DRIVE TRAIN FOR A HYBRID VEHICLE, IN PARTICULAR FOR A TEMPORARILY FOUR WHEEL DRIVEN MOTOR VEHICLE

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. This is achieved in that change transmission comprises an input shaft and an output shaft, wherein the first drive unit is coupled to the primary axle via the change transmission, and wherein the second drive unit is coupled to the primary axle via the input or output shaft of the change transmission, and wherein the drive train furthermore comprises a clutch arrangement, wherein the secondary axle can be coupled in a driving manner to the primary axle by means of the clutch arrangement.
