Abstract

A needle case and a yoke are respectively formed on their surfaces to be joined together with a key and a keyway which are so shaped as to provide a clearance for receiving a wedge of suitable shape. When driven the needle case and the yoke fastened together the wedge tightly holds them together in intimate contact with each other. The key is trapezoidal in cross section and the keyway is in the form of a dovetail groove conforming to the shape of the key and the opposed inside surface of the yoke defining the keyway.

Description

Vorrichtung zur Befestigung einer Nadelbüchse am Joch einesDevice for attaching a needle hub to the yoke of a

Drehzapfen-Kreuzgelenks Die Erfindung betrifft eine Vorrichtung zur Befestigung einer Nadelbüchse am Joch eines Drehzapfen-Kreuzgelenks, bei welcher die Nadelbüchse bzw. das Joch auf ihren zu verbindenden Flächen einen Keil bzw. eine Keilnut zur Aufnahme des Keiles aufweisen und die Nadelbüchse am Joch durch Bolzen festlegbar ist. Trunnion universal joint The invention relates to a device for Attachment of a needle hub to the yoke of a trunnion universal joint, in which the needle sleeve or the yoke on the surfaces to be connected a wedge or have a keyway for receiving the key and the needle sleeve on the yoke through Bolt is fixable.

Bei den bekannten Drehzapfen-Kreuzgelenken dieser Art wird die Gadelbüchse am Joch durch zwei Bolzen festgelegt, wobei ein an der Nadelbüchse angeordneter, einfach geformter Keil in eine identisch geformte Keilnut in der Oberfläche des Jochs eingreift. Bei dieser in den Fig. 1 und 2 dargestellten, bekannten Konstruktion wird das Nadellager A bei der Drehmomentsübertragung einem Verkantungsmornent ausgesetzt, das dem Produkt F-h entspricht, worin F das Drehmoment des Kreuzgelenks und h den Abstand von der Verbindungsfläche zur Mittellinie des Drehzapfens darstellt. Dieses Verkantungsmoment, welches die Nadelbüchse A auf der Verbindungsfläche des nicht dargestellten Jochs zu verkanten sucht, soll nicht durch die Bolzen B, sondern durch den Eingriff des Keiles C mit der nicht dargestellten Keilnut aufgenommen werden. Wenn jedoch zwischen dem Keil C und der Keilnut des Jochs ein Spiel besteht, wirkt auf die Halterungsbolzen B eine Zugspannung P=F.h/(X+Y). Die Bolzen müssen daher eine hinreichende Halterungskraft besitzen um die Nadelbuchse auch während der Drehmomentsübertragung gegen das Verkantungsinoment in enger Berührung mit dem Joch festzulegen1 Aus diesem Grund besteht stets eine Tendenz, Bolzen mit größerem Durchmesser zu benutzen.In the known pivot universal joints of this type, the Gadelbüchse fixed on the yoke by two bolts, one arranged on the needle sleeve, simply shaped key into an identically shaped keyway in the surface of the Yoke engages. In this known construction shown in FIGS If the needle roller bearing A is exposed to a canting torque during the torque transmission, which corresponds to the product F-h, where F is the torque of the universal joint and h den Represents the distance from the mating surface to the centerline of the pivot. This Canting moment, which the needle hub A on the connecting surface of the not Seeks to tilt the yoke shown, should not be through the bolts B, but through the engagement of the key C with the keyway, not shown, are included. However, when there is play between the key C and the keyway of the yoke, it acts a tensile stress P = F.h / (X + Y) on the mounting bolts B. The bolts must therefore have a sufficient holding force around the needle hub even during torque transmission against the canting moment in close contact with the yoke to fix1 For this Reason there is always a tendency to bolt with larger diameter to use.

Das in Fig. 1 dargestellte Kreuzgelenk besitzt einen begrenzten Schwenkdurchmesser Dg, der seinerseits die maximale Breite L der Nadelbüchse A begrenzt. Wenn man dabei versucht, den Durchmesser des Bolzens B ohne Veränderung der Drehmomentkapazität des Kreuzgelenks zu erhöhen, vergrößert sich der Durchmesser d der in Fig. 2 dargestellten Bolzenöffnung, wodurch die Dicken spund H des die Bolzenöffnung bildenden Teiles der Nadelbüchse A auf der Verbindungsfläche entsprechend verringert werden. Dabei besteht die Gefahr, daß die Halterungskraft des Bolzens B und das übertragene Drehmoment zu einer Deformation der Nadelbüchse A führen.The universal joint shown in Fig. 1 has a limited pivot diameter Dg, which in turn limits the maximum width L of the needle hub A. If you are there tries to change the diameter of the bolt B without changing the torque capacity of the universal joint, the diameter d of that shown in FIG. 2 increases Bolt opening, whereby the thicknesses bung H of the part forming the bolt opening the needle hub A can be reduced accordingly on the connecting surface. Included there is a risk that the retaining force of the bolt B and the transmitted torque lead to a deformation of the needle hub A.

Jede Verringerung der Eigensteifigkeit der Nadelbüchse verkurzt jedoch die Lebensdauer des Kreuzgelenks und führt zu Nadelbüchsenrissen. Eine Vergrößerung der Bolzenabmessungen bei gleichzeitiger Beibehaltung einer hinreichend eigensteifen Nadelbüchse kann daher nur durch Verkleinerung des Lagerdurchmessers D1 der Nadelbüchse A erreicht werden, was eine entsFrechende Verringerung des Durchmessers D2 des Drehzapfens und eine Verminderung der Drehmomentskapazität mit sich bringt.However, any reduction in the inherent rigidity of the needle bush is shortened the life of the universal joint and leads to needle-box cracks. An enlargement the bolt dimensions while maintaining a sufficiently rigid Needle bushing can therefore only be achieved by reducing the bearing diameter D1 of the needle bushing A can be achieved, resulting in a corresponding reduction in the diameter D2 of the pivot pin and brings about a decrease in torque capacity.

Aufgabe der Erfindung ist es nun, eine Vorrichtung zur Befestigung einer Nadelbüchse am J o Joch eines Drehzapfen-Kreuzgelenks der eingangs genannten Art zu schaffen, die mit einfachen Mitteln auch bei begrenztem Schwenkdurchmesser ohne Beeinträchtigung der Drehmomentskapazität und der Eigensteifigkeit der Nadelbüchse sowie ohne Vergrößerung des Bolzendurchmessers eine nicht allein von der Halterungskraft der Bolzen abhängige, verbesserte Festlegung der Nadelbüchse am Joch ermöglicht und bei gegebener Drehmomentskapazität einen möglichst kleinen Schwenkdurchmesser und damit eine kompakte Bauweise gestattet.The object of the invention is now to provide a device for fastening a needle sleeve on the yoke of a pivot universal joint of the aforementioned Art to create that with simple means even with a limited swing diameter without impairing the torque capacity and the intrinsic rigidity of the needle bush as well as without increasing the bolt diameter one not only from the holding force the bolt-dependent, improved fixing of the needle sleeve on the yoke enables and the smallest possible swivel diameter for a given torque capacity and thus allows a compact design.

Zur Lösung dieser Aufgabe ist die Vorrichtung der eingangs genannten Art erfindungsgemäß dadurch gekennzeichnet, daß die Keilnut zwischen einer Fläche des Keils und der gegenüberliegenden Innenfläche der Keilnut einen Zwischenraum beläßt und zur Festlegung der Nadelbüchse in am Joch anliegender Stellung ein in den Zwischenraum eintreibbares Keilelement vorgesehen ist.To solve this problem, the device is that mentioned at the beginning Type according to the invention characterized in that the keyway is between a surface of the key and the opposing inner surface of the keyway leaves and in order to fix the needle bushing in a position resting against the yoke the intermediate space is provided which can be driven in wedge element.

Durch das in den Zwisciienraum eingetriebene Keilelement wird eine wirksamere Festlegung der Nadelbüchse am Joch erreicht.The wedge element driven into the intermediate space creates a more effective fixing of the needle bushing on the yoke achieved.

Da die Halterungskraft gegen die in Fig. 2 dargestellte Kraft F.h nicht wie bisher allein von den Bolzen aufgebracht zu werden braucht, kann die Verwendung von Bolzen größeren Durchmessers vermieden werden.Since the holding force against the force shown in Fig. 2 F.h the use can not be applied by the bolts alone, as was previously the case larger diameter bolts can be avoided.
