Patentiert im Deutschen Reiche vom 23. März 1915 ab.Patented in the German Empire on March 23, 1915.

Das Vorhandensein eines Differentialgetriebes im Antriebswerke von Kraftfahrzeugen ist die Ursache mancher unangenehm empfundener Vorgänge bei der Fahrt, wie Gleiten der Räder wegen zu geringer Adhäsion u. dgl. Um dem entgegenzuarbeiten, sind nun wohl Einrichtungen vorgeschlagen worden, die ermöglichen, das Differentialgetriebe festzustellen und damit seine Einwirkung aufzuheben.The presence of a differential gear in the drive train of motor vehicles is the The cause of some unpleasant processes while driving, such as sliding the wheels due to insufficient adhesion and the like. To counteract this, there are now facilities have been proposed that make it possible to determine the differential gear and thus cancel its action.

ίο Die bisher angewendeten Mittel, denen zufolge entweder auf der Nabe des Differentialgehäuses eine Klauenkupplung verschiebbar sitzt oder die Klauenkupplung auf der Welle verschiebbar sitzend durch Federn von der Welle mitgenomiuen wird, sind mit erheblichen Nachteilen verbunden. Im ersteren Falle bedingt die zwischen Differentialgehäuse und Lager liegende Kupplungshülse das Herausrücken dieses Lagers oder das gänzliche Fortlassen desselben. Beide Maßnahmen führen zur Vergrößerung des Abstandes des Zahndruckangriffes vom Lager und damit der Abmessungen der entsprechenden Teile, weil größere Biegungsmomente auftreten. Zweiten Falles bei auf der Welle sitzender Kupplungshülse kann man zwar das Lager nahe dem Differentialgehäuse belassen, doch ist es notwendig, da die Kupplungshülse außerhalb des Lagers liegt, das Differentialgehäuse bzw. die Nabe dieses durch das Lager hindurchzuführen. Dabei ist es nicht zu vermeiden, daß bei dem nur möglichen kleinen Kupplungsdurchmesser die Drücke in den Klauen so groß werden, daß nicht immer der konstruktiv zulässige Flächendruck erreichbar ist. Auch besitzt diese zweite Ausführungsmöglichkeit den Mangel, daß beim Herausziehen derjenigen Welle, auf welcher die Kupplungshülse sitzt, die letztere herunterfällt und beim Wiedereinbringen der Welle nicht selten schwer auffindbar ist oder auch ganz vergessen werden kann. Zur Beseitigung dieser Gefahr muß dann zu anderen konstruktiven Mitteln gegriffen werden, wie eine nochmalige Lagerung der Kupplungshülse in dem Differentialgehäuse u. dgl. m.ίο The means used so far, according to which either a claw coupling is slidably seated on the hub of the differential housing or the claw coupling is on the shaft slidably seated by springs from the shaft are mitgenomiuen are with considerable Associated disadvantages. In the former case, the difference between the differential housing and Coupling sleeve lying on the bearing, moving out this bearing or omitting it entirely same. Both measures lead to an increase in the distance between the tooth pressure attack from the bearing and thus the dimensions of the corresponding parts, because larger bending moments occur. Second If the coupling sleeve is seated on the shaft, the bearing can be close to the Leave the differential housing, but it is necessary because the coupling sleeve is outside the bearing is to pass the differential housing or the hub this through the bearing. Included it cannot be avoided that with the only possible small coupling diameter the The pressures in the claws become so great that the surface pressure that is structurally permissible is not always the same is attainable. This second embodiment also has the shortcoming that when Pull out that shaft on which the coupling sleeve sits, the latter falls down and when the shaft is reinserted it is often difficult to find, or even can be completely forgotten. To eliminate this danger, other constructive ones must then be used Means are used, such as a repeated storage of the coupling sleeve in the Differential housing and the like.

Beim vorliegenden Erfindungsgegenstande sind vorstehende Mängel beseitigt unter Belassen des Lagers nahe am Differentialgehäuse. Dieser in der Beseitigung der Mängel wurzelnde Fortschritt wird dadurch erzielt, daß die Kupplungshülse auf dem Differentialgehäuse selbst gelagert ist und nicht auf der Nabe desselben, ebensowenig auf einer der Antriebswellen. Zwischen Lager und Kupplungshülse befindet sich nun nur noch eine senkrecht oder annähernd senkrecht zur Achse verlaufende Wand der Kupplungshülse zur Aufnahme der Kupplungsklauen.In the present subject matter of the invention, the above deficiencies have been eliminated and left as they are of the bearing close to the differential housing. This one rooted in the elimination of the shortcomings Progress is achieved in that the coupling sleeve on the differential housing itself is mounted and not on the hub of the same, just as little on one of the drive shafts. Between the bearing and the coupling sleeve there is now only one wall of the coupling sleeve running perpendicular or approximately perpendicular to the axis Mounting of the coupling claws.

Die vorliegende Sperrung kann bei Kettenwagen wie bei Kardanwagen Anwendung finden; bei letzterem ist dann die Sperrung in die Hinterachse, die Kardanachse, einzubauen. The present blocking can be used in chain cars as in cardan cars; in the latter case, the lock must be installed in the rear axle, the cardan axle.

Die Erfindung wird auf der Zeichnung nach einem Schnitt, Fig. 1, durch eine Kardanachse dargestellt, während Fig. 2 einen Schnitt nach a, b der Antriebswelle veranschaulicht. Das Kupplungsstück 1 ist auf dem Differentialge-The invention is shown in the drawing according to a section, FIG. 1, through a cardan shaft, while FIG. 2 illustrates a section according to a, b of the drive shaft.

Die Klauen 3 des Kupplungsstückes 1 greifen durch entsprechende Löcher im Differentialgehäuse hindurch in die Klauen 4 eines Kegelrades 7, welches von der Welle 5, von Federn 6, mitgenommen wird. Die Kupplung 1 ist mit einer Laufrinne 8 versehen, in welche das Ende 11 eines im Gehäuse 12 gelagerten Stellhebels 9 in bekannter Weise eingreift. Eine Bewegung des Hebels 9 durch Vermittlung einer aus dem Gehäuse nach außerhalb reichenden Welle 10 hat die Verschiebung der Kupplung 1 auf dem Differentialgehäuse 2 zur Folge, womit im Bedarfsfalle das Differentialgehäuse festgelegt werden kann.
