Disclosed is a multi-speed gearbox (10; 10a) comprising two input shafts (12, 13) and one output shaft (25). Each of the input shafts (12, 13) is connected to a clutch (29, 30) and can be separated with the clutch from the internal combustion engine (11) of a motor vehicle. One or two electric motors (34, 35; 40) are allocated to the two input shafts (12, 13) and joined thereto in non-positive fit. The electric motors are arranged on the opposite side of the clutches (29) to the internal combustion engine. The electric motor or motors (34, 35; 40) make(s) it possible to do without a starter and a dynamo for the internal combustion engine (11). The synchronisation speed of the input shaft (12, 13), corresponding to a target gear, can be adjusted in a simple manner, enabling various operating states to be obtained. |
