The invention discloses a low-noise pneumatic tire tread pattern, which is provided with longitudinal grooves and resonators arranged on a grounding tread, wherein the resonators are arranged on the same sides of the longitudinal grooves in parallel, a resonance cavity in the resonator is communicated with the longitudinal groove through a neck part, a partition plate is arranged in the resonancecavity and divides the resonance cavity into a left side channel and a right side channel, the lengths of partition plates arranged between the adjacent resonators are different, and/or the widths ofthe right side channels arranged between the adjacent resonators are different, so that noise elimination frequency bands of the adjacent resonators are partially overlapped. Under the condition thatthe size of the cavity is not changed, the silencing frequency is migrated to low frequency or high frequency, and a good broadband silencing effect can be achieved.
本发明公开了一种低噪声充气轮胎胎面花纹,有设置在接地胎面上的纵沟和共鸣器,各共鸣器并联布置在纵沟的同一侧,共鸣器中共鸣腔体通过颈部与纵沟相连通,在共鸣腔体内设置隔板,将共鸣腔体分隔为左侧通道和右侧通道,设置相邻共鸣器之间的隔板长度存在有差异,和/或设置相邻共鸣器之间右侧通道宽度存在有差异,使相邻共鸣器的消声频带存在部分重叠。实现在不改变腔体尺寸的情况下,将消声频率向低频或高频迁移,能够实现很好的宽频消声效果。
