FIELD: transportation.
SUBSTANCE: chassis frame of a railway vehicle comprises a frame including two longitudinal beams and a cross member connecting the longitudinal beams in the transverse direction. Each longitudinal beam has a free end forming the primary suspending interface for the primary suspending device connected to the corresponding wheel assembly, as well as a pivoting portion integrated with the free end and forming a pivoting connection for the pivot lever connected to the corresponding wheel assembly. Each longitudinal beam has an angular part combined with a free end forming a rack. The pivoting portion is integrated with the angular part. The pivoting portion is embedded in the angular part, and the frame skeleton is made in the form of grey cast iron monolithic component. In the longitudinal direction, the pivoting portion is positioned so as to be located at least partially behind the corresponding free end.
EFFECT: simplifying the design and manufacturing of the frame.
