SOLID ROLLED RAILWAY WHEEL Russian patent published in 2023 - IPC B60B17/00 B61F13/00 B21H1/04 

FIELD: automotive industry.

SUBSTANCE: central line 6 of the wheel in the place of the radial section of the rim 1 is displaced along the axis of the wheel relative to the center line 6 of the wheel in the place of the radial section of the hub 2 towards the outer curved surface 4. The generatrix of the outer curved surface 4 consists of at least two conjugate outer curves R1 and R2 with opposite curvature. The first outer curve R1 is associated with the rim 1 by the first outer transition section R3, the second outer curve R2 is associated with the hub 2 by the second outer transition section R4. The generatrix of the inner curved surface 5 consists of at least two conjugate inner curves R5 and R6 with opposite curvature. The first inner curve R5 is mated with the rim 1 by the first inner transition R7. The second inner curve R6 is connected to the hub 2 by a second inner transition section R8. The junction point O1 of the first outer curve R1 and the second outer curve R2 is removed from the wheel axis at a distance L1=0.274-0.276 of the wheel tread circle diameter. Conjugation point O2 of the first internal curve R5 and the second internal curve R6 is removed from the wheel axis at a distance L2=0.297-0.299 of the wheel tread circle diameter.

EFFECT: increase in axial rigidity and thereby ensuring a constant distance between the rims of two wheels in the wheelset when passing curved sections of the track due to the optimal curvature of the disk.
