  • Patent number: 12152649
    Abstract: A hydraulically damping assembly bearing has two fluid-filled chambers which lie axially opposite each other and are hydraulically connected by a channel. A first chamber forms a working chamber enclosed by a bearing spring body and a second chamber forms a compensating chamber enclosed by a bellows. The compensating chamber has an axially extending inner wall encircling an interior. The bearing includes an annular body axially between the working and compensating chambers, enclosing an axial throughopening opening into the working chamber and closed by a membrane integrally formed with the inner wall of the bellows. The membrane has a central region defined by the inner wall and together with the inner wall delimits the interior. The membrane has a collar region encircling the central region and integrally formed with the central region. The outer circumference of the collar is rigidly connected to the annular body and/or the spring body.

  • Patent number: 12152651
    Abstract: Rotational translation of an inertial mass rotor is used for providing damping of low frequency noise and vibration. An axial component is mounted so as to translate axial movement of an inertial linearly-displaceable member to rotational movement of an inertial mass rotor. The translation to rotational movement of the inertial mass rotor provides inertial amplification in the form of translational-rotational coupling. This enables the construction of a compact assembly, which allows light ultra-low frequency resonances to be concentrated, and which absorbs such low frequency noise energy.
