Failure analysis on rubber universal spherical joints for rail vehicles
Source abstract
Abstract
Abstract Considering the large quantity of passengers in a running rail vehicle, its safety must be paid special attention to, which relies on the reliability of every critical component. Spherical universal joint is widely used in the suspension device of the gearbox in the transmission of railway vehicles for its functions of damping and cushioning. Since it’s commonly made of rubbers rather than the familiar metallic materials, its degradation behaviors and failure mechanisms have not been systematically investigated. In this study, multiple rubber spherical universal joints used in the urban rail transit train were found cracked and sticky during maintenance. Its design lifetime was 5 years, but this kind of failure occurred in
