Lubrication and cooling system for power receiving and delivery units in an electro-mechanical vehicular transmission

A lubricating and cooling assembly particularly adapted for use with power receiving and delivery units that are encased in the housing of a vehicular transmission, said assembly comprising:

• a source of pressurized lubricating and cooling fluid;
• a web plate extending transversely of the transmission housing;
• said web plate having an outer rim adapted to engage the transmission housing;
• a discharge chamber provided in association with said web plate and located in proximity to said outer rim;
• said discharge chamber defined by a unified annulus located radially inwardly with respect to the outer rim of said web plate and extending axially from said web plate;
• fluid communication means penetrating said web plate to transfer pressurized fluid from said source of pressurized lubricating and cooling fluid to said discharge chamber;
• a plurality of bores circumferentially spaced along a reference circle on the axial extent to which said unified annulus extends axially of said web plate;
• each said bore terminating in a transverse retaining shoulder;
• each said bore adapted to receive a spray ring plug;
• each said spray ring plug has a cylindrical outer wall that circumscribes said discharge chamber;
• one end of said discharge chamber terminates in a transverse base plate that is penetrated by one of said orifices;
• when said spray ring plug is operatively received within said bore, that axial end of said spray ring plug at which said transverse base plate is located engages said retaining shoulder;
• a closure plate, also penetrated by one of said orifices, defines the end of said discharge chamber opposite said transverse base plate;
• means are provided selectively to secure said spray ring plug within said bore and in engagement with said retaining shoulder;
• one or more orifices penetrating a wall of said discharge chamber to dispense a spray of the lubricating and cooling fluid onto one or more of said power receiving and delivery units located in proximity to said spray ring plug;
• an accumulation chamber is recessed within the exterior of said outer wall;
• and
• said accumulation chamber communicates with said discharge chamber through port means that penetrate said outer wall.
