Abstract
A differential assembly includes a housing defining a space containing a volume of hydraulic fluid, the housing including interior surfaces. A gear that rotates in the housing includes surfaces that pass through the fluid as the gear rotates and on which the fluid is carried to the interior surfaces of the housing. A bearing located in the housing is supplied with fluid from a fluid path that hydraulically connects the interior surfaces and the bearing.

A differential assembly comprising:
- a bearing;
- a housing defining a space containing a volume of hydraulic fluid, the housing including an interior surface, a passage directed toward the bearing and including a inner end from which fluid is directed toward the bearing, and an outer end;
- a gear that rotates in the housing including gear surfaces that pass through the fluid as the gear rotates and on which the fluid is carried to the interior surface of the housing;
- a channel formed in the housing and communicating with the radial outer end of the passage;
- and
- a first rib secured to the inner surface of the housing, including a surface that extends and is inclined away from said interior surface, said surface of the first rib extending laterally toward the bearing and inclined toward the channel.
