Patent number: 10605323Abstract: 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.Type: GrantFiled: January 25, 2017Date of Patent: March 31, 2020Assignees: Ford-Werke GmbH, Boge Elastmetall GmbHInventors: Frank Wittbracht, Josef Burwinkel, Stefan Loheide, Achim Lordick, Thomas Schmitz, Marc Mendel

Patent number: 8100235Abstract: A controllable hydraulic bearing for damping vibrations in a defined frequency band is proposed, which includes an elastomeric body (1), two chambers which are filled with a magneto-rheological fluid and connected with one another by at least one channel (2), 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 (2). According to the invention, the magnetic field in the region of the channel (2) is an inhomogeneous magnetic field.Type: GrantFiled: August 8, 2008Date of Patent: January 24, 2012Assignee: ZF Friedrichshafen AGInventors: Stefan Loheide, Hubert Siemer, Burkhard Meyer, Josef Burwinkel

Patent number: 7392976Abstract: 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 (1) chambers (19, 20; 22, 23) of the chamber pairs (21, 24) can be connected via a closable chamber wall opening (40).Type: GrantFiled: December 9, 2004Date of Patent: July 1, 2008Assignees: ZF Friedrichshafen AG, Audi AGInventors: Hubert Siemer, Josef Burwinkel, Stefan Loheide, Burkhard Meyer

Publication number: 20070296131Abstract: An impact damper (7) with at least one damper unit (8, 9, 10, 11). The damper unit (8, 9, 10, 11) includes at least one elastomer spring element (15), at least one fluid-filled primary chamber (24), and at least one fluid-filled secondary chamber (27), as well as one nozzle opening (26) connecting the two chambers (24, 27), wherein the fluid can be displaced during spring deflection of the elastomer spring element (15) from the primary chamber (24) into the secondary chamber (27). The impact damper (7) includes a damper unit (8, 9, 10, 11) has the shape of a rotational toroidal or an annular body. The impact damper of the invention is suitable, in particular, for high-end damping applications, for example the wheel suspension of automobiles, and more particularly for overcoming such divergent requirements as an early force buildup, a uniform energy dissipation with a long stroke, and a high energy absorption.Type: ApplicationFiled: June 8, 2007Publication date: December 27, 2007Applicant: ZF FRIEDRICHSHAFEN AGInventors: Hubert SIEMER, Stefan LOHEIDE, Josef BURWINKEL
