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.

Drive arrangement for a hybrid-drive motor vehicle

A multi-speed transmission for a motor vehicle, in particular for a sports car, has several forward speeds and a reverse speed, an input or primary shaft, a first output or secondary shaft for driving a first drive shaft leading to an axle differential, and a second output shaft or tertiary shaft for driving a second drive shaft leading to another axle differential. The first output or secondary shaft and the second output or tertiary shaft carry two meshing fixed gears. The fixed gear on the first output or secondary shaft meshes with an idle gear on the input or primary shaft. In one of the forward speeds the idle gear coupled in a rotationally restrained manner with the input or primary shaft directly drives the fixed gear on the first output or secondary shaft.

Multi-speed transmission

A 7-speed transmission for a motor vehicle, in particular for a sports car, includes an input or primary shaft, an output or secondary shaft, a first, a second, a third, a fourth, a fifth, a sixth and a seventh forward speed, as well as a reverse speed. In order to obtain a compact constructional design with a small transversal size and allow a sporty drive mode in the upshift from the first to the sixth speed, in which the shift process occur in an overlapping manner and almost without any interruption of the drive force, the eight speeds are combined in pairs into four shift groups, two of the four shift groups are arranged on the input or primary shaft and two on the output or secondary shaft, respectively, and at least between the first speed and the sixth speed adjacent speeds are arranged in different shift groups.
