Drive System

A drive system for driving or being driven by a machine coupled with the drive system, the drive system comprising:

• an output configured for at least one of driving or being driven by the coupled machine;
• a first machine unit comprising at least one first electric machine for at least one of driving or being driven by the output;
• and
• a second machine unit comprising at least one second electric machine for at least one of driving or being driven by the output;
• wherein at least one of:
• a) the first machine unit comprises a transmission gear arranged to at least one of be driven by the first electric machine or to drive the first electric machine, and the drive system comprises a first switching device configured such that:
• in a first operating state of the first switching device, the transmission gear of the first machine unit and the output are operatively mechanically connected in a torque-transmitting manner, and
• in a second operating state of the first switching device, the operative connection between the transmission gear of the first machine unit and the output is interrupted;
• or
• b) the drive system has a second switching device configured such that:
• in a first operating state of the second switching device, one of the first or second electric machines and at least one of a power supply or an energy storage device are electrically connected, and
• in a second operating state of the second switching device, the connection to the at least one of a power supply or an energy storage device is electrically disconnected and an active short-circuit of the first or second electric machines is effected.
