WHOLE-ROLLED RAILWAY WHEEL Russian patent published in 2017 - IPC B60B17/00 B60B3/02 B61F13/00 B21H1/04 

FIELD: transportation.

SUBSTANCE: railway wheel structure includes a rim, consisting of rolling surface, a rib and side surfaces, limited by the rim inner diameter from the outer and inner sides, a hub and a disc formed by the outer and inner surfaces. Central line of disc radial cross section is shifted along wheel rotational axis at section of its conjugation with hub relative to said central line at diskc conjugation with rim toward inner surface. And generating lines of disk outer and inner surfaces consist of main radius curves with opposite curvature interconjugated at disc central section while, on hub side and that of rim, with transition radius sections. The value of said displacement is from 0.075 to 0.150 of the width of the rim, the middle line of the disc radial section at its conjugation with the rim is located at a distance from 0.5 to 0.6 of the rim width of from its inner side surface.

EFFECT: increase the strength of the wheel while reducing the weight.
