Drive device for a motor vehicle, in particular for a car

A drive device for a motor vehicle, the drive device comprising:

• an electric engine, which is an axial flow engine comprising a stator and two rotors rotatable in relation to the stator, wherein the stator is arranged between the two rotors in the axial direction of the axial flow engine;
• and
• a differential transmission arranged at least partially radially inside the stator and comprising a first driven gear non-rotationally connected to a first driven shaft and a second driven gear non-rotationally connected to a second driven shaft,
• wherein the two rotors each have a rotor support, wherein the rotor supports of the two rotors are connected to one another in a form-fit manner and form a differential housing when seen at least in an axial direction of the electric engine, wherein
• the differential transmission is a planetary differential,
• the first driven gear is a first sun gear non-rotationally connected to the first driven shaft,
• the second driven gear is a second sun gear non-rotationally connected to the second driven shaft,
• the planetary differential has at least two planetary bolts respectively held on the two rotor supports, and via the planetary bolts the two rotor supports are connected to one another in a form-fit manner,
• the planetary differential has at least one first planetary gear held on a first of the at least two planetary bolts and meshing with the first sun gear, and
• the planetary differential has at least one second planetary gear rotatably held on a second one of the at least two planetary bolts and meshing with the second sun gear,
• the second planetary gear meshes with the first planetary gear.
