Definitions
- FIG. 10 shows a torsional vibration damping arrangement according to the invention.
- Figures 1 to 5 show a torsional vibration damping arrangement 1 in which a stop element 5 of the cover plate 3 is integrally executed. It is to be understood here integrally that the stop element is formed from the cover sheet and was not connected to the cover sheet by a connecting process.
- the stop element 9 of the secondary mass 8 is designed here as a separate component which is connected to the secondary mass 8 by means of a riveting process.
- FIG. 2 shows the cover plate 3 and the secondary mass 8 in a rest position, the cover plate 3 being able to be rotated by an angle c to the secondary mass 8.
- FIG. 3 shows components as in FIG. 2, but here the cover plate 3 is maximally rotated to the secondary mass 8, so that the stop elements 5 and 9 are in contact, so that further rotation of the cover plate 3 to the secondary mass 8 is prevented becomes.
- FIG. 6 to 10 show a torsional vibration damping arrangement 1 in which a stop element 5 of the cover plate 3 and the stop element 9 of the secondary insulation mass 8 are integrally executed.
- FIG. 7 shows the cover plate 3 and the secondary mass 8 in a rest position, the cover plate 3 being rotatable by an angle c to the secondary mass 8.
- FIG. 8 shows components as in FIG. 7, but here the cover plate 3 is maximally rotated to the secondary mass 8, so that the stop elements 5 and 9 are in contact, so that a further rotation of the cover plate 3 to the secondary mass 8 is prevented .
