Abstract
A drive train () of a motor vehicle has an internal combustion engine () with a crankshaft (). A transmission () is connected downstream for driving at least one axle () of the motor vehicle. A starter generator () is attached to the crankshaft () of the internal combustion engine () via a spur gear mechanism (). The spur gear mechanism () has a first drive train () with a switchable clutch () and a second drive train () with a switchable clutch or a freewheel () that is active during the starter mode of the starter generator (). In a drive train of this type, the components for transmitting the torque of the starter generator () require only little space and, during starting, the crankshaft () of the internal combustion engine is decoupled from tensile forces and weights which would be observed when a belt drive is used.
