Patent number: 8100423Abstract: A connector piece for the articulated connection of structural elements of a chassis of a motor vehicle. The connector piece has a main body, formed from at least one metal sheet, which has at least one bearing or joint and includes a housing connected to the main body and an inner part which is fitted within an inside space of the housing and can move relative to the housing. The housing comprises a housing portion that surrounds the inside space and includes at least two sheet-metal strips that are arranged adjacent one another, in a longitudinal direction, and are bent between their ends, in opposite directions transverse to the longitudinal direction, such that the metal strips partially surround the inside space on different sides.Type: GrantFiled: March 6, 2008Date of Patent: January 24, 2012Assignee: ZF Friedrichshafen AGInventors: Jochen Kruse, Frank Budde, Frank Nachbar, Stefan Schönhoff

Publication number: 20110221153Abstract: A linking rod for a vehicle comprising a basic body (2). The basic body (2) comprises a bearing housing (3) and a joint housing (4) which are spaced apart from one another by a coupling piece (9) of the basic body (2). The bearing housing (3), of the basic body (2). is formed from a first plastic material which is surrounded by an enclosure (7) which is made from a second plastic material that is softer than the first plastic material.Type: ApplicationFiled: July 30, 2008Publication date: September 15, 2011Applicant: ZF FRIEDRICHSHAFEN AGInventors: Ulrich Bladt, Olaf Beutler, Günter Lohfink, Karl-Walter Palluck, Stefan Loheide, Dirk Lamla, Stefan Schönhoff, Christian Maassmann

Patent number: 7216860Abstract: A mount support of a force connection strut is provided manufactured from plastic/metal composite materials for a chassis of a motor vehicle. The force connection strut has an elongated basic body and a sleeve (H) passing through the basic body. The sleeve (H) has a flange (F) on at least one side and is connected to the basic body by extrusion coating with plastic at least at one of its ends.Type: GrantFiled: November 7, 2002Date of Patent: May 15, 2007Assignee: ZF Lemförder Metallwaren AGInventors: Frank Budde, Stefan Schönhoff, Jochen Kruse

Patent number: 7192214Abstract: A sealing bellows is provided having a jacket (1b) arranged between first and second edges (1a, 1c) of the sealing bellows. The edges (1a, 1c) of the sealing bellows are sealingly in contact with components in the assembled state of the sealing bellows (1). At least a first edge (1a) of the sealing bellows has radially inwardly pointing teeth (3a), which engage a contour of a component or a housing (2) of a ball and socket joint to form a snap connection.Type: GrantFiled: March 20, 2003Date of Patent: March 20, 2007Assignee: ZF Lemörder Metallwaren AGInventors: Stefan Schönhoff, Frank Budde

Patent number: 7159880Abstract: A connection strut of a chassis of a passenger car or utility vehicle for the connection between the chassis and the wheel carrier, preferably an axle strut or a chassis control arm, with an elongated basic body and at least two mount supports arranged at the end for introducing and leading out forces. The basic body has a composite between a flat metal insert and a plastic structure forming the rest of the contour. The plastic structure is formed by encasement of the metal insert. The rest of the contour is defined here as the difference between the final contour of the force connection strut and the portion that is formed by the metal insert.Type: GrantFiled: November 4, 2002Date of Patent: January 9, 2007Assignee: ZF Lemförder Metallwaren AGInventors: Frank Budde, Jochen Kruse, Stefan Schönhoff

Patent number: 7037022Abstract: A ball-and-socket joint, preferably for chassis suspensions and/or steering mechanisms of motor vehicles, is presented, which has a ball pivot pin (1), which is accommodated rotatably and tiltably in a joint housing (8) with one of its free ends with a spherical joint area (3). The other free end of the ball pivot pin (1) is fixed to a body part. The ball-and-socket joint has a stop device for limiting the tilting movement of the ball pivot pin (1) in the joint housing (8), which comprises a stop element, which is arranged in the bottom area (11) of the joint housing (8) rotationally symmetrically to the longitudinal axis of the sphere and cooperates with the end-side joint area (6) of the ball pivot pin (1).Type: GrantFiled: October 8, 2002Date of Patent: May 2, 2006Assignee: ZF Lemförder Metallwaren AGInventors: Stefan Schönhoff, Markus Fischer
