The invention discloses a sound absorption and noise reduction device for a wheel and the wheel with the sound absorption and noise reduction device. The sound absorption and noise reduction device for the wheel comprises a porous sound absorption base body and a plurality of sound absorption structures, wherein the plurality of sound absorption structures are arranged on the porous sound absorption base body, and each sound absorption structure is provided with a sound absorption inlet extending to the surface of the porous sound absorption base body; and each sound absorption structure comprises a convergence area and a sound absorption area, the convergence area is arranged in the porous sound absorption substrate and has the same cross section size, one end of the sound absorption area communicates with the other end of the convergence area to form the sound absorption inlet, and the cross section size is gradually increased when the sound absorption area extends from the convergence area to the surface direction of the porous sound absorption base body. According to the wheel sound absorption and noise reduction device for the wheel, the sound absorption inlets are formed in the porous sound absorption base body, the sound absorption inlets communicated with the sound absorption areas and the convergence areas, and tire cavity resonance noise generated in the running process of a vehicle can enter the convergence areas through the sound absorption inlets and is absorbed by the porous structure of the porous sound absorption base body; and thus, the noise reduction capability of the wheel sound absorption and noise reduction device is improved.

    本发明公开了一种车轮吸声降噪装置及具有其的车轮,其中,车轮吸声降噪装置包括多孔吸声基体和多个吸声结构。多个吸声结构设在多孔吸声基体上,每个吸声结构均具有延伸至多孔吸声基体表面的吸声入口;吸声结构包括汇聚区域和吸声区域,汇聚区域设在多孔吸声基体内且横截面尺寸相同,吸声区域的一端连通汇聚区域另一端形成吸声入口,吸声区域从汇聚区域向多孔吸声基体表面方向延伸时横截面尺寸逐渐增大。根据本发明实施例的车轮吸声降噪装置,在多孔吸声基体上设置吸声入口,且吸声入口连通吸声区域和汇聚区域,车辆在行驶过程中产生的胎腔共振噪声可通过吸声入口进入汇聚区域,并被多孔吸声基体的多孔结构吸收,提高车轮吸声降噪装置的降噪能力。
