Description

Technical Field

[0001] This utility model relates to the field of tire technology, and in particular to a tread pattern structure for an all-steel tubeless radial truck tire. Background Technology

[0002] Tire tread patterns can be categorized into different types based on their intended use, so tread pattern design is developed according to the actual operating environment of the tire. A new tread pattern needs to comprehensively consider the actual market usage environment. For example, tire tread pattern design needs to improve the customer experience of using tire products in terms of driving comfort, noise, traction, and braking, increasing customer comfort while ensuring safety.

[0003] The main driving routes for tubeless tires on the market are paved roads and above. The main quality problems of these tires are shoulder voids, crown voids, and poor wear resistance. Shoulder voids are mainly caused by stress concentration and high-temperature aging, and are common in heavy-load, frequent steering, or poor heat dissipation conditions. Crown voids are mostly caused by excessive local impact loads or stones embedding and damaging the belt layer. Poor wear resistance is caused by uneven ground pressure distribution or abnormal wear.

[0004] CN220053403U discloses a tread pattern structure for a light-duty radial truck tire, including a tire tread with a Z-shaped zigzag groove in the center. Longitudinal zigzag grooves in opposite directions are evenly distributed along the centerline of the tread circumferentially towards both sides. Lateral ribs are evenly distributed from the main grooves of the longitudinal zigzag grooves towards the crown, with different slopes at the bottom of the grooves. However, this tire tread pattern structure cannot effectively remove stones during driving, easily leading to stones getting stuck in the crown, affecting tire lifespan. It is not suitable for tubeless radial tires designed for all-steel heavy-duty trucks.

[0005] Therefore, a new tread pattern structure suitable for all-steel tubeless radial truck tires still needs to be developed. Utility Model Content

[0006] The purpose of this invention is to overcome at least one defect of existing tire tread patterns, such as the crown being prone to trapping stones and wear, and to provide a tread pattern structure for an all-steel tubeless radial truck tire.

[0007] The objective of this utility model can be achieved through the following technical solutions:

[0008] A tread pattern structure for an all-steel tubeless radial truck tire includes a tire tread with three rows of Z-shaped grooves evenly distributed along its circumference. Two rows of block-shaped patterns are evenly distributed between adjacent grooves, forming a tread structure. The block-shaped patterns are all irregular hexagonal structures, with the two rows of block-shaped patterns staggered and facing opposite directions. Several rows of stones are arranged at the bottom of the grooves along their extension direction. At least some adjacent rows of stones are connected by stone protrusions, and the interior of the stone protrusions communicates with the interior of adjacent stone blocks, forming an exhaust channel. Exhaust holes are provided on some of the block-shaped patterns and some of the stone blocks.

[0009] Furthermore, the tire tread is composed of nine equal movable sections.

[0010] Furthermore, the tread pitch of the tire is 62 pitches.

[0011] Furthermore, the width of the zigzag groove is 15-17mm.

[0012] Furthermore, the depth of the zigzag groove is 16-18 mm.

[0013] Furthermore, the block pattern includes a first block pattern and a second block pattern.

[0014] Furthermore, within the same column of block patterns, the first block pattern and the second block pattern are alternately arranged.

[0015] Furthermore, the first block pattern is provided with a number of vent holes, which are distributed at the four corners of the hexagonal block pattern.

[0016] Furthermore, the surface of the second block pattern is provided with decorative fine lines, the depth of which is 0.8-1mm.

[0017] Furthermore, the length of the stone block is 5-7mm, preferably 6mm.

[0018] Furthermore, the width of the stone block is 2.5-3.5mm, preferably 3mm.

[0019] Furthermore, the height of the stone block is 1.8-2.2mm, preferably 2mm.

[0020] Furthermore, the vent holes on the stone-discharging blocks are arranged at intervals of every two stone-discharging blocks.

[0021] Furthermore, the protrusions for disposing of stones are at the same height as the stones.

[0022] Furthermore, the width of the stone-discharging protrusion is 0.5-0.7 mm, preferably 0.6 mm.

[0023] Furthermore, the length of the stone-discharging protrusion is 5-7mm, preferably 6mm.

[0024] Furthermore, the stone-discharging protrusions are arranged in a straight line corresponding to the straight segment of the zigzag groove.

[0025] Furthermore, the stone-dispensing protrusions are designed with an arc-shaped transition at the turning points of the zigzag groove.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] (1) The tire tread pattern structure of this utility model improves the exhaust and drainage performance during tire operation by setting the zigzag tread grooves; the staggered tread pattern structure helps to improve grip and reduce wear; the combined use of stone-removing blocks and stone-removing protrusions can effectively prevent stones from getting stuck in the zigzag tread grooves, and also helps to reduce the number of exhaust holes and improve exhaust performance; the combination of the above structures makes the tire tread pattern structure of this utility model have excellent anti-stone-clamping, drainage, exhaust and wear resistance performance, and has better applicability to ordinary roads and highway roads.

[0028] (2) The irregular hexagonal block pattern of this utility model has high wear resistance, which helps to reduce the probability of premature tire damage caused by uneven wear, uneven wear and stones stuck in the tire, and extends tire life. In addition, the block pattern helps to increase the contact area between the tread blocks and the ground, and helps to disperse stress. It can also provide biting force in different directions when the tire rolls, enhancing traction and braking performance in different directions.

[0029] (3) The stone-removing blocks and stone-removing protrusions of this utility model provide excellent drainage performance and anti-stone-clamping performance, which can be used to prevent stones from getting stuck in the tread grooves, so as to avoid stones on the crown damaging the tire or affecting the drainage performance.

[0043] Example 1:

[0044] This embodiment provides a tread pattern structure for an all-steel tubeless radial truck tire, including a tire tread 1. For example... Figure 1 As shown, the tire tread 1 has three rows of Z-shaped zigzag grooves 2 evenly distributed along its circumference, and two rows of block patterns 3 are evenly distributed between adjacent zigzag grooves 2, forming a pattern structure.

[0045] like Figure 2As shown, the block patterns 3 in this embodiment are all irregular hexagonal structures, with two rows of block patterns 3 arranged alternately and facing opposite directions. In this embodiment, the bottom of the zigzag groove 2 along its extension direction is provided with several rows of stones 4, and at least some adjacent rows of stones 4 are connected by stone protrusions 5. The interior of the stone protrusions 5 communicates with the interior of adjacent stone blocks 4, forming an exhaust channel. In this embodiment, some of the block patterns 3 and some of the stone blocks 4 are provided with exhaust holes 6.

[0046] The tire tread pattern structure in this embodiment improves the exhaust and drainage performance during tire operation by setting up three rows of zigzag grooves 2; the staggered hexagonal block pattern 3 helps to increase the contact area between the tread blocks and the ground, improving grip; the combined use of stone-removing blocks 4 and stone-removing protrusions 5 effectively prevents stones from getting stuck in the zigzag grooves 2, avoiding the impact of stones stuck in the crown on tire performance. At the same time, the exhaust channel formed by the stone-removing blocks 4 and stone-removing protrusions 5 also helps to reduce the number of exhaust holes, improving exhaust performance.

The tire tread 1 has three rows of Z-shaped zigzag grooves 2 evenly distributed along its circumference, and two rows of block-shaped patterns 3 are evenly distributed between adjacent zigzag grooves 2, forming a tread structure.

[0049] The difference from Example 1 is that the tire tread 1 in this example is composed of nine equal parts of movable mold, and the tread pitch of the tire tread 1 is 62 segments.

[0050] like Figure 3 As shown, the zigzag groove 2 in this embodiment adopts an open groove design with a width of 16mm and a depth of 17mm.

The tire tread 1 has three rows of Z-shaped zigzag grooves 2 evenly distributed along its circumference, and two rows of block-shaped patterns 3 are evenly distributed between adjacent zigzag grooves 2, forming a tread structure.

[0054] The difference from Embodiment 1 is that in this embodiment, the bottom of the zigzag groove 2 is provided with several rows of stones 4 along its extension direction, and at least some adjacent rows of stones 4 are connected by stone protrusions 5. The interior of the stone protrusions 5 is connected to the interior of the adjacent rows of stones 4, forming an exhaust channel. The exhaust holes 6 on the rows of stones 4 are provided at intervals of every two rows of stones 4, which can greatly reduce the number of exhaust holes 6 on the rows of stones 4.
