Abstract
A drive train (1) of a purely electrically all-wheel drivable motor vehicle, has a first axle (2), a second axle and two electric machines (10) arranged in the direction of travel (3) of the motor vehicle. The first axle (2) can be driven by the electric machines (10) via a transmission (11). The transmission (11) and the first axle (2) are connected to each other by at least one bevel gear toothing (20, 7; 20, 27), and the transmission (11) and a shaft for driving the second axle are connected to each other by at least a further toothing (22, 23; 22, 28). In this way, an all-wheel drive can be achieved with a simple construction by the use of such a drive train in a motor vehicle that is to be operated in a purely electrical manner.
