Abstract
A wedge clutch imparts a wedging effect to selectively transfer power through powertrain components. The wedge clutch includes a hub configured to rotate about an axis and having a tapered hub surface. A rotatable member is configured to rotate about the axis. A plurality of wedge segments are arranged annularly about the axis and are disposed radially between the hub and the rotatable member. The wedge segments can collectively radially expand and contract to lock and unlock the clutch. Each wedge segment defines an aperture therethrough. A cage assembly includes a plurality of pins that each extend through a respective one of the apertures to control relative radial movement of the wedge segments.
