Embodiment Construction

[0015] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0016] like image 3 , Figure 4 Shown is a tire tread zipper zigzag groove, the bottom of the groove is an arc-shaped annular bottom surface 1, and the upper two annular sides of the arc-shaped bottom surface are the first annular slope 2 and the first annular slope 2 respectively. It is inclined outward from the bottom, and the two first annular slopes 2 are respectively provided with annular sawtooth strips 3 protruding from the first annular slope 2, and the annular sawtooth strips 3 are arranged at intervals by bosses 4 and grooves 5 to form a ring structure, The bosses 4 and the grooves 5 on the two ring-shaped zigzag strips 3 are arranged in a zipper-like misalignment; the side of the boss 4 and the annular bottom surface 1 obliquely is a second slope 6, and the second slope 6 is composed of The bottom is inclined to the...

Abstract

The invention relates to the field of tire manufacturing, in particular to a tire tread groove and a wide base tire using same. A groove of a tire tread zipper saw-tooth type groove adopts a saw-toothzipper design; the left side and the right side of an annular saw-tooth strip are staggered; the edge part of each boss has a certain gradient to stop stones against entering; the whole boss is madecomparatively larger and obviously protrudes; by using the repeated zipper type design, the stones are hard to enter the groove; as the groove wall adopts a design with a certain gradient and the twosides of the boss also have certain cutting pitches, four surfaces of the groove are all inclined walls; and a three-dimensional funnel type design is adopted to remove stones. The tire tread zipper saw-tooth type groove has the advantages that an obvious stone removing effect on the wide base tire during running on roads is obtained, the tire groove bottom cracks are greatly reduced and safety accidents are prevented.

Description

technical field [0001] The invention relates to the field of tire manufacturing, in particular to a tire tread groove and a wide-base tire using the groove. Background technique [0002] For tires, tire pattern not only plays an aesthetic role, but also has corresponding functions, such as affecting tire rolling noise, dry and wet grip, fuel consumption, stone drainage effect, etc. At present, international regulations on tire noise , wet slip and rolling resistance have made corresponding regulations and grade divisions, but functions such as stone discharge and drainage have not been further evaluated. The tire pattern is usually composed of longitudinal, transverse or combination of vertical and horizontal grooves. The wider grooves are generally designed as V-shaped or U-shaped with a certain depth, so as to ensure that the tire can maintain a good condition from the new tire to the pattern polishing process. Handling performance. Ordinary V-shaped or U-shaped grooves ...
