The invention relates to the technical field of rail transit, in particular to a suspension system and a railway freight train traveling device.The suspension system comprises a vertical spring for relieving vertical load from a train body, the two ends of the vertical spring are connected with one end of a suspension hanger, the other end of the suspension hanger is used for being connected with the train body through a hanger seat, and the bottom of the vertical spring is connected with a wheel pair through a connecting gasket; the transverse shock absorber is arranged between the vehicle body and the wheel pair and is perpendicular to the vertical spring, one end of the transverse shock absorber is connected with the vehicle body, and the other end of the transverse shock absorber is fixedly connected with the connecting gasket to provide transverse damping for the wheel pair; when the vehicle vibrates in the vertical direction, the vertical spring can relieve the vertical load from the vehicle body; when the walking device passes through a curve and bears large transverse wheel-rail force, the transverse shock absorbers provide transverse damping in a compression or stretching mode. The added transverse and vertical buffer dampers can reduce the impact of the track on the wheels, eliminate the resonance phenomenon of the vehicle body, and reduce the damage of railway transportation to goods to the maximum extent.
本发明涉及轨道交通技术领域,尤其是一种悬挂系统以及铁路货运车走行装置,包括垂向弹簧,以缓解来自车体的垂向负荷,其两端连接悬挂吊架一端,悬挂吊架另一端用于通过吊架座与车体连接,垂向弹簧底部通过连接垫片与轮对连接;横向减振器,布置于车体与轮对间,其与垂向弹簧垂直设置,并且一端连接车体,另一端与连接垫片固定连接,为轮对提供横向阻尼;当车辆垂向振动时,垂向弹簧能够缓解来自车体的垂向负荷;当走行装置通过弯道并受到较大横向轮轨力时,横向减振器通过压缩或拉伸的方式提供横向阻尼。增加的横向和垂向的缓冲阻尼可减小轨道对车轮的冲击,消除车身的共振现象,最大程度减少铁路运输对货物造成的损伤。
