Description

Die Erfindung bezieht sich auf eine Hydraulikanlage in Verbindung mit einem Getriebe, insbesondere Hydraulik- bzw. Kraftheberanlage für Ackerschleppergetriebe, wobei das Ölfilter der Hydraulikanlage innerhalb des Getriebegehäuses oder eines mit diesem in räumlicher Verbindung stehenden Behälters angeordnet ist und die Hydraulikanlage aus einem ölfilter, einer Pumpe, die über die Saugleitung mit dem Innenraum des ölfilters verbunden und deren Druckleitung über eine Steuereinrichtung an den Arbeitszylinder angeschlossen ist, besteht.The invention relates to a hydraulic system in connection with a transmission, in particular Hydraulic or power lift system for farm tractor transmissions, with the oil filter of the hydraulic system inside the gear housing or a container that is spatially connected to it is arranged and the hydraulic system consists of an oil filter, a pump, which via the suction line with connected to the interior of the oil filter and its pressure line via a control device to the Working cylinder is connected, consists.

Es ist eine Kraftheberanlage von Ackerschleppern dieser Art bekannt, die mittels Getriebeöl betrieben wird, wobei das Öl aus dem Sumpf des Getriebes durch einen Filter angesaugt wird. Der Ölrücklauf wird bei dieser bekannten Kraftheberanlage nicht durch das Filter geleitet. Es ist daher erforderlich, daß das in der Kraftheberanlage befindliche Öl stets frisch angesaugt wird.A power lift system for agricultural tractors of this type is known, which is operated by means of gear oil the oil is sucked from the sump of the transmission through a filter. The oil return is not passed through the filter in this known power lift system. It is therefore necessary that the oil in the power lift system is always freshly sucked in.

Es ist bereits ein ölfilter bekannt, bei dem durch Strömungsumkehr eine Filterreinigung bewirkt wird. Dieses ist mit einem Druckspeicher ausgestattet, der unter Einwirkung des Förderdruckes der zu filtrierenden Flüssigkeit aufgeladen wird. Sobald der Förderdruck wegfällt, wird die Strömungsrichtung der Flüssigkeit unter Einwirkung der in dem Windkessel angesammelten Energie umgekehrt und damit eine Reinigung des Filters erzielt. Diese Einrichtung ist besonders geeignet für Anlagen, bei denen die Flüssigkeit drucklos oder mit geringem Druck zurückfließt.An oil filter is already known in which the filter is cleaned by reversing the flow. This is equipped with a pressure accumulator which, under the action of the delivery pressure of the Liquid is charged. As soon as the delivery pressure drops, the direction of flow becomes the Liquid reversed under the action of the energy accumulated in the air chamber and thus a Cleaning the filter achieved. This device is particularly suitable for systems in which the liquid flows back without pressure or at low pressure.

Der Erfindung liegt die Aufgabe zugrunde, eine hydraulische Kraftheberanlage für Ackerschlepper zu schaffen, die einmal mit geringstem Leistungsaufwand betrieben werden kann und andererseits das Ölfilter stets sauber hält.The invention is based on the object of a hydraulic power lift system for agricultural tractors create that can be operated on the one hand with minimal effort and on the other hand the oil filter always keeps it clean.

Die Erfindung besteht bei einer Hydraulikanlage der eingangs genannten Art darin, daß von der Steuereinrichtung eine Rücklaufleitung zum Innern des ölfilters führt und mit den Leitungen zur Pumpe und weiter zur Steuereinrichtung einen geschlossenen Kreislauf bildet.The invention consists in a hydraulic system of the type mentioned in that of the Control device leads a return line to the interior of the oil filter and with the lines to the pump and further forms a closed circuit to the control device.

Dadurch wird mit der Hydraulikanlage nach der Erfindung ein geringerer Leistungsbedarf möglich, da das angesaugte öl den Kreislauf nicht mehr verläßt und nur das zusätzliche Öl in den Kreislauf angesaugt zu werden braucht. Beim Senken des Krafthebers verläßt das überschüssige Öl den Ölfilter und durchströmt dabei diesen in umgekehrter Richtung. Dadurch wird dieser gereinigt, ohne daß eine Strömungsumkehr und dementsprechend ein zusätzlicher Druckspeicher, der zusätzlicher Energie bedarf, nötig wird.As a result, a lower power requirement is possible with the hydraulic system according to the invention, since the sucked oil no longer leaves the circuit and only the additional oil is sucked into the circuit needs to become. When the power lift is lowered, the excess oil leaves the oil filter and flows through this in the opposite direction. This cleans it without reversing the flow and accordingly an additional pressure accumulator, which requires additional energy, is necessary will.

In der Zeichnung ist die Hydraulikanlage nach der Erfindung in einem Ausführungsbeispiel dargestellt, bei dem an das Getriebegehäuse eines Ackerschleppers ein gesonderter Behälter angeflanscht ist.In the drawing, the hydraulic system according to the invention is shown in an exemplary embodiment, in which a separate container is flanged to the gearbox of an agricultural tractor.

In dem Behälter 1, der an das Getriebegehäuse 2 für das Fahrzeuggetriebe angeflanscht ist, befindet sich das Ölfilter 3. An dem Behälter 1 ist die das Drucköl erzeugende Pumpe 4 angeordnet, die mit dem Ölfilter 3 durch die Saugleitung 5 verbunden ist. Von der Pumpe 4 führt die Druckleitung 6 zu einer als Dreiwegehahn ausgebildeten Steuereinrichtung 7, die außerdem durch die Rücklaufleitung 8 mit dem Filter 3 und durch die Leitung 9 mit dem Antriebszylinder 10 verbunden ist. Mittels des Handgriffes 11 kann die Steuereinrichtung 7 in die drei Stellungen »0« (Leerlauf), »S« (Senken) und »H« (Heben) verstellt werden. Die Pumpe 4 wird von der Zapfwelle 12 des Fahrzeuggetriebes angetrieben.In the container 1, which is flanged to the gear housing 2 for the vehicle transmission, the oil filter 3. At is the container 1, the pressurized oil generating pump 4 arranged, which is connected to the oil filter 3 through the suction line. 5 The pressure line 6 leads from the pump 4 to a control device 7 designed as a three-way valve, which is also connected to the filter 3 through the return line 8 and to the drive cylinder 10 through the line 9. By means of the handle 11, the control device 7 can be adjusted to the three positions “0” (idle), “S” (lowering) and “H” (lifting). The pump 4 is driven by the power take-off shaft 12 of the vehicle transmission.
