Selected damage and wear of wheelsets of rail vehicles

Abstract

The article presents examples of wear and damage to wheelsets of rail vehicles. In addition to wheel and axle defects that are diagnosed during daily diagnostic service, fretting wear is indicated, which develops in a press-fit wheel-axle. This type of wear is difficult to recognize and contributes to the development of fatigue consumption, which can lead to axle breakage or loose connection, resulting in the derailment of the vehicle.
