Description

Elektromotor, insbesondere zum Antriebe von Windschutzscheibenwischern an Kraftfahrzeugen. Die Erfindung betrifft einen Antriebsmotor für Windschutzscheibenwischer und bezieht sich insbesondere auf die Lagerung der Motorwelle.Electric motors, in particular for driving windshield wipers on motor vehicles. The invention relates to a drive motor for windshield wipers and relates in particular to the mounting of the motor shaft.

Bei solchen Motoren muß einerseits auf eine gedrängte Bauart gesehen werden, anderseits werden, wie im gesamten Kraftwagenbau, auch an die selbsttätigen Scheibenwischer hohe Anforderungen in bezug auf die Geräuschlosigkeit des Antriebs gestellt, so daß die Lagerung eine sehr sorgfältige sein muß.With such engines, on the one hand, a compact design must be considered on the other hand, as in the entire automotive industry, also to the automatic ones Windshield wipers have high requirements with regard to the noiselessness of the drive so that the storage must be very careful.

Gemäß der Erfindung werden zu diesem Zweck die Lagernaben für die Motorwelle in entsprechenden Bohrungen des Ankers unter dem Kollektor und unter den Ankerwicklungen bis nahe an die äußersten Ankerbleche geführt. Damit ist eine einfache Lagerung von reichlicher Lagerlänge geschaffen.According to the invention, the bearing hubs for the Motor shaft in corresponding holes in the armature under the collector and under the armature windings up close to the outermost armature plates. So that's a easy storage of ample storage length created.

In der Zeichnung ist ein Achsialschnitt durch das Motorgehäuse dargestellt.The drawing shows an axial section through the motor housing.

In dem Motorgehäuse 6, 7, 8 ist der Anker gelagert, der aus den Ankerblechen i und den Wicklungen 2 und 3 besteht. In diesen Anker ist eine Büchse q. eingesetzt, die in ihrem mittleren, unter den Ankerblechen i liegenden Teil mit der Welle 5 fest verbunden ist. Die letztere ruht in den seitlichen Abschlußdeckeln 6, 7, die auf die Stirnflächen des Gehäuses aufgesetzt sind. Der Abschlußdeckel 6 trägt eine vorspringende Lagernabe 9, die sich unter der entsprechend abgesetzten Büchse q: und unter dem Kollektor io bzw. der Ankerwicklung z bis nahe an das äußerste Ankerblech dieser Seite erstreckt. In die Nabe 9 ist eine Laufbüchse i i eingesetzt. Auf der anderen Seite ist die Welle 5 in gleicher Weise von einer vorspringenden Nabe 12, des Abschlußdeckels7 umschlossen, die ebenfalls innerhalb der Ankerwicklung 3 bis nahe an das äußerste Ankerblech dieser Wellenseite reicht. Auch in die Lagernabe 12 ist eine Laufbüchse 13 eingesetzt. Die Welle 5 ist auf der Kollektorseite mit einer Verzahnung 1q. versehen, mittels welcher sie das Übersetzungsgetriebe für den Scheibenwischer antreibt.The armature, which consists of the armature plates i and the windings 2 and 3, is mounted in the motor housing 6, 7, 8. In this anchor is a sleeve q. used, which is firmly connected to the shaft 5 in its middle part located under the armature plates i. The latter rests in the side cover plates 6, 7, which are placed on the end faces of the housing. The cover 6 carries a projecting bearing hub 9 which extends under the correspondingly offset sleeve q: and under the collector io or the armature winding z to close to the outermost armature plate on this side. In the hub 9 a liner ii is used. On the other hand, the shaft 5 is enclosed in the same way by a projecting hub 12, the end cover 7, which also extends within the armature winding 3 to close to the outermost armature plate of this shaft side. Also in the bearing hub 12, a bushing 1 3 is used. The shaft 5 is on the collector side with a toothing 1q. provided, by means of which it drives the transmission gear for the windshield wiper.
