Description

Technical Field

[0001] The utility model belongs to the technical field of tire treads, and particularly relates to a tire tread and a four-season light truck tire. Background Art

[0002] The characteristics of light trucks are that their general load capacity is between 2 and 6 tons, which can meet various needs such as urban distribution and short-distance transportation. They will not be unable to meet the transportation demand due to too small a load weight, nor will they be restricted due to too large a load weight. Their overall body is relatively small to meet flexible driving on urban streets and complex road conditions.

[0003] Due to the particularity and complexity of road conditions, traditional light truck tires usually need to be replaced according to seasons (such as winter tires or summer tires) to ensure safety and stability in the above driving environments. At present, there are few four-season tires specifically designed for the road conditions of light trucks on the market, and their adaptability is not high, especially their performance on wet or snowy roads is relatively poor. Summary of the Utility Model

[0004] The details of one or more embodiments of the present utility model are set forth in the following drawings and description to make other features, objects, and advantages of the present application more concise and understandable.

[0005] The present utility model provides a tire tread and a four-season light truck tire. By the staggered arrangement of the middle tread blocks and the central symmetry arrangement of the side tread blocks, the grounding area of the tire is effectively increased, and at the same time, the pressure distribution is optimized to ensure the grip and handling performance of the tire on dry roads; by designing appropriate transverse steel sheets and longitudinal steel sheets for different positions and matching corresponding specific structures to form multi-point contact type tiny "anchor" points, the grip of the tire is enhanced, so as to be applicable to slightly snow-covered or icy road conditions, ensuring that the tire can still maintain excellent handling performance in low-temperature environments and meeting the use requirements for four-season tires.

[0006] The present utility model discloses a tire tread, comprising:

[0007] A pair of middle tread blocks, which are arranged on both sides of the central longitudinal groove on the tread surface in a left-right staggered manner, and are provided with multiple groups along the movement direction of the tire;

[0008] A pair of side tread blocks, which are arranged on both sides of the central longitudinal groove on the tread surface in a centrally symmetric manner, and are located outside the pair of middle tread blocks, and are provided with multiple groups along the movement direction of the tire;

[0009] Transverse steel sheets, which are in a multi-folded structure shape and are horizontally penetrated through each of the middle tread blocks and semi-penetrated through each of the side tread blocks;

[0010] The longitudinal steel sheets are in a straight-line segment structure and longitudinally penetrate through each area after the transverse steel sheets divide the middle tread blocks, and the longitudinal steel sheets in each area are not collinear.

[0011] In some embodiments, the middle transverse grooves between the vertically adjacent middle tread blocks are in a wavy structure with an upper opening and a lower opening; the side transverse grooves between the vertically adjacent side tread blocks are in an arc-shaped structure.

[0012] In some embodiments, the inner end of the transverse steel sheet on the side tread block communicates with the side longitudinal groove between the middle tread block and the side tread block, and its outer end is located within the side tread block, and the transverse steel sheets on the middle tread block and the side tread block are in an overall V-shaped structure.

[0013] In some embodiments, at least two transverse steel sheets are provided, and the distances between the longitudinal positions of the longitudinal steel sheets on the middle tread block and the tire center increase sequentially in the order from the tire inner side to the tire outer side.

[0014] In some embodiments, the transverse steel sheet is composed of a middle steel sheet in a continuous multi-fold segment structure in the middle and end steel sheets in a Z-shaped structure on both sides thereof, and the vertical distance between the upper and lower fold points of the end steel sheet is greater than the vertical distance between the upper and lower fold points of the middle steel sheet.

[0015] In some embodiments, the central longitudinal groove between each pair of middle tread blocks and the side longitudinal groove between each middle tread block and the side tread block are in an inclined straight-line structure.

[0016] In some embodiments, one transverse steel sheet is provided, and the intersection point of the longitudinal steel sheet and the transverse steel sheet is located at the connection of the middle steel sheet and the end steel sheet.

[0017] In some embodiments, two transverse steel sheets are provided, and the intersection points of the longitudinal steel sheets outside the two transverse steel sheets and the transverse steel sheets are located at the connection of the middle steel sheet and the end steel sheet, and the intersection points of the longitudinal steel sheets between the two transverse steel sheets and the transverse steel sheets are located at the middle of the middle steel sheet.

[0018] In some embodiments, the longitudinal misalignment distance between the pair of middle tread blocks is equal to the distance between the two transverse steel sheets.

[0019] A four-season light truck tire includes: the tire tread as described in any one of the above embodiments.

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] The central tread blocks and the side tread blocks adopt different quadrilateral structural designs and are combined and arranged in a staggered and centrosymmetric manner respectively. This arrangement can form multi-angle contact surfaces on the tread, thereby providing multi-directional frictional forces under different driving conditions (such as acceleration, braking, and steering), effectively increasing the tire's ground contact area, and at the same time achieving uniform pressure distribution to ensure the tire's grip and handling performance on dry roads. Compared with the tread blocks arranged in a straight line or in a single direction used in traditional light truck tires, this design can provide better performance under various road conditions.

[0022] Each tread block is provided with wavy fine lines, which can increase the edge effect of the tread on slightly icy and snowy roads. When the tire contacts the icy and snowy road surface, the wavy fine lines form tiny "anchor" points through multi-point contact, enhancing the tire's grip. This design is especially suitable for slightly snow-covered or icy road conditions, ensuring that the tire can still maintain excellent handling performance in low-temperature environments. In addition, the micro transverse grooves and the wavy fine lines work together to provide additional drainage and snow removal capabilities. At the same time, considering the different forces on the central and side parts of the tread, corresponding longitudinal steel sheets are set on the central tread blocks to adjust the rigidity strength in the middle, so as to provide driving comfort, and at the same time, the staggered arrangement method is used to further improve the friction performance.

[0023] Both the central longitudinal groove and the side longitudinal groove between adjacent tread blocks are designed with an inclined structure. The main function of these grooves is to prevent mud, snow, or stones from staying on the tread during driving. Through the rolling of the tire, these sundries can be automatically discharged, ensuring that the tread remains clean, and thus ensuring that the functionality of the tread will not be damaged by external factors. This self-cleaning design is especially suitable for muddy or gravelly roads, reducing tire maintenance requirements and extending service life. At the same time, a total of 3 longitudinal grooves are formed. These grooves are distributed along the tread, forming a deep channel penetrating the tread, enabling it to efficiently drain water on wet roads, thereby reducing the hydroplaning phenomenon. And at the same time, the design of the inclined angle is used to consider the natural drainage path of the water flow in parallel, so as to quickly guide the water flow away from the tread contact area, ensuring good contact between the tire and the road surface and improving driving stability.

[0030] A tire tread pattern, comprising:

[0031] A pair of middle tread blocks 3, which are arranged on both sides of the central longitudinal groove 1 on the tread surface in a left-right offset manner, and are provided with multiple groups along the movement direction of the tire;

[0032] A pair of side tread blocks 4, which are arranged on both sides of the central longitudinal groove 1 on the tread surface in a centrosymmetric manner, and are located outside a pair of middle tread blocks 3, and are provided with multiple groups along the movement direction of the tire;

[0033] The central tread blocks 3 and the side tread blocks 4 are arranged in two symmetrical ways, so that their distribution is more reasonable. It can not only form a multi-angle distribution method to improve the friction performance, but also make the overall force on the tread surface uniform, and then have better grip, handling and comfort on dry roads.

[0034] The transverse steel sheets 7 are in a multi-folded structure and are horizontally arranged through each central tread block 3 and semi-penetrated through each side tread block 4.

[0035] The longitudinal steel sheets 8 are in a straight-line segment structure and longitudinally penetrate through each area after the transverse steel sheets 7 divide the central tread blocks 3, and the longitudinal steel sheets 8 in each area are not collinear.

[0036] The multi-folded structure of the transverse steel sheets 7 can form tiny "anchor" points through its multiple folding points during the force application process, thereby increasing the grip of the tire. In slightly snowy or icy road conditions, it can effectively ensure that it still has excellent handling performance.

[0037] The transverse steel sheets 7 on the central tread blocks 3 adopt a through-structure design and cooperate with the longitudinal steel sheets 8 to further divide the tread blocks, thereby adjusting the rigidity strength of the central tread blocks 3 to make them more comfortable. Moreover, the longitudinal steel sheets 8 can also effectively cut the water film and improve the braking ability under wet roads.

[0038] The side tread blocks 4 adopt a semi-penetrated structure design instead of a fully penetrated structure design, mainly to ensure the support force strength of the side tread blocks during the vehicle turning process. Specifically, the inner end of the transverse steel sheet 7 on the side tread block 4 is connected to the side longitudinal groove 2 between the central tread block 3 and the side tread block 4, and its outer end is located inside the side tread block 4, and the transverse steel sheets 7 on the central tread block 3 and the side tread block 4 are in an overall V-shaped structure.

[0039] In some embodiments, the central transverse groove 5 between the adjacent upper and lower central tread blocks 3 is in a wavy structure with an upper opening and a lower opening; the side transverse groove 6 between the adjacent upper and lower side tread blocks 4 is in an arc-shaped structure. Through the overall approximate streamlined structure, it is convenient for the rapid discharge of water flow. At the same time, the central transverse groove 5 adopts a similar wavy structure, which also realizes the occlusion between the adjacent upper and lower central tread blocks 3, and is more conducive to the internal self-cleaning function during the turning force application process, and discharges sediment and stones by extrusion.

[0040] In some embodiments, there are at least 2 transverse steel sheets 7, and the distances between the longitudinal positions of the longitudinal steel sheets 8 on the central tread blocks 3 and the center of the tread surface increase sequentially in the order from the inside of the tire to the outside of the tire.

[0041] The above setting method adopts a uniformly distributed structural form. Among them, two transverse steel sheets 7 trisect the middle tread block 3. At the same time, as Figure 1 shown, the position of each longitudinal steel sheet 8 will change in a progressive manner, so that the overall performance of the tire is further improved accordingly.

[0042] Specifically, the transverse steel sheet 7 is composed of a middle steel sheet 9 located in the middle with a continuous multi-folded structure and end steel sheets 10 located on both sides thereof with a Z-shaped structure. And the vertical distance between the upper and lower folding points of the end steel sheet 10 is greater than the vertical distance between the upper and lower folding points of the middle steel sheet 9.

[0043] Due to the corresponding transverse grooves and longitudinal grooves provided on the outside of the middle tread block 3, the deformation space is relatively large. Therefore, the width dimension or the deformation range of the end steel sheet 10 itself is larger to reduce the risk of tread block tearing, while the width dimension or the deformation range in the middle is smaller to ensure the strength of the middle part.

[0044] In some embodiments, the central longitudinal groove 1 located between each pair of middle tread blocks 3 and the side longitudinal groove 2 located between each middle tread block 3 and the side tread block 4 are in an inclined straight-line structure. As Figure 1 shown, the side longitudinal groove 2 (left side), the central longitudinal groove 1 (middle part), and the side longitudinal groove 2 (right side) are all in a continuous broken-line structure as a whole and are arranged in a staggered manner. Furthermore, while ensuring the drainage performance, corresponding friction is provided to improve its controllability.

[0045] In some embodiments, there is 1 transverse steel sheet 7, and the intersection point of the longitudinal steel sheet 8 and the transverse steel sheet 7 is located at the connection between the middle steel sheet 9 and the end steel sheet 10.

[0046] In some embodiments, there are 2 transverse steel sheets 7. The intersection point of the longitudinal steel sheet 8 located outside the 2 transverse steel sheets 7 and the transverse steel sheet 7 is located at the connection between the middle steel sheet 9 and the end steel sheet 10, and the intersection point of the longitudinal steel sheet 8 located between the 2 transverse steel sheets and the transverse steel sheet 7 is located at the middle of the middle steel sheet 9. Further, the longitudinal misalignment distance between a pair of middle tread blocks 3 is equal to the distance between the two transverse steel sheets 7.

[0047] For the above two implementation methods, the setting of the longitudinal steel sheet 8 is adjusted respectively according to the number of the transverse steel sheets 7. Preferably, as Figure 1 shown, in the structure design with 2 transverse steel sheets 7, its comprehensive performance index is stronger.

[0048] A four-season light truck tire includes: the tire tread as in any one of the above embodiments.

[0049] Although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present utility model.
