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.

Claims (17)

1. 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 ).

2. The isolator decoupler as in claim 1 , wherein the spring comprises a coil spring.

3. The isolator decoupler as in claim 1 , wherein the first tapered portion is situated at an angle α relative to a plane which extends normal to an axis of rotation (A-A).

4. The isolator decoupler as in claim 1 , wherein the first tapered portion, the second tapered portion and the elastomeric member are contained within the pulley.

5. The isolator decoupler as in claim 1 further comprising a second hub member attached to the first hub member.

6. 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 ), the second wedge disk attached to a first hub member ( 30 );

the first tapered portion is situated at an angle α relative to a plane which extends normal to an axis of rotation (A-A);

the second tapered portion cooperatively engaging the first tapered portion;

a spring ( 60 ) disposed between the first wedge disk and the second wedge disk, the first wedge disk disengaging the plate member upon relative axial movement of the first wedge disk toward the second wedge disk; and

the first wedge disk normally having a frictional engagement with a plate member ( 40 ) and contained within a pulley ( 50 ).
