Abstract

A drive arrangement for a motor vehicle, having an internal combustion engine with a crankshaft which can be connected, via an interposed clutch, to a gearbox input shaft of a change-speed gearbox, and having an electric machine—for example an electric motor or a starter-generator—which is provided in the drive arrangement and which has a stator and a rotor. The electric machine, in order to step down its rotational speed, is operatively connected to the crankshaft and/or the gearbox input shaft via a step-down gear mechanism. The step-down gear mechanism is designed as an epicyclic gear mechanism, which has a sun gear, an internal gear and a number of planet gears. The epicyclic gear mechanism can be switched or clutch-operated via two clutches.
