Description

Technical Field

[0001] This utility model relates to tread block decoration, and more particularly to tire tread block decoration, as well as tread blocks and tires containing the same, and especially to tires for mining machinery. Background Technology

[0002] Mining machinery, especially large mining machinery, requires tires with large tread blocks to ensure their massive load capacity. This reduces stress on the tread blocks, prevents premature wear and severe cutting, and extends tire life. However, in rainy, muddy, and heavily loaded uphill / downhill conditions, if too much of the tread block area is in contact with the ground, the corresponding area and width of the non-tread portion (the tread grooves) are reduced. This results in unadorned tread blocks and a lack of tread decoration, making it more difficult to effectively transfer traction and braking force to the ground, leading to tire slippage. Furthermore, a large tire height and large tread block volume, without any grooves or tread decoration, makes the tire appear aesthetically unappealing. Utility Model Content

[0003] To address the aforementioned issues, this utility model provides a tire tread block decoration, as well as a tread block and tire containing the decoration. In rainy, muddy, and heavily loaded uphill / downhill environments, it not only ensures the tire's traction and braking force but also further improves the tire's wear resistance and cut resistance. Because the tread block decoration is formed by intersecting strip-shaped protrusions in different directions, these protrusions reflect light in different directions, increasing the brightness of the tread block decoration. This creates a brightness difference between the tread block decoration and the surrounding non-protruding parts of the tread block, making the protrusion more conspicuous and providing these tires with a high-end appearance.

[0004] The technical solution of this utility model is as follows: a pattern block decoration, which is a protrusion provided on the surface of the pattern block, the protrusion being a height of more than 0.1mm and less than 1.2mm protruding from the surface of the tire pattern block in the normal direction; the pattern block decoration is a first pattern block decoration and / or a second pattern block decoration;

[0005] The first decorative pattern includes a first pattern and a second pattern; the first pattern is a zigzag strip protrusion I, the width of which is 2mm-20mm; the second pattern consists of at least two protrusions with closed outer contours, the distance between the centers of two adjacent protrusions with closed outer contours is 1-5 / 3 times the width of the zigzag strip protrusion I; the second pattern is inside the first pattern.

[0006] The second decorative pattern includes the third and fourth patterns; the third pattern is a zigzag strip-shaped protrusion II with a width of 2mm-20mm; the fourth pattern is a zigzag strip-shaped protrusion III with a width of 2mm-20mm; the third and fourth patterns are connected.

[0007] The zigzag-shaped strip protrusion I includes strip protrusions I, II, III, IV, V, VI, and VII connected in sequence.

The outer contour of the protrusion is a closed figure, which can be a circle, triangle, quadrilateral, or pentagon.

[0008] The angle α between the strip-shaped protrusion I and the horizontal axis of the reference plane is 38°–42°, and the horizontal axis of the reference plane is set parallel to the strip-shaped protrusion VII.

[0009] The length ratio of strip-shaped protrusion I to strip-shaped protrusion II is 1-4 / 3; the length ratio of strip-shaped protrusion II to strip-shaped protrusion III is 1 / 4-1 / 2; the length ratio of strip-shaped protrusion III to strip-shaped protrusion IV is 3 / 2-9 / 5; the length ratio of strip-shaped protrusion IV to strip-shaped protrusion V is 5 / 4-3 / 2; the length ratio of strip-shaped protrusion V to strip-shaped protrusion VI is 1 / 2-3 / 5; and the length ratio of strip-shaped protrusion VI to strip-shaped protrusion VII is 2 / 5-4 / 5.

[0010] The ratio of the distance h from the inner intersection point A of strip-shaped protrusions III and IV to strip-shaped protrusion VII to the length of strip-shaped protrusion VII is in the range of 1–1.2.

[0011] The total area of ​​the protrusions in the second pattern is 3 / 81 to 1 / 10 of the area of ​​the protrusions in the first pattern.

[0012] The zigzag-shaped strip protrusion II includes strip protrusions i, ii, iii, iv, and v connected in sequence. The complementary angle a2 between strip protrusions i and ii is 65°–°, the angle b2 between strip protrusions ii and iii is 110°–115°, the angle c2 between strip protrusions iii and iv is 115°–119°, and the angle d2 between strip protrusions iv and v is 61°–65°.

[0013] The zigzag-shaped strip protrusion Ⅲ includes strip protrusions ⅵ, ⅶ, ⅷ, ⅸ, and ⅹ connected in sequence; strip protrusion ⅵ is on the same straight line as strip protrusion ⅰ of the third pattern, and the end of strip protrusion ⅵ away from strip protrusion ⅶ is connected to the end of strip protrusion ⅰ and strip protrusion ⅱ that are connected; the included angle e2 between strip protrusion ⅵ and strip protrusion ⅶ is 112°–116°, strip protrusion ⅷ is parallel to strip protrusion ⅵ, the included angle f2 between strip protrusion ⅷ and strip protrusion ⅸ is 116°–121°, and the included angle g2 between strip protrusion ⅸ and strip protrusion ⅹ is 59°–64°.

[0015] The fourth pattern has a length ratio between strip-shaped protrusion ⅵ and strip-shaped protrusion ⅰ of the third pattern ranging from 1 / 2 to 7 / 10; a length ratio between strip-shaped protrusion ⅵ and strip-shaped protrusion ⅷ ranging from 5 / 4 to 3 / 2; a length ratio between strip-shaped protrusion ⅷ and strip-shaped protrusion ⅸ ranging from 10 / 21 to 2 / 3; a distance h2 between strip-shaped protrusion ⅷ and strip-shaped protrusion ⅵ and a length ratio between strip-shaped protrusion ⅵ ranging from 2 / 5 to 3 / 5; and the end of strip-shaped protrusion ⅹ is connected to the third pattern.

[0016] A tire tread pattern block, wherein the pattern block is a pattern block having the aforementioned pattern block decoration.

[0017] A tire having the aforementioned tread blocks.

[0018] The beneficial effects of this utility model are that, by controlling the height and circumferential width of the protrusions in the first, second, third, and fourth tread patterns, on the one hand, it increases the friction between the tread block surface and the ground, thereby enhancing the traction and braking force of the tire tread block itself in rainy, muddy, and heavy-load uphill and downhill environments; on the other hand, the protrusion design located in the center of the tread block can appropriately reduce the contact stress between the center of the tread block surface and the ground, thereby appropriately improving the wear resistance and cut resistance of the tread block.

[0019] For tires used on mining machinery, the first tread block decoration on the non-grooved tread blocks can reduce the center stress of the tread by 6%-8%, and the brightness of this decoration is at least 4 units higher than other areas on the tread block surface. The second tread block decoration on the non-grooved tread blocks of the same tire can reduce the center stress of the tread by 8%-10%, and the brightness of this decoration is at least 5 units higher than other areas on the tread block surface. Furthermore, the first and second tread block decorations are formed by intersecting strip-shaped protrusions in different directions. These protrusions reflect light in different directions, increasing the brightness of the decoration and creating a brightness difference between the decoration and the surrounding non-protruding parts of the tread block, making the protrusion more prominent and giving these tires a high-end appearance.

[0050] A tire having the aforementioned tread blocks.

[0051] like Figure 9 As shown, this is a tread block decoration on the tire of a mining engineering machinery with a relatively large tread block area and volume. Based on the area and volume of the tread block, a first tread block decoration composed of a first pattern and a second pattern is used. The first tread block decoration consists of a protrusion on the surface of the tread block, protruding 1.2mm above the surface of the tire tread block in the normal direction.

[0062] The ratio of the distance h from the inner intersection point A of strip protrusions III13 and IV14 to strip protrusion VII17 to the length of strip protrusion VII17 is within the range of 1.05.

[0063] The total area of ​​the protrusions in the second pattern 2 is 11 / 125 of the area of ​​the protrusions in the first pattern 1.
