RAILWAY WHEEL Russian patent published in 2020 - IPC B60B17/00 B61F13/00 

FIELD: vehicle wheels.

SUBSTANCE: railway wheel is a solid-rolled part with a nominal outer diameter (D) and has an axis of rotation (Z), a conditional plane (P), perpendicular to the axis of rotation of the wheel (Z) and comprises rim 1 with ridge 2, hub 3 and disc 5 of curvilinear shape formed by outer 5 and inner 6 surfaces and has theoretical central axial line 7 of radial section, conjugated with rim 1 with transient radius sections 8 and with hub 3 transient radius sections 9. Theoretical central axial line 7 of radial section of disc 4 on section of interface of disc 4 with hub 3 is displaced along axis of rotation (Z) of wheel relative to theoretical central axial line 7 of radial section of disc 4 on section of interface of disc 4 with rim 1 in direction to ridge 2. Theoretical central axial line 7 of radial section of disc 4 and, accordingly, each of forming outer 5 and inner 6 surfaces of disc 4 consist of three main radius curves and rectilinear inclined section.

EFFECT: improved operational characteristics of railway wheel.
