Description

Technical Field

[0001] The present invention relates to the technical field of automobile tires, and in particular to a coupled bionic tire pattern structure. Background Art

[0002] As the sole contact component between a vehicle and the road, tires fulfill multiple functions, including supporting the vehicle body, buffering external forces, and transmitting traction and braking force. Their structural design directly impacts vehicle performance indicators such as driving safety, handling stability, fuel economy, and ride comfort. The tread pattern, the key point of contact between the tire and the road, has a geometrical characteristic that significantly influences the tire's wear resistance and ground contact pressure distribution. Tires are in constant contact with various complex road surfaces during driving, frequently subject to friction and impact loads. Therefore, their wear resistance is crucial for extending tire life and ensuring driving safety. Deteriorating tire wear resistance not only leads to premature tread wear and reduced driving stability, but also requires frequent tire replacement, resulting in wasted rubber resources and increased operating costs. Furthermore, uneven tread ground contact pressure distribution is a significant factor contributing to abnormal wear, further exacerbating the trend of tire performance degradation. Therefore, developing a tire pattern structure with excellent wear resistance and balanced distribution of tread ground pressure will not only help reduce material loss and extend the service life, but also improve the reliability of tires under various working conditions, helping vehicles develop in the direction of energy conservation and environmental protection, and complying with the strategic requirements of green manufacturing and low-carbon economy.

[0003] Bionic design, as one of the key means of improving the performance of engineering structures, has been widely applied in recent years in fields such as machinery, materials, and transportation. Throughout evolution, the surface structures of many organisms have developed superior functional forms through long-term adaptation to environmental changes. The desert black-tailed scorpion, a typical organism living in arid and variable terrain, exhibits remarkable adaptability in terms of support, anti-slip properties, and wear control through its dorsal structure. Research has found that the dorsal surface of the black-tailed scorpion exhibits a remarkably regular pattern of V-shaped grooves, arc-shaped protrusions, and dimples. These structures help disperse pressure and maintain stable ground contact during movement, thereby enhancing its adaptability to complex terrain. Applying these backplate structural features to tire tread design, by constructing a coupled V-shaped groove, arc-shaped pattern, and dimple arrangement, can significantly improve the tire's contact patch and pressure distribution uniformity, effectively enhancing its wear resistance. This provides a reliable theoretical basis and design path for the biomimetic optimization of high-performance tires. Summary of the Invention

[0004] The purpose of the present invention is to provide a coupled bionic wear-resistant tire pattern structure to improve the wear resistance of the tire when the vehicle is driving, improve the uniformity of ground pressure distribution, and reduce tire wear.

[0005] The present invention achieves the above technical objectives through the following technical means.

[0006] A coupled bionic wear-resistant tire pattern structure includes shoulder pattern transverse grooves, transition area transverse grooves, longitudinal grooves, a pit structure and a central rib; the pattern block unit is designed based on the black thick tail scorpion back plate structure; the shoulder transverse pattern grooves include shoulder-arc pattern grooves and shoulder-V-shaped pattern grooves; the transition area transverse pattern grooves include transition-arc pattern grooves and transition-V-shaped pattern grooves; the shoulder pattern transverse grooves and the transition area transverse grooves are equidistantly arranged in the circumferential direction; the pit structure is equidistantly arranged in the axial direction between every two adjacent shoulder pattern transverse grooves.

[0007] Furthermore, the transverse grooves of the shoulder pattern, the transverse grooves of the transition area, and the pit structure are units that imitate the geometric structure of the black-tailed thick scorpion's back plate.

[0008] Furthermore, the shoulder transverse pattern grooves are arranged in a circular array with the tire axis as the center.

[0009] Furthermore, the shoulder-arc groove has an arc curvature radius of W 1 is 33-56mm, width is 4-5mm, and depth is 4.8-5.6mm.

[0010] Furthermore, the dimple structure has a diameter of 4mm and a depth of 1mm. The dimple structure is symmetrically arranged and evenly spaced about the central rib. The distance between each pair of adjacent shoulder pattern transverse grooves is 6mm, and the dimples are evenly spaced in the shoulder area. Eight dimples form a group between two V-shaped grooves, forming a circular array of 52 groups centered on the tire axis.

[0011] Furthermore, the transition area transverse pattern grooves are arranged in a circular array of 56 grooves with the tire axis as the center.

[0012] Furthermore, the transition-arc groove has an arc curvature radius of W 2 is 21-22mm, width is 4-5mm, and depth is 4.8-5.6mm.

[0013] Furthermore, the shoulder transverse grooves and the transition region transverse grooves are axially symmetrically arranged and equidistantly distributed about the central rib 4, and the distance between adjacent transverse grooves in the circumferential direction is 4 to 5 mm.

[0014] Furthermore, the central rib has a width of 23 mm and a depth of 7 mm.

[0015] Furthermore, the longitudinal groove has a depth of 8 mm and a depth of 7 mm.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) The present invention couples the tire pattern with bionic design, and the tread pattern geometry is similar to that of the black thick-tailed scorpion back plate. Compared with ordinary tires, under standard load and standard air pressure, the ground contact pressure value at the tire shoulder is reduced. With the increase of load, the ground contact area is increased relative to ordinary tires. Under braking, driving, side deviation and roll conditions, the ground contact area is also increased, the ground contact pressure distribution uniformity is improved, and the tire wear resistance is improved.

[0018] (2) The tread pattern is designed with grooves of various angles and depths, which can improve the drainage performance when driving on wet roads while ensuring the effective contact area of the tire; the transverse grooves on the shoulder and the transverse grooves in the transition area are arranged symmetrically and equidistantly, which can ensure good wear resistance of the vehicle under forward conditions.
