Abstract: A driveline unit housing includes a body defining an interior, a central portion, and a plurality of openings each adapted to receive a shaft. A mounting body has a mounting surface defining one of the openings, the mounting surface includes a plurality of mounting holes and has a peripheral length greater than that of the central portion. Support walls extend between the central portion and mounting body, and extend axially relative to an axis of rotation of a shaft received through the opening defined by the mounting surface, and at least a majority of the support walls extend radially and a plane through and parallel to each such support wall intersects an axis of the mounting holes and the axis of rotation. Spaces defined between the support walls span a majority of a circumference of an imaginary circle that intersects each support wall.

Abstract: A housing of a vehicle differential, such as an automotive driveline differential, supports one or more gearsets in assembly. A wall of the housing has one or more windows that provide access to the gearset(s). One or more protuberances are situated at an exterior surface of the wall and near the window(s). The protuberance(s) provide a thickened portion in the wall to strengthen and reinforce the wall against stresses experienced during use of the vehicle differential.
