Abstract

A vibration and structure-borne noise insulating device on the floor (1) of a passenger carrying vehicle, particularly of a rail vehicle, should have a simple design, be effective, and be provided in a form that enables it to be efficiently mounted. To this end, a device of this type is characterized by the following features: the underside of the floor (1) is at least partially covered by insulating bodies (3); the insulating bodies (3) are joined to the floor via O-shaped spring clamps (2); the spring clamps (2) are oriented, with their upright O-axes, parallel to the vertical axis of the vehicle; the attachment to the floor (1) of the vehicle and to the insulating bodies (3) is effected at the ends of the spring clamps (2) located opposite one another in the direction of the upright O-axis. The insulating bodies (3) are located at a distance from the floor (1) that, even in the event of maximum possible vibration amplitudes of the insulating bodies (3), still reliably eliminates their effects on the floor (1).

Description

Schwingungs- und körperschallisolierende Einrichtung an dem Vibration and structure-borne soundproofing device on the
Boden eines FahrzeugesFloor of a vehicle
Die Erfindung betrifft eine schwingungs- und körperschallisolierende Einrichtung an dem Boden eines Personen befördernden Fahrzeuges, insbesondere Schienenfahrzeuges.The invention relates to a device that isolates vibrations and structure-borne noise on the floor of a vehicle carrying a person, in particular a rail vehicle.
Eine solche Einrichtung mit einfachen und funktionell gut wirksamen Mitteln rationell anbringbar zu gestalten, ist das der Erfindung zugrunde liegende Problem, das durch eine Einrichtung mit den kennzeichnenden Merkmalen des Patentanspruchs gelöst wird.To make such a device rationally attachable with simple and functionally effective means is the problem underlying the invention, which is solved by a device with the characterizing features of the patent claim.
Die erfindungsgemäßen Ω-förmigen Filterbügel können insbesondere aus Federstahl bestehen. Ω-förmig bedeutet eine Form', bei der die Schenkel eines U's Z-förmig ausgebildet sind. Durch eine solche Z-Form ist eine Elastizität in Richtung der aufrechten Achse eines Federbügels gegeben.The Ω-shaped filter bracket according to the invention can in particular consist of spring steel. Ω-shaped means a shape 'in which the legs of a U are Z-shaped. Such a Z shape provides elasticity in the direction of the upright axis of a spring clip.
Eine erfindungsgemäße schwingungs- und körperschallisolierende Einrichtung an dem Unterboden eines insbesondere Schienenfahrzeuges wirkt mit Bezug auf die Oberseite des Fahrzeugbodens in einem überraschend guten Maße dämpfend. Die über die Filterbügel an der Unterseite des Bodens anzubringenden Isolationskörper können aus verschiedenartigsten Materialien sein und insbesondere als mit einem Isolationsmaterial gefüllte Metallkassetten sein. Dabei können die Me- tallkassetten allseits geschlossen oder auch an ihrer jeweils dem Boden zugewandten Seite offen sein.A vibration and structure-borne noise isolating device according to the invention on the underbody of a rail vehicle in particular has a surprisingly good damping effect with respect to the top of the vehicle floor. The insulation bodies to be attached to the underside of the base via the filter bracket can be made from a wide variety of materials and in particular can be in the form of metal cassettes filled with an insulation material. The metal cassettes can be closed on all sides or can also be open on their side facing the floor.
Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An embodiment is shown in the drawing.
In dieser zeigt die einzigeIn this shows the only one
Fig. 1 eine Ansicht auf den Boden eines Schienenfahrzeuges in einem Ausschnitt.Fig. 1 is a view of the floor of a rail vehicle in a section.
An der Unterseite eines Bodens 1 eines Schienenfahrzeuges sind über Ω-förmig gestaltete Federbügel 2 aus Federstahl Isolationskörper 3 mit Abstand angebracht. Die Federbügel 2 sind mit dem Boden 1 sowie den Isolationskörpern 3 jeweils verschraubt .On the underside of a floor 1 of a rail vehicle, insulation bodies 3 are attached at a distance via Ω-shaped spring clips 2 made of spring steel. The spring clips 2 are screwed to the base 1 and the insulation bodies 3, respectively.
Die Isolationskörper 3 können mit einem Isolationsmaterial gefüllte Metallkassetten sein.The insulation bodies 3 can be metal cassettes filled with an insulation material.
Die Federbügel 2 können zwischen den Isolationskörpern 3 derart in Ausnehmungen dieser Isolationskörper 3 angebracht sein, dass die Isolationskörper 3 im wesentlichen lückenlos die Unterseite des Bodens 1 abdecken. The spring clips 2 can be fitted between the insulation bodies 3 in recesses in these insulation bodies 3 in such a way that the insulation bodies 3 essentially cover the underside of the base 1 without gaps.
