The invention relates to a drive train (1) of a purely electrically all-wheel drivable motor vehicle, comprising 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). In such a drive train it is provided according to the invention that 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), and the first axle (2) and the second axle (3) each comprise a crown wheel (25), wherein the crown wheels (25) are connected to each other via a shaft (27), said shaft (27) having a pinion (28) at its respective ends, which engages into a respective crown wheel (25). Such a drive train allows retrofitting the drive train with simple constructional means, in particular standardized means, from an initial state with only one driven axle to all-wheel drive. |
