A method and device for liquid cooling of an electric motor and a transmission configuration. The electric motor includes a rotor with a rotor shaft and a stator provided with windings, and the transmission configuration includes a transmission shaft. The rotor and transmission configuration are journally supported by a support configuration. Supplying a liquid for cooling via the support configuration is performed in such a way that the electric motor as well as the transmission configuration are cooled.

Method and device for liquid cooling of electric motor and transmission configuration

The present invention relates to an electric drive device for driving of a motor vehicle comprising an electric motor arranged to be media supplied, the electric motor having a jacket surface and an essentially ring shaped cross section, wherein said media supply is arranged to be effected via a connection unit arranged in connection to the jacket surface of the electric motor. The invention also relates to a motor vehicle with an electric drive device.

Electric drive device for motor vehicle with oil sump formed therein for cooling and lubrication

The present invention relates to an electric drive device comprising an electric motor () with a stator and a rotor arranged to rotate a drive shaft, wherein said electric motor () is arranged to be accommodated in a housing, further comprising opposite gear housings surrounding the electric motor, each containing a transmission configuration, wherein the electric drive device comprises a housing configuration in which the electric motor () as well said opposite gear housings () are accommodated, wherein each gear housing () is attached and hereby locked to said housing configuration. The invention also relates to a motor vehicle.

Electric drive device

The invention relates to an electric drive device () comprising an electric motor () with a stator () and a rotor () arranged to rotate a drive shaft (), a housing () in which the electric motor () is housed, which housing has an essentially ring shaped cross section with an imaginary center axle (X), wherein the electric motor () is eccentrically arranged in the housing () in such a way that the rotational center of the drive shaft () of the electric motor () runs essentially parallel to and at a distance from the center axle of the housing () so as to form a desired space () between the electric motor and said housing. The invention also relates to motor vehicle with an electric drive device.
