Patent ID: 8398523

Claim:
A drivetrain for an all-wheel-drive vehicle which has a first driven axle and a second driven axle, having a drive unit which is connected on one axial end to a multi-stage transmission which has a multiplicity of gear stages for generating different transmission ratios, with a transmission output shaft of the multi-stage transmission being connected to the first driven axle, with the drive unit being connected on its opposite axial end to an activating arrangement, wherein an output element of the activating arrangement is connected to the second driven axle, such that drive power can be supplied to the first axle permanently via the multi-stage transmission and drive power can be supplied to the second axle on demand via the activating arrangement, wherein the activating arrangement has a first activating friction clutch and a second activating friction clutch which are designed to supply drive power to the second axle via a first and a second transmission ratio stage respectively, with the first transmission ratio stage being assigned to at least one lower gear stage of the multi-stage transmission and with the second transmission ratio stage being assigned to at least one higher gear stage of the multi-stage transmission and wherein the activating arrangement has a third activating friction clutch which is designed to supply drive power to the second axle in the opposite rotational direction.
