  • Electric drive train for a vehicle
    Patent number: 4484083
    Abstract: A transmission drive has a flywheel component and includes an electrical machine in the transmission path having an armature adapted for independent rotation with the driving side of the transmission drive and an independently rotatable field structure rotatable with the driven side of the transmission drive. In a vehicle drive train the field structure of the transmission drive is connected to a rotatable shaft driven by a heat engine operated at constant RPM and speed variation is effected by electrical control means connected to the armature which regulates the armature current during relative movement of the field structure and the armature thereby varying the power transmitted to the driving side.
