[0001] The utility model belongs to the technical field of tires, and in particular relates to a tire pattern and a high-wear-resistant load-bearing tire. Background Art

[0002] For high-load vehicles, large-block tread blocks and grooves are generally used for layout and arrangement to ensure that the tread structure has sufficient deformation space and heat dissipation space to ensure its wear resistance during load-bearing driving. However, its guidance and handling will be relatively poor, especially in cornering and slippery road conditions. Due to the unreasonable distribution of the tread block structure and grooves, poor handling, poor braking performance and easy skidding may easily occur. Utility Model Content

[0003] Details of one or more embodiments of the present invention are set forth in the following drawings and description to make other features, objects, and advantages of the present application more readily apparent.

[0004] The utility model provides a tire pattern and a highly wear-resistant load-bearing tire, which divides the pattern blocks by staggered transverse steel sheets, and while ensuring the wear resistance, utilizes three longitudinal grooves of a fold line structure and two longitudinal steel sheets of a fold line structure to give the tire super strong guiding performance and anti-skid performance, which can break the water film and increase the tire's grip, thereby effectively ensuring the stability and safety of driving control.

[0005] The utility model discloses a tire pattern, comprising:

[0006] Tread;

[0007] Three longitudinal grooves, which are consistent in shape and size, and each of the longitudinal grooves is arranged in a continuous broken line structure along the movement direction of the tread;

[0009] A first transverse steel sheet is symmetrically arranged on both sides of each fold line of the first pattern block, and divides the first pattern block into first upper pattern blocks and first lower pattern blocks of different sizes and arranged alternately;

[0010] The second transverse steel sheet is symmetrically arranged on both sides of each fold line of the second pattern block, and divides the second pattern block into second upper pattern blocks and second lower pattern blocks of different sizes and arranged alternately;

[0011] The first lower tread block and the second upper tread block are equal in shape and size and are staggeredly arranged on both sides of the longitudinal steel sheet;

[0012] The first upper tread block and the second lower tread block are equal in shape and size and are staggeredly arranged on both sides of the longitudinal steel sheet.

[0013] In some embodiments, an upper opening area of ​​the longitudinal groove is larger than a bottom opening area of ​​the longitudinal groove.

[0014] In some embodiments, the angle of the fold line of the fold line structure at the bottom end of the longitudinal groove is not equal to the angle of the fold line of the fold line structure at the upper end of the longitudinal groove.

[0015] In some embodiments, an area of ​​the first upper tread block is greater than an area of ​​the first lower tread block; an area of ​​the second lower tread block is greater than an area of ​​the second upper tread block.

[0030] A tire pattern, comprising:

[0031] Tread;

[0032] Three longitudinal grooves 1, which are consistent in shape and size, and each longitudinal groove 1 is arranged in a continuous broken line structure along the movement direction of the tread;

[0033] A longitudinal steel sheet 2, which has the same shape as the longitudinal groove 1, has a fold line that is flush with the fold line of the longitudinal groove 1, is disposed between adjacent longitudinal grooves 1, and separates the tread between adjacent longitudinal grooves 1 into a first pattern block 3 and a second pattern block 4;

[0034] The first transverse steel sheet 5 is symmetrically arranged on both sides of each fold line of the first pattern block 3, and divides the first pattern block 3 into first upper pattern blocks 6 and first lower pattern blocks 7 of different sizes and arranged alternately;

[0035] The second transverse steel sheet 8 is symmetrically arranged on both sides of each fold line of the second pattern block 4, and divides the second pattern block 4 into second upper pattern blocks 9 and second lower pattern blocks 10 of different sizes and arranged alternately;

[0036] The first lower pattern block 7 and the second upper pattern block 9 are equal in shape and size and are staggeredly arranged on both sides of the longitudinal steel sheet 2;

[0037] The first upper pattern block 6 and the second lower pattern block 10 are equal in shape and size and are staggeredly arranged on both sides of the longitudinal steel sheet 2 .

[0038] Reference Figure 1 As shown, the tread is effectively divided under the action of the longitudinal groove 1 and the longitudinal steel sheet 2, that is, the deformation space of the tire pattern block can be effectively dissipated, and the same fold line structure setting can also ensure that the tire has a strong anti-skid ability. In addition, since the angles of each fold line are set equal, it also has good guidance. Further, the first transverse steel sheet 5 and the second transverse steel sheet 8 divide the first pattern block 3 and the second pattern block 4 into a plurality of V-shaped pattern blocks, and the adjacent pattern block structures are staggered in size. This bite-type staggered setting, when combined with the transverse steel sheet, can make the pattern block have good strength support to ensure the stability of the tire under stress and turning conditions.

[0039] In some embodiments, the upper opening area of ​​the longitudinal groove 1 is larger than the lower opening area of ​​the longitudinal groove 1. The angle of the fold line of the fold line structure at the lower end of the longitudinal groove 1 is not equal to the angle of the fold line of the fold line structure at the upper end of the longitudinal groove 1. The above arrangement can effectively reduce the cracks at the bottom of the tread groove and the phenomenon of stone clamping, avoid cutting by debris, and affect the service life of the tire.

[0040] In some embodiments, the area of ​​the first upper pattern block 6 is greater than the area of ​​the first lower pattern block 7 ; the area of ​​the second lower pattern block 10 is greater than the area of ​​the second upper pattern block 9 .

[0041] Furthermore, it also includes:

[0042] The V-shaped steel sheet 11 is disposed on the first upper tread block 6 and the second lower tread block 10, and its V-shaped opening direction faces the sidewall. The first upper tread block 6 and the second lower tread block 10 have relatively large areas, so the V-shaped steel sheet 11 is disposed on the first upper tread block 6 and the second lower tread block 10 to ensure the balance and stability of the force.

[0043] In some embodiments, the V-shaped steel sheet 11 on the first upper tread block 6 and the V-shaped steel sheet 11 on the second lower tread block 10 are symmetrically arranged on both sides of the longitudinal steel sheet 2. As shown in the figure, the V-shaped steel sheets 11 on the first upper tread block 6 and the second lower tread block 10 are arranged opposite to each other, and the opening directions of the two are relatively facing outward, that is, the same as the opening directions of the first upper tread block 6 and the second lower tread block 10.

[0044] In some embodiments, the angle of the fold line of the fold line structure of the longitudinal groove 1 is equal to the opening angle of the V-shaped steel sheet 11. The longitudinal groove 1 selects a suitable angle α, the angle α is 130°-145°, preferably 138°. The above setting can ensure that the tire will not generate excessive heat during long-distance driving on the highway, and can also provide grip under highway conditions.

[0045] In some embodiments, the area of ​​the tread on the outer side of the three longitudinal grooves 1 is 1.1-1.2 times the area of ​​the tread on the inner side of the three longitudinal grooves 1, thereby increasing the effective contact area of ​​the tire and improving the stability of the tire.

[0046] A highly wear-resistant load-bearing tire comprises: a tire pattern as described in any one of the above embodiments.
