Protsiv V. Scientific ground of technical decisions on perfection of the brake system of the mine joint-joined locomotive

Dissertation is devoted to the questions of increasing efficiency of mining lo-comotives brake systems foremost for heavy joint-joined one. Actual scientific matter about determination of regularity for the law of dynamic parameters for mining trains braking process is decided. Source data contains a different values of real curvatures and imperfections of mining rail way, those during development of new technical de-cisions provides diminishing either mining train brake distance, safety stop and stand, and standing on the longitudinal slopes of the way by a value up to 50%o. Calculations those take into account a simultaneous and by turn braking of joint-joined locomotive with trainload by shoe-wheeled, axial and transmission disk brakes, and dynamic braking by engine, both magnetic and gravity brakes are made. Developed and approved dynamic model of mining joint-joined locomotive with trainload by devices with limited friction moment and rail brakes on the real rail way with either systematic and local, long and short imperfections. Influence of real mining rail way imperfections is researched on a maximally possible brake moment and mining joint-joined locomotive with trainload braking distance by the devices those realize braking force in a point of contact either wheel and rail, and rail brakes. Developed and approved algorithm of mining locomotive device for automatic control of wheel scuffing.
