SOLID-ROLLED RAILWAY WHEEL Russian patent published in 2014 - IPC B60B17/00 

FIELD: construction.

SUBSTANCE: curvilinear disc (4) is made so that the ratio of the distance (H₂) from the second point (B) to the medium-wave plane (O-O) to the distance (H₁) from the first point (A) to the medium-wave plane (O-O) makes H₂/H₁=2.0-2.5. The ratio of the radius (R₁) of the section (AY) of the medium line (AB) of the curvilinear disc (4) to the radius (R₂) of the section (BY) of the medium line (AB) of the curvilinear disc (4) makes R₁/R₂=0.4-0.5. The plane (P₁), stretching via the middle of width (f) of the hub (5), is displaced relative to the plane (P₂), stretching via the middle of width (h) of the rim (1), towards the inner surface of the wheel by S=(0.15-0.25)h of width (h) of the rim (1). The ratio of the distance (H₃) from the plane (P₁), stretching via the middle of width (f) of the hub (5), to the medium-wave plane (O-O) to the distance (H₄) from the plane (P₂), stretching via the middle of width (h) of the rim (1), to the medium-wave plane (O-O) makes H₃/H₄=1.35-1.45.

EFFECT: increased service life of a solid-state railway wheel, reduced intensity of railway track wear.
