Rotational vibration attenuation device e.g. for rotational vibration absorption, has primary and secondary mass with secondary mass has opposite effect of one rotary vibration damping element

摘要

The torsional vibration attenuation device (1) has a primary and secondary mass (4, 5). The secondary mass has an opposite effect of one rotary vibration damping element (7). A bearing (10) is provided with an axial thrust washer (18) with an axial friction (16), and a radial bearings sleeve (14) included and twistable relative to the primary mass. The axial thrust washer (18) is connected with a circuit with the primary mass.
