Description

Technical Field

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

[0002] In agricultural production, tires are one of the key components of agricultural machinery. Radial tires, in particular, are a new type of tire with cords arranged along the meridian, and a buffer layer with cords arranged circumferentially or nearly circumferentially tightly bound to the tire body. They are characterized by a large contact patch and sufficient driving force. With the development of agricultural modernization, the performance requirements for tires are increasingly higher. Good tire performance can not only improve the operating efficiency of agricultural machinery but also reduce maintenance costs, avoid the expenses of frequent tire replacements, and extend the service life of equipment.

[0003] Currently, in the traditional design of radial tire patterns for agricultural vehicles, in order to ensure the service life of the tread pattern, the entire tread is often thickened to increase its strength; the overall durability of the tread pattern is also improved by improving the vulcanization process, etc., to resist wear and damage during daily use.

[0004] However, during agricultural machinery operation, especially in complex farmland environments, tire treads need to withstand significant pressure and friction. When encountering stones, hard objects, or uneven ground, the tread patterns are easily damaged, particularly at the base of the tread where insufficient strength can lead to cracks. Once tread root cracks occur, it significantly shortens the tire's lifespan, reduces its grip and stability, increases the operational risks of agricultural machinery, and hinders the normal conduct of agricultural operations.

[0005] The aforementioned technologies have the defect of poor tread pattern durability. Utility Model Content

[0006] To improve the problem of poor tread pattern durability, this application provides a tread pattern structure for agricultural radial tires.

[0007] The agricultural radial tire tread pattern structure provided in this application adopts the following technical solution:

[0008] An agricultural radial tire tread structure includes a tread pattern comprising: tread blocks, wherein a plurality of tread blocks are provided on the tire surface, the center line of the tire surface extends circumferentially, the plurality of tread blocks are evenly and alternately distributed on both sides of the center line of the tire surface, and a tread groove is formed between two adjacent tread blocks along the direction of extension of the center line of the tire surface, the height of the tread groove being lower than the height of the tread block, so that the tread block protrudes from the tread groove on the tire surface; and reinforcing ribs, wherein a plurality of reinforcing ribs are provided, the reinforcing ribs being correspondingly provided with the tread blocks, and the reinforcing ribs being provided at the connection between the tread blocks and the tread grooves.

[0009] By adopting the above technical solution, several tread blocks are evenly and alternately distributed on both sides of the center line of the tread. There are tread grooves between adjacent tread blocks, which are lower than the tread blocks, so that the tread blocks protrude on the tread. During the driving of agricultural radial tires, this distribution method can make the contact between the tire and the ground more uniform, which helps to enhance the tire's grip and reduce tread root cracks caused by stress concentration. The reinforcing ribs are set at the connection between the tread blocks and the tread grooves, which can enhance the rigidity of the tread pattern, prevent tread root cracks, and extend the tire's service life.

[0010] Optionally, the patterned groove is provided with a step, and the two ends of the step are respectively connected to two adjacent patterned blocks.

[0011] By adopting the above technical solution, steps are set at the bottom of the tread groove and two adjacent tread blocks are connected at each end. The steps can form a tortuous structure at the bottom of the tread groove. When the tire is driving on muddy or other complex road conditions, this tortuous structure can change the flow path and direction of impurities such as mud and water, prevent the accumulation of impurities in the tread groove, and effectively improve the sewage discharge and self-cleaning function.

[0012] Optionally, the step includes a first part, a second part, and a bent part. The first end of the first part and the first end of the second part are respectively connected to two patterned blocks. The two ends of the bent part are respectively connected to the second end of the first part and the second end of the second part. The extension directions of the first part and the second part are both set at an angle to the extension direction of the bent part. The bent part causes the first part and the second part to be misaligned.

[0013] By adopting the above technical solution, the first end of the first part and the first part of the step are respectively connected to two pattern blocks, which can stably connect adjacent pattern blocks and ensure the integrity of the tread pattern structure; the two ends of the bend are respectively connected to the second ends of the first part and the second part, and the extension direction of the first part and the second part is set at an angle with the extension direction of the bend and the two are misaligned. This tortuous step design can effectively improve the sewage discharge and self-cleaning function of the agricultural radial tire pattern.

[0014] Optionally, the same patterned groove may have at least one step.

[0015] By adopting the above technical solution, the tread groove is provided with at least one step. This tortuous step design can change the flow path and state of mud, water and other dirt during tire rolling, making it easier to be discharged from the tire, thereby effectively improving the dirt discharge and self-cleaning function of the agricultural radial tire tread structure.

[0016] Optionally, the grooved surface is provided with a self-cleaning block.

[0017] By adopting the above technical solution, a self-cleaning block is set at the bottom of the tread groove. When the agricultural radial tire is working in the field, the self-cleaning block can automatically pop out the mud or gravel stuck in the tread groove, realize the sewage discharge and self-cleaning function, and also prevent mud from sticking to the tread groove, ensuring the normal use of the tire and its grip performance.

[0018] Optionally, the self-cleaning block is located at one end of the tread groove away from the centerline of the tire tread.

[0019] By adopting the above technical solution, the self-cleaning block is placed at the bottom of the tread groove at one end away from the center line of the tire tread. When operating in the field with a radial tire, it can more effectively and automatically eject mud or gravel that has entered the tread groove, thus better achieving the self-cleaning and anti-mud-sticking functions.

[0020] Optionally, the self-cleaning block includes a first group and a second group. The first group is inclined and arranged along the forward direction of the agricultural radial tire. The first end of the first group near the center line of the tire tread is located in front of the second end of the first group away from the center line of the tire tread. The first group and the second group are spaced apart.

[0021] By adopting the above technical solution, the self-cleaning blocks are divided into a first group and a second group, with the first group positioned at an angle. The end of the first group closest to the tire's centerline is positioned in front of the end furthest from the centerline in the forward direction. This arrangement better utilizes the tire's forward momentum, making it easier to remove mud or gravel from the tread grooves when the tire encounters them in the field, thus achieving the self-cleaning function. Furthermore, the alternating arrangement of the first and second groups ensures a rational structural layout for the entire self-cleaning block, expanding its effective range and further improving its self-cleaning efficiency and anti-mud adhesion effect.

[0022] Optionally, both the first group and the second group include a plurality of bumps, the bumps being arranged along the extending direction of the first group, and the number of bumps in the first group and the second group being the same or different.

[0023] By adopting the above technical solution, the first and second groups are inclined and spaced apart along the forward direction of the agricultural radial tire. Each group contains several protrusions arranged along its own extension direction. This structure allows the self-cleaning blocks to better contact with mud or gravel during the rolling of the agricultural radial tire. The inclined angle facilitates the automatic ejection of mud or gravel stuck in the tread grooves, achieving self-cleaning and anti-mud-sticking effects. Furthermore, the number of protrusions in the first and second groups can be the same or different, allowing for flexible adjustment of the self-cleaning block layout according to actual needs to adapt to different operating environments and usage scenarios, further optimizing the self-cleaning and anti-mud-sticking effects.

[0024] Optionally, the tread block includes a head and a body. The head is connected to a first end of the body near the center line of the tread. The second end of the body extends away from the center line of the tread and along the forward direction of the agricultural radial tire. The head is located in front of the second end of the body and along the width direction perpendicular to the extension direction of the tread block. The maximum width of the head is greater than the maximum width of the body.

[0025] By adopting the above technical solution, the head of the tread block is connected to one end of the main body near the center line of the tread, and the other end of the main body extends away from the center line of the tread. The head is located in front of the main body in the forward direction of the agricultural radial tire, and the maximum width of the head is greater than the maximum width of the main body. This enlarged head can effectively enhance the tire's grip and improve wear resistance. In addition, the head being located in front of the main body can contact the ground first and bear a certain force. Combined with the larger head width, it is beneficial to distribute the force and further improve grip and wear resistance.

[0026] Optionally, the two sides of the connection between the head and the main body are transitioned by curved surfaces.

[0027] By adopting the above technical solution, the two sides of the connection between the head and the main body of the tread block are curved, which makes the lines of the tread pattern smoother, effectively reduces stress concentration, and further improves the anti-skid performance. At the same time, this smooth transition helps to enhance the efficiency of force transmission during tire driving, improves grip, and also improves the overall rigidity of the tread pattern, avoiding tread root cracking caused by uneven stress.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The enlarged head design of the patterned blocks enhances grip and wear resistance, while the curved transition with the main body improves anti-slip performance;

[0030] 2. Reinforcing ribs are placed at the connection between the tread blocks and the tread grooves to enhance the strength of the tread pattern and prevent cracking at the tread root;

[0031] 3. The bottom of the patterned ditch adopts a zigzag step design and a self-cleaning block design, which can improve the sewage discharge and self-cleaning function. When working in the field, it can automatically pop out mud or gravel, and has the functions of self-cleaning and anti-mud sticking. Attached Figure Description

[0042] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be further described in detail below. In this embodiment, unless otherwise specified, "connection", "linking", and "fixing" are interpreted broadly, including fixed connection, detachable connection, connection to form an integral structure, mechanical connection, electrical connection, direct connection, indirect connection through an intermediary, internal connection, and interaction between two components, etc., and can be understood according to the specific circumstances.

[0043] In this application, unless otherwise expressly specified and limited, "above" or "below" a second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, in the description of this embodiment, terms such as "above," "below," "left," and "right," etc., are based on the orientation or positional relationships shown in the accompanying drawings and are used only for ease of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Unless otherwise stated, directional terms such as "inner" and "outer" used in this application refer to the outline of the corresponding component itself.

[0044] like Figure 1 As shown in the embodiment of this application, an agricultural radial tire tread structure (hereinafter referred to as "tread structure") is disclosed. The tread structure includes a tread pattern, which includes tread blocks 1 and reinforcing ribs 3 evenly disposed on the tire surface.

[0045] like Figure 2 As shown, the tread block 1 is generally strip-shaped, and there are several tread blocks 1. The centerline of the tread extends circumferentially, and the several tread blocks 1 are evenly and alternately distributed on both sides of the centerline of the tread. During the driving of agricultural radial tires, this distribution pattern can make the contact between the tire and the ground more uniform, ensuring sufficient contact area, which helps to enhance the tire's grip, while reducing tread root cracks caused by stress concentration. Along the extension direction of the centerline of the tread, a tread groove 2 is formed between two adjacent tread blocks 1. The height of the tread groove 2 is lower than the height of the tread block 1, so that the tread block 1 protrudes from the tread groove 2 on the tire surface, which can increase the friction between the tire and the ground when the vehicle is turning, and improve the anti-skid performance.

[0046] like Figure 3 As shown, several reinforcing ribs 3 are provided, and the reinforcing ribs 3 are correspondingly arranged with respect to the tread blocks 1. The reinforcing ribs 3 are located at the connection between the tread blocks 1 and the tread grooves 2, that is, at the root of the tread blocks 1, which can enhance the rigidity of the tread pattern, prevent tread root cracking, and extend the service life of the tire. Furthermore, the reinforcing ribs 3 are arranged around the circumference of the tread blocks 1 to improve the rigidity of the tread pattern.

[0047] Optionally, the tread block 1 includes a head 11 and a body 12. The head 11 is connected to a first end of the body 12 near the centerline of the tread. The second end of the body 12 extends away from the centerline of the tread and, along the forward direction of the agricultural radial tire, the head 11 is located in front of the second end of the body 12, allowing it to contact the ground first and bear a certain force, which helps to distribute the force and further improve grip and wear resistance. Along the width direction perpendicular to the extension direction of the tread block 1, the maximum width of the head 11 is greater than the maximum width of the body 12. The enlarged head 11 can effectively enhance tire grip and improve wear resistance, optimizing stress dispersion. In this embodiment, the minimum width of the head 11 can be equal to the width of the first end of the body 12 to facilitate connection.

[0048] like Figure 3 As shown, the end of the head 11 furthest from the main body 12 includes several straight sections, which are connected end-to-end to form a folded surface for connecting the two sides of the main body 12. This structural design makes the head 11 of the tread block 1 more regular and orderly in shape, further increasing the contact area with the ground, effectively enhancing the grip of the agricultural radial tire and improving wear resistance, while making the connection between the head 11 and the main body 12 more stable. The two sides of the connection between the head 11 and the main body 12 are transitioned by curved surfaces, making the lines of the tread pattern smoother, effectively reducing stress concentration, and further improving anti-skid performance. At the same time, this smooth transition helps to enhance the force transmission efficiency during tire driving, improve grip, and also improve the overall rigidity of the tread pattern, avoiding tread root cracking caused by uneven stress. In this embodiment, the head 11 can extend beyond the center line of the tread by a preset length to increase the contact area with the ground and improve grip performance; the preset length can be set as needed.

[0049] like Figure 3 As shown, the bottom of the tread groove 2 is provided with a step 4, and the two ends of the step 4 are respectively connected to two adjacent tread blocks 1. Each tread groove 2 has at least one step 4, and the steps 4 within the same tread groove 2 are spaced apart. The step 4 enables the bottom of the tread groove 2 to form a tortuous structure. When the tire travels on muddy or other complex road conditions, this tortuous structure can change the flow path and direction of mud, water, and other impurities, hindering the accumulation of impurities within the tread groove 2 and effectively improving the self-cleaning function.

[0050] Optionally, the step 4 includes a first part 41, a second part 42, and a bent part 43. The first end of the first part 41 and the first end of the second part 42 are respectively connected to two adjacent tread blocks 1 located on the same side of the centerline of the tread, providing a stable connection between adjacent tread blocks 1 and ensuring the integrity of the tread pattern structure. The two ends of the bent part 43 are respectively connected to the second ends of the first part 41 and the second end of the second part 42. The extension directions of the first part 41 and the second part 42 are both set at an angle to the extension direction of the bent part 43, and the size of the angle can be set as needed. The first part 41 and the second part 42 are parallel to each other, thus achieving a non-collinear arrangement through the bent part 43. The bent part 43 causes the first part 41 and the second part 42 to be misaligned. This tortuous step 4 design can effectively improve the self-cleaning function of the agricultural radial tire tread pattern. The two ends of the bent part 43 can be connected to the first part 41 and the second part 42 by arc transition; the first part 41, the second part 42 and the bent part 43 can all be arc surface structures so that the transition of the patterned groove 2 at the step 4 is an arc surface, which optimizes the sewage discharge effect and reduces the accumulation of impurities.

[0051] like Figure 3 As shown, a self-cleaning block 5 is provided at the bottom of the tread groove 2, and the self-cleaning block 5 is located at the end of the bottom of the tread groove 2 away from the center line of the tire tread. When the agricultural radial tire is working in the field, the self-cleaning block 5 can eject mud or gravel stuck in the tread groove 2, realize the sewage discharge and self-cleaning function, and also prevent mud from sticking to the tread groove 2, ensuring the normal use of the tire and its grip performance.

[0052] The self-cleaning block 5 includes a first group 51 and a second group 52. The first group 51 is inclined, and the first group 51 and the second group 52 are spaced apart, making the overall structure of the self-cleaning block 5 more reasonable, expanding the self-cleaning range, and further improving the self-cleaning efficiency and anti-mud adhesion effect. Along the forward direction of the agricultural radial tire, the first end of the first group 51 closest to the center line of the tread is located in front of the second end of the first group 51 furthest from the center line of the tread. This arrangement can better utilize the power of the tire when it is moving forward. When the tire encounters mud or gravel in the field, it is more conducive to carrying the mud or gravel out of the tread grooves 2, thus achieving the self-cleaning function. The first group 51 and the second group 52 can be parallel to each other or at an angle, depending on the needs.

[0053] like Figure 3 As shown, optionally, both the first group 51 and the second group 52 include a plurality of protrusions 6. The protrusions 6 are arranged along the extending direction of the first group 51. The number of protrusions 6 in the first group 51 and the second group 52 may be the same or different. The layout of the self-cleaning block 5 can be flexibly adjusted according to actual needs to adapt to different working environments and usage scenarios, and further optimize the self-cleaning and anti-sludge effects.

[0054] It is understandable that the pattern structure also includes necessary structures for connection, support, drive, positioning and limit control, so that the pattern structure can operate normally; the shape, size, material and number of each part of the pattern structure can be determined as needed, as long as the corresponding functions can be achieved.

[0055] The implementation principle of the radial tire tread structure of this application embodiment is as follows: a number of tread blocks 1 are evenly and alternately distributed on both sides of the center line of the tire tread, and tread grooves 2 with a height lower than the tread blocks 1 are provided between adjacent tread blocks 1, so that the tread blocks 1 protrude on the tire tread, increasing the contact area and friction between the tire and the ground, thereby effectively enhancing the grip; at the same time, a number of corresponding reinforcing ribs 3 are provided at the connection between the tread blocks 1 and the tread grooves 2, which can enhance the rigidity of the tread pattern and prevent root cracking of the tread due to stress during use.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
