Abstract
A drivetrain component is provided that may include a housing, a component, a cover and a pair of bearings. The housing may define an internal cavity and a pair of bearing bulkheads. The component may be received in the internal cavity. The cover may be coupled to the housing and may close a side of the internal cavity. The cover may include a pair of bearing caps. Each of the bearing caps may be mounted to a corresponding one of the bearing bulkheads. The pair of bearings may be received on the component. Each bearing may be engaged to an associated one of the bearing bulkheads and an associated one of the bearing caps.

12. A drivetrain component comprising:
-
a carrier housing having a pair of bearing bulkheads and a pair of mounting flanges, the bearing bulkheads defining a rotational axis, the mounting flanges being disposed on opposite sides of the rotational axis such that a first one of the mounting flanges spans the bearing bulkheads on a first side of the rotational axis and a second one of the mounting flanges spans the bearing bulkheads on a second side of the rotational axis; a differential assembly mounted to the bearing bulkheads, the differential assembly comprising a differential case and a pair of differential bearings mounted to the differential case, the differential bearings being received on the bearing bulkheads; and a cover having a shell portion and a bridge portion, the shell portion being mounted to the mounting flanges, the bridge portion being coupled to the bearing bulkheads and securing the differential bearings to the carrier housing. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
