Ölbehälter, insbesondere für hydrostatischeOil containers, in particular for hydrostatic ones
Lenkanlagen von KraftfahrzeugenSteering systems for motor vehicles
Die Erfindung betrifft einen Ölbehälter nach dem Oberbegriff des Patentanspruches 1.The invention relates to an oil container according to the Preamble of claim 1.
Derartige Ölbehälter haben den Zweck, das in Hydraulikkreisläufen umlaufende Druckmittel zu filtern und zu entlüften und die durch Erwärmung entstehenden Volumenänderungen und Leckverluste auszugleichen.Such oil containers have the purpose in hydraulic circuits to filter and bleed circulating pressure medium and the volume changes caused by heating and compensate for leakage losses.
Ein derartiger Ölbehälter ist beispielsweise aus der Deutschen Offenlegungsschrift 1 611 169 bekannt. Bei diesem Ölbehälter mündet ein Einlaufstutzen am Boden des Behälters innerhalb des Filtereinsatzes, während ein Auslaßstutzen in der außerhalb des Filtereinsatzes liegenden Behälterwand angeordnet ist. Dieser Ölbehälter ist insbesondere für ölhydraulische Lenksysteme vorgesehen.Such an oil container is known from German Offenlegungsschrift 1 611 169, for example. With this one Oil tank opens an inlet port at the bottom of the container inside the filter insert, while an outlet port in the container wall lying outside the filter insert is arranged. This oil tank is particularly suitable for oleohydraulics Steering systems provided.

In besonderen Einbaufällen ist die Verwendung eines Ölbehälters der bekannten Ausführung nicht möglich. Bei hydrostatischen Lenkanlagen von Kraftfahrzeugen ist beispielsweise gesetzlich vorgeschrieben, daß die Lenkbarkeit des Fahrzeugs auch bei einem Ölverlust der Lenkanlage sicher gewährleistet bleibt. Dazu muß die erforderliche ölmenge in bestimmter Zeit aus dem Ölbehälter durch die Zulaufleitung rückgesaugt werden können. Bei dem bekannten ölbehälter kann jedoch nur die Ölmenge angesaugt werden, die sich innerhalb des Filtereinsatzes befindet. Danach wird Luft angesaugt. Diese Ölmenge ist aber für ein sicheres Lenken nicht ausreichend. In special installation cases, the use of an oil tank of the known design is not possible. at hydrostatic steering systems of motor vehicles is, for example, required by law that the steerability of the vehicle is reliably guaranteed even in the event of a loss of oil in the steering system. To do this, the required amount of oil must be in a certain time from the oil tank through the supply line can be sucked back. In the known oil container can However, only the amount of oil that is inside the filter element can be sucked in. Then air is sucked in. However, this amount of oil is not sufficient for safe steering.
Der Erfindung liegt deshalb die Aufgabe zugrunde, einen ölbehälter zu schaffen, mit dem bei einem Ölverlust einer hydrostatischen Lenkanlage eine für die sichere Lenkbarkeit des Fahrzeugs erforderliche ölmenge zur Verfügung gestellt werden kann.The invention is therefore based on the object of creating an oil container with which, in the event of an oil loss, a hydrostatic steering system provided an amount of oil required for the safe steerability of the vehicle can be.
Diese Aufgabe wird durch die im kennzeichnenden Teil des Patentanspruches 1 angeführten Merkmale gelöst. Weitere zweckmäßige Merkmale sind in den■Unteransprüchen angegeben.This object is achieved by the features listed in the characterizing part of claim 1. Further Appropriate features are specified in the ■ subclaims.
Nachstehend wird die Erfindung anhand eines in einer Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with the aid of an exemplary embodiment shown in a drawing.

Der Ölbehälter besteht im wesentlichen aus einem Behältertopf 1 mit einem Deckel 2. Der Behältertopf 1 weist an seinem Boden einen Zulaufanschluß 3 für eine Zulaufleitung 4 und einen Ablaufanschluß 5 für eine Ablaufleitung 6 auf. In dem Behältertopf 1 ist in einem.gewissen Abstand über dem Boden des Behältertopfes 1 ein ringzylinderförmiger auswechselbarer Filtereinsatz 7 angeordnet. Der Filtereinsatz 7 ist von zwei Abdeckungen verschlossen, von denen die untere - mit der Ziffer 8 versehen - dargestellt ist.The oil container essentially consists of a container pot 1 with a lid 2. The container pot 1 has an inlet connection 3 for an inlet line 4 at its bottom and a drain connection 5 for a drain line 6. In the container pot 1 is in a certain distance above the Arranged at the bottom of the container pot 1 is an annular cylinder-shaped replaceable filter insert 7. The filter element 7 is closed by two covers, of which the lower one - marked with the number 8 - is shown.
Die Zulaufleitung 4 mündet in den Innenraum 9 des Filtereinsatzes 7. An der Zulaufleitung 4 ist eine Rücksaugeinrichtung 10 angeordnet, die in der Form eines ringförmigen Plattenventils die Zulaufleitung 4 umgibt. Das Plattenventil besteht aus einem Ventiltopf 11, der von einer ersten ringförmigen Ventilplatte 12 abgedeckt wird. Die erste Ventilplatte 12 wirkt mit dem Ventiltopf 11 in bekannter Weise als Überdruckventil. Die erste Ventilplatte 12 weist Bohrungen auf, die durch eine zweite ringförmige Ventilplatte 14 unter der Kraft einer Druckfeder 15 verschlossen sind. Die Druckfeder 15 wirkt eine derart geringe Kraft auf die zweite Ventilplatte. 14 aus, daß diese bereits-bei einem geringen Unterdruck in der Zulaufleitung 4 ein Ansaugen von Öl ausThe inlet line 4 opens into the interior 9 of the filter insert 7. On the inlet line 4 is a back suction device 10 arranged, which surrounds the feed line 4 in the form of an annular plate valve. The plate valve consists of a valve pot 11, which is of a first ring-shaped Valve plate 12 is covered. The first valve plate 12 acts with the valve pot 11 in a known manner as Pressure relief valve. The first valve plate 12 has bores through a second annular valve plate 14 below the force of a compression spring 15 are closed. The compression spring 15 acts such a small force on the second Valve plate. 14 from that this already-at a low Negative pressure in the feed line 4 causes oil to be sucked in

dem Inneren des Behältertopfes 1 über die Bohrungen 13 in einen aus dem Ventiltopf 11 und den beiden Ventilplatten und 14 gebildeten Ringraum 16 ermöglicht. Der Ringraum 16 steht über vorzugsweise radial angeordnete Bohrungen 17 mit dem Inneren der Zulaufleitung 4 in Verbindung.the inside of the container pot 1 via the holes 13 in an annular space 16 formed from the valve pot 11 and the two valve plates 14 and 14 enables. The annulus 16 is in connection with the interior of the feed line 4 via preferably radially arranged bores 17.
Die Abflußleitung 6 weist ein in das Innere des Behältertopfes 1 hineinragendes Leitungsstück 18 auf/ das mit Ab-flußbohrungen 19 versehen ist. Die Abflußbohrungen 19 liegen an der oberen Grenze des Niveaus einer Ölmenge, die bei einem Ölverlust in der Lenkanlage für eine sichere Lenkbarkeit des Fahrzeuges erforderlich ist.The drain line 6 has a line piece 18 protruding into the interior of the container pot 1 / that with drain bores 19 is provided. The drain holes 19 are at the upper limit of the level of an amount of oil that an oil loss in the steering system is necessary for safe steerability of the vehicle.
Bei einem Ölverlust, der beispielsweise durch eine Leckstelle in der Druckleitung der Pumpe entsteht, sinkt das ölniveau nur bis zu den Abflußbohrungen 19, so daß unterhalb dieser Bohrungen noch eine ausreichende ölmenge zur Verfügung steht. Diese ölmenge kann durch eine Steuerpumpe der hydrostatischen Lenkung über die Rücksaugeinrichtung 10 angesaugt werden.If there is a loss of oil, for example due to a leak in the pressure line of the pump, this will decrease oil level only up to the drain holes 19, so that a sufficient amount of oil is still available below these holes. This amount of oil can be controlled by a control pump of the hydrostatic steering are sucked in via the suction device 10.
