Abstract
Description
Technical Field
[0001] The present application relates to the field of ATV tires and tread pattern structures, and in particular to an ATV tire and tread pattern structure. Background Art
[0002] In recent years, all-terrain vehicles (ATVs) have become increasingly popular with consumers for their superior off-road capabilities and wide applicability. Existing all-terrain tires typically utilize a traditional round inflated profile design. While this design is simple and easy to manufacture, it suffers from poor dynamic stability and insufficient shoulder traction at high speeds. The rapid growth of sport utility vehicles (SSVs), coupled with increasing power, particularly increased engine horsepower, has placed even higher demands on tire performance. To meet these high-performance demands, SSV tires utilize a high-aspect ratio tread pattern and square shoulder design, significantly improving high-speed performance and durability.
[0003] However, if the SSV square shoulder profile design and high land ratio pattern design are directly applied to ATV tires, the handling performance of the ATV vehicle will be reduced and the steering performance will be insufficient. Therefore, there is an urgent need for a new tire design that can maintain good handling performance. Utility Model Content
[0004] In order to improve the handling performance and steering performance of an all-terrain tire, the utility model provides an ATV tire and a tread pattern structure.
[0005] The utility model provides an ATV tire, which adopts the following technical solutions:
[0006] An ATV tire includes a crown and a shoulder. The crown includes a first curved surface and a second curved surface. The first curved surface is arranged across the center line of the crown. The second curved surfaces are arranged on both sides of the first curved surface. The curvature of the second curved surface is greater than that of the first curved surface. The shoulder includes a third curved surface. The curvature of the third curved surface is greater than that of the second curved surface. The ATV tire has a square shoulder profile.
[0007] By adopting this technical solution, the ATV tire features a smaller first camber on the crown, effectively improving steering performance and maneuverability. Furthermore, the gradually increasing camber from the center outward ensures stability and controllability in various driving conditions, particularly maintaining excellent grip and durability at high speeds. The larger camber on the shoulder further enhances shoulder traction, improving overall dynamic stability and driving safety.
[0008] The utility model also provides an ATV tire tread pattern structure, which adopts the following technical solutions:
[0009] A tread pattern structure of an ATV tire includes a plurality of pattern groups, wherein the plurality of pattern groups are staggeredly distributed along the circumference of the tire tread, each of the pattern groups includes a first pattern block, a second pattern block, a third pattern block, a fourth pattern block, and a fifth pattern block, wherein the first pattern block, the second pattern block, the third pattern block, the fourth pattern block, and the fifth pattern block are arranged in sequence and at intervals to form a V-shape, and the openings of the pattern groups are toward the shoulders close to the groups.
[0010] By adopting these technical solutions, the V-shaped tread design ensures excellent grip in all driving conditions, especially on slippery surfaces, effectively improving traction. Furthermore, the optimized tread arrangement reduces rolling resistance while maintaining traction, thereby improving the vehicle's fuel economy and driving efficiency. The tread openings are oriented toward the shoulder, providing better lateral support during cornering, enhancing vehicle handling stability and driving experience.
[0011] Preferably, the third pattern block is arranged close to the center line of the crown, the second pattern block and the fourth pattern block are both located on the first circle d1, the first pattern block and the fifth pattern block are located on the second circle d2, the axis of the first circle d1 and the axis of the second circle d2 both coincide with the axis of the tire, and the second circle d2 is located on the shoulder.
[0012] By adopting the above technical solution, the layout of the pattern group can effectively reduce tread stiffness, thereby improving ride comfort. Specifically, the third pattern block is located close to the crown centerline, making the pattern group distribution more dense in the crown area, increasing traction and grip in this area. At the same time, the second and fourth pattern blocks are both located on the first circle, and the first and fifth pattern blocks are located on the second circle. This unique circumferential distribution design allows the pattern blocks to evenly distribute pressure when subjected to force, reducing local stress concentration and thus reducing overall tread stiffness. In addition, the design of the second circle on the shoulder further enhances the support and stability of the shoulder, improving handling performance during high-speed driving and cornering. In summary, this design not only improves the tire's traction and high-speed performance, but also significantly improves ride comfort.
[0013] Preferably, the line connecting the first pattern block and the second pattern block is a first straight line a, and the angle α between the first straight line a and the center line of the crown is 50 degrees to 80 degrees;
[0014] The connecting line between the second pattern block and the third pattern block is a second straight line b, and the angle β between the second straight line b and the center line of the crown is 35 degrees to 65 degrees;
[0015] The line connecting the fourth pattern block and the fifth pattern block is a third straight line c, and the angle γ between the third straight line c and the center line of the crown is 50 degrees to 80 degrees;
[0016] The second straight line b and the first straight line a have an inclination direction opposite to each other, and the included angle β is smaller than the included angle α. The third straight line c and the first straight line a have an inclination direction identical to each other, and the included angle α is smaller than the included angle γ.
[0017] By employing the above technical solution, the angles of each tread block within the tread group are carefully designed to ensure high performance under various driving conditions. Specifically, the angle α between the first line a and the crown centerline is set at 50 to 80 degrees, creating a larger angle between the first and second tread blocks, which helps improve the tire's traction, especially on soft surfaces. The angle β between the second line b and the crown centerline is set at 35 to 65 degrees. The second line b is tilted in the opposite direction to the first line a, and the angle β is smaller than the angle α. This design effectively distributes pressure during driving, reducing rolling resistance while maintaining excellent grip and handling. The angle γ between the third line c and the crown centerline is also set at 50 to 80 degrees. The first and third lines a and c have the same inclination, and the angle α is smaller than the angle γ. This further enhances the tire's stability and handling at high speeds, while also improving its overall durability.
[0018] Preferably, edges of the first pattern block, the second pattern block, the fourth pattern block and the fifth pattern block are all provided with stepped portions, and the stepped portions include multiple layers of steps.
[0019] By adopting this technical solution, the stepped portion increases the effective contact area of the tread blocks, improving shoulder traction while also enhancing the rigidity and wear resistance of the tread blocks, further improving the tire's grip and durability in complex road conditions. The multi-layered step design also effectively disperses pressure, reducing wear caused by uneven force on the tread blocks and extending tire life.
[0020] Preferably, the line connecting the first pattern block and the first pattern block of the adjacent upper group is parallel to the tire axis, and the maximum length of the line connecting two first pattern blocks parallel to the tire axis is h1; the line connecting the fifth pattern block and the fifth pattern block of the adjacent lower group is parallel to the tire axis, and the maximum length of the line connecting two fifth pattern blocks parallel to the tire axis is h2, and h2 is greater than h1.
[0021] By adopting this technical solution, the first and fifth tread blocks are evenly distributed during the tire's rolling motion, improving the tire's overall stability and grip. Furthermore, the larger spacing between the two first tread blocks and the smaller spacing between the two fifth tread blocks provide different contact areas. When the ground is uneven, the larger spacing between the two first tread blocks and the smaller spacing between the two fifth tread blocks increase the likelihood of contact, thereby providing better traction and handling performance under various road conditions.
[0022] Preferably, grooves are formed on the first pattern block, the second pattern block, the third pattern block, the fourth pattern block and the fifth pattern block.
[0023] By adopting this technical solution, the grooves effectively improve the tire's drainage and anti-skid properties, enhancing wet grip and ensuring safe driving on slippery roads. Furthermore, the groove design improves the tire's heat dissipation, extending its service life and reducing performance degradation caused by elevated temperatures during driving.
[0024] In summary, the present invention has the following beneficial effects:
[0025] 1. The ATV tire's crown features a small first-arc surface, effectively improving steering performance and maneuverability. Furthermore, the gradually increasing arc from the center of the tire ensures stability and controllability under varying driving conditions, particularly maintaining excellent grip and durability at high speeds. The large arc design of the shoulder further enhances shoulder traction, improving overall dynamic stability and driving safety.
[0026] 2. The V-shaped tread design ensures excellent grip in all driving conditions, especially on slippery surfaces, effectively improving traction. The optimized tread arrangement reduces rolling resistance while maintaining traction, thereby improving fuel economy and driving efficiency. The tread openings are oriented toward the shoulder, providing better lateral support during cornering, enhancing vehicle handling stability and driving experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Example 1
[0039] An ATV tire, referring to Figure 1, comprising a crown 1 and a shoulder 2. The crown 1 includes a first curved surface 11 and a second curved surface 12. The first curved surface 11 is arranged across the centerline of the crown 1, with the second curved surface 12 provided on both sides of the first curved surface 11. The curvature of the first curved surface 11 is smaller than that of the second curved surface 12. The shoulder 2 includes a third curved surface 21, the curvature of the third curved surface 21 being greater than that of the second curved surface 12. The ATV tire has a square shoulder profile.
[0040] The crown 1 of this ATV tire features a first curved surface 11 with a relatively small radius, effectively improving steering performance and maneuverability. Furthermore, the gradually increasing radius from the center of the tire outward ensures the tire's stability and maneuverability under various driving conditions, especially maintaining good grip and durability at high speeds. The large radius of the shoulder 2 further enhances the tire's traction, improving overall dynamic stability and driving safety. ATV tire with square shoulders
[0041] Example 2
[0042] A tread pattern structure of an ATV tire, referring to Figure 2 and Figure 3 The tire comprises a plurality of pattern groups, each of which is staggered along the circumference of the tire's tread and fixedly connected to the tire. Each pattern group includes a first pattern block 3, a second pattern block 4, a third pattern block 5, a fourth pattern block 6, and a fifth pattern block 7. The first pattern block 3, the second pattern block 4, the third pattern block 5, the fourth pattern block 6, and the fifth pattern block 7 are arranged in sequence and form a V-shape, with the opening of the pattern group facing the shoulder 2 adjacent to the pattern group.
[0043] The V-shaped tread group design ensures excellent grip in all driving conditions, especially on slippery surfaces, effectively improving traction. The optimized tread group arrangement reduces rolling resistance while maintaining traction, thereby improving fuel economy and driving efficiency. The tread group openings face the shoulder 2, providing better lateral support during cornering, enhancing vehicle handling stability and driving experience.
[0044] Reference Figure 4 The third tread block 5 is positioned near the centerline of the crown 1, the second and fourth tread blocks 4 and 6 are located on a first circle d1, and the first and fifth tread blocks 3 and 7 are located on a second circle d2. The axes of the first and second circles d1 and d2 coincide with the tire axis, and the second circle d2 is located on the shoulder 2. This layout of the tread groups effectively reduces tread stiffness, thereby improving ride comfort.
[0045] Reference Figure 3The first pattern block 3, the second pattern block 4, and the third pattern block 5 form a first group. A first connecting block is provided between the first group and the tire tread. The first pattern block 3, the second pattern block 4, and the third pattern block 5 are all fixedly connected to the top of the first connecting block, and the bottom of the first connecting block is fixedly connected to the tire tread. The orientation of the first connecting block matches the orientation of the first pattern block 3, the second pattern block 4, and the third pattern block 5.
[0046] Reference Figure 3 The fourth and fifth tread blocks 6 and 7 form a second group. A second connecting block is provided between the second group and the tire tread. The fourth and fifth tread blocks 6 and 7 are both fixedly connected to the top of the second connecting block, while the bottom of the second connecting block is fixedly connected to the tire tread. The orientation of the second connecting block matches that of the fourth and fifth tread blocks 6 and 7.
[0047] Reference Figure 5 The line connecting the first tread block 3 and the second tread block 4 is a first straight line a, and the angle α between the first straight line a and the centerline of the crown 1 is 50 to 80 degrees. The line connecting the second tread block 4 and the third tread block 5 is a second straight line b, and the angle β between the second straight line b and the centerline of the crown 1 is 35 to 65 degrees. The second straight line b and the first straight line a are inclined in opposite directions, and the angle β is smaller than the angle α.
[0048] The angle α between the first straight line a and the centerline of the crown 1 is set between 50 and 80 degrees, creating a larger inclination between the first and second tread blocks 3 and 4. This helps improve the tire's traction, especially on soft surfaces. The design of angle β being smaller than angle α effectively disperses tire pressure distribution during driving, reducing rolling resistance while maintaining good grip and handling.
[0049] Reference Figure 5 The line connecting the fourth tread block 6 and the fifth tread block 7 is a third straight line c, and the angle γ between the third straight line c and the centerline of the crown 1 is 50 to 80 degrees. The third straight line c and the first straight line a have the same inclination direction, and the angle α is smaller than the angle γ.
[0050] The first straight line a and the third straight line c have the same inclination direction, and the included angle α is smaller than the included angle γ, which further enhances the stability and handling performance of the tire when traveling at high speeds, while improving the overall durability of the tire.
[0051] Reference Figure 6The line connecting a first tread block 3 and its adjacent group of first tread blocks 3 is parallel to the tire axis, and the maximum length of a line connecting two first tread blocks 3 parallel to the tire axis is h1. The line connecting a fifth tread block 7 and its adjacent group of fifth tread blocks 7 is parallel to the tire axis, and the maximum length of a line connecting two fifth tread blocks 7 parallel to the tire axis is h2. Where h2 is greater than h1.
[0052] The larger spacing between the two first tread blocks 3 and the smaller spacing between the two fifth tread blocks 7 can provide different contact areas. When the ground is in contact, due to the unevenness of the ground, the larger spacing between the two first tread blocks 3 and the smaller spacing between the two fifth tread blocks 7 can more likely contact the ground, thereby providing better traction and handling performance under different road conditions.
[0053] Reference Figure 2 and Figure 3 The edges of the first pattern block 3, the second pattern block 4, the fourth pattern block 6 and the fifth pattern block 7 are all provided with a stepped portion 9, and the stepped portion 9 includes multiple layers of steps. In this embodiment, the stepped portion 9 is provided with three layers of steps.
[0054] The stepped portion 9 increases the effective contact area of the tread blocks, enhancing the traction performance of the shoulder 2 while also increasing the rigidity and wear resistance of the tread blocks, further improving the tire's grip and durability in complex road conditions. The multi-layered step design also effectively distributes pressure, reducing wear caused by uneven force on the tread blocks and extending the tire's service life.
[0055] Reference Figure 3 Grooves 8 are provided on the first pattern block 3 , the second pattern block 4 , the third pattern block 5 , the fourth pattern block 6 and the fifth pattern block 7 .
[0056] Grooves 8 effectively improve the tire's drainage and anti-skid properties, enhancing wet grip and ensuring safe driving on slippery roads. Furthermore, the design of grooves 8 improves the tire's heat dissipation, extending its service life and reducing performance degradation caused by elevated temperatures during driving.
[0057] The principle behind this application is as follows: The V-shaped tread design ensures excellent grip under various driving conditions, particularly on slippery surfaces, effectively improving traction. Furthermore, the optimized tread arrangement reduces rolling resistance while maintaining traction, thereby improving the vehicle's fuel economy and driving efficiency. The tread openings face the shoulder 2, providing enhanced lateral support during cornering, improving the vehicle's handling stability and driving experience.
[0058] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
