| 摘要 |
This torsion damping device having a pendulum comprises oscillating masses (6, 8, 10) that are mounted in a movable manner on a holder (4). Each oscillating mass (6) is interposed circumferentially between a first adjacent oscillating mass (8) and a second adjacent oscillating mass (10). Each oscillating mass (6) is mounted in a movable manner on the holder (4) by means: - of a rolling contact that rolls via a single rolling bearing element (12) associated with this oscillating mass; - of a sliding contact that slides between one of the end edges (18) thereof and an end edge (20) of the adjacent second oscillating mass (10), which forms an edge for radially retaining this oscillating mass (6). The device makes it possible to achieve effective pendular damping with a limited number of rolling bearing elements. |
