Abstract
A system includes a stationary component, a rotating component arranged adjacent the stationary component, and a planetary torsional vibration absorber system mounted between the stationary component and the rotating component. The planetary torsional vibration absorber system includes a planetary gear system including a ring gear, a sun gear and a carrier. At least one of the ring gear, the sun gear and the carrier is rotationally fixed to the rotating component and another of the ring gear, the sun gear and the carrier is fixedly secured to the stationary component. A tuned vibration absorber including a tunable damping and stiffness component and an inertia ring is mounted to yet another of the ring gear, the sun gear and the carrier.

A system comprising:
- a stationary component;
- a rotating component arranged adjacent the stationary component;
- and
- a planetary torsional vibration absorber system mounted between the stationary component and the rotating component, the planetary torsional vibration absorber system comprising:
- a planetary gear system including a ring gear, a sun gear and a carrier, at least one of the ring gear, the sun gear and the carrier being rotationally fixed to the rotating component and another of the ring gear, the sun gear and the carrier being fixedly secured to the stationary component;
- and
- a tuned vibration absorber including a tunable damping and stiffness component and an inertia ring mounted to yet another of the ring gear, the sun gear and the carrier.
A vehicle comprising:
- a chassis;
- a prime mover supported in the chassis;
- a transmission operatively connected to the prime mover;
- a rear drive module operatively connected to the transmission;
- a propshaft operatively connecting the transmission and the rear drive module;
- and
- a planetary torsional vibration absorber system mounted between one of the chassis, the transmission, and the rear drive module and the propshaft, the planetary torsional vibration absorber system comprising:
- a planetary gear system including a ring gear, a sun gear and a carrier, at least one of the ring gear, the sun gear and the carrier being rotationally fixed to the propshaft and another of the ring gear, the sun gear and the carrier being fixedly secured to one of the rear drive module, the chassis, and the transmission;
- and
- a tuned vibration absorber including a tunable damping and stiffness component and an inertia ring mounted to yet another of the ring gear, the sun gear and the carrier.
