Abstract
A clutch assembly for a torque converter including: a plurality of annular friction elements; a pressure plate; and a restraining plate engageable with a portion of the plurality of annular friction elements and arranged to limit axial movement of a portion of the annular friction elements to a maximum distance from the pressure plate. In some aspects, the restraining plate is rotationally connected to the pressure plate. In some aspects, the pressure plate includes an axial protrusion arranged to limit the axial movement of the plurality of annular friction elements away from the pressure plate. In some aspects, the clutch assembly includes a plate radially overlapping the restraining plate to limit the axial movement of the plurality of annular friction elements away from the pressure plate.
