Abstract
In the case of a device for detecting the spatial orientation of excessively heated points of wheel bearings and/or wheel running treads of rail vehicles, it is suggested that a deflecting device, such as an oscillating mirror 5, that can be varied periodically in its slope, be inserted into the path of the rays from a measuring point to a heat radiation sensor 7. The ray that is deflected when the slope of the deflecting device is changed can in this way also arrive on reflecting surfaces 10 for the purpose of autocollimation, thereby enabling an improvement in measuring precision. Radiation emitted from the detector is periodically reflected back onto the detector to provide a reference signal.
