Abstract
Description
Die Erfindung bezieht sich auf einen Schwingungsdämpfer mit einem Behälterrohr, das einen radial nach außen hervorstehenden Rohrstutzen aufweist, mit dem ein Gehäuse verbunden ist, in dem eine elektrisch betätigbare Steuerventileinrichtung angeordnet ist. The invention relates to a vibration damper with a container tube having a radially outwardly projecting pipe socket, with which a housing is connected, in which an electrically actuated control valve device is arranged.
Bei derartigen Schwingungsdämpfern kann es bei Off-road- oder Schlechtwegfahrten dazu kommen, daß Steine oder andere Gegenstände durch die Räder hochgeschleudert werden und gegen das Gehäuse der Steuerventileinrichtung oder dessen Anschlußkabel prallen und diese sowie die Steuerventileinrichtung beschädigen, wodurch die Funktion des Schwingungsdämpfers beeinträchtigt wird. Dies kann insbesondere überraschend zu gefährlichen Fahrsituationen führen. In such vibration dampers may occur during off-road or Schlechtewegfahrten that stones or other objects are thrown up by the wheels and bounce against the housing of the control valve device or its connecting cable and damage them and the control valve device, whereby the function of the vibration is impaired. This can, in particular, surprisingly lead to dangerous driving situations.
Aufgabe der Erfindung ist es daher einen Schwingungsdämpfer der eingangs genannten Art zu schaffen, der diese Nachteile vermeidet und gegen eine Beschädigung dieser Art zumindest weitgehend geschützt ist. The object of the invention is therefore to provide a vibration damper of the type mentioned, which avoids these disadvantages and is at least largely protected against damage of this kind.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Gehäuse der Steuerventileinrichtung von einer Schutzkappe umschlossen ist. This object is achieved in that the housing of the control valve device is enclosed by a protective cap.
Durch diese Ausbildung kann es zwar möglicherweise zu Beschädigungen der Schutzkappe kommen. Beschädigungen des Gehäuses sowie der darin angeordneten Steuerventileinrichtung werden aber vermieden, so daß die einwandfreie Funktion des Schwingungsdämpfers nicht durch Steinschläge beeinträchtigt wird. Through this training, it may possibly come to damage the cap. Damage to the housing and the control valve means arranged therein are avoided, so that the proper function of the vibration damper is not affected by rockfalls.
Das gleiche trifft auch zu, wenn die Steuerventileinrichtung ein nach außen geführtes Anschlußkabel aufweist, das von einem flexiblen Schutzschlauch oder von einem Schutzrohr umschlossen ist. The same also applies if the control valve device has an outwardly led connecting cable, which is enclosed by a flexible protective tube or by a protective tube.
Schutzkappe und/oder Schutzschlauch oder Schutzrohr können aus einem elastischen Werkstoff, insbesondere aus einem Kunststoff bestehen. Protective cap and / or protective tube or protective tube may consist of an elastic material, in particular of a plastic.
Auf besondere Befestigungsmittel zur Befestigung der Schutzkappe am Gehäuse und/oder des Schutzschlauches oder des Schutzrohres am Anschlußkabel kann verzichtet werden, wenn die Schutzkappe das Gehäuse und/oder der Schutzschlauch oder das Schutzrohr das Anschlußkabel formschlüssig umschließt. On special fasteners for attaching the cap on the housing and / or the protective tube or the protective tube on the connecting cable can be omitted if the protective cap encloses the housing and / or the protective tube or the protective tube form-fitting the connecting cable.
Vorzugsweise ist dabei das Gehäuse von der Schutzkappe und/oder das Anschlußkabel von dem Schutzschlauch oder dem Schutzrohr unter mechanischer Vorspannung umschlossen. Preferably, the housing is enclosed by the protective cap and / or the connecting cable of the protective tube or the protective tube under mechanical bias.
Dabei können die Schutzkappe und/oder der Schutzschlauch oder das Schutzrohr einfach angebracht werden, wenn die Schutzkappe und/oder der Schutzschlauch oder das Schutzrohr aus einer Schrumpffolie bestehen. In this case, the protective cap and / or the protective tube or the protective tube can be easily attached if the protective cap and / or the protective tube or the protective tube consist of a shrink film.
Alternativ dazu mit den gleichen Vorteilen können die Schutzkappe und/oder der Schutzschlauch oder das Schutzrohr eine Kunststoffumspritzung des Gehäuses und/oder des Anschlußkabels sein. Alternatively, with the same advantages, the protective cap and / or the protective tube or the protective tube may be a plastic encapsulation of the housing and / or the connecting cable.
Zur Befestigung der Schutzkappe mit erhöhter Sicherheit kann auch die Schutzkappe ein das Behälterrohr unter Vorspannung radial umschließendes Halteband aufweisen. To attach the cap with increased security and the cap can have a container tube under bias radially enclosing strap.
Erstreckt sich die Schutzkappe von dem Gehäuse aus über den Verbindungsbereich von Rohrstutzen und Gehäuse, so bildet die Schutzkappe in Doppelfunktion auch einen Schutz gegen Eindringen von Feuchtigkeit in den Innenraum des Gehäuses. If the protective cap extends from the housing over the connecting region of pipe socket and housing, the protective cap in double function also forms a protection against penetration of moisture into the interior of the housing.
Umschließt dabei die Schutzkappe formschlüssig das Gehäuse, so ist anhand von Beschädigungsspuren an der Schutzkappe gleichzeitig eine Mißbrauchserkennung möglich, wenn das Gehäuse zur Manipulation der Steuerventileinrichtung geöffnet wurde. While the protective cap encloses the housing in a form-fitting manner, misuse detection is simultaneously possible based on traces of damage to the protective cap when the housing has been opened to manipulate the control valve device.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die einzige Figur der Zeichnung zeigt einen Längsschnitt eines Schwingungsdämpfers. An embodiment of the invention is illustrated in the drawing and will be described in more detail below. The sole figure of the drawing shows a longitudinal section of a vibration damper.
