ABSTRACT:
The invention provides a structural member for a vehicle transmission formed with an annular recess in fluid communication with a fluid source and at least partially enclosing and defining an interior space of the transmission. An interior component, such as a motor/generator, is located in the interior space. The annular recess directs cooling fluid provided from the fluid source onto the interior component. The end cover includes structure defining a flow passage in fluid communication with a fluid source and also defining an annular recess in fluid communication with the flow passage. The flow passage and the annular recess are cooperatively configured for directing fluid provided from the fluid source onto an interior component in the interior space for cooling the interior component. Preferably, the interior component is an electric motor/generator that includes a stator having electric windings. The fluid is directed from the annulus onto the electric windings.
