Abstract
An isolator decoupler comprising a first tapered portion for connecting to a driving shaft, a second tapered portion cooperatively engaging the first tapered portion, the second tapered portion having a frictional engagement with a pulley, and an elastomeric member operatingly disposed between the second tapered portion and the pulley.
Claims6
An isolator decoupler comprising:
- a first wedge disk (10) having a first tapered portion (11);
- a second wedge disk (20) having a second tapered portion (21) cooperatively engaging the first tapered portion, the second wedge disk attached to a first hub member (30);
- the first wedge disk normally having a frictional engagement with a plate member (40), the first wedge disk disengaging the plate member upon relative axial movement of the first wedge disk toward the second wedge disk;
- a spring (60) disposed between the first wedge disk and the second wedge disk;
- and
- an elastomeric member (70) operatingly disposed between the second wedge disk and a pulley (50).
