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

Patent number: 9702423Abstract: Device for damping vibrations of a vibration surface (21) of the frequency tuned resonance damping kind consisting of one or several elastic damping elements (1-4) and a vibration body (5) supported by the damping elements which together are tuned to damp the vibrations of said surface within a selected frequency range. First mutually co-operating form grip organs give a form grip between said damping elements (1-4) and the vibration surface (21), and second mutually co-operating form grip organs give a form grip between the damping elements and the vibration body. The form grip organs in addition have a recess with gripping surfaces (25-30, 33-35) for transferring vibrations.Type: GrantFiled: June 10, 2016Date of Patent: July 11, 2017Assignee: TRELLEBORG AUTOMOTIVE FORSHEDA ABInventor: Bengt-Göran Gustavsson

Patent number: 9689454Abstract: The present disclosure relates to a frequency tuned damper with an elastic element (7) adapted to connect a vibration body (5) to a surface (3). The elastic element has a wide portion (17) and a narrow portion (19) disposed at different locations along a longitudinal axis (23) which is substantially parallel with the normal of the surface when the damper is mounted, and has a first circumferential mounting groove (11) in the wide portion (17), for attaching the wide portion to the surface, and a second circumferential mounting groove (15) in the narrow portion (19), for attaching the narrow portion to the vibration body. The first circumferential mounting groove extends along an elongated path. This provides a damper that is capable of providing two different resonance frequencies in two perpendicular directions in the plane of the surface, and can easily be aligned in a desired direction.Type: GrantFiled: May 6, 2013Date of Patent: June 27, 2017Assignee: TRELLEBORG AUTOMOTIVE FORSHEDA ABInventor: Bengt-Göran Gustavsson

Patent number: 8950736Abstract: The present disclosure relates to a frequency tuned damper having a vibration body in the form of a casing. The casing has first and second parts which partly enclose a connector part which extends through a connector opening in the casing, such that it can be attached to a surface, the vibrations of which is to be dampened. The casing and the connector part are interconnected by means of a resilient member in the casing interior. The first casing part is a can portion 31 and the second casing part is a lid portion 33. The can portion defines an internal space having a mounting opening at one end to receive the resilient member, and the lid portion is arranged to be attached to the can portion over the mounting opening in order to compress the resilient member into a compressed state in the internal space. The internal space substantially fully contains the resilient member in the compressed state. The lid portion may be produced as e.g.Type: GrantFiled: March 19, 2009Date of Patent: February 10, 2015Assignee: Trelleborg Automotive Forsheda ABInventor: Bengt-Göran Gustavsson
