The invention discloses a secondary suspension system for a suspension type freight sky train. The system at least comprises a connecting device for realizing interconnection of a framework and a sleeper beam, and the framework and the sleeper beam are movably connected through the connecting device; a through hole structure is arranged at the end of the framework, two connecting lug handles are arranged at the top end of the sleeper beam, and hole body structures are arranged at the same positions of the lug handles respectively. The connecting device at least comprises a traction pin and a connecting joint, the framework is arranged between two ear handles of the sleeper beam, the traction pin respectively penetrates through the ear handles and a hole body structure at the end part of the framework, and a flexible connecting joint is also arranged between the traction pin and the framework. By means of the suspension system, elastic connection of the framework and the sleeper beam isachieved, the framework and the sleeper beam can achieve relative rotation and relative up-down settlement within a certain range after being connected, and therefore vibration of a vehicle body is effectively relieved, the service life of the vehicle body and the bogie is prolonged, and the maintenance cost is reduced.
本发明公开了一种悬挂式货运空铁用二系悬挂系统,所述悬挂系统至少包括用于实现构架和枕梁互连的连接装置,所述构架和枕梁经连接装置实现活动连接;所述构架的端部设有通孔结构,所述枕梁顶端设有两连接耳柄,且所述耳柄上相同位置处分别设有孔体结构;所述连接装置至少包括牵引销和连接关节,所述构架设置于枕梁的两耳柄之间,所述牵引销分别贯穿于耳柄与所述构架端部的孔体结构,且所述牵引销与所述构架间还设有柔性的连接关节。通过本悬挂系统实现了构架和枕梁的弹性连接,连接后构架和枕梁能够实现一定范围的相对转动和相对上下沉降,从而有效的缓减了车体的振动,增加了车体和转向架的实用寿命,降低了维护成本。
