TORSIONAL VIBRATION DAMPER HAVING A CENTRIFUGAL PENDULUM ABSORBER AND PRE-DAMPER

摘要

The invention relates to a torsional vibration damper (1) in the form of a dual-mass flywheel having a primary part (2) and a secondary part (3) which are rotatable about a rotational axis and can be twisted relative to one another and which are connected via a damping device (4) that includes bent springs, wherein the bent springs are supported with one end on stops of the primary part (2) and with a further end on flange wings (7) of a support flange (5) associated with the secondary part (3), to which support flange pendulum masses (22) of a centrifugal pendulum absorber (25) are fastened and are arranged so as to be movable on either side, and the torsional vibration damper (1) includes, in a manner circumferentially spaced apart from the pendulum masses (22), a pre-damper (10) connected to the support flange (5).
