Abstract
A vehicle final drive unit (FDU) of a vehicle driveline. The vehicle FDU includes one or more wet clutches that provide disconnect capabilities in the vehicle FDU, and includes a final drive gearset. Different techniques are provided for discontinuing lubricant supply to the wet clutch(es) when the wet clutch(es) are disconnected in order to preclude unwanted rotations that can be the consequence of adhesion among clutch plates in the wet clutch(es). One technique actively brakes the final drive gearset in the vehicle FDU so that the final drive gearset no longer rotates and no longer throws lubricant to the wet clutch(es). Another technique involves closing an entrance that leads lubricant to the wet clutch(es).
