Description

Technical Field

[0001] The invention belongs to the technical field of tire patterns, and in particular relates to a pattern structure of an asymmetric UHP tire and processing equipment thereof. Background Art

[0002] With the rapid development of the automobile industry, especially the rise of high-performance automobiles and new energy vehicle markets, the requirements for tire performance have become increasingly stringent. As a high-end tire product, asymmetric ultra-high performance (UHP) tires play a key role in handling, safety, etc., and their pattern structure design is directly related to the overall performance of the tire.

[0003] Although the existing symmetrical tire pattern design can meet the basic driving needs of the vehicle, it gradually exposes many limitations when dealing with high-performance driving scenarios. In terms of grip performance, the symmetrical pattern is difficult to provide sufficient lateral and longitudinal grip for the tire under extreme conditions such as high-speed cornering and emergency braking. In addition, during the driving process of the vehicle, obvious noise will be generated due to the turbulence of air in the pattern grooves and the periodic contact between the pattern blocks and the ground. This not only reduces the driving comfort, but also poses a potential threat to the hearing health of the driver and passengers in a noisy environment for a long time. Especially in the field of new energy vehicles that focus on quietness, tire noise has become an important factor affecting user experience. Summary of the invention

[0004] The object of the present invention is to provide a pattern structure of an asymmetric UHP tire and a processing device thereof to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a pattern structure of an asymmetric UHP tire, comprising:

[0006] A tire, wherein the first longitudinal groove, the second longitudinal groove, the third longitudinal groove, and the fourth longitudinal groove are sequentially spaced from left to right on the tire surface; a first outer shoulder pattern block group is arranged on one side of the first longitudinal groove, and a first transverse pattern groove is arranged on the first outer shoulder pattern block group; a second outer shoulder pattern block group is arranged on one side of the fourth longitudinal groove, and a second transverse pattern groove is arranged on the second outer shoulder pattern block group; a first inner pattern block group is arranged between the first longitudinal groove and the second longitudinal groove; a central pattern block group is arranged between the third longitudinal groove and the second longitudinal groove; and a second inner pattern block group is arranged between the third longitudinal groove and the fourth longitudinal groove.

[0009] Preferably, the central pattern block group is provided with a second transverse pattern steel sheet and a third transverse pattern steel sheet, the second transverse pattern steel sheet is connected to the second longitudinal groove and the third longitudinal groove, and the third transverse pattern steel sheet is connected to the second longitudinal groove but not to the third longitudinal groove.

[0010] Preferably, the second transverse pattern steel sheet and the third transverse pattern steel sheet are arranged at intervals in the longitudinal circumferential direction of the surface of the central pattern block group, and the third transverse pattern steel sheet is flush with the transverse triangular pattern groove in the horizontal direction.

[0013] Preferably, the first transverse groove is not connected to the first longitudinal groove.

[0014] A processing device comprises the above-mentioned asymmetric UHP tire pattern structure.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) A plurality of tread block groups with different functions are designed on the tire surface, namely, a first outer shoulder tread block group, a second outer shoulder tread block group, a first inner tread block group, a central tread block group and a second inner tread block group. During vehicle driving, each tread block group plays a different role under different working conditions. When the vehicle is turning at high speed, the first outer shoulder tread block group and the second outer shoulder tread block group can provide strong lateral grip to reduce the risk of tire skidding. The first transverse grooves and the second transverse grooves on the outer shoulder tread block group increase the friction between the tire and the ground, so that the tire fits the ground better, thereby effectively improving the lateral grip. When driving in a straight line, accelerating or braking, the inner tread block group and the central tread block group mainly provide longitudinal grip, so that the driving force or braking force can be transmitted more efficiently when the vehicle is accelerating or braking, ensuring smooth acceleration and braking of the vehicle.

[0017] (2) Through the connection between the first transverse pattern steel sheet, the second transverse pattern steel sheet, etc. and the longitudinal groove, as well as the design of the transverse triangular pattern groove, etc., the air can flow more smoothly, reducing the turbulence and squeezing of the air, thereby reducing the generation of noise, creating a quieter and more comfortable environment for the driver and passengers, thereby greatly reducing the generation of resonance noise.

[0018] (3) The transverse pattern grooves and steel sheets on each tread block group cooperate with the longitudinal grooves to further improve the drainage performance. The first transverse pattern steel sheet is connected to the first longitudinal groove, which can quickly guide the accumulated water near the first inner tread block group to the longitudinal groove for discharge. The transverse triangular pattern groove is connected to the second longitudinal groove, which can also play an auxiliary drainage role. The transverse pattern steel sheets on the central tread block group and the second inner tread block group can also guide the accumulated water in the corresponding area to the longitudinal groove, accelerating the drainage process and ensuring that the tire always maintains good grip and handling performance on wet roads.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The present invention provides Figure 1 The tread structure of an asymmetric UHP tire shown includes:

[0030] A tire, wherein the surface of the tire is provided with a first longitudinal groove 1, a second longitudinal groove 2, a third longitudinal groove 3, and a fourth longitudinal groove 4 in sequence from left to right, a first outer shoulder block group 101 is provided on one side of the first longitudinal groove 1, and a first transverse groove 1011 is provided on the first outer shoulder block group 101, a second outer shoulder block group 102 is provided on one side of the fourth longitudinal groove 4, and a second transverse groove 1021 is provided on the second outer shoulder block group 102, a first inner block group 103 is provided between the first longitudinal groove 1 and the second longitudinal groove 2, a central block group 104 is provided between the third longitudinal groove 3 and the second longitudinal groove 2, and a second inner block group 105 is provided between the third longitudinal groove 3 and the fourth longitudinal groove 4.

[0031] The first inner pattern block group 103 is provided with a first transverse pattern steel sheet 1031 and a transverse triangular pattern groove 1032 . The first transverse pattern steel sheet 1031 is connected to the first longitudinal groove 1 , and the first transverse pattern steel sheet 1031 is not connected to the second longitudinal groove 2 .

[0032] The transverse triangular pattern groove 1032 is connected to the second longitudinal groove 2 , the first transverse pattern steel sheet 1031 and the transverse triangular pattern groove 1032 are longitudinally spaced apart on the surface of the first inner pattern block group 103 , and the first transverse pattern steel sheet 1031 is arranged on the extension line of the first transverse pattern groove 1011 .

[0033] The central pattern block group 104 is provided with a second transverse pattern steel sheet 1041 and a third transverse pattern steel sheet 1042. The second transverse pattern steel sheet 1041 is connected to the second longitudinal groove 2 and the third longitudinal groove 3. The third transverse pattern steel sheet 1042 is connected to the second longitudinal groove 2 but not to the third longitudinal groove 3. The design of the third transverse pattern steel sheet 1042 being connected to the second longitudinal groove 2 but not to the third longitudinal groove 3 further enriches the drainage route. It can guide the accumulated water in the specific area of ​​the second longitudinal groove 2 to the steel sheet to avoid the local accumulation of accumulated water.

[0034] The second transverse pattern steel sheet 1041 and the third transverse pattern steel sheet 1042 are arranged at intervals in the longitudinal circumferential direction of the surface of the central pattern block group 104, which can expand the contact area between the central pattern block group 104 and the ground. During the acceleration and braking of the vehicle, the longitudinal force can be transmitted more effectively, and the longitudinal grip between the tire and the ground is enhanced. The third transverse pattern steel sheet 1042 is flush with the transverse triangular pattern groove 1032 in the horizontal direction. The flush design allows the central pattern block group 104 and the first inner pattern block group 103 to work together under the action of lateral force, further optimizing the lateral grip performance of the tire and enhancing the stability of the vehicle when driving on curves.

[0035] A fourth transverse pattern steel sheet 1051 is arranged on the second inner pattern block group 105, and the fourth transverse pattern steel sheet 1051 connects the fourth longitudinal groove 4 and the third longitudinal groove 3. The fourth transverse pattern steel sheet 1051 connects the fourth longitudinal groove 4 and the third longitudinal groove 3, so that the two longitudinal grooves are interconnected, forming a more efficient drainage path on the tire surface, and the fourth transverse pattern steel sheet 1051 is arranged on the extension line of the second transverse pattern steel sheet 1041, which means that the drainage path is reasonably connected between different pattern block groups, so that the whole drainage process is coherent and orderly, which greatly improves the overall drainage efficiency of the tire.

[0036] The second transverse pattern groove 1021 is not connected to the fourth longitudinal groove 4, so that when the second outer shoulder pattern block group 102 contacts the ground, the integrity of the pattern block is maintained, and the lateral force can be transmitted more effectively. The second transverse pattern groove 1021 is arranged on the extension line of the fourth transverse pattern steel sheet 1051. When the fourth transverse pattern steel sheet 1051 transmits the longitudinal force, the pattern block where the second transverse pattern groove 1021 is located can take over in time to provide additional lateral grip, so that the tire can maintain good grip performance under complex road conditions.

[0037] The first transverse pattern groove 1011 is not connected to the first longitudinal groove 1. The non-connected design makes the pattern blocks on the first outer shoulder pattern block group 101 more complete. When the vehicle turns, the outer side of the tire is subjected to a larger lateral force. At this time, the pattern blocks on both sides of the first transverse pattern groove 1011 can be in close contact with the ground, providing stronger lateral friction and enhancing the lateral grip of the tire.

[0038] A processing device comprises the above-mentioned asymmetric UHP tire pattern structure.

[0039] The pattern structure of the asymmetric UHP tire and the processing equipment thereof, when the vehicle is traveling in a straight line, the plurality of inner pattern block groups and the central pattern block group 104 mainly provide gripping force, the first transverse pattern steel sheet 1031 on the first inner pattern block group 103 is connected with the first longitudinal groove 1, when the vehicle is accelerating, the driving force generated by the engine is transmitted to the ground through the tire, the first transverse pattern steel sheet 1031 and the first longitudinal groove 1 connected thereto can more effectively disperse the driving force to the ground, so that the tire can better bite the ground and achieve smooth acceleration, when braking, the braking force of the ground is transmitted to the tire through the first transverse pattern steel sheet 1031 and the first longitudinal groove 1, helping the vehicle to brake quickly;

[0040] When the vehicle turns, the outer shoulder pattern block group is subjected to a large lateral force. Taking turning right as an example, the first outer shoulder pattern block group 101 is subjected to the lateral force generated by the centrifugal force of the vehicle. At this time, the first transverse pattern groove 1011 on the first outer shoulder pattern block group 101 contacts the ground, increasing the friction between the tire and the ground. At the same time, the structure of the pattern block itself can better resist the lateral force, provide strong lateral grip for the tire, prevent the tire from skidding, and ensure smooth turning of the vehicle.

[0041] During the rolling process of the tire, due to the regularity of the traditional symmetrical pattern, the vibration frequencies generated by each pattern block and groove are similar, which easily causes resonance and generates relatively large noise. However, the asymmetrical pattern design of the present invention makes the transverse pattern grooves and steel sheets on different pattern block groups arranged at intervals in the longitudinal circumferential direction, and have different shapes and sizes. In this way, when the tire rolls, the vibration frequencies generated by each pattern block and groove are different, which interfere with each other and cannot form resonance, thereby reducing the generation of noise;

[0042] Moreover, air flows in various pattern grooves and pattern steel sheets. If the air flow is not smooth, turbulence will be generated, thereby generating noise. In the present invention, the connection method between the first transverse pattern steel sheet 1031, the second transverse pattern steel sheet 1041, etc. and the multiple longitudinal grooves, as well as the design of the transverse triangular pattern grooves 1032, etc., provide a smoother path for air flow. When the air flows in these pattern structures, turbulence and extrusion are reduced, thereby reducing the generation of noise.

[0043] When driving on rainy days or flooded roads, the tire comes into contact with a large amount of accumulated water. The first longitudinal groove 1, the second longitudinal groove 2, the third longitudinal groove 3, and the fourth longitudinal groove 4 serve as main drainage channels. By utilizing their inclination angles and the rolling of the tire, the accumulated water is quickly discharged from the tire surface. When the tire rolls, the accumulated water flows from one side of the tire to the other side along the multiple longitudinal grooves under the action of gravity and the centrifugal force generated by the rolling of the tire, effectively reducing the thickness of the water film between the tire and the ground, and reducing the probability of the "hydroplaning" phenomenon.

[0044] The transverse pattern grooves and pattern steel sheets on each pattern block group cooperate with the longitudinal grooves to assist drainage. The first transverse pattern steel sheet 1031 is connected with the first longitudinal groove 1, and can quickly guide the accumulated water near the first inner pattern block group 103 to the first longitudinal groove 1, and then discharge it through the first longitudinal groove 1. The transverse triangular pattern groove 1032 is connected with the second longitudinal groove 2, and can guide the accumulated water in the corresponding area into the second longitudinal groove 2. The second transverse pattern steel sheet 1041 and the fourth transverse pattern steel sheet 1051 on the central pattern block group 104 and the second inner pattern block group 105 can also guide the accumulated water in their respective areas to the corresponding longitudinal grooves, thereby accelerating the drainage process and ensuring that the tire's grip and handling performance on wet roads are not affected.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
