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. |

1. A hybrid drive of a motor vehicle, comprising:
a combustion engine with a drive shaft; an electric machine with a rotor configured to operate as a motor or a generator; an automated gearbox comprising an input shaft and at least one output shaft, the input shaft connected to said at least one output shaft via multiple selectively switchable spur gear stages; and a superimposed transmission comprising a first and second input elements, and an output element, the first input element connected non-rotatably to a first hollow shaft arranged coaxially with said at least one output shaft, wherein the input shaft is connected via a controllable decoupler or directly to the drive shaft, and the superimposed transmission is arranged coaxially with a free end of said at least one output shaft, wherein the first hollow shaft is connected non-rotatably to an idler of a directly adjacent axial spur gear stage via a first coupling-switching element, and the first hollow shaft is fixed at a housing via an interlock switching device, and via a bridging contact member the first hollow shaft is connected non-rotatably to the second input element or to the output element, wherein the second input element of the superimposed transmission is permanently connected to the rotor of the electric machine, and the output element of the superimposed transmission is connected non-rotatably to said at least one output shaft, and wherein the input shaft of the gearbox is connected to the second input element of the superimposed transmission via a coupler spur gear stage, the coupler spur gear stage comprising a drive gear and an output gear, and the coupler spur gear stage switched by means of a second coupling-switching element. |
