An agricultural tire structure

Abstract

This utility model relates to an agricultural tire structure, comprising: two sets of tread grooves, symmetrically distributed along the tire tread centerline, with multiple grooves in each set, evenly distributed along the tire circumference. The end of each groove near the tire sidewall is open and has a transition arc. The grooves slope from the sidewall towards the tread center, forming interconnected U-shaped tread blocks, with the bottom of the U-shaped blocks located at the tire sidewall. By setting two sets of symmetrically distributed tread grooves and forming U-shaped tread blocks between them, the tire exhibits stronger grip and traction in complex terrain. Furthermore, the sloping grooves from the sidewall towards the tread center and the transition arc not only improve water and mud drainage but also effectively reduce stress concentration, thereby enhancing the tire's wear resistance and service life.

Description

Technical Field

[0001] This utility model relates to the field of tire technology, specifically to an agricultural tire structure. Background Technology

[0002] In the widespread application of modern agricultural machinery, agricultural tires are one of the key components, and their performance directly affects the working efficiency and operating costs of the equipment.

[0003] However, existing agricultural tires still have many shortcomings in practical applications. Traditional tires generally have shallow tread designs, resulting in limited grip and a tendency to slip on wet, muddy, or soft surfaces, affecting the passability and handling stability of machinery. Furthermore, existing tread structures perform poorly in complex terrain, especially steep slopes, limiting climbing ability and failing to meet the needs of agricultural operations in mountainous and hilly areas. In addition, due to the harsh conditions of agricultural operations, tires are in constant contact with rough surfaces such as soil and rocks, leading to insufficient wear resistance and a relatively short lifespan for traditional tires, increasing maintenance and replacement frequency and raising operating costs. Under high-speed or heavy-load conditions, the inadequate tread design of some tires results in uneven ground pressure distribution, further affecting operational stability and handling safety. Therefore, this paper proposes an agricultural tire structure to address these problems. Utility Model Content

[0004] This utility model provides an agricultural tire structure. The large herringbone pattern formed by the tread grooves can effectively disperse the pressure when the tire contacts the ground, reducing wear. At the same time, it enables agricultural machinery to maintain a stable driving state when climbing slopes or in complex road conditions such as mud and gravel, reducing the risk of slippage.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An agricultural tire structure, comprising:

[0006] There are two sets of tread grooves, which are symmetrically distributed along the center line of the tire tread. Each set has multiple tread grooves, which are evenly distributed on the tire tread circumferentially. The end of the tread groove near the tire sidewall is open and has a transition arc. The tread groove is inclined from the tire sidewall toward the center of the tread. The tread grooves form connected U-shaped tread blocks, and the bottom of the U-shaped tread blocks is located at the tire sidewall.

[0007] The number of shoulder protrusions is the same as the number of tread grooves, and they are located at the openings of the tread grooves.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the other end of the tread groove, away from the opening end, crosses the centerline of the tire tread.

[0010] Furthermore, the depth of the patterned groove is 33.5 mm, the bottom of the groove is provided with a large rounded corner of 47 mm, and the inclination is a radial angle of 11°~15°.

[0011] Furthermore, the shoulder protrusion is trapezoidal in shape with the narrow end facing inward and the wide end facing outward, and its height is 60% to 80% of the height of the U-shaped tread block.

[0012] Furthermore, each of the two inner sides of the patterned groove is provided with a support portion that connects to its bottom.

[0013] Furthermore, two support portions are provided on each of the two inner sides of the patterned horizontal groove, and the support portions on both sides are staggered.

[0014] Furthermore, it also includes two sidewall and shoulder reinforcement sections, one on each side of the tire.

[0015] Furthermore, the tire sidewall and shoulder reinforcement includes an annular reinforcement provided on the tire sidewall. The annular reinforcement is provided with an outwardly extending tread block shoulder and a raised shoulder shoulder that respectively overlap the outside of the U-shaped tread block and the raised shoulder. The corners of the tread block shoulder and the raised shoulder shoulder are rounded.

[0016] Furthermore, the annular reinforcement section is provided with multiple rings of steel wire from the inside to the outside, and the patterned block shoulder and the raised shoulder are both provided with a steel wire mesh woven from multiple transverse steel wires and multiple longitudinal steel wires, wherein the longitudinal steel wires extend into the annular reinforcement section and are woven together with the multiple rings of steel wire.

[0017] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0018] 1. This agricultural tire structure features two sets of staggered and symmetrically distributed tread grooves, forming U-shaped tread blocks between them. This design enhances the tire's grip and traction in complex terrain. Furthermore, the tread grooves slope from the sidewall towards the center of the tread and incorporate a transition arc, improving water and mud drainage while effectively reducing stress concentration and increasing wear resistance and lifespan. Additionally, the shoulder protrusions located at the openings of the tread grooves enhance support and edge grip in the shoulder area, making the tire more stable and reliable when operating on wet or soft surfaces.

[0019] 2. This agricultural tire structure enhances the structural strength of the tread blocks by setting staggered support sections inside the tread grooves, preventing them from breaking or deforming during long-term use. The sidewall and shoulder reinforcement sections, through a composite reinforcement structure consisting of annular reinforcement sections, tread block guards, and raised guards, as well as the synergistic effect of the internally embedded steel wire mesh and multi-ring steel wire rings, significantly improve the overall rigidity, impact resistance, and durability of the tire.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] like Figure 1-3As shown, an agricultural tire structure in this embodiment includes tread grooves 1 and shoulder protrusions 3. The tread grooves 1 are in two sets, symmetrically distributed along the tire tread centerline, with the end of each groove extending beyond the centerline of the tire tread, forming a herringbone pattern. This increases the coverage area of ​​the tread grooves 1 on the tire tread, improving the tire's adaptability and grip under various working conditions. Each set contains multiple tread grooves 1, evenly distributed along the tire circumference on the tire tread. The end of each tread groove 1 near the tire sidewall is open and has a transition arc to reduce stress concentration and improve structural strength and wear resistance. The lateral grooves 1 are inclined from the sidewall towards the center of the tread. The depth of the lateral grooves 1 is 33.5mm, and the bottom of the groove has a large rounded corner of 47mm. The radial inclination angle is 11°~15°, which can better achieve heat dissipation and enhance the tire's grip and driving stability. The large rounded corner design at the bottom of the groove can not only prevent tread chipping and blockage, alleviate stress concentration at the bottom of the groove, improve the crack resistance of the groove area, prevent early cracking and damage, and improve the overall rigidity and wear resistance of the tread blocks, but also automatically remove stones embedded in the bottom of the groove, improve the tire's self-cleaning performance, facilitate maintenance, and extend the service life due to the greater tread depth.

[0031] In addition, this design forms connected U-shaped tread blocks 2 between the tread grooves 1, and the bottom of the U-shaped tread blocks 2 is located at the tire sidewall, which makes the driving surface stable and has strong friction resistance. The connecting surface adopts a gradual arc transition. This shape not only improves the heat dissipation performance of the tire surface, but also makes it easy to drain water and mud, reduce hydroplaning, and make driving worry-free in rainy weather.

[0032] The number of shoulder protrusions 3 is the same as the number of tread grooves 1, and they are located at the opening of the tread grooves 1. In this embodiment, the shoulder protrusions 3 are trapezoidal in shape with the narrow end facing inward and the wide end facing outward, and their height is 60% to 80% of the height of the U-shaped tread block 2. The shoulder protrusions not only enhance the wear resistance and grip performance of the shoulder area, but also provide additional support when the tire is turning or driving on a slope.

[0033] Furthermore, each of the two inner sides of the patterned groove 1 is provided with a support part 4 connected to its bottom, which can enhance the structural strength of the patterned block and distribute the force.

[0034] In a preferred embodiment, two support portions 4 are provided on each of the two inner sides of the patterned horizontal groove 1, and the support portions 4 on both sides are staggered.

[0035] This design creates a more reasonable stress-bearing structure, preventing the patterned blocks from breaking or deforming during long-term use.

[0036] Example 2

[0037] In conjunction with the solution described in Embodiment 1, such as Figure 1-6 As shown, in order to improve the overall structural strength and durability of the tire, this embodiment also includes two sidewall and shoulder reinforcement parts 5, which are respectively provided on both sides of the tire.

[0038] Furthermore, the tire sidewall and shoulder reinforcement 5 includes an annular reinforcement 501 disposed on the tire sidewall. The annular reinforcement 501 is provided with outwardly extending tread block shoulders 502 and shoulder shoulders 503 that overlap the U-shaped tread block 2 and the shoulder protrusion 3 respectively, which serve to strengthen and protect. The corners of the tread block shoulders 502 and the shoulder shoulders 503 are rounded to avoid stress concentration and increased wear.

[0039] Furthermore, the annular reinforcement 501 is provided with multiple rings of steel wire 504 arranged sequentially from the inside to the outside. The tread block shoulder 502 and the raised shoulder 503 are both provided with a steel wire mesh woven from multiple transverse steel wires 505 and multiple longitudinal steel wires 506. The longitudinal steel wires 506 extend into the annular reinforcement 501 and are woven together with the multiple rings of steel wire 504 to form an integral high-strength reinforcement system, which significantly improves the rigidity, wear resistance and impact resistance of the tire sidewall and shoulder.

[0040] In summary, through the above structural design, the agricultural tire structure provided by this utility model not only ensures good grip performance, but also has excellent wear resistance, structural stability and long service life. It is particularly suitable for complex operating environments such as hills, mountains and mud, and can effectively improve the passability, maneuverability and operating efficiency of agricultural machinery. It has good application prospects and promotion value.

[0041] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
