The invention relates to the field of tire machining, and discloses a tire cavity noise reduction device and a tire. The tire cavity noise reduction device comprises a mute element body, a plurality of grooves are formed in the end face of the top of the mute element body, and the grooves are formed in the length direction of the mute element body side by side at intervals; and each groove penetrates through the mute element body along the width direction. The volume and the shape of the inner cavity of the tire can be changed through the arranged mute element body, the purpose of turbulent flow is achieved, propagation resonance of sound waves in the cavity of the tire is reduced, the noise peak value is reduced, and therefore the effect of reducing the noise of the cavity of the tire is achieved; according to the mute element, the grooves formed in the mute element body can release stress brought by road impact and air resistance to the mute element body, the buffering effect is achieved, then the service life of the mute element body is prolonged, the durability of the mute element body is improved, and the maintenance cost is saved.
本发明涉及轮胎加工领域,公开了提供的一种轮胎空腔降噪装置以及轮胎,其中,轮胎空腔降噪装置包括静音元件本体,其顶部端面设有若干个凹槽,若干个凹槽沿静音元件本体的长度方向并列间隔设置,且每个凹槽均沿宽度方向贯通静音元件本体。通过设置的静音元件本体能够改变轮胎内腔的体积与形状,达到扰流的目的,降低了声波在轮胎腔体内的传播共振,使得噪音峰值降低,从而起到了降低轮胎空腔噪音的效果;通过静音元件本体上设置的若干个凹槽能够对路面冲击以及空气阻力给静音元件本体带来的应力进行释放,起到了缓冲的作用,进而提高了静音元件本体的使用寿命以及耐久性,节约了维修成本。
