The invention relates to an automobile suspension swing arm which comprises a swing arm body, four polyurethane linings and two shaft pins. The first end and the second end of the swing arm main body are respectively provided with a first mounting hole and a second mounting hole; the two ends of the first mounting hole and the two ends of the second mounting hole are each provided with a polyurethane lining. And each shaft pin is rotationally arranged in two adjacent polyurethane bushings respectively. According to the invention, the polyurethane bushing is adopted, so that the polyurethane bushing has good tensile strength, tear strength, impact resistance, wear resistance, weather resistance, hydrolysis resistance and oil resistance, and the service life of the bushing is prolonged; lubricating grease is added into the polyurethane bushing, and the pin shaft is rotatably arranged in the polyurethane bushing, so that the problem of abnormal sound during rotation is avoided, the reliability and the stability of the swing arm are improved, and meanwhile, the machining cost of the swing arm shaft pin and the bushing is reduced; the device is simple in structure and reasonable in design, and the stability, reliability and safety of the vehicle are improved.

    本发明涉及一种汽车悬挂摆臂,包括摆臂主体、四个聚氨酯衬套和两条轴销;摆臂主体的第一端和第二端分别设有第一安装孔和第二安装孔;第一安装孔和第二安装孔的两端分别安装有一个聚氨酯衬套;每条轴销分别转动设置在两个相邻的聚氨酯衬套内。本发明通过采用聚氨酯衬套,其具有好的抗拉强度、抗撕裂强度、耐冲击性、耐磨性、耐候性、耐水解性、耐油性,提高了衬套的使用寿命;通过在聚氨酯衬套内添加润滑油脂,并通过销轴转动设置在聚氨酯衬套内,避免转动时出现异响的问题,提高摆臂的可靠性和稳定性,同时降低摆臂轴销及衬套的加工成本;本发明结构简单、设计合理,提升了车辆的稳定性、可靠性、安全性。
