Abstract

A drive train (1) of an all-electrically drivable motor vehicle has a first axle (2) with a differential (6), and two electric machines (15, 16). The first axle (2) can be driven by the electric machines (15, 16) via a transmission (17). One (16) of the two electric machines (15, 16) can be decoupled from the transmission (17) via a switchable clutch (23). Different driving conditions of the motor vehicle operated by the drive train can be executed with a particularly good efficiency.
