Abstract

See full text

The present invention concerns a method and a device for inspecting railway wheels with respect to use-related wear and/or a material defect. The task of the present invention is to create a technical solution in this regard by means of which various configurations of railway wheels can be tested in a short time. In particular, an inspection should be carried out in override mode so that the test results for a complete train can be prepared during the passage time over an allocated test device. This task is accomplished in that the rolling railway wheelset passes through a spatially restricted magnetic field that is coupled through the rails along which the allocated rail vehicle is guided. For this purpose, a device is used in which an electromagnet (4; 5) is arranged between the rails (2; 3) on which a measuring coil is also configured for registering changes in the magnetic flux.
