Technical solutions to extend the service life of solid roll wheels of passenger carries

Abstract

Rail transport plays an important role in the economy. This especially applies to passenger transportation, in particular in the Republic of Uzbekistan, where the problem of passenger rail transport is very acute. The fact is that passenger cars in Uzbekistan are mainly purchased from other countries. The volumes of our own production are very limited and most often consist of major repairs of cars produced in the 40-60s of the last century. This paper presents the results of studies that ensure the safety of passenger transportation by extending the service life of the wheel pairs of the corresponding cars.
