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 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.

Controllable hydraulic bearing

A hydraulically damping bush bearing () has an inner part () with a hole () extending along a longitudinal axis (); an outer sleeve () surrounding the inner part (); an elastomeric damping member () arranged between the inner part () and the outer sleeve (); and at least two chamber pairs () with at least two separate chambers () each, which are filled with a hydraulic fluid. The two chambers () of a first chamber pair () are arranged axially along the longitudinal axis () and the two chambers () of a second chamber pair () are arranged radially in relation to the longitudinal axis () and are arranged in the axial direction of the longitudinal axis () between the two chambers () of the first chamber pair (); a channel carrier (), which connects to one another the two chambers () each of one of the chamber pairs () via at least one damping channel () each arranged in or at the channel carrier (); and an outer bush (), which surrounds the elastomeric damping member (), the outer sleeve (), the channel carrier () as well as the at least two chamber pairs (). The chambers () of the first chamber pair () and the chambers () of the second chamber pair () overlap in some areas at least an axial partial section (A, B) in relation to the longitudinal axis ().

Hydraulically damping bush bearing

A hydraulically damping bush bearing is provided with hydraulic area formed from at least two chamber pairs, wherein each chamber pair is formed from at least two separate chambers, which are connected to one another via at least one damping channel. The hydraulically damping bearing with damping in both the axial direction and the radial direction is further improved to the effect that damping or stiffness that can be switched off or on depending on the operating state is also made possible. The hydraulically damping bush bearing () chambers () of the chamber pairs () can be connected via a closable chamber wall opening ().
