The ICE drives a DC generator which “stator” and
rotor can rotate separately. The “stator” is firmly
coupled with the ICE shaft. The rotor is coupled with
car wheels. On the car shaft is mounted a DC electric
traction motor supplied by the voltage induced in the
generator. The splitting is performed in the generator.
The relative speed between generator “stator” and
rotor is difference between the ICE and car speeds.
This solution allows split the ICE output into two
parts.
