Technical Field
[0001] This utility model relates to the field of automobile tire technology, and in particular to an anti-slip asymmetric rain tire structure. Background Technology
[0002] In modern transportation, tires, as important wheel components, bear the weight of vehicles and come into contact with the road surface, directly affecting the driving performance of vehicles. Especially in adverse weather conditions such as rain and snow, traditional tires often experience slippery and uncontrollable situations due to the limitations of their structural design. Rain tires, also known as wet tires, are a type of tire specifically designed for rainy or slippery roads. Their structural features are enhanced tread pattern drainage capacity and improved wet grip. Therefore, an anti-slip asymmetric rain tire structure is proposed.
[0003] Existing wet tires generally adopt symmetrical or simple asymmetrical designs. However, in actual use, especially in prolonged heavy rain or water accumulation, when turning on wet or waterlogged roads, the tires' limited drainage capacity and poor grip can easily lead to slippage, seriously affecting driving safety. Furthermore, some existing wet tires have sound-dampening cotton lining the inner wall, which is applied in a ring around the entire tire. When a tire is punctured, repairing the puncture requires peeling off the sound-dampening cotton, causing damage. After repair, because the sound-dampening cotton is a single ring, it cannot be effectively repaired locally. When repairs are needed, the entire strip of sound-dampening cotton must be replaced, resulting in significant costs.
[0004] Therefore, those skilled in the art have provided an anti-slip asymmetric rain tire structure to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing an anti-slip asymmetrical wet tire structure. This structure utilizes sound-absorbing cotton, with multiple small pieces of cotton attached to the inner wall of the wet tire. When a tire is punctured, after removing and repairing the puncture site, only the original sound-absorbing cotton needs to be reattached, avoiding the relatively high cost associated with replacing the entire sound-absorbing cotton strip in traditional methods.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A wet-slip asymmetric rain tire structure includes a tire body assembly, the tire body assembly including a tread, the outer wall of the tread being provided with a tread pattern assembly, the tread pattern assembly including a first annular groove opened in the middle of the outer wall of the tread, a second annular groove opened at both the front and rear ends of the first annular groove, a plurality of oblique drainage grooves being staggered on the inner walls of the front and rear ends of the first annular groove, a plurality of rectangular tread blocks formed by the first annular groove, the second annular groove and the oblique drainage grooves being provided at the front and rear ends of the middle of the outer wall of the tread, a plurality of drainage grooves being opened on the outer wall of the rear end of the second annular groove, a water-cutting tread block being fixedly connected to the middle of the inner bottom surface of the drainage groove, a drainage tread block being provided at the rear end of the tread by the rear end of the second annular groove and the plurality of drainage grooves, a plurality of hook-shaped tread grooves being opened on the inner wall of the front end of the second annular groove, a gripping tread block being provided at the front end of the outer wall of the tread by the front end of the second annular groove and the plurality of hook-shaped tread grooves, and a plurality of sound-absorbing cotton being arranged in an array inside the tire body assembly;
[0008] The above technical solutions can effectively overcome the shortcomings of existing wet tires that are prone to slipping when turning in heavy rain or on flooded roads, and significantly improve driving safety.
[0009] Furthermore, the inner wall of the tread is sequentially provided with a covering layer, a steel belt bundle layer, a stress-absorbing rubber strip, a tire carcass cord layer and an airtight layer, and multiple sound-absorbing cottons are attached to the inner wall of the airtight layer. The sound-absorbing cottons are trapezoidal in design and are made of polyurethane foam.
[0010] By using the above technical solution and designing the sound-absorbing cotton in a trapezoidal shape, if a nail is stuck in the gap between multiple sound-absorbing cotton pieces, the top of the sound-absorbing cotton can be moved directly, thus avoiding the need to remove the sound-absorbing cotton. This can further reduce the later repair costs of the tire.
[0011] Furthermore, the first annular groove is connected to the second annular groove through an inclined drainage groove, and the transverse diameter of the inclined drainage groove at the front end is smaller than the transverse diameter of the inclined drainage groove at the rear end.
[0012] Through the above technical solution, the first annular groove is connected to the second annular groove through the inclined drainage groove. The transverse diameter of the front inclined drainage groove is smaller than that of the rear inclined drainage groove, so that a large amount of water accumulated inside the first annular groove can enter the rear second annular groove and be discharged from the inner drainage structure. This reduces the amount of water discharged when the outside is turning, thereby improving the grip performance.
[0013] Furthermore, the inclined drainage channel at the rear end is a straight through channel, and the two corners of the drainage channel near the second annular channel are both rounded.
[0014] Through the above technical solution, the rear inclined drainage channel and the drainage channel are connected in a straight line, and the two corners of the drainage channel near the second annular channel are designed with arcs. This allows the water inside the inclined drainage channel to flow directly into the drainage channel under the pressure of the vehicle during driving and be discharged. Furthermore, the arcs allow the water inside the inclined drainage channel to carry the water inside the rear second annular channel into the drainage channel when it flows into the drainage channel. The arc design effectively reduces the resistance of water flow. At the same time, it effectively reduces the impact of air inside during daily driving, thus achieving the goal of quietness.
[0015] Furthermore, the outer walls of the plurality of drainage patterned blocks are provided with a plurality of drainage grooves, the drainage grooves are connected to the second annular groove at the rear end, and the longitudinal diameter of the drainage grooves is smaller than the longitudinal diameter of the drainage channel.
[0016] Through the above technical solution, the drainage groove is connected to the second annular groove at the rear end. The longitudinal diameter of the drainage groove is smaller than that of the drainage channel. Therefore, when the vehicle is turning, the drainage groove can effectively work with the water-cutting pattern block to cut the water surface at the water accumulation point, so that the tire can effectively contact the ground.
[0017] Furthermore, the outer wall of each gripping pattern block is provided with multiple gripping grooves, which are connected to the second annular groove at the front end. The longitudinal diameter of the gripping groove is smaller than the longitudinal diameter of the hook-shaped pattern groove.
[0018] Through the above technical solution, the grip groove is connected to the second annular groove at the front end. The longitudinal diameter of the grip groove is smaller than the longitudinal diameter of the hook-shaped groove. This allows the grip groove to improve the overall grip performance of the rain tire while taking into account the drainage effect, thereby avoiding the problem of vehicle sideslip when cornering.
[0019] This utility model has the following beneficial effects:
[0020] 1. This utility model proposes an anti-slip asymmetrical wet tire structure. Through the design of the tread components, multiple rectangular tread blocks are formed by the first annular groove, the second annular groove, and the staggered oblique drainage grooves. Combined with the wider oblique drainage groove and straight drainage groove design at the rear end, it can efficiently guide and quickly drain a large amount of water, avoiding the "semi-floating" phenomenon of the tire in water. The drainage tread blocks on the rear side and the water-cutting tread blocks inside can effectively break the water film tension and ensure the tire tread is in contact with the ground. The asymmetrically arranged hook-shaped tread grooves and grip tread blocks on the front side provide extremely strong lateral grip and drainage performance when the vehicle is cornering, preventing sideslip. It effectively overcomes the shortcomings of existing wet tires that are prone to slipping when turning on rainy or waterlogged roads, and significantly improves driving safety.
[0021] 2. The present invention proposes an anti-slip asymmetrical rain tire structure. By incorporating sound-absorbing cotton, multiple small sound-absorbing cotton pieces are attached to the inner wall of the rain tire. When the tire is punctured, after removing and repairing the puncture site, only the sound-absorbing cotton at the puncture site needs to be reattached. This avoids the problem of relatively high costs associated with the traditional method of removing and replacing the entire sound-absorbing cotton strip. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] One specific embodiment of this utility model is provided:
[0034] Reference Figure 1 , Figure 4 and Figure 6 :
[0035] A wet-slip asymmetric rain tire structure includes a tire body assembly 1, which includes a tread 101. The outer wall of the tread 101 is provided with a tread pattern assembly 2. The tread pattern assembly 2 includes a first annular groove 205 formed in the middle of the outer wall of the tread 101. A second annular groove 206 is formed at both the front and rear ends of the first annular groove 205. Multiple oblique drainage grooves 210 are alternately formed on the inner walls of both the front and rear ends of the first annular groove 205. Multiple rectangular tread blocks 2 formed by the first annular groove 205, the second annular groove 206, and the oblique drainage grooves 210 are provided at the front and rear ends of the middle of the outer wall of the tread 101. 11. The rear outer wall of the second annular groove 206 at the rear end is provided with a plurality of drainage grooves 201. A water-cutting pattern block 204 is fixedly connected to the middle of the bottom surface of the drainage groove 201. The rear end of the tread 101 is provided with a drainage pattern block 202 formed by the cooperation of the second annular groove 206 at the rear end and the plurality of drainage grooves 201. The inner wall of the front end of the second annular groove 206 at the front end is provided with a plurality of hook-shaped pattern grooves 207. The front end of the outer wall of the tread 101 is provided with a grip pattern block 208 formed by the cooperation of the second annular groove 206 at the front end and the plurality of hook-shaped pattern grooves 207. A plurality of sound-absorbing cotton 3 is arranged in an array inside the tire body assembly 1.
[0036] It can effectively overcome the shortcomings of existing wet tires that are prone to slipping when turning in heavy rain or on flooded roads, and significantly improve driving safety.
[0037] Reference Figure 2 , Figure 3 and Figure 5 :
[0038] The inner wall of the tread 101 is sequentially provided with a covering layer 102, a steel belt layer 103, a stress-absorbing rubber strip 104, a carcass ply layer 105, and an airtight layer 106. Multiple sound-absorbing cottons 3 are attached to the inner wall of the airtight layer 106. The sound-absorbing cottons 3 have a trapezoidal design and are made of polyurethane foam. Because of the trapezoidal design of the sound-absorbing cottons 3, if a nail is stuck in the gap between the multiple sound-absorbing cottons 3, the top of the sound-absorbing cotton 3 can be directly moved, thus avoiding the need to remove the sound-absorbing cotton 3. This further reduces noise. To reduce the later repair costs of the tire, the first annular groove 205 is connected to the second annular groove 206 via an inclined drainage groove 210. The lateral diameter of the front inclined drainage groove 210 is smaller than that of the rear inclined drainage groove 210. This allows a large amount of water accumulated inside the first annular groove 205 to enter the rear second annular groove 206. The water is drained from the inner side of the drainage structure, reducing water discharge on the outer side when cornering, thus improving grip. The rear inclined drainage channel 210 and drainage channel 201 are straight through, and the two corners of drainage channel 201 near the second annular channel 206 are rounded. The water inside the inclined drainage channel 210 can flow directly into the drainage channel 201 under the pressure of the vehicle during driving and be discharged. The rounded design also allows the water inside the inclined drainage channel 210 to flow into the drainage channel 201 through the rear second annular channel 206 and be discharged along with it. The rounded design effectively reduces the resistance of water flow and also reduces the impact of air inside during normal driving, thus achieving the purpose of quietness.
[0039] Reference Figure 3 :
[0040] Multiple drainage grooves 203 are formed on the outer wall of the multiple drainage tread blocks 202. The drainage grooves 203 are connected to the rear second annular groove 206. The longitudinal diameter of the drainage grooves 203 is smaller than that of the drainage grooves 201. By connecting the drainage grooves 203 to the rear second annular groove 206, and by using the drainage grooves 203 to cut the water surface in the water-cutting tread blocks 204 when the vehicle is cornering, the drainage grooves 203 can effectively work with the water-cutting tread blocks 204 to cut the water surface in the water accumulation area, allowing the tire to effectively contact the ground. The outer wall of the contact tread block 208 is provided with multiple gripping grooves 209. The gripping grooves 209 are connected to the front second annular groove 206. The longitudinal diameter of the gripping grooves 209 is smaller than the longitudinal diameter of the hook-shaped tread groove 207. By connecting the gripping grooves 209 to the front second annular groove 206, and by making the longitudinal diameter of the gripping grooves 209 smaller than the longitudinal diameter of the hook-shaped tread groove 207, the gripping grooves 209 can improve the overall grip performance of the wet tire while taking into account the drainage effect, thereby avoiding the problem of sideslip when the vehicle is cornering.
[0041] The innovative pattern component (2) and sound-absorbing cotton (3) in this embodiment can be adapted to car tires of different sizes. This embodiment does not innovate the tire body component (1), which is a demonstration of the prior art.
[0042] Working principle: When fixing the tire to the rim, one side of the grip tread block 208 faces the outside of the rim, and one side of the drainage tread block 202 faces the inside of the rim. Meanwhile, refer to... Figure 1 Direction, to make it move forward in a certain direction. Figure 1When the vehicle is driven normally using the waterproof tire during the rainy season, the rectangular tread block 211 in the middle, under the weight of the vehicle, forces water into the first annular groove 205 and the second annular groove 206. As some water enters the first annular groove 205, the continued flow of water causes it to flow into the inclined drainage channels 210 on both sides. Because the diameter of the rear inclined drainage channel 210 is larger than that of the front inclined drainage channel 210, more water enters the rear... Within the second annular groove 206, because the drainage groove 201 and the rear second annular groove 206 are directly connected, accumulated water can flow directly into the drainage groove 201 through the second annular groove 206. Then, it is cut by the water-cutting tread blocks 204 inside the drainage groove 201, dispersing the surface tension of the water and allowing it to drain more quickly. Simultaneously, during normal driving, when the drainage tread blocks 202 initially run over a large area of water, the surface tension of the water will cause the tire to "semi-float" on the water surface. At this time, the vehicle's own... The weight of the tire causes the water-cutting tread blocks 204 inside the drainage groove 201 to contact the surface of the accumulated water. The "sharp" shape of the water-cutting tread blocks 204 cuts off the surface tension of the water, thus displacing the accumulated water and allowing the tire to directly contact the ground. This avoids the phenomenon of the tire not being able to make direct contact with the ground due to the surface tension of the water, which would cause the vehicle to slip. Simultaneously, when the vehicle turns, the change in the vehicle's center of gravity causes most of the vehicle's weight and pressure to be transferred to the outer two tires furthest from the apex of the turn. At this time, the outer side of the tire contacts the ground through multiple grip tread blocks 208, and then the accumulated water is squeezed into the "check mark" shaped hook grooves 207 through the multiple grip tread blocks 208 for drainage. The multiple grip grooves 209 opened on the surface of the grip tread blocks 208 can not only increase the drainage speed of rainwater, but also effectively increase the friction between the grip tread blocks 208 and the ground. At this time, the pressure on the inner side of the tire is relatively light, so the rainwater is squeezed into the drainage grooves 201 through the rectangular tread blocks 211 for drainage.
