Patent number: 10434834Abstract: A method for operating a motor vehicle with a chassis arrangement having at least two vibration dampers. A body control is carried out at least partially with the vibration dampers. The chassis arrangement further has at least one stabilizer. During transverse accelerations below a threshold acceleration the stabilizer contributes to the body control less than the vibration dampers and contributes more than the vibration dampers from the threshold acceleration upward.Type: GrantFiled: November 18, 2015Date of Patent: October 8, 2019Assignee: ZF Friedrichshafen AGInventors: Norbert Ackermann, Helmut Baalmann, Andreas Förster, Sven Greger, Steffen Heyn, Holger Kirchner, Sven Philip Krüger, Thomas Manger, Hendrik Marquar, Christian Maurischat, Stefan Rappelt, Alexander Schwarz, Jens Seiler, Achim Thomae, Michael Triebel

Publication number: 20170008558Abstract: An arrangement for connecting chassis parts, in particular a screw connection, between a structure made of a fiber-plastic composite and a metallic load-introducing element, designed as a traction member. The structure is double-walled having a first wall and at least a second wall spaced from the first wall. The first and second walls have each coaxially positioned recesses and a spacer, having a through hole, is positioned between the first and second walls. The load-introducing element extends through at least one recess and the hole of the spacer. The load-introducing element has a holding part assigned to it, and the load-introducing element and the holding part are connected to one another by a connecting segment. The connecting segment and/or the holding part essentially pass through the first and/or the second wall.Type: ApplicationFiled: January 12, 2015Publication date: January 12, 2017Inventors: Sven Philip KRÜGER, Andreas VÄTH, Hendrik MARQUAR, Josef RENN, Sven GREGER, Edmont HOFMANN

Patent number: 8910759Abstract: A vibration damper including a cylinder with a cylinder-side connection member. The at least one mounted component is fastened to the cylinder by a material bond. The cylinder and the mounted component are made of plastic. The mounted component and/or the cylinder are based on at least one ready-prepared semi-finished product that forms the surface of the vibration damper on at least one body side in the final state. Plastic supplemental volume fractions determine the finished body contour.Type: GrantFiled: September 9, 2010Date of Patent: December 16, 2014Assignees: ZF Friedrichshafen AG, Leichtbau-Zentrum Sachsen GmbHInventors: Hendrik Marquar, Manfred Schuler, Josef Renn, Klaus Stretz, Karin Sundermann, Michael Zutzmann, Werner Hufenbach, Martin Lepper, Jens Werner, Enrico Ladusch, Stefan Effmert

Patent number: 8297600Abstract: A plastic spring having a corrugated tubular body with connection surfaces at its ends for transmitting force between two structural component parts which are movable relative to one another. A connection surface of the plastic spring is constructed as a tubular body which engages in a cup element of one of the supporting structural component parts. The cup element can be filled with a displacement mass, and the tubular body accordingly carries out a displacing movement within the cup element for axially adjusting the preloading of the plastic spring.Type: GrantFiled: September 9, 2010Date of Patent: October 30, 2012Assignees: ZF Friedrichshafen AG, Leichtbau-Zentrum Sachsen GmbHInventors: Hendrik Marquar, Manfred Schuler, Josef Renn, Klaus Stretz, Karin Sundermann, Michael Zutzmann, Werner Hufenbach, Martin Lepper, Jens Werner, Christian Köhler

Publication number: 20110215209Abstract: A supporting tube for a vibration damper including an axial supporting surface on which rests an outer cylinder of the vibration damper. A fixing cap which holds a second axial supporting surface for securing the cylinder against loading in the opposing direction. The fixing cap is connected to the supporting tube by positive engagement, and separate locking elements for both parts are arranged between the fixing cap and the supporting tube, which locking elements position the outer cylinder relative to the supporting tube.Type: ApplicationFiled: September 9, 2010Publication date: September 8, 2011Applicant: ZF Friedrichshafen AGInventors: Hendrik Marquar, Manfred Schuler, Josef Renn, Klaus Stretz, Karin Sundermann, Michael Zutzmann
