Abstract
A clutch includes a hub and a carrier supported for rotation about a common axis. The carrier has a fixed portion and a sliding member that cooperate to define a groove. Movement of the sliding member changes a width of the groove. The clutch further includes a disk having a first edge disposed on the hub and a second edge disposed in the groove. The disk frictionally engages between the hub and the carrier when the clutch is locked. The sliding member is biased such that the groove has a first width for a first range of torques between the disk and the groove and a second width that is greater than the first width for a second range of torques between the disk and the groove that is greater than the first range of torques.
