RAILROAD WHEEL Russian patent published in 2011 - IPC B60B17/00 B60B3/02 B61F13/00 B21H1/04 

FIELD: transport.

SUBSTANCE: invention relates to railway transport, particularly, to railway transport wheels. Proposed wheel consists of all-rolled wheel with rim and rim ring, or all-rolled part comprising hub and rim conjugated by transition radius section with curved disk formed by outer and inner surfaces. Central line of disk radial cross section is shifted along wheel rotational axis at section of its conjugation with hub relative to said central line at disk conjugation with rim toward inner surface. Said shift varies from 30 to 100 mm. Note here that generating lines of disk outer and inner surfaces consist of main radius curves with opposite curvature interconjugated at disk central section while, on hub side and that of rim, with transition radius sections by additional straight or radius section, or without them.

EFFECT: higher operating performances.
