Description

Scheibenwisch- und -waschgerät Gegenstand des Hauptpatents 1032115 ist ein Scheibenwisch- und -waschgerät, vorzugsweise für Kraftfahrzeuge, bei dem das Antriebsmittel des Scheibenwischers mit dem Antrieb einer hin- und hergehenden Wasserförderpumpe für den Scheibenwascher in Verbindung steht und die die kraftschlüssige Verbindung herstellende sowie den Pumpensaughub bewirkende Kraft durch einen Elektromagneten erzeugt wird, der den Pumpenkolben od. dgl. durch axiale Verschiebung gegen Kurvensteuermittel des Wischers führt, die den Druckhub bewirken.Windscreen wiper and washer device is the subject of main patent 1032115 is a windscreen wiper and washer device, preferably for motor vehicles, in which the drive means of the wiper with the drive of a reciprocating The water feed pump for the windshield washer is connected and the non-positive The force that establishes the connection and the pump suction stroke is effected by an electromagnet is generated, which od the pump piston. Like. By axial displacement against cam control means the wiper leads, which cause the pressure stroke.

In Fortführung dieses Gedankens ist nun gemäß der Erfindung vorgesehen, daß die Wasserförderpumpe für den Scheibenwascher mit ihren Antriebsmitteln in der Gesamtbaueinheit des Scheibenwischer-Motors untergebracht ist, wobei die Betätigungsstange der Wasserförderpumpe achsparallel oder nahezu achsparallel zur Ankerwelle des Scheibenwischer-Motors, die Wasserförderpumpe mit dem elektrischen Kuppelmagneten kollektorseitig und die Antriebsmittel für die Betätigung der Pumpe getriebeseitig angeordnet sind. Weiterhin ist erfindungsgemäß die die Verbindung zwischen der Pumpe und den Antriebsmitteln herstellende Kolbenstange der Wasserförderpumpe durch eine Bohrung im Feldmagneten, der vorzugsweise als Dauermagnet ausgebildet ist, hindurchgeführt. Gemäß der Erfindung ist ferner vorgesehen, die Kolbenstange der Wasserförderpumpe über einen Übertragungshebel und einen Stößel mit Rückholfeder mit den Kurvensteuerungsmitteln in kraftschlüssige Verbindung zu bringen.In continuation of this idea it is now provided according to the invention, that the water feed pump for the windshield washer with its drive means in the Entire structural unit of the windshield wiper motor is housed, the operating rod the water feed pump axially parallel or almost axially parallel to the armature shaft of the windshield wiper motor, the water pump with the electric coupling magnet on the collector side and the Drive means for actuating the pump are arranged on the transmission side. Farther is according to the invention the connection between the pump and the drive means producing the piston rod of the water pump through a hole in the field magnet, which is preferably designed as a permanent magnet, passed through. According to the invention it is also provided that the piston rod of the water feed pump via a transmission lever and a plunger with a return spring in frictional engagement with the cam control means To bring connection.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing shown.

Die Figur zeigt den Gesamtaufbau. Der Scheibenwischer-Motor besteht aus dem Feldmagneten 1 mit seinen Polschuhen 2, dem Anker 3, dem Kollektor 4 und den Bürsten 5. Die drehende Kraft des Elektromotors wird über ein Zahnrädergetriebe, bestehend aus Zahnrädern 6, 7, 8 und 9, auf die Abtriebswelle 10 übertragen. Die Zahnräder des Getriebes sind in einem Getriebegehäuse 11 gelagert. Die Wasserförderpumpe 12 mit einem elektrischen Kuppelmagneten 13 ist kollektorseitig oberhalb des Feldmagneten 1 angeordnet. Die Kolbenstange 14 der Wasserförderpumpe 12 wird durch eine Bohrung 15 im Feldmagneten 1 hindurchgeführt und steht getriebeseitig mit einem Kraftübertragungshebel 16 in kraftschlüssiger Verbindung. Der Kraftübertragungshebel 16 ist einerseits in einem Auflager 17 gelagert und andererseits an einem Stößel 18 geführt. Der Stößel 18 hat seine Führung im Getriebegehäuse 11 und steht im gekuppelten Zustand in kraftschlüssiger Verbindung mit einer Kurvenscheibe 19, die ihrerseits auf dem Zahnrad 9 befestigt ist. In ausgekuppeltem Zustand, d. h. bei stromlosem Kuppelmagneten 13, hebt eine Rückholfeder 20 den Stößel 18 von der Kurvenscheibe 19 ab und führt die Wasserförderpumpe 12 über den Kraftübertragungshebel 16 und die Kolbenstange 14 in ihre Ausgangsstellung zurück.The figure shows the overall structure. The wiper motor exists from the field magnet 1 with its pole pieces 2, the armature 3, the collector 4 and the brushes 5. The rotating power of the electric motor is transmitted via a gear train, consisting of gears 6, 7, 8 and 9, transferred to the output shaft 10. the The gear wheels of the transmission are mounted in a transmission housing 11. The water feed pump 12 with an electric coupling magnet 13 is on the collector side above the field magnet 1 arranged. The piston rod 14 of the water feed pump 12 is through a bore 15 passed through the field magnet 1 and is on the transmission side with a power transmission lever 16 in a frictional connection. The power transmission lever 16 is on the one hand stored in a support 17 and, on the other hand, guided on a plunger 18. The plunger 18 has its guidance in the gear housing 11 and is in a non-positive manner in the coupled state Connection to a cam disk 19, which in turn is fastened to the gear wheel 9 is. In the disengaged state, i. H. when the coupling magnet 13 is de-energized, one lifts Return spring 20 removes the plunger 18 from the cam disk 19 and guides the water feed pump 12 via the power transmission lever 16 and the piston rod 14 in its starting position return.
