Description

Technical Field

[0001] This utility model belongs to the field of radial tires, and particularly relates to an all-steel tubeless radial truck tire. Background Technology

[0002] The core concept of tire tread pattern design lies in improving driving performance and enhancing aesthetics by setting different shaped grooves and patterns on the tire surface. Tire tread groove designs are divided into three types: longitudinal, lateral, and diagonal. These different tread layouts significantly affect tire grip, water drainage performance, and handling. Generally speaking, longitudinal tread patterns are known for their excellent guidance and water drainage capabilities, while also producing less noise and rolling resistance at high speeds. Lateral tread patterns are superior to longitudinal tread patterns in terms of driving and braking performance, but they have poorer lateral stability, are prone to greater slippage, and produce more noise and rolling resistance. As for block tread patterns, they offer the best dynamic performance. The block arrangement of the tread pattern allows the pattern to penetrate deep into the ground when the vehicle is driving on snow or muddy roads, thereby generating effective driving force.

[0003] The choice of tire tread pattern depends on different needs. The design process is extremely complex and challenging. Multiple factors must be balanced during the design phase: for example, emphasizing grip may result in greater noise, while optimizing water drainage may affect the tire's high-speed rotation. In other words, focusing on a specific performance characteristic may negatively impact other performance aspects. As society progresses and market demands evolve, tire usage conditions become more demanding. Utility Model Content

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described and explained below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments provided by this utility model without inventive effort are within the scope of protection of this utility model.

[0040] This utility model embodiment provides an all-steel tubeless radial truck tire. Figure 1 This is a structural schematic diagram of an all-steel tubeless radial truck tire according to an embodiment of the present invention.

[0041] refer to Figure 1 As shown, this all-steel tubeless radial truck tire includes: a left tread rib and a right tread rib; the left tread rib is formed by alternating arrangements of a first left tread block 101 and a second left tread block 102 along the circumferential direction of the tire tread, as shown. Figure 2 As shown, the first left tread block 101 has several fine grooves arranged parallel to the first direction on the left side, and the second left tread block 102 has several fine grooves arranged parallel to the second direction on the left side. The first direction and the second direction are different. The right tread rib is formed by the alternating arrangement of the first right tread block 103 and the second right tread block 104 along the circumference of the tire tread. The first right tread block 103 has several fine grooves arranged parallel to the first direction on the right side, and the second right tread block 104 has several fine grooves arranged parallel to the second direction on the right side. On the same horizontal direction of the tire tread, the left side is the first left tread block 101, and the right side is the second right tread block; and the left side is the second left tread block 102, and the right side is the first right tread block 103.

[0042] The aforementioned all-steel tubeless radial truck tire improves drainage and snow removal capabilities, as well as stone removal capabilities, by setting fine grooves in different directions on the first left tread block 101 and the second left tread block 102, and limiting them to the same horizontal direction. The fine grooves on the left and right tread ribs have different directions. At the same time, due to the different orientations of the inclined sections on both sides and the surrounding grooves (main longitudinal grooves, fine longitudinal grooves and transverse grooves), the friction between the tread and the ground is increased, which enhances the tire's traction and lateral force.

[0043] In some embodiments, a first transverse groove 201 is provided between adjacent first left-side patterned blocks 101 and second left-side patterned blocks 102, and the first transverse groove 201 has a first bending portion 2011 that bends upward or downward; a second transverse groove 202 is provided between adjacent first right-side patterned blocks 103 and second right-side patterned blocks 104, and the second transverse groove 202 has a second bending portion 2021, the bending direction of the second bending portion 2021 being opposite to the bending direction of the first bending portion 2011.

[0044] In some embodiments, a plurality of fine lines form a first diagonal block 301 on a first left-side patterned block 101, a plurality of fine lines form a second diagonal block 302 on a second left-side patterned block 102, a plurality of fine lines form a third diagonal block 303 on a first right-side patterned block 103, and a plurality of fine lines form a fourth diagonal block 304 on a second right-side patterned block 104; a first horizontal groove 201 defines the upper and lower boundaries of the first diagonal block 301 and the second diagonal block 302, and a second horizontal groove 202 defines the upper and lower boundaries of the third diagonal block 303 and the fourth diagonal block 304.

[0045] In the aforementioned tire, the first lateral groove 201 and the second lateral groove 202 divide the left and right tread ribs into various tread blocks, respectively. The first lateral groove 201 and the second lateral groove 202 are connected to some of the diagonal tread blocks with different tread patterns, which improves the tire's water drainage, snow removal and stone removal capabilities, while also increasing the friction between the tire tread and the ground, and strengthening the tire's traction and lateral force.

[0046] like Figure 7 As shown, the left tread rib is provided with a first fine longitudinal groove 401 extending circumferentially along the tire tread, and the right tread rib is provided with a second fine longitudinal groove 402 extending circumferentially along the tire tread; the first fine longitudinal groove 401 and the second fine longitudinal groove 402 are arranged parallel to each other; the first fine longitudinal groove 401 defines the right boundary of the first tread block 301 and the second tread block 302, and the first fine longitudinal groove 401 intersects with the first transverse groove 201 at the first bend 2011; the second fine longitudinal groove 402 defines the left boundary of the third tread block 303 and the fourth tread block 304, and the second fine longitudinal groove 402 intersects with the second transverse groove 202 at the second bend 2021.

[0047] The first longitudinal groove 401 and the first transverse groove 201 intersect on the left tread rib. At the same time, the first longitudinal groove 401 and the first transverse groove 201 define the boundaries of the first diagonal tread block 301 and the second diagonal tread block 302, which is conducive to water drainage and snow removal. Similarly, the second longitudinal groove 402 and the second transverse groove 202 intersect on the right tread rib. At the same time, the second longitudinal groove 402 and the second transverse groove 202 define the boundaries of the third diagonal tread block 303 and the fourth diagonal tread block 304, which is also conducive to water drainage and snow removal. This improves the tire's water drainage and snow removal performance and ensures the tire's driving safety under various road conditions.

[0048] In some embodiments, the tire also includes main longitudinal grooves extending circumferentially along the tire tread. These main longitudinal grooves include a first main longitudinal groove 501, a second main longitudinal groove 502, a third main longitudinal groove 503, and a fourth main longitudinal groove 504 arranged parallel from left to right. A left-side tread rib is located between the first and second main longitudinal grooves 501, and the first main longitudinal groove 501 defines the left boundary of the first tread block 301 and the second tread block 302. A right-side tread rib is located between the third and fourth main longitudinal grooves 503, and the fourth main longitudinal groove 504 defines the right boundary of the third and fourth tread blocks 303 and 304. Wherein, as... Figure 3 As shown, there is a protrusion in the middle of the bottom of the main longitudinal groove. The design of the protrusion improves the tire's stone removal and water drainage performance.

[0049] The four twill block areas of this utility model are separated by upper and lower horizontal streamlined shallow grooves (first horizontal groove 201, second horizontal groove 202), and are also separated by main longitudinal grooves and longitudinal streamlined shallow grooves (first fine longitudinal groove 401, second fine longitudinal groove 402). The pattern block areas have a large span, and different pattern blocks have different tendencies, which is beneficial for longitudinal control and lateral anti-skid, and improves the straight-line driving stability of the vehicle.

[0050] In some embodiments, the two ends of the first transverse groove 201 are respectively connected to the first main longitudinal groove 501 and the second main longitudinal groove 502; the two ends of the second transverse groove 202 are respectively connected to the third main longitudinal groove 503 and the fourth main longitudinal groove 504.

[0051] In some embodiments, the main longitudinal groove is bent, including a straight portion 5011 and a third bent portion 5012 connecting adjacent straight portions 5011. The two ends of the first transverse groove 201 are connected to the first main longitudinal groove 501 and the second main longitudinal groove 502 through the third bent portion 5012. The two ends of the second transverse groove 202 are connected to the third main longitudinal groove 503 and the fourth main longitudinal groove 504 through the third bent portion 5012.

[0052] like Figure 4 , 5 As shown in Figures 6 and 7, the width of the connection between the first horizontal groove 201 and the third bend 5012 is the largest, and the width of the connection between the second horizontal groove 202 and the third bend 5012 is the largest.

[0053] In this invention, the two ends of the first transverse groove 201 are connected to the first main longitudinal groove 501, and the two ends of the second transverse groove 202 are connected to the second main longitudinal groove 502 by oblique lines, which makes the transition smoother and gentler, providing better handling performance for the tire, and also improving the heat dissipation performance of the tire during driving.

[0054] like Figure 8 , 9As shown, an intermediate tread rib 6 is defined between the second main longitudinal groove 502 and the third main longitudinal groove 503; the intermediate tread rib 6 is provided with a third fine longitudinal groove 7 extending circumferentially along the tire tread, one end of which is connected to the third fine longitudinal groove 7, and the other end is connected to the third transverse groove 801 of the second main longitudinal groove 502 through a straight portion 5011, and a fourth transverse groove 802 connected to the third fine longitudinal groove 7 at one end and connected to the third main longitudinal groove 503 at the other end through a straight portion 5011; the third transverse groove 801 and the fourth transverse groove 802 are arranged alternately along the tire tread circumferentially.

[0055] The aforementioned tires feature a mixed tread pattern of straight and zigzag grooves, exhibiting excellent resistance to uneven wear. The deep main longitudinal grooves ensure a long wear life and superior tire durability. The overall asymmetrical tread pattern creates rigid cross-sections, enhancing straight-line stability on various road surfaces. Excellent water and snow drainage performance further improves stability on challenging terrains such as snow-covered or waterlogged surfaces, while also maintaining functionality on normal roads.

[0056] In some embodiments, the left side of the first main longitudinal groove 501 defines a left shoulder tread rib 901, and the right side of the fourth main longitudinal groove 504 defines a right shoulder tread rib 902. The left shoulder tread rib 901 has a fifth transverse groove 1001 with one end connected to the first main longitudinal groove 501, and the right shoulder tread rib 902 has a sixth transverse groove 1002 with one end connected to the fourth main longitudinal groove 504. The depth of the fifth transverse groove 1001 and the sixth transverse groove 1002 is 2-3 mm. In this invention, the addition of tread grooves to the shoulder, with a groove depth of 2-3 mm, can improve the vulcanization efficiency of the shoulder area, increase the heat dissipation performance of the shoulder area, and reduce the risk of tire shoulder gaps. Figure 10 As shown, the flower 11 on the shoulder is shaped like a water droplet, which not only improves heat dissipation in the shoulder area but also serves as a warning to prevent symptoms caused by excessive heat in the shoulder.

[0057] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
