The invention relates to a large-tonnage mine truck rear suspension system. The large-tonnage mine truck rear suspension system comprises a damping mechanism and a fixing mechanism. The large-tonnage mine truck rear suspension system is fixed to an axle through the fixing mechanism. Each oil-gas spring is connected to a respective oil-gas spring bracket, is connected with the axle through each oil-gas spring and is connected to a truck frame through the oil-gas spring bracket, and the oil-gas springs can effectively meet the large-tonnage bearing capacity and achieve the vehicle damping and buffering effects; the truck frame and the axle are fixed through a fixing structure so as to realize stable operation; a first upper thrust rod and a second upper thrust rod form a V-shaped thrust rod structure, and a first lower thrust rod and a second lower thrust rod are of a straight thrust structure. The ratio of the length of the V-shaped thrust rod to the length of a straight push rod is 2: 3; each thrust rod is connected to a corresponding thrust rod support on a respective axle, the first upper thrust rod and the second upper thrust rod are symmetrically arranged on the axle, and an included angle is formed between the first upper thrust rod and the second upper thrust rod.

    本发明涉及大吨位矿用车后悬架系统其包括减震机构和固定机构,通过固定机构将本发明的大吨位矿用车后悬架系统固定至车桥;各油气簧分别连接至各自的油气簧支架,通过各油气簧连接车桥,通过油气簧支架连接至车架,油气簧能够有效满足大吨位承载能力以及达到车辆减震与缓冲作用;通过固定结构固定车架与车桥以实现稳定运行;所述第一上推力杆和所述第二上推力杆形成V型推力杆结构,所述第一下推力杆和第二下推力杆为直推结构;V型推力杆的长度与直推杆的长度之比为2:3;各推力杆均连接至各自的车桥上对应的推力杆支座,所述第一上推力杆和所述第二上推力杆在车桥上对称设置且所述第一上推力杆和所述第二上推力杆具有夹角。
