Abstract
A drive assembly for a motor vehicle drive train is provided. The drive assembly includes a clutch pack, a hub, a main piston axially movable with respect to the hub to engage the clutch pack and a clutch control assembly nonrotatably fixed to the hub. The clutch control assembly forms a pressure chamber with the main piston. Rotation of the hub causes the clutch control assembly to close an engagement gap of the clutch pack. Pressure in the pressure chamber moves the main piston to engage the clutch pack after the engagement gap is closed.
