Torsional vibration damper with an interlocked isolator

A crankshaft damper-isolator comprising:

• a hub having an outer radial surface and an outermost radial surface spaced radially outward from the outer radial surface and thereby defining an annular receptacle therebetween;
• a pulley body having a belt engaging portion radially-concentric about the hub and, extending radially inward from the belt engaging portion, a face guard that terminates in a sleeve seated about the outer radial surface of the hub;
• a damper assembly disposed between the outermost radial surface of the hub and belt engaging portion of the pulley body;
• an isolator member seated in the annular receptacle of the hub, wherein the isolator member is engaged with both the hub and the face guard for rotation therewith when the hub and pulley body rotate at the same rotational speed and when the hub rotates relative to the pulley body;
• and
• a slide bearing disposed between the outer radial surface of the hub and the sleeve of the pulley body, wherein the slide bearing axially retains the pulley body to the hub and allows the pulley body to rotate relative to the hub.
