Vibration attenuation/damping device for motor vehicle, has elastomeric studs distributed along sub-side of base of lower part, to modify orthogonal components from radial effort generated by excentric mass

摘要

The device has a unique motor (5) associated to a unique excentric mass (7) provided on a rotating shaft (50). Elastomeric studs (210) are fixed on a reception structure and are distributed along a sub-side of a base (211) of a lower part (21), so as to modify the orthogonal components from the radial effort generated by the excentric mass, where the part (21) receives two shells (22, 23).
