The invention provides an underframe structure for railway vehicle keeping. The underframe structure comprises an underframe and a floor arranged on the underframe. The chassis comprises a framework of a frame structure and sleeper beams, the framework is composed of a plurality of beam body components, the sleeper beams are arranged close to the two ends of the framework, four bearing points are arranged on the framework in the direction of the center line, and each bearing point is used for being connected with a traction base of the two-stage suspension bogie to transmit longitudinal loads and transverse loads; and two mounting stations are formed on the two sides of the framework, and inclined pedal turning plate devices are assembled on the mounting stations. The chassis center sill is different from an existing railway freight freight punctuality chassis center sill in structure, a center sill center plate of a traditional wagon is omitted, a center sill lower cover plate is an integral steel plate with eight bolt hole positions, and the chassis center sill can be connected with a two-line welding bogie with a spiral steel spring serving as a two-line suspension and used for a vehicle to transmit longitudinal loads and transverse loads.

    本发明提供了一种铁路守车用底架结构,包括底架和设置于所述底架的地板;所述底架包括由多个梁体构件构成的框架结构的骨架,以及设置在靠近所述骨架两端的枕梁,其中,所述骨架沿着中心线的方向布置有四个承载点,每个所述承载点用于和两系悬挂转向架的牵引座连接以传递纵向载荷和横向载荷;以及所述骨架的两侧形成有两个安装工位,所述安装工位装配有倾斜式脚蹬翻板装置。本发明的底架中梁与既有铁路货运守车底架中梁的结构不同,该中梁取消了传统货车中梁心盘,中梁下盖板为带8颗螺栓孔位的整体式钢板,能够与二系悬挂为螺旋钢簧的两系焊接转向架连接,用于车辆传递纵向载荷和横向载荷。
