Abstract
A hybrid drive for a vehicle in which the driving power provided by an internal combustion engine (ICE) or an electric motor may be fed via a transmission with a transmission input shaft and a transmission output shaft to the drive train. The ICE and the electric motor are connectable to each other via a coupling and the electric motor is directly connected to the transmission. An electric energy storage device is connected to the ICE for receiving a charge and to the electric motor for providing power to the electric motor. The hybrid drive is designed so that the torque that can be provided by the electric motor is greater than that of the internal combustion engine. In addition, the transmission input shaft always turns in the same direction as the transmission output shaft so that reverse drive by the hybrid drive is only possible using the electric motor.
