摘要
An electrohydrostatic actuator system comprising: a volume and / or speed-variable hydraulic machine driven by an electric motor, for providing a volume flow of a hydraulic fluid; a differential cylinder with a piston side and a ring side, and at least one biasing source. The actuator system has a closed hydraulic circuit, the hydraulic fluid in the hydraulic circuit being pressurized during operation by means of the hydraulic machine and / or the preload source. Furthermore, according to the invention, the differential cylinder provides the operating modes of a power gear and a rapid gear. To compensate for a volume of hydraulic fluid in the closed hydraulic circuit, a suction tank is connected to the piston side of the differential cylinder via a valve.
