Patent ID: 8435123

Claim:
An apparatus for absorbing vibration and transmitting a torque between an output of an engine and an input of a transmission of a vehicle, the apparatus comprising: a first member interconnected with the output of the engine and including at least one retaining member and at least one alternate retaining member; a first vibration absorber including at least one mass and at least one alternate mass, the mass supported by the retaining member of the first member and the alternate mass supported by the alternate retaining member of the first member, wherein the mass has a predefined movement path with respect to the first member when the first member is rotating and the alternate mass has a predefined alternate movement path with respect to the first member when the first member is rotating, wherein the mass absorbs a portion of the vibrations through the first member from the engine to the transmission at a first range of engine speeds the alternate mass absorbs a portion of the vibrations through the first member from the engine to the transmission as the alternate mass moves along the alternate movement path at a third range of engine speeds; and a second vibration absorber including at least one biasing member having a first end interconnected with the first member and a second end interconnected with the input of the transmission, wherein the biasing member is selected to absorb a portion of the vibrations through the second vibration absorber from the engine to the transmission at a second range of engine speeds, and wherein the speeds of the second range are lower than the speeds of the first range of engine speeds and the third range of engine speeds are greater than engine speeds of the first range of engine speeds.
