  • Patent number: 4899996
    Abstract: This invention relates to a hydraulically damping elastic bearing, in particular engine mounts for motor vehicles, with two fastening devices opposite one another, an elastomer resilient body between them, and a controllable electromagnet located on one fastening device, consisting of coil and armature, with which a magnetically active element can interact to change the suspension characteristic of the elastic bearing. To achieve a variable, dynamic damping by way of an electrical control, with simultaneous hydraulic action, the interior of the elastic bearing is divided into two chambers filled with damping fluid. The chambers are connected with one another by means of at least one throttle, whereby the coil and the axially movable armature of the electromagnet are designed partly as the partition between the chambers.
