Railway wheel and method of manufacture

摘要

A relationship between each of the wheel rim and hub, and the connecting plate, exists to provide a location for the relative plate-to-rim and plate-to-hub junctions of the wheel. A plate contour may have a convex or concave curvature relative to the wheel outboard face. The curvature at a given location has an associated curvature-depth within a specified range. The wheel provided with the defining parameters has a lower axial flange deflection and a lower residual tensile stress in the region of the wheel rim than is provided by presently available wheels.
