摘要： A novel freight car truck bolster comprising a top member with a center bowl and support shelves for side bearers, a bottom member with bearing surfaces for swing suspension springing elements, going into diagonal tension members, side walls joining the top and bottom members, vertical longitudinal ribs located between the top and bottom members with their thickness increased in the center bowl area, pockets to install friction wedges. The bottom member has increased thickness in the transition areas of the bearing surfaces into the diagonal tension members, and the vertical ribs have thickness increased at the top of the center bowl area, the rounded transitions of the sloping walls into the bottom member bearing surfaces have a radius exceeding the radius of the rounded transitions of the vertical walls into the said bearing surfaces.

摘要： The invention relates to the field of metallurgy, in particular to the methods for heat treatment of railway rolling stock parts, specifically railway rolling stock unit center plate. The center plate strengthening device contains a power coil and a sprayer, the power coil being implemented as turnable against the center plate central axis and containing a tube with spray cooling openings. The method for railway rolling stock unit center plate strengthening is performed by progressive induction hardening with simultaneous liquid cooling while rotating the center plate strengthening device 360° around the central axis where the center plate treated surfaces undergo induction heating, spray cooling immediately after the heating, and low-temperature volume tempering with a dwelling period.

摘要： The invention relates to the field of heat treatment of metals and may be used for hardening the railway transport automatic coupler parts. The hardening method includes induction heating of the automatic coupler and its subsequent cooling. The induction heating is performed within the automatic coupler part working surface area. The heated surface is cooled by water fed through openings in the coil body.
