Abstract
Description
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Auflösen einer Zahn-auf-Zahn-Stellung von Zähnen der Schalteinrichtung zwischen einem ersten Getriebe und einem nachgeschalteten Getriebe gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a method for dissolving a tooth-on-tooth position of teeth the switching device between a first gear and a downstream Transmission according to the preamble of Patent claim 1.
Aus dem Stand der Technik ist bekannt, nachgeschaltete Getriebe als klauengeschaltete Getriebe auszuführen. Bei klauengeschalteten Getrieben kann es beim Gangeinlegen bei nicht drehenden Wellen, beispielsweise im Stillstand zu Zahn-auf-Zahn-Stellungen in der Klauenschaltung kommen, wodurch das Gangeinlegen in nachteiliger Weise verhindert wird und ein erhöhter Verschleiß der Bauteile verursacht wird.Out the prior art is known, downstream transmission as to perform claw-connected gear. With claw-connected It can be driven during gear engagement with non-rotating shafts, for example, at a standstill to tooth-on-tooth positions in the Claw switching come, whereby the gear engagement disadvantageously is prevented and an elevated Wear the Components is caused.
Derartige klauengeschalteten Getriebe können z. B. ein Wendegetriebe, ein schaltbares Verteilergetriebe oder ein schaltbarer Nebenabtrieb in Straßenfahrzeugen, Schienenfahrzeugen oder Arbeitsmaschinen sein; in der Regel sind diese klauengeschalteten Getriebe in einem Antriebsstrang mit einer Antriebsmaschine und einem Wechselgetriebe eingebaut.such can claw-connected transmission z. B. a reversing gear, a switchable transfer case or a switchable power take-off in road vehicles, rail vehicles or work machines; usually these are claw-connected Transmission in a drive train with a prime mover and installed a change gear.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Auflösen einer Zahn-auf-Zahn-Stellung von Zähnen der Schalteinrichtung zwischen einem ersten Getriebe und einem nachgeschalteten Getriebe anzugeben, welches einfach durchführbar ist und keine zusätzlichen Bauteile benötigt.Of the The present invention is based on the object, a method to dissolve a tooth-on-tooth position of teeth of the switching device between a first transmission and a downstream transmission specify which is easy to perform and no additional Components needed.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further Embodiments of the invention and advantages are apparent from the dependent claims.
Demnach wird vorgeschlagen, eine Zahn-auf-Zahn-Stellung der Schalteinrichtung zwischen einem ersten Getriebe und einem nachgeschalteten Getriebe durch Verdrehen der Eingangswelle bzw. der Antriebswelle des nachgeschalteten Getriebes aufzulösen.Therefore It is proposed a tooth-on-tooth position of the switching device between a first transmission and a downstream transmission by rotating the input shaft or the drive shaft of the downstream transmission dissolve.
In einem ersten Schritt des erfindungsgemäßen Verfahrens wird eine Zahn-auf-Zahn-Stellung dadurch erkannt, dass der Schaltweg der Schalteinrichtung des nachgeschalteten Getriebes nicht die Endstellung erreicht, sondern in einer Zwischenstellung verharrt. Diese Zwischenstellung wird von einem Steuergerät erkannt und leitet beim ersten Getriebe, was in der Regel als Wechselgetriebe ausgebildet ist – im Rahmen einer Weiterbildung der Erfindung erst nach einer Wiederholung des Schaltversuches – ein Verdrehen des Abtriebs, d. h. des Antriebs des nachgeschalteten Getriebes, ein.In a first step of the method according to the invention becomes a tooth-on-tooth position recognized that the switching path of the switching device of the downstream Gear not reached the end position, but in an intermediate position remains. This intermediate position is detected by a control unit and directs the first gearbox, which is usually called a change gearbox is trained - in Within a further development of the invention only after a repetition of the shift attempt - a Twisting the output, d. H. the drive of the downstream Gear, a.
Voraussetzung für das Verdrehen der Eingangswelle des nachgeschalteten Getriebes ist, dass die Antriebsmaschine des ersten Getriebes, beispielsweise mit Leerlaufdrehzahl, läuft.requirement for the Twisting the input shaft of the downstream transmission, that the prime mover of the first transmission, for example with Idling speed, running.
Für den Fall, dass das erste Getriebe als automatisiertes Schaltgetriebe ausgeführt ist, wird ein möglichst kleiner Gang eingelegt und die entsprechende Kupplung langsam geschlossen, so dass die Eingangswelle des nachgeschalteten Getriebes verdreht wird. Dadurch wird die Zahn-auf-Zahn-Stellung aufgelöst und die Schaltung kann beendet werden.In the case, that the first transmission is designed as an automated manual transmission, becomes one as possible engaged in a small gear and the corresponding clutch slowly closed, so that the input shaft of the downstream transmission is rotated becomes. As a result, the tooth-on-tooth position is resolved and the Circuit can be ended.
Bei einem Wandler-Lastschaltgetriebe als vorgeschaltetem Getriebe wird die Eingangswelle des nachgeschalteten Getriebes durch Schließen einer Schaltkupplung mit Hilfe des Wandlerschleppmomentes verdreht.at a converter power shift transmission as an upstream transmission is the input shaft of the downstream transmission by closing a Clutch with the help of the torque converter torque twisted.
Gemäß der Erfindung ist vorgesehen, dass sobald am Abtrieb des ersten Getriebes ein Drehen der Welle erkannt wird, der Unterstützungs- bzw. Drehvorgang abgebrochen wird. Einerseits reicht das Verdrehen der Welle um einige Grade aus, um die Zahn-auf-Zahn-Stellung aufzulösen und andererseits würde sonst durch Schließen des gesamten Antriebsstranges das Fahrzeug ungewollt anfahren oder ein Anfahrruck entstehen.According to the invention is provided that once at the output of the first transmission a Turning the shaft is detected, the support or rotation stopped becomes. On the one hand, the twisting of the shaft is just a few degrees to dissolve the tooth-on-tooth position and otherwise would otherwise by closing the entire drive train, the vehicle unintentionally start or a starting pressure arise.
Ist das Auflösen der Zahn-auf-Zahn-Stellung erfolgreich beendet und ein sofortiger Anfahrwunsch (z. B. abgeleitet von der Fahrpedalstellung) vorhanden, kann die Kupplung auch kontinuierlich weiter schließen und muß nicht zwingend geöffnet werden.is dissolving the tooth-on-tooth position ended successfully and an immediate one Approach request (eg derived from accelerator pedal position) available, can also continue to close the clutch continuously and does not have to mandatory opened become.
Die beschriebene Steuerung bzw. Funktionalität kann sowohl in einem Getriebesteuergerät, in einen Achssteuergerät, in einem zentralen Antriebsstrang-Steuergerät oder aufgeteilt zwischen diesen Steuergeräten realisiert werden.The described control or functionality can both in a transmission control unit, in a Achssteuergerät, in a central powertrain control unit or split between these controllers will be realized.
