The invention belongs to novel technologies of railway trucks and relates to a railway truck chassis. The railway truck chassis comprises a middle beam assembly, a longitudinal beam assembly parallel to the middle beam assembly, a sleeper beam assembly perpendicularly fixed to the middle beam assembly, cross beams perpendicularly fixed to the middle cross beam assembly, end beams arranged at the two ends of the middle beam assembly and a floor laid on the middle beam assembly. The floor is formed by splicing two arcs and a straight plate. The floor has the function of a groove type lower side beam of a traditional railway truck. The end of an upper cover plate of each cross beam is arc and is welded to the arc floor. By the adoption of the railway truck chassis, according to the stress conditions, the sectional size is reasonably selected, the railway truck chassis is designed according to the principle of constant structural strength, the structure is simple, the dead weight is light, the appearance is novel, the connection mode of the components is reliable, the cross beams with arcs and the arc floor form a hidden lower side beam of the chassis, the deed weight of a truck is reduced, the complete discharging rate of goods is increased, and the visual effect of the integrated appearance is improved.
