Abstract
Description
Die Erfindung bezieht sich auf eine gummielastische Dichtung, insbesondere für Türen, Hauben oder Klappen von Kraftfahrzeugen, mit einer Anlagefläche, die ela stisch an einer Gegenfläche anliegt.The invention relates to a rubber-elastic seal, in particular for Doors, hoods or flaps of motor vehicles, with a contact surface, the ela abuts against a counter surface.
Eine bekannte derartige Dichtung (DE 30 16 263 A1) weist einen U-förmigen Ab schnitt des Profilquerschnittes auf, der aus einem steiferen Material besteht, wäh rend eine daran angeformte Dichtlippe aus einem weicheren bzw. elastischeren Material besteht, um etwaige größere Unterschiede im Dichtungsspalt sicher über brücken zu können.A known seal of this type (DE 30 16 263 A1) has a U-shaped shape cut the profile cross-section, which consists of a stiffer material, wäh rend a molded sealing lip made of a softer or more elastic Material is made to safely over any major differences in the seal gap to be able to bridge.
Es ist ferner bekannt (EP 0 172 144 B1), das Gleiten der Anlagefläche der Dichtung auf der zugeordneten Gegenfläche und die Gefahr des Abtragens von Lack dadurch zu unterbinden, daß der den Spalt überbrückende Querschnittsbereich der Dichtung aus Gummi besteht, der eventuell auftretende Relativbewegungen in sich aus gleicht.It is also known (EP 0 172 144 B1), the sliding of the contact surface of the seal on the assigned counter surface and the risk of removing paint to prevent that the cross-sectional area of the seal bridging the gap is made of rubber, the relative movements that may occur equal.
Kommt es aber zu Relativbewegungen zwischen der Anlagefläche einer Gummi- Profilleiste und der zugeordneten Gegenfläche, wie beispielsweise bei Kraftfahr zeugtüren, können störende Knarz-Geräusche entstehen. Sie ergeben sich durch den spontanen Übergang von der Haft- in die Gleitreibung. However, if there are relative movements between the contact surface of a rubber Profile bar and the associated counter surface, such as in motor vehicles doors, annoying creaking noises can occur. They result from the spontaneous transition from static to sliding friction.
Man kann dem zum Teil dadurch begegnen, daß man einen Gleitlack für die Dich tung verwendet oder die Anlagefläche mit einem Flock beschichtet. Auch bestimmte Strukturierungen der in Kontakt kommenden Oberflächen sind möglich. All dies stellt jedoch einen vergleichsweise großen Aufwand dar und befriedigt trotzdem nicht in vollem Umfang.You can counter this in part by having a lubricating varnish for you used or coated the contact surface with a flock. Certain too Structuring of the surfaces that come into contact is possible. All of this poses however represents a comparatively large effort and still does not satisfy in fully.
Der Erfindung liegt die Aufgabe zugrunde, mit relativ einfachen Mitteln die störenden Knarz-Geräusche zu vermeiden, oder doch zumindest deutlich zu reduzieren.The invention has for its object the disruptive with relatively simple means To avoid creaking noises, or at least to reduce them significantly.
Diese Aufgabe wird erfindungsgemäß durch die im Patentanspruch 1 umschriebe nen Merkmale gelöst.This object is described by the claim 1 Features resolved.
Durch die Verwendung eines hochdämpfenden Elastomers im Querschnittsbereich der Anlagefläche der Dichtung wird bei Relativbewegungen zwischen der Dichtung und der zugeordneten Gegenfläche, beispielsweise dem Türausschnitt eines Kraft fahrzeugs, die Geschwindigkeit des Übergangs von der Haft- in die Gleitreibung gesenkt und damit die Geräuschentstehung. Das gezielt hochdämpfend ausgelegte Material hat ein hohes Verhältnis zwischen Verlustarbeit und gespeicherter Arbeit bei einem Verformungsvorgang.By using a highly damping elastomer in the cross-sectional area The contact surface of the seal is used for relative movements between the seal and the associated counter surface, for example the door section of a force vehicle, the speed of the transition from static to sliding friction lowered and thus the generation of noise. The specifically designed high damping Material has a high relationship between lost work and saved work during a deformation process.
Zum Erreichen des gewünschten Effektes kann die Anlagefläche der Dichtung mit einer hochdämpfenden Beschichtung versehen sein und die hochdämpfende Schicht kann durch Koextrusion aufgebracht werden. Es ist aber auch möglich, das gesamte Dichtungsprofil aus einem hochdämpfenden Material herzustellen.To achieve the desired effect, the contact surface of the seal can be used be provided with a highly damping coating and the highly damping Layer can be applied by coextrusion. But it is also possible that to produce the entire sealing profile from a highly damping material.
Werden nur Teilbereiche des Profilquerschnitts mit dem hochdämpfenden Material ausgeführt, kann dieses Material durchaus auch dieselbe Härte wie das Grundmate rial des restlichen Profilquerschnittes haben. Es ist weiterhin auch möglich, die Be schichtung härter zu wählen oder auch weicher zu wählen. Die Härte oder Weichheit hat nicht unbedingt direkten Einfluß auf die Dämpfung des Materials.Only parts of the profile cross-section with the high-damping material executed, this material can also have the same hardness as the base material rial of the remaining profile cross-section. It is also possible to use the Be to choose layering harder or to choose softer. The hardness or softness does not necessarily have a direct influence on the damping of the material.
