  • Patent number: 12612946
    Abstract: An assembly, which may be a gear box, differential or eAxle assembly, having a housing with a bearing seat and a snap ring groove, and a rolling bearing located on the bearing seat adjacent to the snap ring groove. A snap ring is located in the snap ring groove, with the snap ring extending radially along a portion of the rolling bearing. A press-fit retainer is engaged to the housing with a press-fit on an axially opposite side of the snap ring from the rolling bearing to support the snap ring. An assembly method is also provided.

  • Publication number: 20260016047
    Abstract: A bearing arrangement utilizing a typical lip seal pressed into a bore to act as a reacting spring surface which keeps a bearing outer race preloaded to prevent unintentional bad bearing operation (e.g., outer race spinning or ball sliding). This spring reacting surface serves to discourage, for example, outer race spinning or ball sliding, packaged in a tight, space efficient location to permit critical space to be used for other functions. Aspects include retention feature for retaining a biasing element in the bore prior to assembly.

  • Patent number: 12500475
    Abstract: An electric drive unit includes a housing, a motor, a sleeve, first and second seals, and a bearing. The housing defines gearbox and motor housing regions, and first and second channels extending between the gearbox and motor housing regions. The motor is disposed within the motor housing region and has a rotor and a rotor shaft that is rotationally driven about an axis. The sleeve extends circumferentially along an exterior surface of the rotor shaft and has an inner surface that interfaces with the exterior surface, and an outer surface opposite the inner surface. The first seal extends between the outer surface of the sleeve and the housing. The second seal extends between the inner surface of the sleeve and the exterior surface of the rotor shaft. The bearing is positioned radially between the rotor shaft and the housing and axially between the first seal and the gearbox region.

  • Patent number: 12431758
    Abstract: An electric drive unit includes an electric motor having a rotor shaft that defines a hollow that is accessible via an opening defined at an axial end of the rotor shaft. The hollow defines a portion of a fluid flow path. The electric drive unit also includes an output shaft that extends into the hollow through the opening. The electric drive unit further includes a baffle that extends into the hollow through the opening. The baffle is arranged to redirect fluid flowing along the fluid flow path away from a portion of at least one of the rotor shaft and the output shaft.
