- the first drive unit and the second drive unit are designed as electric motors which are directly connected to the associated transmission input shafts within the individual partial transmissions.
- the above transmission-motor arrangement is preferably used in automated manual transmissions or automatic transmissions.
- the object of the invention can be achieved by a transmission-motor arrangement with two independently operable drive units and a manual transmission, with a transmission input shaft and a transmission output shaft, wherein the first drive unit with the transmission input shaft via a first clutch and a second drive unit with the transmission input shaft via a second clutch are connectable, and wherein a torque generated by the first drive unit and a torque generated by the second drive unit can be introduced independently into the common transmission input shaft and combined there to a total moment are.
- the transmission is provided with two inputs, which are each connected to a separate motor (combustion and / or electric motor), so that it is also possible in this embodiment to operate both motors alternately or simultaneously , Accordingly, in turn, the above consumption advantage can be realized.
- two small single clutches can be used for half the moment, so that effort / cost and space compared to the known crankshaft separation can be reduced.
- the above object is achieved procedural point of view by a method for operating a transmission-motor assembly in which the drive units at part load alternately or only one of the drive units is operated and the drive units are operated together at full load.

- the drive unit 11 can be connected via the clutch 12 to a transmission input shaft 16 of a second partial transmission 15.
- both partial transmissions 13, 15 of the powershift transmission via the clutches 11, 12, each with a drive machine 10, 11 connectable.
- combustion engines and / or electric motors can be provided as drive machines. If internal combustion engines are provided for both of the originally operable drive units, then they can have a common cooling circuit, whereby an operating temperature to be set can be ensured in a simple manner.
- an electric motor If an electric motor is already present, it can also be used as a starter for both internal combustion engines. If no electric motors are provided, then a starter motor can be arranged on one of the internal combustion engines and used as a starter for both internal combustion engines.
- clutches 11, 12 are provided as a prime mover or as engines internal combustion engines, so the use of the clutches 11, 12 is necessary, each of which may be formed as a single clutch.
