Patent number: 9868330Abstract: A leaf spring assembly for a wheel suspension of a motor vehicle comprises a leaf spring of fibre-reinforced plastics for resiliently supporting a wheel carrier of the motor vehicle. The leaf spring comprises a first end portion, a spring portion, a bendable portion and a second end portion. The leaf spring further comprises a first receiving device for supporting the first end portion and a second receiving device for supporting a second end portion. The first receiving device and the second receiving device are designed such that the first end portion and the second end portion are held in a non-displaceable way relative to one another. At least one of the first and second receiving devices are designed such that the respective associated end portion is supported in a moment-free way in the receiving device.Type: GrantFiled: July 23, 2014Date of Patent: January 16, 2018Assignee: Muhr und Bender KGInventors: Christoph Hahn, Rainer Forster, Vladimir Kobelev, David Muller, Lutz Manke

Patent number: 7896359Abstract: The invention relates to a method of producing a divided tube stabilizer having a swivel motor (2) mutually coupling two tube stabilizer halves (3, 4), a first tube stabilizer half (3) being non-rotatably connected with a first connection part (5) of the swivel motor, and a second stabilizer half (4) being non-rotatably connected with a second connection part (6) of the swivel motor (2). In order to achieve that the tube stabilizer halves can be easily linked in a non-rotatable manner with the connection parts of the swivel motor, the following process steps are suggested: a. The tube ends to be connected with the connection parts (5, 6) of the swivel motor (2) are expanded and upset in one working step by means of a mandrel (20); b. the tube stabilizer halves (3, 4) with the expanded and upset ends are shaped to their final shape by bending; c. the finished bent tube stabilizer halves (3, 4) are subjected to a heat treatment; d.Type: GrantFiled: November 4, 2005Date of Patent: March 1, 2011Assignee: ThyssenKrupp Technologies AGInventors: Hans Dziemballa, Lutz Manke, Frank Schneider

Patent number: 7828918Abstract: The invention relates to a method for the thermomechanical treatment of steel. According to said method, the parent material is heated to a temperature in excess of the re-crystallization temperature, the structure is austenitized, held at an equalized temperature and then formed and subsequently quenched to form martensite and tempered. Round steel bars, whose re-crystallization temperature is adjusted over the bar length in a compensation furnace, constitute the parent material. The round steel bars are subsequently re-modeled by cross-rolling, remaining substantially straight and after the critical deformation degree has been exceeded are subjected to dynamic re-crystallization processes. The round steel bars are then subjected to a post-heating process above the Ac3 temperature, in order to undergo a complete static re-crystallization and finally are quenched from the austenitic state to form martensite and tempered.Type: GrantFiled: March 5, 2004Date of Patent: November 9, 2010Assignee: ThyssenKrupp Automotive AGInventors: Hans Vondracek, Hans DziemBalla, Lutz Manke, Alexander Borowikow, Reinhard Uhrich, Matthias Hüttner

Publication number: 20090056400Abstract: The invention relates to a method and a device for transversely rolling stepped hollow shafts or cylindrical hollow parts from a pipe. The invention achieves the object of rolling stepped hollow shafts of the most varied dimensions and also of greater lengths in a flexible manner from a pipe using a small number of simple tools. In accordance with the invention, the object is achieved by virtue of the fact that rolling tools which can be radially advanced and are disposed in a planet-like manner around the workpiece are used to roll the contour of the transition from a central diameter in one portion of the workpiece to the central diameter in the adjacent portion by means of co-ordinated control of the radial advance of the rolling tools and the axial feed of the workpiece, and a mandrel head having an outer diameter which is adapted to the smallest inner diameter of the two portions is disposed underneath the rolling tools.Type: ApplicationFiled: August 29, 2008Publication date: March 5, 2009Applicant: ThyssenKrupp Bilstein Suspension GmbHInventors: Hans Dziemballa, Lutz Manke, Mario Houska, Thomas Ficker, Andre Hardtmann

Publication number: 20070074792Abstract: The invention relates to a method for producing helical springs or stabilisers consisting of steel. According to said method, the parent material is heated to a temperature in excess of the re-crystallisation temperature, the structure is austenitised, held at an equalised temperature and then formed and subsequently quenched to form martensite and tempered. Round steel bars, whose re-crystallisation temperature is adjusted over the bar length in a compensation furnace, constitute the parent material. The round steel bars are subsequently re-modelled by cross-rolling, remaining substantially straight and after the critical deformation degree has been exceeded are subjected to dynamic re-crystallisation processes. The round steel bars are then subjected to a post-heating process above the Ac3 temperature, in order to undergo a complete static re-crystallisation, are wound to form a helical spring or bent to form a stabiliser and are finally quenched from the austenitic state to form martensite and tempered.Type: ApplicationFiled: May 3, 2004Publication date: April 5, 2007Inventors: Hans Vondracek, Hans Dziemballa, Lutz Manke, Alexander Borowikow
