ABSTRACT:
The present invention is concerned with a double damped flywheel of the kind having springs (40), at least one damper plate (30) and guide rings (17, 18). The double flywheel is characterized by a phasing device having thrust pads each of which is interposed circumferentially between two consecutive ones of the resilient springs, the phasing device being mounted for free rotation with respect to the guide rings. The damper plate is centered directly or indirectly by one of the guide rings or by the damper plate in such a way as to divide each of the resilient springs into two operative elements. The double damped flywheel further comprises inserts mounting the resilient springs pivotally on the thrust pads.
