The invention provides a railway freight vehicle and a suspended floor device thereof, and belongs to the technical field of railway freight vehicles. The suspended floor device is arranged on the vehicle body chassis of the railway freight vehicle; the suspended floor device comprises a steel structure chassis, a floor and a plurality of buffer devices; the buffer devices are used for connectingthe steel structure chassis with the vehicle body chassis, and the floor is arranged on the upper side, far away from the vehicle body chassis, of the steel structure chassis; the plurality of bufferdevices are uniformly distributed between the steel structure chassis and the vehicle body chassis; and the rigidity of the plurality of buffer devices is smaller than that of a main suspension device; a plurality of areas between the steel structure chassis and the vehicle body chassis are connected through the buffer devices, so that vibration generated at different positions during the runningof the freight vehicle is basically absorbed by the buffer devices, and therefore, noise is reduced, and quiet and comfortable living conditions and rest environments can be provided for passengers.

    本发明提供了一种铁路货运车辆及其悬浮地板装置,属于铁路货运车辆技术领域。所述悬浮地板装置用于设置在铁路货运车辆的车体底架上,所述悬浮地板装置包括钢结构底架、地板以及多个缓冲装置,所述缓冲装置用于将所述钢结构底架与车体底架连接,所述地板设置在所述钢结构底架背离所述车体底架的上侧;其中,多个所述缓冲装置均匀分布在所述钢结构底架与车体底架之间,多个缓冲装置的刚度小于主悬挂装置。在钢结构底架和车体底架之间的多个区域用缓冲装置进行连接,使得货车运行时不同位置产生的振动基本都被这些缓冲装置吸收,且减少了噪音的产生,可以为乘客提供安静舒适的生活条件和休息环境。
