- Abstract
The railway vehicles are characterized by the fact that the wheel axle moves in the path of travel and self guidance in the contact forces between the tire rim and wheel tracks. Following wheels, besides the three common features they have and other land vehicles, namely support vehicle vertically, running about and propulsion, respectively braking railway vehicles in addition their specific function, namely self guidance that the two wires inside of rail. Being metallic wheels and also the rails that give the vehicle the ability to rail loadings much higher than other land vehicles. This capability, combined with that of self guidance, creates the possibility of forming convoys of vehicles (trains) heavy, giving wheel system - advantages of high capacity rail transport. The study and thorough understanding of the complex phenomena of the contact wheel - rail is actually the fundamental problem that ensures the development of railway vehicles.
