The invention discloses a noise eliminating device for a pneumatic tire. A resonator is arranged in an annular tire cavity formed by a tire and a rim; the resonator is formed by arranging a plurality of arc-shaped tube cavities in parallel; a baffle plate is arranged in each pipe cavity, each pipe cavity is divided into a front section and a rear section by the baffle plate, one section is a silencing pipe section which is a quarter-wave pipe with one open end and one closed end, and the other section is a balance pipe section, and the balance pipe section is a cavity with two closed ends; tenons are arranged on the two sides of the resonator respectively, and the resonator is installed on the rim through the tenons. The noise eliminating device is simple in structure and can effectively realize broadband noise reduction.

    本发明公开了一种充气轮胎噪音消声装置,在由轮胎和轮辋构成的环形轮胎空腔中设置共振器;所述共振器是由数个呈圆弧形的管腔并联排布构成;在各管腔中各设置一道挡板,由所述挡板将管腔分为前后两段,一段是消声管段,所述消声管段是一端开口一端封闭的四分之一波长管;另一段是平衡管段,所述平衡管段为两端封闭的腔体;在所述共振器的两侧分别设置有凸榫,利用所述凸榫将共振器安装轮辋上。本发明结构简单,能够有效实现宽频降噪。
