Claim:
1. A drive train of an all-electrically drivable motor vehicle, comprising: a first axle with a first differential, a second axle with a second differential, first and second electric machines provided respectively with first and second driven shafts that are coaxial with one another and substantially parallel to the first and second axles, a gear mechanism arranged so that the first and second electric machines can drive the first axle and a switchable clutch arranged between the second electric machine and the gear mechanism so that the second electric machine can be decoupled from the gear mechanism, the first and second differentials being provided respectively with first and second differential housings formed respectively with first and second ring gears thereon, the first and second ring gears being connected to one another by a shaft for all-wheel operation of the motor vehicle, the shaft having a controllable clutch between the first differential and the second differential for selectively disconnecting the second axle from the gear mechanism and the electric machines, whereby selective operation of the switchable clutch and the controllable clutch enables the first electric machine to drive one or both of the axles and enables both of the electric machines to drive one or both of the axles.
