Abstract
An assembly includes an output shaft, an input shaft with an internal reservoir, and a clutch. The clutch is adapted to selectively engage and couple the input shaft to the output shaft. The clutch has a pressure chamber that communicates with the reservoir of the input shaft. The reservoir has a sufficient volume to provide the pressure chamber with a fluid pressure adequate to maintain engagement of the clutch during an interruption of a fluid supply to the input shaft and clutch.
