Abstract
In an aspect, an isolator is provided for isolating a device driven by an engine via an endless drive member. The isolator includes a shaft adapter that is connectable with a shaft of the device, a rotary drive member that is engageable with the endless drive member, a first isolation spring arrangement that is positioned to transfer torque between the shaft adapter and the rotary drive member, and a position-based damping structure. The damping structure is positioned to transfer torque via a frictional damping force between the rotary drive member and the shaft adapter at a selected amount of relative movement therebetween. The selected amount of relative movement is selected to be less than a maximum permitted amount of flexure of the first isolation spring arrangement.
