Wheel profile for railway vehicle, has contour flattened in area of wheel tread of wheel, where profile is provided with less equivalent tapering, and flange narrowly implemented and flattened

摘要

The profile (1) has a contour flattened in an area of a wheel tread (4) of a wheel. The profile is provided with less equivalent tapering, and a flange (3) is narrowly implemented. The flange is flattened around 2 millimeters. The wheel tread is flattened in a groove around 0.5 millimeters. The tread is designed in a broad and flat manner such that a continuous curvature of the wheel profile is obtained.
