Abstract
A drivetrain for a vehicle includes a first electric machine, an input shaft connected to the first electric machine, an output shaft, an energy store connected to the first electric machine, and a magnetic-electrical epicyclic transmission stage having a rotor connected to the input shaft, a stator, and an interposed modulation ring connected to the output shaft. The energy store is connected to the stator such that electrical power can be transmitted from the energy store to the stator, which is operable such that the output shaft is rotatable counter to the direction of rotation of the input shaft, such that the drivetrain can be operated in a forward and a reverse traction mode.

A drivetrain for a vehicle, comprising:
- a first electric machine;
- an input shaft connected to the first electric machine;
- an output shaft;
- an energy store connected to the first electric machine;
- and
- a magnetic-electrical epicyclic transmission stage including a rotor connected to the input shaft, a stator, and an interposed modulation ring connected to the output shaft;
