Description

Technical Field

[0001] This application relates to the field of tire technology, and in particular to a tire structure. Background Technology

[0002] As a key component in the contact between a vehicle and the ground, tires have different tread patterns to suit different vehicles and usage scenarios.

[0003] In the agricultural sector, tractors need to operate in a variety of complex environments, such as dry fields, paddy fields, muddy roads, and gravel roads, which places high demands on the overall performance of tires. In the existing technology, some tires improve performance by increasing the number of tread blocks or simply changing the shape of the tread, but this has problems such as easy soil accumulation, high fuel consumption, and poor adaptability to complex road conditions.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a tire structure to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is: a tire structure, including a tire body, on which a left tire tread and a right tire tread are formed protruding from the tire tread. The left tire tread and the right tire tread are both composed of a plurality of first tire tread groups in a ring. The first tire tread group is composed of two first tire blocks. The first tire blocks extend axially from the edge of the tire tread to the center of the tire tread. A corner is formed at the center of the first tire block. The corner is an obtuse angle and faces outward in the rotation direction of the tire body. The first tire blocks on the left tire tread and the right tire tread are staggered.

[0007] In some embodiments, a second tire block is formed on the tire surface between two adjacent first tire blocks on both sides, and the two ends of the second tire block extend to the base of the two first tire blocks respectively.

[0008] In some embodiments, the second tire block is arc-shaped, with the center of the arc located on the outer side of the tire tread. The second tire block protrudes from the tire tread by a height of 2-3 mm, and the first tire block protrudes from the tire tread by a height of 25 mm.

[0009] In some embodiments, the periphery of the base of the first tire block is formed with a transition fillet with a radius of 4 mm, and the periphery of the base of the second tire block is formed with a transition fillet with a radius of 2 mm.

[0010] In some embodiments, the first tire block has a cross-section that is wider at the bottom and narrower at the top, with its top being an arc surface parallel to the platform, and one end of the first tire block extends to the tire surface on one side of the axial direction of the tire body.

[0011] In some embodiments, the opening angle of the corner is 160-170 degrees.

[0012] In some embodiments, the distance between two adjacent first tire blocks is 50 mm.

[0013] In some embodiments, a structural groove is formed on the first tire block on one axial side of the tire body, and the structural groove has the same outline as the first tire block on that side, and is triangular.

[0014] The beneficial effects of this application are as follows: The tire structure of this application is specifically designed for tractor tires, featuring a first tire block with a large spacing and a lateral tilt design, combined with a longitudinal second tire block. It can be used in dry fields, paddy fields, muddy roads, and gravel surfaces. When used in dry fields, the tire has good self-cleaning properties, and mud will not stick to the gap between the two first tire blocks. When used in paddy fields, it has the characteristics of strong grip, low slippage, and high maneuverability. In addition, the first tire block is relatively high, with a small contact area with the ground, resulting in relatively low fuel consumption. Attached Figure Description

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0022] In the embodiments of this application, please refer to Figure 1-4 As shown, this tire structure mainly includes: a tire body 1, on which a left tread 2 and a right tread 3 protruding from the tread are formed. The left tread 2 and the right tread 3 are both composed of several first tread groups 4 in a ring. The first tread group 4 is composed of two first tread blocks 401. The first tread blocks 401 extend axially from the edge of the tread to the center of the tread. A corner 5 is formed at the center of the first tread blocks 401. The corner 5 is an obtuse angle and faces outward in the rotation direction of the tire body 1. The first tread blocks 401 on the left tread 2 and the right tread 3 are staggered. In addition, two adjacent first tread blocks 401 on the left tread 2 and the right tread 3 are in contact with each other. One inner end of the first tread block 401 extends to the corner 5 of the other first tread block 401.

[0023] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0024] like Figure 1 As shown, a second tire block 6 is formed on the tire surface between the two adjacent first tire blocks 401. The two ends of the second tire block 6 extend to the base of the two first tire blocks 401 respectively. The setting of the second tire block 6 can further reduce the amount of mud and debris left between the two adjacent first tire blocks 401.

[0025] Furthermore, the second tire block 6 is arc-shaped, with the center of the arc located on the outer side of the tire tread. The height of the second tire block 6 protruding from the tire tread is 2-3 mm, preferably 2.5 mm, and the height of the first tire block 401 protruding from the tire tread is 25 mm.

[0026] Specifically, the first tire block 401 has a transition fillet 8 with a radius of 4mm at its base periphery, and the second tire block 6 has a transition fillet 8 with a radius of 2mm at its base periphery. The transition fillet 8 at the base of the first tire block 401 and the second tire block 6 can reduce stress concentration at the connection between the tire block and the tread, thereby improving the tire's durability and fatigue life, while also reducing the risk of rubber tearing.

[0027] Furthermore, combined with Figure 2 As shown, the first tire block 401 has a cross-section that is wider at the bottom and narrower at the top, and its top is an arc surface parallel to the platform. One end of the first tire block 401 extends to the tire surface on one side of the axial direction of the tire body 1.

[0028] Specifically, the opening angle of the corner 5 is 160-170 degrees. The larger angle of the corner 5 allows the circumferential coverage of a single first tire block 401 to be larger, thereby improving grip. At the same time, the corner 5 design can also disperse the stress concentration when the tire block touches the ground, reduce the risk of tearing caused by repeated deformation at the root of the tire block, and improve the rigidity of the tire block structure, suppressing uneven wear.

[0029] like Figure 3 As shown, the distance between two adjacent first tire blocks 401 is 50mm. The large distance between the two adjacent tire blocks can prevent a large amount of mud from sticking to the middle of the first tire block 401.

[0030] Furthermore, a structural groove 7 is provided on the first tire block 401 on one axial side of the tire body 1. The structural groove 7 has the same outline as the first tire block 401 on that side and is triangular. The opening of the structural groove 7 can not only improve the grip performance of the tire side / edge, but also absorb the impact of the road surface through local deformation and extend the service life of the tire tread.

[0031] like Figure 4 As shown, in another embodiment, there is only a first tire block 401 distributed in a ring on the tire surface, the left tire tread 2 and the right tire tread 3 are alternately arranged on both sides of the tire surface, and the corner 5 is close to the inner end of the first tire block 401. The angle of the corner 5 is 120-150 degrees, preferably 135 degrees.

[0032] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
