Abstract:
A system for absorbing vibration created by operation of an engine of the present invention includes a first plate driven by an engine shaft and a torque transmitting device for transferring torque from the engine shaft to a transmission input shaft. The system includes a first vibration absorber and a second vibration absorber. The first vibration absorber includes at least one selectively moveable mass. The second vibration absorber includes at least one biasing member and generally opposing ends. The first vibration absorber is configured to absorb vibrations created at a first harmonic of the engine and the second vibration absorber is configured to absorb vibrations created at multiple harmonics of the engine.
