The invention relates to a tyre tread (1) for heavy vehicles and intended to improve its resistance to attack by stones. The tread (1) in a brand new state comprises at least one complex cut-out (5) comprising, along a bisector (Lm), an alternating arrangement of outer cavities (6) leading to the tread surface (2) and inner cavities (7) not leading to the tread surface (2), said at least one complex cut-out (5) comprising, along the bisector (Lm), an alternating arrangement of outer cavities (6) leading to the tread surface (2) and inner cavities (7) leading to the tread surface (2). Two consecutive cavities, respectively an outer cavity (6) and an inner cavity (7), are connected to each other by connecting channels (8) of non-zero length, the height (H11) of each outer cavity (6) being at least equal to half the height (H) of the complex cut (5), and the height (H3) of each connecting channel (8) being at most equal to one third of the height (H) of the complex cut (5).

    本发明涉及一种用于重型车辆并旨在改进其抗石头攻击性的轮胎胎面(1)。全新状态下的胎面(1)包括至少一个复杂切口(5),所述至少一个复杂切口(5)沿着等分线(Lm)包括外部空腔(6)和内部空腔(7)的交替排列,所述外部空腔(6)通向胎面表面(2),所述内部空腔(7)不通向胎面表面(2),分别为外部空腔(6)和内部空腔(7)的两个连续空腔通过非零的长度的连接通道(8)连接至彼此,每个外部空腔(6)的高度(H11)至少等于复杂切口(5)的高度(H)的一半,每个连接通道(8)的高度(H3)至多等于复杂切口(5)的高度(H)的三分之一。
