The invention discloses a damping device for an electric drive system, the electric drive system and an installation method of the damping device. The damping device comprises a first plate body and a second plate body, the first plate body and the second plate body are stacked in the thickness direction, and the surfaces, facing each other, of the first plate body and the second plate body form a first vibration reduction face and a second vibration reduction face. The first damping layer is arranged between the first plate body and the second plate body and attached to the first vibration reduction face and the second vibration reduction face. According to the vibration damping device, the first damping layer is arranged between the first plate body and the second plate body, so that the first damping layer can absorb a part of vibration energy and convert the vibration energy into heat energy, and the effect of reducing vibration noise is achieved.

    本发明公开了一种用于电驱系统的减振装置、电驱系统及减振装置的安装方法,所述减振装置包括:第一板体和第二板体,所述第一板体与所述第二板体在厚度方向上叠置且所述第一板体与所述第二板体朝向彼此的表面构造为第一减振面和第二减振面;第一阻尼层,所述第一阻尼层设置于所述第一板体与所述第二板体之间且分别与所述第一减振面和所述第二减振面贴合。根据本发明的减振装置通过在第一板体和第二板体之间设置第一阻尼层,使得第一阻尼层可以吸收一部分振动能量并将之转化为热能,从而达到降低振动噪声的效果。
