Description

Die Erfindung bezieht sich auf die Lagerung für ein angetriebenes Fahrzeug­ rad nach dem Oberbegriff des Anspruchs 1.The invention relates to the storage for a powered vehicle rad according to the preamble of claim 1.

Zum Antrieb von Fahrzeugrädern sind die Antriebswellen mit Gelenken des Ra­ des verbunden, die einen Radzapfen aufweisen, auf dem das Rad drehbar gehal­ ten ist. Zwischen dem Gelenk und der Antriebswelle ist zur Sicherung gegen äußere Einflüsse ein Faltenbalg angeordnet, der aus einem flexiblen Material besteht. Aufgrund von axialen Verschiebebewegungen der Antriebswelle während des Fahrbetriebs entsteht ein sogenannter Pumpeneffekt, der den Faltenbalg durch Luftansaugung aber auch durch temperaturbedingte Luftausdehnung auf­ weitet und somit zusätzlich belastet und aus seinem Sitz am Lager und an der Welle reißt.The drive shafts with joints of the Ra are used to drive vehicle wheels of connected, which have a wheel journal on which the wheel is rotatably supported is. Between the joint and the drive shaft is to secure against external influences arranged a bellows made of a flexible material consists. Due to axial displacement movements of the drive shaft during the driving operation creates a so-called pump effect, the bellows due to air intake but also due to temperature-related air expansion expands and thus additionally burdened and from its seat at the warehouse and at the Wave tears.

Aus der DE 30 41 855 C2 ist eine Lagerung für ein angetriebenes Fahrzeugrad bekannt, die über einen Faltenbalg abgedeckt ist. Bei Relativbewegungen der Gelenkwelle kann sich der das Lager umgebende Faltenbalg aufblähen und in seiner festen Anordnung lockern.DE 30 41 855 C2 discloses a bearing for a driven vehicle wheel known, which is covered by a bellows. With relative movements of the The drive shaft can inflate and expand the bellows surrounding the bearing loosen its fixed arrangement.

Aus der FR-OS 22 57 042 ist ein längsverschiebliches Gleichlaufdrehgelenk bekannt, welches in dem einen Wellenzapfen eine koaxiale Bohrung aufweist, die zur Entlüftung des Gelenkraums und somit auch zur Entlüftung des Falgenbalgs dient. Diese Bohrung ist dem anderen Wellenzapfen gegenüberliegend. Es wird durch die Bohrung eine gewisse Entlüftung des Faltenbalgs erzielt, wobei das Problem des Schmierfettverlustes nicht gelöst wird.From FR-OS 22 57 042 is a longitudinally movable constant velocity joint known, which has a coaxial bore in the one shaft journal, which to vent the joint space and thus also to vent the Falgenbalgs serves. This hole is the other shaft journal opposite. There is a certain ventilation of the Bellows achieved, but the problem of grease loss is not solved becomes.

Aus dem DE-GM 84 02 784 ist neben der Problematik der Faltenbalgentlüftung auch das Problem des Schmiermittelverlustes aufgrund der Gelenkrotation aus dem Gelenk bekannt. Die Entlüftung erfolgt bei dieser Ausführung durch eine im Faltenbalg eingebrachte Öffnung nahe der Welle. Durch die Lage dieser Öffnung wird der Schmiermittelaustritt verhindert.DE-GM 84 02 784 describes the problem of bellows ventilation also the problem of lubricant loss due to joint rotation known to the joint. In this version, ventilation is carried out by a opening in the bellows near the shaft. Because of the location  This opening prevents the lubricant from escaping.

Aufgabe der Erfindung ist es, eine Lagerung zu schaffen, die diese Nachteile vermeidet und eine Aufweitung des Faltenbalges vermeidet und gleichzeitig eine Sperrung der Fettabfuhr gewährleistet.The object of the invention is to provide a storage which has these disadvantages avoids and avoids an expansion of the bellows and at the same time a blockage of the fat removal guaranteed.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 sowie durch die weiteren Merkmale der Unteransprüche gelöst.This object is achieved by the characterizing features of Claim 1 and solved by the further features of the subclaims.

Die mit der Erfindung hauptsächlich erzielten Vorteile bestehen darin, daß in einfacher Weise mittels eines im Radzapfen angeordneten Rohres eine Ver­ bindung vom Innenraum des Lagers zur Atmosphäre geschaffen wird. Hierdurch wird das sich im Gelenkraum bildende Luftpolster nach außen geleitet. Dar­ über hinaus ist das Rohr in der Weise freistehend zu den Umfangsflächen des Gelenk-Innenraumes angeordnet, daß das durch Zentrifugalkräfte wegschleu­ dernde Fett aus dem Gelenk nicht über den Radzapfen nach außen austreten kann. Das Fett kann sich aufgrund der Sperrung der Bohrung um das Rohr herum ansammeln und wieder in das Gelenk zurückfließen. The main advantages achieved with the invention are that a Ver in a simple manner by means of a tube arranged in the wheel journal bond from the interior of the warehouse to the atmosphere is created. Hereby the air cushion that forms in the joint space is directed outside. Dar in addition, the tube is freestanding to the peripheral surfaces of the Joint interior arranged that the centrifugal forces Do not let grease come out of the joint through the wheel journal can. The grease can become blocked due to the blocking of the hole around the pipe accumulate and flow back into the joint.  

Das Rohr wird in die meist vorhandene Bohrung des Radzapfens eingepreßt und endet an der Stirnseite des Radzapfens und mündet mit seinem gegenüberlie­ genden freien Ende in eine Erweiterung des Gelenkinnenraums ein.The tube is pressed into the usually existing bore of the wheel journal and ends at the front of the wheel journal and ends with its opposite free end in an expansion of the joint interior.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawing and is described in more detail below.

Es zeigtIt shows

Fig. 1 einen Schnitt durch ein Gelenk mit verbundener Antriebswelle, und Fig. 1 shows a section through a joint with a connected drive shaft, and

Fig. 2 einen Schnitt durch ein Rohr. Fig. 2 shows a section through a tube.

Ein Fahrzeugrad 1 ist auf einem Radzapfen 2 eines Gelenks 3 gehalten, das mit einer Antriebswelle 4 entsprechend verbunden ist. Zwischen der Welle 4 und dem Gelenk 3 ist ein abdeckender Faltenbalg 5 vorgesehen, der das Gelenk 3 nach außen hin dicht abschließt.A vehicle wheel 1 is held on a wheel journal 2 of a joint 3 , which is connected to a drive shaft 4 accordingly. A covering bellows 5 is provided between the shaft 4 and the joint 3 and seals the joint 3 tightly to the outside.

Das Gelenk 3 nimmt die Antriebswelle 4 axial in Pfeilrichtungen 6 verschieb­ lich auf und ist mit dem Radzapfen 2 über ein äußeres Gelenkelement 7 starr verbunden.The joint 3 takes the drive shaft 4 axially displaceable in the arrow directions 6 and is rigidly connected to the wheel journal 2 via an outer joint element 7 .

Der Radzapfen 2 umfaßt eine Durchgangsbohrung 8, in der ein Rohr 9 angepreßt gehalten ist. Dieses Rohr 9 erstreckt sich mit einem Teil seiner Länge in der Bohrung 8 und mündet an der Stirnfläche 10 des Radzapfens 2 mit seiner Öffnung 9a aus. Der andere Teil des Rohres 9 erstreckt sich in einem Frei­ raum 11 des Radzapfens 2, der von einer anschließenden Bohrung 12 größeren Durchmessers als das Rohr 9 gebildet wird. Das freie Ende 13 des Rohres 9 mündet in eine trichterförmige Erweiterung 14 des Radzapfens 2 ein, die dem Gelenk 3 zugerichtet ist.The wheel journal 2 comprises a through hole 8 in which a tube 9 is held pressed. This tube 9 extends with part of its length in the bore 8 and opens at the end face 10 of the wheel journal 2 with its opening 9 a. The other part of the tube 9 extends in a free space 11 of the wheel journal 2 , which is formed by a subsequent bore 12 of larger diameter than the tube 9 . The free end 13 of the tube 9 opens into a funnel-shaped extension 14 of the wheel journal 2 , which is directed towards the joint 3 .

Das Rohr 9 ist vorzugsweise zentrisch des Radzapfens 2 angeordnet und steht der Antriebswelle 4 achsgleich gegenüber. Es ist über die Ebene X-X des Grundes der Erweiterung 14 herausragend angeordnet.The tube 9 is preferably arranged centrally of the wheel journal 2 and faces the drive shaft 4 with the same axis. It is arranged in an outstanding manner above level XX of the bottom of the extension 14 .

Das Rohr 9 ist bis zu seiner Einspannung im Radzapfen 2 beabstandet zu den Umfangsflächen 15 und 16 der Bohrung 12 und der Erweiterung 14 angeordnet. Dies ist erforderlich, damit das vom Gelenk wegdrängende Fett im Fahrbetrieb nicht über die Bohrung 8 im Radzapfen 2 austreten kann. Gleichzeitig soll ein sich bildendes Luftpolster im Balg 5 durch Abführen der Luft über den Kanal 17 des Rohres 9 nach außen ableitbar bzw. auch Luft wieder zuführbar sein. Das sich im Fahrbetrieb in der Bohrung 12 ansammelnde Fett kann auf­ grund der trichterförmigen Erweiterung 14 von der Bohrung 12 aus wieder zum Gelenk 3 zurückfließen.The tube 9 is spaced from its circumferential surfaces 15 and 16 of the bore 12 and the extension 14 until it is clamped in the wheel journal 2 . This is necessary so that the grease pushing away from the joint cannot escape through the bore 8 in the wheel journal 2 during driving operation. At the same time, an air cushion which is formed in the bellows 5 should be able to be discharged to the outside or air may be supplied again by discharging the air via the channel 17 of the tube 9 . The grease that accumulates in the bore 12 during driving operation can flow back to the joint 3 due to the funnel-shaped extension 14 from the bore 12 .
