RAILWAY WHEEL Russian patent published in 2013 - IPC B60B17/00 B60B3/02 B61F13/00 B21H1/04 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to wheel-tracked machine propulsors. In the case of wheel outer surface, radii of the first and second outer radial curves make 0.04-0.05 of taping diameter. Radius of third outer radial curve makes 0.08 to 0.1 of rolling circuit. Radius of fourth outer radial curve makes 0.07 to 0.09 of rolling circuit diameter while, for disc inner surface, radius of the first inner radial curve makes 0.8-1.0 of rolling circuit. Radii of the second and third inner radius curve makes 0.06-0.08 of rolling circle. Radius of the fourth inner radius curve makes 0.04-0.06 of rolling circle diameter. Note here that first point is shifted from central surface toward in direction opposite the ledge by, at least, 0.08 of rim width. Central point is shifted from central surface for 0.35-0.4 of rim width while second point is shifted toward the ledge from central surface by 0.1 of rim width. Relationship between disc thickness at the first point to that at second point makes 0.7-1.1 while that at central point to that at second point makes 0.7-0.9.

EFFECT: higher operating performances.
