Publication number: 20200124088Abstract: A bearing bush includes a core, an intermediate sleeve surrounding the core in a manner extending in a circumferential direction, an outer sleeve surrounding the intermediate sleeve in a manner extending in the circumferential direction, an elastomer body disposed between the intermediate sleeve and the outer sleeve, and a stop device. In embodiments, at axial ends of the core, the stop device protrudes from the core in a radial direction and limits a movement of the intermediate sleeve in an axial direction. The intermediate sleeve is mounted on the core and, relative to the stop device, in a circumferentially rotatable manner. The outer sleeve has several projections. The intermediate sleeve has at least one counter-projection which overlaps in the radial direction with the projections for limiting the axial deflection of the outer sleeve relative to the core.Type: ApplicationFiled: May 18, 2018Publication date: April 23, 2020Inventors: Bartolomeo Firszt, Oliver Helmcke, Ulrich Fuhrmans, Michael Mess, Rodscha Drabon, Peter Koczar, Dirk Rochell, Lars Sievers

Patent number: 9744823Abstract: A rear axle arrangement for a motor vehicle is disclosed having two independent wheel suspension systems with in each case at least two links and a wheel support. The links producing a connection between the vehicle body and the wheel support and being coupled at their ends in a relatively movable manner via elastic bearings. In the case of static wheel loading, the wheels of the rear axle exhibiting toe-in, which rear axle arrangement is distinguished by at least one elastic bearing of a link having a frequency-dependent bearing stiffness in such a way that, in the case of driving straight ahead and high-frequency dynamic wheel loading, a change into toe-out takes place on account of an increasing bearing stiffness of the bearing and the wheel is pressed into negative camber as a result of the change into toe-out.Type: GrantFiled: September 14, 2015Date of Patent: August 29, 2017Assignee: Benteler Automobiltechnik GmbHInventors: Rodscha Drabon, Peter Koczar

Publication number: 20120068429Abstract: In a method of making a stabilizer, a rubber molding is vulcanized onto an inner side of an outer shell to produce a rubber bearing. After coating a stabilizer bar, the rubber bearing is vulcanized onto the stabilizer bar in a joining zone while maintaining the rubber bearing under a defined tension using a biasing tool. After vulcanization and removal of the biasing tool, a bearing bracket is connected in surrounding relationship to the rubber bearing while maintaining the rubber bearing under a defined tension.Type: ApplicationFiled: June 6, 2011Publication date: March 22, 2012Applicant: Benteler Automobiltechnik GmbHInventors: WULF HÄRTEL, Ullrich Hammelmaier, Peter Koczar

Patent number: 6363613Abstract: The method for manufacturing a torsion bar shoulder bearing has four method steps: (1) the manufacture of a elastomeric spring as a not fully vulcanized molding for receiving a sleeve-shaped or bolt-shaped inner connecting part in a central bore and an outer sleeve-shaped connecting element; (2) the pretreatment of the surface regions, to be connected to the molding, of the connecting parts by means of an adhesive system; (3) the pushing of the molding onto the inner connecting part and the insertion of the molding thus reinforced into the outer connecting part (or in the opposite sequence), as a result of which the elastomeric molding is clamped under moderate prestress between the two connecting parts, and (4) the concluding full vulcanization of the elastomeric molding in the assembled bearing, using a tempering furnace, at temperatures of below 140 to 150° C.Type: GrantFiled: April 28, 2000Date of Patent: April 2, 2002Assignee: WOCO Franz-Josef Wolf & Co.Inventors: Franz Josef Wolf, Uwe Schleinitz, Peter Koczar
