Description

Technical Field

[0001] This utility model relates to the field of automotive tire tread technology, specifically a high-performance tread pattern structure for heavy-duty all-steel radial tires. Background Technology

[0002] With the rapid development of transportation vehicles, consumers' demand for tires is increasing, and their requirements for various tire performance aspects are becoming more stringent. For example, consumers expect tires to have higher load-bearing capacity, better heat dissipation, higher wear resistance, and better noise reduction performance.

[0003] Some tires on the market still have the problem of stone trapping. This is because the tire tread design did not fully consider the risk of stones trapping in the tread grooves or did not have an effective anti-stone trapping structure. As a result, it is difficult to throw stones out during driving, causing stones to embed in the bottom of the grooves. The stones are repeatedly squeezed during driving, which may cut the bottom rubber of the grooves, leading to damage such as groove cracks and tread chipping, shortening the normal service life of the tire. Secondly, some tires on the market have a tread pattern with equal pitch design, which creates a natural frequency during tire driving, resulting in greater tire noise at high speeds. Therefore, it affects ride comfort and seriously limits its application range.

[0004] Based on this, this application proposes a new high-performance tread pattern structure for heavy-duty all-steel radial tires. Utility Model Content

[0005] The purpose of this invention is to provide a high-performance tread pattern structure for heavy-duty all-steel radial tires, which is aesthetically pleasing, improves the tire's load-bearing capacity, ensures excellent water drainage and stone-proof performance as well as quietness, reduces the risk of stone trapping, improves the reliability of vehicles driving on mixed road surfaces, and solves current tire grip, grooving, stone trapping, and noise problems.

[0006] To solve the above-mentioned technical problems, this utility model provides a high-performance heavy-duty all-steel radial tire tread pattern structure, including two crown pattern longitudinal grooves and two shoulder pattern longitudinal grooves extending circumferentially along the tread. A central tread strip is provided between the two crown pattern longitudinal grooves. The central tread strip is divided into several central tread blocks by several parallel transverse steel plates. A crown pattern strip is provided between adjacent crown pattern longitudinal grooves and shoulder pattern longitudinal grooves. The crown pattern strip is divided into several crown pattern blocks by several parallel transverse steel plates. A shoulder pattern strip is provided on the outer side of each shoulder pattern longitudinal groove, and several heat dissipation holes are provided on the outer side of each shoulder pattern strip.

[0007] Each of the longitudinal grooves of the crown pattern and the longitudinal groove of the shoulder pattern has several biomimetic rope-knot-shaped steel plates arranged on both sides of the outer wall along the circumference of the tread. The biomimetic rope-knot-shaped steel plates between the two longitudinal grooves of the crown pattern are located at the two sides of the edge of each central tread block. The biomimetic rope-knot-shaped steel plates between the longitudinal grooves of the crown pattern and the longitudinal grooves of the shoulder pattern are located at the two sides of the edge of each crown pattern block. The biomimetic rope-knot-shaped steel plates on the outer side of the longitudinal grooves of the shoulder pattern are located on the shoulder tread strip. Several linear anti-stone lines are arranged on the inner sides of the two longitudinal grooves of the crown pattern and the two longitudinal grooves of the shoulder pattern along the circumference of the tread, and the side close to the biomimetic rope-knot-shaped steel plates is set as a smooth slope.

[0008] Furthermore, both the first and second transverse steel sheets have a wavy shape in the middle and straight lines at both ends;

[0009] The two ends of the first transverse steel plate are respectively connected to the two longitudinal curved grooves of the crown pattern, and are not connected to the biomimetic rope-shaped steel plate. The two ends of the second transverse steel plate are respectively connected to the longitudinal curved groove of the crown pattern and the longitudinal curved groove of the shoulder pattern, and are not connected to the biomimetic rope-shaped steel plate.

[0010] Furthermore, several of the central tread blocks are arranged alternately along the circumference of the tread with two widths, L / M, wherein the number of L and M pitches is 35-45, L=42-50mm, and M=35-42mm.

[0011] Furthermore, each of the crown pattern longitudinal grooves and each of the shoulder pattern longitudinal grooves is a variable-angle groove wall with an inverted arc bottom to prevent stone damage;

[0012] Along the depth direction of the tread groove, there is a stone-proof groove at the bottom of the groove. The angle between the groove wall above the stone-proof groove and the tread plane changes continuously, with the angle ranging from 99° to 112°.

[0013] Furthermore, along the depth direction of the patterned groove, a stone-proof step is set at the knot of the biomimetic rope-shaped steel sheet, and the stone-proof step is set at 1 / 3 of the depth of the patterned groove. The groove wall below the stone-proof step is a smooth slope, and the bottom of the stone-proof groove is a full arc.

[0014] Furthermore, several biomimetic rope-shaped steel plates are evenly distributed along the circumferential direction of the tread, and several biomimetic rope-shaped steel plates are staggered and symmetrically arranged along the axial direction of the tread. The bottom of the biomimetic rope-shaped steel plates extends to 2 / 3 of the depth of the longitudinal groove of the crown pattern or the longitudinal groove of the shoulder pattern.

[0015] Furthermore, each of the linear anti-stone lines has a width of 1 mm and a thickness of 2.5 mm, and adjacent linear anti-stone lines are spaced 1 mm apart.

[0016] Furthermore, the biomimetic rope-shaped steel sheets on several central tread blocks are staggered left and right along the circumference of the tire tread, each biomimetic rope-shaped steel sheet is located at the edge of the central tread block, and the edge of the biomimetic rope-shaped steel sheet is not connected to the adjacent transverse steel sheet one or transverse steel sheet two.

[0017] Furthermore, the heat dissipation holes are conical, and are distributed circumferentially on the shoulder tread strips, with the same number of holes distributed along the tire circumference as the central tread blocks.

[0018] Furthermore, the shoulder pattern strip is a single, solid shoulder pattern block.

[0019] The beneficial effects of this utility model are:

[0020] 1. The present invention provides a high-performance heavy-duty all-steel radial tire tread pattern structure with an attractive appearance, which improves the tire's load-bearing capacity, ensures excellent drainage and stone-proof performance and quietness, reduces the risk of stone trapping, improves the reliability of vehicles driving on mixed roads, and solves the current problems of tire grip, groove cracking, stone trapping, and noise.

[0021] Specifically, the design of two crown tread longitudinal grooves and two shoulder tread longitudinal grooves enhances the tire's driving force during vehicle operation, while also providing excellent drainage performance. This allows the tire to quickly drain water between the tire and the ground, reducing the risk of slippage and improving the vehicle's handling and stability on wet and slippery surfaces.

[0022] The design of alternating horizontal steel plates 1, 2, and biomimetic rope knot-shaped steel plates enhances the tire's grip performance, making driving safer and more reliable. The biomimetic rope knot-shaped steel plates are inspired by the biomimetic design of hemp rope winding, making the pattern more simple and beautiful.

[0023] The integrated design of the shoulder tread strip enhances the uniformity of ground pressure distribution, improves shoulder rigidity and aesthetics, effectively prevents the tread blocks from creeping during driving, minimizes tread block deformation, thereby reducing rolling resistance and reducing uneven tire wear. Combined with the tapered heat dissipation holes on the shoulder, it reduces heat generation on the tire shoulder, thus reducing the proportion of shoulder gaps that are prone to occur during long-term high-speed driving, and the overall structure is more aesthetically pleasing.

[0024] 2. This utility model utilizes a variable-angle trench wall with a curved longitudinal groove and an inverted arc anti-stone structure at the bottom of the trench, combined with an anti-stone line structure evenly distributed on the side. The linear anti-stone lines form a barrier, restricting stones from continuing to penetrate to the bottom of the trench and thus preventing them from damaging the bottom rubber. The variable-angle trench wall makes it easier for stones to be discharged, effectively reducing stone trapping, improving the tire's stone discharge performance, and enhancing the tire's impact resistance and puncture resistance.

[0025] 3. The central tread block and the crown tread block of this utility model are arranged in a staggered manner, which can disperse the vibration frequency generated when the tread block contacts the ground, avoid noise superposition, thereby reducing tire noise during driving and improving driving comfort;

[0026] 4. This utility model uses a design that features biomimetic rope-knot-shaped steel sheets located on both sides of each pattern block, staggered from each other and not connected to the first and second transverse steel sheets. This design can increase tire grip, provide some anti-skid effect, and also ensure a certain level of aesthetics.

[0027] 5. This utility model uses biomimetic rope-shaped steel sheets that are staggered along the axial direction at different positions to break the water film more efficiently, allowing the tire to contact the ground more directly, increasing friction and reducing slippage;

[0028] 6. The transverse steel sheet one and transverse steel sheet two of this utility model adopt a steel sheet structure with different depths. This design can not only ensure the rigidity of each tread block and reduce the creep of the tread block, but also ensure the tire's grip through the combination of the above steel sheets in the later stages of tire wear.

Detailed Implementation

[0038] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] In one specific embodiment of this utility model, such as Figure 1-7 As shown, a high-performance heavy-duty all-steel radial tire tread pattern structure includes two crown pattern longitudinal grooves 1 and two shoulder pattern longitudinal grooves 2 extending circumferentially along the tread. A central pattern strip 3 is provided between the two crown pattern longitudinal grooves 1. The central pattern strip 3 is divided into several central pattern blocks 5 by several parallel transverse steel plates 4. A crown pattern strip 6 is provided between adjacent crown pattern longitudinal grooves 1 and shoulder pattern longitudinal grooves 2. The crown pattern strip 6 is divided into several crown pattern blocks 8 by several parallel transverse steel plates 7. A shoulder pattern strip 9 is provided on the outer side of each shoulder pattern longitudinal groove 2. A number of heat dissipation holes 10 are provided on the outer side of each shoulder pattern strip 9.

[0040] Each crown longitudinal groove 1 and each shoulder longitudinal groove 2 has several biomimetic rope-knot-shaped steel plates 11 arranged on both sides of the outer wall along the circumference of the tread. The biomimetic rope-knot-shaped steel plates 11 between the two crown longitudinal grooves 1 are located at the two sides of the edge of each central tread block 5. The biomimetic rope-knot-shaped steel plates 11 between the crown longitudinal groove 1 and the shoulder longitudinal groove 2 are located at the two sides of the edge of each crown tread block 8. The biomimetic rope-knot-shaped steel plates 11 on the outer side of the shoulder longitudinal groove 2 are located on the shoulder tread strip 9. Several linear anti-stone lines 12 are arranged on the inner sides of the two crown longitudinal grooves 1 and the two shoulder longitudinal grooves 2 along the circumference of the tread, and the side close to the biomimetic rope-knot-shaped steel plates 11 is set as a smooth inclined surface 13.

[0041] This utility model features a high-performance all-steel radial tire tread pattern structure with a simple and elegant appearance. It improves the tire's load-bearing capacity, ensures excellent water drainage and stone-proof performance as well as quietness, reduces the risk of stone trapping, and enhances the reliability of vehicles driving on mixed road surfaces. It also solves current tire grip, groove cracking, stone trapping, and noise problems.

[0042] Specifically, the design of two longitudinal grooves on the crown and two longitudinal grooves on the shoulder of this embodiment enhances the tire's driving force during vehicle operation and provides excellent drainage performance. This allows for the rapid removal of water accumulated between the tire and the ground, reducing the risk of slippage and improving the vehicle's handling and stability on slippery surfaces. In this embodiment, the center tread block 5 and the crown tread block 8 are arranged in a staggered manner, which disperses the vibration frequency generated when the tread blocks contact the ground, preventing noise superposition and thus reducing tire noise during driving and improving driving comfort.

[0043] Specifically, in this embodiment, the design of the alternating arrangement of transverse steel sheet 4, transverse steel sheet 7, and biomimetic rope knot steel sheet 11 enhances the tire's grip performance, making driving safer and more reliable. Here, the biomimetic rope knot steel sheet 11 is based on the biomimetic design of hemp rope winding, making the pattern more simple and beautiful.

[0044] Each crown tread longitudinal groove 1 and each shoulder tread longitudinal groove 2 has several biomimetic rope-knot-shaped steel pieces 11 arranged on both sides of the outer wall along the circumferential direction of the tread. The biomimetic rope-knot-shaped steel pieces 11 are evenly distributed along the circumferential direction of the tread, and the biomimetic rope-knot-shaped steel pieces 11 are staggered and symmetrically arranged along the axial direction of the tread. The bottom of the biomimetic rope-knot-shaped steel pieces 11 extends to 2 / 3 of the depth of the crown tread longitudinal groove 1 or the shoulder tread longitudinal groove 2. Through the design of the biomimetic rope-knot-shaped steel pieces 11 staggered in different positions, the water film can be broken more efficiently, allowing the tire to contact the ground more directly, increasing friction and reducing slippage.

[0045] The design incorporates several linear anti-stone lines 14 arranged circumferentially along the inner sides of the two crown longitudinal grooves 1 and the two shoulder longitudinal grooves 2, forming a barrier to prevent stones from penetrating further into the grooves.

[0046] Specifically, in this embodiment, the middle of both the first transverse steel sheet 4 and the second transverse steel sheet 7 is wavy, and both ends are straight. The two ends of the first transverse steel sheet 4 are respectively connected to two longitudinal curved grooves 1 of the crown pattern and are not connected to the bionic rope knot-shaped steel sheet 11. The two ends of the second transverse steel sheet 7 are respectively connected to the longitudinal curved grooves 1 of the crown pattern and the longitudinal curved grooves 2 of the shoulder pattern and are not connected to the bionic rope knot-shaped steel sheet 11. In this embodiment, the wavy shape is S-shaped and is composed of two arc radii R3, which can break the water film and improve the wet grip performance of the tire. Of course, in other embodiments, the radius size is adjusted according to actual needs.

[0047] In this embodiment, the transverse steel sheet 4 and the transverse steel sheet 7 adopt a steel sheet structure with different depths. This design can not only ensure the rigidity of each tread block and reduce the creep of the tread block, but also ensure the tire's grip through the combination of the above steel sheets in the later stages of tire wear. In addition, combined with the design of the biomimetic rope knot-shaped steel sheet 11, the tire has a certain anti-skid performance and exhibits stable handling performance on wet and slippery roads, making driving safer and more reliable.

[0048] like Figure 2 As shown, in this embodiment, each longitudinal groove 1 of the crown pattern and each longitudinal groove 2 of the shoulder pattern are variable-angle groove walls with a chamfered bottom anti-stone structure. Specifically, along the depth direction of the tread groove (from the tread surface to the bottom of the groove), an anti-stone groove 14 is provided at the bottom of the groove. The angle between the groove wall above the anti-stone groove 14 (the side where the tread block connects to the anti-stone groove) and the tread plane changes continuously, ranging from 99° to 112°. Here, the variable-arc groove wall makes it easier for stones to be discharged, effectively reducing the phenomenon of stone trapping, improving the tire's stone discharge performance, and enhancing the tire's impact resistance and puncture resistance.

[0049] like Figure 3 As shown, along the depth direction of the tread groove, a stone-proof step 15 is set at the knot of the biomimetic rope-shaped steel sheet 11, and the stone-proof step 15 is set at 1 / 3 of the depth of the tread groove. The groove wall below the stone-proof step 15 is a smooth slope, and the bottom of the stone-proof groove 14 is a full arc. The stone-proof step 15 can form a barrier to restrict stones from continuing to penetrate into the bottom of the stone-proof groove 14, preventing stones from making full contact with the bottom of the groove, thereby cutting the bottom rubber. The design of the variable arc groove wall can make it easier for stones to be discharged, effectively reducing the phenomenon of stones getting stuck, improving the stone discharge performance of the tire, and enhancing the tire's impact resistance and puncture resistance.

[0050] like Figure 4 The image shown is a cross-sectional view of the biomimetic rope-knot-shaped steel sheet 11; as shown... Figure 5 The image shown is a cross-sectional view of the transverse steel sheet 4, which uses a steel sheet structure with varying depths.

[0051] Specifically, in this embodiment, each linear anti-stone line 12 has a width of 1mm and a thickness of 2.5mm. Adjacent linear anti-stone lines are spaced 1mm apart. The linear anti-stone lines can form a barrier to restrict stones from continuing to penetrate into the bottom of the ditch. Combined with the anti-stone ditch 14, it can prevent stones from making full contact with the bottom of the ditch, thereby damaging the bottom adhesive.

[0052] Specifically, several biomimetic rope-shaped steel pieces 11 are evenly distributed along the circumferential direction of the tread, and several biomimetic rope-shaped steel pieces 11 are staggered and symmetrically arranged along the axial direction of the tread. The bottom of the biomimetic rope-shaped steel pieces 11 extends to 2 / 3 of the depth of the longitudinal groove 1 of the crown pattern or the longitudinal groove 2 of the shoulder pattern.

[0053] Specifically, in this embodiment, several biomimetic rope-knot-shaped steel pieces 11 on the central tread blocks 5 are staggered left and right along the circumference of the tire tread. Each biomimetic rope-knot-shaped steel piece 11 is located at the edge of the central tread block 5, and the edge of the biomimetic rope-knot-shaped steel piece 11 is not connected to the adjacent transverse steel piece 4 or transverse steel piece 7. This design can increase the tire grip and also play a certain role in preventing sideslip, while also ensuring a certain degree of aesthetics.

[0054] like Figure 6 As shown, in this embodiment, the heat dissipation holes 10 are conical, and the heat dissipation holes 10 are distributed circumferentially on the shoulder tread strip 9, and the number of them is the same as that of the central tread block 5 along the tire circumference; the shoulder tread strip 9 is a single shoulder tread block; the single-piece design of the shoulder tread strip 9 enhances the uniformity of ground pressure distribution, improves the rigidity and aesthetics of the shoulder, effectively prevents the creep of the shoulder tread block during driving, and makes the tread block deformation small, thereby reducing rolling resistance and reducing tire wear problems; the design of the conical heat dissipation holes on the shoulder reduces the heat generation phenomenon on the tire shoulder, thereby reducing the proportion of shoulder gaps that are easy to occur during long-term high-speed driving, and the overall structure is more beautiful and elegant.

[0055] like Figure 7 As shown, there are two schematic diagrams illustrating the alternating arrangement of center tread blocks with two widths L / M along the circumference of the tire tread. In this embodiment, several center tread blocks 5 are arranged alternately with two widths L / M along the circumference of the tire tread, wherein the number of L and M pitches is 35-45, L=42-50mm, and M=35-42mm. Through the combination of four longitudinal straight grooves and the alternating arrangement of center tread block pitches, the noise of the tire tread during driving is effectively reduced, driving comfort is improved, the tire driving force during vehicle driving is stronger, and it also has excellent drainage performance and quiet performance. It can quickly drain water between the tire and the ground, reduce the risk of slippage, and improve the vehicle's handling and stability on wet and slippery roads, as well as the quietness during normal driving.

[0056] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
