Patent number: 7635117Abstract: A bush bearing with a radial stiffness that changes in the circumferential direction. The bearing has at least one radial web with a high radial stiffness in a first radial major load-bearing direction, and at least one pocket with a significantly smaller radial stiffness than in the region of the radial web in a second radial direction which is preferably perpendicular to the first radial direction. To achieve a large force-displacement ratio and simultaneously a soft torsion characteristic, the inner element of the bearing of the invention is formed in two parts. It consists of a metal inner sleeve and a preferably also metal bearing core received in the inner sleeve. An elastomer or a rubber contour is vulcanized on the inner surface of the inner sleeve or the outer surface of the bearing core. The inner core is oversized with respect to the inner diameter of the elastomer contour. The bearing core is pressed into the inner sleeve, but does not adhere to it.Type: GrantFiled: January 24, 2006Date of Patent: December 22, 2009Assignee: ZF Friedrichshafen AGInventors: Karl Heuer, Karl-Walter Palluck, Wolfgang Schnaars, Andreas Vossel

Patent number: 7052004Abstract: A hydraulically damping rubber mount is provided with a variable channel length. The mount channel length can be adapted to the later intended use with a simple design during the manufacture without changing the design. The hydraulic mount has an elastomeric damping member, at least two chambers to accommodate a fluid damping agent and a channel carrier with a channel connecting the chambers in a flow-conducting manner. The channel has passage openings to the chambers. An incompletely closed ring, one end of which forms a channel deflection, is displaceably guided in the channel in the manner according to the present invention. The channel is divided as a result into two channel parts, which unite between the ends of the ring and through which the damping agent flows in opposite directions.Type: GrantFiled: October 29, 2002Date of Patent: May 30, 2006Assignee: ZF Lemförder MetallwarenInventors: Hubert Siemer, Claudia Willert, Frank Duisen, Andreas Vossel
