Abstract
A decoupler having a hub, a drive member and an isolator. The drive member is disposed about the hub for rotation about a rotational axis and includes an inner clutch surface. The isolator couples the hub and the drive member and includes a carrier, a plurality of arcuate springs, and a wrap spring. The carrier is received between the hub and the drive member and includes a carrier member, which defines a pair of apertures, and a pair of reaction blocks that are mounted in the apertures. The arcuate springs are mounted in the carrier member and are disposed between the hub and an associated one of the reaction blocks. The wrap spring has an end and a plurality of helical coils that are engaged to the inner clutch surface of the drive member. The end has an end face that is abutted against one of the reaction blocks.
