Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a wheel tread pattern suitable for special multi-purpose high-speed vehicles. Background Technology

[0002] In high-speed, multi-purpose use of special vehicles, the shape of the tire's contact patch is the core of its design, and it must be matched to the specific vehicle model's high-speed, multi-purpose driving scenarios. Traditional high-speed tire treads focus on wet drainage and anti-uniform wear, but at high speeds, excessive speed can cause localized overheating of the tread, leading to the risk of tire blowout. In addition, uneven contact patch pressure distribution and airflow disturbances at high speeds can easily cause a decrease in grip, potentially resulting in safety accidents. Utility Model Content

[0003] To address the problems of localized overheating of the tread, uneven distribution of ground pressure, and reduced grip caused by excessive speed in traditional tires, this utility model provides a wheel tread pattern suitable for special multi-purpose high-speed vehicles.

[0004] The technical solution of this utility model is as follows: A tire tread block assembly, wherein the axis of the tread block assembly is a broken line, the broken line is centrally symmetrical, the geometric center of the broken line is O, one half of the broken line is nearly Z-shaped, and the other half of the broken line is rotated symmetrically about the geometric center O to obtain the other half of the broken line, which is formed by connecting line segments AB, BC, CD, DE, and EF in sequence to form a broken line ABCDEF; the tread block assembly consists of a first tread block, a second tread block, a third tread block, a fourth tread block, and a fifth tread block from one end of the broken line ABCDEF to the other end; wherein the first tread block is located at the inflection point B of the broken line ABCDEF, and the second tread block is located at the inflection point A of the broken line. At the inflection point C of line BCDEF, the third tread block is located at the geometric center O of line ABCDEF, the fourth tread block is located at the inflection point D of line ABCDEF, and the fifth tread block is located at the inflection point E of line ABCDEF. The geometric center P of the third tread block coincides with the geometric center O of line ABCDEF. The second and fourth tread blocks are rotationally symmetrical about the geometric center P. The first tread block extends to the edge of the tire shoulder and bends downward to form the side of the first tread block. The fifth tread block extends to the inside of the edge of the tire shoulder and bends downward to form the side of the fifth tread block. After rotating 180° about the geometric center P, the fifth tread block partially overlaps with the first tread block. The first, second, third, fourth, and fifth tread blocks are collectively referred to as tread blocks. Adjacent tread blocks in the same tread block group are connected by reinforcing ribs.

[0005] The third patterned block is rectangular. The line segments uv, vw, wx, and xu of the rectangle are connected sequentially to form rectangle uvwx. The four corners of rectangle uvwx are rounded outward angles. The fourth patterned block forms a hexagon with two line segments extending from the inflection point D of the broken line ABCDEF as its axis. The line segments gh, hi, ij, jk, kl, and lg of the hexagon are connected sequentially to form hexagon ghijkl. The angles ∠g, ∠h, ∠i, ∠j, and ∠k of hexagon ghijkl are rounded outward angles. The angle ∠l of hexagon ghijkl is an inward arc angle, and the angle β between line segment hi and the horizontal direction is 45°<β≤90°; the fifth pattern block forms a pentagon with two line segments extending from the inflection point E of the broken line ABCDEF as the axis. The line segments mn, nr, rs, st and tm of the pentagon are connected in sequence to form pentagon mnrstm. The angles ∠t, ∠m, ∠n, ∠s and ∠r of pentagon mnrstm are outward arc angles, and the angle α between line segment tm and the horizontal direction is 45°<α≤90°.

[0006] The fifth tread block extends to the inner side of the tire shoulder edge line, and the length from the inner side of the tire shoulder edge line to the tire shoulder edge line is 6-14mm.

[0007] The angle between line segment CD of the broken line ABCDEF and the vertical direction is 30°-40°; the angle between line segment BC and line segment DE of the broken line ABCDEF and the vertical direction is 45°-55°; the angle between line segment AB and line segment EF of the broken line ABCDEF and the tire shoulder edge line is 85°-95°.

[0008] The ratio of the surface area of ​​the third patterned block to the total surface area of ​​the patterned blocks in the same patterned block group is 16%-20%.

[0009] The patterned blocks in the patterned block group all have the same thickness, and the thickness of the reinforcing rib is 1 / 3 to 1 / 2 of the thickness of the patterned blocks in the patterned block group.

[0010] A tire tread pattern suitable for special multi-purpose high-speed vehicles includes a tread pattern, wherein the tread pattern is formed by the above-mentioned tread block groups evenly distributed along the circumference of the tire, and the tread block groups form transverse tread grooves between the tread block groups; adjacent tread block groups are centrally symmetrical.

[0011] The width of the lateral tread grooves gradually increases from the center line of the tread to the two shoulders.

[0012] The width of the transverse groove between the first and fifth patterned blocks in the adjacent patterned block group is w3, the width of the transverse groove between the second and fourth patterned blocks in the adjacent patterned block group is w2, and the width of the transverse groove between the third patterned blocks in the adjacent patterned block group is w1, wherein 1 / 3w3≤w1≤w3, w1<w2<w3.

[0013] The side of the fifth patterned block is tangent to the bottom of the transverse patterned groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By combining the arrangement of the tread blocks in the tread block group with the design of the angle and size of the tread blocks, heat dissipation at the bottom of the tire is ensured during high-speed driving, thus improving high-speed performance. At the same time, it ensures the ground contact stability of the middle tread block (i.e., the third tread block) during highway driving, while ensuring the grip and climbing performance of the shoulder on off-road and muddy surfaces. This makes the tire provided by this utility model suitable for special multi-purpose high-speed vehicles, ensuring improved tire grip, high-speed performance, and air permeability under multi-purpose (mud, off-road, water, highway) high-speed driving, thus ensuring driving safety.

Detailed Implementation

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the implementation of this utility model, not all of it. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] In this invention, the default direction of wheel travel is... Figure 1 The direction indicated by the middle arrow is forward, and the direction away from it is backward.

[0023] The center line of the tire tread is the line located in the middle of the tire tread along the circumference.

[0024] like Figure 1-2 As shown, a tire pattern suitable for special multi-purpose high-speed vehicles includes a tread pattern, wherein the tread pattern is formed by tread block groups 1 evenly distributed along the circumference of the tire, and transverse tread grooves 7 are formed between the tread block groups 1; adjacent tread block groups 1 are centrally symmetrical.

[0025] Adjacent tread block groups 1 are centrally symmetrical, that is, the tread block groups are evenly distributed along the tire circumference with a rotation center P1 rotated 180° around the rotation center P1, and the rotation center P1 is located on the center line of the tire tread.

[0026] The axis of the pattern block group 1 is a broken line, which is centrally symmetrical. The geometric center of the broken line is O. One half of the broken line is rotated symmetrically about the geometric center O to obtain the other half, which is formed by connecting line segments AB, BC, CD, DE, and EF in sequence to form the broken line ABCDEF. The pattern block group 1 consists of a first pattern block 2, a second pattern block 3, a third pattern block 4, a fourth pattern block 5, and a fifth pattern block 6 from one end of the broken line ABCDEF to the other. Among them, the first pattern block 2 is located at the inflection point B of the broken line ABCDEF, the second pattern block 3 is located at the inflection point C of the broken line ABCDEF, the third pattern block 6 is located at the inflection point C of the broken line ABCDEF, and the fifth pattern block 6 is located at the inflection point C of the broken line ABCDEF. Block 4 is located at the geometric center O of the broken line ABCDEF, the fourth tread block 5 is located at the inflection point D of the broken line ABCDEF, and the fifth tread block 6 is located at the inflection point E of the broken line ABCDEF; the geometric center P of the third tread block 4 coincides with the geometric center O of the broken line ABCDEF; the second tread block 3 and the fourth tread block 5 are 180° rotationally symmetrical about the geometric center P; the first tread block 2 extends to the tire shoulder edge line 10 and bends downward to form the side of the first tread block 2; the fifth tread block 6 extends to the inner side of the tire shoulder edge line 10 and bends downward to form the side 61 of the fifth tread block; after rotating 180° about the geometric center P, the fifth tread block 6 partially overlaps with the first tread block 2; adjacent tread blocks in the same tread block group 1 are connected by reinforcing ribs; this arrangement makes the fifth tread block concave relative to the adjacent first tread block, allowing air to enter the bottom of the tread groove and accelerating heat dissipation from the tire tread.

[0027] In this utility model, the axis is not defined by the angle bisector, but by the perpendicular line; the first pattern block 2, the second pattern block 3, the third pattern block 4, the fourth pattern block 5, and the fifth pattern block 6 are collectively referred to as pattern blocks.

[0028] The third pattern block 4 is a rectangle, and the line segments uv, vw, wx, and xu of the rectangle are connected in sequence to form rectangle uvwx; the four corners of rectangle uvwx are rounded outward corners; the fourth pattern block 5 forms a hexagon with the two line segments extending from the inflection point D of the broken line ABCDEF as the axis, and the line segments gh, hi, ij, jk, kl, and lg of the hexagon are connected in sequence to form hexagon ghijkl, and the corners ∠g, ∠h, ∠i, ∠j, and ∠k of hexagon ghijkl are rounded outward corners. The angle ∠l of hexagon ghijkl is an inward arc angle, and the angle β between line segment hi and the horizontal direction is 45°<β≤90°; the fifth pattern block 6 forms a pentagon with two line segments extending from the inflection point E of the broken line ABCDEF as the axis. The line segments mn, nr, rs, st and tm of the pentagon are connected in sequence to form pentagon mnrstm. The angles ∠t, ∠m, ∠n, ∠s and ∠r of pentagon mnrstm are outward arc angles, and the angle α between line segment tm and the horizontal direction is 45°<α≤90°.

[0029] In this design, when the fifth tread block 6 contacts the ground first, that is, the line segment tm of pentagon mnrstm that first contacts the ground along the tire's direction of travel forms an angle α with the tire's axial direction. The angle α opens towards the outer side of the tire. Figure 4 As shown, when the tire is moving, the surrounding air moves in the opposite direction to the direction of travel. This reverse direction is reflected by contact with the walls of the lateral tread grooves, creating a direction. When 45° < α ≤ 90°, this direction approaches the line segment tm of the fifth tread block that first contacts the ground in the tire's circumferential direction of travel, pointing towards the center of the lateral tread groove. The angle β between the line segment hi of the fourth tread block 5 (i.e., hexagon ghijkl) that first contacts the ground in the tire's direction of travel and the tire's axial direction points towards the centerline of the tire tread. Figure 4 As shown, when the tire is moving, the surrounding air will be in the opposite direction of the forward movement. This reverse direction is reflected by contact with the wall of the lateral tread groove. When 45° < β ≤ 90°, this direction is closer to the line segment hi of the fourth tread block that first contacts the ground in the tire's circumferential direction of travel, pointing to one side of the lateral tread groove.

[0030] The distance from line segment wx of rectangle uvwx to the geometric center O of the polygon is greater than the distance from line segment ij of hexagon ghijkl to the inflection point D of the polygon; the distance from line segment ij of hexagon ghijkl to the inflection point D of the polygon is less than the distance from line segment hi of hexagon ghijkl to the inflection point D of the polygon; the distance from line segment hi of hexagon ghijkl to the inflection point D of the polygon is less than the distance from line segment nr of pentagon mnrstm to the inflection point E of the polygon.

[0031] The fifth tread block 6 extends to the inner side of the tire shoulder edge line, and the length from the inner side of the tire shoulder edge line to the tire shoulder edge line 10 is 6-14mm.

[0032] The angle between line segment CD of the broken line ABCDEF and the vertical direction is 30°-40°; the angle between line segment BC and line segment DE of the broken line ABCDEF and the vertical direction is 45°-55°; the angle between line segment AB and line segment EF of the broken line ABCDEF and the tire shoulder edge line 10 is 85°-95°.

[0033] The ratio of the surface area of ​​the third tread block 4 to the total surface area of ​​the tread blocks in the same tread block group is 16%-20%. If the ratio is too high, heat will easily accumulate in the middle of the tire at high speeds, causing thermal damage. If the ratio is too low, the surface area of ​​the tread blocks will be small. The middle of the tire surface is the part with the largest tire circumference and bears the greatest pressure. If the surface area of ​​the tread blocks is small, the specific pressure per unit area will be larger, resulting in insufficient rigidity. This will lead to the tread blocks falling off in off-road conditions. This ratio setting can meet the requirements of rigidity and high speed.

[0034] The width of the transverse tread groove 7 gradually increases from the center line of the tread to the two sides of the tire shoulder.

[0035] The width of the lateral groove 7 between the first tread block 2 and the fifth tread block 6 of the adjacent tread block group 1 is w3, the width of the lateral groove 7 between the second tread block 3 and the fourth tread block 5 of the adjacent tread block group 1 is w2, and the width of the lateral groove 7 between the third tread block 4 of the adjacent tread block group 1 is w1, wherein 1 / 3w3≤w1≤w3, w1<w2<w3; the lateral grooves are wider at the tire shoulder, where more air is received. Combined with the airflow design, whether the tire is moving forward or backward, and considering the angle at which the tread block first contacts the edge of the ground, airflow occurs on both sides of the lateral groove, thus ensuring heat dissipation at the bottom of the tire during high-speed driving and improving high-speed performance; at the same time, the gradual width design of the lateral grooves ensures the ground contact stability of the third tread block during highway driving, while ensuring the grip and climbing performance of the shoulder on off-road surfaces, muddy surfaces, etc.

[0036] The tread blocks in the tread block group are all the same thickness, and the thickness of the reinforcing rib 9 is 1 / 3 to 1 / 2 of the thickness of the tread blocks in the tread block group; this ensures the continuity between adjacent tread block groups. If the thickness of the reinforcing rib is too high, the gas flow between the transverse tread grooves will be weakened. Since the transverse tread grooves gradually widen from the center line of the tread to the two sides of the tire shoulder, if the thickness of the reinforcing rib is too low, it will affect the gas flow of a single transverse tread groove.

[0037] like Figure 3As shown, the side 61 of the fifth tread block is tangent to the bottom of the transverse tread groove 7; this can prevent the tire from deforming continuously at high speeds, causing cracks, fissures, and premature damage.

[0038] In practical use, tires with different tread patterns can be used depending on the environment and situation to provide effective assistance.

[0039] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
