Pavlenko A. Dynamic and heightening cohesion-traction of qualities of driving of locomotivs

The thesis devote to problems of a heightening cohesion-traction and improving of dynamic qualities of driving of locomotivs at the expense of making and implantation more affective anti-slippage systems. Radically new approach to designing anti-boxing systems has been worked out and put into effect, which is based on using peculasities of dynamic processes in tractive drive which have been defected in this work. The most important of which is automatic alteration of subsystems of angular oscillations of drive units at the moment of reaching by wheel pairs the limiting forces of their ganging the rails. On the basis of indicated property the comprehensive system of detection of limiting cohesive forces of rail vehicles has been designed. The designed system allows to notify a possible development of slippage without lowering the tractive moment of wheel pairs.
