Definitions

  • centrifugal pendulum device comprises a damper mass carrier rotatable about an axis of rotation and at least one absorber mass pair arranged thereon consisting of two absorber masses located axially opposite one another.
  • the absorber mass pair and the absorber mass carrier have raceways in which a rolling element is received, so that the absorber mass pair is limitedly pivotable relative to the absorber mass carrier.
  • the absorber mass is arranged in the axial direction between two absorber mass carriers.
  • This design offers the advantage that the absorber mass carriers lead the absorber mass between them so that the absorber masses can be positioned extremely accurately.
  • the friction device is centered on the absorber mass carrier via an inner diameter of the friction device.
  • the friction device is positioned in a simple manner relative to the absorber mass carrier and ensures a particularly effective deceleration of the absorber masses
  • Fig. 1 a further the friction device 7 for braking the absorber masses 3 is shown.

Abstract

L'invention concerne un système de pendule centrifuge (1) servant à amortir les vibrations de torsion, de préférence dans la chaîne cinématique d'un véhicule automobile, comprenant au moins un support de masses d'amortissement (2) mobile en rotation autour d'un axe de rotation (13) et au moins une masse d'amortissement (3) agencée sur le support de masses d'amortissement (2), la masse d'amortissement (3) pouvant pivoter de manière limitée par rapport au support de masse d'amortissement (2) le long d'un chemin de roulement. Le système est muni d'au moins un dispositif de friction (7) et le dispositif de friction (7) peut être mis en contact avec la masse d'amortissement (3), de manière à permettre le freinage de la masse d'amortissement (3) par le dispositif de friction (7), au moins dans la dernière partie du chemin de roulement.
