Estimating the term…
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.

A method of operating a drive train, wherein the drive train comprises a drive unit and a transmission having a first and a second sub-transmission, wherein a first friction clutch is assigned to the first sub-transmission and wherein a second friction clutch is assigned to the second sub-transmission, wherein both sub-transmissions comprise a starting gear ratio with the same transmission ratio, wherein starting is achieved by simultaneously engaging the first and the second friction clutch.
The method of operating a drive train, wherein the drive train comprises a drive unit, a transmission having a first and a second sub-transmission and also a driven axle having a first drive shaft and a second drive shaft, wherein a first and a second friction clutch are assigned to each of the two drive shafts, wherein the first friction clutches connect the respective drive shaft to the first sub-transmission and wherein the second friction clutches connect the respective drive shaft to the second sub-transmission, with the step of connecting the one drive shaft via the first friction clutch and the first sub-transmission to the drive unit and connecting the other drive shaft via the second friction clutch and the second sub-transmission to the drive unit when cornering.
