DEVICE FOR DAMPING TORSIONAL OSCILLATIONS

摘要

A device for damping torsional oscillations, comprising:
a support capable of moving rotationally around an axis;a plurality of pendulum bodies, each pendulum body being movable with respect to the support; anda plurality of bearing members, each bearing member interacting with a first raceway integral with the support and with at least one second raceway integral with a pendulum body, the movement of each pendulum body with respect to the support being guided by two of those bearing members,the support comprising a plurality of windows in each of which two bearing members are received, one of those bearing members interacting with at least one second raceway integral with one of the pendulum bodies, and the other of those bearing members interacting with at least one second raceway integral with another of those pendulum bodies, the pendulum bodies being circumferentially adjacent.

1. A device (1) for damping torsional oscillations, comprising:
a support (2) capable of moving rotationally around an axis (X); a plurality of pendulum bodies (3), each pendulum body (3) being movable with respect to the support (2); and a plurality of bearing members (11), each bearing member (11) interacting with a first raceway (12) integral with the support (2) and with at least one second raceway (13) integral with a pendulum body (3), the movement of each pendulum body (3) with respect to the support (2) being guided by two of those bearing members (11), the support (2) comprising a plurality of windows (19) in each of which two bearing members (11) are received, one of those bearing members (11) interacting with at least one second raceway (13) integral with one of the pendulum bodies (3), and the other of those bearing members (11) interacting with at least one second raceway (13) integral with another of those pendulum bodies (3), said pendulum bodies (3) being circumferentially adjacent.
