[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The following will refer to the drawings and combine with the embodiments to detail the present utility model.

[0028] As Figures 1 to 3 shown, for the tire of the present utility model, a pattern structure is provided on the tread. The pattern structure includes a plurality of transverse grooves 10. The plurality of transverse grooves 10 are arranged at intervals along the circumferential direction of the tire on the tread of the tire. The two ends of each transverse groove 10 respectively extend from the crown of the tire to two shoulders, so as to divide the tread into a plurality of pattern strips 110; a plurality of longitudinal groove groups 20. The plurality of longitudinal groove groups 20 are arranged in one-to-one correspondence with the plurality of pattern strips 110. Each longitudinal groove group 20 includes a plurality of longitudinal grooves 210 arranged at intervals along the extending direction of the corresponding pattern strip 110, so as to divide the corresponding pattern strip 110 into a plurality of pattern blocks 120; a first side pattern group. The first side pattern group includes a plurality of first side pattern parts. The plurality of first side pattern parts are arranged in one-to-one correspondence on the plurality of pattern strips 110. Each first side pattern part includes two first shoulder side patterns 30. The two first shoulder side patterns 30 are respectively arranged at the two ends of the corresponding pattern strip 110; wherein, the first shoulder side pattern 30 is a stepped groove.

[0029] In this way, by providing a plurality of transverse grooves 10 to divide the tread of the tire into a plurality of pattern strips 110, and providing a plurality of longitudinal groove groups 20 to further divide the tread of the tire into a plurality of pattern blocks 120, and reasonably distributing the shape and size of the pattern blocks 120, the rigidity and grip of the pattern blocks 120 are increased, making the tire more suitable for mining areas; and a plurality of first side pattern groups are provided at the two ends of the pattern strip 110. By setting the two first shoulder side patterns 30 of the first side pattern part as stepped grooves, the heat dissipation of the tire shoulder can be effectively reduced, preventing failures such as tire blowout and shoulder void; in addition, the above-mentioned stepped groove can also be used for warning the stage wear depth of the tire. When the stepped groove is gradually worn flat layer by layer, it indicates that the pattern blocks on the tire surface have been basically worn flat, and the tire should be replaced in time, improving the wear resistance of the tire and solving the problem of short service life of the tire in the prior art.

[0030] Specifically, each longitudinal groove group 20 includes four longitudinal grooves 210, and the four longitudinal grooves 210 divide the tread of the tire into a left shoulder tread block, a left main tread block, a middle tread block, a right main tread block, and a right shoulder tread block; among them, the sea-land ratio range of the main tread blocks (including the left main tread block, the middle tread block, and the right main tread block) is greater than or equal to 50% and less than or equal to 60%, which is overall at a relatively low ratio, enhancing the drainage ability of the tire; and the overall heat dissipation ability of the tire tread of the present utility model is good, and the durability performance is excellent, which can effectively reduce the risks of shoulder void and tire burst.

[0031] In the tire of the present utility model, the designs of the left shoulder tread block, the left main tread block, the right main tread block, and the right shoulder tread block are all asymmetric polygon styles, the middle tread block is a centrosymmetric structure, and the arrangement of the multiple tread blocks 120 is relatively loose. When the tire of the present utility model is a tire with an ultra-wide tread surface in specifications such as 425 / 65R22.5 and 445 / 65R22.5, the tread blocks 120 thereon need to be correspondingly increased to ensure the rigidity of the tread blocks 120 and avoid the phenomenon of tread block chipping due to insufficient rigidity during driving.

[0032] As Figure 1 and Figure 2 shown, the tread structure further includes a plurality of elastic stone block groups 40. The plurality of elastic stone block groups 40 are arranged in one-to-one correspondence with the plurality of transverse grooves 10, and each elastic stone block group 40 includes a plurality of elastic stone blocks 410 arranged at intervals in sequence along the extending direction of the corresponding transverse groove 10. Each elastic stone block 410 is arranged at the bottom of the corresponding transverse groove 10, and a connecting portion 420 is arranged between any two adjacent elastic stone blocks 410.

[0033] As Figure 2 shown, the present utility model increases the stone discharging property of the tread structure by adding the elastic stone block groups 40 at the bottom of the transverse grooves 10, and adds the connecting portion 420 between any two adjacent elastic stone blocks 410 to prevent the rounding of the corners of the elastic stone blocks during the tire production process, making the tire more beautiful.

[0034] Optionally, the connecting portion 420 is a connecting rib.

[0035] Optionally, the ratio of the height of the elastic stone block 410 to the depth of the transverse groove 10 is 0.16; and / or the ratio of the height of the connecting portion 420 to the depth of the transverse groove 10 is 0.16; and / or the value range of the width x of the connecting portion 420 is greater than or equal to 0.3 mm and less than or equal to 0.5 mm; and / or the width x of the connecting portion 420 is less than the width of the elastic stone block 410.

[0036] As Figure 1As shown, the pattern structure further includes a second side flower group. The second side flower group includes a plurality of second side flower parts. The plurality of second side flower parts are correspondingly arranged on a plurality of transverse grooves 10. Each second side flower part includes two second shoulder side flowers 50, and the two second shoulder side flowers 50 are respectively arranged at both ends of the corresponding transverse groove 10.

[0037] As Figure 1 and Figure 3 shown, the first shoulder side flower 30 includes a first groove 310, and the depth of the first groove 310 is 0.75 times the depth of the transverse groove 10.

[0038] A second groove 320, a part of the second groove 320 overlaps with the first groove 310, and the other part of the second groove 320 is located on the side of the first groove 310 close to the plurality of longitudinal groove groups 20. The depth of the second groove 320 is 0.5 times the depth of the transverse groove 10.

[0039] A third groove 330, a part of the third groove 330 overlaps with the second groove 320, and the other part of the third groove 330 is located on the side of the second groove 320 close to the plurality of longitudinal groove groups 20. The depth of the third groove 330 is 0.25 times the depth of the transverse groove 10.

[0040] Specifically, the value range of the ratio between the maximum width w of the first shoulder side flower 30 and the width of the corresponding tread bar 110 is greater than or equal to 1 / 4 and less than or equal to 1 / 3; and / or the value range of the angle b between the two groove wall surfaces of the first groove 310 is greater than or equal to 6° and less than or equal to 10°; and / or the value range of the angle b between the two groove wall surfaces of the second groove 320 is greater than or equal to 6° and less than or equal to 10°; and / or the value range of the angle b between the two groove wall surfaces of the third groove 330 is greater than or equal to 6° and less than or equal to 10°.

[0041] As Figure 3 shown, the design of the first shoulder side flower 30 can further improve the heat dissipation and durability of the left and right shoulder tread blocks of the tire, and prevent failures such as tire blowout and shoulder void; and the above-mentioned stepped grooves can be used for warning the stage wear depth of the tire. The depth of each layer of the groove is 1 / 4 of the depth of the transverse groove 10. When the first groove 310 is worn flat, that is, when the depth of the transverse groove 10 remains only 1 / 4, it indicates that the tread block 120 on the tire surface has been basically worn flat, and the tire should be switched to the trailer wheel position for use.

[0042] As Figure 1 shown, the transverse groove 10 includes a plurality of connecting groove segments 130 connected in sequence along its extending direction. Among them, the angle between any two adjacent connecting groove segments 130 is an obtuse angle; and / or the transverse groove 10 is a centrosymmetric structure.

[0043] Preferably, the angle between any two adjacent connecting groove sections 130 is greater than 135°; and / or the width of the connecting groove section 130 is in the range of greater than or equal to 20 mm and less than or equal to 26 mm; and / or the depth of the connecting groove section 130 is greater than the depth of the longitudinal groove 210, and the difference between the depth of the connecting groove section 130 and the depth of the longitudinal groove 210 is greater than or equal to 3 mm and less than or equal to 5 mm; and / or the angle a between the two groove walls of the connecting groove section 130 is in the range of greater than or equal to 25° and less than or equal to 35°; and / or the depth h of the connecting groove section 130 is in the range of greater than or equal to 22 mm and less than or equal to 26 mm.

[0044] Specifically, the tire tread is provided with a plurality of transverse grooves 10 and a plurality of longitudinal groove groups 20 which penetrate the tread transversely from the shoulder to the crown. Each longitudinal groove group 20 is arranged at intervals along the extension direction of the corresponding tread strip 110. The transverse groove 10 includes a plurality of connecting groove segments 130 which are connected in sequence along its own extension direction. The shapes of the plurality of connecting groove segments 130 are similar, and the angle between any two adjacent connecting groove segments 130 is an obtuse angle greater than 135°. The beneficial effect of using the above-mentioned plurality of connecting groove segments 130 as an obtuse angle structure is that under the premise of ensuring the stability of straight-line driving, the gripping ability is stronger than that of the linear tread groove. In addition, the large obtuse angle design can also avoid the phenomenon of insufficient rubber and air pockets during molding and vulcanization, thereby reducing the probability of waste and defective tires.

[0045] Specifically, the width of the connecting groove section 130 is greater than or equal to 20 mm and less than or equal to 26 mm. The larger width of the connecting groove section 130 can improve the drainage performance of the tire and optimize the angle of the groove wall of the connecting groove section 130, effectively preventing stone clamping, enhancing the drainage performance of the tire, and improving the wet grip ability of the tire.

[0046] Preferably, the width of the connecting groove section 130 at the shoulder of the tire is greater than or equal to 24 mm and less than or equal to 26 mm, and the width of the connecting groove section 130 at the middle of the tire is greater than or equal to 20 mm and less than or equal to 24 mm.

[0047] Specifically, the multiple longitudinal grooves 210 of the longitudinal groove group 20 include a plurality of first longitudinal grooves and a plurality of second longitudinal grooves respectively located on opposite sides of the center plane S of the tire; wherein, the angle between two adjacent first longitudinal grooves is an acute angle; and / or the angle between two adjacent second longitudinal grooves is an acute angle; and / or the plurality of first longitudinal grooves and the plurality of second longitudinal grooves are centrally symmetrically arranged; and / or the angle between the two groove wall surfaces of the longitudinal groove 210 is in the range of greater than or equal to 25° and less than or equal to 35°.

[0048] like Figure 1As shown, the tread pattern structure of the entire tire is a centrally symmetric structure, which can effectively avoid the problem of incorrect tire installation during tire mounting and improve the installation efficiency.

[0049] Optionally, a tread bar 110 and an adjacent transverse groove 10 form a tread pitch. The tire includes a first tread pitch, a second tread pitch, and a third tread pitch; wherein, the lengths of the first tread pitch, the second tread pitch, and the third tread pitch are P1, P2, and P3 respectively; wherein, the value range of P1:P2:P3 is [1.04, 1.12]:[1.00, 1.04]:[1.00, 1.12]; and / or the numbers of the first tread pitch, the second tread pitch, and the third tread pitch are N1, N2, and N3 respectively; wherein, N1:N2:N3 = 1:2:1.

[0050] Specifically, the tread pattern is a variable pitch design, and the pitch units of three unequal pitches are arranged irregularly along the circumferential direction of the tire, which can better disperse the acoustic wave energy and reduce the noise peak value.

[0051] The present utility model includes a plurality of transverse grooves 10 and a plurality of longitudinal groove groups 20, and deeper transverse grooves 10 and a wider tread surface are provided. Such a design can ensure the puncture resistance, durability, and heat dissipation performance of the tire tread, and further increase the grip and anti-hydroplaning performance of the tire.

[0052] Specifically, the tire of the present utility model adopts a plurality of transverse grooves 10 and a plurality of longitudinal groove groups 20, which improves the heat dissipation capacity of the tire, reduces the overall saturation of the tread pattern structure, and reduces the risk of tire thermal damage; since the tires applicable to mining areas are extremely prone to picking up stones, a stone-block elastic group 40 is designed at the bottom of the transverse groove 10 to prevent picking up stones and puncture of the groove bottom, and a connecting part 420 is provided between two elastic stones 410 to avoid the occurrence of rounded corners of the discharged stones during the vulcanization process of tire production, enhancing the aesthetics of the tire.

[0053] The larger tread blocks 120 of the present utility model increase the driving force and tread rigidity, avoid the occurrence of tread blooming during use, and a first side tread group is provided at the shoulder. On the one hand, it increases the heat dissipation performance of the tread blocks 120 at the shoulder of the tire, making the tire more durable. On the other hand, each step of the stepped groove can be used as a wear mark warning for the tread depth, and at the same time, it enhances the overall aesthetic effect of the tread.

[0054] From the above description, it can be seen that the above embodiments of the present utility model achieve the following technical effects:

[0055] The tire of the present utility model has a tread pattern structure on its tread. The tread pattern structure includes a plurality of transverse grooves 10. The plurality of transverse grooves 10 are arranged at intervals along the circumferential direction of the tire on the tread of the tire. Both ends of each transverse groove 10 extend from the crown of the tire to two shoulders, so as to divide the tread into a plurality of tread blocks 110; a plurality of longitudinal groove groups 20. The plurality of longitudinal groove groups 20 are arranged in one-to-one correspondence with the plurality of tread blocks 110. Each longitudinal groove group 20 includes a plurality of longitudinal grooves 210 arranged at intervals along the extending direction of the corresponding tread block 110, so as to divide the corresponding tread block 110 into a plurality of tread segments 120; a first side tread group. The first side tread group includes a plurality of first side tread parts. The plurality of first side tread parts are arranged in one-to-one correspondence on the plurality of tread blocks 110. Each first side tread part includes two first shoulder side treads 30. The two first shoulder side treads 30 are respectively arranged at both ends of the corresponding tread block 110; wherein, the first shoulder side tread 30 is a stepped groove.

[0056] In this way, by arranging a plurality of transverse grooves 10 to divide the tread of the tire into a plurality of tread blocks 110, arranging a plurality of longitudinal groove groups 20 to further divide the tread of the tire into a plurality of tread segments 120, and reasonably distributing the shape and size of the tread segments 120, the rigidity and grip of the tread segments 120 are increased, making the tire more suitable for mining areas; and a plurality of first side tread groups are arranged at both ends of the tread block 110. By setting the two first shoulder side treads 30 of the first side tread part as stepped grooves, the heat dissipation of the tire shoulder can be effectively reduced, and faults such as tire blowout and shoulder void can be prevented from occurring; in addition, the above-mentioned stepped groove can also be used for warning the stage wear depth of the tire. When the stepped groove is gradually worn flat layer by layer, it indicates that the tread segments on the tire surface have been basically worn flat, and the tire should be replaced in time, improving the wear resistance of the tire and solving the problem of short service life of the tire in the prior art.
