Abstract
A torsional vibration isolator for a motor vehicle includes an input member having an engine drive component. An output member defines a transmission input shaft. A component group connecting the input member to the output member includes a first spring engagement element connected to a ring gear. At least one pinion gear is engaged to the ring gear. A sun gear is engaged to the at least one pinion gear. A second spring engagement element is connected to a carrier, the carrier also connected to the at least one pinion gear. At least one spring contacts both the second spring engagement element and the first spring engagement element to permit the second spring engagement element and the carrier to angularly deflect with respect to the first spring engagement element.
