DRIVE ARRANGEMENT FOR A HYBRID-DRIVE MOTOR VEHICLE

摘要

The invention relates to a drive arrangement for a hybrid-drive motor vehicle, having 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 being able to be uncoupled by means of a disconnecting clutch. To allow a drive arrangement of simple construction and good efficiency to be obtained, it is proposed that the gearbox be divided into two sub-gearboxes (3, 4) which preferably each have at least two gear ratios, with the internal combustion engine (2) being connected for drive to the first sub-gearbox (3), i.e. in such a way as not to be able to be uncoupled. The electrical machine (6) is also arranged, in the path along which force is transmitted, downstream of the disconnecting clutch (5) arranged at the output (8) of the first sub-gearbox (3) but upstream of the second sub-gearbox (4), and the output (11) of the second sub-gearbox (4) provides an output drive to the axle differential (7).
