Description

Windschutzscheibenreiniger für Kraftfahrzeuge Die Erfindung bezieht .sich auf einen Windschutzscheibenreiniger für Kraftfahrzeuge, der ,durch einen Elektromotor kurzer Baulänge angetrieben wird. Bei bekannten Scheibenreinigern dieser Art besitzt der Anker seitliche Bohrungen, in die ein Teil der Ankerlagerung .eingreift. Der Luftspalt muß bei diesen Motoren gering sein. Schon wenig Spiel in der doppelseitigen Ankerlagerung macht .dieses unmöglich, da der Anker einseitig an die Polschuhe gezogen wird und sich infolgedessen nicht mehr drehen kann. Die Vergrößerung des Luftspaltes bedingt aber größere Amperewindungszahl und.damit erhöhte Baulänge. Der .ganze Windschutzscheibenreini.ger soll aber geringes Gewicht haben.Automotive windshield cleaners The invention relates to .self to a windshield cleaner for motor vehicles that, through a Electric motor of short length is driven. With known window cleaners this Art, the anchor has lateral holes in which a part of the anchor bearing engages. The air gap must be small in these motors. Little game in the double-sided Armature bearing makes this impossible, as the armature is pulled on one side of the pole pieces and as a result can no longer rotate. The enlargement of the air gap but requires a larger number of ampere turns and thus increased overall length. The whole windshield cleaner but should have a low weight.

Gemäß .der Erfindung wird eine gute Lagerung dadurch erzielt, daß der Anker des Elektromotors auf einer hohlen, im Gehäuse des Windschutzscheibenreinigers fest gelagerten Achse drehbar gelagert ist. Letztere dient gleichzeitig einem Antriebsritzel .des Wischergetriebes, welches :durch eine Kupplung mit dem Anker verbunden ist, zur Lagerung. Die hohle Welle sticht ganz unter den Anker; gegenüber der bekannten Ausführung ist bei gleicher Baulänge eine längere Lagerung erzielt. Da das Lagerlängsmittel nahezu mit .dem Mittel des Ankers zusammenfällt, kann selbst bei vergleichsweise größerer Lagerluft der Anker nur unwesentlich seitlich abweichen. Demnach kann :der Luftspalt klein gewählt werden, die Amperewindungszahl wird gering, und der Elektromotor erhält kürzere Baulänge.According to the invention, good storage is achieved in that the armature of the electric motor on a hollow, in the housing of the windshield cleaner fixed axis is rotatably mounted. The latter also serves as a drive pinion . of the wiper gear, which: is connected to the armature by a coupling, for storage. The hollow shaft sticks right under the anchor; compared to the known Execution, longer storage is achieved with the same overall length. Because the bearing longitudinal center almost coincides with the means of the anchor, even with comparatively larger bearing clearance of the armature only slightly deviate laterally. Accordingly: the Air gap can be chosen to be small, the number of ampere turns is low, and the electric motor gets shorter overall length.

Eine beispielsweise Ausführung der Erfindung ist in .der Zeichnung in der Abbildung dargestellt.An example embodiment of the invention is in. The drawing shown in the picture.

Auf der Hülse i ist der aus Kollektor-,hülse :2 und Ankerblechen 3 sowie Wicklung 4 gebildete Anker .gelagert. In einem Lagerschild 5 sitzt .die Hülse i fest oder lösbar. Letztere dient gleichzeitig einer Antriebsachse 6, die .durch die Kupplung 7 mit der Kollektorhülse 2 und somit auch, mit dem Anker gekuppelt ist, als Lagerung.On the sleeve i is that of the collector, sleeve: 2 and anchor plates 3 and winding 4 formed armature .gellager. In a bearing plate 5 sits .the sleeve i fixed or detachable. The latter also serves a drive axle 6, which. Durch the coupling 7 is coupled to the collector sleeve 2 and thus also to the armature is, as storage.
