A centrifugal-force pendulum device having a pendulum flange and at least two pendulum masses fastened on both sides of the pendulum flange by means of a spacer bolt received in a cut-out of the pendulum flange to form a pendulum mass pair, wherein the pendulum mass pair is guided and pivoted in a limited manner with respect to the pendulum flange by means of at least two rolling elements, and the rolling elements are received and roll in guide tracks in the pendulum masses and in complementarily shaped guide tracks in the pendulum flange, and wherein the spacer bolt is equipped, in its axial region which reaches through the cut-out in the pendulum flange, with damping means for damping contact of the spacer bolt against the cut-out, and compression of the damping means is limited by contact of a rolling element against the guide track which receives the rolling element.
A method of damping vibration with a centrifugal pendulum device including a pendulum flange, a first pendulum mass and a second pendulum mass arranged on a first side and a second side of the pendulum flange, respectively, a first spacer bolt and a second spacer bolt fixed to the first and second pendulum masses, respectively, and passing through a first recess and a second recess in the pendulum flange, respectively, a first roller element passing through a first guide track in the flange and accommodated in a second guide track and a third guide track in the first and second pendulum masses, respectively, a second roller element passing through a fourth guide track in the flange and accommodated in a fifth guide track and a sixth guide track in the first and second pendulum masses, respectively, a first damping sheath disposed about the first spacer bolt, and a second damping sheath disposed about the second spacer bolt, the method comprising:
