Abstract
A hybrid drive for a vehicle includes an electric engine supplied with energy from an electrical storage device and capable of returning energy back to the storage device. The electric engine is connected with a driving axle of the vehicle by a first disconnecting clutch and to an internal combustion engine arranged in series therewith by a second disconnecting clutch. Operation of these clutches can be independent of each other. In order to save fuel the internal combustion engine is not supplied with a dedicated flywheel, but instead utilizes the rotating masses of the drive between the disconnection points of the two clutches, e.g., the rotating elements of the electric engine, as a flywheel.
