摘要

The invention relates to the design of the cast side frame freight car truck. Increasing the connection node vertical columns strength (5) with an inclined zone (4) and bottom chord (3) of the side frame is provided gain-tidal protrusions (9) reinforcement ribs (11) connecting the cylindrical projections-tides (9) with the respective vertical columns ( 5), and in the form of inclined edges (10) of hardness connecting cylindrical protrusion-lug (9) with the zones of the compounds of vertical columns (5) with the inclined zones (4) and bottom chord (3), wherein the length of the inclined edges (10) hardness is formed greater than the width of vertical columns (5) and access to the inclined zone (4), wherein the length of the vertical ribs (11) formed of hardness equal or greater than the diameter «d» tide-cylindrical protrusion (9)
