Abstract:
A torsional vibration damper for torsional vibration damping in a drive train of a motor vehicle is provided with a primary mass for introducing a torque, wherein the primary mass has a flywheel which can be connected to an input shaft, a secondary mass which can be rotated to a limited extent relative to the primary mass for dissipating a torque, an energy storage element that can act on the primary mass and on the secondary mass and a centrifugal pendulum connected to the secondary mass to provide restoring torque directed against a rotational irregularity, wherein the centrifugal pendulum is arranged in the axial direction between the flywheel of the primary mass and the energy storage element. By arranging the centrifugal pendulum between the flywheel of the primary mass and the energy storage element, otherwise free installation space on the outside can be used for better vibration damping behavior, while on the inside an increase in the axial installation space requirement is avoided, so that good damping is made possible in a drive train with a small installation space requirement.
