DETAILED DESCRIPTION
[0024] The utility model will be further described in combination with the drawings and specific embodiments, but the protection scope of the utility model is not limited to this.
[0025] For example, Figure 1As shown, a tire tread block 301 is composed of a heptagon ABCDEFG, which includes a rectangle DEFG, a parallelogram ACDG on one side of the rectangle DEFG, and an obtuse triangle ABC on the other side of the parallelogram ACDG. Roller ridges 5 are provided on the surface of the rectangle DEFG. The tire tread block 301 increases the contact area between the tire and the ground, improving not only grip but also driving performance. The roller ridges create additional drainage channels when the tire contacts the ground and break the continuity of the tire surface, thereby reducing the overall noise level.
[0026] In this design, the length EF of rectangle DEFG is 30 mm, or 32 mm, or any length between 30 and 32 mm; the width DE is 6 mm, or 7 mm, or any value between 6 and 7 mm; the base AC of parallelogram ACDG is 30 mm, or 32 mm, or any value between 30 and 32 mm; the height OD is 16 mm, or 17 mm, or any value between 16 and 17 mm; and the base AC of obtuse triangle ABC is 30 mm, or 32 mm, or any value between 30 and 32 mm; the height BP is 3 mm, or 4 mm, or any value between 3 and 4 mm.
[0027] The thickness of the tread pattern block 301 is 20 mm, which can be 22 mm, or any value between 20 and 22 mm.
[0028] like Figure 2 As shown, a tire shoulder tread pattern 101 is composed of a pentagon KLMNR, which includes a rectangle KLMR and an obtuse triangle MNR. The length ML of the rectangle KLMR is 38 mm, or 40 mm, or any length between 38 and 40 mm, and the width DE is 30 mm, or 32 mm, or any value between 30 and 32 mm. The base MR of the obtuse triangle MNR is 38 mm, or 40 mm, or any length between 38 and 40 mm, and the height NQ is 1 mm, or 5 mm, or any value between 1 and 5 mm.
[0029] See Figure 3 The present invention provides a schematic diagram of the structure of a tire tread pattern composed of the above-mentioned pattern blocks.
[0030] A kind of crown pattern ring, including two single crown pattern rings, wherein the first single crown pattern ring 3 is spaced apart by the crown pattern block 301 with rolling thread and the crown pattern block 301 without rolling thread, and the crown pattern block 301 adopts equal pitch design, and the pitch number is 52;As shown in Figure 4 、 5 The above-mentioned spacing is the groove 6 formed by 2D steel sheet between the crown pattern block 301 with rolling thread and the crown pattern block 301 without rolling thread, and the groove width W1 of the groove 6 is 0.5 mm, which can also be 1.2 mm, and can also be any value between 0.5-1.2 mm, and the groove depth L1 is 11 mm, which can also be 13 mm, and can also be any value between 11-13 mm.
[0031] The second single crown pattern ring 4 is arranged in central symmetry with the first single crown pattern ring 3, and the groove 2 is arranged between the first single crown pattern ring 3 and the second single crown pattern ring 4;The groove arranged by the first single crown pattern ring 3 and the groove arranged by the second single crown pattern ring 4 are arranged in staggered manner;The crown pattern ring is arranged with groove at specific position, and the pattern blocks at different positions take turns to bear main pressure due to the adjustment of the groove, so as to avoid the rapid wear of local pattern blocks due to excessive stress;At the same time, the setting of the groove provides an effective channel for heat dissipation, and improves the heat dissipation performance of the tire;In addition, the staggered arrangement of the groove 6 ensures the overall stability of the tire grip, so that the stress of each part of the tire is more uniform during driving, effectively prolonging the overall service life of the tire.
[0032] A kind of crown pattern, including two crown pattern rings, which are arranged in central symmetry, and the groove 2 is arranged between the two crown pattern rings;The central symmetric design of the two crown pattern rings makes the stress of each part of the tire more uniform during driving, and provides more stable longitudinal grip;At the same time, the setting of the groove avoids the tire skidding phenomenon caused by local water accumulation.
[0033] A kind of tread pattern, including crown pattern and shoulder pattern, the shoulder pattern 1 is in whole week integrated structure, and the inside is protruding continuous obtuse angle triangle MNR, which corresponds to the obtuse angle triangle ABC in the first single crown pattern ring 3, i.e. the obtuse angle triangle MNR in each shoulder pattern section 101 is in close parallel relationship with the obtuse angle triangle ABC in the first single crown pattern ring 3 about tire transverse direction, and the size of the obtuse angle triangle MNR is close to that of the obtuse angle triangle ABC;As shown in Figure 4As shown, the continuous obtuse triangle MNR on the inner side of the tire shoulder tread is the same as the obtuse triangle AB'C formed between the sides of the tread blocks. That is, the obtuse triangle AB'C is formed by the intersection of the extension lines of the BC line of the un-rolled tread block and the AB line of the tread block in groove 6. The vertex B' is the intersection point of the extension lines of the BC line of the un-rolled tread block and the AB line of the tread block in groove 6. A tread groove 2 is set between the tire shoulder tread and the first single tread ring 3. The design of the tire shoulder tread with a whole-circle structure can enhance the strength and stability of the tire shoulder and reduce deformation. The design of the obtuse triangle may increase the contact area and improve grip, thereby extending the tire's service life.
[0034] The shoulder tread pattern consists of shoulder tread segments with equal pitches, including a section of obtuse-angled triangle MNR, with a total pitch of 52. The equal pitch design makes the tire roll more evenly and the force on each part more balanced, further improving the tire's durability.
[0035] In this embodiment of the invention, the saturation of the tread pattern is 78%, which can improve the product mileage to a certain extent.
[0036] like Figure 3 , Figure 6 As shown, the tread groove 2 adopts an alternating design of zigzag and straight lines. The width W2 of the zigzag tread groove 2 is 16 mm, or it can be 17 mm, or any value between 16 and 17 mm. The depth L2 of the zigzag tread groove is 20 mm, or it can be 22 mm, or any value between 20 and 22 mm. The width W3 of the straight tread groove 2 is 2 mm, or it can be 3 mm, or any value between 2 and 3 mm. The depth L3 of the straight tread groove is 16 mm, or it can be 17 mm, or any value between 16 and 17 mm. The alternating design of zigzag and straight lines of the tread grooves increases the heat dissipation capacity of the tire and effectively reduces rolling resistance, thereby achieving fuel saving.
[0037] In summary, the tire shoulder pattern and the tread pattern formed by this utility model, through optimized tire shoulder pattern design, may enhance the strength and stability of the tire shoulder and reduce deformation through an integral structure; the obtuse-angled triangle design may increase the contact area and improve grip, thereby extending the tire's service life and providing customers with a more economical and reliable tire solution.
