Patent ID: 8276720

Claim:
A damper for a vehicle drivetrain having a clutch comprising: a first cover; a second cover; a first vibration pathway having a natural frequency, said first vibration pathway including a first inertial element disposed between a first pair of elastic elements, wherein one of said first pair of elastic elements is operatively connected to said first cover and the second of said first pair of said elastic elements is operatively connected to said second cover; and, a second vibration pathway having a natural frequency, said second vibration pathway including a second inertial element disposed between a second pair of elastic elements, wherein one of said second pair of elastic elements is operatively connected to said first cover and the second of said second pair of said elastic elements is operatively connected to said second cover; wherein said second vibration pathway is substantially parallel to said first vibration pathway; and, wherein the natural frequency of said first vibration pathway is lower than said natural frequency of said second vibration pathway.
