Abstract
A torsional vibration damper includes a pendulum flange which is rotatable around an axis of rotation, having a cutout, as well as two pendulum mass pairs which are movably attached to the pendulum flange, adjacent to each other in the circumferential direction, and an elastic element to damp mutual colliding of adjacent pendulum mass pairs. The pendulum mass pairs each comprise two pendulum masses which are positioned opposite each other relative to the pendulum flange, and a bolt which runs through the cutout and connects the pendulum masses to each other axially. In the area of the cutout an elastic element is attached to each of the two bolts, which is set up to collide with the other elastic element in the circumferential direction.
