Abstract
Description
Anhängerzugvorrichtung für Kraftfahrzeuge, umfassend einen mit dem Kraftfahrzeug verbundenen Zughaken und ein an einem Ende des Zughakens angebrachtes Kupplungskopfstück für die Verbindung mit einem entsprechenden Gegenstück an einem Anhänger. Weiterhin betrifft die vorliegende Erfindung ein dämpfendes Element für eine derartige Anhängervorrichtung.towing equipment for motor vehicles, comprising a towing hook connected to the motor vehicle and a to a End of the towing hook mounted coupler head piece for connection to a corresponding counterpart on a trailer. Furthermore, the present invention relates to a damping Element for Such a trailer device.

Patentanmeldung
Ausgehend von dem zuvor genannten Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, eine Anhängerzugvorrichtung der zuvor genannten Art bereitzustellen, welche den bei dem Anhängerbetrieb entstehenden Geräuschpegel vermindert. Weiterhin soll ein dämpfendes Element für eine derartige Anhängerzugvorrichtung zur Verfügung gestellt werden.outgoing from the aforementioned prior art, the object of the present invention in a towing device of the above to provide said type, which in the trailer operation reduced noise level. Furthermore, a damping Element for Such trailer hitch device to disposal be put.
Erfindungsgemäß wird dieses Problem hinsichtlich der Anhängerzugvorrichtung durch eine Anhängerzugvorrichtung der eingangs beschriebenen Art, mit den kennzeichnenden Merkmalen des Anspruchs 1, sowie hinsichtlich des dämpfenden Elementes durch ein dämpfendes Element mit den kennzeichnenden Merkmalen des Anspruchs 7 gelöst. Die in den Unteransprüchen genannten Merkmale betreffen bevorzugte Weiterbildungen der erfindungsgemäßen Aufgabenlösung.According to the invention this Problem with trailer hitch by a trailer hitch of the type described above, with the characterizing features of claim 1, as well as with respect to the damping element by a steaming Element solved with the characterizing features of claim 7. In the the dependent claims mentioned features relate to preferred developments of the task solution according to the invention.
Dadurch, dass am Zughaken der Anhängerzugvorrichtung zwischen dem Kupplungskopfstück und dem Kraftfahrzeug ein dämpfendes Element angeordnet ist, werden die hörbaren Geräusche bei einem Anhängerbetrieb im Fahrzeuginneren minimiert.Thereby, that on the towing hook of the trailer towing device between the coupling head piece and the motor vehicle a damping Element is arranged, the audible noise in a trailer operation minimized in the vehicle interior.
Es kann vorgesehen sein, dass das dämpfende Element den Zughaken umschließt, wodurch eine Körperschallunterbrechung erreicht wird.It can be provided that the damping Element encloses the tow hook, causing a structure-borne noise interruption is reached.
Es kann weiterhin vorgesehen sein, dass das dämpfende Element als Gummimetalllager ausgeführt ist, welches sowohl ein Innenteil und Außenteil als auch eine Platte umfassen kann. Vorteilhaft können das Innenteil, das Außenteil und die Platte aus einem starren, vorzugsweise metallischen Material bestehen. Des Weiteren kann vorgesehen sein, dass zwischen Außenteil und Innenteil ein Zwischenelement einbringbar ist, welches vorzugsweise aus einem weichen Gummi hergestellt und fest mit dem Außenteil und/oder dem Innteil verbindbar ist. Eine derartige Anordnung eines dämpfenden Elementes weißt eine Körperschall unterbrechende Funktion auf.It can also be provided that the damping element as a rubber-metal bearing accomplished which is both an inner part and outer part as well as a plate may include. Can be advantageous the inner part, the outer part and the plate made of a rigid, preferably metallic material. Furthermore, it can be provided that between the outer part and inner part an intermediate element can be introduced, which is preferably made of a soft rubber and stuck to the outer part and / or the Innteil is connectable. Such an arrangement of absorbing Elementes know a structure-borne sound interrupting function.
In einer vorteilhaften Weiterbildung der Erfindung kann das dämpfende Element aus jedem erdenklichen Körperschall dämpfenden Material sein. Durch die unmittelbare Verbindung des dämpfenden Elementes mit dem Zughaken wird die Schwingungsenergie umgewandelt, so dass kein Luftschall mehr erzeugt werden kann.In an advantageous embodiment of the invention, the damping Element of every conceivable structure-borne sound absorbing Be material. Due to the direct connection of the damping element with the towing hook, the vibration energy is converted, so that no more airborne sound can be generated.
Vorzugsweise wird das dämpfende Element direkt unterhalb des Kupplungskopfstückes an dem Zughaken angebracht. Möglich ist es jedoch, dass das dämpfende Element in einem beliebigen Bereich am Zughaken zwischen Kupplungskopfstück und Kraftfahrzeug anordnenbar ist, da die Position keinen Einfluss auf die Wirkung der Körperschallbrücke hat.Preferably becomes the steaming Element mounted directly below the coupling head piece on the towing hook. Possible It is, however, that the muffling Element in any area on the towing hook between coupling head piece and motor vehicle is arrangeable, since the position does not affect the effect the structure-borne sound bridge has.
