The invention relates to a device for detecting eccentricities and wheel flats of rail vehicle wheels within a defined working section using one or more force transducers to detect the vertical forces acting on the rails. The force transducers are configured as load cells that are mounted between the rails (7) and the stationary transversal bars or sleepers (2, 8). The load cells are linked with an evaluation element that determines an average load from the vertical force signals when the working section is traveled on. Said load is compared in the evaluation element with the signal course over time during the travel of the wheel across the working section. If a defined deviation is exceeded, this excess is considered a measure of the eccentricity and is signaled or displayed as a wheel flat. The inventive device is further provided with transverse stress transducers that represent shunt correctors and rail switches so that the device can be used for the simultaneous high-precision weighing of the wagons, for overload control and control of the center of gravity. |
