Description
Verfahren zum Herabsetzen der Höchstzugkraft bei elektrisch gekuppelten, ferngesteuerten Fahrzeugen Bei einem aus mehreren Lokomotiven bestehenden Vorspann kann die an den Zughaken zur Auswirkung kommende Zugkraft so groß werden, daß diese reißen.Procedure for reducing the maximum tensile force in electrically coupled, remote-controlled vehicles In the case of a leader consisting of several locomotives the tensile force acting on the draw hook can be so great that this tear.
Bei elektrisch gekuppelten, ferngesteuerten Fahrzeugen kann dieses Gefahrenmoment durch ein Verfahren nach der vorliegenden Erfindung vermieden werden. Dieses besteht darin, daß in jedem Einzelfahrzeuge das Übersetzungsverhältnis zwischen dem Fahrmotorstrom und dem Auslösestrom des Maximalrelais zwangsläufig geändert wird, sobald der Hauptschalter und die Motorschalter der elektrisch gekuppelten Fahrzeuge eingeschaltet sind.In the case of electrically coupled, remote-controlled vehicles, this can Danger moments can be avoided by a method according to the present invention. This consists in the fact that in each individual vehicle the gear ratio between the traction motor current and the tripping current of the maximum relay inevitably changed becomes as soon as the main switch and the motor switch are electrically coupled Vehicles are switched on.
In der Zeichnung ist ein Ausführungsbeispiel einer Einrichtung zur Ausübung des Verfahrens nach der vorliegenden Erfindung veranschaulicht.In the drawing is an embodiment of a device for Practice of the method of the present invention illustrated.
An einer vorhandenen durchgehenden Zugsteuerleitung i, die auf sämtlichen Fahrstufen nur vom Führerschalter des führenden Fahrzeuges aus Spannung erhält, ist in jedem Einzelfahrzeuge die Spule eines Umschaltrelais 5 angeschlossen. Auf der anderen Seite ist diese Spule jeweils an eine besondere durchgehende Steuerleitung 2 angeschlossen, die ihrerseits mit der Steuerleitung 3 des jeweils benachbarten Fahrzeuges über die Steuerstromkupplung verbunden ist. Die Steuerleitung 3 eines jeden Einzelfahrzeuges ist schließlich über einen in der Einschaltstellung des Hauptschalters geschlossenen Hilfskontakt 6 und - in Reihe damit - über die in der Einschaltstellung geschlossenen Hilfskontakte 7 bis i o der Motorschalter (z. B. der Trennschütze, der Fahrtwenderschütze u. dgl.) geerdet. Sind in einem Einzelfahrzeuge mehrere Motorschalter vorhanden, so werden ihre Hilfskontakte vorteilhaft sämtlich parallel geschaltet.On an existing through train control line i, which is on all Driving steps only receives voltage from the driver's switch of the leading vehicle, the coil of a changeover relay 5 is connected in each individual vehicle. on on the other hand, this coil is connected to a special continuous control line 2 connected, in turn with the control line 3 of the neighboring Vehicle is connected via the control current coupling. The control line 3 of a Each individual vehicle is finally in the on position of the main switch via one closed auxiliary contact 6 and - in series with it - via the in the switch-on position closed auxiliary contacts 7 to i o the motor switch (e.g. the isolating contactor, the reversing contactor etc.) grounded. There are several engine switches in a single vehicle present, their auxiliary contacts are advantageously all connected in parallel.
Eine solche Einrichtung wirkt nun derart. daß die Umschaltrelais 5 anziehen, sobald mehrere Einzelfahrzeuge miteinander gekuppelt, die durchgehende Zugsteuerleitung i vom führenden Fahrzeuge aus an Spannung gelegt und die Hauptschalter sowie die Fahrmotorschalter eingeschaltet sind. Durch das Anziehen der Umschaltrelais 5 ändert sich dann das Übersetzungsverhältnis zwischen dem vom Fahrmotorstrom - entsprechend der durch das Fahrzeug ausgeübten Zugkraft - beeinflußten Niederspannungs-Stromwandler 12 und dem dazugehörigen Niederspannungs-Maximalrelais i i derart, daß dieses bereits anspricht, wenn das Fahrzeug eine geringere Zugkraft ausübt als bei Einzelfahrt. Durch das Niederspannungs-Maximalrelais i i wird dann entweder der Steuerstrom abgeschaltet. der Hauptschalter ausgeschaltet oder aber der Führer durch ein Warnungssignal auf die Gefahrengrenze aufmerksam gemacht.Such a device now works in this way. that the changeover relay 5 as soon as several individual vehicles are coupled together, put on the continuous Voltage is applied to the train control line i from the leading vehicle and the main switch and the traction motor switches are switched on. By tightening the changeover relay 5 then changes the transmission ratio between that of the traction motor current - according to the tensile force exerted by the vehicle - influenced low-voltage current transformer 12 and the associated low-voltage maximum relay i i such that this already responds when the vehicle exerts less tractive effort than when traveling alone. The control current is then either switched off by the low-voltage maximum relay i i. the main switch switched off or the Guide by a warning signal made aware of the danger limit.
Die beabsichtigte Änderung des übersetzungsverhältnisses erfolgt dabei durch die Änderung der Windungszahl des Niederspannungs-Maximalrelais i i, und zwar kann diese Änderung entweder durch Abschalten eines Teiles der unterteilten Relaiswicklung bewirkt werden oder aber in der Weise, daß das für Einzelfahrt vorgesehene Relais i il, ab- und ein niedriger eingestelltes Relais i i" an seiner Stelle zugeschaltet wird.The intended change in the transmission ratio takes place by changing the number of turns of the low-voltage maximum relay i i, namely this change can either be achieved by switching off part of the subdivided relay winding be effected or in such a way that the relay intended for single travel i il, off and a lower set relay i i "switched on in its place will.
