Chassis structure and railway vehicle

The invention relates to the technical field of railway vehicles, and provides a chassis structure and a railway vehicle. The underframe structure comprises an underframe body, and the underframe body comprises at least two cross beams, at least two longitudinal beams perpendicularly fixed to the cross beams and a bearing piece. Wherein a pair of longitudinal beams is arranged between two adjacent cross beams, a first concave area is defined by the cross beams and the pair of longitudinal beams, and supporting surfaces are formed on the upper sides of the pair of longitudinal beams; the bearing piece is fixedly arranged on the lower side of the first concave area and used for forming a first oil storage disc structure in the first concave area. According to the chassis structure and the railway vehicle, the vertical channel area formed by the cross beams and the longitudinal beams can be reasonably utilized, the space occupied by the upper side of the chassis structure when the fuel engine is installed is eff
