Description

Technical Field

[0001] The utility model belongs to the technical field of tire tread grooves, and in particular relates to a tire tread groove structure. Background Art

[0002] Tires are the devices that allow moving machinery, such as vehicles, to contact the ground and roll. Tires are primarily made of rubber. Firstly, the high friction between rubber and the ground provides high stability, significantly enhancing vehicle safety. Secondly, because rubber tires are elastic, they provide a cushion during driving, protecting both the vehicle and the operator.

[0003] In the industry, in order to further increase the friction between the tire and the ground and further effectively reduce the technical defects of the tire slipping with the ground during rotation, which leads to unstable vehicle driving, the industry often forms grooves on the tire to increase the friction between the tire and the ground through the grooves.

[0004] The grooves on the tread not only increase the friction with the ground, but also increase the grip between the tire and the ground. Therefore, the shape and size of the grooves are one of the key factors affecting the friction between the tire and the ground, and are also an important factor in determining the stability of the tire rolling on the ground.

[0005] Existing tires often feature a single curved or straight groove pattern on their treads. This type of groove pattern lacks stability, especially on slippery roads in rainy weather. It fails to prevent sideways or linear slip between the high-speed rotating tire and the ground. Consequently, in actual operation, as the tire's groove pattern gradually wears out, the risk of sideways or linear slip increases. Utility Model Content

[0006] Based on the above background, the purpose of the present utility model is to provide a tire tread groove structure.

[0007] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0008] A tire tread groove structure includes a plurality of circumferentially arranged first main grooves and a plurality of circumferentially arranged second main grooves on the tread;

[0009] A shallow tread groove is provided between the first main tread groove and the second main tread groove;

[0010] A plurality of circumferentially arranged first curved shallow pattern grooves are provided between the first main pattern grooves and the shallow pattern grooves;

[0011] The first curved shallow pattern groove is provided on the pattern block between the first main pattern groove and the shallow pattern groove;

[0012] A plurality of circumferentially arranged second curved shallow pattern grooves are provided between the shallow pattern groove and the second main pattern groove;

[0013] The second curved shallow pattern groove is provided on the pattern block between the second main pattern groove and the shallow pattern groove;

[0014] The first main pattern groove is in a straight line shape, and the second main pattern groove is in a broken line shape.

[0015] Preferably, the shallow tread groove is in the shape of a broken line.

[0016] Preferably, the groove wall cross-section of the shallow pattern groove is U-shaped.

[0017] Preferably, the groove wall cross-section of the second main pattern groove is U-shaped;

[0018] The bottom of the second main tread groove has a wavy circumferential shape, and the groove walls of the second main tread groove are staggered on both sides to form bosses. The center of the second main tread groove is provided with a plurality of platforms.

[0019] Preferably, first main pattern grooves are respectively provided at the edge portions of both sides of the tread;

[0020] The second main pattern groove is located between the first main pattern grooves on both sides.

[0021] Preferably, the shoulder areas on both sides of the tread are respectively provided with a plurality of circumferentially arranged circumferential pattern blocks.

[0022] Preferably, a plurality of shallow transverse pattern grooves are provided between the circumferential pattern block and the first main pattern groove.

[0023] Preferably, shoulder treads are provided on the sides of the circumferential pattern blocks;

[0024] The shoulder ridges are arranged at intervals on both sides of the tread.

[0025] Preferably, a plurality of rectangular platforms distributed at intervals are distributed in the central portion of the first main pattern groove.

[0026] The utility model has the following beneficial effects:

[0027] 1. The first main tread groove adopts a folded design (i.e., a folded shape), while the second main tread groove adopts a folded structure design. Specifically, the outer shape is arranged in a wavy shape. The purpose of this design is that the first main tread groove located at the edge prevents the tire from sliding. Specifically, when the tire tends to slide, the lateral friction between the first main tread groove and the ground is corrected, thereby correcting the tire's side slip force. At the same time, the second main tread groove with a folded structure design prevents the tire from sliding in a straight line. Especially in slippery conditions such as wet ground, once emergency braking is performed, the second main tread groove with a folded structure design can effectively increase friction with the ground, reduce the length of the side slip, and thus improve driving safety.

[0028] 2. The tire's tread is symmetrically arranged on both sides, with the second curved shallow groove as the primary tread pattern. The structure of first main groove - first curved shallow groove - shallow groove - second curved shallow groove - second main groove is symmetrically distributed on both sides of the tread. This complex groove pattern significantly increases friction between the tire and the ground, significantly enhancing the tire's resistance to sideslip and skid. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Example 1

[0036] like Figure 1 As shown, a tire tread groove structure includes a plurality of circumferentially arranged first main grooves 2 and a plurality of circumferentially arranged second main grooves 8 on the tread. Specifically, two first main grooves 2 are located on either side of the tread, one on the shoulder, while the second main groove 8 is located in the middle of the tread, between the two first main grooves 2. Furthermore, a plurality of spaced rectangular platforms 1 (equidistantly spaced) are distributed in the center of the first main groove 2. These platforms, like the platforms 7 described below, increase friction. Both main groove platforms can also serve as stone ejectors. During driving, these ejectors can be used to eject stones trapped in the groove or prevent large stones from becoming lodged in the groove and scratching the bottom of the tire groove.

[0037] In terms of shape, first, the first main pattern groove 2 adopts a straight line design (ie, a straight groove shape), while the second main pattern groove 8 adopts a folded structure design, specifically, the outer shape is arranged in a wavy shape.

[0038] This design primarily prevents the tire from slipping. Specifically, when the tire is about to slip, the lateral friction between the first main grooves 2 and the ground corrects the slipping force. Simultaneously, the second main grooves 8, with their zigzag design, prevent the tire from sliding linearly. This is especially true in slippery conditions, such as when the road is wet. In the event of an emergency brake call, the zigzag design effectively increases friction with the ground, reducing the length of the slip and thus improving driving safety.

[0039] The second main groove 8 has a U-shaped cross-section. Its bottom is wavy, with staggered ridges forming raised platforms on either side. Several circumferentially distributed V-shaped platforms 7 are located in the center of the second main groove. Specifically, these platforms 7 are rubber blocks of a given height.

[0040] In order to further increase the stability of the tire, a shallow pattern groove 5 is provided between the above-mentioned first main pattern groove 2 and the second main pattern groove 8 (specifically, a shallow pattern groove 5 is provided between the first main pattern groove 2 and the second main pattern groove 8 on the left side, and a shallow pattern groove 5 is provided between the first main pattern groove 2 and the second main pattern groove 8 on the right side).

[0041] The shape of the shallow pattern groove 5 is the same as that of the second main pattern groove 8, both of which are not folded and are wavy, and the cross-sectional shape of the groove wall of the shallow pattern groove 5 is U-shaped; the shallow pattern groove 5 is used to enhance the rigidity of the pattern block and the heat dissipation performance between the pattern blocks.

[0042] Therefore, the overall groove layout is: first main pattern groove 2 - shallow pattern groove 5 - second main pattern groove 8 - shallow pattern groove 5 - first main pattern groove 2.

[0043] At the same time, a plurality of circumferentially arranged first curved shallow grooves 4 are provided between the first main groove 2 and the shallow groove 5. A plurality of circumferentially arranged second curved shallow grooves 12 are provided between the shallow groove 5 and the second main groove 8. Thus, a structure of first main groove 2 - first curved shallow groove 4 - shallow groove 5 - second curved shallow groove 12 - second main groove 8 is formed.

[0044] Moreover, the tread is symmetrical with the second curved shallow groove 12, and the above-mentioned first main groove 2-first curved shallow groove 4-shallow groove 5-second curved shallow groove 12-second main groove 8 structure is symmetrically distributed on the left and right sides of the tread.

[0045] The shapes of the first curved shallow groove 4 and the second curved shallow groove 12 are S-shaped. The depths of the first curved shallow groove 4 and the second curved shallow groove 12 change regularly in sections, specifically, the depths change regularly with distance.

[0046] The first curved shallow groove 4 and the second curved shallow groove 12 are located at:

[0047] The first curved shallow groove 4 is provided on the tread block between the first main groove 2 and the shallow groove 5 , specifically on the left tread block 3 .

[0048] At the same time, a plurality of circumferentially arranged second curved shallow grooves 12 are provided between the shallow grooves 5 and the second main grooves 8. Similarly, the second curved shallow grooves 12 are provided on the tread block between the second main grooves 8 and the shallow grooves 5, specifically on the right tread block 6.

[0049] With the above structure, the tread is symmetrically distributed on both sides of the tread, with the second curved shallow groove 12 being the symmetrical structure. The structure of first main groove 2 - first curved shallow groove 4 - shallow groove 5 - second curved shallow groove 12 - second main groove 8 is symmetrically distributed on both sides of the tread. Therefore, the complex groove shape greatly improves the friction between the tire and the ground, and greatly enhances the tire's anti-skid and anti-slip capabilities.

[0050] Example 2

[0051] like Figure 1 As shown, this embodiment builds on the structure of Example 1. To further enhance the tire's sideslip resistance, several circumferentially arranged circumferential blocks 9 are provided on the shoulders of both sides of the tread. Several shallow transverse grooves 10 are located between the circumferential blocks 9 and the first main grooves 2. Each circumferential block is flanked by shoulder lugs 11 (with varying depths in a segmented, irregular pattern to maintain heat dissipation at the shoulder). The shoulder lugs 11 are spaced apart on both sides of the tread. These shallow transverse grooves 10 further enhance the tire's sideslip resistance.

[0052] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
