Verfahren und Einrichtung zum Erfassen von Fehlstellungen einer Kardanwellenanordnung

摘要

The method involves detecting fault points between drive (3.1) and driven (3.2) shafts of a propeller shaft arrangement (3), especially in a railway vehicle drive train, coupled to a 3-phase machine (2). A signal representing the degree of a fault position is determined by correlating a first signal characteristic of the rotary field of the 3-phase machine with a second signal characteristic of the rotary motion of the propeller shaft arrangement. Independent claims are also included for the following: (a) an arrangement for detecting fault points in a propeller shaft arrangement (b) and a railway vehicle with a three-phase machine and a drive device with a propeller shaft coupled to the machine.
