Title: PENDULUM DAMPING DEVICE
Abstract:
Pendulum damping device (1) comprising: - a support (2) capable of rotating about an axis (X); - at least one pendulum body (3) comprising: a first and a second pendulum mass (5) axially spaced apart from each other and movable relative to the support (2), the first pendulum mass (5) being axially arranged on a first side (4) of the support (2) and the second pendulum mass (5) being axially arranged on a second side (4) of the support (2), and at least one link member (6) of the first and of the second pendulum masses (5) joining said masses; and - at least one rolling member (11) guiding the displacement of the pendulum body (3) relative to the support (2), the rolling member (11) having a portion (31) with a surface capable of simultaneously rolling on a first raceway rigidly connected to the support (2) and on a second raceway (13) defined by the link member (6), the rolling member (11) and the link member (6) having facing surfaces directly cooperating so as to limit the axial displacement of the rolling member (11) relative to the link member (6).
