FIELD: transport.

SUBSTANCE: intention relates to rolling stock wheels. Proposed wheel comprises rim, hub and disk jointing them together. Disk radial cross section is curved with outward bend in its centre. Note here that size "b", i.e. shift of the disk central line from hub centre, at the point the disk abuts the hub fluting plane, makes 8-19 mm in direction along wheel outer surface, while size "a", i.e. shift of the disk central line from hub centre, at the point the disk abuts the rim fluting plane, from the aforesaid point makes 27-38 mm in direction along wheel outer surface. Note also that disk thickness, without fluting planes at the points it abuts the rim and hub, varies all along is circumference or along part of the latter.

EFFECT: longer life and reliability due to optimised shape and sizes.
