Drive system for the transmission of power from a power source to a plurality of output trains

A drive system for transferring power in a direction of power transfer from a power source, said drive system comprising:

• a plurality of power take-off drivetrains;
• a transfer gearbox disposed upstream from said drivetrains relative to the direction of power transfer;
• a control device configured for processing an acquired value of at least one of a torque on said power take-off drivetrains, a value proportional to the torque which is assigned to each said power take-off drivetrain, and a disturbance value, said disturbance value quantifying a disturbance originating nearby;
• and
• a protection device configured for protecting against a torque overload condition in at least one of said drivetrains, said protection device including a single safety coupling disposed upstream from said transfer gearbox relative to the direction of power transfer, said safety coupling having:
• a relief mechanism connected to said control device;
• an activating device configured for activating said relief mechanism upon at least one of the torque, the value proportional to the torque, and the disturbance value being exceeded;
• and
• a coupling body configured for achieving a non-positive connection between two machine components, said coupling body being configured to limit thereto deformations needed to achieve the non-positive connection and to thereby avoid deformations to said two machine components, said coupling body including at least one thin-walled sleeve partially defining a ring-shaped pressurizable chamber, said coupling body also including at least one supply drilling extending through said coupling body to said ring-shaped chamber, said at least one supply drilling being configured for being sealed with sealing valves in a fluid-tight manner.
