Abstract: In an aspect, a tensioner is provided for tensioning a belt and includes first and second tensioner arms having first and second pulleys respectively. The first and second pulleys are configured for engagement with first and second belt spans, and are biased in first and second free arm directions respectively. A second tensioner arm stop is positioned to limit the movement of the second tensioner arm in a direction opposite the second free arm direction. The second tensioner arm stop is positioned such that, in use, the second pulley is engaged with the endless drive member while the second tensioner arm is engaged with the second tensioner arm stop throughout a first selected range of operating conditions.

Abstract: In an aspect, a power transfer device, such as a decoupler, is provided for transferring torque between a shaft and a belt. The device includes: a hub configured to couple to the shaft, a pulley rotatably coupled to the hub that includes a power transmitting surface configured to engage the belt, an isolation spring to transfer a rotational load from one of the pulley and the hub to the other of the pulley and the hub, optionally a one-way clutch to permit overrunning of one of the pulley and the hub relative to the other of the pulley and the hub in a first direction, and a damping member positioned to be driven into frictional engagement with a friction surface by a force from the isolation spring acting on the damping member that varies based on the rotational load transferred by the isolation spring.

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.
