Abstract:
A torsional vibration damper, comprising:two transmission elements which are rotatable relative to one another about a common axis of rotation;coupling elements displaceable between the transmission elements along at least one guide path in a circumferential direction and in a working connection with the two transmission elements so as to permit relative movement between the transmission elements, the guide path being provided on at least one of the transmission elements so as to have a curvature with varying distance from the axis of rotation and a curvature location having a maximum distance from the axis of rotation, the coupling elements including a coupling body provided at another of the transmission elements so as to be received by the guide path, the coupling body having a rolling area facing the guide path, with its own curvature; anda path body of predetermined elasticity provided on one of the guide path and the coupling body at least along a partial area of the respective curvature so that when loaded by an other of the guide path and the coupling body a deformation is achieved for adapting the curvature shape of the path body to the curvature of the other of the guide path and the coupling body, the path body having a thickness along its length that varies so as to influence elasticity.
