Description
Technical Field
[0001] The utility model belongs to the technical field of guiding tires, and more particularly, relates to a pattern tire for a load-carrying medium and long-distance guiding wheel. Background Art
[0002] Automobile tires are an indispensable part of the modern transportation system. They not only bear the weight of the vehicle but also directly affect the safety, handling performance, comfort, and fuel economy of the vehicle. With the development of the automotive industry and the continuous improvement of people's requirements for travel quality, tire technology has been continuously progressing and innovating. Currently, the tires sold on the market mainly focus on basic performance, such as the load capacity and size specifications of the tires, to meet the basic needs of daily vehicle driving. However, with the continuous growth of the number of automobiles and the continuous improvement of the highway network, the requirements for tire performance are gradually increasing. Especially under high-speed driving conditions, the handling stability, ground adhesion, driving safety, fuel-saving performance, and wear resistance of the tires have become the focus of attention for users and manufacturers.
[0003] The design of tire patterns is crucial for the overall performance of tires. Patterns can not only affect the appearance of tires but, more importantly, have a direct impact on the performance of tires. Different pattern designs can significantly improve the performance of tires under various road conditions. For example, asymmetric pattern designs can improve the handling stability and grip of tires; multi-directional pattern designs can improve the drainage performance of tires and reduce hydroplaning; closed pattern designs can improve the lateral support force of tires and enhance the handling performance. In addition, pattern design can also affect the noise level and heat dissipation performance of tires, thereby affecting the comfort experience of drivers and the service life of tires. With the increasing requirements for tire performance, how to use knife grooves to improve the wear resistance, heat dissipation performance, and reduce the noise of tires has become an important research direction in tire pattern design. By improving the pattern design, the wear resistance of tires can be effectively improved. At the same time, through some pattern designs for stone removal, the overall stone-removing performance of tires can be improved, and the risk of tire chunking and damage to the bottom of the pattern grooves can be reduced, thereby extending the service life of tires. Summary of the Utility Model
[0004] In view of this, the utility model provides a pattern tire for a load-carrying medium and long-distance guiding wheel, which solves the drawback that a large amount of heat will be generated during the use of the patterns of traditional guiding tires, and the high temperature will affect the wear resistance of the rubber compound, and improves the wear resistance of the tires.
[0005] The utility model is implemented as follows:
[0006] The utility model provides a pattern tire for a load-carrying medium- and long-distance steering wheel, including a tread pattern, wherein: the tread pattern includes a first central pattern block, two second intermediate pattern blocks, and two third shoulder pattern blocks. The two second intermediate pattern blocks are respectively located on the left and right sides of the first central pattern block. A first intermediate pattern groove is provided between the first central pattern block and the second intermediate pattern block. One end of the second intermediate pattern block is close to the first central pattern block, and the other end is close to the third shoulder pattern block. The other end of the third shoulder pattern block is a free end. A second shoulder zigzag pattern groove is provided between the second intermediate pattern block and the third shoulder pattern block. A first knife groove is provided on the first central pattern block. The second intermediate pattern block is provided with a second knife groove and a third knife groove. The second knife groove is used to increase wet grip. A buffer pressure steel sheet and a fourth knife groove are provided at the edge of the third shoulder pattern block. The fourth knife groove is used to increase wet grip.
[0007] The technical effects of a pattern tire for a load-carrying medium- and long-distance steering wheel provided by the utility model are as follows: including a tread pattern, the tread pattern includes a central pattern block, an intermediate pattern block, a shoulder pattern block, as well as an intermediate pattern groove and a shoulder pattern groove. The central pattern block has a knife groove with a bionic shape. The intermediate pattern block has different pattern knife grooves for providing wet grip. The edge of the shoulder pattern groove has a knife groove for buffering the tread pressure. At the same time, the shoulder pattern block also has a pattern knife groove for providing wet grip. The bottom of the intermediate pattern groove has a stone-bouncing boss. The bottom of the shoulder pattern groove adopts a zigzag asymmetric angle design, having good self-cleaning performance.
[0008] On the basis of the above technical solution, a pattern tire for a load-carrying medium- and long-distance steering wheel of the utility model can also be improved as follows:
[0009] Wherein, the first knife groove is specifically a bionic shape knife groove, and the depth of the first knife groove is less than 4 mm.
[0010] Bionics: is a discipline that imitates the structure, function, and principle of organisms in nature to solve engineering technical problems.
[0011] Bionic shape: refers to imitating the biological form and structural characteristics in nature in product design to create a design that is both beautiful and highly functional.
[0012] "Bionic shape knife groove" means designing the groove on the tool by imitating the biological characteristics in nature in tool design.
[0013] Furthermore, the depth of the second knife groove gradually becomes deeper from the midpoint to both sides. The midpoint of the second knife groove is a shallow knife groove, and the two side positions are deep knife grooves. The depth of the shallow knife groove is less than 4 mm, and the depth of the deep knife groove is greater than 4 mm and less than 16 mm.
[0014] Furthermore, the depth of the third cutter groove is less than 4 mm.
[0015] Furthermore, the depth of the fourth cutter groove is less than 4 mm.
[0016] Furthermore, the depth of the buffer pressure steel sheet is greater than 4 mm and less than 16 mm.
[0017] Furthermore, the first intermediate tread groove is provided with a stone-elastic convex platform, and the height of the stone-elastic convex platform is greater than 2 mm and less than 6 mm.
[0018] Furthermore, the second shoulder zigzag tread groove adopts a variable-angle zigzag design, which is divided into angle A and angle B by a demarcation line. The angles of the second shoulder zigzag tread groove are asymmetric, and the asymmetric angles A and B are less than or equal to 20 degrees.
[0019] The variable-angle zigzag design means that the tread grooves in the tire shoulder area are not arranged at a fixed and consistent angle, but are arranged at different angles according to different positions. The purpose of this design is to improve the performance of the tire under different driving conditions, such as grip, drainage capacity, and noise level.
[0020] Angle asymmetry means that the tire tread grooves adopt one angle design on one half of the tire and a different angle design on the other half. This asymmetric design can make the tire exhibit different characteristics in different directions. For example, one side may be more suitable for straight-line driving, while the other side is more conducive to the grip during turning.
[0021] Furthermore, the tire adopts an equal pitch tread design.
[0022] The beneficial effects of adopting the above improvement scheme are as follows: The closed shoulder design means that the area between the tire sidewall and the ground contact part (tread) is designed as a relatively closed or continuous structure, rather than having open grooves or cuts like traditional tires. The main purpose of this design is to improve the rigidity of the tire sidewall and reduce the deformation of the tire during turning, thereby improving the vehicle's handling performance and stability. The closed shoulder can also help reduce noise because it reduces the turbulence generated when air passes through the shoulder grooves.
[0023] Furthermore, the tire adopts a closed shoulder design.
[0024] The beneficial effects of adopting the above improvement scheme are as follows: The equal pitch pattern design means that there are equal distances or intervals between the tread blocks on the tire. This design is usually used to improve the uniformity of the tire and reduce the noise during rolling. Since the contact time of each tread block with the ground is more uniform, it helps to reduce the vibration and noise caused by irregular patterns. In addition, the equal pitch pattern design also helps to improve the drainage performance of the tire, reduce the hydroplaning phenomenon, and improve the grip on wet roads.
[0025] Compared with the prior art, the beneficial effects of a heavy-duty medium and long-distance steering wheel pattern tire provided by the present utility model are:
[0026] The bionic knife groove design on the first central tread block improves the aesthetic performance of the tire and increases wear resistance on this basis;
[0027] The variable-depth knife grooves are designed on the second intermediate tread block, which helps to dissipate heat and ensures that the tire still has good wet grip performance in the later stage of wear;
[0028] The four tread grooves have excellent drainage and heat dissipation performance, which can improve the controllability of the tire;
[0029] The closed shoulder design of the third shoulder tread block can better improve the controllability of the tire, prevent uneven wear, improve the driving stability, and improve the comfort performance;
[0030] The edge steel sheet design of the third shoulder tread block can reduce the heat generated during the use of the tire, prevent the early damage of the tire, and at the same time can buffer the edge pressure of the shoulder tread block, prevent uneven wear, and increase the wear mileage of the tire;
[0031] The design of the stone ejecting convex platform in the middle tread groove can improve the stone ejecting performance of the tire, ensure good wear resistance of the tire, and reduce the risk of tire chunking and damage to the bottom of the tread groove;
[0032] The asymmetric angle design of the second shoulder zigzag tread groove improves the lateral controllability and at the same time can improve the stone ejecting performance of the tire. Description of the Drawings

[0064] Closed Shoulder Design Principle: Closed shoulder design means that the tire shoulder area adopts a continuous and closed tread design to enhance the rigidity of the shoulder. This design can improve the handling performance of the tire during turning, reduce uneven wear, and improve driving stability;
[0065] Edge Steel Sheet Design Principle: Edge steel sheet design means adding small protrusions made of hard materials to the edges of the tread blocks on the tire shoulder to enhance the edge strength of the tread blocks. This design can reduce heat generation during tire use and improve tire durability;
[0066] There is a Stone Ejecting Boss Design in the Middle Tread Groove:
