Description

Technical Field

[0001] The invention relates to the field of tires, and in particular to a tire consisting of a crown pattern block and the pattern block. Background Art

[0002] With the popularity of high-horsepower tractors, the wear rate of drive wheel tires has significantly accelerated, resulting in a significant reduction in the mileage life of tires. At the same time, due to the increasing economic pressure in the freight industry, customers are paying more and more attention to the fuel consumption of the whole vehicle, so fuel-efficient tires are becoming more popular. To meet these challenges, we have developed a tire composed of crown blocks and tread blocks, aiming to meet customers' needs for high mileage and low rolling resistance fuel-saving performance, in order to solve the current technical problems in the market.

[0003] At present, the technical status of driving wheel has the following problems: (1) The pattern design generally adopts large and small block structures. Although it provides strong driving force, it leads to higher fuel consumption of the whole vehicle; (2) There are many grooves on the pattern surface and the pattern saturation is low, which cannot meet customers' expectations for tire mileage life.

[0004] In response to the needs of customers with high-horsepower tractors, we have developed a tire composed of crown tread blocks and tread blocks. The tire pattern design fully considers the characteristics of fast wear of the driving wheel position. By optimizing the design of the tread blocks and grooves and combining it with a special steel sheet structure, the tire has higher wear resistance while ensuring fuel saving and low rolling resistance performance, thereby extending the service life of the tire and helping customers reduce the cost of use. Summary of the invention

[0005] The purpose of the present invention is to provide a tire composed of a crown tread block and a tread block, which solves the problems of fast wear and high fuel consumption of the driving wheel tires of high-horsepower tractors by optimizing the design of the tread blocks, grooves and steel sheets, while meeting the customer's needs for low rolling resistance, fuel-saving performance and high mileage wear resistance, helping customers reduce their use costs.

[0006] The present invention adopts the following technical solution: A tread crown pattern block, the tread crown pattern block is composed of a heptagon ABCDEFG, the heptagon ABCDEFG includes a rectangle DEFG, one side of the rectangle DEFG is a parallelogram, and the other side of the parallelogram ACDG is an obtuse triangle ABC.

[0007] The surface of the rectangular DEFG is provided with knurling.

[0008] The thickness of the crown pattern block is 20-22 mm.

[0009] A tread crown pattern band, the tread crown pattern band comprises two single tread crown pattern bands, wherein the first single tread crown pattern band is arranged at intervals by the tread crown pattern block without knurling as claimed in claim 1 and the tread crown pattern block with knurling as claimed in claim 2, the interval of the interval arrangement is a groove formed by a 2D steel sheet arranged between the tread crown pattern block without knurling as claimed in claim 1 and the tread crown pattern block with knurling as claimed in claim 2, the second single tread crown pattern band is arranged centrally symmetrically with the first single tread crown pattern band, and a pattern groove is arranged between the first single tread crown pattern band and the second single tread crown pattern band.

[0010] The grooves provided on the first single tread crown pattern ring band are staggered with the grooves provided on the second single tread crown pattern ring band.

[0011] A tread crown pattern comprises two tread crown pattern ring bands, the tread crown pattern ring bands are centrally symmetrical, and a pattern groove is arranged between the two tread crown pattern ring bands.

[0012] A tread pattern, comprising a crown pattern and a shoulder pattern, wherein the shoulder pattern is a one-piece structure and has a protruding continuous obtuse triangle MNR on the inner side, the obtuse triangle corresponding to the obtuse triangle ABC in the first single crown pattern ring band described in claim 4 or claim 5; a pattern groove is arranged between the shoulder pattern and the first single crown pattern ring band described in claim 4 or claim 5.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are: 1. The special shape of the crown pattern blocks increases the contact area between the tire and the ground, which not only improves the grip but also enhances the driving performance. At the same time, the rolling pattern can form additional drainage channels when the tire contacts the ground and break the continuity of the tire surface, thereby reducing the overall noise level.

[0014] 2. The crown pattern sets grooves at specific positions. Due to the adjustment of the grooves, the tread blocks at different positions take turns to bear the main pressure, avoiding rapid wear of local tread blocks due to excessive force; at the same time, the grooves provide an effective channel for heat dissipation, improving the heat dissipation performance of the tire.

[0015] 3. The shoulder pattern adopts a full-circle continuous pattern block design, which significantly improves the pattern saturation and thus extends the tire's mileage.

[0016] In summary, the tire composed of a crown tread block and a tread block provided by the present invention improves tire heat dissipation, reduces rolling resistance, enhances grip and drivability, while taking into account high mileage wear resistance, providing customers with a more economical and reliable tire solution.

[0026] Among them, the length EF of rectangle DEFG is 30 mm, or 32 mm, or any length between 30-32 mm, and the width DE is 6 mm, or 7 mm, or any value between 6-7 mm; the base AC of parallelogram ACDG is 30 mm, or 32 mm, or any value between 30-32 mm, and the height OD is 16 mm, or 17 mm, or any value between 16-17 mm; the base AC of obtuse triangle ABC is 30 mm, or 32 mm, or any value between 30-32 mm, and the height BP is 3 mm, or 4 mm, or any value between 3-4 mm.

[0027] The thickness of the crown pattern block 301 is 20 mm, may be 22 mm, or any value between 20 and 22 mm.

[0028] like Figure 2 As shown, a shoulder pattern section, the shoulder pattern section 101 is composed of a pentagon KLMNR, and the pentagon KLMNR includes a rectangle KLMR and an obtuse triangle MNR; wherein, the length ML of the rectangle KLMR is 38 mm, or 40 mm, or any length between 38 and 40 mm, and the width DE is 30 mm, or 32 mm, or any value between 30 and 32 mm; the base MR of the obtuse triangle MNR is 38 mm, or 40 mm, or any length between 38 and 40 mm, and the height NQ is 1 mm, or 5 mm, or any value between 1 and 5 mm.

[0029] See also Figure 3 , a schematic structural diagram of a tire tread pattern formed by the above-mentioned pattern blocks provided in the present invention.

[0030] A tread crown pattern belt, comprising two single tread crown pattern belts, wherein the first single tread crown pattern belt 3 is arranged alternately by a tread crown pattern block 301 with a knurling pattern and a tread crown pattern block 301 without a knurling pattern, such as Figure 4 , 5 As shown, the above-mentioned interval is a groove 6 formed by a 2D steel sheet between the crown pattern block 301 with knurling and the crown pattern block 301 without knurling, and the groove width W1 of the groove 6 is 0.5 mm, or 1.2 mm, or any value between 0.5-1.2 mm, and the groove depth L1 is 11 mm, or 13 mm, or any value between 11-13 mm.

[0031] The second single crown pattern band 4 is centrally symmetrically arranged with the first single crown pattern band 3, and a pattern groove 2 is arranged between the first single crown pattern band 3 and the second single crown pattern band 4; the grooves arranged in the first single crown pattern band 3 and the grooves arranged in the second single crown pattern band 4 are staggered; the crown pattern bands are provided with grooves at specific positions, and pattern blocks at different positions take the main pressure in turn due to the adjustment of the grooves, thereby avoiding rapid wear of local pattern blocks due to excessive stress; at the same time, the setting of the grooves provides an effective channel for heat dissipation, thereby improving the heat dissipation performance of the tire; in addition, the grooves 6 are staggered to ensure the overall grip stability of the tire, so that the stress on various parts of the tire during driving is more uniform, thereby effectively extending the overall service life of the tire.

[0032] A tread crown pattern comprises two tread crown pattern ring bands, which are centrally symmetrical with each other, and a pattern groove 2 is arranged between the two tread crown pattern ring bands; the centrally symmetrical design of the two tread crown pattern ring bands enables each part of the tire to be more evenly stressed during driving, providing more stable longitudinal grip; at the same time, the arrangement of the pattern grooves avoids tire slippage caused by local water accumulation.

[0033] A tread pattern comprises a crown pattern and a shoulder pattern, wherein the shoulder pattern 1 is a whole-circle integral structure, and the inner side is a protruding continuous obtuse triangle MNR, the obtuse triangle MNR corresponds to the obtuse triangle ABC in the first single crown pattern ring band 3, that is, the obtuse triangle MNR in each shoulder pattern section 101 is nearly parallel to the obtuse triangle ABC in the first single crown pattern ring band 3 with respect to the transverse direction of the tire, and the obtuse triangle MNR is close in size to the obtuse triangle ABC; a pattern groove 2 is arranged between the shoulder pattern and the first single crown pattern ring band 3; the shoulder pattern adopts a whole-circle continuous pattern block design, which significantly improves the pattern saturation, thereby extending the service mileage of the tire.

[0034] The crown pattern blocks 301 and the shoulder pattern blocks 101 are both designed with an equal pitch, with a pitch number of 52. The equal pitch design allows the tire to be more evenly stressed when rolling, and the stress on each part is more balanced, further improving the durability of the tire.

[0035] In the embodiment of the present invention, the saturation of the tread pattern is 78%, which can improve the product mileage to a certain extent.

[0036] like Figure 3 , Figure 6As shown, the tread groove 2 adopts an alternating design of zigzag and straight types, and the width W2 of the zigzag groove 2 is 16 mm, or 17 mm, or any value between 16-17 mm, and the depth L2 of the zigzag groove is 20 mm, or 22 mm, or any value between 20-22 mm; the width W3 of the straight pattern groove is 2 mm, or 3 mm, or any value between 2-3 mm, and the depth L3 of the straight pattern groove is 16 mm, or 17 mm, or any value between 16-17 mm; the tread groove adopts an alternating design of zigzag and straight types, which increases the heat dissipation capacity of the tire and effectively reduces rolling resistance, thereby achieving a fuel-saving effect.

[0037] In summary, the tire composed of a crown tread block and a tread block provided by the present invention improves tire heat dissipation, reduces rolling resistance, enhances grip and drivability, while taking into account high mileage wear resistance, providing customers with a more economical and reliable tire solution.
