The active damping-adjustable wheel noise reduction device comprises a damping cavity fixed to a wheel spoke plate and a damping adjusting mechanism fixed to the damping cavity, the damping cavity comprises a shell, a partition plate arranged in the shell and liquid filling the inner space of the shell, and the partition plate divides the inner space of the shell into an inner part and an outer part; the partition plate is provided with a notch, so that liquid in the inner part and liquid in the outer part are communicated at the notch; the damping adjusting mechanism comprises a movable valve arranged at the notch and a driving motor used for controlling the rotating angle of the movable valve to adjust the opening size of the movable valve so as to achieve damping adjustment. Vibration damping is generated by flowing of the viscous material in the cavity in the spoke plate, consumption of vibration energy of the wheel is achieved, and the effects of vibration reduction and noise reduction are achieved. The size of a valve opening in the middle of the cavity is adjusted through the driving motor, so that dynamic adjustment of damping is achieved.

    本发明公开了主动式阻尼可调车轮降噪装置,包括固定在车轮辐板上的阻尼腔和固定于该阻尼腔的阻尼调节机构,阻尼腔包括壳体、设置于壳体内的隔板和填充壳体内部空间的液体,隔板将壳体内部空间分隔为内外两部分,并且隔板设置有缺口,使内外两部分的液体在该缺口处连通;阻尼调节机构包括设置于缺口处的活动阀门和用于控制该活动阀门转动角度以调节活动阀门的开口大小从而实现阻尼调节的驱动电机。轮辐板上空腔内粘滞材料的流动产生振动阻尼,实现车轮振动能量的消耗,起到减振降噪的作用。通过驱动电机调节空腔中间阀门开口的大小,来实现阻尼的动态调节。
