1. A drive unit for a drive train of an electrically drivable motor vehicle, the drive unit comprising:
a first electric machine including a rotor;
a second electric machine including a rotor;
a first shaft to which the rotor of the first electric machine is rotationally fixed;
an output shaft to which the rotor of the second electric machine is rotationally fixed;
a separating clutch, with which the rotor of the first electric machine is connectable to the output shaft for torque transmission;
a connection element configured for rotationally fixed connecting of an internal combustion engine;
a first gear ratio step is arranged with a gear ratio i<1 between the connection element and the shafts, which are rotationally fixed to the rotors of the electric machines; and
an electro-mechanical parking lock unit configured such that a rotary movement of an output of the first gear ratio step is blockable therewith, wherein the output shaft has a locking toothing for positive engagement of a locking element of the electro-mechanical parking lock unit.
