Vibrations reduction device e.g. for noise reduction in motor vehicles, has hub on which are mounted vibration suppressing masses

摘要

A vibration suppressor is designed for mounting on a cardan shaft, and comprises a hub (1) on which via at least one first elastomer region (2), is mounted a first vibration suppressing mass (3) where the hub (1) is designed with three flange arms (9,10,11). The hub (1) carries a second vibration suppressing mass (5), via a second elastomer region (4), and the second mass is movable relative to the first vibration suppressing mass (3), and the elastomer regions (2,4) are arranged on inverting/reversing parts (12) between the flange arms (9,10,11).
