Description

Technical Field

[0001] This application relates to the field of tire technology, and in particular to a tire and a vehicle. Background Technology

[0002] During car driving, tire wear and load-bearing capacity are the focus of market attention. However, with the continuous development of global automotive technology and the continuous improvement of people's car concepts, the performance requirements for tires are getting higher and higher. In particular, various countries have formulated corresponding tire labeling regulations, and are paying more and more attention to tire noise, ride comfort, braking on dry and wet roads, and handling safety.

[0003] In tire design, tread pattern is a core element affecting tire performance. Depending on the vehicle's usage requirements, tire tread patterns are categorized into large and small tread blocks; symmetrical, asymmetrical, and directional patterns. Small tread blocks help reduce noise and improve ride comfort, but their grip and braking performance on both dry and wet surfaces are relatively weaker. Large tread blocks improve handling stability and braking performance, but they result in higher noise levels and a less comfortable ride.

[0004] In existing tire tread pattern designs, when improving the performance of tire tread patterns, improving one aspect of performance often restricts the improvement of other aspects. It is impossible to simultaneously improve ride comfort, maintain low noise, and improve braking performance and handling safety on dry and wet roads. Utility Model Content

The length of the arc-shaped chamfer structure is equal to the length of the stepped chamfer structure. The length of the second arc-shaped groove is less than the length of the arc-shaped chamfer structure. The third arc-shaped groove is disposed on the side of the second arc-shaped groove close to the spacer groove. The second arc-shaped groove is a closed groove.

[0010] According to some embodiments of this application, the spacer groove is provided with a plurality of sets of protruding structures, each set of protruding structures including two bosses, the two bosses being arranged opposite each other along the width direction of the tire tread and offset along the length direction of the tire tread.

[0028] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0029] Reference Figures 1 to 5 The following are specific embodiments of this application.

[0030] Depend on Figure 1 As shown, this application provides a tire whose tread structure includes 2-6 different pitches, the width of which ranges from 17mm to 46mm, and the number of which ranges from 42 to 100.

[0031] Specifically, the tread structure includes a central region and shoulder regions on both sides of the central region. The central region has a first region 100 and a second region 200, and the shoulder regions have a third region 300. The tread also has spacer grooves 400. With the first region 100 as the center, the second region 200 and the third region 300 are symmetrically arranged along the width direction of the tread. There are four spacer grooves 400, located between the first region 100, the second region 200, and the third region 300, to separate them along the width direction of the tread.

[0032] By symmetrically arranging the tread pattern around the first region 100, deformation is reduced during tire rolling, resulting in low energy consumption and helping to reduce tire rolling resistance.

[0033] The first region 100 is provided with several sets of intersecting first grooves 110 and second grooves 120. The first groove 110 has a straight structure and the second groove 120 has a Z-shaped structure. The center of the first groove 110 and the center of the second groove 120 intersect.

[0034] In some practical examples, the spacing between each set of intersecting first grooves 110 and second grooves 120 and its adjacent set of intersecting first grooves 110 and second grooves 120 ranges from 17mm to 46mm.

[0035] In some embodiments, the first groove 110 is a straight groove with a length ranging from 10mm to 40mm, a width ranging from 0.4mm to 4mm, and a depth ranging from 2mm to 12mm. The second groove 120 is a Z-shaped groove with a length ranging from 15mm to 70mm, a width ranging from 0.4mm to 4mm, and a depth ranging from 2mm to 10mm.

[0036] By cross-cutting the first groove 110 and the second groove 120, the stiffness of the first region 100 can be reduced, optimizing the stress distribution in the center region of the tread. Simultaneously, both the first groove 110 and the second groove 120 are narrow grooves with small intervals, allowing the areas between them to mutually constrain and support each other during vehicle operation. This reduces excessive deformation and vibration during rolling, improving tire comfort and reducing noise.

[0037] In some embodiments, the second region 200 includes a plurality of spaced-apart third grooves 210 and fourth grooves 220. The third grooves 210 are straight grooves, and the fourth grooves 220 have V-shaped grooves. The spacing between the third grooves 210 and the fourth grooves 220 ranges from 8mm to 30mm.

[0038] The third groove 210 and the fourth groove 220 are cut at unequal intervals. This enhances the mutual support of the tire tread when it deforms, thereby reducing excessive deformation and vibration during rolling, ensuring tire comfort and reducing noise during driving.

[0039] Depend on Figure 2 As shown, the length of the third groove 210 ranges from 4mm to 25mm, the width ranges from 0.4mm to 4mm, and the depth ranges from 2mm to 12mm.

[0040] In some embodiments, the fourth groove 220 includes a first arc-shaped groove 221 and an oblique V-shaped groove 222. There are two oblique V-shaped grooves 222, symmetrically arranged on both sides of the first arc-shaped groove 221 along the axial direction of the tire tread. The opening directions of the two oblique V-shaped grooves 222 are opposite. When the vehicle is in motion, water on the road surface is squeezed in front of the tire and, before it is discharged in time, forms a thin water film covering the area between the tire and the road surface. When the tire rolls, the oblique V-shaped grooves can quickly and effectively cut into the surface of the water film, breaking the continuity of the water and thus improving the drainage performance of the tread pattern. Simultaneously, it can increase the effective contact area of ​​the tire tread, improve grip on wet surfaces, shorten the braking distance, ensure the tire's braking performance on wet surfaces, and thus improve the overall handling performance and wear resistance of the tire.

[0041] In some embodiments, the length of the first arc-shaped groove 221 ranges from 10mm to 50mm, the width ranges from 0.4mm to 4mm, and the depth ranges from 2mm to 12mm.

[0042] The length of the inclined V-groove 222 ranges from 10mm to 50mm, the width ranges from 0mm to 3mm, and the depth ranges from 0mm to 3mm.

[0043] In some embodiments, the third region 300 includes a plurality of fifth grooves 310 and sixth grooves 320 spaced apart, wherein the fifth grooves 310 are arc-shaped grooves and the sixth grooves 320 are semi-enclosed stepped structures.

[0044] In some embodiments, the fifth groove 310 is an intermittent arc-shaped groove, specifically an "i-shape". The sixth groove 320 includes a stepped chamfer structure 321, an arc-shaped chamfer structure 323, and an arc-shaped groove. The stepped chamfer structure 321 and the arc-shaped chamfer structure 323 are provided on both sides of the arc-shaped groove along the length direction of the tread. The arc-shaped groove is a semi-closed structure, with one side opening along the width direction of the tread and connecting to the edge of the spacer groove 400, and the other side being a closed end.

[0045] Depend on Figure 3As shown, in some embodiments, the arc-shaped groove includes a second arc-shaped groove 322 and a third arc-shaped groove 324. The second arc-shaped groove 322 is located adjacent to the stepped chamfer structure 321 on one side along the length direction of the tread, and adjacent to the arc-shaped chamfer structure 323 on the other side. The length of the arc-shaped chamfer structure 323 is equal to the length of the stepped chamfer structure 321. The length of the second arc-shaped groove 322 is less than the length of the arc-shaped chamfer structure 323. The third arc-shaped groove 324 is located on the side of the second arc-shaped groove 322 near the spacer groove 400. The second arc-shaped groove 322 is a closed groove.

[0046] By using stepped chamfered structures 321 and arc-shaped chamfered structures 323 on both sides of the second arc-shaped groove 322 and the third arc-shaped groove 324 to form a semi-enclosed stepped structure, a continuous drainage channel can be formed, which can enhance the tire's drainage efficiency on wet and slippery roads. At the same time, as the tire wears down in the middle and later stages of its use, the bottom layer of the stepped chamfered structure 321 gradually touches the ground, increasing the contact area of ​​the tire tread and ensuring that the tire has good grip on dry or wet roads throughout its service life, thus ensuring driving safety.

[0047] The third arc groove 324 adopts a semi-enclosed groove design, which can effectively prevent airflow in the tire shoulder area and reduce driving noise when driving at high speeds.

[0048] In some embodiments, the length of the fifth groove 310 ranges from 15mm to 70mm, the width ranges from 0.4mm to 4mm, and the depth ranges from 1mm to 11mm.

[0049] The length of the stepped chamfered structure 321 ranges from 20mm to 80mm, the width ranges from 0mm to 4mm, and the depth ranges from 0mm to 5mm.

[0050] The length of the curved chamfer structure 323 ranges from 12mm to 80mm, the width ranges from 0.4mm to 4mm, and the depth ranges from 0mm to 5mm.

[0051] The length of the second arc-shaped groove 322 ranges from 10mm to 70mm, the width ranges from 0.8mm to 5mm, and the depth ranges from 0mm to 11mm.

[0052] The length of the third arc groove 324 ranges from 2mm to 15mm, the width ranges from 0.4mm to 4mm, and the depth ranges from 1mm to 10mm.

[0053] Depend on Figure 4 and Figure 5As shown, the width of the groove 400 ranges from 5mm to 25mm, and the depth ranges from 2mm to 12mm. The inner wall of the groove 400 is an inclined surface with an inclination angle ranging from 5° to 20°. By making the inner wall of the groove 400 a groove with an inclined angle, foreign objects such as gravel and mud embedded in the groove 400 can more easily slide out along the inclined surface during vehicle operation, effectively reducing the risk of stones getting stuck and improving the self-cleaning ability of the tire tread. At the same time, it ensures that water is quickly expelled from the tire when driving on wet roads, ensuring effective contact between the tire tread and the road surface, improving wet grip. Meanwhile, the inclined groove can provide stable lateral support stiffness under dry conditions. When turning or changing lanes, the tire tread deformation is controllable, improving steering precision and driving stability, and also improving grip performance on both dry and wet roads.

[0054] In some embodiments, the spacer groove 400 is provided with a plurality of sets of protrusions, each set of protrusions including two bosses 410, the two bosses being arranged opposite each other along the width direction of the tire tread and offset along the length direction of the tire tread.

[0055] The boss 410 can partially block the high-speed airflow within the slot 400, slowing down the airflow and thus reducing the noise generated during tire rolling.

[0056] In some embodiments, the length of the boss 410 ranges from 8mm to 40mm, the width ranges from 5mm to 25mm, and the depth ranges from 2mm to 8mm. Within a spacer slot 400, there are 5-20 sets of bosses 410, and the bosses 410 are triangular in shape.

[0057] In this application, the width direction of the tread is the axial direction of the tire, and the length direction of the tread is the circumferential direction of the tire.

[0058] This application also provides a vehicle including the aforementioned tire. The tire of this application is suitable for ordinary passenger cars, especially ride-hailing vehicles.

[0059] The tire and vehicle of this application, by symmetrically providing a second and third region on the tire tread with a first region as the center, reduce deformation during tire rolling, resulting in low energy consumption and helping to reduce rolling resistance. Simultaneously, the first region is provided with a first groove and a second groove. The first groove is a straight groove, and the second groove is a Z-shaped groove. Their intersecting arrangement provides mutual constraint and support, thereby reducing excessive deformation and vibration during rolling while lowering tread stiffness, improving tire comfort and reducing noise during driving. The second area features a fourth groove with V-shaped grooves that effectively cut into the water film surface, improving the tread's drainage performance. The third area has a sixth groove with a semi-enclosed stepped structure, forming continuous drainage channels to further enhance the tire's drainage performance in wet conditions. As the tire wears, the stepped structure gradually contacts the ground, ensuring grip during use and thus overall handling safety. Simultaneously, the semi-enclosed stepped structure of the sixth groove effectively blocks airflow on the tire tread during driving, reducing road noise. This enhances ride comfort while maintaining low noise levels and ensuring braking and handling safety in both dry and wet conditions. Finally, the spacers contain staggered protrusions that impede airflow, further reducing tread noise. This combination of improved ride comfort, low noise levels, and enhanced braking and handling safety in both dry and wet conditions further contributes to the overall improvement.
