Abstract
In the case of a system for detecting excessively heated wheel bearings and/or wheel tires of rail vehicles, a device is inserted into the path of the beam extending from a measuring point to a heat radiation sensor that distorts the resulting image and, in particular, widens it at least uniaxially. This device also serves to detect the measuring point when wheel axles shift in an axial direction. A system of this type may be formed by using a distorting optical device (6) which permits the imaging of a correspondingly widened field (4).
