  • the torsional vibration damper 5 according to the present embodiment is a dual mass flywheel (DMF).
  • Torsional vibration damper and dual clutch form the torque transfer device between the drive and transmission.
  • the torsional vibration damper 5 comprises an input part 6, which is also referred to as a primary flywheel or short primary mass.

  • the toothing fingers 11 D have a connection region 11D3 with the annular region 11C, a neck region 11D1 and a head region 11D2, wherein the head region 11D2 engages in a counter-toothing 12A of a toothed rim 12.
  • the ring gear 12 is connected via a rivet connection with a driver ring 13.

  • the present invention is not limited to the embodiment shown in FIGS. 1 to 3 with ZMS and dual clutch. Rather, the use of a one-piece flywheel and / or a single clutch would be possible.
  • connection described above is characterized by the arrangement of "soft" Veriereungsfingern 11 D in the radial direction, so that axial space is saved.

  • the fingers are inserted as accurately as possible in a counter toothing on the double clutch.
  • tolerance variations in the position of the finger-tip zen (due to usual manufacturing tolerances) ensure that a tension in the circumferential direction is present, so that no gearing rattling occurs.

  • toothed fingers and the tabs can be formed together either on the output part of the DMF or on the driving plate of the coupling, in which case the counter toothing and the window regions would be formed together on the corresponding other component.
  • toothed fingers (for example, alternating) may be formed on the output part of the DMF and on the driving plate of the coupling, wherein at the same time tabs and window areas may be formed on the output part and on the driving plate.
  • the output flange includes the elastic toothing fingers and is also used at the same time to control the bow springs and the driving ring at the same time includes or carries the counter-profiling.
  • This type of connector is particularly useful between bow springs, dampers and dry double clutch.
  • the comparatively "soft" toothed fingers also referred to as “spring fingers” can be inserted at their tips in an exact fit in a counter toothing.
  • spring fingers have tolerances in their positions due to production, changes in the torque to be transmitted will never change all spring fingers at once the contact side. This is a gearing rattle effectively avoided.
  • stiffer areas the lobes that engage when the torque to be transmitted exceeds a design-dictated range, or when an anticipated twist is exceeded.
