The reduced wear of wheel pair flanges of freight cars

Abstract

Reduced wear of rails and wheels of rolling stock is a very important task of railway transport. Solving this problem not only in-creases the lifespan of wheels and rails, but often leads to a positive reduction of fuel consumption for train traction, reduces noise when the train moves in curves. The intensity of wear of rails and wheels of rolling stock depends on many factors. The practice of Ulan Bator railway shows that since 1992, the flange of the wheels has started to wear out intensively, thereby increasing operating costs to repair and reducing service life of the railcar wheel pairs. In order to determine comprehensive measures for the rotation of wheel pairs as well as to determine the intensity of wear of the flange thickness of railcar wheel pairs, experiments have been con-ducted on the wear and turning of wheel pairs of freight cars. To substantiate comprehensive measures for the rotation of wheel pairs and determine the intensity of wear of the flange thickness of the railcar wheel pairs, experimental tests on a freight car after the overhaul with the 33-mm flange thickness have been carried out throughout the year.
