Zusammenfassung:FIELD: construction engineering and mining machinery. ^ SUBSTANCE: invention relates to drives of cyclic action machines. Propose hydraulic drive includes power motor, flywheel, pumping set, hydraulic motor regulated to "p=Const", hydraulic motors of actuating mechanisms valves "OR" installed between pressure and drain main lines of hydraulic motors of actuating mechanisms, distributing equipment and tank. Pumping set is made two-section. Shaft of one section of pumping set is mechanically coupled with shaft of power motor, and shaft of other section is mechanically coupled with shaft of hydraulic motor and flywheel, and flywheel is coupled with shaft of motor by overrunning clutch. ^ EFFECT: improved reliability and economy of drive owing to provision of constant loading of motor. ^ 1 dwg
