Abstract
A device for damping torsion oscillations comprises support rotatably movable about an axis. A pendular body comprises first and second axially spaced pendular masses movable relative to the support. The first mass disposed axially on a first side of the support and the second mass disposed axially on a second side of the support. A member connects the first and second pendular masses. Each mass includes an opening in which the connecting member is force-fitted. The openings have radially exterior and interior edges. The connecting member has radially interior and exterior edges. The radially exterior edge extends between two angular ends of the connecting member, each defined by a lug. Each mass exerts a force on each lug, and via a one nose piece projecting radially and carried by the radially interior edge of the opening or the radially interior edge of the connecting member.
