Abstract:
A torsional vibration damper, comprising:a first damper element;a second damper element rotatable relative to the first damper element around a rotational axis;first damping spring means for connecting the first and the second damper elements for torque transmission, the first damping spring means including at least one damping spring arrangement which extends in approximately a circumferential direction and has at least one damping spring;support means for supporting the damping spring arrangement, the support means being provided on the first damper element, the support means including support elements which support end areas of the spring arrangement in a substantially circumferential direction, the first damper element having a displacement surface for each support element, along which displacement surface a correspondingly configured displacement surface of the associated support element is movable in the circumferential direction;respective carrier means on the second damper element for each of the support elements for carrying the support elements along on the first damper element for displacement movement of the support element along the associated displacement surface, and pressing the respective support element toward the displacement surface, upon relative rotation between the first and the second damper elements; anda lubricant chamber in a region of the displacement surface, which lubricant chamber is sealed at least radially and contains a lubricant therein.
