Abstract
A clutch assembly comprises an input shaft and an output shaft, co-axially arranged relative to the input shaft. The clutch assembly further comprises an input clutch drum, fixed to the input shaft, and an output clutch drum, translatable relative to the output shaft. The clutch assembly further comprises a clutch pack and a clutch piston that is translatable relative to the output shaft between, inclusively, a frictionally disengaged clutch-pack position and a frictionally engaged clutch-pack position. The clutch assembly additionally comprises a clutch-pack engagement spring. The output clutch drum is translatable between, inclusively, a fully disengaged position and, inclusively, a positively engaged position. When the clutch piston is in the frictionally disengaged clutch-pack position, the internal splines of the output clutch drum are not in mesh with the external splines of the input clutch drum.
