[0040] The technical features of the present invention are further described below in conjunction with the accompanying drawings and specific embodiments.

[0041] like Figure 1 As shown, the present application is a reinforced, highly stable and highly maneuverable tire tread structure, the structure of which includes a tread 1, wherein an annular longitudinal main pattern block 2 is provided at the center of the tread 1; the longitudinal main pattern block 2 is used as a reference, the right side is the outer side 3 of the tread, and the left side is the inner side 4 of the tread; the outer side 3 of the tread includes a longitudinal groove three 5 and a longitudinal narrow groove four 6, and a 1 / 4 pattern block two 7 is combined with an outer shoulder pattern block 8; the inner side 4 of the tread includes a longitudinal groove two 9 and a longitudinal groove one 10, and a 1 / 4 pattern block one 11 and an inner shoulder pattern block 12. It can be seen from the above and the accompanying drawings that the pattern block structure on the tread 1 is an asymmetric pattern form.

[0042] The longitudinal main pattern block 2 is provided with a gradual angle cut 13 with a gradual angle cut design, and a gradual angle cut steel sheet 1 matched with the gradual angle cut 13 is provided in the longitudinal main pattern block 2, and the gradual angle cut steel sheet 1 is located at the inner side, with the center line as the reference;

[0043] At the 1 / 4 position of the outer side of the tread 3, there is a gradually changing chamfer design of the gradually changing chamfer two 14 on one side of the tread block two 7. Inside the 1 / 4 tread block two 7, there is a gradually changing chamfer steel sheet two arranged in cooperation with the gradually changing chamfer two 14. On the 1 / 4 tread block two 7, there is also a transverse groove three 15. As shown in Figure 2, the transverse groove three 15 is a combination of a groove and a steel sheet five 27. Such a setting can ensure the function of the groove and also ensure the rigidity of the 1 / 4 tread block two 7.

[0044] On the outer shoulder tread block 8, there are an outer transverse groove one 16 and an outer transverse groove two 17, which form an "integrated" design with the 1 / 4 tread block two 7, increasing the rigidity of the tread blocks on the entire outer side of the tread, and being beneficial to improving stability and handling performance. And the 1 / 4 tread block two 7 and the outer shoulder tread block 8 adopt a "two-in-one" form of expression. The outer transverse groove one 16 and the outer transverse groove two 17 adopt the design language of an asymmetric "diamond" chamfer. Its specific form is shown in Figure 3.

[0045] The 1 / 4 tread block one 11 includes an L-shaped groove one 18 and an L-shaped groove two 19 with a vertical "L"-shaped groove design. The L-shaped groove one 18 and the L-shaped groove two 19 are shown in Figure 4.

[0046] As Figure 5 shown, the vertical L-shaped groove one 18 corresponds to the gradually changing chamfer one 13, forming a horizontal "L" shape; the vertical L-shaped groove two 19 corresponds to the inner steel sheet two 20, forming a whole, and the inner steel sheet two 20 adopts an "inverted hook type" design. For the specific design, see Figure 6 shown. The position adopts an "off-center" form, improving the flexibility of the tire design.

[0047] The inner transverse groove 21, the reverse chamfer one 22, and the reverse chamfer two 23 form the shape of the Chinese character "ding", and one side of the inner transverse groove 21 adopts a gradually changing chamfer form, increasing the grounding area of the tire.

[0048] The gradually changing chamfer one 13 and the gradually changing chamfer steel sheet one adopt the design language of a "folded type". For the specific design, see Figure 7 shown. Two different angles are combined, the chamfer depth is 2 mm, the depth of the gradually changing chamfer steel sheet one is a gradually changing structure, the deepest position is 3.5 mm, and the shallowest position is 1 mm.

[0049] Similarly, the gradually changing chamfer two 14 and the gradually changing chamfer steel sheet two also adopt the design language of a "folded type". For the specific design, see Figure 7As shown, it corresponds to the gradient cut angle 13 and the gradient cut angle steel sheet 1 to form an overall effect; the gradient cut angle steel sheet 2 is also combined with two different angles, and the lower end point of the gradient cut angle steel sheet 2 is not on the same horizontal line as the lower end point of the gradient cut angle 2 14; and combined with the inner wall of the longitudinal narrow groove four 6, a "zigzag" longitudinal narrow groove four 6 is formed.

[0050] like Figure 8 As shown, the 1 / 4 pattern block 2 7 is close to the side of the longitudinal main pattern block 2, and the pattern block is expressed by the design language of "reverse" cutting angle. The reverse cutting angle 3 26 is offset 1° above and below the horizontal line. The gradual cutting angle 3 24 is first offset 1° inward from the horizontal, and then offset 2°, and the depth is 2.0mm-2.5mm.

[0051] like Fig. 9 As shown, the side of the 1 / 4 pattern block 2 7 near the outer shoulder pattern block 8 is divided into two sections, which are connected by a gradual cut angle 2 14 and offset by 2 degrees, thereby forming a "zigzag" longitudinal narrow groove 4 6. And the bottom of the longitudinal groove on this side is raised 1mm to form a raised ring, which enhances the high rigidity and stability of the entire pattern block.

[0052] The transverse groove of the tread block 27 at 1 / 4 adopts the design language of "groove + steel sheet". The depth of the transverse groove is 2.5mm-3.0mm. The depth of the steel sheet is below the transverse groove, reaching the bottom of the groove. This design can ensure the smooth discharge of water flow on the one hand, and on the other hand, compared with the traditional transverse groove, it can reduce noise and greatly enhance the rigidity and strength of the tread block, providing control stability.

[0053] The outer shoulder pattern block 8 includes an outer transverse groove 1 16 and an outer transverse groove 2 17, which are "integrated" with the 1 / 4 pattern block 2 77, and the 1 / 4 pattern block 2 7 and the outer shoulder pattern block 8 are designed in a "two-in-one" form, connected by a longitudinal narrow groove 4 6 to form a wide overall pattern block. For detailed structure, see Fig.10 This setting not only increases the contact area of ​​the entire tread block, but also enhances the overall driving controllability and cornering stability, thus enhancing the overall performance of the tire.

[0054] The side of the outer shoulder pattern block 8 close to the longitudinal narrow groove 46 adopts a design form of a gradual chamfer 425 with an offset of 2° and a chamfer depth of 1.5mm-1.8mm, which increases the excellent response of the tire during braking, braking and turning, and improves the safety performance.

[0055] like Fig.11As shown, the outer lateral groove 1 16 and the outer lateral groove 2 17 adopt an asymmetric "diamond" cut angle design, the purpose of which is to cope with the changes in different road surfaces, including dry land and wet land; the outer lateral groove 1 16 and the outer lateral groove 2 adopt a structure combining arc lines and straight lines, breaking the previous design form of simple arc lines and straight lines, and the two sides of the groove adopt an asymmetric "diamond" cut angle structure, such as Fig.10 As shown, the cut angles on both sides of the outer transverse groove 16 are composed of a straight cut angle 161 and an arc cut angle 162. The straight cut angle 161 is arranged in cooperation with the straight line segment of the outer transverse groove 16, and the arc cut angle 162 is arranged in cooperation with the arc segment of the outer transverse groove 16. One side of the outer transverse groove 16 is a gradual cut angle, the lower edge of the cut angle does not reach the lower end of the groove, the deepest position is 1mm-1.2mm, and the widest position is 0.8mm-1mm; the cut angle on the other side of the outer transverse groove 16 is cut from the upper end of the groove to the lower end of the groove, the deepest position is 1mm-1.2mm, and the widest position is 0.8mm-1mm.

[0056] The shape of the outer transverse groove 2 17 is the existing traditional groove style. The front end of the outer transverse groove 2 17 has a reinforcing rib with a depth of 2mm-2.5mm. The cutting angle of the outer transverse groove 2 17 also adopts an asymmetric "diamond" cutting structure. The gradient cutting angle depth on one side of the outer transverse groove 2 17 is 0-1.5mm, and the widest width of the cutting angle on this side of the outer transverse groove 2 17 is 1.2mm, which corresponds to the gradient cutting angle 4 25; the cutting angle depth on the other side of the outer transverse groove 2 17 is 0-1.0mm, and the widest width of the cutting angle on this side is 1.2mm. The cutting angles on both sides of the outer transverse groove 2 17 are not cut to the bottom of the groove. The design language reference of "=" formed by two longitudinal small grooves 28 at the bottom of the shoulder pattern Fig.12 Each shoulder pattern block is designed with two longitudinal small grooves 28, which can not only increase the aesthetics of the design, but also improve the heat dissipation performance of the tire and ensure the durability of the tire.

[0057] like Figure 1 As shown, the 1 / 4 pattern block 11 includes an L-shaped groove 18 and an L-shaped groove 2 19, and the transverse steel sheet parts of the L-shaped groove 18 and the L-shaped groove 2 19 are both offset 4° upward from the horizontal line.

[0058] In the radial direction of the tire, a section from the groove transverse steel sheet 1 to the opening of the L-shaped groove 18 is the upper section of the L-shaped groove 18, and a section from the groove transverse steel sheet 1 to the inner bottom end of the L-shaped groove 18 is the lower section of the L-shaped groove 18. The upper section of the L-shaped groove 18 is an arc-shaped cut-angle groove, and the lower section of the L-shaped groove 18 is a gradient cut-angle groove. In the radial direction of the tire, the distance from the groove transverse steel sheet 1 to the surface of the tread 1 is gradually set from 4.5MM to 5.7MM.

[0059] The groove transverse steel sheet 2 is buried in the middle section of the L-shaped groove 19 in the depth direction; in the radial direction of the tire, a section from the groove transverse steel sheet 2 to the opening of the L-shaped groove 19 is the upper section of the L-shaped groove 19, and a section from the groove transverse steel sheet 2 to the inner bottom end of the L-shaped groove 19 is the lower section of the L-shaped groove 19. The upper section of the L-shaped groove 19 is an arc-shaped cut-angle groove, and the lower section of the L-shaped groove 19 is a gradient cut-angle groove; in the radial direction of the tire, the distance from the groove transverse steel sheet 2 to the surface of the tread 1 is gradually set from 4.5MM to 5.7MM.

[0060] like Fig.13 As shown, the tire pattern is divided into five pitches, namely pitch PA, pitch PB, pitch PC, pitch PD, and pitch PE.

[0061] The upper section of the L-shaped groove 18 and the upper section of the L-shaped groove 2 19 adopt an "arc-shaped" cutting form. When the pitch is PA, PB, and PC, the cutting width of the L-shaped groove 18 and the L-shaped groove 2 19 is 0.5mm. When the pitch is PD and PE, the cutting width of the L-shaped groove 18 and the L-shaped groove 2 19 is 0.8mm. The cutting depth of the L-shaped groove 18 and the L-shaped groove 2 19 is uniformly 0.8mm.

[0062] The lower section of L-shaped groove 18 and the lower section of L-shaped groove 2 19 respectively adopt a gradual chamfering structure, the chamfering depth is 0-3mm, and the deepest position is consistent with the chamfering depth of the steel sheet. The above design ensures the function of draining water and cutting the water film on the inside, and also ensures that the overall rigidity of the pattern will not be reduced.

[0063] The inner steel sheet 20 in the inner shoulder pattern block 12 adopts a "hook-shaped" design language, and is positioned in a "non-center" form, occupying 3 / 7 of the entire pattern block, and the buried depth of the inner steel sheet 20 is 1 mm. The purpose is to play a role in cutting the water film in the early stage of the tire. After the steel sheet is worn out in the later stage, the rigidity of the pattern block becomes larger as a whole, and the stability is stronger.
