Description

TECHNICAL FIELD

[0001] The utility model relates to a tire technical field, specifically, relate to a tire tread structure. BACKGROUND

[0002] At present, as the essential component of vehicle, tire directly contacts with ground in the driving process of vehicle to play the role of bearing, braking and driving, vehicle steering and buffering and damping. According to different use scenes and demands, different patterns are arranged on the tread of different kinds of tires to adjust the performance of tire and ensure that tire can meet the corresponding use demand. Among them, the use scene under the mine environment is relatively bad, and correspondingly, the mine tire needs to have higher use safety and driving performance. On the one hand, because the driving road surface of mine environment is mostly mixed road surface with gravel, the road surface is high in danger, the tread pattern structure is easy to wear quickly, the pattern block is easy to fall off, and the tread is easy to be directly punctured. When the above problems occur, the performance of tire will decrease sharply, cannot meet the use demand under the mine environment, is easy to slip and cause safety accidents, seriously affect the personal safety of the driver. On the other hand, the load of mine vehicle is large, and often faces the bad driving condition such as climbing in the driving process, so the mine tire also needs to have high driving performance (such as driving ability, bearing capacity and grip).

[0003] However, with the gradual development of mine vehicle (such as the improvement of load capacity and engine driving performance), the above-mentioned ability (use safety and driving performance) of the mine tire in the prior art has gradually failed to meet the use demand of mine vehicle, especially the design trend of mine tire is: the tread pattern structure formed by fine and dense grooves (such as continuous honeycomb structure) is used to improve the bearing capacity (more uniform bearing) and use safety (fine pattern structure is not easy to collapse and damage, has high puncture resistance) of tire. But the above-mentioned setting has high processing difficulty and is not conducive to improving the grip of tire (small contact area), and has failed to meet the gradually developed mine vehicle. In addition, although the continuous honeycomb pattern can reduce the early damage probability of tire, with the improvement of vehicle bearing capacity (larger load, larger tire pressure), if the continuous honeycomb pattern has collapse or tearing defect, the continuity will be broken, and the anti-puncture and anti-drop performance of the tread will be seriously reduced.

[0037] It should be noted that, unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as generally understood by those skilled in the art to which the present application belongs.

[0038] In the present application, unless otherwise specified, the orientation words such as "up, down" are generally directed to the direction shown in the drawings, or are directed to the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left, right" is generally directed to the left and right shown in the drawings; "inner, outer" refers to the inner and outer relative to the contour of each component, but the above orientation words are not used to limit the present application.

[0039] In order to solve the problems of low safety and driving performance of the mine tire in the prior art, the present application provides a tire tread structure.

[0040] As shown in Figures 1 to 10 The tire tread structure comprises: a raised pattern unit 10 arranged on the tread of the tire, the raised pattern unit 10 having a strip-shaped raised portion 11 arranged along the tire circumferential direction, the strip-shaped raised portion 11 being a plurality of, the plurality of strip-shaped raised portions 11 being arranged in the tire width direction with intervals to form a longitudinal groove 111 around the two adjacent strip-shaped raised portions 11; wherein the raised pattern unit 10 is a plurality of, the plurality of raised pattern units 10 being arranged in the tire circumferential and width directions with intervals; a transverse groove 20 arranged on the tread, one end of the transverse groove 20 extending to the tire shoulder 1, the other end of the transverse groove 20 having a predetermined distance from the center plane S of the tire; the groove wall of the transverse groove 20 is provided with a stepped surface 21 for limiting and stopping the foreign matter on the running surface.

[0041] The raised pattern unit 10 is arranged on the tire tread, the raised pattern unit 10 has strip-shaped protrusions 11 extending along the tire circumferential direction, the strip-shaped protrusions 11 are multiple, and the multiple strip-shaped protrusions 11 are arranged at intervals along the tire width direction to form a longitudinal groove 111 around the two adjacent strip-shaped protrusions 11. The raised pattern unit 10 is multiple, the multiple raised pattern units 10 are arranged at intervals along the tire circumferential direction and the width direction, the transverse groove 20 is arranged on the tire tread, one end of the transverse groove 20 extends to the tire shoulder 1, the other end of the transverse groove 20 has a preset distance from the center surface S of the tire, and the groove wall of the transverse groove 20 is provided with a stepped surface 21 for limiting and stopping the foreign matter on the running surface. In this way, as the only groove structure (transverse groove 20) arranged on the tire tread in the embodiment, the arrangement mode improves the drainage performance of the tire (i.e., extending to the tire shoulder 1) on the one hand, and makes the tire tread a large-area continuous pattern block along the tire circumferential direction on the other hand, which is beneficial to improving the overall rigidity of the tire tread, preliminarily improving the block falling resistance, puncture resistance and load capacity of the tire, and can increase the contact area between the tire tread and the running surface, preliminarily increasing the grip, climbing ability and braking performance of the tire tread. Meanwhile, the raised pattern unit 10 protruding from the tire tread increases the thickness of the tire tread, further improves the block falling resistance and puncture resistance of the tire, and the arrangement of the strip-shaped protrusions 11 of the raised pattern unit 10 and the arrangement mode of the multiple raised pattern units 10 further improve the load capacity of the tire on the one hand, and further improve the driving force, climbing ability and braking performance of the tire on the other hand (i.e., the groove structure formed around the longitudinal groove 111 and the multiple raised pattern units 10 on the tire tread can further increase the interaction force between the tire tread and the running surface). It can be seen that the tire tread structure in the embodiment has high driving performance (grip, climbing ability, braking performance and load capacity) and use safety (block falling resistance and puncture resistance), thereby solving the problems of low use safety and driving performance of the mine tire in the prior art, prolonging the service life of the tire and ensuring the personal safety of the passengers.

[0042] Specifically, the arrangement of the raised pattern unit 10 makes the tire tread need to deform enough before contacting the running surface during rolling, and the deformation of the raised pattern unit 10 buffers the contact between the foreign matter on the running surface and the tire tread, that is, the strip-shaped protrusions 11 can directly contact the sharp corners of the sandstone, effectively avoiding the direct contact between the tire tread and the sharp corners of the sandstone, thereby effectively improving the block falling resistance (block falling resistance) and puncture resistance of the tire.

[0043] Specifically, the transverse groove 20 ensures that the tire has excellent drainage performance, i.e. the liquid between the tread and the running surface will be squeezed, flow into the transverse groove 20, and under the action of centrifugal force when the tire is rolling, flow to the shoulder 1 and finally be thrown out of the tire.

[0044] Specifically, as shown in the expanded view of the tire tread structure, the shoulder 1 is actually located at the side of the tread, i.e. the side of the entire tire, and the transverse groove 20 extending to the shoulder 1 can effectively improve the driving performance of the tire in the middle and later stages of use, i.e. during the continuous wear of the tread, the transverse groove 20 on the shoulder 1 can still form a groove structure on the tread, thereby prolonging the service life of the tire. Figure 1

[0045] Specifically, the setting of the stepped surface 21 can play the role of a sling and a stone, i.e. to avoid stones on the running surface from entering the groove structure (transverse groove 20) directly set on the tread, thereby reducing the possibility of stones scratching the groove bottom and groove wall, and further prolonging the service life of the tire.

[0046] Specifically, the meandering groove formed around the plurality of raised pattern units 10 also improves the passability of the tire on sandy and muddy roads.

[0047] Specifically, compared with the continuous and fine honeycomb pattern structure of the prior art, the raised pattern unit 10 in the present embodiment is in the form of multiple spaced arrangements, i.e. the continuous pattern structure design is not adopted at the initial design stage, and even if the block shedding phenomenon occurs during actual use, it will not have a great impact on the overall performance of the tire.

[0048] As shown in the expanded view of the tire tread structure, Figures 1 to 4 ​As shown, the raised pattern unit 10 comprises a first sub-raised pattern structure 12 having a first mounting layer 121 and a second mounting layer 122 arranged in a spaced manner, and a plurality of strip-shaped protrusions 11 are arranged on the first mounting layer 121 and the second mounting layer 122. Among them, along the tire width direction, the width of the strip-shaped protrusions 11 on the first mounting layer 121 is greater than the width of the strip-shaped protrusions 11 on the second mounting layer 122; and / or, the spacing between the adjacent two strip-shaped protrusions 11 on the first mounting layer 121 is greater than the spacing between the adjacent two strip-shaped protrusions 11 on the second mounting layer 122, so as to form a first visual enhancement structure 13 by the plurality of strip-shaped protrusions 11 on the first mounting layer 121, and form a second visual enhancement structure 14 by the plurality of strip-shaped protrusions 11 on the second mounting layer 122. In this way, the above arrangement can form two visual enhancement structures with different light and shadow effects on the first mounting layer 121 and the second mounting layer 122 respectively by the plurality of strip-shaped protrusions 11 with different widths and / or arrangement densities (the size of the spacing between the adjacent two strip-shaped protrusions 11), so as to improve the visual impact of the tread on the user, and greatly improve the aesthetic degree of the tire.

[0049] As shown in Figure 3 and Figure 4 In the embodiment, the width of the strip-shaped protrusions 11 on the first mounting layer 121 is greater than the width of the strip-shaped protrusions 11 on the second mounting layer 122, and the spacing between the adjacent two strip-shaped protrusions 11 on the first mounting layer 121 is greater than the spacing between the adjacent two strip-shaped protrusions 11 on the second mounting layer 122 (i.e., the arrangement density of the strip-shaped protrusions 11 on the first mounting layer 121 is smaller). In this way, when the natural light beam is irradiated on the raised pattern unit 10, the light is reflected in the longitudinal groove 111 continuously, the strip-shaped protrusions 11 on the first mounting layer 121 have a greater width and a smaller arrangement density, absorb less light beam, and have a relatively larger area brightness, while the strip-shaped protrusions 11 on the second mounting layer 122 have a smaller width and a larger arrangement density, absorb more light, and have a smaller area brightness (darker), so as to form two static light and shadows with different brightnesses on the first sub-raised pattern structure 12, so as to increase the visual impact effect of the raised pattern unit 10 on the user.

[0050] As shown in Figures 1 to 4As shown, both the first mounting layer 121 and the second mounting layer 122 are disposed on the tire tread. The surface of the first mounting layer 121 away from the tire tread forms a first mounting surface 1211 for setting the strip-shaped protrusions 11, and the surface of the second mounting layer 122 away from the tire tread forms a second mounting surface 1221 for setting the strip-shaped protrusions 11. The end of the strip-shaped protrusion 11 away from the tire tread has an arc-shaped contact surface 112 for contacting the driving surface. This arrangement effectively reduces the wear rate of the strip-shaped protrusions 11, thereby extending the service life of the first sub-protrusion tread structure 12.

[0051] In this embodiment, the first mounting layer 121 and the second mounting layer 122 are both plate-shaped rubber structures disposed on the tire tread, which are formed directly during the tire molding process, while the first mounting surface 1211 and the second mounting surface 1221 are the plate surfaces of the two mounting layers that are away from the tire tread, respectively.

[0052] like Figures 1 to 5 As shown, the two ends of the strip-shaped protrusion 11 on the first mounting layer 121 extend to the edge of the first mounting surface 1211, and the two ends of the strip-shaped protrusion 11 on the second mounting layer 122 extend to the edge of the second mounting surface 1221. Along the tire width direction, the second mounting layer 122 is located on one side of the first mounting layer 121; along the tire circumference, the width of at least a portion of the first mounting layer 121 gradually decreases, and the width of at least a portion of the second mounting layer 122 gradually decreases, forming a "mountain"-shaped structure through the first mounting layer 121 and the second mounting layer 122. This arrangement ensures that the dimensions and structures of the strip-shaped protrusion 11, the first mounting surface 121, and the second mounting surface 1221 are matched. Furthermore, because the first mounting layer 121 and the second mounting layer 122 form a "mountain"-shaped structure, the multiple strip-shaped protrusions 11 on the first mounting surface 1211 and the multiple strip-shaped protrusions 11 on the second mounting surface 1221 can simultaneously form a "mountain"-shaped structure. Meanwhile, due to the difference in brightness between the two display areas, the "mountain" shaped structure will present two areas of light and dark, forming a display effect that resembles mountains in the distance, further enhancing the visual impact of the raised pattern unit 10.

[0053] In the embodiment, the first mounting layer 121 is triangular, and the second mounting layer 122 is located on one side of the first mounting layer 121, and the overall structure of the two is consistent with the structure of the two partially overlapped triangles. The display brightness of the strip-shaped protrusions 11 on the first mounting layer 121 is larger to form closer mountains, and the display brightness of the strip-shaped protrusions 11 on the second mounting layer 122 is smaller to form distant mountains that are partially blocked by the closer mountains and have smaller brightness. The two are ingeniously combined, not only embodying a visual impact from far to near and producing a sharp contrast in vision, but also being able to match the mine working environment of the mine tire and further improve the aesthetic degree of the tire.

[0054] In the embodiment, the width of the strip-shaped protrusions 11 on the first mounting layer 121 is twice the width of the strip-shaped protrusions 11 on the second mounting layer 122.

[0055] As shown in Figure 4 and Figure 5 , the overall height of the protrusion pattern unit 10 is H, and the size of the height H is between 0.5mm and 3mm. Among them, the height of the strip-shaped protrusion 11 is 5 / 8H, which ensures that it can have a large enough light beam reflection amount.

[0056] In the embodiment, a groove 16 is formed around between the first mounting layer 121 and the strip-shaped protrusions 11 on the first mounting layer 121 and the second mounting layer 122 and the strip-shaped protrusions 11 on the second mounting layer 122. The depth of the groove 16 is between 1mm and 3mm, and the width is between 0.5mm and 1mm.

[0057] As shown in Figures 1 to 3 and Figure 5 , the protrusion pattern unit 10 further comprises a second sub-protrusion pattern structure 15 located on one side of the first sub-protrusion pattern structure 12 along the tire circumferential direction. The second sub-protrusion pattern structure 15 comprises: a third mounting layer 151 arranged on the tread, and a third mounting surface 1511 formed away from the surface of the tread; and a transverse strip-shaped protrusion 152 arranged on the third mounting surface 1511. Among them, the transverse strip-shaped protrusion 152 is multiple, and the multiple transverse strip-shaped protrusions 152 are arranged in the length direction and / or the width direction of the third mounting surface 1511. In this way, the transverse strip-shaped protrusion 152 can not only improve the driving performance of the tire by improving the interaction force between the tire and the running surface, but also enhance the visual impact to improve the aesthetic degree of the tire.

[0058] In the embodiment, the transverse strip-shaped protrusion 152 comprises a first sub-transverse protrusion 1521 and a second sub-transverse protrusion 1522 connected to each other and arranged at a third included angle A3. In this way, the above arrangement forms a triangular area between the first sub-transverse protrusion 1521 and the second sub-transverse protrusion 1522, and during the rolling of the tire, the light beam irradiated on the transverse strip-shaped protrusion 152 will form periodically appearing darker light spots on the backlight side of the transverse strip-shaped protrusion 152, thereby forming a dynamic light and shadow effect, further improving the visual impact of the protrusion pattern unit 10 and the aesthetic cost of the tire. At the same time, the triangular area is arranged to make the darker light spots present a small block structure to form a visual expression effect similar to stones, thereby being able to match the mine working environment of the mining tire.

[0059] In the embodiment, the third included angle A3 is between 30° and 60°.

[0060] In the embodiment, the width of the transverse strip-shaped protrusion 152 is between 1mm and 2mm.

[0061] In the embodiment, the end surface of the transverse strip-shaped protrusion 152 away from the third mounting surface 1511 is also an arc surface.

[0062] In the embodiment, the plurality of transverse strip-shaped protrusions 152 are arranged in a matrix, and the spacing between two adjacent transverse strip-shaped protrusions 152 is between 0.5mm and 1mm.

[0063] In the embodiment, the plurality of transverse strip-shaped protrusions 152 are arranged in a matrix.

[0064] Specifically, compared with the dynamic light and shadow formed by the transverse strip-shaped protrusion 152, the first sub-protrusion pattern structure 12 forms a static light and shadow, that is, the arrangement density of the strip-shaped protrusion 11 is much larger than that of the transverse strip-shaped protrusion 152, and the longitudinal extension of the strip-shaped protrusion 11 can weaken the dynamic change of the light beam reflection amount. In this way, the above arrangement makes the protrusion pattern unit 10 as a whole present a static light and shadow of far and near mountains, and the static light and shadow of far and near mountains will periodically appear a dynamic light and shadow of stones, thereby being able to highly match the mine working environment of the mining tire, highlighting the use scene of the tire, and greatly improving the appearance of the tire.

[0065] In this embodiment, the third mounting layer 151 is a plate-shaped rubber structure disposed on the tire tread, which is formed directly during the tire molding process. Specifically, the third mounting layer 151 has a triangular structure, and the area where the first mounting layer 121, the second mounting layer 122, and the third mounting layer 151 are located presents a square structure on the tire tread as a whole. However, the first sub-protruding tread structure 12 is not symmetrical with the second sub-protruding tread structure 15 due to its mountain-shaped structural design.

[0066] like Figures 1 to 3 As shown, multiple raised tread pattern units 10 are uniformly arranged along the tire circumference and tire width directions. Along the tire width direction, in two adjacent rows of raised tread pattern units 10, one row and the other row have a predetermined misalignment distance along the tire circumference, so that any raised tread pattern unit 10 corresponds to two adjacent raised tread pattern units 10 in its adjacent row along the tire width direction. Specifically, the second sub-raised tread pattern structure 15 of the raised tread pattern unit 10 and the first sub-raised tread pattern structure 12 corresponding to the raised tread pattern unit 10 are correspondingly arranged, with a distance 'a' between the second sub-raised tread pattern structure 15 and the corresponding first sub-raised tread pattern structure 12. The first sub-protruding tread structure 12 of the raised tread unit 10 and the second sub-protruding tread structure 15 of another raised tread unit 10 corresponding to the raised tread unit 10 are respectively arranged, with a distance b between the first sub-protruding tread structure 12 and the corresponding second sub-protruding tread structure 15. The distances a and b satisfy: 1.1b ≤ a ≤ 1.3b. In this way, the raised tread units 10 uniformly arranged on the tire surface help to improve the uniformity of tire load. Since the first sub-protruding tread structure 12 and the second sub-protruding tread structure 15 have different structures, their driving performance improvement capabilities are also different. By staggering the arrangement and limiting the values ​​of the distances a and b, it can be ensured that the raised tread units 10 form a uniform driving performance improvement on the tire surface, further improving the driving performance of the tire.

[0067] In this embodiment, the distances a and b satisfy the condition: a = 1.2b.

[0068] like Figure 2 As shown, both sides of the center surface S have multiple explosion-proof tread units 30 arranged along the tire circumference. Each explosion-proof tread unit 30 includes at least two complete raised tread units 10 and a first sub-raised tread structure 12 and a second sub-raised tread structure 15 located between two adjacent complete raised tread units 10. The first sub-raised tread structure 12 and the second sub-raised tread structure 15 located between two adjacent complete raised tread units 10 are respectively located in two different raised tread units 10.

[0069] In this embodiment, the explosion-proof tread unit 30 is provided with three raised tread units 10, namely two complete raised tread units 10 and a first sub-raised tread structure 12 and a second sub-raised tread structure 15 located between the two complete raised tread units 10. The center point of the first sub-raised tread structure 12 between the two complete raised tread units 10 coincides with the center point of the upper boundary of the explosion-proof tread unit 30, and the center point of the second sub-raised tread structure 15 between the two complete raised tread units 10 coincides with the center point of the lower boundary of the explosion-proof tread unit 30, forming a completely symmetrical explosion-proof tread unit 30. This arrangement allows the explosion-proof tread unit 30 to have a more uniform interaction force on the driving surface, ensuring that the tire tread structure will not be punctured, torn, or chipped, further improving tire safety and extending tire lifespan.

[0070] In this embodiment, the explosion-proof pattern unit 30 is rectangular in shape, with a length of 120mm to 130mm and a width of 35mm to 45mm, to match the actual structure and size of the tire.

[0071] like Figure 2 As shown, it illustrates three adjacent explosion-proof patterned units 30. In this embodiment, within any one explosion-proof patterned unit 30, a complete raised patterned unit 10 located on one side is correspondingly arranged with an adjacent incomplete first sub-raised patterned structure 12 and an incomplete second sub-raised patterned structure 15. That is, there is a distance a between the second sub-raised patterned structure 15 of the complete raised patterned unit 10 and the first mounting layer 121 of the incomplete first sub-raised patterned structure 12, and a distance b between the second mounting layer 122 of the first sub-raised patterned structure 12 of the complete raised patterned unit 10 and the incomplete second sub-raised patterned structure 15.

[0072] In this embodiment, the tire tread structure located on one side of the center plane S and the tire tread structure located on the other side of the center plane S are rotationally symmetrical. In the tire tread structure located on one side of the center plane S, there is a second opening direction S2 between the first lateral groove 22 and the second lateral groove 23. The second opening direction S2 is opposite to the direction in which the width of the first sub-protruding tread structure 12 decreases. In this way, the orientation of the multi-layered, mountain-shaped first sub-protruding tread structure 12 is always the same as the bending direction of the lateral groove 20. This not only enhances the visual effect but also enhances the tread's grip and driving force, resulting in more outstanding sports performance.

[0073] In this embodiment, a first opening direction S1 is provided between the first sub-lateral protrusion 1521 and the second sub-lateral protrusion 1522, and the first opening direction S1 is opposite to the second opening direction S2.

[0074] As shown in Figure 1 and Figures 6 to 10 , along the tire width direction, the transverse groove 20 includes the first transverse groove 22, the second transverse groove 23 and the third transverse groove 24 which are interconnected, the second transverse groove 23 is located between the first transverse groove 22 and the third transverse groove 24, the third transverse groove 24 is located on the shoulder 1, and the first transverse groove 22 has a preset distance between the end away from the second transverse groove 23 and the center surface S. Among them, the first transverse groove 22 is arranged at a first included angle A1 between the extension direction and the tire width direction, the first included angle A1 satisfies: 10°≤A1≤30°, the second transverse groove 23 is arranged at a second included angle A2 between the extension direction and the tire width direction, the second included angle A2 satisfies: 10°≤A2≤20°, and the inclination direction of the first transverse groove 22 is opposite to that of the second transverse groove 23. In this way, the above arrangement makes the transverse groove 20 as a whole be a broken line groove and an octagonal structure, and further ensures that the transverse groove 20 can more evenly balance the tread rigidity to increase the interaction force between the tire and the running surface and improve the driving performance of the tire.

[0075] Specifically, the tread structure is actually molded by nine equal parts, and the circumferential pitch (PN) is 30 pitches Figure 1 , and a local schematic view of the tire tread structure in 2 pitches is shown), which is divided into upper and lower molds in one pitch, and the upper and lower molds have the same anti-burst pattern unit 30, and there is no gap between the anti-burst pattern units 30. The rectangular array anti-burst pattern unit 30 can be completely coincided with the tire tread structure of the other half mold by rotating 180° with the octagonal transverse groove 20, which is center-symmetric. The overall symmetric arrangement of the tread ensures the uniform load-bearing performance of the tire and improves the visual impact of the tire.

[0076] In this embodiment, the overall depth of the transverse groove 20 is between 20mm and 24mm, and the overall width is between 30mm and 38mm. The width-depth ratio of the transverse groove 20 should be between 1.25 and 1.9. The overall large-width and large-depth groove arrangement ensures that it has a high enough rigidity balance capability.

[0077] In this embodiment, an arc-shaped groove section is further arranged between the first transverse groove 22 and the second transverse groove 23 to realize the circular arc transition therebetween.

[0078] In this embodiment, the radius of the arc-shaped groove section should be greater than 35mm.

[0079] In this embodiment, the length of the second transverse groove 23 is between 60mm and 70mm, and the length of the first transverse groove 22 is between 25mm and 30mm.

[0080] As shown in Figure 6 , Figure 7 , Figure 8 andFigure 10 As shown, the step surface 21 is arranged on the groove wall of the first transverse groove 22 and the groove wall of the second transverse groove 23. The step surface 21 arranged on the groove wall of the first transverse groove 22 is arranged in a "U" shape. The step surface 21 is multiple, and the multiple step surfaces 21 are arranged in the depth direction of the transverse groove 20. In this way, on the one hand, the area of the step surface 21 can be increased to ensure that it can effectively limit and stop the foreign matter; on the other hand, the arrangement of multiple step surfaces 21 can block the foreign matter multiple times during the process of entering the transverse groove 20, further improving the anti-stone and stone-removing performance, wear resistance and service life of the tire.

[0081] As shown in the drawings, Figure 6 The end groove wall of the first transverse groove 22 in the embodiment is also provided with a step surface 21 to increase the arrangement range and area of the step surface 21.

[0083] As shown in the drawings, Figure 7 In the cross section of the transverse groove 20, the adjacent two step surfaces 21 are connected through the groove wall of the transverse groove 20, at least one connection between the step surface 21 and the groove wall of the transverse groove 20 is provided with an arc transition surface, the groove wall of the transverse groove 20 and the normal line of the transverse groove 20 form a fourth included angle A4, and the fourth included angle A4 satisfies: 20°≤A4≤70°. In this way, the above-mentioned arrangement effectively avoids the defects such as shoulder cracking caused by stress concentration at the bending part of the groove wall, further prolongs the service life of the tire.

[0084] Specifically, Figure 6 The radius of the arc transition surface between the step surface 21 at the end of the first transverse groove 22 and the groove wall should be greater than or equal to 5mm, and Figure 7 The radius of the arc transition surface between the step surface 21 at the end of the first transverse groove 22 and the groove wall should be greater than or equal to 5mm, and

[0085] As shown in the drawings, Figure 8 , Figure 9 and Figure 10As shown, along the extending direction of the transverse groove 20, the first transverse groove 22 and the second transverse groove 23 both have the communicating section 25 and the mounting section 26 which are communicated with each other, the communicating section 25 is multiple, the mounting section 26 is multiple, the mounting section 26 is located between two adjacent communicating sections 25, and the groove bottom of the communicating section 25 is an arc surface.

The connecting structure 50 is arranged on the groove bottom of the second mounting section, and the connecting structure 50 is connected by two groove walls of the second mounting section to strengthen the structure of the second mounting section. In this way, the arc groove bottom of the communicating section 25 can further avoid stress concentration, and the service life of the tire is prolonged. Meanwhile, the above-mentioned setting can further reduce the embedding probability of the stone on one hand through the stone structure 40, and on the other hand, the stone structure 40 and the connecting structure 50 can both improve the structural strength at the groove bottom to prevent the groove bottom from being deformed and prolong the service life of the tire.

[0086] In the embodiment, the connecting structure 50 is arranged at the communicating position of the second transverse groove 23 and the third transverse groove 24, so that the connecting structure 50 can also enhance the support performance of the shoulder part, so that the shoulder pattern connection is more reliable.

[0087] In the embodiment, the connecting structure 50 is a reinforcing rib.

[0088] In the embodiment, the connecting structure 50 is arranged at the communicating position of the second transverse groove 23 and the third transverse groove 24, so that the connecting structure 50 can also enhance the support performance of the shoulder part, so that the shoulder pattern connection is more reliable.

Among them, the raised pattern unit is multiple, and the multiple raised pattern units are arranged at intervals along the tire circumferential direction and the width direction, the transverse groove is arranged on the tread, one end of the transverse groove extends to the tire shoulder, and the other end has a preset distance from the center surface S of the tire, and the groove wall of the transverse groove is provided with a stepped surface for limiting and stopping foreign matter on the running surface. In this way, as the only groove structure (transverse groove) arranged on the tread in the application, its arrangement mode on the one hand improves the drainage performance of the tire (i.e. extends to the tire shoulder); on the other hand, the tread is a large-area continuous pattern block along the tire circumferential direction, which not only helps to improve the overall rigidity of the tread, and preliminarily improves the block drop resistance, puncture resistance and load capacity of the tire, but also increases the contact area between the tread and the running surface, and preliminarily increases the grip, climbing ability and braking performance of the tread.

It can be seen that the tire tread structure in the application has high driving performance (grip, climbing ability, braking performance and load capacity) and use safety (block drop resistance and puncture resistance), thereby solving the problems of low use safety and driving performance of the mine tire in the prior art, prolonging the service life of the tire and ensuring the personal safety of the passengers.
