The invention discloses a bush assembly, a power assembly suspension and a vehicle, the bush assembly comprises a first vibration reduction body, the first vibration reduction body comprises an outer cylinder, an inner cylinder and a first elastic body, the first elastic body is connected between the outer cylinder and the inner cylinder, and a containing groove is formed in the side, away from the first elastic body, of the outer cylinder in the axial direction; and the second vibration reduction body is arranged in the containing groove and connected with the first vibration reduction body, and a gap is formed between the second vibration reduction body and the outer cylinder in the radial direction. When the radial external impact on the lining assembly is small, the first vibration reduction body deforms to play a buffering role, when the radial external impact on the lining assembly is large, the first vibration reduction body deforms and makes contact with the second vibration reduction body, and the second vibration reduction body is made into the first vibration reduction body to prevent the first vibration reduction body from deforming in a larger range. Under the condition that the rigidity of the first vibration reduction body is low, the durability is improved, and the service life of the first vibration reduction body is prolonged.

    本发明公开了一种衬套组件、动力总成悬置和车辆,衬套组件包括:第一减振体,第一减振体包括:外筒、内筒和第一弹性体,第一弹性体连接在外筒和内筒之间,外筒在轴向方向远离第一弹性体的一侧形成容纳槽;第二减振体,第二减振体设置于容纳槽内且和第一减振体相互连接,第二减振体与外筒沿径向方向形成间隙。衬套组件受到径向外部冲击较小时,第一减振体发生形变起缓冲作用,衬套组件受到径向外部冲击较大时,第一减振体发生形变并与第二减振体接触,第二减振体制成第一减振体防止其发生更大范围的形变,可以在将第一减振体刚度较低的情况下,提高耐久性能,延长第一减振体的使用寿命。
