An elastomer bearing has an inner part, an outer sleeve that surrounds the inner part, and an elastomer body that is arranged between the inner part and the outer sleeve. The elastomer body extends from the inner part as far as the outer sleeve. The elastomer body comprises two liquid chambers, which are filled with a liquid and arranged one on top of the other in an axial direction, and a duct carrier arranged radially between the elastomer body and the outer sleeve. The duct carrier surrounds the elastomer body in a region of the liquid chambers and bounds the chambers. The elastomer body is vulcanized to the inner part. To reinforce the elastomer body, two, annular reinforcement inlays are embedded in the elastomer body, and form parts, separate from one another, of a cage that is embedded in the elastomer body.

Elastomer bearing

A hydraulically damping rubber bearing has a substantially hollow-cylindrical inner portion and an outer portion disposed with a predetermined spacing relative to the inner portion. A resilient connection portion is disposed between the inner portion and the outer portion and connects the outer portion to the inner portion. The resilient connection portion has a first hydraulic damping circuit with at least two first fluid chambers which are in fluid communication with each other by means of a first flow connection. The first hydraulic damping circuit has a damping action in a predetermined direction. A second hydraulic damping circuit provides a damping action in the same predetermined direction as the first hydraulic damping circuit.

A sleeve bearing for being received in an outer sleeve includes an inner part which extends in the axial direction, a bearing body, and a cage which encloses the bearing body circumferentially. The bearing body encloses the inner part, is made from an elastic material, and has at least two chambers. The cage is formed from at least two cage parts, the spacing of which can be varied in the radial direction. A sealed joint area is provided between the cage parts.

Sleeve bearing

A bearing body () is divided in the radial direction (r) by at least one insert () arranged in the bearing body () parallel to the bearing axis () into at least two spring packets () having an outer switching packet (). Each of the working chambers (') is divided into several chamber sections (-) extending in the radial direction (r) and into at least one chamber section () extending in the axial direction (a) and connecting the chamber sections (-) with one another. The elastomeric bearing body () is segmented in the switching packet () in the axial direction (a) by the chamber sections (-) protruding into the elastomeric bearing body ().

Elastomeric plain bearing having switchable rigidity

A controllable hydraulic bearing for damping vibrations in a defined frequency band is proposed, which includes an elastomeric body (), two chambers which are filled with a magneto-rheological fluid and connected with one another by at least one channel (), with the chambers having at least partially flexible chamber walls, wherein the buckling spring rate of the chamber walls represents a measure for a pressure change due to the volume displacement between the chambers, and at least one electromagnet which generates a magnetic field in the region of the channel (). According to the invention, the magnetic field in the region of the channel () is an inhomogeneous magnetic field.

The invention relates to a stop element () for a hydraulic bearing and a hydraulic bushing equipped therewith. The proposed hydraulic stop element () with a stop body (') and a stop surface () is implemented as a piston-cylinder-assembly with an elastomeric bearing () with at least two work chambers for a fluidic damping means. The cylinder () of this piston-cylinder-assembly is inserted into the solid material surrounding the outer surface of a metallic element of the elastomeric support () which delimits the corresponding work chamber (&#x2032;) of the elastomeric bearing () perpendicular to the main load direction (r). A piston (&#x2032;) which forms the stop body with a stop surface () is movably guided in the cylinder () in the main load direction (r) of the elastomeric bearing. A buffer () is arranged on the bottom of the cylinder (), with at least one throttle channel () which is connected for flow-conduction with the work chamber (&#x2032;) of the elastomeric bearing extending through the side wall.
