Embodiment Construction

[0021] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0022] with reference to the attached figure 1, an example of a vehicle having a clutch device constructed in accordance with the teachings of the present disclosure is indicated generally by the reference numeral 10 . Vehicle 10 may have a powertrain 12 and a driveline or driveline 14 . The powertrain 12 may be constructed in a conventional manner and may include a power source 16 and a transmission 18 . Power source 16 may be configured to provide propulsion power and may include, for example, an internal combustion engine and / or an electric motor. The transmission 18 can receive propulsion power from the power source 16 and can output power to the driveline 14 . The transmission 18 may have multiple automatically or manually selected gear ratios. In the particular example provided, driveline 14 is an all-wheel drive (“AWD”) configuration, but those skilled in the a...

Abstract

A clutched device has a housing, which defines a clutch sump, a friction clutch that is received in the housing, a first reservoir, an evacuation device and a pump that is configured to transmit fluid between the first reservoir and the friction clutch for operating the friction clutch. The evacuation device is selectively operable for changing the effective volume of the clutch sump so that the level of lubrication in the clutch sump can be lowered to reduce drag forces caused by the presence of lubricant between clutch plates of the friction clutch when the friction clutch is not in use.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 114657, filed February 11, 2015, the disclosure of which is hereby incorporated by reference as if fully set forth in detail. technical field [0003] The present disclosure relates to a clutch device including a clutch pack with a fluid evacuation system. Background technique [0004] This section provides background information related to the present disclosure which is not necessarily prior art. [0005] A power transfer component having a torque transfer device, such as a split drive module in an all wheel drive ("AWD") system, typically includes a clutch having a plurality of friction plates and a piston for selectively engaging the friction plates. The friction plates are typically immersed in fluid to provide lubrication and cooling to the plates when the clutch is engaged. When the clutch is disengaged, the plates usually separate...
