Abstract
A torque transmitting device () includes a clutch housing () rotatable about an axis (A), a first set of clutch plates (A) splined to the clutch housing (), and a second set of clutch plates (B) interleaved with the first set and rotatable about the axis (A) of rotation. A push plate assembly () is splined to the clutch housing () for rotation therewith. A roller assembly () includes a roller housing () splined to the clutch housing (), a roller supporter () housed in the roller housing (), and a roller element () supported by the roller supporter (). A wedge assembly () includes a wedge housing () connected to a wedge block (). The wedge housing () includes a ramp member () defining a ramp surface () with the roller element () contacting the ramp surface (). A motion converter () is disposed between the push plate assembly () and the wedge housing () such that axial movement of the push plate assembly () causes rotation of the wedge assembly () relative to the roller assembly ().
