The invention concerns a drive system for the transmission of power from a drive source to a plurality of output trains, the drive system comprising a transfer gear connected upstream of the output trains, and an arrangement for ensuring that the output trains are not overloaded with torque. The arrangement comprises a safety clutch (9) with a basic clutch body for the frictionally engaged connection of two machine parts, and at least one thin-walled sleeve (12) which forms a wall (13) of an annular chamber (14) upon which pressure medium can act. The arrangement further comprises at least one feed line (28) which extends through the clutch body to the annular chamber and can be closed off in an air- and fluid-tight manner by means of closure elements (50). The arrangement finally comprises a pressure-relief mechanism (31). According to the invention, the safety clutch is arranged upstream of the transfer gear. The pressure-relief mechanism (31) is coupled to an arrangement for detecting the torque at the output trains and/or a magnitude which is proportional to the torque and is associated with each output train, and/or a influencing quantity in the area surrounding the machine. The clutch comprises means for activating the pressure-relief mechanism (31) when the torque and/or a magnitude proportional to the torque and/or an influencing quantity is/are exceeded. |
