The invention discloses a three-shaft semitrailer suspension structure which comprises a front spring support, a middle front spring support, a middle rear spring support, a rear spring support, a middle front balance arm, a middle rear balance arm, a first plate spring assembly and a second plate spring assembly. One end of a first plate spring assembly is connected with the front spring support, the other end of the first plate spring assembly is connected with the middle front spring support, one end of the other first plate spring assembly is connected with the middle rear spring support, and the other end of the other first plate spring assembly is connected with the rear spring support. The second plate spring assembly is arranged between the middle-front spring support and the middle-rear spring support, one end of the second plate spring assembly is connected with the middle-front spring support, the other end of the second plate spring assembly is connected with the middle-rear spring support, loads on each tire are evenly distributed, and the problems that the tires of a vehicle are rubbed and braking is abnormal are solved; the dead weight of the whole vehicle is reduced, the cost is reduced, energy is saved, emission is reduced, and economic benefits are The stability is good.
本发明公开了一种三轴半挂车悬架结构,包括前簧支架、中前簧支架、中后簧支架、后簧支架、中前平衡臂、中后平衡臂、板簧组件一和板簧组件二,前簧支架、中前簧支架、中后簧支架和后簧支架分别对称与车架下端焊接,中前平衡臂与中前簧支架铰接,中后平衡臂与中后簧支架铰接,一个板簧组件一一端与前簧支架连接,另外一端与中前簧支架连接,另外一个板簧组件一一端与中后簧支架连接,另外一端与后簧支架连接,板簧组件二设于中前簧支架和中后簧支架之间,且一端与中前簧支架连接,另外一端与中后簧支架连接,每个轮胎上的载荷分布均匀,解决了车辆磨胎和制动异常的问题;降低了整车自重、降低成本、节能减排、经济效益好;稳定性好。
