  • Patent number: 11660949
    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).

  • Publication number: 20230147217
    Abstract: An electric motor may have a housing (which may be round), and a rotor that rotates on a rotor shaft, located within that housing. Hinged levers between the housing and the stator may be pivotable radially on the housing. Forces from the stator in the circumferential direction may be transferred rigidly to the housing by the hinged levers. The hinged levers may allow for radial movements and deformations of the stator upon receipt of these forces.

  • Patent number: 11578794
    Abstract: A device (1) for cooling and lubricating components of a vehicle (2) may include a housing (3), a coolant sump (4), a coolant pump (5) for pumping coolant (6) from the coolant sump (4), a heat exchanger (7) for cooling coolant (6) from the coolant pump (5), and a coolant line system (8) including a coolant reservoir (9) having a single coolant inlet (10) and multiple coolant outlets (11.1, 11.2, 11.3, 11.4, 11.5). The coolant line system (8) fluidically connects the coolant pump (5) to the heat exchanger (7), and the heat exchanger (7) to the single coolant inlet (10) of the coolant reservoir (9). The coolant reservoir (9) receives coolant (6) from the heat exchanger (7) via the single coolant inlet (10) and directs coolant (6) via the multiple coolant outlets (11.1, 11.2, 11.3, 11.4, 11.5) onto components in the housing (3) requiring cooling and lubrication.
