Publication number: 20230286342Abstract: A spring assembly for a vehicle chassis may include a spring that features a coating, a spring support, and an intermediate layer. The intermediate layer can be arranged between the spring and the spring support. The intermediate layer may be at least materially connected to the spring, in particular to the coating on a side facing the spring. The intermediate layer lies entirely or partially against the spring support on a side facing away from the spring and is connected to the spring support by a connection other than a material connection.Type: ApplicationFiled: April 26, 2021Publication date: September 14, 2023Applicants: ThyssenKrupp Federn und Stabilisatoren GmbH, thyssenkrupp AGInventors: Karsten WESTERHOFF, Jan-Yves SCHRAGE, Marcel GROSS

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: 11338845Abstract: A method for operating an electrical power steering system of a transportation vehicle wherein a steering wheel angle is pre-defined by a steering wheel as a measure for a desired wheel steering angle for at least one steerable wheel of the transportation vehicle, where an electrical power drive with an electric motor provides a steering support, and where a support torque of the steering support is reduced based on a damping function in response to the combustion engine of the transportation vehicle being started. Also disclosed is an associated electrical power steering system, to a computer program, and to a control appliance.Type: GrantFiled: August 17, 2017Date of Patent: May 24, 2022Inventors: Jens Zientek, Marcel Gross

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: 10675935Abstract: A suspension spring unit can be positioned between a vehicle body and a wheel support. The suspension spring unit may form a constituent part of the vehicle chassis, configured with spring bodies made from a fiber composite material. At least two ring bodies arranged in series may be made from a fiber composite material and may have a respectively closed contour. The two ring bodies may be connected to one another via at least one connecting element.Type: GrantFiled: February 19, 2015Date of Patent: June 9, 2020Assignee: THYSSENKRUPP FEDERN UND STABILISATOREN GMBHInventors: Marcel Gross, Dieter Lechner, Gerhard Scharr

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

Publication number: 20170283904Abstract: A process for producing a spring and/or torsion bar from a steel wire by cold forming may involve providing a steel wire; thermomechanically forming the steel wire above a minimum recrystallization temperature of the steel wire; cooling the steel wire; tempering the steel wire, which may involve heating, quenching, reheating, and cooling the steel wire; cold forming the steel wire at a cold forming temperature, the cold forming temperature being a temperature below the minimum recrystallization temperature of the steel wire; and separating the steel wire. With respect to the cooling of the steel wire, the steel wire may be cooled to a temperature below the minimum recrystallization temperature such that at least a partly ferritic-pearlitic structure is formed in the steel wire.Type: ApplicationFiled: July 15, 2015Publication date: October 5, 2017Applicants: ThyssenKrupp Federn und Stabilisatoren GmbH, ThyssenKrupp AGInventors: Dieter Lechner, Marcel Groß, Heinz Georg Gabor, Marco Roland
