The invention relates to a composite balanced suspension system of a commercial vehicle, which is characterized in that a plate spring is fixed on a bearing hub of a balance shaft process assembly, and the balance shaft process assembly is fixed on a frame longitudinal beam; the upper end of the middle axle is connected with the upper end of the rear axle through an upper thrust rod assembly, and the lower end of the middle axle is connected with the lower end of the rear axle through a lower thrust rod assembly. One end of the main leaf structure at the lowermost end of the plate spring extends to form a first mounting part, and the other end extends to form a second mounting part; the lower end of the first air spring is mounted on the first mounting part; the lower end of the second air spring is mounted on the second mounting part; the upper end of the first air spring and the upper end of the second air spring are respectively connected with the lower end of the frame longitudinal beam; the control system is connected with the first air spring and the second air spring. According to the composite balanced suspension system for the commercial vehicle, the technical problems that the vibration frequency is large during no-load and the bearing performance is poor during full load are solved.
本发明涉及一种商用车复合平衡悬架系统,板簧固定在平衡轴工艺合件的轴承毂上,平衡轴工艺合件固定在车架纵梁上;中桥的上端通过上推力杆总成与后桥的上端连接,中桥的下端通过下推力杆总成与后桥的下端连接。位于板簧最下端的主片结构的一端延长后形成第一安装部,另一端延长后形成第二安装部;第一空气弹簧的下端安装在第一安装部,第二空气弹簧的下端安装在第二安装部;第一空气弹簧的上端及第二空气弹簧的上端分别与车架纵梁的下端连接;控制系统分别与第一空气弹簧及第二空气弹簧连接。该商用车复合平衡悬架系统,解决了空载时振动频率大、满载时承载性能差的技术问题。
