Abstract:
1. 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 directly interconnected with the output of the engine and including at least one retaining member; a centrifugal pendulum vibration absorber including at least one mass supported by the retaining member of the first member, wherein the mass defines an aperture having an aperture surface engaged with the retaining member of the first member, wherein the mass absorbs vibrations through the first member from the engine to the transmission at a first range of engine speeds; a resilient vibration absorber including at least one biasing member having a first end and a second end, wherein the second end is interconnected with the input of the transmission and the biasing member deforms at a second range of engine speeds; and a torque transmitting device having an input interconnected with the first member and an output interconnected with the first end of the resilient vibration absorber, and wherein the speeds of the second range are lower than the speeds of the first range of engine speeds.
