Abstract: An all-wheel drivetrain for a motor vehicle, which has at least two driven axles, comprising a characteristic torque converter transmission of longitudinal construction. To the input side of the transmission drive power is fed and the transmission serves for converting a characteristic of a drive engine. The output side of the transmission is connected to a transfer device, by means of which the drive power can be distributed to the two axles. The transmission has an output shaft which is connected to a first drive shaft for the first axle, and a countershaft parallel thereto. The output shaft and the countershaft are connected to one another by means of a first constant transmission ratio. The countershaft is connected by means of a second constant transmission ratio to a second drive shaft for the second axle. The transfer device is arranged coaxially with the second drive shaft.

The input shaft extends in a longitudinal direction. The drive unit comprises a power-split device, of which the input member is connected to the input element and of which the output members are connectable to driveshafts of the axle. The axle is oriented in a direction transverse to the longitudinal direction. The input member and the output members of the power-split device are mounted rotatably about axes parallel to the longitudinal direction. An angle drive is arranged in each case between the output members of the power-split device and the driveshafts.

Abstract: The invention relates to an asymmetrical, active axle transmission with an epicyclic gear system, which is arranged concentrically to a side shaft (7) and has a planet carrier (17). To achieve an active yaw function, the planet carrier (17) or the central wheel (13) can be braked. Conventional asymmetrical active yaw gears use in this connection two separate brake clutches. This enlarges the construction space and increases the manufacturing costs which the invention avoids in that the planet carrier (17) is part of a first brake coupling (5) and that a second brake clutch (9) for braking the side shaft (7) as well as the first brake clutch (5) use a common abutment lamella (19).

The input members of said friction clutches are connected to the output of the drive unit. The output members of said friction clutches being connected respectively to a left and to a right driveshaft of the front axle.
