HYBRID DRIVE FOR A TRANSPORTATION MEANS

The invention relates to a hybrid drive of a vehicle comprising a storage device for mechanical energy, whose shaft is connected to the carrier of a planetary mechanism, as well as to an energy storage device electrically connected via a control system with reversible electric machines, wherein at least one of the electric machines is mechanically connected to a central gear of the planetary mechanism and a second central gear of the planetary mechanism is mechanically connected to a differential of the drive wheels of the vehicle. The torque transmitted to the drive wheels and the drive efficiency can thereby be increased in that the said electric machine is designed with two rotatable parts which are mechanically connected to the central gears of the planetary mechanism and that additionally two controllable clutches are provided for connecting the said rotatable parts of the reversible electric machine to one another and for connecting the carrier of the planetary mechanism to a stationary drive element or the housing.
