Description

Technical Field

[0001] This invention relates to the field of tire tread technology, and more specifically, to a shock-absorbing, self-cleaning all-wheel tire. Background Technology

[0002] Tire tread patterns, also known as tire tread designs, are molded or etched onto the outer tread of the tire. Their primary function is to improve tire performance and enhance aesthetics. The main types include: highway tread patterns, also known as ordinary tread patterns, suitable for paved roads; off-road tread patterns, also known as off-road tread patterns, suitable for unpaved conditions, with tread blocks occupying a large proportion of the total tire crown area; mixed tread patterns, also known as universal or all-purpose tread patterns, where the tread contact area accounts for approximately 65% ​​of the total tread surface area; and directional tread patterns, which have directional requirements and are herringbone or diagonal stripe patterns suitable for... Used for tires on construction machinery and agricultural tractors, it provides good traction and self-cleaning properties. When installing this type of tire, the apex of the herringbone or diagonal stripe must be aligned with the direction of travel, and the direction of travel must be marked with an arrow on the tire sidewall. If used in the opposite direction, mud will fill the grooves and lose traction. Suitable for driving on muddy and icy roads, the slush tread pattern is also known as the winter tread pattern. This is a block pattern with sharp-angled edges. This pattern has good anti-skid performance and can ensure safe driving on icy and muddy roads.

[0003] Tire tread patterns need to be selected according to different needs, but tire tread patterns are the most complex and difficult to design. There are many factors to consider. If the focus is too much on grip, it will generate more noise. If the focus is too much on water drainage, it will hinder the high-speed rotation of the tire. That is, if a certain performance is favored, other performances will be greatly lacking. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a shock-absorbing, self-cleaning all-wheel tire that simultaneously possesses good shock absorption, noise reduction, and anti-stone-trapping self-cleaning properties.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A shock-absorbing self-cleaning all-wheel tire, the tire tread pattern of which includes a central tread groove, a left tread groove, a right tread groove, a left rib, a right rib, a left shoulder rib, and a right shoulder rib extending along the tire circumference; the central tread groove is located in the center of the tread, and the left rib, left tread groove, and left shoulder rib are arranged sequentially from the inside to the outside on the left side of the central tread groove, and the right rib, right tread groove, and right shoulder rib are arranged sequentially from the inside to the outside on the right side of the central tread area;

[0007] The central tread groove, the left tread groove, and the right tread groove are zigzag-shaped along the tire circumference. On both sides of the bottom of the groove, there are strip-shaped protrusions along the tire circumference. The strip-shaped protrusions are higher than the bottom of the central groove. The strip-shaped protrusions can enhance the tire's ability to prevent stones from getting stuck and its self-cleaning performance.

[0008] The left and right ribs are zigzag annular strips with a zigzag angle of 140-160°. Between the two staggered inner corners of the annular strips, there are zigzag secondary grooves that connect the two patterned grooves. The zigzag secondary grooves are composed of flared sections at both ends and a connecting section in the middle. The flared sections connect the two patterned grooves respectively, and the connecting section connects the two flared sections.

Within each patterned block unit, a first zigzag shallow groove, a second zigzag shallow groove, and a third zigzag shallow groove are arranged longitudinally. The first and second zigzag shallow grooves are centrally symmetrically distributed, with zigzag angles of 130-150°.

The smooth section has a trench depth of 4 mm, while the deepened section has a chamfer with a chamfer radius of 5 mm. The trench depth of the deepened section gradually increases from 4 mm to 6 mm. The connection between the connecting section and the flared sections on both sides is stepped, with the upper and lower corners of the steps chamfered with a chamfer radius of 0.5 mm.

[0018] Preferably, the arc-shaped groove is a U-shape with unequal width, the bottom of the unequal width U-shape is rounded with a radius of 3-5mm; the inside of the arc-shaped groove is sloping with a slope height of 6-8mm, and the corner of the slope bottom is chamfered with a chamfer radius of 3-5mm; the inclined section of the arc-shaped groove is a U-shape with unequal width and a flat bottom, the two groove walls are inclined outward with an opening angle of 18-22°, and the two sides of the flat bottom are chamfered with a chamfer radius of 2-4mm.

[0019] Preferably, the grooves on the two sides of the U-shaped groove are rounded trapezoids with a radius of 0.5-1.5mm and an opening angle of 28-32°. The longitudinal section of the bottom of the U-shaped groove is an inclined U-shape, with the inner groove wall inclined outward at 13-17°.

[0020] Preferably, the decagonal patterned block has radium rays inside its middle part, and the radium rays have a serrated cross-section with a serration spacing of 0.5 mm and a depth of 0.5 mm.

[0021] The beneficial effects of this invention are as follows: the overall tread structure and layout of the tire provided by this invention can achieve the effect of shock absorption and noise reduction; the tread groove adopts a stepped groove bottom design, and protrusions are added on both sides of the groove wall to enhance the anti-stone-clamping ability of the main tread groove and the self-cleaning performance of the tread; the addition of transverse shallow grooves, i.e., zigzag secondary grooves, between the main grooves can enhance the drainage performance of the tread and improve the tire's grip on waterlogged and rough roads; the design of arc-shaped grooves and U-shaped grooves avoids stress concentration and can dissipate heat, thus extending the tire's service life.
