Description
Abdichtung für ein Gleichlaufgelenk, insbesondere für Kraftfahrzeuge Die Erfindung betrifft eine Abdichtung für Gelenke, vorzugsweise für Gelenke mit konstruktiv begrenzten Einbauverhältnissen, z.B. Schubkugelgelenke für Kraftfahrzeuge und vornehmlich für Gleichlaufgelenke, mit Kugeln zur Drehmomentübertragung, die in entsprechenden. acheparallelen Bahnen oder Gelenkteilen geführt und in einem Käfig angeordnet sind, der zwangsläufig auf die Winkelhalbierende des Gelenks einstellbar ist, durch einen Steuerhebel, der insbesondere im Käfig selbst axial unverschiebbar, in beiden Gelenkteilen zentral dagegen axial verschiebbar geführt ist.Seal for a constant velocity joint, in particular for motor vehicles The invention relates to a seal for joints, preferably for joints with Constructively limited installation space, e.g. thrust ball joints for motor vehicles and mainly for constant velocity joints, with balls for torque transmission, the in appropriate. axially parallel tracks or joint parts out and in one Cage are arranged, which is inevitably adjustable to the bisector of the joint is, by means of a control lever, which is axially immovable in the cage itself, In contrast, is guided axially displaceably centrally in both joint parts.
Gelenke der vorstehend erwähnten Art sind insbesondere für die Ubertragung großer Drehmomente, sowie für höhere Drehzahlen und greß..e Beugungswinkel vorgesehen. Hierbei ist eine besonders gute Schmierung erforderlich. Das Gelenk muß daher gut abgedichtet werden, und zwar zweckmäßig am Gelenk selbst.Joints of the type mentioned above are particularly useful for transmission large torques, as well as for higher speeds and large deflection angles. Particularly good lubrication is required here. The joint must therefore be good be sealed, expediently at the joint itself.
Der Erfindung liegen die oben genannten Probleme als Aufgabe zugrunde. Sie löst diese Aufgabe bei den eingangs genannten Gelenken dadurch, daß an dem einen der beiden Gelenkteile ein Dichtring aus elastischem lateral angeordnet ist, der mit einer auswärts gekehrten Dichtlippe innen an einer dem anderen Gelenkteil zugeordneten Kugelkalotte anliegt.The invention is based on the above-mentioned problems. It solves this problem in the joints mentioned above in that on one of the two joint parts, a sealing ring made of elastic is arranged laterally, the with an outwardly facing sealing lip on the inside of one associated with the other joint part Spherical cap rests.
Die erfindungsgemäße Abdichtung läuft synchron mit dem Gelenk um, sodaß Panschverluste vermieden werden. Die Dichtlippe wird durch die Fliehkraft in erhöhtem Maß an die Kugelkalotte des anderen Teils angedrückt. Je höher die Drehzahl wird, umsomehr erhöht sich daher der Anlagedruck der Dichtlippe.The seal according to the invention runs synchronously with the joint, so that splash losses are avoided. The sealing lip is made by centrifugal force to a greater extent to the spherical cap of the pressed on the other part. The higher the speed, the more the contact pressure of the sealing lip increases.
Bei einer Ausführung;sform nach der Erfindung erstreckt sich der Dichtring im wesentlichen axial und an seinem einen Rand ist er für die Befestigung in an sich bekannter Weise mit einem Metall- oder Kunststoffring festhaftend verbunden, während am anderen Rand die Dichtlippe angeordnet ist.In one embodiment according to the invention, the sealing ring extends essentially axially and at one edge it is for attachment to firmly attached to a metal or plastic ring in a known manner, while the sealing lip is arranged on the other edge.
Im Grunde genommen kann der Dichtring sowohl am äußeren wie am inneren Gelenkteil befestigt sein. Die l.rfindung bevorzugt aber eine Lösung, wonach an dem äußeren Gelenkteil der Dichtring und am inneren Gelenkteil die Kugelkalotte angeordnet ist. Auf diese Weise läßt sich ein leichteres vintauchen bei der Beugung des Gelenks erzielen. Im einzelnen schlägt die Erfindung hierfür vor, daß der Dichtring mittels eines im Querschnitt winkelförmigen, festen Ringes auf den äußeren Gelenkteil aufgeschoben ist und daß seine Dichtlippe an einem als Blechpreßteil ausgebildeten und auf den inneren Gelenkteil aufgeschobenen Kalottenteil anliegt.Basically, the sealing ring can be used on both the outer and the inner Joint part be attached. The l.rfindung prefers a solution, according to which the outer joint part of the sealing ring and on the inner joint part the spherical cap is arranged. In this way, it is easier to immerse yourself in the flexion of the joint. In detail, the invention proposes that the sealing ring by means of a fixed ring with an angular cross-section on the outer joint part is pushed and that its sealing lip is formed on a pressed sheet metal part and the cap part pushed onto the inner joint part rests.
Einzelheiten der Erfindung zeigt das Ausführungsbeispiel der Zeichnung anhand eines Längsschnittes durch eine derartige Dichtungsanordnung.Details of the invention are shown in the exemplary embodiment in the drawing based on a longitudinal section through such a sealing arrangement.
IJach der Zeichnung ist das Gelenk 10 innerhalb eines nicht näher dargestellten, sogenannten Schubkugelgelenks 11 am Kraftfahrzeug angeordnet. Das Gelenk 10 besteht aus dem inneren Gelenkteil 12 und dem äußeren Gelenkteil 13, wobei das erstere mit dem Antriebsmotor und das letztere mit der Kardanwelle verbunden ist. Beide Gelenkteile 12 und 13 weisen achsparallele Kugelbahnen 14 und 15 auf, in denen Kugeln 16 zur Drehmomentübertragung angeordnet sind. Diese Kugeln werden durch einen nicht largestellten Käfig zwangsläufig auf die Winkelhalbierende cleo Peugungswinkels eingestellt.According to the drawing, the joint 10 is not closer within one shown, so-called thrust ball joint 11 arranged on the motor vehicle. That Joint 10 consists of the inner joint part 12 and the outer joint part 13, wherein the former connected to the drive motor and the latter to the cardan shaft is. Both joint parts 12 and 13 have axially parallel ball tracks 14 and 15, in which balls 16 are arranged for torque transmission. These balls will inevitably to the bisector cleo due to a non-positioned cage Peugungswinkel adjusted.
Für die Abdichtung des Gelenks ist ein Dichtring 17 auf den äußeren Gelenkteil 13 aufgesc'ioben. Der Dichtring 17 besteht aus einem sich im wesentlichen axial erstreckenden, elastischen Ringkörper 18, der auf der einen Seite mit einem im Querschnitt winkelförmigen Metall-t oder Kunststoffring 19 festhaftend verbundeh-ist. Am anderen Ende bildet der elastische Ringkörper 18 eine Dichtlippe 20, die von innen an einer Kugelkalotte 21 anliegt, welche mit einem Roiirstutzen 22 auf den inneren Gelenkteil 12 aufgeschoben ist. diese Kalotte 21 übergreift bei der Beugung des Gelenks den äußeren Gelenkteil 13. Die Verformungen des Dichtringes 17 bei :nr Beugung und bei evntueller Axialverschiebung des Gelenks werden durch seinen elastischen Ringkörper 18 aufgenommen, der unter Umständen hierfür noch eine etwas größere axiale Erstreckung aufweisen kann.To seal the joint, a sealing ring 17 is on the outer Joint part 13 aufgesc'ioben. The sealing ring 17 consists of a substantially axially extending, elastic ring body 18, which on one side with a Angled metal-t or plastic ring 19 in cross-section is firmly bonded. At the other end of the elastic ring body 18 forms a sealing lip 20, which of rests on the inside of a spherical cap 21, which with a Roiirstutzen 22 on the inner joint part 12 is pushed. this dome 21 overlaps when it is bent of the joint the outer joint part 13. The deformations of the sealing ring 17 at: no Flexion and possible axial displacement of the joint are made possible by its elastic Annular body 18 added, which may also have a slightly larger axial May have extension.
