Abstract: The invention relates to a switchable assembly bearing that comprises at least one working chamber and one compensation chamber which are separated by a dividing wall. The working chamber and compensation chamber are hydraulically interconnected by means of a damping channel, in addition to at least one other damping channel which can be closed by means of the sealed arrangement of a shut-off body which can be displaced along a displacement path. The other damping channel is formed and arranged in relation to the axis of symmetry of the bearing in such a way that the forces acting on the shut-off body by means of the hydraulic fluid counterbalance each other.

Abstract: The invention relates to an assembly bearing with hydraulic damping, especially for supporting engines and/or gearboxes in motor vehicles. Said bearing comprises a working chamber (10) and a compensation chamber (20) which respectively have partially elastically deformable walls (30, 40) and are separated by a dividing wall (50), but interconnected by means of a damping channel (60) through which a fluid is guided, in addition to another passage opening (14) which can be variably adjusted from outside. According to the invention, a decoupling device for insulating high-frequency, low-amplitude vibrations is provided in the dividing wall (50), the other passage opening (14) being arranged upstream or downstream of said decoupling device.

Abstract: A hydraulic two-chamber bearing for damping vibrations, in particular an engine mount on motor vehicles, having an engine-mount plate, a bearing spring made of rubber-elastic material, a working chamber and a compensation chamber for the liquid which are separated from each other by a partition provided with flow-through openings, and an elastic pressure diaphragm which terminates the compensation chamber, characterized in that the amount of fluid flowing through the openings (6) of the partition (5) is controlled as a function of the amplitude (A) of the vibrations.

Abstract: A mount, for example for mounting an engine in a vehicle, has a resilient vibration isolator and, separate therefrom, an electro-magnetically controllable vibration-damping arrangement. In this way, the damping can be controlled independently of the isolation, for example in response to the amplitude of the vibrations only to isolate resiliently small-amplitude vibrations, but damp fully large-amplitude, road-bump vibrations which could damagingly shake the engine.

Abstract: A mount for connecting two relative-vibratable objects has two resilient elements and a signal actuated clutch for connecting the objects. The clutch is in parallel with one of the resilient elements and in parallel with the other. A sensor senses the vibrations applied across the mount and actuates the clutch in response thereto to change the transfer function of the mount. Appropriately controlling the engagement/disengagement actuation of the clutch in this way makes it possible to avoid the resonant frequencies of the mount and thus both isolate and damp the vibrations as desired without structural changes to the mount.
