Patent attributes
A vehicle stalactite passive lubrication system includes a drive unit having an electric motor and a gear. A sump has a sump extension. A lubricant is collected in the sump for gravity flow into the sump extension. A stalactite member is fixed to the drive unit and is positioned above an element to be filled with a fluid, lubricated or cooled. The stalactite member is directed downwardly toward the sump with the lubricant splashed by gear rotation collected on neighboring walls and the stalactite member and directed downwardly by gravity into the sump or target element. The stalactite member includes: a drip edge oriented at an angle to a horizontal plane; and a tip defining an end of the drip edge. The angle is selected to direct the lubricant to discharge off the stalactite member at the tip as a lubricant stream into the sump or target element.
