HYDRAULIC DRIVE Russian patent published in 2000 - IPC

Abstract RU 2156391 C2

FIELD: mechanical engineering. SUBSTANCE: hydraulic drive is designed to control speed of working members of building, road and other machines. Hydraulic drive provides for four modes of operation: "sums" mode when shafts rotate in one and the same direction, mode of counterrotation of shafts and two modes of operation of one of hydraulic machines with simultaneous interlocking of other hydraulic machine. Hydraulic drive is changed over from one mode to another without stopping of hydraulic transmission. EFFECT: enhanced efficiency and reliability. 1 dwg
