Problems solved by technology
Additionally, as the clutch rotates, centrifugal force can cause fluid to move toward the outside of the clutch, causing uneven distribution of fluid across the clutch plates
As a result, maintaining the optimal amount and location of fluid within the clutch during engagement and disengagement can be difficult

Embodiment Construction
[0015] Example embodiments will now be described more fully with reference to the accompanying drawings.
[0016] Refer to the attached figure 1 , an example of a vehicle having a clutch arrangement constructed in accordance with the teachings of the present disclosure is indicated generally at 10 . Vehicle 10 may have a powertrain 12 and a driveline or driveline 14 . The powertrain 12 may be conventionally constructed and may include a power source 16 and a transmission 18 . Power source 16 may be configured to provide propulsion power and may include an internal combustion engine and / or an electric motor, for example. The transmission 18 can receive propulsion power from the power source 16 and can output power to the driveline 14 . Transmission 18 may have multiple automatically or manually selected gear ratios.
[0017] The driveline 14 in the particular example provided is an all-wheel drive (“AWD”) configuration, but those skilled in the art will appreciate that the ...

The present disclosure relates to a multi-plate friction clutch with central lubricant supply and lubricant drain capabilities. The clutch device of the present disclosure may include a differential and first and second conduits. The differential may transmit differential power to the first output and the second output. A clutch plate is rotatable through the clutch chamber and transmits power between the second and third outputs. An outer carrier and an inner carrier may be coupled for rotation with the second output and the third output, respectively. The first conduit may open to a first perimeter region of the clutch chamber and fluidly couple the first region to a chamber separate from the clutch chamber. The second conduit may open into a second perimeter region circumferentially spaced from the first region. The second conduit may fluidly couple the second region to a central region of the clutch cavity. Rotation of the outer carrier in opposite rotational directions throws lubricant to the first and second conduits, respectively.
Description
technical field [0001] The present disclosure relates to a clutch device including a multi-plate friction clutch with central lubricant supply capability and lubricant discharge capability. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] A power transfer component having a torque transfer device, such as a disconnect transmission module in an all wheel drive ("AWD") system, typically includes a clutch having a plurality of friction plates and pistons for selectively engaging the plates. The pads are typically immersed in fluid to provide lubrication and cooling to the pads when the clutch is engaged. These plates usually separate when the clutch is disengaged. When disengaged, excess fluid in the clutch sump between the plates and through which the plates rotate increases system drag torque. It would be beneficial to reduce the amount of system drag torque. Minimizin...
