Description

Technical Field

[0001] This utility model belongs to the field of tire tread technology, and more specifically, relates to a tread pattern reinforcing rib assembly for a tire wear-resistant enhancement device. Background Technology

[0002] As the only component of a vehicle in contact with the road surface, the tire's performance directly affects driving safety and comfort. The tire tread grooves play a crucial role in tire design, including drainage, heat dissipation, and enhanced grip. However, in actual use, the rubber structure within the tire tread grooves, due to long-term friction with the road surface and exposure to complex stress and temperature changes, is prone to rapid wear. This is especially true during high-speed driving, frequent braking, or driving in adverse road conditions, where the wear rate of the tread grooves is even faster. When the tread groove depth wears below the safe limit, the tire's drainage performance drops sharply, making it prone to hydroplaning in rainy or snowy weather, significantly increasing braking distance, and seriously threatening driving safety. Meanwhile, wear on the tread grooves also leads to a decrease in tire grip and a deterioration in vehicle handling. To solve this problem, existing technologies mainly employ methods such as increasing the hardness of the tire rubber, optimizing the tread groove design, and adding wear-resistant fillers. However, these methods often come at the cost of sacrificing tire comfort and quietness, or increasing tire manufacturing costs. Some other solutions propose installing metal or hard plastic reinforcements inside the tread grooves, but these reinforcements often suffer from problems such as insecure installation, easy detachment, poor compatibility with tire rubber, or abnormal wear during use. Therefore, there is an urgent need to develop a tire tread groove reinforcement device that is simple in structure, securely installed, has excellent wear resistance, and is reasonably priced. Utility Model Content

[0003] In view of this, the present invention provides a tread pattern reinforcing rib assembly for a tire wear-resistant enhancement device, which can solve the problem that in the long-term use of tires, the rubber structure in the tread pattern grooves is prone to rapid wear due to continuous friction with the road surface, resulting in a shallower tread groove depth. This significantly reduces the tire's drainage performance, grip, and braking performance, seriously affecting driving safety. At the same time, it shortens the tire's service life and increases the user's operating costs. Existing tread groove reinforcement solutions often have technical problems such as insecure installation, easy detachment, insufficient wear resistance, or complex and costly structures.

[0004] This utility model is implemented as follows:

[0005] This utility model provides a tread pattern reinforcing rib assembly for a tire wear-resistant enhancement device, used to be embedded in the tread pattern groove of a tire. It includes a rib body, an embedding base, and a transition section connecting the rib body and the embedding base. The rib body has a wave-shaped raised structure. The bottom contour of the embedding base matches the bottom contour of the tire tread pattern groove. The transition section extends upward from the top of the embedding base and gradually transitions to the rib body. The top of the rib body has multiple wear-resistant ridges arranged radially along the tire, and these ridges are spaced apart circumferentially along the tire. When the tread pattern reinforcing rib assembly is embedded in the tread groove, the top of each wear-resistant ridge is flush with or slightly higher than the outer surface of the tire tread. Locking flanges are provided on both sides of the embedding base, and these locking flanges are interference-fitted with the sidewalls of the tread groove.

[0006] The technical effects of the tread pattern reinforcing rib assembly of the tire wear-resistant enhancement device provided by this utility model are as follows: By setting multiple wear-resistant ridges spaced along the tire circumference at the top of the rib body, the wear-resistant ridges can directly contact the road surface and withstand wear after the tread pattern reinforcing rib assembly is embedded in the tread groove, effectively extending the tire's service life; at the same time, the locking flanges set on both sides of the embedded base are interference-fitted with the sidewalls of the tread groove, ensuring that the reinforcing rib assembly does not loosen or fall off when the tire rotates at high speed and is subjected to complex road surface stress, thus ensuring the stability and reliability of the device; the wavy raised structure of the rib body increases the contact area with the road surface, improving the tire's grip and water drainage performance.

[0007] Based on the above technical solution, the tread pattern reinforcing rib assembly of the tire wear-resistant enhancement device of this utility model can be further improved as follows:

[0008] The height of the wear-resistant ridge along the radial direction of the tire is greater than the peak height of the main rib body.

[0009] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by making the height of the wear-resistant ridge along the radial direction of the tire greater than the peak height of the main body of the rib, the wear-resistant ridge first contacts the road surface and bears the main wear during tire use. When the wear-resistant ridge wears to a certain extent, the peak structure of the main body of the rib begins to contact the road surface, forming a secondary wear-resistant protection mechanism. This significantly extends the service life of the reinforcing rib assembly and provides users with an intuitive basis for judging the degree of wear, facilitating timely replacement or maintenance.

[0010] Furthermore, the cross-section of the transition section is trapezoidal, the width of the transition section gradually decreases from the embedded base towards the main body of the rib, and the angle between the two sides of the transition section and the two sides of the embedded base is 100° to 140°.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a transition section with a trapezoidal cross-section and a gradually decreasing width, a smooth transition from the embedded base to the main body of the rib is achieved, which effectively disperses the stress concentration generated at the connection point when the tire bears impact load, and avoids the fracture or cracking of the reinforcing rib assembly due to stress concentration; the included angle between the two sides of the transition section and the side of the embedded base is set to 100° to 140°, which not only ensures the structural strength, but also facilitates the installation and disassembly of the reinforcing rib assembly, thereby improving the practicality and maintainability of the device.

[0012] Furthermore, the wear-resistant ridge is in the shape of a triangular pyramid, and the bottom of the wear-resistant ridge is smoothly connected to the top of the rib body.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by designing the wear-resistant ridge into a triangular pyramid shape, the top of the ridge has a small contact area, which can generate a large unit area pressure when the tire contacts the road surface, effectively breaking the water film on the wet and slippery road surface and improving the tire's anti-skid performance in rainy and snowy weather conditions; the bottom of the triangular pyramid-shaped wear-resistant ridge is smoothly connected to the top of the main body of the rib, avoiding sharp structural abrupt changes, reducing stress concentration, and improving the fatigue resistance of the wear-resistant ridge and the durability of the overall structure.

[0014] Furthermore, the spacing between two adjacent wear-resistant ridges varies periodically along the tire circumference, and the period of variation of the spacing corresponds to the pitch of the tire tread grooves.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by making the spacing between two adjacent wear-resistant ridges periodically varied along the tire circumference, and making the spacing variation period correspond to the tire tread pitch, the noise generated by the tire at high speed is effectively reduced, and the driving comfort of the vehicle is improved; the periodically varied spacing distribution disperses the impact force when the tire contacts the road surface in time and space, reduces tire vibration and resonance, and extends the service life of the tire and vehicle suspension system.

[0016] Furthermore, the wave-shaped protrusion structure of the main body of the rib includes multiple peaks and multiple troughs, the radius of the top arc of the peak is smaller than the radius of the bottom arc of the trough, and the transition surface between the peak and the trough is a smooth curved surface.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by making the radius of the arc at the top of the wave crest of the rib body's wavy convex structure smaller than the radius of the arc at the bottom of the wave trough, the wave crest part has better wear resistance and contact stability with the road surface, while the wave trough part provides a larger capacity for drainage and mud removal; the smooth curved surface transition between the wave crest and the wave trough avoids stress concentration and crack initiation, improves the overall strength and fatigue resistance of the rib body, and at the same time, the smooth curved surface transition reduces the accumulation of dust and debris, facilitating the self-cleaning of the reinforcing rib assembly.

[0018] Furthermore, the locking flange protrudes outward from the side of the embedded base, and the protrusion length of the locking flange increases in a stepped manner along the length direction of the embedded base. A stepped structure is formed between the top surface of the locking flange and the top surface of the embedded base.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by making the protruding length of the locking flange increase in a stepped manner along the length direction of the embedded base, the progressive locking of the reinforcing rib assembly in the tread groove is achieved, making the installation process smoother. At the same time, when the tire is subjected to complex stress, the stepped distribution of the locking flange can provide differentiated locking forces at different positions, effectively resisting the axial and radial displacement of the reinforcing rib assembly. The stepped structure formed between the top surface of the locking flange and the top surface of the embedded base increases the contact area with the sidewall of the tread groove, further improving the locking reliability.

[0020] Furthermore, the bottom of the embedded base is provided with multiple positioning protrusions, which are evenly distributed along the length of the embedded base, and the positioning protrusions are hemispherical or cylindrical in shape.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting multiple positioning protrusions evenly distributed along the length direction at the bottom of the embedded base, the reinforcing rib assembly can be accurately positioned at the bottom of the tread groove during installation, avoiding performance degradation caused by installation misalignment or improper positioning; the positioning protrusions are hemispherical or cylindrical in shape, forming point contact or line contact with the bottom of the tread groove, reducing contact stress and preventing damage to the bottom of the tread groove caused by local stress concentration. At the same time, the setting of positioning protrusions increases the friction between the reinforcing rib assembly and the tire, improving the stability of the device.

[0022] Furthermore, the tread pattern reinforcing rib assembly is made of polyurethane elastomer material or silicone rubber material, and the rib body, transition section and embedded base are integrally molded structures.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by using polyurethane elastomer material or silicone rubber material to make the tread pattern reinforcing rib assembly, the device is ensured to have good elasticity and wear resistance, which can adapt to the deformation requirements of the tire under different road conditions and avoid local stress concentration and cracking of the tire due to excessive material rigidity; the one-piece molding structure eliminates the connection interface between the main body of the rib, the transition section and the embedded base, avoiding stress concentration and fatigue failure at the interface, improving the overall strength and service life of the reinforcing rib assembly, while simplifying the manufacturing process and reducing production costs.

[0024] Furthermore, the ratio of the length of the main body of the rib along the tire circumference to the length of the embedded base along the tire circumference is 3:5 to 4:5, and the ratio of the height of the transition section along the tire radial direction to the height of the main body of the rib along the tire radial direction is 1:2 to 1:3.

[0025] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the ratio of the length of the main body of the rib along the tire circumference to the length of the embedded base along the tire circumference to 3:5 to 4:5, and the ratio of the height of the transition section along the tire radial direction to the height of the main body of the rib along the tire radial direction to 1:2 to 1:3, the dimensions of each part of the reinforcing rib assembly are optimized and matched. This ensures that the main body of the rib has sufficient length to provide wear-resistant protection and grip, and also ensures that the embedded base has sufficient length to achieve stable locking. At the same time, the reasonable height of the transition section ensures the smoothness of stress transmission and avoids material waste and weight increase caused by an excessively high transition section.

[0026] Compared with existing technologies, the beneficial effects of the tread pattern reinforcing rib assembly of the tire wear-resistant enhancement device provided by this utility model are as follows: This utility model effectively solves the technical problem of rapid wear of tire tread grooves by embedding a specially designed tread pattern reinforcing rib assembly into the tire tread grooves, significantly extending the service life of the tire. The wear-resistant ridge on the top of the rib body cooperates with the locking flange embedded in the base, ensuring the stable installation of the reinforcing rib assembly and achieving excellent wear resistance. The wavy raised structure of the rib body not only increases the contact area with the road surface and improves the tire's grip, but also optimizes the drainage capacity of the tread grooves, improving the tire's driving safety on wet and slippery roads. The trapezoidal structure of the transition section is designed with... The design effectively disperses stress concentration, preventing breakage or cracking of the reinforcing rib assembly during use. The triangular pyramidal shape of the wear-resistant ridges allows them to withstand wear while breaking through the water film, further enhancing anti-slip performance. The periodically varying spacing of the wear-resistant ridges reduces tire noise and improves driving comfort. The stepped locking flanges and bottom positioning protrusions together ensure precise positioning and stable installation of the reinforcing rib assembly. The one-piece molded polyurethane elastomer or silicone rubber material not only guarantees the device's elasticity and wear resistance but also simplifies the manufacturing process. The optimized size proportions achieve the best match of the functions of each part. This utility model has a simple and reasonable structure, is easy to install, and has low cost, making it widely applicable. Attached Figure Description

[0035] In the above technical solution, the height of the wear-resistant ridge along the radial direction of the tire is greater than the peak height of the rib body.

[0044] The following is a specific embodiment 1 of this utility model: This embodiment provides a tread pattern reinforcing rib assembly for passenger car tires. The total length of the assembly is 80mm to 120mm. The main body of the rib adopts a wave-shaped raised structure, including 5 to 7 complete peaks and troughs. The top arc radius of each peak is 1.5mm to 2.5mm, the bottom arc radius of each trough is 3mm to 5mm, the vertical height difference between the peaks and troughs is 3mm to 5mm, and a smooth parabolic surface transition is used between the peaks and troughs with a radius of 8mm to 12mm to ensure smooth stress transmission. Along the top of the rib body... The tire has 8 to 12 wear-resistant ridges radially arranged. These ridges are triangular pyramidal in shape, with each ridge having a base length of 4mm to 6mm, a height of 2mm to 3mm, and a apex angle of 60° to 80°. The spacing between adjacent ridges varies periodically, ranging from 6mm to 10mm, with a cycle of 3 to 4 ridges per group. This spacing matches the pitch of the tire tread grooves. The bottom profile of the embedded base is designed to match the U-shaped or V-shaped cross-section of the tread groove bottom. The embedded base has a width of 8mm to 12mm and a thickness of 2mm to 4mm, and has 3 to 5 positioning protrusions on its bottom. The positioning protrusions are hemispherical with a radius of 1mm to 1.5mm, evenly distributed along the center line of the bottom of the embedded base. Each side of the embedded base has a locking flange, protruding outwards by 0.5mm to 1mm to form an interference fit. The protruding length of the locking flange is divided into 3 to 4 segments along the length of the embedded base, with each segment increasing in length by 0.1mm to 0.2mm, forming a stepped distribution. The step height between the top surface of the locking flange and the top surface of the embedded base is 1mm to 2mm. The transition section extends upwards from the top of the embedded base, with a trapezoidal cross-section. The width of the bottom edge is the same as the width of the embedded base, and the top edge... The width is the same as the bottom width of the main rib body, the height of the transition section is 4mm to 6mm, and the included angle between the two sides and the side of the embedded base is 120°, forming a smooth transition. The entire tread pattern reinforcing rib assembly is made of polyurethane elastomer material with a Shore hardness of 85A to 95A, and is integrally molded by injection molding process. The tensile strength of the material reaches 30MPa to 40MPa, the elongation at break is 400% to 600%, and the wear resistance is excellent. In actual use, the reinforcing rib assembly is embedded in the longitudinal tread groove of the tire tread, with an embedding depth of 80% to 90% of the tread groove depth. The top of the wear-resistant ridge protrudes 0.The wear-resistant ridges, ranging from 5mm to 1mm, are securely fixed after installation via an interference fit between the locking flange and the sidewall of the tread groove. During tire rolling, the wear-resistant ridges first contact the road surface, bearing the main wear. The wavy rib body deforms in a coordinated manner when the tire deforms, avoiding stress concentration. The trapezoidal structure of the transition section effectively disperses impact loads, and the positioning protrusions ensure accurate positioning of the reinforcing rib assembly within the tread groove. The entire device operates stably and reliably, significantly extending tire life and improving driving safety.

[0045] The following is another specific embodiment 2 of this utility model: This embodiment 2 is an improvement on embodiment 1 for off-road vehicle tires. The number of ridges in the main body of the rib is reduced to 3 to 5, but the height of each ridge is increased to 5mm to 7mm to accommodate the deeper tread grooves of off-road tires. The number of wear-resistant ridges is correspondingly reduced to 6 to 8, but the bottom edge length of each wear-resistant ridge is increased to 6mm to 8mm and the height is increased to 3mm to 4mm to withstand greater impact loads. The width of the embedded base is increased to 12mm to 16mm and the thickness is increased to 3mm to 5mm. The protrusion of the locking flange is increased to 1mm to 1.5mm to accommodate the larger sidewall spacing of the tread grooves of off-road tires. The material selected is polyurethane elastomer with a Shore hardness of 90A to 100A to provide better impact resistance and wear resistance. This embodiment is particularly suitable for off-road vehicles that frequently drive on gravel roads, muddy roads and other harsh conditions, and can effectively protect the tire tread grooves and extend the service life of the tire in harsh environments.

[0046] The following is another specific embodiment 3 of this utility model: This embodiment 3 is an optimized design for winter tires based on embodiment 1. The shape of the wear-resistant ridge is changed from a triangular pyramid to a pyramid with micro-cutting edges. Two to three cutting edges with a depth of 0.3mm to 0.5mm are added to the side of each wear-resistant ridge. These cutting edges form an angle of 30° to 45° with the edge of the wear-resistant ridge to provide stronger grip on icy and snowy roads. Transverse micro-textures with a depth of 0 are added to the bottom of the trough of the main body of the rib. The tires are 5mm to 1mm thick with a spacing of 2mm to 3mm to enhance drainage and snow removal capabilities. The material used is silicone rubber with excellent low-temperature performance and a Shore hardness of 70A to 80A. It can maintain good elasticity even at a low temperature of -40℃. The number of positioning protrusions embedded in the base is increased to 5 to 7 to ensure accurate positioning even when the tire hardens at low temperatures. This embodiment is particularly suitable for winter tires used in cold regions with frequent snow and ice weather. It can significantly improve the braking performance and handling stability of the tires on icy and snowy roads, and ensure driving safety in winter.

[0047] Specifically, the principle of this utility model is as follows: the tread pattern reinforcing rib assembly forms an interference fit with the sidewall of the tire tread groove through the locking flange embedded in the base, achieving a stable installation of the device. The radial pressure generated by the interference fit ensures that the reinforcing rib assembly will not loosen or fall off when the tire rotates at high speed and is subjected to complex road impacts. When the wave-shaped raised structure of the rib body comes into contact with the road surface, the crests bear the wear first, while the troughs form drainage channels, effectively improving the tire's drainage performance and preventing hydroplaning. The wear-resistant ridge set at the top of the rib body has a radial height greater than the crest height, allowing the wear-resistant ridge to bear the main wear in the early stages of use, forming the first level of wear protection. When the wear-resistant ridge wears down, the crest structure of the rib body continues to provide wear protection, forming the second level of protection mechanism. This graded wear-resistant design significantly extends the service life of the device. The triangular pyramid shape of the wear-resistant ridge gives it a smaller contact area at the top. When in contact with the road surface, it generates a large pressure per unit area, which can effectively break the water film on wet and slippery surfaces and improve anti-skid performance. The trapezoidal structure design of the transition section allows stress to be gradually dispersed as it is transferred from the embedded base to the main body of the rib, avoiding abrupt changes and concentrations of stress at the connection points, and preventing the generation and propagation of fatigue cracks. The stepped distribution of the locking flange allows the reinforcing rib assembly to obtain differentiated locking forces at different axial positions, which can adapt to the deformation of the tire under different working conditions. The positioning protrusion at the bottom ensures accurate positioning of the reinforcing rib assembly by contacting the bottom of the tread groove, avoiding excessive local stress caused by installation misalignment. The selection of polyurethane elastomer or silicone rubber materials ensures that the reinforcing rib assembly has an elastic modulus similar to that of tire rubber, which can coordinate deformation and avoid stress concentration caused by rigidity differences. The optimized size ratio design ensures that the main body of the rib, the transition section and the embedded base can fully perform their respective functions, achieving the optimization of overall performance.

[0048] The specific operation or use method of this utility model is as follows: First, fix the tire on the workbench, so that the tread groove of the tread pattern reinforcing rib assembly to be installed is in an easy-to-operate position. Thoroughly clean the inside of the tread groove with a cleaning agent to remove dust, oil, and debris, and dry it with compressed air. Then, select a tread pattern reinforcing rib assembly of appropriate size according to the length of the tread groove. Align one end of the reinforcing rib assembly with the tread groove inlet, so that the positioning protrusion at the bottom of the embedded base is aligned with the bottom of the tread groove. Slowly push the reinforcing rib assembly in along the extension direction of the tread groove. During the pushing process, the locking flanges on both sides of the embedded base will make interference contact with the side wall of the tread groove, generating a certain resistance. At this time, a uniform pushing force needs to be applied to make... The locking flange gradually embeds into the sidewall of the tread groove. After the reinforcing rib assembly is fully pushed into the tread groove, check whether the wear-resistant ridge at the top of the rib body is flush with or slightly higher than the outer surface of the tire tread. If necessary, use a special tool to fine-tune the position of the reinforcing rib assembly to ensure that its installation position is accurate. After installation, the tire can be used normally. During use, the wear-resistant ridge first contacts the road surface and bears wear. When the wear-resistant ridge wears down to the level of the crest of the rib body, it indicates that the reinforcing rib assembly has used about half of its lifespan. At this time, the user can decide whether to replace it as needed. When replacing, simply use a special disassembly tool to pull the reinforcing rib assembly out of the tread groove, clean the tread groove, and then install a new reinforcing rib assembly.
