Abstract: A drive arrangement for a hybrid-drive motor vehicle includes an internal combustion engine and at least one electrical machine which, via a speed-change gearbox having a plurality of gear ratios, provide, alternately or together, an output drive to at least one axle differential of the motor vehicle. The internal combustion engine can be uncoupled by a disconnecting clutch. The gearbox is divided into two sub-gearboxes, with the internal combustion engine being connected for drive to the first sub-gearbox such as not to be able to be uncoupled. The electrical machine is arranged, in the path along which force is transmitted, downstream of the disconnecting clutch arranged at the output of the first sub-gearbox but upstream of the second sub-gearbox. The output of the second sub-gearbox provides an output drive to the axle differential.
