Description

Die Erfindung betrifft eine Wischeranlage insbesondere für die Außenscheiben von Kraftfahrzeugen. Aufgabe der Wischeranlage ist es, die Außenscheiben von Kraftfahrzeugen frei von Flüssigkeit und Schmutz zu halten, wobei die Geräusche des Wischens und des Umschlagens des Wischers mit Rücksicht auf die Passagiere möglichst klein sein sollten.The The invention relates to a wiper system, in particular for the outer panes of motor vehicles. Task of the wiper system is to free the outer panes of motor vehicles from Keep liquid and dirt, with the noise of wiping and turning the wiper with respect on the passengers should be as small as possible.

Die DE 24 10 130 A1 beschreibt einen Scheibenwischer mit mehreren Druckbereichen, der im Wesentlichen aus einer großen Brücke besteht, an deren beiden Enden jeweils ein Schwengel als kleine Brücke gelenkig gekuppelt ist wobei die Berührung zwischen jedem Schwengel und dem elastischen Blatt gemäß mehreren Druckbereichen stattfindet. Durch diese gelenkige Verteilung auf mehrere Schwengel und Brücken kommt eine gewisse Verteilung des Anpresskraft und Dämpfung zustande.The DE 24 10 130 A1 describes a windshield wiper with several pressure areas, which consists essentially of a large bridge, at both ends of which a pivot is articulated as a small bridge with the contact between each pivot and the elastic sheet takes place according to several pressure ranges. Through this articulated distribution on several wings and bridges, a certain distribution of the contact force and damping comes about.

Die DE 87 02 684 U1 zeigt eine Wischvorrichtung für Scheiben von Kraftfahrzeugen, mit einem lang gestreckten, einendig an einem Antriebselement befestigten Wischerarm, dessen anderes, freies Ende elastisch gegen die Scheibe vorgespannt und über ein Rad an dieser abgestützt ist und an dem Wischerarm ein an der Scheibe angelegtes, diese überstreichendes Wischelement gehalten ist wobei der Wischerarm und das Wischelement innerhalb einer auf der Scheibe stehenden Ebene mit Abstand voneinander angeordnet sind und dass diese beiden Bauelemente über wenigstens ein elastisches Zwischenstück miteinander verbunden sind, welches in Betriebsstellung der Wischvorrichtung vorgespannt ist. Dieses elastische Zwischenstück erzeugt eine Verteilung der Anpresskraft und Dämpfung.The DE 87 02 684 U1 shows a wiper device for windows of motor vehicles, with an elongated, one end fastened to a drive element wiper arm, the other, free end is resiliently biased against the disc and supported by a wheel on this and on the wiper arm an applied to the disc, this sweeping Wiper element is held, wherein the wiper arm and the wiper element are arranged within a standing on the disc plane with distance from each other and that these two components are connected to each other via at least one elastic intermediate piece, which is biased in the operating position of the wiper device. This elastic intermediate piece generates a distribution of the contact pressure and damping.

Weiterhin zeigt die DE 34 31 936 A1 eine Wischeranlage mit einem Wischerarm und einer mit einem Verstärkungsprofil verstärkten Wischleiste bei welches das Verstärkungsprofil mit dem Wischerarm durch eine Vielzahl von elastischen Blattfedern verbunden ist welche eine dämpfende Wirkung haben.Furthermore, the shows DE 34 31 936 A1 a wiper system with a wiper arm and a reinforced with a reinforcing profile wiper strip in which the reinforcing profile is connected to the wiper arm by a plurality of elastic leaf springs which have a damping effect.

Die vorliegende Erfindung beschäftigt sich mit dem Problem, die Wischgeräusche und Umlegegeräusche des Wischgummis zu minimieren und gleichzeitig eine hohe Wischqualität zu erzielen.The The present invention addresses the problem of the wiping noises and turning noises of the wiper blade rubber to minimize and at the same time a high wiping quality to achieve.

Die Erfindung beruht auf dem allgemeinen Gedanken, dass durch die Gestaltung übereinander liegender, mit Koppelelementen verbundener, Federschienen sowohl eine homogene Verteilung der Anpresskraft vom Wischarm zur Wischerlippe wie auch eine bessere Dämpfung des Gesamtsystems erreicht werden kann. Die obere Federschiene ist an den angetriebenen Wischerarm mittig angebunden. Die untere Federschiene trägt das Wischergummi, welches über die Glasoberfläche der Scheibe streicht.The Invention is based on the general idea that by superimposing the design, connected with coupling elements, spring rails both a homogeneous Distribution of the contact force from the wiper arm to the wiper lip as well as a better damping of the overall system can be achieved. The upper spring rail is centered on the driven wiper arm tethered. The lower spring rail carries the wiper rubber, which sweeps over the glass surface of the disk.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Günstige Ausgestaltungen und Vorteile der Erfindung sind der Beschreibung sowie den weiteren Ansprüchen 2 bis 4 zu entnehmen.These The object is achieved by the features of claim 1. Cheap designs and advantages of the invention are the description as well as the other Claims 2 to 4 refer.

In einem bevorzugten Ausführungsbeispiel sind die Koppelelemente zwischen einer oberen Federschiene, an welcher ein Wischerarm angebunden ist und einer zweiten, von der oberen Federschiene beabstandeten unteren Federschiene, an welcher ein Wischgummi angebunden ist, angeordnet. Dabei sind die Koppelelemente so ausgestaltet, dass sie einzeln so parametrierbar sind, dass sie den Anforderungen hinsichtlich der Verteilung der Anpresskraft der Wischlippe sowie der Dämpfung genügen.In In a preferred embodiment, the coupling elements between an upper spring rail, to which a wiper arm is connected and a second, spaced from the upper spring rail bottom Spring rail on which a squeegee is connected, arranged. The coupling elements are designed so that they individually are parameterizable so that they meet the requirements the distribution of the contact pressure of the wiper lip and the damping suffice.

In einer weiteren Ausführungsform ist die Parametrierbarkeit der Koppelelemente durch verschiedene Härtegrade dargestellt. So können die Koppelelemente von der Mitte der Wischeranlage hin zu den beiden Enden zunehmend weicher oder härter werden.In Another embodiment is the parameterizability the coupling elements represented by different degrees of hardness. Thus, the coupling elements of the center of the wiper system become increasingly softer or harder towards the two ends.

In einer anderen Ausführungsform ist die Parametrierbarkeit der Koppelelemente durch verschiedene Dämpfungsgrade dargestellt. So können die Koppelelemente von der Mitte der Wischeranlage hin zu den beiden Enden zunehmend höhere oder niedrigere mechanische Dämpfungsgrade aufweisen.In In another embodiment, the parameterability is the coupling elements represented by different degrees of damping. Thus, the coupling elements of the center of the wiper system towards the two ends progressively higher or lower have mechanical damping levels.

Eine Ausführungsform variiert die Parametrierbarkeit der Koppelelemente durch verschiedene Abstände zwischen den Koppelelementen auf den Federschienen zueinander. So können die Abstände der Koppelelemente von der Mitte der Wischeranlage hin zu den beiden Enden zunehmend größer oder kleiner werden.A Embodiment varies the parameterability of the coupling elements by different distances between the coupling elements on the spring rails to each other. So the distances of the Coupling elements from the middle of the wiper system to the two Ends become progressively larger or smaller.
