Drive train assembly for driving a working unit with a fluctuating load

A drive train assembly for driving a working unit with fluctuating power consumption from a drive source comprising:

• a flywheel accumulator for mitigating load impacts and/or power consumption fluctuations,
• a starting aid comprising a planetary transmission having at least one planetary transmission stage drive-connected to the flywheel accumulator, wherein the starting aid is configured to start up the flywheel accumulator into a desired speed range, and wherein the starting aid further comprises a drive and/or brake actuator for braking and/or accelerating a planetary transmission element in order to adjust a step-up/step-down ratio of the at least one planetary transmission stage when starting up the flywheel accumulator into its desired operating speed range, wherein the drive and/or brake actuator comprises a hydraulic or electrical motor for braking and/or accelerating the planetary transmission element, wherein when starting up the flywheel accumulator, the motor of the drive and/or brake actuator is configured to operate as a brake motor and/or is configured as a pure brake motor;
• and
• a planetary web stationarily connected to a stationary housing.
