The invention relates to an elastic wheel noise reduction plate which comprises a first noise reduction unit, a second noise reduction unit and a middle damping layer, and the first noise reduction unit comprises a first upper metal plate, a first damping layer and a first lower metal plate which are sequentially stacked; the second noise reduction unit comprises a second upper metal plate, a second damping layer and a second lower metal plate which are sequentially stacked, the second lower metal plate comprises an extension area, the extension area is connected with the first lower metal plate through a middle damping layer, a center plate of the wheel is provided with a hollow groove, and the first noise reduction unit is connected with the side wall of the center plate. And the second noise reduction unit forms a cantilever structure at the hollow groove. Compared with the prior art, the step type structure is adopted, staggering between the plates is increased, the deformation amplitude of the damping layer during vibration is increased, and particularly, the axial energy absorption effect is improved, the energy dissipation effect is increased, and the noise reduction effect is improved.

    本发明涉及一种弹性车轮降噪板,包括第一降噪单元、第二降噪单元和中间阻尼层,第一降噪单元包括依次层叠设置的第一上金属板、第一阻尼层和第一下金属板,第二降噪单元包括依次层叠设置的第二上金属板、第二阻尼层和第二下金属板,第二下金属板包括延展区域,该延展区域通过中间阻尼层连接第一下金属板,车轮的幅板上设有镂空槽,第一降噪单元连接幅板的侧壁,使第二降噪单元在镂空槽处形成悬臂结构。与现有技术相比,本发明采用了阶梯形式的结构,增大了板与板之间的交错,使振动时阻尼层的变形幅度增大,尤其提高了轴向的吸能,增大能量的耗散提高降噪的效果。
