Abstract
A decoupler that includes a drive member, a hub and an isolator that is configured to transmit rotary power between the drive member and the hub in a predetermined rotational direction. The isolator includes a wrap spring, a plurality of helical coil springs, and a carrier assembly. The wrap spring includes a plurality of helical coils and a proximal end. The helical coil springs are disposed between the hub and the carrier assembly. The carrier assembly includes a carrier plate and a spring shell. The carrier plate has a plate member with a rim and a spring groove. The rim abuts an axial end of the wrap spring. The proximal end of the wrap spring is received in the spring groove. The spring shell is assembled to the carrier plate and has a toric inner surface into which the helical coil springs are received.
