Torsional vibration damper with a planetary gearset

Torsional vibration damper in particular for clutches on motor vehicles, with a driving-side transmission element with at least one planet wheel which is engaged with a ring gear, and with a driven-side transmission element, whereby one of the transmission elements has actuating means for a spring device, wherein both the driving-side transmission element and the driven-side transmission element each have a centrifugal mass, at least one of which is connected by means of the spring device to at least one of the following elements:

• a planet carrier, and the ring gear;
• the at least one element acting as an intermediate mass, whereby the intermediate mass can be driven in a movement which is a function of the speed and direction of rotation of the two centrifugal masses in relation to one another;
• one of the centrifugal masses, on its side facing the other centrifugal mass, has an axial motion retainer for the latter centrifugal mass;
• and
• the motion retainer is formed by a friction ring, the distance of which from the axis of the clutch is a function of the basic friction required.

• one of the centrifugal masses has a chamber which is at least partly filled with a pasty medium, and is designed with actuator elements for the spring device located in the chamber, which spring device is supported on the other end on the planet carrier;
• and
• said torsional vibration damper further comprising one of the following sets of features (C) and (D):
• (C) that the planet carrier and planet wheel, and ring gear of the planetary gearset are located in a recess provided between the chamber and the other centrifugal mass;
• and
• (D) that the chamber is designed in the axial direction so that it is large enough to hold at least the ring gear and planet wheel of the planetary gearset.
