Description

Die Erfindung :bezieht sich auf eine Kurbelanordnung für Fahrschalter bei elektrischen Fährzeugen, insbesondere Straßenbahnwagen, elektrischen Lokomotiven uAgl. Bis jetzt war es üblich, dieKürbel und den für die Blockierung dienenden Hebel an j e einer besonderen Achse zu lagern.The invention: relates to a crank arrangement for travel switches in electric vehicles, especially trams, electric locomotives etc. Up until now it was common to use the paddles and the locking lever to be stored on each of a special axis.

Demgegenüber zeichnet sich die Erfindung im wesentlichen dadurch aus, daß die Kurbelachse in einem gleichzeitig als Lager für den Blockierungs= hebel dienenden Lagerrohr gelagert ist. Hierdurch wird nicht nur an Werkstoff gespart, sondern auch der Platz, der für die Lagerung der Achsen zur Verfügung steht, wird besser als beiden bisherigen Bauarten ausgenutzt.In contrast, the invention is essentially characterized by that the crank axis in one at the same time as a bearing for the blocking = lever serving bearing tube is stored. This not only saves on material, but also the space that is available for storing the axles better used than both previous designs.

In der Zeichnung isst die Erfindung in einem Ausführungsbeispiel dargestellt.In the drawing, the invention is shown in one embodiment.

Mit i ist die Kurbel bezeichnet, deren Achse 2 mit Hilfe eines Kugellagers 3 in einem abgesetzten Lagerrohr 5 gelagert ist, das an einer oberen Platte q. eines z. B. rahmenartigen Fahrschalterträgers befestigt ist.With i the crank is referred to, the axis 2 with the help of a ball bearing 3 is mounted in a remote bearing tube 5, which q on an upper plate. one z. B. frame-like travel switch support is attached.

Das Lagerrohr 5 ist an seinem äußeren unteren Teil abgedreht, so daß es zugleich als Lager für den Blockierungshebel 6 dient, dessen naibenförmiger Teil den unteren abgedrehten Teil des Lagerrohres und ein Kugellager 7 für den Blockierungshebel 6 umschließt. Der Blockierung.shebel arbeitet mit der Fahrtwendewalze zusammen und blockiert in an sich bekannter Weise den Fahrschalter derart, daß zu einem Zeitpunkt, in dem die Fahrtwendewalze auf Null steht, dieser nicht betätigt werden kann. Gleichzeitig wird die Fahrtwendewalze blockiert, wenn der Fahrschalter auf einer anderen Stellung als auf Null steht. Der Hebel übernimmt außerdem die Betätigung der Fahrtwendewalze.The bearing tube 5 is turned off at its outer lower part, so that it also serves as a bearing for the blocking lever 6, the hub-shaped part of which the lower turned part of the bearing tube and a ball bearing 7 for the locking lever 6 encloses. The blocking lever works together with the travel reversing roller and blocks the drive switch in a manner known per se in such a way that at a point in time in which the turnaround roller is at zero, this cannot be operated. Simultaneously the drive turning roller is blocked when the drive switch is in a different position than is zero. The lever also actuates the drive turning roller.
