the pattern grooves, allowing it to be quickly discharged, preventing slippage and improving snow traction.

[0042] Furthermore, the shoulder tread 2 is also provided with an annular straight groove 3 21. A continuous block pattern 7 22 is provided between one side of the annular straight groove 3 21 and the annular straight groove 11 of the center tread 1. A continuous block pattern 8 23 is provided on the other side of the annular straight groove 3 21. The block pattern 7 22 and the block pattern 8 23 are staggered.

[0043] Specifically, the staggered arrangement between block pattern 722 and block pattern 823 reduces shoulder rigidity, which can reduce tire noise, enhance grip performance on cold and icy roads, and improve wear resistance after the shoulder tread rigidity is rebalanced.

[0044] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
