Abstract
A controllable rubber bearing with a hydraulic damping device, in which a fluid-filled working space is limited by a plate of magnetizable material. The plate is supported on a spring at least partially. The plate can be moved back and forth in the direction of the working space, as a function of preset parameters, using a magnet system. The support element comprises at least two opposite partial elements at least within the axial expanse of the magnet coil, which are separated from one another by an electrically insulating layer. The insulating layer extends parallel to the direction of motion of the plate and is essentially perpendicular to at least one groove of the support element, which can be made of soft iron or a moldable magnetizable material.
