摘要： The present invention relates to a hydraulic unit with a housing in which a hydraulic converter is accommodated, which is coupled with a drive shaft that includes a connecting shaft piece located outside the housing for connection to a mechanical drive element The invention furthermore relates to a hydraulic driving device with such hydraulic unit and to a drive train connecting piece to which the hydraulic unit is connected.It is proposed to integrate a clutch for connecting and disconnecting the hydraulic unit into the hydraulic unit itself, so that a mechanical drive train, to which the hydraulic unit is connected, can remain unchanged or need not especially be adapted to the clutch. In accordance with the invention, a clutch for coupling and uncoupling the connecting shaft piece of the hydraulic unit to and from the hydraulic converter of the hydraulic unit is accommodated in the housing of the hydraulic unit.

摘要： The present invention relates in general to working machines with working units which are subject to fluctuating loads or have a fluctuating power consumption. The invention relates in particular to a drive train assembly for driving such a working unit, the drive train assembly having a flywheel accumulator for mitigating the load impacts or load fluctuations. According to the invention, a starting aid for easier starting up of the flywheel accumulator into its desired operating speed range is provided, the starting aid having a planetary transmission, which is connected in terms of drive to the flywheel accumulator, and a control actuator for braking and/or accelerating a planetary transmission element in order to adjust the step-up/step-down ratio of the planetary transmission when starting up the flywheel accumulator. Furthermore, for refined smoothing of the power consumption in the started-up working mode, a control device is provided which accelerates and can brake the flywheel accumulator cyclically by adjusting the planetary transmission in accordance with the operating fluctuations of the working unit.
