Abstract: An automotive air conditioning compressor clutch eliminates all rivets and utilizes only one return spring. A hub with multiple radial teeth closely fitting into armature openings supports the armature plate concentric and parallel to a pulley friction disk. The armature is free to slide relative to the hub as the return spring is compressed. The thrust areas between the hub teeth and armature are large, which reduces compressive stress. The lower stress reduces the wear rate for both the all-metal and rubber torque cushion versions of the clutch.
