Abstract
Description
Die Erfindung betrifft einen Ölbehälter für ein hydraulisches System, insbesondere für ein Lenksystem nach dem Oberbegriff des Anspruch 1.The invention relates to an oil tank for a hydraulic System, especially for a steering system according to the preamble of claim 1.
Ölbehälter für hydraulische
Systeme, wie etwa hydraulisch unterstützte Lenksysteme, sind bekannt (
Das Behältergehäuse solcher Ölbehälter weist einen Ölzulauf und einen Ölablauf auf, wobei durch den Ölzulauf ein häufig mit Gasblasen beladener Ölstrom in den Ölbehälter geführt ist.The container housing of such oil containers has an oil supply and an oil drain on, through the oil supply one often Oil stream loaded with gas bubbles is led into the oil tank.
Werden solche Gasblasen durch den Ölablauf einer Pumpe des hydraulischen Systems zugeführt, wird die Ölströmung in der Pumpe gestört. Es kann zudem zu unerwünschten Geräuschemissionen durch schlagartiges Zusammenbrechen der Gasblasen und zu Kavitation in der Pumpe kommen.Such gas bubbles are caused by the oil drain A pump of the hydraulic system is fed, the oil flow in the pump disrupted. It can also become undesirable noise emissions by sudden collapse of the gas bubbles and cavitation come in the pump.
Der Erfindung liegt die Aufgabe zugrunde, einen gattungsgemäßen Ölbehälter so weiterzubilden, dass Öl ohne gasförmige Einschlüsse dem Ölablauf des Ölbehälters entnommen werden kann.The invention is based on the object a generic oil container like this train that oil without gaseous inclusions the oil drain removed from the oil tank can be.
Die Aufgabe wird mit einem Ölbehälter mit den Merkmalen des Anspruchs 1 gelöst.The task comes with an oil container solved the features of claim 1.
Dadurch, dass in dem Ölbehälter stromab dessen Ölzulaufes der Ölstrom durch einen, diesen mehrfach umlenken, labyrinthartigen Strömungskanal gelenkt wird, wobei der labyrinthartige Strömungskanal räumlich von dem Ölbehälterinnenraum getrennt ist, ist bewirkt, dass mit ungelösten Gasblasen beladenes, in den Ölbehälter, insbesondere von einer Abspritzbohrung eines Druckbegrenzungsventils einströmendes Öl sich beruhigen kann und das Öl in dem Ölbehälter nicht aufschäumt. Gasblasen können vom Ölstrom getrennt werden und gelangen nicht in Öl im Ölbehälterinnenraum.Because in the oil tank downstream whose oil supply the oil flow through a labyrinth-like flow channel that redirects it several times is steered, the labyrinthine flow channel spatially from the oil tank interior is separated, is caused to cause undissolved gas bubbles in the oil container, in particular Calm down oil flowing in from a pressure relief valve injection bore can and the oil not in the oil container foams. Gas bubbles can from the oil flow be separated and do not get into oil in the oil tank interior.
Es kann zweckmäßig sein, den labyrinthartigen Strömungskanal zusammen mit einem Filter in dem Ölbehälter als Baueinheit auszubilden, vorzugsweise einstöckig etwa aus Kunststoff mit diesem zu bilden. Die Baueinheit aus labyrinthartigem Strömungskanal und Filter wird zweckmäßig so gestaltet, dass sie in bevorzugt axialer Richtung des Ölbehälters eingeschoben werden kann und sich radial an dem Behältergehäuse abstützt.It may be appropriate to use the labyrinthine flow channel together with a filter in the oil tank as a structural unit, preferably one-story about to form plastic with this. The assembly of labyrinthine Flow channel and Filter is designed appropriately so that it can be inserted in the preferred axial direction of the oil container and is supported radially on the container housing.
Öl mit ungelösten Gasblasen fließt insbesondere aus Abspritzbohrungen von Druckbegrenzungsventilen solcher hydraulischer Systeme, wodurch es zweckmäßig ist, eine Abspritzbohrung eines Druckbegrenzungsventils fluidisch mit einem erfindungsgemäßen labyrinthartigen Strömungskanal zu verbinden.oil with unsolved Gas bubbles are flowing especially from spray bores of pressure relief valves such hydraulic systems, which makes it useful to have a spray hole of a pressure relief valve fluidically with a labyrinthine according to the invention flow channel connect to.
Um Gasblasen in dem Ölstrom des labyrinthartigen Strömungskanals sicher vor dem Wiedereintritt in die Ölfüllung des Ölbehälters zu hindern, ist ein Ölaustritt, der auch als eine einzige Ölaustrittsöffnung des labyrinthartigen Strömungskanals ausgebildet sein kann, bevorzugt in einem oberen topographischen Bereich des Ölbehälters anzuordnen. Auf diese Weise lassen sich Gasblasen vom Öl trennen und eine annährend gasfreie Ölfüllung des Ölbehälters ist dadurch bewirkt.To gas bubbles in the oil flow of the labyrinthine flow channel preventing oil from re-entering the oil tank is an oil leak, which also functions as a single oil outlet of the labyrinthine flow channel can be formed, preferably in an upper topographic Arrange the area of the oil tank. In this way, gas bubbles can be separated from the oil and the oil tank is almost gas-free thereby.
Der labyrinthartige Strömungskanal kann durch Anordnung von Trennwänden in einem kastenförmigen Hohlraum oder durch einen, den Ölstrom mehrfach umlenkenden, in dem Ölbehälter angeordneten Schlauch gebildet sein.The labyrinthine flow channel can by arranging partitions in a box-shaped Cavity or through one, the oil flow multiple deflecting hose arranged in the oil container be educated.
Um die Höhe des Ölbehälters gering zu halten, kann es zweckmäßig sein, den labyrinthartigen Strömungskanal zwischen dem Filter und der Ölbehälterwand anzuordnen. Dies kann bevorzugt so erfolgen, dass der labyrinthartige Strömungskanal sich etwa um ¼ des Ölbehälter-Umfanges und bevorzugt über zumindest 2/3 der axialen Länge oder Höhe des Ölbehälters erstreckt. Der labyrinthartige Strömungskanal ist dabei in einem kreisbogenförmigen Kasten angeordnet. Ein etwa in dem Ölbehälter unterzubringendes Druckbegrenzungsventil kann, in radialer Richtung des Ölbehälters betrachtet, zwischen dem Ölbehälterinnenraum und dem labyrinthartigen Strömungskanal angeordnet sein.To keep the height of the oil tank low, you can it be appropriate the labyrinthine flow channel between the filter and the oil tank wall to arrange. This can preferably be done so that the labyrinthine flow channel about ¼ of the circumference of the oil container and preferably over at least 2/3 of the axial length or height of the oil tank extends. The labyrinthine flow channel is in a circular arc Box arranged. A pressure relief valve to be accommodated in the oil tank, for example can, viewed in the radial direction of the oil container, between the oil tank interior and the labyrinthine flow channel be arranged.
