Isolator assembly and a vehicle including the isolator assembly
An isolator assembly includes a clutch configured to operate in a full locked condition and a slip condition. Additionally, the isolator assembly includes a damper and a centrifugal pendulum absorber (CPA). The damper is configured to reduce oscillation when the clutch is in one of the full locked condition and the slip condition. The damper includes a blade that is biasable. The CPA is coupled to the damper and configured to reduce oscillation when the clutch is in one of the full locked condition and the slip condition. A vehicle includes an engine and a transmission. The engine includes an output shaft and the transmission includes an input member. The vehicle includes the isolator assembly operable between the output shaft and the input member.

6. The assembly as set forth in claim 1 wherein the CPA is coupled to the damper downstream from the blade relative to a direction that torque is transferred across the isolator assembly.
7. The assembly as set forth in claim 6 wherein the damper includes a pair of side plates spaced from each other, with the blade disposed between the side plates, and wherein the CPA is directly attached to one of the side plates.
8. The assembly as set forth in claim 7 wherein the clutch is disposed upstream from the damper and the CPA relative to the direction that torque is transferred across the isolator assembly.
9. The assembly as set forth in claim 7 wherein the clutch is disposed downstream from the damper and the CPA relative to the direction that torque is transferred across the isolator assembly.
10. The assembly as set forth in claim 1 wherein the CPA is further defined as a first CPA, and further including a second CPA spaced from the first CPA such that the blade is disposed between the first CPA and the second CPA.
11. The assembly as set forth in claim 10 wherein:
the damper includes a pair of side plates spaced from each other, with the blade disposed between the side plates;
the first CPA is directly attached to one of the side plates;
the damper includes a roller disposed between the side plates and the roller engages the blade; and
the second CPA is directly coupled to the roller through the other one of the side plates.
12. The assembly as set forth in claim 11 wherein the clutch is disposed upstream from the damper, the first CPA and the second CPA relative to a direction that torque is transferred across the isolator assembly.

wherein the pump is operable upstream from the clutch relative to a direction that torque is transferred across the isolator assembly.
15. The assembly as set forth in claim 14 wherein the clutch is disposed upstream from the damper and the CPA relative to the direction that torque is transferred across the isolator assembly.
16. The assembly as set forth in claim 14 :
further including a casing that houses the pump, the turbine, the damper, the CPA and the clutch;
wherein the damper includes a connector spaced from the CPA; and
wherein the connector of the damper is coupled to the casing.
