ABSTRACT:
A coupling arrangement is disclosed for establishing a rotary connection between an axially movable armature element and a rotary drive hub, which transmits torque from the hub into the armature while allowing limited axial movement of the armature against an axial spring force exerted by the coupling arrangement. The coupling arrangement includes a series of circumferentially extending leaf springs, each having one end pinned to the armature and the other riveted to the hub. The circumferential pattern of the spring links is such that each link overlies other spring links in the series to enable the length of the spring link to be great enough to insure adequate flexibility of the links to accommodate axial movement of the armature, while enabling a sufficient number of the spring links to be disposed about the armature and hub axis to adequately transmit the torque through the clutch unit.
