Description
Die Erfindung hat den Zweck, jederzeit und ohne Zerlegung von Motor oder Getriebe die Endlage der Abtriebsachse von mit Endschaltern versehenen motorischen Antrieben ein- oder nachstellen zu können. Sie ist insbesondere für elektrische Scheibenwischer vorteilhaft, bei denen durch einen sogenannten Parkschalter, der zu dem eigentlichen Betätigungsschalter parallel geschaltet ist, die Stromzufuhr dann unterbrochen wird, wenn die Wischerarme in der gewünschten Endlage sich befinden. Solche Wischer sind bekannt, und die richtige Einstellung der Endlage muß bei diesen entweder durch Verdrehen der auf der Wischerachse lösbar befestigten Antriebskurbel oder aber durch sorgfältige Montage vorgenommen werden, wenn Achse und Kurbel vernietet sind. Beide Verfahren lassen nur selten eine nachträgliche Korrektur der Endlage zu, da die Wischermotoren meist verdeckt oder schwer zugänglich eingebaut sind.The invention has the purpose at any time and without dismantling the engine or gear the end position of the output axis of motorized ones provided with limit switches To be able to adjust or readjust drives. It is especially for electrical Windshield wipers advantageous where by a so-called parking switch, the is connected in parallel to the actual operating switch, the power supply is then interrupted when the wiper arms are in the desired end position. Such wipers are known, and the correct setting of the end position must be with these either by turning the drive crank, which is releasably attached to the wiper shaft or by careful assembly if the axle and crank are riveted are. Both methods rarely allow a subsequent correction of the end position too, since the wiper motors are usually installed concealed or difficult to access.
Die Anordnung nach vorliegender Erfindung ermöglicht diese Einstellung an der eingebauten Anlage, ihr Aufbau und ihre Wirkungsweise gehen aus den Fig. i und 2 hervor.The arrangement of the present invention enables this setting on the installed system, its structure and its mode of operation can be seen in Fig. i and 2.
An der Achse a des Wischermotors b ist am freien Ende die Kurbel c und an einem Bund das Zahnrad d starr befestigt, die Lagerung erfolgt in den Lagerbuchsen e. Zwischen dem Zahnrad d und der inneren Lagerbuchse e ist lose auf der Achse a ein zweites, schmales Zahnrad f vorgesehen, das mit dem breiteren Zahnrad d Zähnezahl und Eingriff in das gleiche Ritzel i gemeinsam hat. An dem Zahnrad f ist ein Stift oder Nocken g angenietet, mit dem ein Betätigungshebel h für den Park- oder Endschalter periodisch bei jeder Umdrehung der Achse a bewegt wird. Eine Druckfeder k preßt die beiden Zahnräder gegeneinander und gegen die innere Lagerbüchse e und hält sie im Eingriff mit dem Ritzel i. Um die Kurbel nach erfolgter Abschaltung des Motors in dem gewünschten Sinn zu verstellen, muß sie mit der Achse a aus dem Motorgehäuse gegen die Kraft der Feder k herausgezogen werden. Das Längsspiel der Achse a ist so bemessen, daß das Zahnrad d eben noch außer Eingriff vom Ritzel i gebracht und die gewünschte Lage der Kurbel a hergestellt werden kann. Beim Loslassen drückt die Feder k die Achse a mit Zahnrad d wieder in die Arbeitslage zurück.The crank c is rigidly attached to the free end of the axis a of the wiper motor b and the gear wheel d is rigidly attached to a collar; the bearing is in the bearing bushes e. Between the gear d and the inner bearing bush e, a second, narrow gear f is loosely provided on the axis a, which has in common with the wider gear d the number of teeth and engagement in the same pinion i. A pin or cam g is riveted to the gear f, with which an actuating lever h for the parking or limit switch is moved periodically with each revolution of the axis a. A compression spring k presses the two gears against each other and against the inner bearing bush e and keeps them in engagement with the pinion i. In order to adjust the crank in the desired direction after the motor has been switched off, it must be pulled out with the axis a from the motor housing against the force of the spring k. The longitudinal play of the axis a is dimensioned so that the gear wheel d just disengaged from the pinion i and the desired position of the crank a can be established. When released, the spring k pushes the axis a with the gear wheel d back into the working position.
Der Vorteil dieser einfachen Anordnung liegt in einer erheblich vereinfachten Montage des Motors sowie in der Möglichkeit, die Endlage der Antriebskurbel nach erfolgtem Einbau der Anlage in das Kraftfahrzeug und unter betriebsmäßigen Bedingungen nachstellen zu können.The advantage of this simple arrangement is that it is considerably simplified Assembly of the motor as well as the possibility of following the end position of the drive crank installation of the system in the motor vehicle and under operational conditions to be able to adjust.
