Description
Die vorliegende Erfindung betrifft ein hydrostatischmechanisches Leistungsverzweigungsgetriebe für Kraftfahrzeuge, insbesondere für landwirtschaftliche Nutzfahrzeuge, nach dem Oberbegriff des Anspruchs 1.The present invention relates to a hydrostatic-mechanical power split transmission for motor vehicles, especially for agricultural commercial vehicles, according to the preamble of the claim 1.
Hydrostatisch-mechanische Leistungsverzweigungsgetriebe umfassen nach dem Stand der Technik ein stufenlos verstellbares Hydrostatgetriebe mit einer volumenverstellbaren und einer volumenkonstanten Einheit, einem Summierungsgetriebe und einem Bereichsgetriebe mit mehreren schaltbaren Gängen. Die über eine Antriebswelle eingeleitete Leistung verzweigt sich zum einen zu dem Hydrostatgetriebe und zum anderen auf eine Eingangswelle des Summierungsgetriebes.Hydrostatic-mechanical power split transmission include a continuously adjustable according to the prior art Hydrostatic transmission with a volume-adjustable and a volume constant Unit, a summation gear and a range gear with several switchable gears. The above on the one hand, a drive shaft introduced power branches to the hydrostatic transmission and on the other to an input shaft of the Summing.
Durch das Summierungsgetriebe werden die Drehzahlen und Drehmomente des Hydrostatgetriebes und der Antriebsmaschine zusammengeführt. Mit Hilfe von Schaltelementen sind verschiedene Gänge anwählbar, indem die Ausgangswelle des Summiergetriebes über unterschiedliche Stirnradstufen mit der Antriebswelle gekoppelt wird.Through the summation gear the speeds and torques of the hydrostatic transmission and the drive machine merged. With With the help of switching elements, different gears can be selected by the output shaft of the summation gear over different spur gear stages coupled to the drive shaft becomes.
Aus dem Stand der Technik ist eine
Vielzahl von hydrostatisch-mechanischen Leistungsverzweigungsgetrieben
bekannt. Beispielsweise offenbart die
Derartigen Getrieben liegt jedoch das gemeinsame Problem zu Grunde, dass das ein mit einem hydrostatischmechanischen Leistungsverzweigungsgetriebe ausgerüstetes Fahrzeug im Schadensfall des Getriebes nicht auf einfache Weise abgeschleppt werden kann, da beide Leistungszweige permanent mit der Abtriebswelle gekoppelt sind.However, such gears the common problem is that the one with a hydrostatic-mechanical Power split transmission equipped vehicle in case of damage the gear cannot be towed easily, since both power branches are permanently coupled to the output shaft are.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein hydrostatisch-mechanisches Leistungsverzweigungsgetriebe zu schaffen, bei dem ein Abschleppen des Fahrzeugs im Schadensfall des Getriebes auf einfache Weise möglich ist.The present invention lies based on the task of a hydrostatic-mechanical power split transmission to create a towing of the vehicle in the event of damage of the transmission is possible in a simple manner.
Ausgehend von einem hydrostatisch-mechanischen Leistungsverzweigungsgetriebe der eingangs näher genannten Art, erfolgt die Lösung dieser Aufgabe mit den Merkmalen des Patentanspruchs 1. Vorteilhafte Ausgestaltungen gehen aus den Unteransprüchen hervor.Starting from a hydrostatic-mechanical Power split transmission of the type mentioned in the introduction takes place the solution this task with the features of claim 1. Advantageous Refinements emerge from the subclaims.
Demnach wird vorgeschlagen, ein hydrostatischmechanisches Leistungsverzweigungsgetriebe mit einer Vorrichtung zur Kraftflussunterbrechung zu versehen, so dass das Fahrzeug im Schadensfall des Getriebes abgeschleppt werden kann.Accordingly, a hydrostatic-mechanical one is proposed Power split transmission with a device for power flow interruption to provide so that the vehicle in the event of damage to the transmission can be towed.
Im Rahmen einer bevorzugten Ausführungsform ist an der Hydrostatabtriebsseite in Kraftflussrichtung hinter dem Motor eine hydraulisch betätigbare Axialklauenschaltung angeordnet, welche ein Antriebszahnrad mit dem Abtrieb des Hydrostaten mittels einer Axialklaue lösbar verbindet. Im drucklosen Zustand wird die Verbindung gelöst.In a preferred embodiment is on the hydrostatic drive side in the direction of power flow behind the Motor a hydraulically operated Axial claw circuit arranged which a drive gear with releasably connects the hydrostatic output by means of an axial claw. The connection is released when depressurized.
Eine vorteilhafte Weiterbildung sieht vor, dass der Betriebsdruck der Axialklauenschaltung der Systemdruck des Getriebes ist, so dass, wenn der Systemdruck abfällt, der Abtrieb des Hydrostaten abgekoppelt wird, wodurch ein Abschleppen des Fahrzeugs ermöglicht wird.An advantageous training sees before that the operating pressure of the axial claw circuit the system pressure of the transmission, so that when the system pressure drops, the The hydrostatic output is decoupled, causing towing of the vehicle becomes.
In einer weiteren Ausgestaltungsform kann die Klauenkupplung zusätzlich während einer Schaltung des mechanischen Getriebeteils im Öffnungssinne betätigt werden, wodurch das Leistungsverzweigungsgetriebe in allen Fahrbereichen an zwei Stellen kraftflußfrei geschaltet werden kann. Dadurch wird eine erhöhte Sicherheit erreicht.In a further embodiment can also use the claw coupling while a circuit of the mechanical transmission part in the opening direction actuated be, which makes the power split transmission in all driving ranges free of force flow in two places can be switched. This increases security.
Es besteht weiterhin die Möglichkeit, die Klauenkupplung automatisch dann zu öffnen, wenn die Steuereinheit des Getriebes während einer Schaltung erkennt, dass die zu öffnende Schaltkupplung nicht öffnet, da die Lamellen dieser Kupplung beispielsweise verschweißt sind.There is still the possibility the dog clutch automatically open when the control unit of the transmission during a circuit detects that the clutch to be opened does not open because the plates of this clutch are welded, for example.
Die Erfindung wird im folgenden anhand der Zeichnung einer bevorzugten Ausführungsform der Erfindung beispielhaft näher erläutert.The invention is illustrated below the drawing of a preferred embodiment of the invention by way of example explained in more detail.
