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 requirements due to too small load weight, nor will they be restricted due to too large 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. Currently, 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] Details of one or more embodiments of the present utility model are set forth in the following drawings and description, so as 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 comprehensively considering various road conditions and climate conditions, a multifunctional tread pattern structure is designed, which has good grip, durability, and self-cleaning ability on dry, wet, icy, and muddy roads. Thus, it can not only meet the needs of year-round use, but also provide higher comfort and safety.

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

[0007] A pair of middle tread blocks, symmetrically arranged at the center and provided with multiple groups along the movement direction of the tire. A middle longitudinal groove is provided between each pair of the middle tread blocks; the pair of adjacent upper and lower middle tread blocks and the adjacent upper and lower middle longitudinal grooves are all arranged in a staggered manner;

[0008] A pair of side tread blocks, arranged on both sides of each pair of the middle tread blocks. A side longitudinal groove is provided between each side tread block and each middle tread block; the adjacent upper and lower side longitudinal grooves are arranged in a staggered manner;

[0009] Transverse steel sheets, at least one section of which is serrated, and are respectively penetrated and semi-penetratedly arranged on the middle tread blocks and the side tread blocks;

[0010] Auxiliary steel sheets, serrated, and arranged at positions between two inflection points on the same side of the serrated part of the transverse steel sheets to form a polygonal structure.

[0011] In some embodiments, the transverse steel sheets on the middle tread blocks and the transverse steel sheets on the side tread blocks form an overall continuous Z-shaped structure.

[0012] In some embodiments, the middle transverse grooves between adjacent upper and lower middle tread blocks and the side transverse grooves between adjacent upper and lower side tread blocks form an overall continuous Z-shaped structure.

[0013] In some embodiments, the upper and lower sides of the middle tread block are in a V-shaped structure; the transverse steel sheet on the middle tread block is in an overall V-shaped structure.

[0014] In some embodiments, it further includes:

[0015] A middle side groove and an outer side groove, which are in an inwardly concave structure, and are respectively arranged alternately and offset on the edges of the middle tread block and the side tread block on both sides of the side longitudinal groove.

[0016] In some embodiments, there are two transverse steel sheets; the middle side groove is located between the two transverse steel sheets; the outer side groove is located outside the two transverse steel sheets; the middle side groove and the outer side groove are alternately arranged on adjacent upper and lower middle tread blocks and adjacent upper and lower side tread blocks, and the middle side groove and the outer side groove on the middle tread block are arranged offset from those on the side tread block.

[0017] In some embodiments, the transverse widths of adjacent upper and lower side tread blocks are inconsistent.

[0018] In some embodiments, the polygonal structure is a symmetric structure.

[0019] In some embodiments, the depth of the auxiliary steel sheet is less than the depth of the transverse steel sheet.

[0020] A four-season light truck tire, comprising: the tire tread as described in any one of the above embodiments.

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] By optimizing the distribution structure of the middle tread block and the side tread block, middle longitudinal grooves and side longitudinal grooves arranged offset are formed, providing multi-directional contact surfaces, enabling the tire to maintain stable grip under different direction forces (such as sharp turns and emergency braking), and the arrangement of the tread blocks effectively disperses the pressure when the tire contacts the ground, reducing local wear of the tread surface, thereby extending the service life of the tire.

[0023] Each tread block is internally provided with serrated transverse steel sheets, which are distributed along the tread block, and corresponding auxiliary steel sheets are arranged on the transverse steel sheets of the middle tread block to form tiny incisions in the shape of a polygon structure; the serrated structure can effectively increase the contact area of the edge of the tread block to improve the grip of the tire on a wet road surface and prevent the tire from slipping, especially performing more excellently on a wet road surface or muddy road conditions. In the case of an ice and snow road surface, at this time, the tiny incisions (polygon structure) play an additional biting role, especially on a road surface covered with ice and snow, which can increase the friction of the tread surface and reduce the possibility of the vehicle slipping, thereby improving the handling stability under ice and snow road conditions.

[0031] A tire tread pattern, comprising:

[0032] A pair of central tread blocks 3, symmetrically arranged at the center and provided with multiple groups along the moving direction of the tire. A central longitudinal groove 1 is provided between each pair of central tread blocks 3; the upper and lower adjacent pairs of central tread blocks 3 and the upper and lower adjacent central longitudinal grooves 1 are all arranged in a staggered manner.

[0033] A pair of side tread blocks 4, arranged on both sides of each pair of central tread blocks 3. A side longitudinal groove 2 is provided between each side tread block 4 and each central tread block 3; the upper and lower adjacent side longitudinal grooves 2 are arranged in a staggered manner.

[0034] Transverse steel sheets 5, at least one section of which is serrated, and are respectively arranged through and semi-through on the central tread blocks 3 and the side tread blocks 4.

[0035] Auxiliary steel sheets 6, which are serrated, and are arranged at the positions between two inflection points on the same side of the serrated part of the transverse steel sheets 5 to form a polygonal structure.

[0036] In some embodiments, the transverse steel sheets 5 on the central tread blocks 3 and the transverse steel sheets 5 on the side tread blocks 4 as a whole form a continuous Z-shaped structure. The central transverse grooves 9 between the upper and lower adjacent central tread blocks 3 and the side transverse grooves 10 between the upper and lower adjacent side tread blocks 4 as a whole form a continuous Z-shaped structure.

[0037] The overall structures of the steel sheets and the grooves adopt a continuous Z-shaped structure, which can not only effectively ensure good friction, but also make the force more evenly distributed due to the continuous structure design. Specifically, the upper and lower sides of the middle tread block 3 are in a V-shaped structure; the overall shape of the transverse steel sheet 5 located on the middle tread block 3 is in a V-shaped structure. This design has the following main functions: First, drainage performance: On a slippery road surface, the V-shaped grooves can effectively guide the water flow to quickly drain out of the tread, thereby reducing the hydroplaning phenomenon and ensuring the tire's grip on the slippery road surface. Second, snow grip: Under snowy conditions, the snow-compacting effect of the V-shaped grooves is significant. By increasing the friction between the tread and the snow, the tire's grip ability is enhanced, thus improving the vehicle's handling and safety. Third, tread contact stability: This V-shaped design can provide a more stable tread contact surface, providing more reliable friction when the vehicle steers, accelerates, or brakes. The side transverse grooves 10 on both sides adopt a straight-line structure to ensure rapid drainage.

[0038] At the same time, due to the limitation of the above structural shape, the tread blocks on the tire tread form an approximately quadrilateral structural form and are arranged in a staggered pattern at a certain angle. This design has the following main functions: First, multi-directional grip: The approximately quadrilateral shape (V-shaped on the top and bottom) can provide a multi-directional contact surface through its geometric shape, enabling the tire to maintain stable grip under different directional forces (such as sharp turns and emergency braking). Second, uniform pressure distribution: The arrangement of the tread blocks effectively disperses the pressure when the tire contacts the ground, reducing local wear on the tread and thus extending the tire's service life. Third, enhanced straight-line driving stability: The approximately quadrilateral shape (V-shaped on the top and bottom) and the transverse steel sheet 5 (V-shaped) on the middle tread block 3 enhance the tire's stability during straight-line driving, reducing the vibration and side-slip risks of the vehicle during high-speed driving, and also improving the tire's durability.

[0039] Specifically, the polygonal structure is a symmetric structure. The depth of the auxiliary steel sheet 6 is less than the depth of the transverse steel sheet 5.

[0040] First of all, both the transverse steel sheet 5 and the auxiliary steel sheet 6 are designed in a serrated structure form. This design can effectively increase the contact area of the tread blocks, significantly enhancing the tire's grip on a slippery road surface. Thus, it can effectively prevent the tire from slipping, especially performing well on a slippery road surface or in muddy conditions.

[0041] The middle tread blocks 3 are separated by the auxiliary steel sheets 6 and the transverse steel sheets 5 to form tiny incisions in the shape of a polygon structure. The symmetrical structure has more balanced and stable force, and the depth of the auxiliary steel sheets 6 is less than that of the transverse steel sheets 5, which also prevents the tread blocks from being easily torn due to the same groove depth. Moreover, the above structure can also play an additional biting role in a low-temperature environment. Especially on a road covered with ice and snow, it can increase the friction of the tread surface and reduce the possibility of vehicle skidding, thereby improving the handling stability under ice and snow road conditions.

[0042] In some embodiments, it further includes:

[0043] The middle side grooves 7 and the outer side grooves 8, which are in the shape of an inwardly concave structure, are respectively and alternately arranged at the edges of the middle tread blocks 3 and the side tread blocks 4 on both sides of the side longitudinal grooves 2.

[0044] Specifically, as Figure 1 shown, there are two transverse steel sheets 5; the middle side grooves 7 are located between the two transverse steel sheets 5; the outer side grooves 8 are located outside the two transverse steel sheets 5; the middle side grooves 7 and the outer side grooves 8 are alternately arranged on the adjacent upper and lower middle tread blocks 3 and the adjacent upper and lower side tread blocks 4, and the middle side grooves 7 and the outer side grooves 8 on the middle tread blocks 3 are arranged in a staggered manner with the middle side grooves 7 and the outer side grooves 8 on the side tread blocks 4.

[0045] Through the staggered design, the biting of adjacent tread blocks is achieved during the tire's force application process, thereby playing a self-cleaning role. Among them, for the exclusion of mud and sand: during driving, these side grooves can automatically remove sundries such as mud and sand on the tread surface, keep the tread surface clean, and prevent the decrease in grip caused by the accumulation of sundries. For the exclusion of snow: when driving in the snow, the side groove design can also effectively discharge the snow on the tread surface, prevent the snow from blocking the grooves, and ensure the normal function of the tread surface under snow conditions. At the same time, the effect is stronger when combined with the aforementioned upper and lower staggered middle longitudinal grooves 1 and side longitudinal grooves 2.

[0046] In some embodiments, the transverse widths of the adjacent upper and lower side tread blocks 4 are inconsistent. The inconsistent setting of the transverse width is one to meet the need for the aforementioned staggered design of the side longitudinal grooves 2, and the other is to reduce the superposition of shoulder tread block noises and lower the noise level during vehicle driving, especially obvious when driving at high speed.

[0047] A four-season light truck tire includes: the tire tread pattern according to any one of the above embodiments.

[0048] 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 on 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 various embodiments of the present utility model.
