Abstract
Description
Technical Field
[0001] This utility model relates to the field of wheel technology, and in particular to a tire tread structure, a tire, and a wheel. Background Technology
[0002] The tire tread structure directly affects the vehicle's driving safety and driving experience, and mainly includes the tire crown and tire shoulder.
[0003] The tread is the outermost part of the tire that directly contacts the ground. It is usually made of wear-resistant and aging-resistant rubber materials, with high hardness and strength to ensure the tire's wear resistance and puncture resistance. Its surface has various patterns, such as longitudinal patterns, lateral patterns, and block patterns. These patterns increase the friction between the tire and the ground, improving the vehicle's handling, braking, and water drainage performance.
[0004] The tire shoulder, located between the tire crown and the tire sidewall, serves as a connection and transition. It bears the lateral forces and a portion of the vertical load during vehicle operation, requiring a certain degree of rigidity and toughness to ensure tire stability during cornering and driving.
[0005] However, the existing tread structure design uses large block patterns or continuous grooves, which can easily generate noise and result in insufficient quietness. Insufficient rigidity in the crown area leads to poor steering response and limited maneuverability. Inappropriate groove design can easily cause the risk of slipping on wet surfaces.
[0006] Therefore, there is an urgent need for a tire tread structure, tire, and wheel to solve the above-mentioned technical problems. Utility Model Content

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0010] The central region includes a first central region and two second central regions. Along the axial direction of the wheel, the first central region is sandwiched between the two second central regions. A first straight groove is formed between the first central region and the second central regions. The first straight groove is connected end to end around the axis of the wheel. A first steel sheet is provided in the first central region, and a second steel sheet is provided in the second central region. In a projection perpendicular to the central region, the seam of the first steel sheet and the seam of the second steel sheet form a discontinuous pattern.
[0011] The tire shoulder area has two such areas. The central area is sandwiched between the two tire shoulder areas along the axial direction of the wheel. A second straight groove is formed between the central area and the tire shoulder areas. The second straight groove is connected end to end around the axis of the wheel. A drainage groove is provided through the tire shoulder area along the axial direction of the wheel.
[0012] As a preferred technical solution for the above-mentioned tire tread structure, the thickness of the first steel sheet gradually increases from the center of the first central area to the two side edges along the axial direction of the wheel.
[0013] As a preferred technical solution for the above-mentioned tire tread structure, the first central area is provided with a plurality of the above-mentioned first steel sheets, which are arranged sequentially along the circumference of the wheel. In the projection perpendicular to the central area, the joint between two adjacent first steel sheets is arc-shaped.
[0014] The aforementioned second central area is provided with a plurality of the aforementioned second steel plates, which are arranged sequentially along the circumference of the aforementioned wheel. In a projection perpendicular to the aforementioned central area, the joint between two adjacent aforementioned second steel plates includes an arc segment and a straight segment, with one end of the aforementioned straight segment intersecting with one end of the aforementioned arc segment.
[0015] As a preferred technical solution for the above-mentioned tire tread structure, the plurality of the above-mentioned first steel sheets include first steel sheet A and first steel sheet B. The first steel sheet A and the first steel sheet B are spaced apart along the axial direction of the wheel, and are arranged alternately along the axial direction of the wheel.
[0016] As a preferred technical solution for the above-mentioned tire tread structure, the angle α between the tangent of the arc segment and the straight segment is 20°≤α≤45°, and the tangent is formed at the intersection of the arc segment and the straight segment.
[0017] As a preferred technical solution of the above-mentioned tire tread structure, the two side walls of the first straight groove are inclined, and the distance between the two side walls gradually increases in the direction away from the bottom of the first straight groove.
[0018] The two side walls of the second straight groove are inclined, and the distance between the two side walls gradually increases in the direction away from the bottom of the second straight groove.
[0019] As a preferred technical solution for the above-mentioned tire tread structure, the inclination angle between the sidewall of the first straight groove and its bottom is between 95° and 115°.
[0020] The inclination angle between the sidewall of the second straight groove and its bottom is between 95° and 115°.
[0021] As a preferred technical solution of the above-mentioned tire tread structure, the drainage groove includes a first groove and a second groove. In the axial direction of the wheel, one end of the first groove is connected to the second straight groove and the other end is closed. One end of the second groove intersects with the first groove and the other end of the second groove passes through the tire shoulder area.
[0022] A tire is also provided, including the tire tread structure described above.
[0023] A wheel is also provided, comprising a hub and the aforementioned tire, wherein the tire is fitted over the hub.
[0024] The beneficial effects of this utility model are:
[0025] This utility model provides a tire tread structure, including a central region and shoulder regions. The central region includes a first central area and two second central areas. Along the wheel's axial direction, the first central area is sandwiched between the two second central areas, forming a first straight groove between them. This first straight groove connects end-to-end around the wheel's axis. A first steel sheet is disposed in the first central area, and a second steel sheet is disposed in each of the second central areas. Projected perpendicular to the central region, the seams of the first and second steel sheets form a discontinuous tread pattern. Two shoulder regions are provided, along the wheel's axial direction, with the central region sandwiched between them. A second straight groove is formed between the central region and the shoulder regions, connecting end-to-end around the wheel's axis. A drainage groove is provided through the shoulder regions along the wheel's axial direction.
[0026] For example, along the wheel's axial direction, a central region is sandwiched between two tire shoulder regions, and this central region is the main contact area between the tire tread and the ground. The central region forms a first central area and two second central areas, with the first central area sandwiched between the two second central areas. A second straight groove separates the second central areas from the tire shoulder regions, and a first straight groove separates the second central areas from the first central area. Thus, both the first and second central areas form concentric rings with the wheel, creating reinforcing ribs that enhance tire rigidity and improve steering response. Furthermore, a first steel sheet is provided in the first central area, and a second steel sheet is provided in the second central area. Projected perpendicular to the central area, the seams of the first and second steel sheets form a discontinuous pattern, which disperses noise frequencies and improves noise reduction. Moreover, since drainage grooves are provided in the tire shoulder regions, water accumulated in the second straight grooves can be promptly drained along these grooves to both sides of the tire.
[0027] Thus, the tread structure has the characteristics of high rigidity and strength, good noise performance and high drainage efficiency, and achieves structural compatibility. Attached Figure Description

[0044] like Figures 1 to 4 As shown, this utility model provides a tire tread structure, including a central region 100 and a shoulder region 400. The central region 100 includes a first central region 110 and two second central regions 120. Along the wheel's axial direction X, the first central region 110 is sandwiched between the two second central regions 120. A first straight groove 130 is formed between the first central region 110 and the second central regions 120, and the first straight groove 130 is connected end-to-end around the wheel's axis. A first steel sheet 200 is provided in the first central region 110, and a second steel sheet 300 is provided in the second central region 120. In a projection perpendicular to the central region 100, the seams of the first steel sheet 200 and the second steel sheet 300 form a discontinuous pattern. Two shoulder regions 400 are provided. Along the wheel's axial direction X, the central region 100 is sandwiched between the two shoulder regions 400. A second straight groove 500 is formed between the central region 100 and the shoulder regions 400, and the second straight groove 500 is connected end-to-end around the wheel's axis. A drainage groove 410 is provided through the shoulder regions 400 along the wheel's axial direction X.
[0045] For example, along the wheel's axial direction X, a central region 100 is sandwiched between two shoulder regions 400, and the central region 100 is the main contact area between the tire tread and the ground. The central region 100 forms a first central region 110 and two second central regions 120. The first central region 110 is sandwiched between the two second central regions 120. A second straight groove 500 is spaced between the second central regions 120 and the shoulder regions 400, and a first straight groove 130 is spaced between the second central regions 120 and the first central region 110. Thus, both the first central region 110 and the second central regions 120 form concentric rings with the wheel, and the first central region 110 and the second central regions 120 form reinforcing ribs, thereby enhancing the tire's rigidity and improving steering response speed. Furthermore, a first steel sheet 200 is provided in the first central area 110, and a second steel sheet 300 is provided in the second central area 120. Projected perpendicular to the central area 100, the seams of the first steel sheet 200 and the second steel sheet 300 form a discontinuous pattern, thus dispersing the generated noise frequency and improving noise reduction. Furthermore, since a drainage groove 410 is provided in the tire shoulder area 400, water accumulated in the second straight groove 500 can be promptly discharged along the drainage groove 410 to both sides of the tire.
[0046] Thus, the tread structure has the characteristics of high rigidity and strength, good noise performance and high drainage efficiency, and achieves structural compatibility.
[0047] Specifically, regarding the wheel's axial direction X, the dimensions of both the first central area 110 and the second central area 120 are between 8mm and 28mm.
[0048] Specifically, regarding the wheel's axial direction X, the dimensions of the first straight groove 130 and the second straight groove 500 are both between 3mm and 18mm.
[0049] Optionally, along the axial direction X of the wheel, from the center of the first central region 110 to the two side edges, the thickness of the first steel sheet 200 gradually increases.
[0050] In this way, an arc can be formed in the first central area 110, optimizing the distribution of ground pressure and improving driving comfort.
[0051] Specifically, the first steel sheet 200 gradually thickens from the center of the first central area 110 to both sides by 1.5mm to 5mm.
[0052] Specifically, the radius of curvature of the arc formed by the first central area 110 is 100mm-2600mm.
[0053] Optionally, the first central area 110 is provided with a plurality of first steel plates 200, which are arranged sequentially along the circumference of the wheel. In the projection perpendicular to the central area 100, the joint between two adjacent first steel plates 200 is arc-shaped. The second central area 120 is provided with a plurality of second steel plates 300, which are arranged sequentially along the circumference of the wheel. In the projection perpendicular to the central area 100, the projection of two adjacent second steel plates 300 includes an arc segment 310 and a straight segment 320, with one end of the straight segment 320 intersecting one end of the arc segment 310.
[0054] With this configuration, the seams of the first steel sheet 200 and the second steel sheet 300 form a discontinuous pattern, which can disperse the generated noise frequencies and improve the noise reduction effect.
[0055] Optionally, the plurality of first steel plates 200 include first steel plate A210 and first steel plate B220. In the axial direction X of the wheel, the first steel plate A210 and the first steel plate B220 are spaced apart, and in the axial direction X of the wheel, the first steel plate A210 and the first steel plate B220 are staggered.
[0056] For example, a first seam A is formed between two adjacent first steel plates A210, and a first seam B is formed between two adjacent first steel plates B220. Along the axial direction X of the wheel, one end of the first seam A is connected to the first straight groove 130, and the other end points to the centerline of the first central area 110. One end of the first seam B is connected to another first straight groove 130, and the other end of the first seam B points to the centerline of the first central area 110.
[0057] Optionally, the angle α between the tangent of arc segment 310 and line segment 320 is 20°≤α≤45°, and the tangent is formed at the intersection of arc segment 310 and line segment 320.
[0058] Optionally, the two side walls of the first straight groove 130 are inclined, and the distance between the two side walls gradually increases in the direction away from the bottom of the first straight groove 130; the two side walls of the second straight groove 500 are inclined, and the distance between the two side walls gradually increases in the direction away from the bottom of the second straight groove 500.
[0059] This facilitates drainage and prevents stones from getting stuck in the first straight channel 130 and the second straight channel 500.
[0060] Specifically, the inclination angle between the sidewall of the first straight groove 130 and its bottom is between 95° and 115°; the inclination angle between the sidewall of the second straight groove 500 and its bottom is between 95° and 115°.
[0061] Optionally, the drainage groove 410 includes a first groove 411 and a second groove 412 along the axial direction X of the wheel. One end of the first groove 411 is connected to the second straight groove 500 and the other end is closed. One end of the second groove 412 intersects with the first groove 411 and the other end of the second groove 412 passes through the tire shoulder area 400.
[0062] For example, the drainage channel 410 is H-shaped, including a first channel 411 and a second channel 412. The first channel 411 and the second channel 412 intersect but do not overlap. This arrangement can balance drainage performance and noise reduction performance.
[0063] Specifically, the width of the first groove 411 is between 0.5 mm and 4 mm. The width of the second groove 412 is between 1 mm and 5 mm.
[0064] This utility model also provides a tire, including the tire tread structure described above.
[0065] This utility model also provides a wheel, including a hub and the aforementioned tire, with the tire fitted over the hub. Furthermore, the above are merely preferred embodiments and the technical principles employed in this utility model. Those skilled in the art will understand that this utility model is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of this utility model. Therefore, although the utility model has been described in detail through the above embodiments, this utility model is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of this utility model, the scope of which is determined by the scope of the appended claims.
