Abstract
A hybrid transmission device () includes a first transmission input shaft (), a second transmission input shaft (), a superposition gear unit () arranged axially parallel to the first transmission input shaft () and to the second transmission input shaft () and configured for connecting an electric machine (). The superposition gear unit () includes a first planetary gear set (P) with a sun gear (P), a ring gear (P), and a planet carrier (P) with planet gears (P) rotatably arranged thereon. A gear reduction stage () includes a first spur gear pair (ST) and a second spur gear pair (ST) for connecting the superposition gear unit () to a differential (). At least a first shift element (A), a second shift element (B), and a third shift element (C) are configured for implementing an electrodynamic driving-off process and a purely electric or hybridized drive of the motor vehicle.
