According to the Helmholtz silencing device for the vehicle and the rim, at least one silencing part is connected end to end to form a circular closed loop, and each silencing part comprises an arc-shaped bottom plate capable of being attached to the outer circumferential face of the hub and a Helmholtz resonator fixed to the arc-shaped bottom plate; a first connecting part and a second connecting part which can be spliced with each other are respectively arranged at two ends of the arc-shaped bottom plate in the length direction of the arc-shaped bottom plate. The Helmholtz silencing device for the vehicle is composed of at least one silencing part, the first connecting part and the second connecting part on the two sides of the arc-shaped bottom plate of the silencing part can be connected end to end to be spliced into a circular closed ring, and the circular closed ring is attached to the outer circumferential face of a wheel hub to form the annular silencing device. The Helmholtz resonators can be suitable for circular wheel hubs of various sizes, the Helmholtz resonators can be conveniently installed on hubs of various commercial wheels for use, and the number of the Helmholtz resonators on the hubs can be set according to actual requirements so as to meet the requirements of different vehicle types.

    本发明提供了一种车用亥姆霍兹消声装置及轮辋,由至少一个消声部首尾相接形成圆形闭环,消声部包括可与轮毂外圆周面贴合的弧形底板和固定于弧形底板上的亥姆霍兹共鸣器,弧形底板在其长度方向的两端分别设置有可相互拼接的第一连接部和第二连接部。本发明所提供的一种车用亥姆霍兹消声装置由至少一个消声部组成,可将消声部的弧形底板两侧的第一连接部和第二连接部首尾相接拼接成圆形闭环并贴合至车轮轮毂的外圆周面上形成环形的消声装置,可以适用于各种尺寸的圆形车轮轮毂,方便安装于各种商用车轮的轮毂上使用,并且可根据实际需求设置轮毂上亥姆霍兹共鸣器的数量以满足不同车型。
