A pattern for an all-steel radial truck tire and the tire itself.

Abstract

This invention proposes an all-steel radial truck tire tread pattern and tire, belonging to the field of tire technology. It includes multiple longitudinal main grooves extending circumferentially along the tread and multiple tread blocks separated by adjacent longitudinal main grooves. The number of longitudinal main grooves is odd, and greater than or equal to three. The top surface height of each tread block gradually decreases from the longitudinal main groove on one side to the longitudinal main groove on the other side, and the decreasing trend of the top surface height of each tread block is the same. By limiting the top surface height of the tread blocks to gradually decrease from the longitudinal main groove on one side to the longitudinal main groove on the other side, this invention significantly improves water drainage and snow removal performance, and also helps to enhance grip, longitudinal handling, and lateral anti-skid performance, thereby improving the straight-line stability of the vehicle. Furthermore, because the decreasing trend of multiple tread blocks is the same, the design is asymmetrical relative to the centerline of the tread, resulting in rigid cross-sections of the tread, further improving the straight-line stability of the vehicle on various road surfaces.

Description

Technical Field

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

[0002] The core of tire tread pattern design lies in improving driving performance and enhancing aesthetics by setting different shaped grooves and patterns on the tire surface. Common tire tread grooves 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] Tire tread design must comprehensively consider vehicle purpose, road conditions, and operating environment. For example, high-speed vehicles need to prioritize low noise and low rolling resistance, while off-road or winter vehicles need to enhance grip and mud / snow removal capabilities. A well-designed tread pattern should not only effectively improve anti-skid performance and traction but also reduce driving noise to a certain extent, thereby comprehensively improving the safety and comfort of the entire vehicle. While existing technologies have optimized specific performance aspects for different types of tire treads, it is often difficult to simultaneously achieve optimal performance across multiple areas such as anti-skid, grip, and water drainage. Utility Model Content

[0004] To address the shortcomings of related technologies, this invention provides an all-steel radial truck tire tread pattern and tire, which solves the technical problem that traditional tire tread patterns cannot simultaneously achieve multiple performances such as anti-skid, grip, and water drainage. It features strong grip, strong water drainage, good anti-skid performance, and the ability to improve vehicle driving stability.

[0005] This utility model proposes a tread pattern for an all-steel radial truck tire, including: Multiple longitudinal main grooves extending circumferentially along the tread and multiple pattern blocks separated by adjacent longitudinal main grooves; The number of longitudinal main ditches is odd, and greater than or equal to 3; The height of the top surface of the patterned block gradually decreases from the longitudinal main groove on one side to the longitudinal main groove on the other side. In the same horizontal direction, the height of the top surface of each patterned block on the same side is consistent and the decreasing trend is the same.

[0006] In some embodiments, each tread block has oblique grooves that are distributed circumferentially on the tread and obliquely penetrate the tread block. The width of the oblique grooves at both ends is greater than the width at the middle, and the depth at both ends is greater than the depth at the middle.

[0007] In some embodiments, each tread block also has a longitudinal shallow groove extending circumferentially along the tread, the longitudinal shallow groove being located on the centerline of the tread block and communicating with an oblique groove.

[0008] In some embodiments, each tread block also has a group of tread blocks distributed circumferentially along the tread, the group of tread blocks connecting adjacent longitudinal main grooves; the group of tread blocks includes several parallel inclined segments; The diagonal pattern blocks on different patterned blocks are arranged in a staggered parallel manner in the horizontal direction, and the inclined sections within each diagonal pattern block group have the same inclination direction. The cross-section of the inclined section is trapezoidal, and the width of its base is greater than the width of its top surface.

[0009] In some embodiments, the oblique grooves within each patterned block divide the twill block group into a left twill block and a right twill block, with the left twill block and the right twill block located on either side of the longitudinal shallow groove, respectively.

[0010] In some embodiments, the longitudinal main groove is zigzag-shaped, and its bottom surface extends radially outward to the tread surface to form a groove with gradually increasing width.

[0011] In some embodiments, the bottom of the longitudinal main groove is provided with continuous wavy protrusions along the circumferential direction of the tread, and the bending trend of the wavy protrusions is the same as that of the longitudinal main groove.

[0012] In some embodiments, the bends of the longitudinal main channels are not on the same horizontal line.

[0013] In some embodiments, the above-mentioned all-steel radial truck tire tread pattern further includes shoulder tread blocks located on both sides of the tire shoulder; The shoulder tread blocks have shoulder transverse grooves arranged circumferentially along the tread. One end of the shoulder transverse groove extends to the underside of the shoulder, and the other end passes through the adjacent longitudinal main groove and extends into the adjacent tread block.

[0014] This utility model also provides a tire having the above-mentioned tire tread pattern.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention provides a tread pattern for an all-steel radial truck tire. By limiting the height of the top surface of the tread blocks to gradually decrease from the longitudinal main groove on one side to the longitudinal main groove on the other side, it significantly improves water drainage and snow removal performance, and also helps to enhance grip, longitudinal handling and lateral anti-skid performance, thereby improving the straight-line driving stability of the vehicle. Furthermore, since the decreasing trend of multiple tread blocks is the same, the design is asymmetrical relative to the center line of the tread, making the tread rigidly intersecting, which further improves the straight-line driving stability of the vehicle on various road surfaces.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] In the description of this invention, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0019] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0020] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0021] like Figure 1 , 2 As shown, the tread pattern of this all-steel radial truck tire includes multiple longitudinal main grooves 1 extending circumferentially along the tread and multiple tread blocks 2 separated by adjacent longitudinal main grooves 1; the number of longitudinal main grooves 1 is odd, and greater than or equal to 3. Figure 1 The diagram shows a structure with three longitudinal main grooves 1. The top surface height of the patterned block 2 gradually decreases from the longitudinal main groove 1 on one side to the longitudinal main groove 1 on the other side. In the same horizontal direction, the top surface height of each patterned block 2 on the same side is consistent, and the decreasing trend is the same.

[0022] The aforementioned all-steel radial truck tire tread pattern, by limiting the height of the top surface of the tread block 2 to gradually decrease from the longitudinal main groove 1 on one side to the longitudinal main groove 1 on the other side, significantly improves water drainage and snow removal performance, and helps to enhance grip, longitudinal handling and lateral anti-skid performance, thereby improving the straight-line driving stability of the vehicle. Moreover, since the decreasing trend of multiple tread blocks 2 is the same, the tread is asymmetrically designed relative to the center line of the tread, making the tread rigidly intersecting, further improving the straight-line driving stability of the vehicle on various road surfaces.

[0023] In some embodiments, the number of longitudinal main channels 1 is 3, 5, or 7.

[0024] In some embodiments, each tread block 2 has oblique grooves 3 that are distributed circumferentially on the tread and obliquely penetrate the tread block 2, and the oblique grooves 3 connect to adjacent main grooves.

[0025] The above structural design, by setting oblique grooves 3 to connect adjacent longitudinal main grooves 1, can prevent air from being blocked when the tread contacts the ground, reduce the number of closed tread grooves when the tread blocks 2 contact the ground, thereby reducing resonance and achieving the effect of reducing noise.

[0026] like Figure 1-4 As shown, in some embodiments, the width at both ends of the inclined groove 3 is greater than the width at the middle, and the depth at both ends is greater than the depth at the middle. Specifically, the depth at both ends of the inclined groove 3 is 7 mm, and the width is 1.4 mm; the depth at the middle is 3 mm, and the width is 1 mm; the bottom of the groove adopts a full circular arc transition.

[0027] The above structural design, by setting variations in the depth and width of the inclined groove 3 at both ends and the middle, can increase the tire's drainage performance and improve its wet grip performance.

[0028] like Figure 1 As shown, in some embodiments, each tread block 2 also has a longitudinal shallow groove 4 extending circumferentially along the tread, the longitudinal shallow groove 4 being located on the centerline of the tread block 2 and communicating with the oblique groove 3.

[0029] Furthermore, the longitudinal shallow trench 4 is a longitudinal straight trench with a depth of 3mm and a width of 1mm, and the corners and the bottom of the trench are transitioned by a full arc.

[0030] The above structural design improves drainage and reduces the closure of tread grooves, effectively preventing air blockage when the tire tread contacts the ground, thereby reducing resonance, significantly reducing driving noise, and improving ride comfort.

[0031] In some embodiments, each tread block 2 also has a tread block group 5 distributed along the circumferential direction of the tread, the tread block group 5 connecting adjacent longitudinal main grooves 1; the tread block group 5 includes several parallel inclined segments; the tread block groups 5 on different tread blocks 2 are arranged in a staggered parallel manner in the horizontal direction, and the inclined segments in each tread block group 5 have the same inclined direction.

[0032] The design of the oblique tread block group 5 in this utility model improves the drainage and snow removal capabilities in the first aspect, the stone removal capability in the second aspect, and the traction and lateral force of the tire are enhanced by increasing the friction between the tread and the ground in the third aspect. The oblique tread block group 5 on different pattern blocks 2 is set as an asymmetrical design, so that the tread rigidity is crossed, which improves the straight-line driving stability of the vehicle on various road surfaces, has excellent drainage and snow removal performance, enhances the stability of driving on harsh ground surfaces, such as snow and water, and also takes into account the driving function on normal road surfaces.

[0033] In some embodiments, the oblique grooves 3 in each patterned block 2 divide the twill block group 5 into a left twill block 51 and a right twill block 52, and the left twill block 51 and the right twill block 52 are located on both sides of the longitudinal shallow groove 4, respectively.

[0034] The above structural design sets the twill block group 5 to be separated by the slanted groove 3 and the longitudinal shallow groove 4. The pattern block 2 area has a large span, which is beneficial for longitudinal control and lateral anti-slip, and improves the straight-line driving stability of the vehicle.

[0035] like Figure 1 , 5 As shown, in some embodiments, the inclined segment has a trapezoidal cross-section, with its base width greater than its top width. The inclined segment can be a steel sheet.

[0036] The above structural design widens and deepens the bottom of the inclined section to connect with the main groove, making the transition smoother and gentler. This provides better handling performance for the tire, improves the tire's heat dissipation performance during driving, and reduces driving noise.

[0037] like Figure 1 , 6 As shown, in some embodiments, the longitudinal main groove 1 is zigzag-shaped, and its bottom surface extends radially outward to the tread surface to form a groove with gradually increasing width.

[0038] The above structural design sets the longitudinal main groove 1 as a broken line shape. Compared with straight line treads, broken line treads can provide better driving force and grip during tire use; reducing the tread groove width and increasing the tread saturation can improve the wear resistance; the deep tread design results in a long wear life; and the tire body has excellent durability.

[0039] In some embodiments, the bottom of the longitudinal main groove 1 is provided with continuous wavy protrusions 6 along the circumferential direction of the tread, and the wavy protrusions 6 transition with the bottom of the longitudinal main tread groove in an arc. The bending trend of the wavy protrusions 6 is the same as that of the longitudinal main groove 1.

[0040] The above structural design incorporates a wavy protrusion 6 at the bottom of the longitudinal main groove 1. This wavy protrusion 6 improves the tire's stone removal and water drainage performance, protects the tread groove bottom from punctures, and prevents groove bottom cracking. In some embodiments, the bends of the longitudinal main channels 1 are not on the same horizontal line.

[0041] The aforementioned structural design reduces the resonance coupling effect of the longitudinal main groove 1 during driving, optimizes noise control, and improves the multi-point contact characteristics between the tire tread and the ground, thereby enhancing grip and handling stability. Furthermore, this structural design helps to disperse the contact pressure between the tire tread and the ground, avoiding stress concentration in the same horizontal direction, reducing early or irregular tread wear, and thus significantly improving tire wear resistance and service life.

[0042] like Figure 1 , 7 As shown, in some embodiments, the tread pattern of the all-steel radial truck tire also includes shoulder tread blocks 7 located on both sides of the tire shoulder. The shoulder tread block 7 has shoulder transverse grooves 8 arranged circumferentially along the tread, one end of which extends to the underside of the shoulder, and the other end passes through the adjacent longitudinal main groove 1 and extends into the adjacent tread block 2. The depth of the shoulder transverse groove 8 is 2-3 mm.

[0043] The above structural design, by setting the shoulder transverse groove 8, can improve the vulcanization efficiency of the tire shoulder area, increase the heat dissipation performance of the tire shoulder area, avoid the symptoms caused by shoulder heat generation, and reduce the risk of tire shoulder void.

[0044] In some embodiments, the ratio of the width a of the shoulder tread block 7 to the width b of the tread block 2 is 1.4:1. At the same time, the rounded corner design at the edge of the tire shoulder can effectively prevent abnormal wear on the tire shoulder during the steering process, reduce tire wear, and improve tire life and anti-skid performance.

[0045] This utility model also provides a tire, including the above-mentioned all-steel radial truck tire tread pattern. The tire tread is composed of ten equal parts of movable mold, and the tire tread pattern pitch is 40 pitches.

[0046] 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.

[0047] 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.
