PENDULAR DAMPING SYSTEM EQUIPPED WITH A SUPPORT MEMBER HAVING CONTINUOUSLY CONTINUOUSLY RUNNING ROLLING PISTES AROUND THE AXIS OF ROTATION

摘要

The invention relates to a vibration damping system for a motor vehicle transmission comprising: - a support member (1) adapted to be rotated about an axis X and having a plurality of external raceways (16 ); and a plurality of pendulum weights (2) circumferentially distributed around the X axis; each of the pendulum weights (2) being mounted oscillating relative to the support member (1) by means of two rolling bodies (12, 13) which cooperate respectively with one and the other of the two inner raceways (14, 15) of said pendulum weight (2) and each cooperate with one of the outer raceways (16) of the support member (1); - The outer raceways (16) are juxtaposed one after the other continuously around the axis X so that the rolling bodies (12, 13) are each able to freely pass a first raceway external (16) to a second outer race (16).
