Detailed Implementation
[0025] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0026] like Figure 1-4 As shown, a hexagonal tread pattern for a high-mileage tire with all wheel positions, designed for medium- and short-distance heavy-duty driving, includes a crown pattern and a shoulder pattern 5. The crown pattern includes a first tread rib 3 and a second tread rib 4. The first tread rib 3 includes tread blocks 301 connected in series. The first tread rib 3 is mirror-symmetrical about a central axis, and then the second tread rib 4 is formed by translating half of the circumferential length of the tread blocks 301 along the tread circumference. A central tread groove 1 is provided between the first tread rib 3 and the second tread rib 4. A crown tread groove 2 is provided between the shoulder pattern 5 and the first tread rib 3 or the second tread rib 4. The design of the tread grooves gives the tire strong driving performance and a certain degree of traction.
[0027] The shoulder tread pattern 5 is located on both sides of the tread, forming a circumferential integral structure. The inner edge corresponds to the first tread rib 3 or the second tread rib 4, and the outer edge is provided with grooves 9 at intervals along the circumference, the interval being the circumferential length of the tread block. The grooves 9 on both sides are offset by 1 / 2 of the circumferential length of the tread block unit. The groove offset makes the stress distribution in the shoulder area more uniform, avoiding the problem of accelerated edge wear caused by concentrated groove openings, and extending the tire service life. The matching of the interval distance and the height of the tread block can ensure that the shoulder area forms a reasonable support structure between the drainage grooves and the tread, balancing drainage capacity and mechanical strength.
[0028] The first patterned rib 3 and the second patterned rib 4 are composed of patterned blocks 301 with equal pitches, and the number of pitches is 48. The equal pitches form regular drainage channels, which can more efficiently drain water when driving in wetlands and improve the safety of driving in wetlands.
[0029] The shoulder pattern 5 includes a series of shoulder pattern sections 501, which are composed of a pentagon HIGKL. The pentagon HIGKL includes a rectangle KIGL and an isosceles triangle GLK, which are formed by sharing a side LG.
[0030] The width ratio of the shoulder tread pattern 5 to the width of the first tread rib 3 or the second tread rib 4 is 1.1:1.
[0031] The angle between the groove 9 and the tire axle is 17°; for example Figure 8 As shown, the width kk of groove 9 is 26 mm; the depth L1 of groove 9 is 30 mm; the angle deg between the inclined surface of groove 9 and the vertical direction is 17°; as shown... Figure 6 As shown, the width and depth of the central tread groove 1 and the crown tread groove 2 are the same, with a width W1 of 14.6 mm and a depth L1 of 16 mm.
[0032] like Figure 5 As shown, the two side walls 10 of the central tread groove 1 and the crown tread groove 2 are provided with continuous and uninterrupted patterns, resembling dragon scales; the biomimetic scale topology structure realizes stress field redistribution, reduces the difference in wear rate between the crown and shoulder areas, extends the tire life cycle, and avoids vibration caused by irregular wear.
[0033] The tread pattern is formed by mirroring the pattern on the left side of the central axis and then shifting the pattern block 301 circumferentially by half its length to form the pattern on the right side.
[0034] Patterned block 301 is composed of hexagons ABCDE, which are divided by shallow steel grooves 7 and deep steel grooves 6. The deep steel groove 6 includes a first straight segment MO, a second straight segment OP, and a third straight segment PN. The deep steel groove is Z-shaped, and the first straight segment MO and the third straight segment PN are parallel to each other. One end of the deep steel groove 6 is connected to line segment AB, and the other end is connected to line segment EF. The shallow steel groove 7 includes shallow steel groove I 701 and shallow steel groove II 702, which are located on opposite sides of the deep steel groove 6. Shallow steel groove I 701 and shallow steel groove II 702 are parallel to each other. One end of shallow steel groove I 701 is connected to the bend point O of the deep steel groove 8. The other end of 701 is connected to line segment CD; one end of shallow steel plate groove II 702 is connected to the other bend point P of deep steel plate groove, and the other end of shallow steel plate groove II 702 is connected to line segment FG; line segments AB and FD are parallel to each other; a stepped depth design is adopted to reduce local stress concentration caused by tread deformation, achieve gradual deformation when the tread touches the ground, improve the uniformity of ground contact, and thus improve tire wear resistance; the connection design between the center tread groove and the crown tread groove improves drainage and heat dissipation efficiency; the design of the connection midpoint of the shallow steel plate groove optimizes steering response and ground contact uniformity.
[0035] like Figure 7 As shown, both the deep steel plate groove 6 and the shallow steel plate groove 7 are 2D straight-line designs. The depth L1 ratio of the deep steel plate groove 6 to the shallow steel plate groove 7 is 2.5:1, and the bottom C1 is arc-shaped. The width W1 of both the deep steel plate groove 6 and the shallow steel plate groove 7 is 0.7 mm. The bottom C1 is arc-shaped. The angle between the first straight segment MO or the third straight segment PN of the deep steel plate groove and the tire axis is 66°. The angle between the second straight segment OP of the deep steel plate groove and the tire axis is 47°. The angle between the shallow steel plate groove 7 and the tire axis is 25°.
[0036] The shape formed by the shallow steel plate groove I 701, the first straight segment MO of the deep steel plate groove, and the outer edge of the patterned block is trapezoid a. The shape formed by the shallow steel plate groove II 702, the third straight segment PN of the deep steel plate groove, and the outer edge of the patterned block is trapezoid b. Trapezoid a and trapezoid b are completely identical and both are provided with knurling 8. The knurling improves grip and inhibits overall wear.
[0037] like Figure 9 As shown, this utility model provides a high-mileage tire tread block, tread rib, and tread pattern for all wheel positions, specifically designed for medium- and short-distance heavy-duty driving. The tire tread block of this utility model adopts a stepped design with fine and deep steel plate grooves, which can make the tire's driving force stronger and the wear more uniform. The design of the tread groove parameters and positions, combined with the design of the tread pitch, increases the area of the tread block. Compared with the existing tire tread structure, the tread saturation is increased by 10%, and the product's mileage is increased by 10% year-on-year. The design of the shoulder groove and the design angle of the tread groove enable the tread to have anti-bottom cracking and anti-stone-entrapment performance.
