Method for automatically determining wheel diameter or wheel shape of rail vehicle wheel, using measurement beam arrangement so that wheel sizes and shapes can be accurately accessed and compared

At least one wheel (2) of a wheel set is moved along a measurement stretch with a measurement slit (6) parallel to the wheel. A measurement beam (LS) is directed at the wheel surface (21) from the slit. The reflected beam is detected and from it the separation (m, n) to the wheel running surface (21...

Zusammenfassung:	At least one wheel (2) of a wheel set is moved along a measurement stretch with a measurement slit (6) parallel to the wheel. A measurement beam (LS) is directed at the wheel surface (21) from the slit. The reflected beam is detected and from it the separation (m, n) to the wheel running surface (21) is determined. From the measured or calculated relative position of the wheel and slit a partial radius (r1, r2) of the wheel is determined. AN Independent claim is made for a corresponding measurement device. Bei einem Verfahren zur Bestimmung des Raddurchmessers und/oder Radprofils von Schienenfahrzeugrädern wird ein Messschlitten (6) parallel zu mindestens einem Rad (2) eines über eine Messstrecke bewegten Radsatzes bewegt. Vom Messschlitten (6) wird mindestens ein Messstrahl (LS) auf die Radlauffläche (21) des zu vermessenden Rades (2) gerichtet, der reflektierte Messstrahl (LS) erfasst und daraus die Entfernung (m, n) zur Radlauffläche (21) des vermessenden Rades (2) ermittelt. Aus einer erfassten und/oder berechneten Relativposition des zu messenden Rades (2) und des Messschlittens (6) wird zumindest ein Teilradius (r¶1¶, r¶2¶) des vermessenden Rades (2) bestimmt.
