The invention discloses a railway vehicle framework, which comprises two side beams and a cross beam connected between the two side beams. The framework is of a hollow sealing structure with a hollowcavity; primary air spring mounting seats are arranged at the two ends of each side beam, the upper parts of the primary air spring mounting seats are connected with the corresponding side beams in asealed mode, the lower parts are respectively provided with spaces for accommodating primary air springs, and first air inlet holes communicated with the primary air springs and the hollow cavity areformed in the connecting positions of the mounting seats and the side beams; and a secondary air spring mounting seat is arranged in the middle of each side beam, and first air inlet holes communicated with the hollow cavity are formed in the mounting seats. Therefore, the framework with the hollow sealing structure can communicate the secondary air springs, the framework and the primary air springs to form an integrated su
