Yorrichtung zum Kühlen von Spülöl in hydrostatischen Getrieben mit geschlossenem reversierbarem Kreislauf.Y or device for cooling flushing oil in hydrostatic gears with closed reversible circuit.

Die Erfindung bezieht sich auf eine Vorrichtung zum Kühlen von Spülöl in hydrostatischen Getrieben mit geschlossenem reversierbarem Kreislauf. Bei Getrieben dieser Art ist es erforderlich, das Rücklauföl im geschlossenen Kreislauf mit einigen Atmosphären vorzuspannen. Dieses geschieht mit einem Vorspannventil, wobei hinter diesem das entspannte Spülöl einem Ölkühler zufliesst, der zusätzlich von einem Lüfter belüftet werden muss. Dieses vorgespannte Öl bedeutet Wirkungsgradverlust. Desgleichen braucht der Lüfter zusätzliche Antriebsleistung.The invention relates to a device for cooling flushing oil in hydrostatic transmissions with closed reversible circuit. In the case of transmissions of this type, it is necessary to keep the return oil in a closed circuit to bias with some atmospheres. This is done with a preload valve, with the relaxed one behind this Flushing oil flows to an oil cooler, which must also be ventilated by a fan. This biased Oil means a loss of efficiency. The fan also needs additional drive power.

Sinn und Zweck der vorliegenden Erfindung ist es, den Wirkungsgrad einer derartigen Anlage zu verbessern und zwar dadurch, dass das Spülöl nicht über ein Vorspa^nventil unter Druck gesetzt wird, sondern ein Zahnradmotor die Aufgabe dieses Vorspannventils übernimmt, der den für die Kühlung benötigten Luftstrom erzeugt.The whole purpose of the present invention is to improve the efficiency to improve such a system, namely in that the flushing oil does not have a pre-pressure valve is pressurized, but a gear motor takes over the task of this preload valve, which is responsible for the Cooling required air flow generated.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing is an embodiment of the invention shown.

Ein hydrostatisches Getriebe mit geschlossenem und reversierbarem Kreislauf besteht aus der Pumpe 1 und dem Motor Die Zahnradpumpe 3 drückt Spülöl über die Rückschlagventile 4 und 5 in die jeweilige lüederdruckseite. Über das Spülventil 6 wird erhitztes Kreislauföl in entsprechend der von der Zahnradmotorpumpe 3 zugeführten Spülölmenge in die Leitung 7 geführt. Über diese Leitung 7 wird das erhitzte Spülöl in den Zahnradmotor 8 geleitet, derA hydrostatic transmission with closed and reversible Circuit consists of pump 1 and the motor The gear pump 3 presses flushing oil through the check valves 4 and 5 into the respective lüederdruckseite. About the Flushing valve 6 is heated circulating oil in accordance with the amount of flushing oil supplied by the gear motor pump 3 led into line 7. Via this line 7, the heated flushing oil is passed into the gear motor 8, the
