Abstract

A torsional vibration damper for a drivetrain of a motor vehicle having a substantially discoidal centrifugal flange and a plurality of centrifugal pendulum-type absorbers. Each centrifugal pendulum-type absorber includes a first pendulum mass and a second pendulum mass. The first pendulum mass is arranged above a first surface of the pendulum flange, and the second pendulum mass is arranged above a second surface of the pendulum flange. The first pendulum mass and the second pendulum mass are firmly connected to each other by means of at least two spacing bolts in each case. The pendulum flange has a plurality of cutouts in which the spacing bolts are guided. A second spacing bolt of a first centrifugal pendulum-type absorber and a first spacing bolt of a second centrifugal pendulum-type absorber are guided in at least one first cutout.
