1. A powertrain for a work machine, the powertrain comprising:
a first electric motor;
a first drive shaft being concentrically aligned with and drivable by the first electric motor;
a second electric motor;
a second drive shaft being concentrically aligned with and drivable by the second electric motor;
a first coupling gearwheel fixedly connected to the first drive shaft;
a second coupling gearwheel configured as an idler gearwheel and connectable in terms of drive to the second drive shaft by means of a coupling element;
a first clutch configured for interrupting a power flow in the first drive shaft, the first clutch connected downstream of the first coupling gearwheel in terms of drive; and
a second clutch, for interrupting a power flow in the second drive shaft, connected downstream of the second coupling gearwheel in terms of drive;
wherein the first coupling gearwheel directly engages with the second coupling gearwheel.
