FEASIBILITY OF TECHNICAL REQUIREMENTS FOR FRICTION ACTIVATORS IN CONTACT ZONE "WHEEL - RAIL"
While developing technical requirements, the questions of application the friction promoters and modifiers were considered from the solution of the steering friction problem in the wheel rail system. Modern approach of regulation the processes of friction and clutch in a zone of contact piece of a bandage of a wheel to a head of a rail is based on the concept of steering friction due to version of contact areas of wheels and rails by special materials - the friction promoters and modifiers. The friction modifiers intended for use in the wheel rail system are materials which are added to the contact area of the using wheel and rail surface for the purpose to create the third body having desirable properties. The friction promoter is material that is adjustable increasing force of the locomotive wheel adhesion with rails to the level providing steady realization of locomotive tractive effort on clutch.
