The invention discloses a middle-rear axle balanced suspension system of a large transport vehicle, which adopts a balanced suspension structure, two groups of balance arms are lapped between a middle axle and a rear axle, and two ends of the balance arms are respectively supported by a front bracket and a rear bracket; the upper support balance arm of the bracket is provided with an arc surface limit, and the lower support axle is provided with an anti-shear pin pair limit; a balance shaft is connected between the two balance arms in a lap joint mode, a limiting pin is arranged between a balance shaft supporting seat and the balance shaft, the balance shaft supporting seat is supported by a lower thrust rod connecting seat, and an anti-shear pin is arranged between the lower thrust rod connecting seat and the balance shaft supporting seat in a matched mode. A balance shaft is clamped by the balance shaft supporting seat and the frame connecting seat together; limiting annular bosses are arranged on the inner sides of the balance shaft supporting seat and the frame connecting seat; two upper thrust rods and four lower thrust rods are arranged. The rear suspension system can bear the weight as high as 100 tons, and is simple in structure, light in weight, multiple in hidden limiting and stable in structure.
本发明公开一种大型运输车辆中后桥平衡悬架系统,采用平衡式悬架结构,两组平衡臂搭撑在中后桥之间,两端分别由前、后支架支撑;支架上部支撑平衡臂设置有圆弧面限位,下部支撑车桥设置有抗剪销对限位;在两平衡臂之间搭接平衡轴,平衡轴支撑座与平衡轴之间设置有限位销,平衡轴支撑座由下推力杆连接座支撑,下推力杆连接座与平衡轴支撑座之间互配有抗剪销;平衡轴支撑座与车架连接座共同夹设平衡轴;平衡轴支撑座与车架连接座内侧都设置有限位环形凸台;本发明设置上二下四推力杆。本发明后悬架系统能够承载高达100吨的重量,结构精简,重量轻,隐形限位多,结构平稳。
