Claims16
A casing for a drive unit of a motor vehicle, the casing comprising:
- an interior space within which at least one of an electric motor or a transmission is configured to be arranged in the casing;
- a projection disposed above the interior space, the projection defining a calming chamber inside the projection;
- and
- a shaft extending from the projection, the shaft arranged in an inclined position running obliquely relative to horizontal, horizontal being defined perpendicular to gravity, the shaft comprising:
- a first end adjoining the calming chamber, the first end being a lowest end of the shaft;
- a second end opposed to the first end, the second end being a highest end of the shaft, the second end defining a stepped portion;
- and
- a through-hole from the first end to the second end by which the shaft is configured to vent the calming chamber, the through-hole comprising a diameter smaller than the stepped portion, the stepped portion being concentric with the through-hole;
- wherein the stepped portion accommodates a permeable membrane.
