12. A hybrid transmission device (1) for a motor vehicle (100), comprising:
a first transmission input shaft (2) for connecting an internal combustion engine (3);
a second transmission input shaft (4) for connecting a rotor of a first electric machine (5);
a superposition gear unit (6) arranged axially parallel to the first transmission input shaft (2) and to the second transmission input shaft (4), the superposition gear unit (6) configured for connecting the first electric machine (5), the superposition gear unit (6) comprising a first planetary gear set (P1) with a sun gear (P11), a ring gear (P12), and a planet carrier (P13) with planet gears (P14) rotatably arranged thereon;
a gear reduction stage (7) comprising a first spur gear pair (ST1) and a second spur gear pair (ST2) for connecting the superposition gear unit (6) to a differential (8), wherein the differential (8) comprises a first axle shaft (9a) and a second axle shaft (9b), each of the first and second axle shafts (9a, 9b) configured for connecting a wheel of the motor vehicle, wherein the second axle shaft (9b) extends axially at least through the superposition gear unit (6); and
a plurality of shift elements comprising a first shift element (A), a second shift element (B), and a third shift element (C) configured for implementing an electrodynamic driving-off process and a purely electric or hybridized drive of the motor vehicle, the third shift element (C) being configured for interlocking the first planetary gear set (P1) of the superposition gear unit (6).
