Abstract
A decoupler assembly for transferring torque between a shaft and an endless power transmitting element. The decoupler assembly includes a clutch spring that is formed only of wire for transmitting rotary power between a carrier and a pulley. The decoupler assembly further includes a hub, that is configured to be coupled to a driven shaft, and a torsion spring that transmits rotary power between the carrier and the hub. A lubricant is disposed on the coils of the clutch spring. The pulley and the hub cooperate to define an annular cavity in which the torsion spring and the clutch spring are disposed. The torsion spring and the clutch spring are disposed axially between the carrier and the hub.
