solebar of bogie of freight railroad CAR

摘要

The invention relates to carriage engineering. A solebar of bogie of freight railroad car is made in the form of a continuous casting, which contains upper and lower, with a tray for installation of springs, horizontal belts. The belts create together with vertical columns a spring opening, upper and lower inclined belts of channel-shaped section, which pass into a horizontal above-box section of box-shaped cross section. Vertical external jaw guides of box opening adjoin the latter. The internal jaw guides are connected with the straight portions of lower inclined belt. The wall of lower inclined belt from the vertical column to horizontal above-box section is continuous wedged. U-shaped internal jaw is connected with it. The wall of inclined belt in the place of transition into the above-box section has maximum thickness. The curvature of joining with the above-box section is minimum for such connected surfaces. Technical result: increase of reliability with simultaneous simplification of the design.
