Abstract

A device for determining geometry characteristic values of a wheel profile on a rolling wheel of a rail vehicle that includes a first sensor arrangement, which has a first non-contact measuring distance sensor, which is oriented at a reference surface in the form of the inner planar surface of the rolling wheel, and at least one further non-contact measuring distance sensor, which is oriented at a defined angle of incidence at the wheel surface of the rolling wheel facing the rail or the wheel surface of the rolling wheel to be examined. Both distance sensors are arranged a defined distance to the rail. An electronic evaluation device calculates the geometry characteristic values from the detected distance signals. The first and the further non-contact measuring distance sensor use a frequency-modulated continuous-wave radar (FMCW), and a lens is used to bundle the radar waves and thus to define a measuring spot.
