METHOD OF NOISE SUPPRESSION AT THE INTERACTION OF WORKING BODIES OF WAGON MODELS WITH LATER SURFACES OF WHEELS OF CARGO WAGONS

摘要

FIELD: transport machine building.SUBSTANCE: invention relates to the field of transport machine building. Method of noise reduction in the interaction of the friction surfaces of the beam wagon retarders with the side surfaces of the wheels of freight cars, based on the modification of friction surfaces with soft metals with the possibility of contacting materials, the friction surfaces are made thereof, is that the modification process is carried out by feeding a noise-suppressing cladding material from cavities that are in one of the bodies of the friction pair when the body is worn during the contacting process with the second body of the friction pair.EFFECT: improved noise reduction between friction surfaces.1 cl, 3 dwg
