The noise elimination hub comprises a rim and a noise elimination assembly, the noise elimination assembly comprises at least two noise elimination units, the at least two noise elimination units are arranged in the circumferential direction of the rim, noise elimination cavities are formed in the noise elimination units, an opening is formed in one end of each noise elimination cavity, and the other end of each noise elimination cavity is in a closed shape; the silencing cavities of the silencing units adopt different resonant frequencies, each silencing cavity comprises a circumferential section and a bent section, and the circumferential section and the bent section are arranged in a bent mode; the space, occupied by the circumferential section, of the rim in the circumferential direction is shortened, so that more silencing units with different resonant frequencies are arranged under the condition that the total length of the silencing cavity is not affected, and the broadband noise reduction effect is truly achieved.
本发明公开了一种消声轮毂及车轮,包括轮辋和消声组件,所述消声组件包括至少两个消声单元,至少两个所述消声单元环绕所述轮辋的周向设置,所述消声单元内设有消声腔,所述消声腔的一端设有开口,另一端呈封闭状,若干所述消声单元的消声腔分别采用不同的共振频率,所述消声腔包括周向段和折弯段,所述周向段与所述折弯段之间弯折设置;本发明通过缩短周向段占用轮辋周向上的空间,从而在不影响消声腔总长度的情况下,布置更多的不同共振频率的消声单元,从而真正地实现宽频降噪的效果。
