DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is described and illustrated in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

In addition, it can be understood that although the efforts made in this development process may be complicated and lengthy, for ordinary technicians in this field related to the content disclosed by the utility model, some changes in design, manufacturing or production based on the technical content disclosed by the utility model are just conventional technical means, and should not be understood as the content disclosed by the utility model is insufficient.

[0030] Reference to "embodiments" in the present invention means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in the present invention may be combined with other embodiments without conflict.

[0031] A new energy bus tire pattern includes a tread and also includes:

[0032] Three longitudinal grooves 1 are longitudinally distributed on the tread, and each longitudinal groove 1 is in a continuous multi-fold line structure; Figure 1 As shown, the three longitudinal grooves 1 have the same broken line direction, angle size, and groove depth. At the same time, a structure with a reduced diameter from the tread to the inner direction of the tire is adopted, which can prevent the groove cracks caused by frequent turns of buses and reduce the stone clamping phenomenon, avoiding cuts from debris and affecting the service life of the tire. At the same time, the three longitudinal grooves 1 account for less than 20% of the overall tread area, so that the tread pattern saturation can reach more than 80%, and then through the larger saturation of the pattern blocks, the tread wear resistance is better to ensure a higher mileage.

[0033] A plurality of transverse grooves 5 are provided on the tire tread block 2 between adjacent longitudinal grooves 1, and each transverse groove 5 is in a V-shaped structure;

[0034] The longitudinal groove 3 in the tire is connected to the adjacent transverse grooves 5;

[0035] The lateral groove 4 in the tire is cross-connected with the longitudinal groove 3 in the tire, and its two ends are respectively connected with the corresponding longitudinal groove 1.

[0036] The V-shaped transverse grooves 5 can well ensure the grip performance of the tire during driving. At the same time, by further matching the longitudinal grooves 3 and the transverse grooves 4 in the tire, a transverse and longitudinal staggered groove driving is formed, which further provides stronger grip and higher driving force to ensure the stability and safety of control.

[0037] In some embodiments, one end of the transverse groove 5 is connected to the position of the outer inflection point 6 of the longitudinal groove 1 corresponding to it, and the other end of the transverse groove 5 is connected to the position between the outer inflection point 6 of the longitudinal groove and the inner inflection point 7 of the longitudinal groove 1 corresponding to it.

[0038] Combination Figure 1It can be obtained that the inner end of the transverse groove 5 is located at the outer inflection point 6 of the longitudinal groove 1 of the middle longitudinal groove, and the outer end of the transverse groove 5 is located between the outer inflection point 6 of the longitudinal groove 1 and the inner inflection point 7 of the longitudinal groove. Similarly, the opposite setting can also be made.

[0039] In some embodiments, one end of the longitudinal groove 3 in the tire is connected to the corresponding transverse groove 5 at the outer inflection point 8 of the transverse groove, and the other end of the longitudinal groove 3 in the tire is connected to the corresponding transverse groove 5 at the non-transverse groove inner inflection point 9.

[0040] In some embodiments, one end of the tire lateral groove 4 is connected to the position of the outer inflection point 6 of the longitudinal groove 1 corresponding to it, and the other end of the tire lateral groove 4 is connected to the position between the outer inflection point 6 of the longitudinal groove and the inner inflection point 7 of the longitudinal groove 1 corresponding to it.

[0041] The longitudinal groove 3 and the transverse groove 4 are arranged in the same manner as the transverse groove 5, and also adopt a structural design in which one is located at the inflection point and the other is not located at the inflection point.

[0042] By setting the above-mentioned connection points, not only the overall conductive structure is formed to avoid squeezing the internal air and reduce the generation of noise, but also the force is made more balanced and stable, and the support is better.

[0043] In addition, the tire longitudinal groove 3, tire transverse groove 4 and transverse groove 5 located on both sides of the middle longitudinal groove 1 are arranged in a central symmetric manner. The wear resistance is further improved by the central symmetry, making the wear surface more uniform when worn.

[0044] In some embodiments, the longitudinal groove 3 in the tire is in a straight-line structure. The middle of the transverse groove 4 in the tire is in a straight-line structure and crosses and communicates with the longitudinal groove 3 in the tire, and its two ends are in an L-shaped structure. The above overall structure forms a cross-shaped structure between the longitudinal groove 3 in the tire and the transverse groove 4 in the tire, which can effectively separate the pattern blocks, reduce their rigidity and improve comfort, and ensure their grip performance.

[0045] In some embodiments, the width ratio of the middle tread block 2 between adjacent longitudinal grooves 1 to the shoulder tread block 2 outside the longitudinal groove 1 is 1:(1.15-1.35). This increases the effective contact area of ​​the tire and improves tire stability; the running surface design is widened, and the ratio of the running surface width to the section width is more than 85%. With a reasonable running surface arc and running surface height design, the tread wear is more uniform, the tire wear is prevented from being deformed and unevenly worn, and the mileage is effectively increased.

[0046] A tire comprises: a new energy bus tire pattern as in any one of the above embodiments, and a plurality of inwardly recessed grooves 10 are distributed on the circumference of the tire sidewall.

[0047] Specifically, four grooves 10 may be provided. The grooves 10 are inwardly concave cylindrical structures with a diameter of 8mm-15mm and a depth of 2mm-6mm. By providing the grooves 10, the wear of the sidewalls may be monitored at all times. If the tire is worn to the bottom of the grooves 10, it indicates that a tire change is required.

[0048] At the same time, corresponding heat dissipation holes can also be opened on the sidewalls to help dissipate heat from the shoulders and avoid causing shoulder and crown hollows.

[0049] The distribution pitch between the pattern blocks separated by the transverse grooves 5 in the longitudinal direction adopts a variable pitch method, that is, the pitch will be changed and adjusted to avoid the occurrence of resonance and thus reduce tire noise.

[0050] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
