Abstract

A drive train for a motor vehicle, having a drive unit which comprises a prime mover, a multi-step transmission and a power-splitting device which distributes the driving power between a first and a second drive shaft of a driven axle. The transmission comprises a transmission input and a first sub-transmission and a second sub-transmission. The prime mover is directly connected to the transmission input, wherein each of the two drive shafts is assigned a first and a second friction clutch. The first friction clutches connect the respective drive shaft to the first sub-transmission. The second friction clutches connect the respective drive shaft to the second sub-transmission. The first friction clutches and the second friction clutches form the power-splitting device.
