Abstract
A torsional vibration damper having a first damper element and a second damper element, which are connected to each other for the purpose of torque transmission by a first damping spring device. The first damping spring device has at least one damping spring arrangement with at least one damping spring. One of the damper element has a support on which the damping spring arrangement is supported in its respective end areas in approximately the circumferential direction via support elements. Further, a displacement surface is embodied on the first damper element for each support element. On the other damper element, there are carriers for each support element. Upon a relative rotation between the first and second damper elements, the carrier serve to take along the respective support elements and press them in the direction of the displacement surface for the purpose of movement along the associated displacement surface. At least in the area of the displacement surface, there is a lubricant chamber sealed at least toward the radial outside and with lubricant located therein.
