Abstract

In an aspect, a decoupler is provided and includes an input member, an output member, a one-way clutch and an isolation spring. The one-way clutch receives torque from the input member. The isolation spring is helical, having a first helical end and a second helical end, and has first and second axial ends, and radially outer and inner surfaces. The isolation spring receives torque from the clutch, and transmits torque to the output member. The isolation spring changes size radially based on torque. The input member includes a radial projection that is positioned to frictionally engage one of the radially outer and inner surfaces of the spring when the spring reaches a selected size. Frictional engagement of the radial projection with the spring generates torque transfer directly from the input member to the spring in parallel with torque transfer from the input member to the spring through the clutch.
