ABSTRACT:
A torsional vibration damper is provided with a transmission element on the driving side, at least one planet carrier which is provided with at least one bearing for receiving a planet gear engaging with at least one ring gear, and a transmission element on the driven side. One of the transmission elements has a controller for elastic elements of a damping arrangement. At least one lubricant feed is associated with the planet gear. The lubricant feed extends, at least along part of its extent, within the range of extension of the planet gear and opens out in the region of the bearing. Lubricant can flow through this lubricant feed due to the pumping action of the planet gear as it rotates relative to other elements of the planetary gear unit.
