Abstract: A transmission includes a clutch configured to selectively couple a clutch hub to a clutch housing. The clutch hub includes a channel to provide oil from a central passageway to remove heat from a clutch pack. The oil runs along a disk of the clutch hub to a perforated annular ring of the clutch hub, then through the perforations to the clutch pack. An oil deflector limits the flow of oil at low clutch hub speeds. The deflector is mounted to the clutch hub disk to create a flow restriction. At low speeds, the oil builds up in a reservoir radially inside the restriction and then spills over a dam and is directed away from the clutch pack by a conical surface. The reduced oil flow at low speeds reduces parasitic loss. At higher speeds, centrifugal forces increase the flow rate.
