The invention provides a noise reduction wheel and a vehicle, and relates to the technical field of vehicles. The noise reduction wheel comprises a wheel body and a rim arranged on the wheel body. The rim comprises a supporting ring and two check rings arranged on the two sides of the supporting ring. The noise reduction wheel is characterized in that an annular noise reduction plate is arranged between the two check rings in a winding mode, a plurality of through holes are formed in the annular noise reduction plate, and an annular cavity is formed by the annular noise reduction plate and the rim. According to the noise reduction wheel, the annular noise reduction plate is arranged on the rim, the annular cavity is formed by the annular noise reduction plate and the rim, the noise reduction principle of a Helmholtz resonator is utilized, when an automobile runs, the noise of the wheel can be reduced, the noise generated when the automobile runs is reduced, potential safety hazards are reduced, and the noise reduction wheel does not affect tire installation.
本申请提供一种降噪车轮及车辆,涉及车辆技术领域。该降噪车轮包括:车轮本体和设置在车轮本体上的轮辋,轮辋包括支撑环和设置在支撑环两侧的两个挡圈;其特征在于,两个挡圈之间绕设有环形降噪板,环形降噪板上开设有多个通孔,环形降噪板与轮辋形成有环形空腔。本申请的降噪车轮,在轮辋上设置了环形降噪板,环形降噪板与轮辋形成有环形空腔,利用了亥姆霍兹共振器降噪的原理,在汽车行驶时,能够降低车轮的噪声,降低了汽车行驶时的噪声,减少了安全隐患,并且,降噪车轮又不影响轮胎安装。
