Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a high-performance all-terrain off-road tire. Background Technology

[0002] In recent years, with economic development, the global all-terrain vehicle tire market has grown rapidly. Demand for all-terrain tires is increasing not only in developed countries but also in emerging countries and regions such as the Asia-Pacific and Africa. Infrastructure development, agricultural growth, and the rise of outdoor recreational activities in these regions have provided a broad market prospect for all-terrain tires.

[0003] Faced with the increasingly booming all-terrain tire market, as an internationally renowned company in this field, leading market demand, our current products still lack guidance for special terrains, as well as grip and anti-skid properties.

[0004] Therefore, a high-performance all-terrain off-road tire is still needed to solve the above problems. Utility Model Content

[0005] This invention provides a high-performance all-terrain off-road tire that solves the above-mentioned problems.

[0006] The objective of this utility model is achieved through the following technical solution: A high-performance all-terrain off-road tire includes a tread layer on which alternating herringbone patterns are formed. The herringbone patterns include a top portion located near the center of the tread layer, a connecting segment located at the bottom of the top portion, and a forked segment connected to the other side of the top portion and branching off from the connecting segment. The tips of two adjacent herringbone patterns face opposite directions; The top part is an irregular hexagonal shape, and the width of the top part increases or decreases from one end to the other. The top part has a corner at 2 / 3 of its length from one end to the other to form a first connecting segment and a second connecting segment. The angle between the first connecting segment and the tire equator is 10±3 degrees, and the angle between the second connecting segment and the tire equator is 42±3 degrees.

[0007] Preferably, the top width of the top portion is 14±2mm and the bottom width is 21±2mm.

[0008] Preferably, the connecting segment and the forked segment each have an included angle of 30±5 degrees.

[0009] Preferably, the top end, the connecting segment, and the root of the forked segment are continuous, while the top surface is discontinuous.

[0010] Preferably, the connecting segment and the forked segment are provided with connecting grooves, the depth of which is 7±2mm.

[0011] Preferably, a connecting groove is also formed on the connecting segment, which, in the rolling direction, is used to pass through the top and bottom of the connecting segment.

[0012] Preferably, the connecting segment and the forked segment also have a tail end portion corresponding to the tire shoulder, and the tail end portion is V-shaped.

[0013] Compared with the prior art, the beneficial effects of this utility model include at least the following: The tire features alternating herringbone patterns on its tread, with the herringbone treads located in the center of the tire and having apical sections. Adjacent apical sections alternate in the rolling direction of the tire, with different orientations. When the vehicle travels on soft surfaces such as mud or sand, the herringbone pattern quickly breaks through the mud and grips the ground, providing excellent traction and guidance. Furthermore, the mud embedded in the tread is squeezed out from the sides, offering excellent self-cleaning and anti-skid properties. The asymmetrical design allows for a more even distribution of tread pressure upon contact with the ground, improving grip stability by 22% compared to traditional symmetrical patterns. The front section of the apical section easily breaks through the soil and grips the ground, while the rear section has sufficient area to grip the ground, providing excellent traction while allowing mud to be smoothly expelled along the edges of the tread.

[0015] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore repeated descriptions of them will be omitted.

[0016] The terms used to describe position and direction in this utility model are illustrated with the accompanying drawings, but changes can be made as needed, and all such changes are included within the scope of protection of this utility model.

[0017] Reference Figure 1-3 This utility model provides a high-performance all-terrain off-road tire, including a tread layer 1. Alternating herringbone patterns 2 are formed on the tread layer 1. Each herringbone pattern 2 includes a top portion 3 located near the center of the tread layer 1, a connecting segment 4 located at the bottom of the top portion 3, and a forked segment 5 connected to the other side of the top portion 3 and branching off from the connecting segment 4. The top portions 3 of adjacent herringbone patterns 2 face opposite directions. The top portions 3 of the herringbone patterns 2 have two opposing orientations; in the tire's rolling direction, the herringbone patterns 2 face different left and right sides. The connecting segment 4 and the forked segment 5 are located on either side of the tire's equator, which is the tire's centerline.

[0018] The top portion 3 has an irregular hexagonal shape, and the width of the top pattern of part of the top portion 3 increases or decreases from one end to the other. The top portion 3 may include two continuous sections.

[0019] One side edge of the top portion 3 has a bend at 2 / 3 of its length from one end to the other, dividing it into a first connecting segment 6 and a second connecting segment 7. The angle between the first connecting segment 6 and the tire equator is 10±3 degrees, and the angle between the second connecting segment 7 and the tire equator is 42±3 degrees. The first connecting segment 6, divided from the hexagon, is quadrilateral, and the second connecting segment 7 is rectangular. The tread pattern at the front can easily break through soft soil surfaces and stably grip deep, firm ground. Furthermore, the rear portion has sufficient area to grip the ground, providing excellent traction while allowing soil to be smoothly expelled along the tread edges. Experimental results show that, within the aforementioned angle range for the first connecting segment 6 and within the angle range for the second connecting segment 7 relative to the equator, the tire stably grips the ground and exhibits good soil removal capabilities.

[0020] Preferably, the top width of the top portion 3 is 14±2mm, and the bottom width is 21±2mm. Referring to the figures, the top and bottom of the top portion 3 are the upper end and the middle portion at the inflection point, respectively. The closest distance between the two inclined contours is 14±2mm, and the widest point is 21±2mm. Experimental testing has shown that within the range of tire tread size, there is a gradual contact tendency with the ground, creating smooth grip friction while also having a bending contact surface effect. This prevents pressure concentration in one place, avoiding excessive tread embedment into the ground. Simultaneously, it provides stable grip while also having the ability to break through loose soil layers.

[0021] Preferably, the connecting segment 4 and the forked segment 5 each have an included angle of 30±5 degrees. The 30±5 degree angle between the two straight sections of the connecting segment 4 and the forked segment 5 provides a relatively balanced frictional force output in both the longitudinal and lateral directions, resulting in good guidance and self-cleaning performance, thus enhancing the driving experience.

[0022] Preferably, the top portion 3, the connecting segment 4, and the root of the forked segment 5 are continuous, while the top surface is discontinuous. Specifically, the top portion 3, the connecting segment 4, and the root of the forked segment 5, near the bottom of the tread, form continuous herringbone-shaped protrusions, while the top end, the connecting segment 4, and the top surface of the forked segment 5 can be discontinuous. This design ensures good rigidity while maintaining flexible guidance during grip.

[0023] Preferably, a connecting groove 8 is formed on the connecting segment 4 and the forked segment 5, and the depth of the connecting groove 8 is 7±2mm. Preferably, the connecting segment 4 and the forked segment 5 may also have a connecting groove 8, which forms a channel on the surface of the connecting segment 4 and the forked segment 5. The channel can store and quickly discharge mud. The micro-groove design can improve grip on muddy ground by 30%. On dry, hard ground, the micro-tooth structure formed by the groove can increase the coefficient of friction by 12%, improving anti-slip performance.

[0024] Preferably, a connecting groove 9 is also formed on the connecting segment 4, which extends through the top and bottom of the connecting segment 4 in the rolling direction. Providing a connecting groove 9 on the connecting segment 4 improves drainage and sludge removal performance, enhances the strength of the pattern structure, and prevents stress concentration at the bottom of the pattern from being torn apart.

[0025] Preferably, the connecting segment 4 and the forked segment 5 also have a tail end 10 corresponding to the tire shoulder, and the tail end 10 is V-shaped. The tail of the connecting segment 4 and the forked segment 5 is the end away from the equator, and the tail of the connecting segment 4 and the forked segment 5 is fishtail shaped, which can stably grip the ground on both sides of the tire, so that the tire shoulder is evenly stressed, which can improve the tire's off-road performance and also improve the tire's wear resistance by 15%.

[0026] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and alterations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention, and all such changes should fall within the protection scope of the claims of the present invention.
