Patent number: 11390757Abstract: An electrically conductive component, which can be used in motor vehicles, may include a surface having a layered covering. The layered covering may be a melted and cured product of coating with a powder composition. Further, the layered covering may have a layer thickness of greater than 150 ?m, and the layered covering may be a single-layer covering. The layered covering may also include a pore-like layer structure. The pore-like layer structure of the layered covering may be responsible for an at-least-15% reduction in density of the layered covering relative to a density of the layered covering without the pore-like layer structure.Type: GrantFiled: October 14, 2016Date of Patent: July 19, 2022Assignees: THYSSENKRUPP FEDERN UND STABILISATOREN GMBH, THYSSENKRUPP AGInventors: Dieter Lechner, Pashalis Simos, Kerstin Hymon, Marcel Gross

Patent number: 11214112Abstract: A stabilizer adhesive bearing for a vehicle stabilizer may comprise an annular sleeve having a resilient inner contour for coaxial arrangement on the vehicle stabilizer. The resilient inner contour of the annular sleeve may comprise on a side facing the vehicle stabilizer a three-dimensionally structured surface with an adhesive receiving volume. The three-dimensionally structured surface has a maximum roughness depth (Rmax) greater than 45 ?m and a core roughness depth (RK) of at least 65% relative to the maximum roughness depth (Rmax) of the three-dimensionally structured surface. The maximum roughness depth (Rmax) is a total of the reduced tip height (Rpk), the core roughness depth (RK), and the reduced groove depth (Rvk). Further, the reduced tip height (Rpk), the reduced groove depth (Rvk), and the core roughness depth (RK) may be determined in accordance with EN ISO 13565-2: December 1997.Type: GrantFiled: June 13, 2018Date of Patent: January 4, 2022Assignees: THYSSENKRUPP FEDERN UND STABILISATOREN GMBH, THYSSENKRUPP AGInventors: Daniel Schuessler, Dieter Lechner, Frank Schneider, Angel Chong, Valeri Becker, Artur Kerbs, Joerg Ditzel

Patent number: 11007840Abstract: A bearing element for receiving a stabilizer on a vehicle may include a first elastomer body and a second elastomer body that are of half-shell-shaped design and that are arranged on one another so as to form a receiving passage. The receiving passage may receive a stabilizer rod of the stabilizer. The first and second elastomer bodies can be pressed onto and cohesively attached to the stabilizer rod of the stabilizer such that the stabilizer rod extends through the receiving passage. Further, the inner contour of the receiving passage may be configured so as to deviate from a circular contour.Type: GrantFiled: November 20, 2015Date of Patent: May 18, 2021Assignees: ThyssenKrupp Federo und Stabilisatoren GmbH, thyssenkrupp AGInventors: Dieter Lechner, Sebastian Bernard

Patent number: 10689726Abstract: A process for producing a spring or torsion bar from a steel wire by hot forming may involve providing a steel wire; thermomechanically forming the steel wire; cooling the steel wire thermomechanically; cutting the steel wire to length to give rods; heating the rods; hot forming the rods; and tempering the rods to give a spring or torsion bar, comprising quenching the rods to give a spring or torsion bar to a first cooling temperature, reheating the spring or torsion bar to a first annealing temperature, and cooling the spring or rod to a second cooling temperature. Further, in some examples, the cooling of the steel wire may be cooled to a temperature below a minimum recrystallization temperature such that at least a partly ferritic-pearlitic structure is established in the steel wire.Type: GrantFiled: July 15, 2015Date of Patent: June 23, 2020Assignees: THYSSENKRUPP FEDERN UND STABILISATOREN GMBH, THYSSENKRUPP AGInventors: Dieter Lechner, Marcel Groß, Heinz-Georg Gabor, Marco Roland, Dieter Brier

Patent number: 10099527Abstract: A suspension spring unit for a vehicle chassis can be positioned between a vehicle body and a wheel carrier. In some examples, the suspension spring unit may comprise at least four fiber composite leaf springs. The leaf springs may have a flat extent between two spring ends and may be connected to each other in pairs at a distance from each other. End connecting elements disposed over the spring ends may receive the spring ends so as to form at least two leaf spring pairs arranged in series. The leaf spring pairs may be connected to each other by central connecting elements via central regions between the spring ends of the leaf springs.Type: GrantFiled: February 19, 2015Date of Patent: October 16, 2018Assignee: THYSSENKRUPP FEDERN UND STABILISATOREN GMBHInventors: Dieter Lechner, Marcel Gross, Gerhard Scharr
