Abstract
A torsional vibration damper with a V-belt pulley unit (Front power take-off) attached to the primary part of the damper. In order to increase the service life of the damper and to improve the level of loading in the front PTO, the V-belt pulley is mounted radially and axially on a support element that is connected to the primary part of the damper. A specially designed coupling element, which contains an elastomer that has a high degree of torsional elasticity, is used in conjunction with the axial bearing. In this way, a supercritical adjustment is attained for the vibration system of the PTO, the vibration damper itself being used only for damping the torsional vibrations of the engine crankshaft.
