Description
Zwillingsscheibenwischeranlage mit Seilantrieb Die Erfindung betrifft eine Zwillingsscheibenwischeranlage mit Seilantrieb, bei der erfindungsgemäß eine Umlenkrolle für das Seil auf der Antriebswelle für den einen Wischer lose angeordnet ist. Ein besonderes Lager für die Umlenkrolle, wie es bei bekannten Zwillingsscheibenwischeranlagen mit Seilzug vorgesehen ist, ist dann nicht erforderlich.Twin windshield wiper system with cable drive The invention relates to a twin windshield wiper system with cable drive, in which, according to the invention, a Deflection pulley for the rope on the drive shaft for one wiper is loosely arranged is. A special bearing for the pulley, as is the case with known twin windshield wiper systems is provided with a cable is then not necessary.
Die Erfindung ist an Hand der Zeichnung erläutert, in der ein Ausführungsbeispiel in Fig. 1 in Draufsicht, in Fig. 2 im Querschnitt, gesehen in Richtung auf den kurzen Schenkel der Platine, und in Fig. 3 im Querschnitt, gesehen in Richtung auf den langen Schenkel der Platine, dargestellt ist.The invention is explained with reference to the drawing, in which an exemplary embodiment in Fig. 1 in plan view, in Fig. 2 in cross section, seen in the direction of the short Legs of the board, and in Fig. 3 in cross section, viewed in the direction of the long leg of the board is shown.
Mit 1 ist eine L-förmige Grundplatte bezeichnet, auf der die Welle 2 für den einen Wischarm und die Welle 3 für den anderen Wischarm gelagert ist. Mit 4 ist der Antriebsmotor bezeichnet, der am freien Ende des kurzen Schenkels der Platte 1 befestigt ist und eine zweiarmige Kurbel 5 rotierend antreibt. An den beiden freien Enden der Kurbel 5 sind über Ösen 6 und 7 die freien Enden des Antriebsseiles 8 eingehängt, das um eine Schnurlaufrolle 9, die auf die Achse 2 aufgesteckt ist, gelegt ist. An der Kniestelle ist das Seil einerseits um eine fest auf die Welle 3 gesteckte Schnurlaufrolle 10 zum Antrieb der Welle 3 und andererseits um eine lose auf der gleichen Welle 3 gelagerte Umlenkrolle 11 gelegt. Zur Aufnahme der Zugkraft des Seiles ist die Welle 3 zweifach, einerseits in der Platte 11 und andererseits am gegenüberliegenden Ende, in einem Lagerbügel 12 gelagert.1 with an L-shaped base plate is referred to on which the shaft 2 is mounted for one wiper arm and the shaft 3 for the other wiper arm. 4 with the drive motor is referred to, which is at the free end of the short leg the plate 1 is attached and a two-armed crank 5 drives in rotation. To the Both free ends of the crank 5 are the free ends of the drive cable via eyelets 6 and 7 8 hooked around a cord roller 9, which is attached to the axis 2, is laid. At the knee, the rope is on the one hand around a tight on the shaft 3 inserted cord roller 10 for driving the shaft 3 and on the other hand to a Deflection roller 11 loosely mounted on the same shaft 3 is laid. To accommodate the The tensile force of the rope is twofold on the shaft 3, on the one hand in the plate 11 and on the other hand at the opposite end, stored in a bearing bracket 12.
Zum Ausgleich einer Längung des Seiles, die sich nie ganz vermeiden läßt, sind zwei Zugfedern 13 und 14 vorgesehen, die zwischen je zwei Stellen des Seiles befestigt sind und das Bestreben haben, das zwischen den Befestigungen gelegene Seilstück zusammenzuziehen und damit das Antriebsseil zu kürzen.To compensate for an elongation of the rope, which never completely avoid each other lets, two tension springs 13 and 14 are provided, each between two points of the Rope are attached and strive to be located between the attachments Pull together the piece of rope and thus shorten the drive rope.
Durch die Rotation der Kurbelwelle werden das Seil 8 und damit die Schnurlaufrollen 9 und 10 in oszillierende Bewegung versetzt die über die Wellen 2 und 3 auf die der Übersicht halber nicht dargestellten Wischarme, die auf die Wellen 2 und 3 aufgesteckt sind, übertragen wird.Due to the rotation of the crankshaft, the rope 8 and thus the Line rollers 9 and 10 set in an oscillating motion over the shafts 2 and 3 on the wiper arms, not shown for the sake of clarity, on the Shafts 2 and 3 are attached, is transferred.
Die Ansprüche 3 bis 5 haben keine selbständige Bedeutung.Claims 3 to 5 have no independent meaning.
