  • Differential assembly with features for improved lubrication
    Patent number: 8684876
    Abstract: A power transmitting component includes a housing having an interior cavity with a sump, a lubricant disposed in the sump, and a component mounted in the housing assembly for rotation about a first axis. The component rotates through the lubricant in the sump to generate a stream of lubricant that is slung from the component as it rotates at a speed in excess of a predetermined speed. The housing includes a deflector that extends into the interior cavity and has a first face having an impingement portion and a first edge adjacent the impingement portion. The impingement portion extends into the stream and deflects a portion of the stream towards the first edge. The first edge disperses the portion of the stream toward selected areas in the interior cavity.
