DESIGN FEATURES OF FREIGHT CAR TRUCKS WITH CASSETTE-TYPE BEARINGS AND RESULTS OF COMPARATIVE TESTS OF VARIOUS BOX UNITS UNDER OPERATING CONDITIONS
Abstract and keywords
Abstract (English):
The paper presents the results of assessing the impact of installing wheelsets equipped with cassette-type bearings and adapters in freight car trucks. Variants of box unit designs with various types of bearings are considered. Geometrics of adapters from various manufacturers are analyzed. The analysis of the results of running dynamic tests conducted on a long-distance track shows a decrease in the maximum values of frame forces for cars equipped with cassette-type bearings with adapters up to 8%.

Keywords:
