  • Drive train for a hybrid vehicle, in particular for a temporarily four wheel driven motor vehicle
    Patent number: 11167634
    Abstract: A drive train for a hybrid vehicle, in particular for a temporarily four-wheel-driven motor vehicle, wherein the drive train comprises a first partial drive train assigned to a primary axle and a second partial drive train assigned to a secondary axle, and wherein the first partial drive train comprises a first drive unit configured as an internal combustion engine and a second drive unit configured as an electric machine and a change transmission, is refined in that the hybrid drive train is inexpensive to produce, has low CO2 emissions in operation, and may be used in a drive train of a temporarily four-wheel-driven motor vehicle.
