Abstract
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 hollowing, crown hollowing, and poor wear resistance. Shoulder hollowing (delamination or cracking in the tire shoulder area) is mainly caused by stress concentration and high-temperature aging, and is common in heavy-load, frequent steering, or poor heat dissipation conditions. Crown hollowing (delamination in the tire crown area) is mostly caused by excessive local impact load or stones embedding and damaging the belt layer. Poor wear resistance stems from uneven ground pressure distribution or abnormal wear (such as stone scratches or local overheating softening).
[0004] CN222179117U discloses a tread pattern structure for a light-duty radial tire, but it only has one central longitudinal tread block and two rows of longitudinal tread blocks, which cannot effectively solve the problems of uneven ground pressure distribution and shoulder gaps. It is not suitable for tubeless radial tires with all-steel load capacity.
[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 of the defects of existing tire tread patterns, such as uneven ground pressure distribution, easy gaps, and inability to effectively remove stones, 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] This utility model provides a tread pattern structure for an all-steel tubeless radial truck tire, including a tire tread and several block patterns distributed circumferentially on the tire tread.
[0009] The block pattern includes three rows of central block patterns located in the middle of the tire tread and two rows of edge block patterns located on the shoulder of the tire tread; wherein, straight grooves are formed between adjacent rows of central block patterns and between adjacent rows of central block patterns and edge block patterns.
[0010] In each column of central block patterns, a central pattern transverse groove is formed between adjacent central block patterns; in each column of edge block patterns, an edge pattern transverse groove is formed between adjacent edge block patterns; the pattern grooves are connected to the adjacent central pattern transverse grooves and / or edge pattern transverse grooves, and both the central pattern transverse grooves and the edge pattern transverse grooves are provided with arranged stones;
[0011] The tire tread has shoulder grooves evenly distributed on its shoulder.
[0012] Furthermore, the tire tread is composed of nine equal movable sections.
[0013] Furthermore, the tread pitch of the tire is 52 pitches.
[0014] Furthermore, both the central block pattern and the edge block pattern are parallelogram structures, and the four corners of the parallelogram structure are all rounded chamfers.
[0015] Furthermore, the single-side dimension of the edge block pattern is larger than that of the central block pattern.
[0016] Furthermore, the central block patterns in the middle column face opposite directions to the central block patterns in the two side columns, and are arranged in an alternating pattern.
[0017] Furthermore, decorative grooves are provided on both the central block pattern and the edge block pattern.
[0018] Furthermore, the middle part of the decorative groove is a wavy groove, and the two sides of the pattern are straight grooves.
[0019] Furthermore, several vent holes are distributed around the central block pattern and the edge block pattern.
[0020] Furthermore, the diameter of the vent hole is 0.6-1 mm, preferably 0.8 mm.
[0021] Furthermore, the bottom of the patterned straight groove is provided with an open groove.
[0022] Furthermore, the width of the patterned straight groove is 5-7mm, preferably 6mm; the depth of the patterned straight groove is 19-20mm, preferably 19.5mm.
[0023] Furthermore, the width of the central patterned groove is 3-4 mm, preferably 3.5 mm; the width of the edge patterned groove is 5-7 mm, preferably 6 mm.

[0025] Compared with the prior art, the present invention has the following beneficial effects:
[0026] (1) The tread pattern structure of this utility model optimizes the ground pressure distribution through the modular block design of the central block pattern and the edge block pattern, and has a good wear resistance effect. The tread pattern straight groove, the central tread pattern transverse groove and the edge tread pattern transverse groove form a mesh-like drainage, air venting and heat dissipation path.

[0045] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0046] Example 1:
[0047] This embodiment provides a tread pattern structure for an all-steel tubeless radial truck tire, such as... Figure 1 As shown, it includes a tire tread 1 and several block-shaped patterns 2 distributed circumferentially on the tire tread 1.
[0048] The block pattern 2 in this embodiment includes three rows of central block patterns 21 located in the middle of the tire tread 1 and two rows of edge block patterns 22 located on the shoulders of the tire tread 1. Vertical grooves 3 are formed between adjacent rows of central block patterns 21 and between adjacent rows of central block patterns 21 and edge block patterns 22. In each row of central block patterns 21, horizontal grooves 4 are formed between adjacent central block patterns 21. In each row of edge block patterns 22, horizontal grooves 5 are formed between adjacent horizontal grooves 22. The vertical grooves 3 communicate with adjacent horizontal grooves 4 and / or horizontal grooves 5, and both the horizontal grooves 4 and 5 contain padded stones 6.
[0049] In this embodiment, the shoulder of the tire tread 1 is evenly distributed with shoulder heat dissipation grooves 7, which can effectively improve the heat dissipation effect of the shoulder of the tire tread 1 and avoid the occurrence of shoulder cracks.
[0050] In this embodiment, three rows of central block patterns 21 are arranged in the central area of the tire tread 1 to bear the main driving / braking load. The dense arrangement of the central block patterns 21 can effectively enhance the rigidity of the central area and reduce tread deformation during braking / acceleration. Two rows of edge block patterns 22 are arranged at the shoulder positions on both sides of the tire tread 1 to enhance lateral support and prevent premature wear of the tire shoulders. In addition, this embodiment also constructs a mesh-like drainage, ventilation, and heat dissipation path through the straight grooves 3, the transverse grooves 4, and the transverse grooves 5 formed between the central block patterns 21 and the edge block patterns 22. Stone deflectors 6 are placed in the transverse grooves 4 and the transverse grooves 5 to prevent stones from getting stuck in the crown of the tire during driving.
[0051] Example 2:
[0052] This embodiment provides a tread pattern structure for an all-steel tubeless radial truck tire, including a tire tread 1 and several block patterns 2 distributed circumferentially on the tire tread 1.
[0053] In this embodiment, the tire tread 1 is composed of nine equal parts of movable mold, and the tread pitch of the tire tread 1 is 52 segments.
[0054] In this embodiment, the block pattern 2 includes three rows of central block patterns 21 located in the middle of the tire tread 1 and two rows of edge block patterns 22 located on the shoulders of the tire tread 1. Both the central block patterns 21 and the edge block patterns 22 are parallelogram structures with rounded corners to eliminate stress concentration at right angles and reduce the risk of cracking at the root of the block pattern 2. The single-side dimension of the edge block patterns 22 is larger than that of the central block patterns 21 to enhance the rigidity of the tire shoulder area and resist shoulder deformation caused by lateral force compression. The central block patterns 21 in the middle row face opposite directions to the central block patterns 21 in the two side rows, forming an alternating distribution. This misaligns the contact points of the block patterns 2 in different rows, dispersing the ground impact force and reducing localized wear.
[0055] like Figure 2 As shown, decorative grooves 8 are provided on both the central block pattern 21 and the edge block pattern 22 in this embodiment to accelerate heat dissipation. The central part of the decorative groove 8 is a wavy groove, and the grooves between the wavy groove and the two sides of the pattern are straight grooves. Several vent holes 9 with a diameter of about 0.8 mm are distributed around the perimeter and four corners of the central block pattern 21 and the edge block pattern 22 to cover stress concentration areas (such as chamfered corners) and areas with high heat dissipation requirements.
[0056] In this embodiment, pattern grooves 3 are formed between the middle block patterns 21 of adjacent columns and between the middle block patterns 21 and the edge block patterns 22 of adjacent columns. The bottom of the pattern grooves 3 has an open groove 31. In this embodiment, the width of the pattern grooves 3 is 6 mm, and the depth of the pattern grooves 3 is 19.5 mm. In each column of the middle block patterns 21, a middle pattern transverse groove 4 is formed between adjacent middle block patterns 21. In each column of the edge block patterns 22, an edge pattern transverse groove 5 is formed between adjacent edge block patterns 22. In this embodiment, the width of the middle pattern transverse groove 4 is 3.5 mm, and the width of the edge pattern transverse groove 5 is 6 mm. In this embodiment, the pattern grooves 3 are connected to the adjacent middle pattern transverse grooves 4 and / or edge pattern transverse grooves 5. The straight grooves 3, the horizontal grooves 4 in the middle, and the horizontal grooves 5 on the edge together form a longitudinally and laterally connected, extended drainage or airflow channel.
[0057] In this embodiment, the densely arranged central block pattern 21 enhances the rigidity of the central area, reduces tread deformation during braking / acceleration, and is suitable for high-load scenarios. The edge block pattern 22 is flexibly connected through lateral grooves, improving the uniformity of contact with the ground during cornering and avoiding abnormal wear caused by stress concentration on the tire shoulder. In addition, the independent interlocking edges of the block pattern 2 provide additional traction on low-traction surfaces such as mud and snow. Furthermore, the lateral grooves (central tread groove 4 and edge tread groove 5) in this embodiment are connected to the tread grooves 3, breaking the "hydroplaning zone" of the continuous pattern and improving the stability of wet grip.
[0058] In this embodiment, both the central groove 4 and the edge groove 5 are equipped with stone-discharging blocks 6. The length of the stone-discharging block 6 is 24mm, the width of the stone-discharging block 6 is 3.5mm, and the height of the stone-discharging block 6 is 5.5mm. When the tire rolls, the mechanical stress generated by the deformation of the central groove 4 and the edge groove 5, together with the centrifugal force, pushes the stones outward, achieving the stone-discharging effect.
[0059] In this embodiment, the shoulder of the tire tread 1 is evenly distributed with shoulder heat dissipation grooves 7, which guide high-speed airflow through the interior of the tread. The depth of the shoulder heat dissipation grooves 7 is 5mm, and there are rounded transitions at the external corners and the internal corners at the bottom of the grooves, which can effectively improve the heat dissipation effect of the shoulder of the tire tread 1 and prevent shoulder cracks from occurring.
[0060] The above description of the embodiments is provided to enable those skilled in the art to understand and use the utility model. It will be apparent to those skilled in the art that various modifications can be easily made to these embodiments, and the general principles described herein can be applied to other embodiments without inventive effort. Therefore, the present utility model is not limited to the above embodiments, and any improvements and modifications made by those skilled in the art based on the disclosure of the present utility model without departing from its scope should be within the protection scope of the present utility model.
