Noise-reducing wheel and vehicle

Abstract

The invention relates to a noise-reducing wheel and a vehicle. The noise-reducing wheel comprises a rim and a sound-absorbing cotton component. The cotton component is bonded to an outer circumferential surface of the rim, and this outer circumferential surface of the cotton component has a plurality of sound-absorbing grooves. By bonding the cotton component to the rim, during noise vibration, friction is generated with the internal pore wall surface of the cotton component to convert sound energy into thermal energy, thus achieving the noise reduction effect. The bonding process is simplified, and its efficiency is improved. The surface area of ​​the cotton component can be increased, thereby increasing the sound-absorbing area of ​​the pores and enhancing the noise reduction effect. Figure for the abstract: Fig. 1
