Description
Scheibenwischer für Kraftfahrzeuge Die Erfindung betrifft einen Scheibenwischer für Kraftfahrzeuge mit einem pendelnd angetriebenen Wischerarm.Windshield wipers for motor vehicles The invention relates to a windshield wiper for motor vehicles with a pendulum driven wiper arm.
Bei bekannten Scheibenwischern dieser Art wird die Wischerwelle von einem Elektromotor über einen Schubstangentrieb pendelnd angetrieben. Bei modernen Scheibenwischern ist die Wischfrequenz so hoch und der Anpreßdruck der Wischblätter an die Scheibe so kräftig, daß Triebteile nach längerer Betriebszeit ausschlagen, so daß der Wischwinkel sich unzulässig vergrößert und die Wischblätter gegen den Rand der Windschutzscheibe schlagen und dabei beschädigt werden.In known windshield wipers of this type, the wiper shaft is from driven to oscillate by an electric motor via a push rod drive. With modern With windshield wipers, the wiping frequency is so high and so is the contact pressure of the wiper blades on the disc so hard that the drive parts knock out after a long period of operation, so that the wiping angle increases impermissibly and the wiper blades against the Hit the edge of the windshield and be damaged in the process.
Es ist bekannt, für die Wischwelle eine Begrenzung des Pendelwinkels durch Anschläge vorzusehen. Die Erfindung stellt eine Verbesserung dieser Begrenzungseinrichtung dar, indem die Wischerwelle an ihrem antriebsseitigen Ende einen abgewinkelten Fortsatz erhält, der mit Anschlägen zusammenwirkt, die am Wellengehäuse vorgesehen sind.. Von besonderem Vorteil ist es, die Anschläge zur Pufferung aus weichem Material auszubilden und sie zur Justierang der Bregrenzung in ihrer Lage verstellbar anzubringen.It is known to limit the pendulum angle for the wiper shaft to be provided by stops. The invention provides an improvement on this restriction device by the wiper shaft having an angled extension at its drive-side end receives, which cooperates with stops that are provided on the shaft housing .. It is particularly advantageous if the stops for buffering are made of soft material train and attach them adjustable in their position to Justierang the Brebegrenzung.
Die Erfindung ist an Hand der Zeichnung näher erläutert, in der in Abb. 1 ein Ausschnitt des Getriebes eines Scheibenwischers nach der Erfindung in Draufsicht und in Abb. 2 im Querschnitt dargestellt ist.The invention is explained in more detail with reference to the drawing, in which in Fig. 1 shows a section of the transmission of a windshield wiper according to the invention in Top view and is shown in Fig. 2 in cross section.
In der Zeichnung ist mit 1 die Wischerwelle bezeichnet, auf deren gerändeltes freies Ende der der Übersicht halber nicht dargestellte Wischarm aufgesteckt ist. Die Wischerwelle ist in einer Hülse 2 gelagert und trägt an ihrem hinteren Ende ein Kegelzahnrad 3, das mit einem Kegelzahnrad 4 an der Antriebswelle 5 im Eingriff steht. Die Antriebswelle 5 wird über einen nicht dargestellten Stangentrieb von einem ebenfalls nicht dargestellten Elektromotor angetrieben. Das freie Ende der Wischerwelle ist abgewinkelt. In der Bahn der Abwinklung 6 sind am Gehäuse zwei Anschläge 7 und 8 vorgesehen, die die Schwenkbewegungen der Wischerwelle begrenzen. Der Durchstoß der Wischerwelle durch das Getriebegehäuse 9 ist mit einer Dichtung 10 abgeschlossen. Die Anschläge 7 und 8 sind zur Pufferung aus weichem Material ausgebildet. Vorzugsweise kann dazu der unter dem Markennamen Vulkollan bekannte Kunststoff dienen.In the drawing, 1 denotes the wiper shaft, on whose knurled free end attached to the wiper arm, not shown for the sake of clarity is. The wiper shaft is mounted in a sleeve 2 and carries on its rear End of a bevel gear 3, which is connected to a bevel gear 4 on the drive shaft 5 in the Engagement is. The drive shaft 5 is via a rod drive, not shown driven by an electric motor, also not shown. The free end the wiper shaft is angled. In the path of the bend 6 there are two on the housing Stops 7 and 8 are provided which limit the pivoting movements of the wiper shaft. The penetration of the wiper shaft through the gear housing 9 is done with a seal 10 completed. The stops 7 and 8 are made of soft material for buffering educated. Preferably, the one known under the brand name Vulkollan can be used for this purpose Serving plastic.
Gemäß einer zweckmäßigen Weiterbildung des dargestellten Ausführungsbeispiels sind die Anschläge 7 und 8 in ihrer Lage beispielsweise durch Schrauben verstellbar, so daß die Begrenzung des Wischwinkels durch Verstellen der Anschläge justierbar ist.According to an expedient development of the illustrated embodiment the stops 7 and 8 are adjustable in their position, for example by screws, so that the limitation of the wiping angle can be adjusted by adjusting the stops is.
