Abstract
The object to create a system and a method which allows better running gear diagnosis of rail vehicles is achieved by the present invention by arranging a number of force measurement devices on the rail measurement zone to detect the forces and/or torques acting on the rail measurement zone, such that the system also comprises a number of sonic measurement devices for detecting the sound waves which occur when the rail vehicle travels over the rail measurement zone. The present invention thus offers a diagnostic system for analysis of the condition of wheel bearings and wheel geometries in particular in which the forces and sound waves occurring when the rail vehicle travels over the rail can be detected and analyzed, so that more reliable inferences about the condition of the running gear of the rail vehicle can be drawn from them.
