Abstract
A drive unit for an electric vehicle has at least one electric machine, a multi-speed transmission, and a distributor device. The rotor of each electric machine is connected to an associated input shaft of the multi-speed transmission. The multi-speed transmission is connected on the output side to the distributor device with different transmission ratios being selectable in the multi-speed transmission. In addition, a drive power introduced into the distributor device can be distributed to at least two outputs of the distributor device. In order to provide a compact drive unit for an electric vehicle with permanent all-wheel drive or selectable all-wheel drive, the distributor device can be used to provide a longitudinal distribution of the introduced drive power in that the outputs of the distributor device are each provided for coupling to a respective drive axle of the electric vehicle.
