Abstract: Generally, kinetic energy in the locomotive braking is converted into heat that is transmitted to the bandage. Because of overloading of the bandaged wheels the phenomena of bandages weakening combined with tread defects appears. This danger exists especially when train brakes on long slopes and with high gradients. The decisive effect on the frictional and wear characteristics of the brake system is exerted by temperature generated at friction.
Keywords: braking process, thermal stress, friction coefficient, wheels with bandages.
EXTENSION of the file: .doc
