Description
Die Erfindung betrifft eine Gelenkwelle, insbesondere zur Verwendung als Seitenwelle in einem Kraftfahrzeug, mit zumindest einem Kugelgleichlauffestgelenk in Form eines Gegenbahngelenkes. Dieses Gegenbahngelenk umfaßt ein Gelenkaußenteil mit Außenbahnen, ein Gelenkinnenteil mit Innenbahnen, drehmomentübertragende Kugeln, die in Bahnpaaren aus Außenbahnen und Innenbahnen aufgenommen sind, und einen Kugelkäfig mit Käfig fenstern, in denen die Kugeln in einer gemeinsamen Ebene gehalten sind und bei Gelenkbeugung auf die winkelhalbierende Ebene geführt werden, erste Außenbahnen bilden mit ersten Innenbahnen erste Bahnpaare, deren Bahnen sich in einer ersten axialen Richtung zur Anschlußseite des Gelenkinnenteils voneinander entfernen und in denen erste Kugeln gehalten sind, zweite Außenbahnen bilden mit zweiten Innenbahnen zweite Bahnpaare, deren Bahnen sich in einer zweiten axialen Richtung zur Anschlußseite des Gelenkaußenteils voneinander entfernen und in denen zweite Kugeln gehalten sind.The invention relates to a propeller shaft, in particular for use as a side shaft in a motor vehicle, with at least one ball constant velocity fixed joint in the form of a counter track joint. This counter-track joint comprises an outer joint part with outer webs, an inner joint part with inner webs, torque-transmitting balls, which are received in pairs of tracks and inner raceways, and a cage with cage cage, in which the balls are held in a common plane and articulated to the bisecting plane are guided, first outer webs form with first inner webs first pairs of tracks whose tracks are in a first axial direction to the connection side of the inner joint part from each other and in which first balls are held, second outer tracks form with second inner webs second pairs of tracks whose tracks are in a second axial Remove direction to the connection side of the outer joint part from each other and in which second balls are held.
Gegenbahngelenke der vorstehend genannten Art haben den Vorteil, daß auf die über dem Umfang abwechseln in ersten Bahnpaaren und zweiten Bahnpaaren angeordneten Kugeln von den Bahnen jeweils abwechseln in eine erste Richtung und in eine zweite Richtung weisende Kräfte ausgeübt werden. Diese Kräfte werden von Gegenkräften des Kugelkäfigs aufgefangen, die als innere Kräfte im Gleichgewicht sind, so daß auf den Käfig keine äußeren Axialkräfte ausgeübt werden. Der Käfig läuft damit relativ reibungsfrei gegenüber dem Gelenkaußenteil. Bisher ist es aus Fertigungs- und Montagegründen und in Bezug auf die bevorzugten Kugelgrößen bei Gelenken nach dem Stand der Technik üblich, daß jeweils einem ersten sich in einer ersten Richtung öffnendem Bahnenpaar ein zweites sich in einer zweiten Richtung öffnendes Bahnenpaar radial gegenüberliegt, wobei insbesondere sechs Bahnpaare vorhanden sind. Dies hat schwerwiegende Nachteile für die Gelenksteuerung, nämlich die Steuerungskraftverhältnisse am Käfig. Eine einwandfreie Steuerung des Käfigs ist jedoch erforderlich, um jederzeit bei Gelenkbeugung die Gesamtheit der Kugeln mit ausreichenden Steuerungskräften auf die winkelhalbierende Ebene zu führen, die den Winkel zwischen den Achsen von Gelenkaußenteil und Gelenkinnenteil symmetrisch teilt. Die Grunde für diese nachteilige Steuerung bei Gelenken nach dem Stand der Technik werden anhand der Zeichnungen später näher erläutert.Counter-track joints of the aforementioned type have the advantage that alternately arranged in the first and second direction in a first direction in a second direction forces are exerted on the alternating over the circumference in first pairs of tracks and second pairs of tracks balls of the tracks. These forces are absorbed by opposing forces of the ball cage, which are in balance as internal forces, so that no external axial forces are exerted on the cage. The cage thus runs relatively frictionless against the outer joint part. So far, it is common for manufacturing and assembly reasons and with respect to the preferred ball sizes in joints according to the prior art, that in each case a first opening in a first direction pair of webs a second opening in a second direction pair of webs radially opposite, in particular six Railway pairs are available. This has serious disadvantages for the joint control, namely the control force ratios on the cage. However, proper control of the cage is required to guide the entirety of the balls with sufficient control forces to the bisecting plane at any time during articulation bending, which symmetrically divides the angle between the axes of the outer joint part and the inner joint part. The reasons for this disadvantageous control in joints according to the prior art will be explained in more detail with reference to the drawings.

Hiervon ausgehend ist es Aufgabe der vorliegenden Erfindung, eine Gelenkwelle der eingangs genannten Art mit einem Gegenbahngelenk mit verbesserten Steuereigenschaften bereitzustellen. Die Lösung hierfür besteht darin, daß in dem genannten Gelenk erste Bahnpaare jeweils ersten Bahnpaaren radial gegenüberliegen und zweite Bahnpaare jeweils zweiten Bahnpaaren radial gegenüberliegen wobei erste Bahnpaare und zweite Bahnpaare über dem Umfang abwechselnd angeordnet sind. Es wird ein Gelenk mit acht gleichmäßig umfangsverteilten Bahnpaaren vorgeschlagen, wobei der Kugelkäfig eine sphärischen Außenfläche hat, die in einer sphärischen Innenfläche des Gelenkaußenteils gehalten ist, wobei die sphärische Innenfläche einen Verlauf in Richtung einer Achse des Gelenkaußenteils hat, wobei die sphärische Innenfläche entlang des Verlaufs beidseits der Mittelebene des Gelenkes einander gegenüberliegende Käfigabstützflächen aufweist. Andere Möglichkeiten liegen in der Auswahl von zwölf oder sechszehn Bahnpaaren. Eine erfindungsgemäße Gelenkwelle mit einem solchen Gelenk zeichnet sich durch eine deutlich verbesserte Haltbarkeit des Gelenks aus, das insbesondere als getriebeseitiges Gelenk in einer aus zwei Festgelenken und einer Zwischenwelle mit integrierter Axialverschiebeeinheit bestehenden Gelenkwelle eingesetzt wird. Dabei wird das Gelenkaußenteil vom Differentialgetriebe angetrieben und das Gelenkinnenteil ist mit der Zwischenwelle verbunden. Die verbesserte Haltbarkeit beruht auf im abgebeugten Zustand dauernd von null verschiedene resultierende Steuerungskräften, die von Bahnpaaren auf jeweils sich gegenüberliegende Kugelpaare ausgeübt werden, so daß insgesamt die Käfigsteuerung wesentlich verbessert wird. Die Begründung für diese verbesserte Steuerungskraftverhältnisse werden anhand der Zeichnungen erläutert.On this basis, it is an object of the present invention to provide a PTO shaft of the aforementioned type with a counter track joint with improved control properties. The solution to this is that in the said joint first pairs of tracks each radially opposite first pair of tracks and second pairs of tracks respectively radially opposite second pairs of tracks wherein first pairs of tracks and second pairs of tracks are arranged alternately over the circumference. It is proposed a joint with eight equally circumferentially distributed track pairs, wherein the ball cage has a spherical outer surface held in a spherical inner surface of the outer joint part, wherein the spherical inner surface has a course in the direction of an axis of the outer joint part, wherein the spherical inner surface along the course on both sides of the median plane of the joint has opposite Käfigabstützflächen. Other options include the choice of twelve or sixteen pairs of tracks. A propeller shaft according to the invention with such a joint is characterized by a significantly improved durability of the joint, which is used in particular as a transmission-side joint in a drive shaft consisting of two fixed joints and an intermediate shaft with integrated axial displacement. The outer joint part is driven by the differential gear and the inner joint part is connected to the intermediate shaft. The improved durability is due to non-zero, non-zero resulting control forces exerted by track pairs on respective opposing pairs of balls so that overall the cage control is substantially improved. The justification for these improved control force relationships will be explained with reference to the drawings.
