Abstract
A clutched device can include a differential and first and second conduits. The differential can transmit differential power to first and second outputs. Clutch plates can rotate through a clutch cavity and transmit power between the second output and a third output. An outer carrier and an inner carrier can be coupled for rotation with the second and third outputs, respectively. The first conduit can be open to a first peripheral region of the clutch cavity and fluidly couples the first region to a cavity separate from the clutch cavity. The second conduit can be open to a second peripheral region that is circumferentially spaced apart from the first region. The second conduit can fluidly couple the second region to a central region of the clutch cavity. Rotation of the outer carrier in opposite rotational directions slings lubricant to the first and second conduits, respectively.
