Technical Field

[0001] This utility model relates to a fuel-efficient, high-mileage, low-rolling-resistance drive wheel, and more particularly to a tire tread pattern block and a fuel-efficient, high-mileage, low-rolling-resistance drive wheel pattern. Background Technology

[0002] As the only part of a vehicle in contact with the ground, the rolling resistance of tires directly affects fuel consumption. The tire industry has also proposed developing "low-noise, low-rolling-resistance, and high-wear-resistance" green tires. With the increasing severity of the energy crisis and environmental pollution, research into high-mileage, low-fuel-consumption tires is imperative.

[0003] Practice has shown that, with the tire compound system remaining unchanged, the tire tread design is closely related to the tire rolling resistance.

[0004] In order to reduce fuel consumption and rolling resistance of the drive wheels and improve mileage, high-speed performance and straight-line driving ability, existing technologies use complex tire tread structures. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a tire tread pattern block and a fuel-efficient, high-mileage, low-rolling-resistance drive wheel tread pattern. The tread block has a simple structure, with knurling connected to the transverse edges of the tread blocks at both ends via strip-shaped grooves I, thereby improving grip, enhancing aesthetics, improving straight-line driving ability, providing good high-speed performance, and offering excellent heat dissipation and low rolling resistance. This, in turn, increases tire mileage and reduces rolling resistance and fuel consumption.

[0006] The technical solution of this utility model is as follows: a tire tread pattern block, wherein the longitudinal edge of the pattern block is arranged parallel to the circumferential direction of the tire, and the center of the pattern block is provided with knurling, and the knurling is connected to the transverse edge of the pattern block through a strip-shaped sipe I.

[0007] The knurling includes a closed structure formed by connecting the two ends of the groove II. The closed structure has three or more strip-shaped grooves inside, which are arranged in parallel and whose outer ends are connected to the closed structure.

[0008] The spacing between adjacent strip grooves is 8.3mm-8.5mm; the width of the strip groove is 0.5-0.7mm.

[0009] The strip-shaped grooves are set parallel to the transverse edge of the patterned block; the angle between the strip-shaped groove I and the longitudinal edge of the patterned block is 1°-2.5°.

[0010] A fuel-efficient, high-mileage, low-rolling-resistance drive wheel tread pattern includes tread blocks and tread grooves arranged along the tire circumference. The tread blocks are the tire tread blocks described above. A transverse groove is formed between adjacent tread blocks in the same circumference. The tread blocks include crown tread blocks and shoulder tread blocks. A central tread groove is located at the center of the tire's transverse direction, and shoulder tread blocks are located on both sides.

[0011] The tread pattern blocks are parallelograms, with one pair of opposite corners chamfered; the inner side of the shoulder tread pattern blocks has shoulder tread grooves, and the two corners of the shoulder tread blocks closest to the shoulder tread grooves are chamfered.

[0012] The tread blocks on the same side of the drive wheel's center axis have the same chamfer; the tread blocks on the same side of the center axis are misaligned in the tire circumferential direction by half the length of the tread block.

[0013] The drive wheel pattern is formed by mirroring the pattern on the left side of the central axis to create the pattern on the right side, and then the patterns on the left and right sides are longitudinally misaligned in the direction of the central axis.

[0014] The drive wheel tread pattern features an open shoulder.

[0015] Adjacent tread blocks in the same circumferential direction are connected by connecting rib I, and adjacent shoulder tread blocks in the same circumferential direction are connected by connecting rib II, which extends toward the tire side.

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings and specific embodiments. It should be understood that the preferred embodiments described herein are only for illustration and explanation of this utility model and should not be construed as limiting the scope of protection of this utility model. Those skilled in the art can make some non-essential improvements and adjustments based on the content of this utility model below. In this utility model, unless otherwise expressly specified and limited, the technical terms used in this application should have the ordinary meaning understood by those skilled in the art.

[0024] like Figures 1-3 As shown, a tire tread pattern block is provided. The longitudinal edge 14 of the pattern block 1 is arranged parallel to the circumference of the tire. The center of the pattern block is provided with knurling 2, and the knurling 2 is connected to the transverse edge 15 of the pattern block through a strip-shaped sipe I3.

[0025] The knurling 2 is connected to the transverse edges 15 of the patterned blocks at both ends through the strip-shaped grooves I3, which improves grip, looks beautiful and stylish, is beneficial to the vehicle's straight-line driving ability, has good high-speed performance, and also has good heat dissipation and low rolling resistance.

[0026] The knurling 2 includes a closed structure formed by the connection of two end-to-end grooves II 20. The closed structure contains three or more parallel strip-shaped grooves 21, with their outer ends connected to the closed structure. The spacing between adjacent strip-shaped grooves is 8.3-8.5 mm; the width of each groove is 0.5-0.7 mm, preferably 0.6 mm. This design improves appearance, enhances wear resistance, and reduces abnormal wear.

[0027] The strip-shaped grooves 21 are set parallel to the transverse edge 15 of the patterned block. In this way, the knurling acts as a transverse groove, which has a heat dissipation function and provides good slip performance.

[0028] The strip-shaped groove I3 is not parallel to the longitudinal edge 14 of the patterned block, and the included angle between the strip-shaped groove I3 and the longitudinal edge 14 of the patterned block is 1°-2.5°, preferably 2°. This results in more even wear during operation.

[0029] A fuel-efficient, high-mileage, low-rolling-resistance drive wheel tread pattern includes tread blocks 1 arranged along the tire circumference and tread grooves arranged along the tire circumference. The tread blocks are the tire tread blocks 1 described above. A transverse groove is formed between adjacent tread blocks in the same circumference. The tread blocks include crown tread blocks and shoulder tread blocks 13. There is a central tread groove at the center of the tire's transverse direction and shoulder tread blocks on both sides.

[0030] The inner side of the tire shoulder tread block is provided with a tire shoulder tread groove 42, and a stone-discharging platform 5 is provided in the tire shoulder tread groove. The stone-discharging platform is connected by a reinforcing rib Ⅲ50.

[0031] The tire tread blocks are parallelograms, with one pair of opposite corners chamfered. This parallelogram design with chamfers provides stronger driving force compared to a regular quadrilateral design.

[0032] The chamfers of the tread blocks on the same side of the center axis are identical. The circumferential misalignment length of the tread blocks on the same side of the center axis is half the length of the tread block.

[0033] The two corners of the shoulder tread block 13 near the shoulder tread groove 42 are chamfered to reduce deformed wear and prevent tread blocks from falling off.

[0034] The chamfer has a horizontal length of 3.8mm and a vertical length of 3mm.

[0035] The tire tread pattern includes a center tread block 11 and intermediate tread blocks 12. In the lateral direction of the tire, from the center outwards, they are: center tread groove 40, center tread block 11, intermediate tread groove 41, intermediate tread block 12, shoulder tread groove 42, and shoulder tread block 13. The tread grooves include center tread groove 40, intermediate tread groove 41, and shoulder tread groove 42.

[0036] The tread pattern of the drive wheel is formed by mirroring the pattern on the left side of the central axis to create the pattern on the right side, and then longitudinally offsetting the patterns on both sides along the central axis. The tread pattern of this application is a unidirectional pattern, which has advantages such as good handling performance, low rolling resistance, strong grip, and excellent water drainage. Simultaneously, the staggered alignment of the patterns on both sides, along with the staggered arrangement of the lateral grooves, improves ground contact continuity and enhances the driving performance of the tread.

[0037] The patterns on the left and right sides are longitudinally offset along the central axis, with an offset length of 28-33mm, preferably 31mm.

[0038] The tire shoulder of the drive wheel pattern in this application is an open shoulder to maximize heat dissipation.

[0039] Adjacent tread blocks in the same circumferential direction are connected by connecting rib I6, and adjacent shoulder tread blocks in the same circumferential direction are connected by connecting rib II7, which extends towards the tire sidewall. This enhances the overall rigidity of the tread pattern and reduces its deformation, thereby reducing the tire's rolling resistance to some extent.

[0040] The drive wheel tread pattern of this application has an open shoulder, with connecting rib II7 extending towards the tire sidewall. This can reduce the heat generation of the shoulder, improve the tire's water drainage and driving performance, enhance the overall rigidity of the tire shoulder tread pattern, and reduce the deformation of the tread blocks, thereby reducing the tire's rolling resistance.

[0041] The depth of the connecting rib I6 is 0.76-0.80 times the total depth of the pattern groove, preferably 0.78 times. This can reduce the rolling resistance in the early stage of pattern use and ensure the driving ability in the later stage of pattern use.

[0042] Furthermore, the tread grooves are straight. The width of the center tread groove 40 and the intermediate tread groove 41 is narrower than the width of the shoulder tread groove 42. The center tread groove 40 and the intermediate tread groove 41 are designed to be full depth (22 mm), while the shoulder tread groove is designed to be half depth (11 mm). Narrowing the width of the center and intermediate tread grooves effectively reduces the tire's rolling resistance while maintaining tire traction and water drainage performance. Lowering the rolling resistance effectively increases the product's mileage. The tread groove depth is the total tread groove depth. Narrowing the width of the center tread groove 40 and the intermediate tread groove 41 increases the tread pattern's saturation. Increasing the tread groove depth ensures both tire traction and water drainage performance.

[0043] The center tread groove 40 and the intermediate tread groove 41 have the same width, and the ratio of the width of the center tread groove 40 or the intermediate tread groove 41 to the width of the shoulder tread groove 42 is 3:5. The width of the center tread groove and the intermediate tread groove can be 5.5-6.5mm, preferably 6mm.

[0044] The tread pattern has the same pitch and is arranged in a regular pattern to reduce tread noise.
