Description
Die vorliegende Erfindung bezieht sich auf eine Regelungsanordnung für die elektrische Kraftübertragung bei brennkraftelektrischen Triebfahrzeugantrieben mit von einem Generator gespeisten und parallelgeschalteten Fahrmotoren, bei der die Generatorregelung im Sinne einer Leistungsregelung auf Grund einer Strom- und Spannungsmessung erfolgt, der als Signal über die Stromstärke der Fahrmotoren nur der Strom eines Fahrmotors oder einer Fahrmotorengruppe zugeführt ist, so daß beim Auftreten eines Schleudervorganges an einem anderen Fahrmotor dieser mit unveränderlicher Generatorspannung arbeitetThe present invention relates to a control arrangement for the electrical power transmission with internal combustion-electric traction vehicle drives Traction motors powered by a generator and connected in parallel, in which the generator control is in In the sense of a power control based on a current and voltage measurement, which is sent as a signal via the Amperage of the traction motors only supplied the current of a traction motor or a group of traction motors is, so that when a skid occurs on another drive motor this with unchangeable Generator voltage is working
Eine Regelungsanordnung dieser Art ist aus der französischen Patentschrift 13 37 022 oder der dieser entsprechenden deutschen Offenlegungsschrift 14 13 653 bekannt Bei dieser bekannten Ausbildung wird von den Strömen zweier Fahrmotorengruppen der größere der zwei gemessenen Ströme als Istwert für die Regelung verwendet.A control arrangement of this type is from French patent 13 37 022 or the corresponding one German Offenlegungsschrift 14 13 653 known In this known training is of the currents of two traction motor groups, the larger of the two measured currents as the actual value for the control used.
Ein Nachteil dieser bekannten Anordnung zeigt sich, wenn diejenige Achse anfängt zu schleudern, deren größter Strom bis dahin den Istwert für die Regelung geliefert hat Es wird dann infolge der Stromabnahme an der schleudernden Achse ein kleinerer Strom eines anderen Motors bzw. einer anderen Motorgruppe den Istwert liefern und die Regelung im Sinne einer Leistungssteigerung beeinflussen. Auf diese Weise wird also bei nicht genau gleichen Strommeßwerten doch eine Beeinflussung der Generatorspannung durch einen Schleudervorgang erfolgen und die eintretende Zugkrafterhöhung die noch nicht schleudernden Aehse.i ebenfalls zum Schleudern bringen.A disadvantage of this known arrangement becomes apparent when that axis begins to spin, its The largest current until then has delivered the actual value for the control. It is then due to the current consumption A smaller current from another motor or another motor group denotes the skidding axis Deliver the actual value and influence the control in the sense of an increase in performance. That way will So if the measured current values are not exactly the same, the generator voltage is influenced by one Skidding process take place and the resulting increase in pulling force the Aehse.i which are not yet skidding also make it spin.
Außerdem kann schon die Umscnaltung von einem Meßwertgeber auf einen anderen Meßwertgeber einen Spannungsstoß verursachen. Die hiermit verbundenen Stromstöße werden von Zugkraftscößen an den nicht schleudernden Achsen begleitet Diese fallen zeitlich mit dem Beginn des Schleuderns an den Achsen zusammen, die an der Grenze der Haftreibung standen, d. h. ίο mit dem Augenblick, in dem die Haftbedingungen für alle Achsen schlechter werden. Dies hat *ijch hier zur Folge, daß das Schleudern auf weiter* achsen übergreift In addition, switching from one transducer to another can be a Cause voltage surge. The associated current surges are not generated by tensile forces on the accompanies skidding axes These coincide with the start of skidding on the axes, which were at the limit of static friction, d. H. ίο from the moment the conditions of detention for all axes get worse. This has to be done here The result is that the skid spreads to further axes
Aufgabe der vorliegenden Erfindung ist es, bei einer Anordnung der eingangs beschriebenen Art zu verhindern, daß ein eventuell auftretendes Schleudern auf weitere Achsen übergreifen kann.The object of the present invention is to prevent in an arrangement of the type described above, that any skidding that may occur can spread to other axes.
Zur Lösung dieser Aufgabe wird erfindungsgemäßAccording to the invention, this object is achieved
vorgeschlagen, daß als Stromsignal der Summenstrom der Fahrmotoren derjenigen Radsätze dient, w Jene bei der gegebenen Fahrtrichtung am wenigsten zum Schleudern neigen.suggested that the total current of the traction motors of those wheelsets is used as the current signal, w those have the least tendency to skid in the given direction of travel.
Bei dieser Anordnung werden nicht nur Spannungsund Stromstöße vermieden, sondern es werden auch nur eine geringere Anzahl von Meßeinrichtungen und Umformern benötigt, so daß die Anordnung weniger aufwendig wird.With this arrangement, not only are voltage and current surges avoided, but there are only a smaller number of measuring devices and converters required, so that the arrangement is less becomes expensive.
Bei der praktischen Ausführung der Erfindung werden alle elektrischen Fahrmotoren (z. B. einer Diesellok) so in Gruppen unterteilt, daß die Radsätze, deren Neigung zum Schleudern ungefähr gleich ist, zu einer G ruppe gehören. Der Elektromotorenstrom wird ebenfalls gruppenweise gemessen.In the practical implementation of the invention, all electric traction motors (e.g. a diesel locomotive) so divided into groups that the wheelsets, whose tendency to skid is approximately the same, to one Belong to the group. The electric motor current is also measured in groups.
Während des Fahrbetriebs der Diesellok werden, vor altern unter der Wirkung der Kraft am Zughaken, aber auch bei Steigungen und Gefällestrechen die Achslasten neu verteilt. Hierbei wird ein Teil der Radsätze, in der Regel die hinteren Radsätze, zusätzlich belastet und der andere Teil entlastet. Beim Ändern der Fahrrichtung wechseln diese Radsatzgruppen symmetrisch ihre Plätze.During operation the diesel locomotive will age under the effect of the force on the towing hook, however The axle loads are redistributed even on inclines and declines. Here part of the wheelsets, in Usually the rear wheelsets are additionally loaded and the other part is relieved. When changing the direction of travel these wheelset groups change their places symmetrically.
Meßeinrichtungen und Umformer werden an die Fahrmotorgruppen angeschlossen, die mit den eine Zusiitzbelastung erfahrenden Radsatzgruppen verbunden sind. Dadurch wird der Strom gruppenweise in den Kreisen der Elektromotoren gemessen, die mit Radsätzen verbunden sind, welche am wenigsten zum Schleudern geneigt sind.Measuring devices and converters are connected to the traction motor groups with an additional load experienced wheelset groups are connected. This causes the current to flow in groups into the Circles of the electric motors are measured, which are connected to wheelsets, which least to skid are inclined.
Wenn eine oder mehrere der anderen Radsätze zu schleudern beginnen, gehen die Fahrmotoren zu einer Arbeitsweise über, bei der konstante Fahrgeneratorspannung aufrechterhalten wird, wodurch es unmöglich wird, daß auch andere Radsätze zu schleudern beginnen. Daher kommt die Schleuderbewegung zu Ende.If one or more of the other wheel sets start to skid, the traction motors will go to one Operation over, at which constant drive generator voltage is maintained, making it impossible that other wheelsets will also begin to skid. Therefore the sling motion comes to an end.
