Centrifugal pendulum absorber

The invention relates to a centrifugal pendulum absorber for a flywheel, including,

A pendulum weight for a centrifugal pendulum absorber for a flywheel of a vehicle includes a bearing surface that, when the pendulum weight is mounted radially outside of a central axis of the pendulum absorber, cooperates with a corresponding bearing surface provided on a separate part of the pendulum absorber, with respect to which separate part the pendulum weight is thereby configured to be movable along a predetermined pendulum path. The pendulum weight further includes a pocket formed in connection with the bearing surface, the pocket being configured to receive at least a portion of the separate part when the pendulum weight moves along the pendulum path. The pendulum weight includes an outward portion and a separate inward portion which are assemblable to form the pendulum weight, the outward portion being configured to be located radially outside of the inward portion with respect to the central axis when mounted.
