Abstract
Description
Die Erfindung betrifft ein Zapfenkreuz eines Kreuzgelenks, umfassend einen Grundkörper, von dem aus sich vier Zapfen erstrecken, wobei jeder Zapfen einen zylindrischen Abschnitt aufweist, der einen Durchmesser und eine Länge in Achsrichtung des Zapfens aufweist.The invention relates to a spider of a universal joint, comprising a base body, from which four pins extend, wherein each pin has a cylindrical portion having a diameter and a length in the axial direction of the pin.
Im Stand der Technik sind Kreuzgelenke hinlänglich bekannt, deren zentraler Bestandteil ein Zapfenkreuz der genannten Art ist. Das Zapfenkreuz weist vier Zapfen mit einer zylindrischen Oberfläche auf, die an einem Grundkörper angeformt sind und die für die Aufnahme eines Lagers vorgesehen sind. Hierbei können sowohl Wälzlager (bevorzugt Nadelhülsen) als auch Gleitlager zum Einsatz kommen. Das Zapfenkreuz ist dabei als Massivteil ausgebildet, wobei gegebenenfalls kleine Zentrierbohrungen oder kleine Bohrungen zwecks Zuleitung von Schmiermittel im Bereich des zylindrischen Abschnitts eingebracht sein können. In the prior art universal joints are well known, the central part is a spider of the type mentioned. The spider has four pins with a cylindrical surface, which are integrally formed on a base body and which are provided for receiving a bearing. In this case, both rolling bearings (preferably needle sleeves) and plain bearings can be used. The journal cross is formed as a solid part, with possibly small centering holes or small holes for the purpose of supplying lubricant in the region of the cylindrical portion may be introduced.
Es hat sich gezeigt, dass die an sich angestrebte massive Ausbildung des Zapfenkreuzes und insbesondere der zylindrischen Abschnitte auch Nachteile haben kann. Hier ist zu nennen, dass die Anpassungsfähigkeit des zylindrischen Abschnitts bei verformungsbedingten Abweichungen von der Idelform kaum gegeben ist, so dass es im gegebenen Fall zu einem Kantentragen bei den Lagerungen kommen kann. Bei der Drehmomentübertragung entsteht am Ende des zylindrischen Abschnitts eines Zapfens eine Kontaktspannungsüberhöhung. It has been shown that the desired in itself massive training of the spider and in particular the cylindrical sections can also have disadvantages. Here it should be mentioned that the adaptability of the cylindrical portion is hardly given deformation-related deviations from the ideal shape, so that in the given case can lead to an edge support in the bearings. During torque transmission, a contact voltage increase occurs at the end of the cylindrical section of a pin.
Des weiteren hat auch das sich ergebende Gewicht eine nachteilige Wirkung, insbesondere im Falle der Anwendung im Fahrzeugbereich (sowohl bei der Anwendung im PKW als auch im LKW).Furthermore, the resulting weight has an adverse effect, especially in the case of application in the vehicle sector (both in the car and in the truck).
Der Erfindung liegt die Aufgabe zugrunde, ein gattungsgemäßes Zapfenkreuz so fortzubilden, dass sich in einfacher Weise eine bessere Anpassbarkeit des Bauteils bei lastbedingten Verformungen ergibt. Ferner soll das Bauteil leichter aufgeführt werden, ohne die Festigkeit des Materials zu beeinträchtigen.The invention has the object of providing a generic cross member so educate that results in a simple way better adaptability of the component under load-induced deformations. Furthermore, the component should be listed more easily, without affecting the strength of the material.
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass zumindest einer der Zapfen in seinem Inneren mit einer Ausnehmung versehen ist, die mindestens 25 % des Volumens des zylindrischen Abschnitts beträgt. Bevorzugt beträgt die Ausnehmung mindestens 40 % des Volumens des zylindrischen Abschnitts.The solution of this object by the invention is characterized in that at least one of the pins is provided in its interior with a recess which amounts to at least 25% of the volume of the cylindrical portion. Preferably, the recess is at least 40% of the volume of the cylindrical portion.
Dabei ist vorzugsweise jeder der Zapfen mit einer Ausnehmung versehen. Die Ausnehmung weist bevorzugt zumindest abschnittsweise eine zylindrische Ausformung auf, wobei die Achse der zylindrischen Ausformung die Achsrichtung des Zapfens ist. In this case, each of the pins is preferably provided with a recess. The recess preferably has at least sections on a cylindrical shape, wherein the axis of the cylindrical shape is the axial direction of the pin.
Die Ausnehmung kann dabei als Sackloch ausgeführt sein. Das Sackloch ist bevorzugt an seinem Ende kegelförmig ausgebildet; alternativ kann aber auch eine halbkugelförmige oder halbellipsoide Ausgestaltung gewählt werden. The recess can be designed as a blind hole. The blind hole is preferably formed conically at its end; Alternatively, however, a hemispherical or halbellipsoide design can be selected.
Alternativ kann vorgesehen sein, dass die Ausnehmung das Zapfenkreuz vollständig durchsetzt. Alternatively it can be provided that the recess completely passes through the spider.
Das Zapfenkreuz ist bevorzugt als einstückiges Massivteil ausgeführt. Es ist bevorzugt Bestandteil einer Gelenkwelle eines Fahrzeugs. Weitere Anwendungen sind Kreuzgelenkbüchsen verschiedener Art.The spider is preferably designed as a one-piece solid part. It is preferably part of a propeller shaft of a vehicle. Further applications are universal joint bushes of various types.
Das erfindungsgemäße Konzept stellt also darauf ab, dass der zylindrische Abschnitt eines Zapfens des Zapfenkreuzes gezielt in seinem Inneren mit einem Hohlraum versehen ist. The concept according to the invention thus depends on the fact that the cylindrical portion of a pin of the spider is specifically provided with a cavity in its interior.
Bei entsprechender Ausgestaltung desselben nimmt die erforderliche Festigkeit des Bauteils nur unwesentlich ab, während gleichzeitig eine wesentlich bessere Anpassungsfähigkeit an Verformungen möglich ist. Hiermit kann gegebenenfalls ein Kantentragen bei der Lagerung vermieden werden. Der lokale Kontaktduck kann so abgebaut werden.With a corresponding embodiment of the same, the required strength of the component decreases only slightly, while at the same time a much better adaptability to deformations is possible. This can possibly be an edge support during storage can be avoided. The local contact pressure can thus be reduced.
Ferner wird das Zapfenkreuz wesentlich leichter, was entsprechende Vorteile hat, insbesondere im Falle der Anwendung bei Kraftfahrzeugen. Hier ist insbesondere die Gelenkwelle betroffen, die insgesamt ein nicht unerhebliches Gewicht hat. Ein besonders bevorzugter Anwendungsfall sind Gelenkwellen von Nutzfahrzeugen, da hier die Zapfenkreuze oft überdimensioniert sind.Furthermore, the cross member is much easier, which has corresponding advantages, especially in the case of application in motor vehicles. Here, in particular, the PTO shaft is affected, which has a total of considerable weight. A particularly preferred application are cardan shafts of commercial vehicles, since here the spigots are often oversized.
Der erfindungsgemäße Vorschlag kann natürlich aber auch in anderen Fällen eingesetzt werden. Generell sind Anwendungen in der Industrie und im Bereich von Eisenbahnen genauso möglich und sinnvoll.Of course, the proposal according to the invention can also be used in other cases. In general, applications in the industry and in the area of railways are just as possible and meaningful.
Sehr vorteilhaft ist also neben dem geringeren Gewicht des Zapfenkreuzes eine höhere Flexibilität am Ende des Kreuzzapfens, wo die höchsten Kontaktspannungen durch verformungsbedingte Schiefstellung während des Betriebs entstehen. Eine höhere Flexibilität des Zapfenendbereiches kann die Spannungen im Wälzkörperkontakt minimieren und so zu einer längeren Lebensdauer beitragen.Very advantageous is in addition to the lower weight of the spider a higher flexibility at the end of the cross pin, where the highest contact stresses caused by deformation-induced misalignment during operation. Higher flexibility of the journal end area can minimize the stresses in the rolling element contact and thus contribute to a longer service life.
Weiterhin kann auch Material eingespart werden, was zu entsprechenden Kostenvorteilen führt.Furthermore, material can also be saved, which leads to corresponding cost advantages.
