Abstract
A torque converter including an axis of rotation and a flange rotatable about the axis of rotation is disclosed. The torque converter includes a turbine shell independently rotatable about the axis of rotation relative to the flange. A first plate, disposed between the flange and the turbine shell, may be fixed to the turbine shell. A second plate, disposed between the flange and the turbine shell, may be radially outward relative to the first plate. The torque converter further includes a cover having an inner surface and a third plate disposed between the flange and the cover. The first plate may include at least one ramp protruding in an axial direction toward the flange, wherein the ramp is rotatably engageable with the flange for urging the flange axially in a direction toward the cover, and for transmitting an axial force for urging a clutch to engage.
