Abstract
Abstract Clutch disk assembly, includes a hub member, a flange carried by the hub member, respective disks mounted on the hub member at opposite sides of the flange, force storage means engageable with the flange and the disks so as to afford rotational play of the disks relative to the flange in a direction opposite the biasing action direction of the force storage means, and at least one friction device disposed between and effective upon the relatively rotatable flange and disks, the flange being dish-shaped and having a substantially conical portion in a radial region thereof disposed between the outer periphery thereof and the location of the friction device.
