  • Patent number: 11831217
    Abstract: A cooling crescent for a hybrid module includes a first half section and a second half section. The first half section has a radially outer inlet orifice and a plurality of circumferentially disposed radially inner outlet orifices. The second half section is sealed to the first half section to form a narrow channel hydraulically connected to the radially outer inlet orifice, and a circumferentially extending channel hydraulically connected to the narrow channel and the plurality of circumferentially disposed radially inner outlet orifices. In some example embodiments, the first half section or the second half section comprises a plurality of axially extending tabs with respective orifices for fixing the cooling crescent to a housing of the hybrid module. In an embodiment, the plurality of axially extending tabs are configured to be adjustable to vary a respective height of the tabs to accommodate for e-motor stators of varying sizes.

  • Publication number: 20230231440
    Abstract: A shipping jig for an e-motor includes a central axis, an annular disk arranged for fixing to a cover of the e-motor, and a cylindrical portion extending axially from the annular disk and arranged for axially and radially positioning a rotor carrier of the e-motor relative to a stator of the e-motor. The annular disk includes a first plurality of holes distributed about a first bolt circle and a second plurality of holes distributed about a second bolt circle, smaller than the first bolt circle. The cylindrical portion may also be arranged for radially positioning a portion of a resolver relative to the stator. The first plurality of holes may each have a same third diameter and the second plurality of holes may each have a same fourth diameter, greater than the same third diameter.
