Abstract

Hydro-drive of excavator includes pumps, pressure and discharge mains, executive hydraulic motors, hydraulic distributor connected to executive hydraulic motors, power controller that consists of body in which spring-supported piston is placed, and additional hydraulic cylinder that has cavity with floating piston, at its one side pusher is placed, this kinematically interacts with the last one and with spring-supported piston, and servo-system with source of constant pressure. Hydraulic drive is equipped with source of varying pressure. Servo-system is arranged of source of supplementary pressure with independent drive and hydro-line for supply of supplementary pressure, this by means of valve “OR” is connected to the cavity of additional hydraulic cylinder at side opposite to pusher.
