A tire noise reducing system comprises a wheel rim, a pneumatic tire to be mounted on the wheel rim to form an annular tire hollow, and a noise damper to be disposed in the annular tire hollow, wherein the noise damper is a liquid under use conditions, and the noise damper has a certain volume being capable of changing the cross sectional area of the annular tire hollow irregularly in the circumferential direction during rotating, whereby the mode, amplitude and frequency of resonance of the tire hollow are changed irregularly to damp the resonance. The tire noise reducing system may comprises an apparatus for injecting the foamable liquid damper into the tire hollow, which apparatus comprises a container for the foamable liquid damper, a high-pressure gas source to let the foamable liquid damper from the container, and a nozzle for discharging a mixture of the liquid damper and high-pressure gas foam to be injected into the tire hollow.
一种轮胎降噪系统包括轮辋、安装在轮辋上以形成环形中空轮胎的充气轮胎和设置在环形中空轮胎内的噪声阻尼器,其中噪声阻尼器在使用条件下为液体,噪声阻尼器具有一定的容积,能够在旋转过程中沿圆周方向不规则地改变环形中空轮胎的横截面积,从而不规则地改变中空轮胎的共振模式、振幅和频率以抑制共振。轮胎降噪系统可包括一个将可发泡液体阻尼器注入轮胎中空的装置,该装置包括一个盛放可发泡液体阻尼器的容器、一个用于将可发泡液体阻尼器从容器中放出的高压气源,以及一个用于将液体阻尼器和高压气体泡沫的混合物排出以注入轮胎中空的喷嘴。
