The wheel silencing device comprises a shell and a silencing cavity, a silencing opening is formed in the shell, the silencing cavity is formed in the shell, one end of the silencing cavity is communicated with the silencing opening, and the other end of the silencing cavity is closed; wherein at least one pair of silencing units are adjacently arranged, the silencing openings of the pair of silencing units are oppositely arranged, and the silencing cavities of the adjacent silencing units respectively adopt different resonance frequencies. Therefore, the wheel silencing device adopts a distribution mode that the double cavities are connected in parallel and then sequentially connected in series, noise can be uniformly reduced step by step, the length of the silencing pipe section and the length of the balance pipe section can be conveniently designed, and the balance of tires can be effectively guaranteed.
本发明公开了一种车轮消声装置及消声车轮,包括壳体和消声腔,其中,所述壳体上设有消声口,所述消声腔设于所述壳体内,所述消声腔的一端与所述消声口连通,另一端呈封闭状;其中,至少一对所述消声单元相邻设置,且该对所述消声单元的所述消声口相对设置,相邻所述消声单元的消声腔分别采用不同的共振频率。由此,本发明中的车轮消声装置采用双腔并联再依次串联的分布方式,不仅能均匀的逐级降噪,方便设计消声管段与平衡管段的长度,还能够有效的保证轮胎的平衡。
