The invention discloses a composite bushing, an automotive suspension and an automobile. The composite bushing comprises a hydraulic bushing with main spring rubber and a buffer bushing, the buffering bush is provided with an elastic buffering layer, is arranged on the periphery of the hydraulic bush in a sleeving mode in the axial direction of the hydraulic bush and surrounds the main spring rubber. Wherein the hardness of the elastic buffer layer is smaller than that of the main spring rubber, and the elastic buffer layer is used for generating elastic deformation at least when the composite bushing is subjected to at least one of a radial load, a torsional load and a deflection load. The hydraulic bushing is sleeved with the buffering bushing with the small dynamic stiffness to form a rigidity decoupling composite structure, part of high-frequency small-amplitude radial vibration is absorbed by means of the characteristic that the buffering bushing is small in dynamic stiffness, and low-frequency large-amplitude vibration is absorbed by means of the hydraulic bushing.

    本申请公开了复合衬套、汽车悬架及汽车,该复合衬套包括具有主簧橡胶的液压衬套和缓冲衬套;缓冲衬套具有弹性缓冲层,沿液压衬套的轴向套设于液压衬套的外周,且包围主簧橡胶;其中,弹性缓冲层的硬度小于主簧橡胶的硬度,且弹性缓冲层用于至少在复合衬套受到径向载荷、扭转载荷以及偏摆载荷中的至少一种时产生弹性形变。通过在液压衬套的外部套设动刚度较小的缓冲衬套,组成刚度解耦的复合结构,利用缓冲衬套动刚度小的特点吸收部分高频小振幅的径向振动,利用液压衬套吸收低频大振幅的振动。
