The invention provides a tire tread structure. A plurality of longitudinal grooves of the tire tread structure extend in the circumferential direction of a tire, and the plurality of longitudinal grooves divide a tire tread into tire shoulder pattern parts and middle pattern parts located between the two tire shoulder pattern parts; the first grooves are formed in the middle pattern part, the two ends of each first groove communicate with the two longitudinal grooves adjacent to the middle pattern part correspondingly, and the multiple first grooves are formed in the circumferential direction of the tire at intervals so as to divide the middle pattern part into multiple middle pattern blocks; wherein in the circumferential direction of the tire, at least part of the first groove protrudes towards the first direction and forms an arc-shaped section, so that one middle pattern block adjacent to the first groove forms a matched protrusion, the other middle pattern block adjacent to the first groove forms a matched concave part, and when the middle pattern part elastically deforms, the arc-shaped section is matched with the matched protrusion. And at least part of the outer peripheral surface of the matching bulge and the inner wall of the matching concave part are limited and stopped. The problem that in the prior art, a middle axle trailer is poor in driving stability is effectively solved.
本发明提供了一种轮胎胎面结构。轮胎胎面结构的多个纵向沟槽均沿轮胎的周向延伸,多个纵向沟槽将胎面分隔为胎肩花纹部和位于两个胎肩花纹部之间的中间花纹部;第一沟槽设置在中间花纹部上,其两端分别和与中间花纹部相邻的两个纵向沟槽连通,多个第一沟槽沿轮胎的周向间隔设置,以将中间花纹部分隔为多个中间花纹块;其中,沿轮胎的周向,第一沟槽的至少部分朝向第一方向凸出并形成弧状段,以使与第一沟槽相邻的一个中间花纹块形成配合凸起、与第一沟槽相邻的另一个中间花纹块形成配合凹部,在中间花纹部发生弹性形变时,配合凸起的至少部分外周面与配合凹部内壁限位止挡。本发明有效地解决了现有技术中的中置轴挂车的行驶稳定性较差的问题。
