摘要

A hydraulic operation system, especially for an automated gearbox, like an auto gearbox system or an automated clutch of a car with a drive engine, has pump devices. The pump device is designed so that it is connected in force-transmitting fashion to a drive engine or gearbox of the vehicle via a mechanical drive and via a freewheel mechanism. The pump device can additionally be connected to an electric motor, still in force-transmitting fashion. The mechanical drive and the electric motor are connected to a drive shaft of the pump device at opposite sides or ends of the shaft or pump device.
