DEVICE FOR DAMPING TORSION OSCILLATIONS, NOTABLY FOR A MOTOR VEHICLE TRANSMISSION SYSTEM

摘要

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.

1. Device (1) for damping torsion oscillations, comprising:
a support (2) able to move in rotation about an axis (X), at least one pendular body (3) comprising: first and second pendular masses (5) spaced axially relative to each other and mobile relative to the support (2), the first pendular mass (5) being disposed axially on a first side (4) of the support (2) and the second pendular mass (5) being disposed axially on a second side (4) of the support (2), and at least one member (6) connecting the first and second pendular masses (5) matching said masses and force-fitted thereto,each pendular mass (5) including an opening (7) in which the connecting member (6) is force-fitted, this opening having a radially exterior edge (47) and a radially interior edge (40), and the connecting member (6) having a radially interior edge (30) and a radially exterior edge (31), said radially exterior edge (31) extending between two angular ends (33) each defined by a lug (34) of the connecting member (6),each pendular mass (5) exerting on the connecting member (6) force-fitted in its opening (7):
a force (F3, F4) on each lug (34) of the connecting member (6), and a force (F1, F2) via at least one nose piece (42) projecting into the opening (7) and carried by either the radially interior edge (40) of the opening (7) or the radially interior edge (30) of the connecting member (6).
