Abstract
A friction clutch for a motor vehicle includes a cover, a pressure plate, a biasing member and an adjustment mechanism. The adjustment mechanism includes a first annular cam, a second annular cam and a torsional spring and housing assembly. The cover has an axis of rotation. The pressure plate is coupled to the cover for rotation therewith about the axis. The pressure plate has a frictional engagement surface substantially normal to the axis. The pressure plate has a plurality of cooling blades extending from the pressure plate on a side opposite the frictional engagement surface. The blades are located at a first radial distance from the axis. The biasing member is interposed between the cover and the pressure plate, and biases the pressure plate toward an engaged pressure plate position. The adjustment mechanism is centered about the axis and is located at a first radial distance from the axis. The adjustment mechanism is operably disposed between the biasing member and the pressure plate. The first annular cam is rotatably fixed with respect to the pressure plate. The second annular cam is rotatable relative to the first annular cam. Both cams have a plurality of mutually engage…
