Abstract
In an aspect, a decoupler is provided, comprising a hub defining an axis, a pulley, a one way clutch and an isolation spring that act in series, a damping member that frictionally engages a friction surface the pulley or the hub, and a biasing member that urges the damping member into the friction surface. The biasing member has a mounting portion having an axially extending first mounting surface that is fixedly engaged with a second axially extending mounting surface on the other of the pulley and hub and an engagement portion resiliently connected to the mounting portion by a transition portion having at least one bend that urges the engagement portion into engagement with the damping member with a selected force. The at least one bend resiliently permits axial movement of the damping member engagement portion independent of the mounting portion.
