Abstract
A drive assembly for a motor vehicle drivetrain includes a differential configured for driving a first output shaft and a second output shaft about a center axis and for allowing the first output shaft and the second output shaft to rotate about the center axis at different speeds, and planet gears each rotatably mounted on a respective planet carrier. The planet gears each include a radially extending surface and blades circumferentially spaced part from each other. The blades axially protrude from the radially extending surface for directing a fluid flow axially toward the differential during operation of the drive assembly.
