The closest technical solution (adopted as a prototype) is the supporting structure of a double-decker passenger car (author's certificate of the USSR No. 1402464, V61D 1/00, 17/04, decl. 04.16.1986, publ. 15.06.1988. Bull. No. 22) , the frame of which contains end spinal beams mounted in cantilever parts of the frame, pivot beams and buffer beams, upper crossbars, longitudinal strands of the console parts, which are connected by braces located in the plane of the car sidewalls with longitudinal strands of the lower middle part of the frame, and each end spinal beam in transition the first zone is connected to the middle lowered part of the frame by its tip, consisting of upper and lower sheets, interconnected by vertical walls, intermediate transverse beams connecting the longitudinal strapping of the middle lowered part of the frame.

The technical result consists in the implementation (manufacture) of a body frame of a railway carriage comprising end spinal beams mounted in cantilever parts of the frame, pivot and buffer beams, upper crossbars, longitudinal strapping of the console parts, which are connected by braces located in the plane of the sidewalls of the carriage with longitudinal strapping of the middle lower part frames, and each end spinal beam in the transition zone is connected to the middle lower part of the frame by its tip, consisting of upper and lower l of the joints, interconnected by vertical walls, intermediate transverse beams connecting the longitudinal strapping of the middle lower part of the frame, each cantilever part of the frame is equipped with two longitudinal beams installed between the upper cross member and the pivot beam, and each transition zone with a lower cross member, two broken beams connecting the upper and lower cross members, the upper and lower curly sheets, interconnected by two flat longitudinal and two curved vertical ribs and connected the longitudinal strapping of the middle lower part of the frame, as well as the lower cross member with the extreme intermediate transverse beam, while the edge of the upper figure sheet protruding beyond the edge of the lower cross section is connected to the upper sheet of the tip of the spine, the lower figure sheet is connected to the bottom sheet of the tip of the spine, the aforementioned vertical the walls of which are parallel, and each longitudinal and each broken beam is made with a vertical shelf located in the same plane with a flat longitudinal edge.

In addition, each vertical wall of the end of the spinal beam and the corresponding longitudinal section of the curved vertical rib are located in the same plane, in the transition zone, the end of the spinal beam from the bottom is reinforced with a reinforcing element, the connection zone of the longitudinal strands of the cantilever parts with the braces from the bottom is reinforced with a reinforcing element, with each reinforcing element made in the form of a trough-shaped profile.

Additional technical result is expressed in the following.

The presence in each cantilever part of the frame of two longitudinal beams installed between the upper cross member and the pivot beam allows you to unload the corresponding sections of the longitudinal strapping of the cantilever parts of the frame and ensures uniform application of longitudinal loads to the upper cross member.

The presence in each transition zone of the lower cross member, two broken beams connecting the upper and lower cross members, allows you to unload the braces connecting the longitudinal strapping of the cantilever and middle lower parts of the frame, and ensures uniform application of longitudinal loads to the lower cross member.

The presence in each transition zone of the upper and lower curly sheets, interconnected by two flat longitudinal and two curved vertical ribs and connecting the longitudinal strapping of the lower middle part of the frame, as well as the lower cross member with the extreme intermediate transverse beam, allows the most optimal transmission of longitudinal loads from the console parts on the longitudinal strapping of the middle lowered part of the frame.

The connection of the edge of the upper figured sheet protruding beyond the edge of the lower cross member with the upper sheet of the tip of the spine and the connection of the lower figured sheet with the lower sheet of the tip of the spine, as well as the parallel arrangement of the vertical walls of the tip of the spine, increases the rigidity of the frame in the transition zones, and also allows the best transmission longitudinal loads from end spinal beams to longitudinal strapping of the middle lower part of the frame.

The implementation of each longitudinal and each broken beam with a vertical shelf located in the same plane with a flat longitudinal rib will provide the required bearing capacity in the areas of redistribution of longitudinal loads from the cantilever parts of the frame to the longitudinal strapping of the lower part of the frame.
