WHEEL DISC FOR A RAIL VEHICLE

摘要

The invention concerns a wheel disc for a rail vehicle, comprising: a wheel hub surrounding a rotary shaft; a wheel flange; and a web connecting the wheel hub to the wheel flange. The invention is characterized in that a transition curve between the web and the wheel hub and/or a transition curve between the web and the wheel flange is/are formed on at least one axial side in each radial cutting plane such that the transition curve is formed by a Bezier curve, the Bezier curve merging at a constant tangent into the contour of the web and merging at a constant tangent into the contour of the wheel hub or of the wheel flange.
