The invention relates to the field of tires, in particular to a tire capable of disturbing airflow and reducing noise, which comprises an inner pattern strip arranged in the middle of a tread and outer pattern strips arranged on two sides of the tread, and outer pattern grooves recessed towards the inner side of the tread are formed between the inner pattern strip and the outer pattern strips. The inner side pattern strips, the outer side pattern strips and the outer side pattern grooves extend in the circumferential direction of the tread and form a ring shape; the outer side pattern groove comprises a plurality of groove sections which are connected with one another, the joints of the upper groove section and the lower groove section are staggered with one another, so that a plurality of turbulent flow structures protruding towards the inner side of the groove are formed on the side wall of the outer side pattern groove, air flows through the turbulent flow structures and collides with the turbulent flow structures, the flowing direction is changed, and noise is reduced. The tire has the advantages that the pattern grooves on the outer side are in the barb-shaped zigzag shape, so that the noise of the tire can be reduced by disturbing the flowing characteristics of airflow in the pattern grooves.
本发明涉及轮胎领域,尤其是一种扰乱气流降低噪音的轮胎,包括设置在胎面中部的内侧花纹条和设置在胎面两侧的外侧花纹条,内侧花纹条和外侧花纹条之间形成有向胎面内侧凹陷的外侧花纹沟,内侧花纹条、外侧花纹条和外侧花纹沟各自沿着胎面的周向延伸并形成环形;外侧花纹沟包括若干段相互连接的沟槽段,上下两个沟槽段的连接处相互错位,使得外侧花纹沟的侧壁上形成有若干处向沟槽内侧凸出的扰流结构,空气流经扰流结构,与扰流结构碰撞,改变流动方向,降低噪音。本发明的优点是:外侧花纹沟具有倒刺型的曲折形状,可以通过扰乱气流在花纹沟内流动特性来降低轮胎的噪音。
