In der
Offenbarung der ErfindungDisclosure of the invention
Es ist Aufgabe der Erfindung, einen verbesserten Scheibenwischerantrieb zur Verfügung zu stellen.It is an object of the invention to provide an improved windshield wiper drive.
Die Aufgabe wird durch einen Scheibenwischerantrieb gemäß Anspruch 1 gelöst. Bevorzugte Ausführungsformen sind in den abhängigen Ansprüchen angegeben.The object is achieved by a windshield wiper drive according to claim 1. Preferred embodiments are given in the dependent claims.
Erfindungsgemäß wurde erkannt, dass ein Scheibenwischerantrieb dadurch besonders kostengünstig herstellbar ist, dass ein Elektromotor, der den Scheibenwischer antreibt und mittels eines Getriebes mit der Abtriebswelle für einen Scheibenwischerarm gekoppelt ist, als Linearmotor ausgebildet ist. Der Linearmotor weist dabei eine Antriebsstange auf, die mit dem Getriebe verbunden ist.According to the invention, it has been recognized that a windshield wiper drive can be produced particularly inexpensively by designing an electric motor which drives the windshield wiper and is coupled to the output shaft for a windscreen wiper arm by means of a transmission as a linear motor. The linear motor has a drive rod, which is connected to the transmission.
Auf diese Weise wird gewährleistet, dass das Getriebe des Scheibenwischerantriebs einfach und kompakt ausgebildet ist, sodass der Bauraumbedarf des Scheibenwischerantriebs besonders gering ist und ein exaktes Verfahren des Scheibenwischerarms ermöglicht wird.In this way, it is ensured that the transmission of the windshield wiper drive is simple and compact, so that the space requirement of the windshield wiper drive is particularly low and an exact process of the wiper arm is made possible.
In einer Ausführungsform der Erfindung ist das Getriebe mittels eines Bolzens mit der Antriebsstange verbunden, wobei der Bolzen in einem Langloch eines Hebels des Getriebes beweglich geführt ist und der Hebel drehfest mit der Abtriebswelle verbunden ist. Dies hat den Vorteil, dass das Getriebe nur wenige Komponenten aufweist und somit kostengünstig herstellbar ist.In one embodiment of the invention, the transmission is connected by means of a bolt to the drive rod, wherein the bolt is movably guided in a slot of a lever of the transmission and the lever is non-rotatably connected to the output shaft. This has the advantage that the transmission has only a few components and thus is inexpensive to produce.
In einer Ausführungsform der Erfindung weist das Getriebe an der Antriebsstange eine Zahnstange und die Abtriebswelle eine Verzahnung auf, in die die Zahnstange der Antriebsstange eingreift und damit eine translatorische Verschiebung der Antriebsstange in eine Rotation umwandelt. Dies hat den Vorteil, dass der Linearmotor entsprechend dem Bauraumbedarf in einem Kraftfahrzeug so um die Abtriebswelle angeordnet sein kann, dass er im Kraftfahrzeug bauraumgünstig verbaut werden kann.In one embodiment of the invention, the gear on the drive rod a rack and the output shaft has a toothing, in which engages the rack of the drive rod and thus converts a translational displacement of the drive rod in a rotation. This has the advantage that the linear motor can be arranged according to the space requirement in a motor vehicle around the output shaft, that it can be installed space-saving in the motor vehicle.
In einer Ausführungsform der Erfindung ist an einer zur Zahnstange gegenüberliegenden Seite der Antriebsstange eine Führungsrolle angeordnet, um ein seitliches Ausweichen der Antriebsstange zu vermeiden. Auf diese Weise wird sichergestellt, dass die Antriebsstange auch bei hoher Last, beispielsweise bei einem Blockieren eines Wischerarms, nicht von der Verzahnung der Abtriebswelle abrutscht.In one embodiment of the invention, a guide roller is arranged on a side of the drive rod opposite the toothed rack in order to avoid lateral deflection of the drive rod. In this way, it is ensured that the drive rod does not slip off the toothing of the output shaft even under high load, for example when a wiper arm is blocked.
In einer Ausführungsform der Erfindung ist das Getriebe als Hebelgetriebe ausgebildet, das wenigstens zwei miteinander verbundene Gelenkhebel aufweist, wobei ein erster Gelenkhebel mit der Abtriebswelle drehfest verbunden ist. Ein zweiter Gelenkhebel ist mittels des Bolzens mit der Antriebsstange verbunden. Dies hat den Vorteil, dass die translatorische Bewegung spielfrei an der Abtriebswelle in eine Rotation umgewandelt werden kann.In one embodiment of the invention, the transmission is designed as a lever mechanism which has at least two interconnected articulated levers, wherein a first articulated lever is rotatably connected to the output shaft. A second articulated lever is connected by means of the bolt with the drive rod. This has the advantage that the translational movement can be converted without play on the output shaft into a rotation.
In einer Ausführungsform steht der zweite Gelenkhebel des Hebelgetriebes in einer Parkposition des Scheibenwischerarms orthogonal zur Antriebsstange. Auf diese Weise wird in der Parkposition eine Selbsthemmung des Scheibenwischerantriebs gewährleistet.In one embodiment, the second articulated lever of the lever mechanism is in a parking position of the wiper arm orthogonal to the drive rod. In this way, a self-locking of the windshield wiper drive is ensured in the parking position.
In einer Ausführungsform ist der Elektromotor mit einem Steuergerät, das eine Positionsbestimmungseinrichtung aufweist, verbunden. Dabei umfasst die Positionsbestimmungseinrichtung einen Sensor, um die Winkelposition der Abtriebswelle zu ermitteln. Dies hat den Vorteil, dass dem Steuergerät eine Information über die Position des Scheibenwischerarms zur Verfügung gestellt werden kann.In one embodiment, the electric motor is connected to a control unit which has a position-determining device. In this case, the position-determining device comprises a sensor to determine the angular position of the output shaft. This has the advantage that information about the position of the windscreen wiper arm can be made available to the control unit.
