Device for damping the squealing noise of a metal wheel in contact with a metal running surface

摘要

The device has a metal snap ring (11) mounted in a groove that is formed along inner radius of a rim of a metal wheel. The snap ring is formed as a single-piece part. A tightening system (20) is connected between two ends (11a, 11b) of the snap ring in the groove to ensure mechanical coupling of the ring and the metal wheel. Holes (12a, 12b) are formed in a body of the snap ring with respect to the ends of the snap ring. The tightening system comprises a rod (21) whose one end (21a) is inserted into one of the holes and another end (21b) is inserted into another hole.
