  • Housing configuration for an electric machine with cooling jacket
    Patent number: 10476352
    Abstract: A housing configuration for an electric machine includes a housing having a stator receiving region with a wall. A stator is disposed in the stator receiving region of the housing and a sleeve is pushed onto the stator. A cooling jacket surrounds the stator for liquid cooling of the stator. The cooling jacket has a radially outer cooling-jacket surface and a radially inner cooling-jacket surface with a gap between the radially outer cooling-jacket surface and the radially inner cooling-jacket surface. The wall of the stator receiving region forms the radially outer cooling-jacket surface of the cooling jacket. The sleeve forms the radially inner cooling-jacket surface of the cooling jacket. Bilaterally acting seal carriers are inserted into the gap between the radially outer cooling-jacket surface and the radially inner cooling-jacket surface. The bilaterally acting seal carriers provide an axial sealing of the cooling jacket. An electric machine is also provided.
