Abstract
A decoupler with driven and driving members, a clutch, a torsional vibration damper and a lubricant. The clutch is received in a bore in the driven member and includes a carrier, a wrap spring and at least one spring. The wrap spring is formed of spring wire and has a plurality of coils disposed between a first end, which is received in a groove in the carrier, and a second end. The portion of the wrap spring outside the carrier has an outer circumferential spring surface that is abutted against the inner circumferential surface of the bore. The at least one spring is disposed between the carrier and the driving member to transmit rotary power from the driving member to the carrier. The torsional vibration damper is coupled to the driving member for rotation therewith. The lubricant is disposed on the remaining portion of the wrap spring.
