Abstract
Hydraulische
Antriebsvorrichtung bestehend aus einem
Description
Die Erfindung betrifft eine hydraulische Antriebsvorrichtung für Anbauverdichter anzubauen an verschiedene Trägergeräte, wie Bagger, Radlader, Traktoren usw. Diese Verdichter lassen sich über Schnellwechselvorrichtungen sehr schnell an die Trägergeräte anbauen. Zum Antrieb der Unwuchtwellen im Erregergetriebe wird ein Ölmotor benutzt. Dieser wird mit zwei Hydraulikschläuchen mit dem Trägergerät verbunden. Ein Schlauch für die druckführende und ein Schlauch für die ölrückführende Seite. Da jeder schnelllaufende Ölmotor mit einem Leckölanschluss ausgerüstet ist, muss noch eine dritte Leitung – eine sogenannte Leckölleitung – vorgesehen sein. Diese führt das Lecköl, das innerhalb des Motors auftritt, druckfrei in den Tank zurück. Bei allen bekannten Maschinen ist diese meistens nicht vorgesehen. Es ist auch nicht möglich, den Leckölschlauch mit der rückführenden Seite zu verbinden, da es oft zu starken Rückstaudrücken in dieser Leitung kommt. Diese entstehen dadurch, dass der Rücklauf meistens durch einen Steuerschieber und einen Hydraulikfilter geführt wird. Da der Bediener am Anfang nicht merkt, dass der Leckölschlauch nicht richtig angeschlossen ist, kommt es oft zu erheblichen Ausfällen und Stillstandzeiten, verbunden mit erheblichen Folgekosten. Wenn das Lecköl nicht relativ drucklos abgeführt wird, kann es zu enormen Schäden führen. So werden die Radialwellendichtringe des Ölmotors beschädigt, das Erregergetriebe läuft mit Öl voll, und es treten Hitzeschäden im Getriebe auf. Bis jetzt gab es nach dem Stand der Technik keine Vorrichtung, die das Problem zufriedenstellend gelöst hat.The The invention relates to a hydraulic drive device for add-on compactors to be attached to various carrier devices, such as Excavators, wheel loaders, tractors, etc. These compressors can be controlled by quick-change devices grow very quickly to the carrier equipment. To drive the imbalance shafts in the exciter transmission, an oil motor is used. This comes with two hydraulic hoses connected to the carrier. A hose for the pressure-bearing and a hose for the oil returning side. Because every high-speed oil engine with a leak oil connection equipped is, still a third line - a so-called leak oil line - provided be. This leads the leak oil, that occurs inside the engine, returns to the tank pressure-free. At all known machines this is usually not provided. It is also not possible the leak oil hose with the returning To connect side, as it often comes to strong back pressure in this line. These arise from the fact that the return mostly by a Control slide and a hydraulic filter is performed. Since the operator on Beginning does not notice that the drain hose is not connected properly is often significant failures and downtime, associated with significant follow-up costs. If the leak oil is not relative discharged without pressure It can cause enormous damage to lead. Thus, the radial shaft seals of the oil motor are damaged, the Exciter gear runs with oil full, and heat damage occurs in the transmission. So far, there was none according to the state of the art Device that has solved the problem satisfactorily.
