Abstract
One implementation of a vehicle power transfer unit (PTU) housing, such as that for an automobile, has an oil feed passage extending through one of its walls and at its interior. The oil feed passage delivers oil to gears, bearings, and/or other components equipped inside of the PTU housing and suspended above an oil bath in the PTU housing. Oil of the oil bath is thrown about by rotating gears and makes its way through the oil feed passage and to the gears, bearings, and/or other components. With the oil feed passage, the PTU housing does not rely solely on oil sloshing and splashing and being slung around inside of the PTU housing as the technique for getting oil to the gears, bearings, and/or other components.
