  • Hybrid drive for a vehicle
    Patent number: 9254737
    Abstract: A hybrid drive of a motor vehicle includes a combustion engine, an electric machine, a gear box, and a superimposed transmission. The gearbox includes an input shaft, and first and second output shafts, and the input shaft is connected to the first and second output shafts via switchable spur gear stages. The superimposed transmission is connected non-rotatably to a hollow shaft arranged coaxially with the second output shaft. The hollow shaft is connected non-rotatably to an idler of an axially adjacent switchable spur gear stage via a first coupling-switching element, and the hollow shaft is fixed at a housing via an interlock switching device. A bridging contact member connects the hollow shaft to the superimposed transmission, and the superimposed transmission is also permanently connected to a rotor of the electric machine.
