Description
Vom Fahrschalter gesteuerte Anzeigevorrichtung für elektrisch angetriebene und gebremste Fahrzeuge. Im Hauptpatent ist eine Anzeigevorrichtung geschützt, welche bei elektrisch angetriebenen und gebremsten Fahrzeugen dem Fahrer anzeigt, daß die Motoren die zur Bremsung benötigte Selbsterregung aufweisen, so daß sie bei eingeschalteter Bremsung Strom abgeben. Wenn vor Beginn der Bremsung die Feldwicklungen abgeschaltet sind, so fließt durch die Anzeigevorrichtung der Strom, der von der dem remanenten Magnetismus des Feldes entsprechenden .elektromotorischen Kraft erzeugt wird. Dadurch wird dem Fahrer die Bremsbereitschaft angezeigt.Display device controlled by the travel switch for electrically powered and braked vehicles. In the main patent, a display device is protected, which in electrically driven and braked vehicles indicates to the driver that the Motors have the self-excitation required for braking, so that when the Braking deliver current. If the field windings are switched off before the start of braking are, the current flows through the display device from the remanent Electromotive force corresponding to the magnetism of the field is generated. Through this readiness to brake is displayed to the driver.
Es kann nun trotzdem vorkommen, daß, wenn der Fahrschalter in die Bremsstellung gebracht wird, kein Bremsstrom auftritt. Dies kann dadurch herbeigeführt werden, daß eine Stromunterbrechung oder ein sonstiger Schaden .in der Feldwicklung vorhanden ist. Dies wird zwar durch die Anzeigevorrichtung beim Bremsen kenntlich, aber der entstandene Zeitverlust kann nachteilige Folgen haben.It can still happen that when the drive switch is in the Braking position is brought, no braking current occurs. This can be brought about by this that a power interruption or other damage .in the field winding is available. This is indicated by the display device when braking, but the resulting loss of time can have detrimental consequences.
Gemäß der vorliegenden Erfindung wird dieser Mangel dadurch beseitigt, daß die Anzeigevorrichtung in der Nullstellung in Reihe mit den Ankern und den Feldwicklungen geschaltet ist, so daß sie nicht nur erkennen. läßt, ob die Motoren die zur Bremsung benötigte Selbsterregung aufweisen, sondern auch anzeigt, ob die Feldwicklungen nebst den Zuleitungen zum Fahrschalter in Ordnung sind.According to the present invention, this deficiency is eliminated by that the display device in the zero position in series with the armatures and the field windings is switched so that they do not just recognize. lets whether the motors are used for braking have required self-excitation, but also indicates whether the field windings and the supply lines to the drive switch are OK.
In der Zeichnung ist .ein Ausführungsbeispiel des Gegenstandes der Erfindung schematisch dargestellt.In the drawing is .ein embodiment of the subject matter of Invention shown schematically.
Abb. z zeigt die Schaltung in der Nullstellung des Fahrschalters, Abb. 2 die Schaltung in der Bremsstellung; Abb.3 läßt erkennen, wie die zum Anschließen der Anzeigevorrichtung benötigten Verbindungen durch die Bewegung des Fahrschalters hergestellt werden.Fig.z shows the circuit in the zero position of the drive switch, Fig. 2 shows the circuit in the braking position; Fig.3 shows how to connect the display device required connections by moving the drive switch getting produced.
In Abb. r ist angenommen, daß das Fahrzeug sich in Bewegung befindet und der Fahrschalter die Nullstellung hat. Die Feldwicklungen sind mit den Ankern der leer laufenden Motoren verbunden, und mit der Anzeigevorrichtung zu einem Kreis geschlossen. Ist dieser Kreis an irgendeiner Stelle infolge eines Motor- oder Leitungsschadens o. dgl. unterbrochen oder haben die Motoren aus anderen Gründen nicht die zum Bremsen nötige Selbsterregung, so erkennt der Fahrer dies schon vor der Bremsung aus dem Nichtansprechen der Anzeigevorrichtung.In Fig. R it is assumed that the vehicle is in motion and the travel switch is in the zero position. The field windings are with the anchors the idling motors connected, and with the display device in a circle closed. Is this circuit at any point as a result of engine or line damage The like. Interrupted or the motors for other reasons do not have the braking necessary self-excitation, so the driver recognizes this from the before braking Failure to respond to the display device.
Bei der in Abb. z angedeuteten Bremsstellung ist die Anzeigevorrichtung ebenso geschaltet und wirkt ebenso wie im Hauptpatent. Das dargestellte Ausführungsbeispiel ist für ein übliches Fahrzeug mit zwei Motoren ;geeignet. Die Änderungen für eine andere Motorenanzahl ergeben sich ohne weiteres.In the braking position indicated in Fig. Z, the display device is switched in the same way and works just like in the main patent. The illustrated embodiment is suitable for a common vehicle with two engines. The changes for a other numbers of engines are readily available.
