APPARATUS FOR A DRIVE SYSTEM HAVING A CARTRIDGE HOUSING ONE OR MORE ELASTOMER MEMBERS

摘要

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.

1. An apparatus for a drive system comprising:
a hub having a sleeve defining a bore for receiving a shaft, thereby defining an axis of rotation, and an outer annular ring spaced radially outward from the sleeve, thereby defining an annular receptacle therebetween; a component for rotation with the hub, the component having an inner annular ring disposed between the sleeve and the outer annular ring of the hub; an annular cartridge defining a first annular groove that has a generally C-shaped or U-shaped cross-sectional profile, the annular cartridge seated between the inner annular ring of the component for rotation with the hub and the sleeve or the outer annular ring of the hub with the first annular groove open radially outward; and a first elastomer member seated in the first annular groove in compression, thereby operatively coupling the component for rotation with the hub to the hub for rotation therewith.
