Abstract
Torsional vibration dampers for FEADs are disclosed that include a hub having a sleeve defining a bore for receiving a shaft and an outer annular ring spaced radially outward from the sleeve, thereby defining an annular receptacle, a component for rotation with the hub having an inner annular ring disposed between the sleeve and the outer annular ring of the hub, and an annular cartridge seated in the annular receptacle between the inner annular ring of the component for rotation with the hub and the sleeve or outer annular ring of the hub. The annular cartridge defines a first annular groove having a generally C-shaped or U-shaped cross-sectional profile open radially outward, and has a first elastomer member seated therein in compression, thereby operatively coupling the component for rotation with the hub to the hub. The component may be a pulley body or an inertia member.
