IMPROVEMENT OF WORKING CONDITIONS OF THE FREIGHT LOCOMOTIVE RUNNING GEAR

Abstract

To improve the working conditions of the electric locomotive running part, it is necessary to decrease unsprung masses, lateral loads and the angle of attack and provide the third body with proper tribotechnical properties. A new scheme of the freight electric locomotive running gear is elaborated in the work, which ensures a decrease of unsprung masses, relative sliding of a wheel on the rail and an angle of attack that provides resistance to the destruction of the third body in the contact zone.
