Description

Technical Field

[0001] The utility model belongs to the technical field of tire treads, and particularly relates to a tire tread and an all-terrain tire. Background Art

[0002] In recent years, there has been a trend of "boxy cars" in the domestic automobile market. Major automobile manufacturers have successively launched off-road vehicles, including hardcore off-road vehicles and mild off-road vehicles, etc. Most of the driving conditions are mainly paved roads in the city, and a small number of them will go to non-paved roads such as muddy and sandy roads with more complex road conditions to play off-road; because of the addition of square-shaped styling elements in appearance, we collectively call this type of car a "boxy car". With the emergence of this type of car, all-terrain off-road tires have also emerged following this trend, and the market sales show an increasing trend.

[0003] For traditional off-road tires, their groove tread blocks are relatively large and the off-road ability is strong, but the disadvantages are also obvious, that is, the noise and comfort performance are relatively poor; for ordinary SUV tires, they do not pay attention to off-road performance in product design. Both the tread blocks and the grooves focus on road performance, so they cannot meet the demands of the driver and passengers for occasional off-road driving. Summary of the Utility Model

[0040] A tire tread pattern is provided with a plurality of middle tread pattern groups distributed along the tire movement direction and side tread pattern groups located on both sides thereof; further comprising:

[0041] A middle third transverse groove 5, which is in a three-fold section structure and is arranged between adjacent middle tread pattern groups;

[0042] A side longitudinal groove 2, which is arranged between the middle tread pattern group and the side tread pattern group, and both ends thereof are respectively connected to the corresponding middle third transverse groove 5, and the upper and lower adjacent side longitudinal grooves 2 as a whole are in a three-fold section structure;

[0043] A pair of middle longitudinal grooves 1, which longitudinally penetrate and are symmetrically arranged about the center on both sides of the middle tread pattern group, and each middle longitudinal groove 1 is in a three-fold section structure;

[0044] A middle transverse groove, which transversely penetrates the middle tread pattern group; the middle transverse groove includes a middle first transverse groove 3 located between a pair of middle longitudinal grooves 1 and middle second transverse grooves 4 located on both sides thereof and symmetrically arranged about the center; both the middle first transverse groove 3 and the middle second transverse grooves 4 are in a three-fold section structure and are in an overall continuous structure.

[0045] Wherein, Figure 1As shown, the three-fold structure of the middle third transverse groove 5 is formed by connecting two L-shaped structures. The folding points of the L-shaped structures are located on the middle first tread block 9 and the middle second tread block 10. Through the above settings, the first "Z" - shaped structure is formed; the side longitudinal groove 2 is in the shape of the second "Z" - shaped structure, and its middle section is collinear with the middle third transverse groove 5 as a whole; the middle longitudinal groove 1 is in the shape of the third "Z" - shaped structure; the middle first transverse groove 3 and the middle second transverse groove 4 are in the shape of the fourth "Z" - shaped structure and the fifth "Z" - shaped structure, and the middle first transverse groove 3 and the middle second transverse groove 4 form an "S" - shaped structure as a whole. Through the above five "Z" - shaped structures, the middle tread group is separated, so as to form the middle first tread block 9 and the middle second tread block 10 located at the upper and lower positions in the middle, the middle third tread block 11 and the middle fourth tread block 12 located at the upper and lower positions on the left, and the middle fifth tread block 13 and the middle sixth tread block 14 located at the upper and lower positions on the right; the middle first tread block 9 and the middle second tread block 10, the middle fourth tread block 12 and the middle fifth tread block 13, and the middle third tread block and the middle sixth tread block 14 are respectively centrosymmetrically arranged; the tread blocks in the middle tread group are separated by different "Z" - shaped structures to form an interlocking structure. During the tire's force - bearing process, they can provide support for each other to improve its overall rigidity. And the "Z" - shaped structures at different angles also provide the tire's friction performance in different directions. Furthermore, the inter - connected structure design ensures its sufficient drainage and sand - discharging capabilities to ensure its certain off - road performance.

[0046] The shapes and sizes of the middle first tread block, the middle fourth tread block, and the middle third tread block are all inconsistent, which also avoids the noise superposition after the tread blocks hit the ground, thereby improving its sound - proof effect and giving better comfort to the driver and passengers on the paved road surface.

[0047] In some embodiments, it further includes:

[0048] The side second transverse groove 7 is located between adjacent side tread groups and is in a coherent structure with the middle third transverse groove 5 as a whole;

[0049] The side first transverse groove 6 traverses the side tread group horizontally and is in a coherent structure with the middle transverse groove as a whole.

[0050] The transverse groove design of the coherent structure can effectively drain the sediment-laden water as much as possible, improving the off-road performance of the tire. However, it may also lead to an increase in noise. Therefore, further detailed treatments are carried out on the first side transverse groove 6 and the second side transverse groove 7 respectively to reduce the generation of noise in the shoulder part of the tire. By providing a first side transverse narrow groove and a first side transverse wide groove that are connected and communicated in the first side transverse groove 6; the first side transverse narrow groove is connected and communicated with the side longitudinal groove 2, and its width is smaller than that of the first side transverse wide groove, so as to block and reduce the transmission of noise at the first side transverse groove 6. By providing a side transverse groove block 8 to block and reduce the transmission of noise at the second side transverse groove 7. Specifically, the side transverse groove block 8 is arranged in the second side transverse groove 7 and is located at a position connected and communicated with the middle third transverse groove 5. The height of the side transverse groove block 8 is 1 / 2 of the groove depth of the second side transverse groove 7; and a groove is provided on the upper end surface of the side transverse groove block. The depth of the groove is 1 / 4 of the groove depth of the second side transverse groove 7. The semi-closed structure design not only plays a role in blocking and reducing the transmission of noise, but also ensures normal drainage.

[0051] At the same time, the side pattern group forms a first side pattern block 15 and a second side pattern block 16 with different axial widths and circumferential widths through the separation of the first side transverse groove, the second side transverse groove and the side longitudinal groove. By controlling the width of the pattern block, the noise can be effectively controlled within a certain acceptable range, and the handling performance of the tire can also be ensured; the grounding areas of the two pattern blocks are different, generating different frequencies of excitation for the impact on the road surface, which can further reduce the noise.

[0052] In traditional off-road tires, the steel sheet structure is usually not provided mainly to ensure their off-road performance. In this application, in order to better adapt to paved roads, corresponding steel sheets are provided on each pattern block structure to adjust the rigidity strength of each pattern block, thereby improving the comfort and handling performance of the driver and passengers on paved roads.

[0053] In some embodiments, it further includes:

[0054] The first side steel sheet and the second side steel sheet are both arranged in a three-fold segment structure and semi-penetrate the first side pattern block 15 and the second side pattern block 16, and their inner ends are connected and communicated with the side longitudinal groove 2;

[0055] The opening directions of the folded segments of the first side steel sheet and the second side steel sheet are inconsistent. Among them, the first side steel sheet and the second side steel sheet form a sixth "Z" - shaped structure and a seventh "Z" - shaped structure.

[0056] The middle first steel sheet 17 is arranged in a V - shaped structure and penetrates through the middle first pattern block 9 and the middle second pattern block 10;

[0057] A pair of second middle steel sheets 18 are disposed semi-penetrating through the first middle tread block 9 and the second middle tread block 10, and are located on both sides of the first middle steel sheet 17;

[0058] The third middle steel sheet 19 is disposed penetrating through the fourth middle tread block 12 and the fifth middle tread block 13 in a V-shaped structure;

[0059] The fourth middle steel sheet 20 is disposed semi-penetrating through the fourth middle tread block 12 and the fifth middle tread block 13, and is located on both sides of the third middle steel sheet 19;

[0060] The fifth middle steel sheet 21 is disposed penetrating through the third middle tread block 11 and the sixth middle tread block 14 in a V-shaped structure;

[0061] The sixth middle steel sheet 22 is disposed semi-penetrating through the third middle tread block 11 and the sixth middle tread block 14, and is located on both sides of the fifth middle steel sheet 21.

[0062] The V-shaped opening directions of the first middle steel sheet 17, the third middle steel sheet 19, and the fifth middle steel sheet 21 are inconsistent.

[0063] In summary, due to the mutually occlusive structural design of the tread blocks in the middle tread group, their support is relatively strong. Therefore, by combining the penetrating steel sheets and the semi-penetrating steel sheets, the overall strength of the tread blocks can be adjusted. At the same time, the setting of the steel sheets is also more conducive to breaking the water film and improving the braking performance of the tire.

[0064] The tread blocks of the side tread group are separated by the first side transverse groove 6 with a varying width and the second side transverse groove 7 provided with side transverse groove stoppers 8, and are combined with the first side steel sheet and the second side steel sheet, thereby improving the grip ability while ensuring the shoulder controllability, and also strengthening the tear resistance of the tread blocks and extending the service life of the tire.
