Description

TECHNICAL FIELD

[0002] With the rapid development of the automobile industry, consumers' requirements for vehicle performance are increasing, and the performance of tires, as the only part in contact with the ground, is crucial to the power and handling of sports cars. The traditional tire often cannot meet the needs of the vehicle for grip and traction, handling and stability, drainage capacity and rolling resistance, and response speed when driving at high speed and intense handling. Therefore, it is inevitable to develop ultra-high performance tires to adapt to the upgrading of automobile performance.

[0003] At the same time, with the gradual enhancement of environmental awareness, the global attention to environmental protection continues to rise, and the rolling resistance of tires is closely related to vehicle fuel consumption. Reducing tire rolling resistance can effectively reduce fuel consumption and carbon dioxide emissions of cars, which prompts tire manufacturers to develop green and environmentally friendly tires, use new materials and design, and reduce rolling resistance to the greatest extent without sacrificing performance, achieve energy saving and emission reduction, and meet the requirements of sustainable development.

[0004] However, the reduction of tire rolling resistance and the improvement of other performance are accompanied by the design of tire pattern structure and the tread polishing process after the design of tire pattern structure.

[0054] As shown in FIG. 1, the tire is provided with a central block 1, and a plurality of "E-shaped" crown blocks 2 are arranged in a ring shape on both sides of the central block 1. Figure 8 As shown, the block wall edge of the crown block 2 is designed in a large-angle multi-dimensional manner, a longitudinal small groove 4 is formed in the crown block 2, the groove opening is arranged opposite to the central block 1, and the front longitudinal groove 6 is in communication with the central block 1 and the crown block 2, thereby improving the water drainage.

[0055] As shown in FIG. 1, the tire is provided with a central block 1, and a plurality of "E-shaped" crown blocks 2 are arranged in a ring shape on both sides of the central block 1. Figure 8 As shown, a fine sipe 7 is further arranged on the crown block 2 and penetrates through the longitudinal small groove 4, the fine sipe 7 divides the crown block 2 into four small blocks, which can optimize the water film penetration capacity, reduce the water accumulation under a single block, and shorten the wet braking distance.

[0056] As shown in FIG. 1, the tire is provided with a central block 1, and a plurality of "E-shaped" crown blocks 2 are arranged in a ring shape on both sides of the central block 1.

[0057] As shown in FIG. 1, the tire is provided with a central block 1, and a plurality of "E-shaped" crown blocks 2 are arranged in a ring shape on both sides of the central block 1. Figure 8 As shown, the rear longitudinal groove 9, the front longitudinal groove 6, the transverse groove 10, and the shoulder transverse groove 5 are matched with each other, and the longitudinal groove and the transverse groove are designed in a mutual communication manner, which can effectively ensure that the tire can rapidly drain water when entering the water accumulation road surface, and ensure the grip and traction of the tire on the wet road surface.

[0058] As shown in FIG. 1, the tire is provided with a central block 1, and a plurality of "E-shaped" crown blocks 2 are arranged in a ring shape on both sides of the central block 1. Figure 8 As shown, the shoulder transverse groove 5 is designed in an open type, which improves the water drainage performance, braking performance, and handling performance, and the shoulder block 3 is designed in a large-pitch combination, which can effectively improve the overall rigidity of the shoulder block 3, ensure the accuracy during turning, and the fine sipe 11 arranged on the block can effectively "cut" the noise interval on the tire surface when the tire is running at a high speed, reduce the spread of noise, and improve the comfort of driving and riding.

[0059] As shown in FIG. 1, the tire is provided with a central block 1, and a plurality of "E-shaped" crown blocks 2 are arranged in a ring shape on both sides of the central block 1. Figure 8As shown, the "SPORT-X" artistic font 12 is designed on the central block 1 of the tire, which is circumferentially spaced eight equal parts, and the font is designed in an embedded manner, which not only implies the type of the pattern, but also increases the overall aesthetics of the tire.

[0060] As shown in the drawings, Figure 9 The first and second regions of the pattern are mirror images and are staggered left and right, with a staggered distance of 30.1mm, which can effectively optimize the overall performance of the tire, significantly enhance the performance of the tire in complex driving environments and road conditions, and also have a sense of sports and fashion, thereby improving the overall visual effect of the vehicle.

[0061] As shown in the drawings, Figure 9 The pattern includes three different sizes of pitches, namely a first pitch L1, a second pitch L2 and a third pitch L3, and the pitch ratio is L1<L2<L3, the pitch ratio is L1:L2:L3=1.0:(1.10~1.15):(1.20~1.25), and the pitch ratio is an irrational number ratio.

[0062] From the perspective of finite element analysis, when the pitch width is an irrational number ratio, it is beneficial to reduce the probability of resonance, thereby reducing tire noise. The first pitch L1, the second pitch L2 and the third pitch L3 are arranged along the tire circumference, and the pitch arrangement size is staggered, which further reduces the resonance ratio and improves the overall handling and comfort of the tire.

[0065] The design of the best "arch bridge type" pattern groove, "S" shape pattern groove and "E block type" pattern block, arrow-shaped pattern block, knife-sharp pattern block and strip-shaped pattern block greatly improves the tire's passing rate on dry flat, wet, gravel, muddy, mountainous winding, rocky slope, drainage, mud and sand, and other functions, improves the stability and rapid turning performance, and gives the tire super strong grip and wear resistance.

[0066] And for this development of ultra high performance sports green tire formula: with brake safety, good elasticity, small rolling resistance, low fuel consumption, low heat, wear resistance, puncture resistance, carrying capacity, ride comfort and other advantages, compared with traditional tires, highlights the environmental protection, energy saving, new technology, new materials and other advantages.
