The invention provides a multi-connecting-rod rear suspension structure and a mining dump truck. The multi-connecting-rod rear suspension structure comprises an upper connecting rod, at least two force rods and at least two hydraulic rods. The front end of the upper connecting rod is hinged to a frame in a first direction, and the rear end is hinged to the top of a rear axle housing in a second direction perpendicular to the first direction. The front end of each force rod is hinged to the bottom of the frame in the first direction, the rear end of each force rod is hinged to the bottom of the rear axle housing in the second direction, and the at least two force rods are axially arranged at intervals along the rear axle housing. The lower end of each hydraulic rod is hinged to the top of the rear axle housing in the first direction, the upper end of each hydraulic rod is hinged to the frame in the first direction, and the at least two hydraulic rods are arranged at intervals in the axial direction of the rear axle housing. Through the design, the stress of the frame is uniform and reasonable in the running process of the dumper, meanwhile, the operation stability and smoothness of the whole dumper are guaranteed through the multi-connecting-rod structure, and the reliability of the mining dumper is improved. The mining dump truck can meet the performance requirement of the whole truck and is suitable for the application environment of the mining dump truck in mines.

    本发明提出一种多连杆后悬挂结构及矿用自卸车。多连杆后悬挂结构包含上连杆、至少两根力杆以及至少两根液压杆。上连杆前端沿第一方向铰接于车架,后端沿垂直于第一方向的第二方向铰接于后桥壳顶部。每根力杆前端沿第一方向铰接于车架底部,后端沿第二方向铰接于后桥壳底部,至少两根力杆沿后桥壳轴向间隔布置。每根液压杆下端沿第一方向铰接于后桥壳顶部,上端沿第一方向铰接于车架,至少两根液压杆沿后桥壳轴向间隔布置。通过上述设计,本发明能够使车辆在运行中车架受力均匀、合理,同时多连杆结构保证了整车的操纵稳定性和平顺性,提高了矿用自卸车的可靠性。本发明能够满足整车性能要求,适于矿用自卸车在矿山中的应用环境。
