The invention relates to the field of automobile accessory equipment, and provides a bushing structure and an automobile lower swing arm assembly.The bushing structure comprises a bushing body, two first vibration reduction holes are distributed in the circumferential direction of the bushing body at intervals, and the first vibration reduction holes extend in the axial direction of the bushing body; the hole wall of the first vibration reduction hole is provided with an arc-shaped part, and a first convex peak part, a second convex peak part and a third convex peak part which are opposite to the arc-shaped part; the peak point of the second convex peak part is higher than the first convex peak part and the second convex peak part; when the axial deflection of the bushing body is smaller than or equal to the first deflection, the second convex peak part is separated from the arc-shaped part; when the axial deflection of the lining body is larger than the first deflection and smaller than or equal to the second deflection, the second convex peak part abuts against the arc-shaped part. When the axial deflection of the lining body is larger than the second deflection, the first convex peak part, the second convex peak part and the third convex peak part abut against the arc-shaped part, the whole lining structure has the good buffering and damping performance on a vehicle body chassis, and the controllability and stability of a vehicle are improved.

    本发明涉及汽车配件设备领域,提供一种衬套结构及汽车下摆臂组件,衬套结构包括:衬套本体,衬套本体的周向间隔分布有两个第一减振孔,第一减振孔沿衬套本体的轴向延伸;第一减振孔的孔壁具有弧形部和与弧形部相对的第一凸峰部、第二凸峰部及第三凸峰部,第二凸峰部的峰点高于第一凸峰部和第二凸峰部;衬套本体在其轴向的挠度小于或等于第一挠度时,第二凸峰部和弧形部分离;衬套本体在其轴向的挠度大于第一挠度并小于或等于第二挠度时,第二凸峰部和弧形部抵接;衬套本体在其轴向的挠度大于第二挠度时,第一凸峰部、第二凸峰部和第三凸峰部均与弧形部抵接,整个衬套结构对车身底盘具有较佳的缓冲减震性能,提升了车辆的操控性和平稳性。
