Patent number: 11685435Abstract: A damper unit for use in a vibration-reducing assembly for a steering wheel is disclosed. The damper unit includes a slider configured, upon horn activation, to slide on a guide shaft. A damper element made from an elastomeric material is arranged on a first part of the slider. A molded horn spring element is molded directly on a second part of the slider and is configured to exert a spring force on the slider. The damper unit provides a unitary structure providing both a vibration damping function and a horn spring function in one single assembly unit, reducing the number of components to assemble. A vibration-reducing damper assembly including one or more such damper units is also disclosed, as well as a method of making such a damper unit.Type: GrantFiled: December 14, 2018Date of Patent: June 27, 2023Assignee: VIBRACOUSTIC FORSHEDA ABInventor: Erik Myklebust

Publication number: 20230174153Abstract: A frequency-tuned vibration damper assembly includes a horn plate connected to a vibrating surface of a steering wheel structure at a first interface via a plurality of first elastic damper elements so as to be movable in relation to the vibrating surface. A mass supported by the plate is movable in relation to the plate on an opposite front side of the plate. Elastic buffer elements are provided at a second interface between the plate and the mass. The stiffness of the elastic buffer elements is selected such that they form second elastic damper elements which together with the first elastic damper elements and the mass form a frequency-tuned dampened mass-spring system having two damping interfaces and being frequency-tuned to vibrations of said vibrating surface.Type: ApplicationFiled: April 21, 2021Publication date: June 8, 2023Applicant: Vibracoustic Forsheda ABInventors: Robin JOHANSSON, Kjell HILLBLOM

Publication number: 20220154794Abstract: A frequency-tuned vibration damper device and assembly which may be used in steering wheels for motor vehicles is provided. Elastomeric stiffening bridges or connectors, integrally formed in elastomeric damper bodies, are used to obtain different damping frequencies in different spatial directions (y, z). Stiffening in specific direction(s) (y) allows larger frequency differences to be achieved. Asymmetric elastomeric damper bodies are arranged to operate with a combination of compression-mode damping and shear-mode damping along a first axis (y), and dominantly with a shear-mode damping along a different, second direction (z).Type: ApplicationFiled: March 12, 2020Publication date: May 19, 2022Applicant: Vibracoustic Forsheda ABInventors: Robin JOHANSSON, Marcus JOHANSSON

Patent number: 11193552Abstract: A frequency tuned damper including at least one elastic element, and a method for the assembly of such a damper are disclosed. The damper comprises a deflection limiting mechanism arranged to prevent excessive movements of the elastic element if the damper is subjected to large external transient forces. The at least one elastic element forms part of the deflection limiting mechanism.Type: GrantFiled: October 9, 2018Date of Patent: December 7, 2021Assignee: VIBRACOUSTIC FORSHEDA ABInventor: Bengt-Göran Gustavsson

Patent number: 10006514Abstract: The present disclosure relates to a frequency tuned damper having a vibration body (19) and at least one elastic element (11, 13, 15, 17) which connects the vibration body to a surface (21), the vibrations of which is to be dampened. The elastic element has a wide portion (29) and a narrow portion (31) disposed at different locations on an axis (39) which is substantially parallel with the normal of the surface. The wider portion has a cavity (41), and the wide and narrow portions are inter-connected by a transition portion (43). The part of the narrow portion that is closest to the transition portion fits inside the cavity, as seen in the direction of the axis, such that the narrow portion can be pushed at least partly into the cavity, thereby flexing the transition portion.Type: GrantFiled: July 8, 2016Date of Patent: June 26, 2018Assignee: VIBRACOUSTIC FORSHEDA ABInventor: Bengt-Göran Gustavsson
