  • Lubrication and cooling system for power receiving and delivery units in an electro-mechanical vehicular transmission
    Patent number: 6579202
    Abstract: Lubrication and cooling assemblies particularly adapted for use with power receiving and delivery units that concentrically circumscribe planetary gear subsets encased in the housing of a vehicular transmission. Such assemblies utilize a source of pressurized lubricating and cooling fluid and employ a web plate extending transversely of the transmission housing. The web plate has an outer rim located in proximity to the transmission housing. A discharge chamber is provided in association with the web plate and is located in proximity to the outer rim. Fluid communication means penetrate the web plate to transfer pressurized fluid from the source of pressurized lubricating and cooling fluid to the discharge chamber. One or more spray rings define at least one wall of the discharge chamber, and one or more orifices penetrating the spray ring.
