Abstract

Summary. The issue of environmental safety, from the perspective of increasing consumption of hydrocarbon energy sources, is of particular relevance.  In this regard  the use of  machines and  equipment  with high indicators of  fuel efficiency  and environmental safety  as well as  modernization of  machines  in service  is one  of the most effective  means of improving  the current  fuel and  energy and  environmental  situation.  The  strategy  of  developing  hybrid  drives  for  earthmoving  machines  on  the  example  of  the  world’s leading  equipment manufacturer has been considered.  The analysis of the  structural  performance of  the  power drive  as a whole and its  individual  elements,  interaction  of  power  unit  components  at  different  operation  modes,  principles  of  control  providing  for reduction of heat  consumption and  emissions of harmful  substances with exhaust gases has been carried out.  The aim  of the work  is determining the necessary adjusting power for engines of earthmoving machines considering the use of pumped storage  systems and systematization of  energy consumption  in their  working cycle  by developing a  methodology and  means for studying  the machine energy system. A strategy for creating hybrid drives for earthmoving machines has been defined.
