Abstract

A drive device (2) for an at least partially electrically driven vehicle (1) includes an electric machine (3) having a rotor shaft (8) extending longitudinally along an input axis (4). The drive device further includes a first output shaft (6a) extending longitudinally along an output axis (7) and parallel to the rotor shaft (8). Moreover, the drive device includes a gear stage (5) having a first gearwheel (9) rotationally fixed to the rotor shaft (8), and a second gearwheel (10) meshed with the first gearwheel (9) and drivingly connected to the first output shaft (6a). Additionally, the drive device includes a housing (11) having a shared housing cavity (12), wherein the first output shaft (6a) and the electric machine (3) are parallel to one another in the housing cavity (12), and wherein an air gap (18) extends radially between the electric machine (3) and the first output shaft (6a).
