a fluid filled schwingungsdu00e4mpfungsvorrichtung with a druckaufnahmekammer whose federsteifigkeit is controllable

摘要

in a fluid filled schwingungsdu00e4mpfungsvorrichtung (10, 84) are two related beabstandete montageelemente (12, 14) by an elastic body (16), with an elastic wall (42), and partly a druckaufnahmekammer (56, 64, 86).and a flexible membrane (34) interaction, which partly ausgleichskammer (38) at one side and a arbeitsluftkammer (40) on the other side are defined. these chambers are filled with a zusammendru00fcckbaren fluid and are in a fluidverbindung together by a u00f6ffnungsdurchtritt (68).a unterdruckregelvorrichtung (76, 78, 80, 82) brings a different negative pressure on the arbeitsluftkammer depending on the frequencies of dampening vibration, so that a federkonstante of elastic wandelementes in accordance with the dampening vibration. change, as a du00e4mpfungskenlinie the du00e4mpfungsvorrichtung to taxes.
