Abstract
A drive train (2) of a purely electrically drivable motor vehicle has at least one electric machine (13, 14), a transmission (21), a planetary differential (22) and a drivable axle (2). The axle (2) can be driven by the electric machine (13, 14) via the transmission (21) and the differential (22). The planetary differential (22) has an input (32, 33) connected to the electric machine (13, 14), a first output (28, 34, 35, 36, 37, 38) connected to a first section (4) of the drivable axle (2), and a second output (30, 31, 42) connected to a second section (5) of the drivable axle (2). Rotational axes of the input and outputs of the planetary differential (22) form an intermediate axis (53) arranged between an axle (15) of a rotor (17) of the electric machine (13, 14) and the drivable axle (2).
