Abstract
A centrifugal pendulum vibration absorber (CPVA) absorbs vibration and transmits a torque between an output of an engine and an input of a transmission of a vehicle. The CPVA includes a plate with at least one retaining member and a first set of vibration absorbers with at least one mass supported by the at least one retaining member. The at least one mass has a predefined movement path with respect to the plate. The CPVA further includes a first torsion vibration damper assembly that connects the CPVA to a turbine of a torque converter that is selectively engaged with engine, and a second torsion vibration damper assembly that connects the CPVA to the transmission. The at least one mass absorbs a vibration of a harmonic order generated by the engine.
