FIELD: transport.
SUBSTANCE: invention relates to earthmovers with hydrostatic transmission. Earthmover consists of ICE, fluid pumps and hydraulic motors with final drives, working equipment hydraulic drive, electrical or hydraulic power accumulator connected via hydraulic unit or electrical switch with transmission or working hardware fluid lines or with electric circuits of at least one motor, generator or motor-generator. Power exchange between power accumulator and transmission, ICE and working hardware hydraulic system is controlled by electronic module.
EFFECT: stabilised ICE operation, accelerated operation under non-optimised conditions, decreased rpm dispersion, higher efficiency and fuel savings.
