Abstract

FIELD OF THE INVENTION The invention relates to railway transport and relates to the construction of bunker car frames. The purpose of the invention is to reduce the metal frame and improve the manufacturability of assembly work. The supports of the 7 bunkers located in the zones of the intermediate and end transverse beams are made in the form of arches, the ends 11 of which rest on the side beams 2. The ends 11 of the extreme support on each cantilever part of the frame are rigidly connected by a connecting element 12 with a vertical sheet of the end beam 3, and the extreme stop 10 is rigidly connected to the vertical sheet end of the beam. 1 hp f-ly, 4 ill. with

The invention relates to railway transport, in particular to the design of car frames with tilting bins, mainly for petroleum bitumen.

The purpose of the invention is to reduce metal scrap and improve the processability of assembly work.

Figure 1 shows the frame of a railroad bunker car, general view; in Fig.2, section A-A in Fig .; on fig.Z - section bb in figure 1, fig, 4 is a view; In on fIgoz,

The frame consists of. zsrebtovoy 1 and side 2 beams5 interconnected by end 3, pivot; 4 and intermediate 5 transverse beams, averages 6, and an extreme 7 support of the bunkers rigidly fixed on the upper half- like 8 ridge beams 1, an average 9, and an extreme 10 stop of the bunkers.

The supports 6 and 7 of the bunkers, located in the zones of the intermediate 5 and end 3 bats, are extended into arches, the ends 11 of which rest on the side beams and 2, together with beams 3 and 5 form rigid outlines "The ends 11 of the extreme support 7 on the deck to: onsole. parts of the frame are rigidly connected between themselves and with the vertical sheet of the end beam 3 by the connecting element 12, and the extreme stop 10 is rigidly connected to the vertical sheet 13,

The vertical load, - perceived by the supports 6 and 7, is transmitted to the lateral base 2 with the ends 11, working in compression for compression. With: this end 3 and intermediate 5 bgshki, vsoln

significantly lower stiffness in the vertical direction as compared to the quality of the side beams 2, is practically not loaded with vertical forces, and the intermediate beams 5 experience slight bending moments. The cantilever parts of the sill beam I, whose stiffness is comparable to the rigidity of the side beams 2, partially perceive the vertical loads from the supports 7 through the connecting elements 12 and the vertical sheets 13. In addition, the longitudinal load acting on the extreme stop 10 is transmitted to the shelves 8 of the spinal 1 and the emerging horizontal component of the bending moment is perceived by the vertical sheet 13 of the end beam 3,
