Abstract
A drive train (1) of a purely electrically all-wheel drivable motor vehicle has a first axle (2) having a differential (23), a second axle (3) having a differential (26), and at least one electric machine (11, 32) for driving the two axles (2, 3). The at least one electric machine (11, 32) is arranged transversely to the direction of travel (4) of the motor vehicle and is connected to the first axle (2) of the drive train (1) via a spur gear (12). The first axle (2) and the second axle (3) each have a crown wheel (25). The crown wheels (25) are connected to each other via a shaft (27) that has pinions (28) at its respective ends, which engage into a respective crown wheel (25). The drive train allows retrofitting the drive train with simple construction, from an initial state with only one driven axle to all-wheel drive.
