Description

Die Erfindung bezieht sich auf die Lagerung der Gelenkzapfen von Kreuzgelenken für Kraftfahrzeuge.The invention relates to the mounting of the pivot pins of universal joints for automobiles.

Es ist bekannt, die Gelenkzapfen von Kreuzgelenken in Nadellagern zu lagern, :die zur Aufnahme stoßender und rüttelnder Bewegungen besonders geeignet sind. In den Kreuzgelenken von Kraftfahrzeugen sind die Lagernadeln jedoch häufig Kantenpressungen ausgesetzt, die einen verhältnismäßig schnellen Verschleiß der Nadeln und Laufflächen der Zapfenlagerung zur Folge haben. Auf Grund der Erfindung wird dieser Mangel behoben.It is known that the pivot pins of universal joints in needle bearings to store: those particularly suitable for absorbing jerking and shaking movements are. However, bearing needles are common in the universal joints of motor vehicles Exposed to edge pressures that cause relatively rapid wear of the Needles and running surfaces of the journal bearing result. Because of the invention this deficiency is remedied.

Das Neue und Fortschrittliche besteht in der Anwendung ballig geformter Lagernadeln für den eingangs genannten Zweck. Bei einer bevorzugten Ausführungsform der Kreuzgelenke ist der Krümmungsradius der Mantellinie der Nadeln in an sich bekannter Weise gleich dem halben Durchmesser ihrer Außenlauffläche, so daß ein Kugelgelenk gebildet wird.What is new and progressive is the use of spherical ones Storage needles for the purpose mentioned above. In a preferred embodiment of the universal joints is the radius of curvature of the surface line of the needles in itself known Way equal to half the diameter of its outer running surface, making a ball joint is formed.

Es ist ein Rollenlager bekannt, bei dem die Rollen aus Kreisbogendrehkörpern bestehen, deren Erzeugende je ein um den Lagermittelpunkt beschriebener Kreisbogen ist. Die Abmessungen des Lagers und der Wälzkörper liegen hierbei jedoch so weit außerhalb des für Nadellagerungen in Betracht kommenden Bereiches, daß von dieser Konstruktion eine Anregung für die Gestaltung der Nadellagerung von Kreuzgelenkzapfen nicht ausgehen konnte. Ferner sind sogenannte Tonnenrollenlager mit ebenen oder gekrümmten Laufflächen seit langem bekannt. Aber erst durch die Erfindung sind die Vorteile ballig geformter Wälzkörper auch dem Sondergebiet der Nadellagerung bei Kreuzgelenken zugute gekommen. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung teils in Ansicht, teils im Schnitt dargestellt.A roller bearing is known in which the rollers consist of circular arc rotating bodies exist whose generators each have a circular arc described around the center of the bearing is. However, the dimensions of the bearing and the rolling elements are so far here outside of the range in question for needle bearings that of this Construction a suggestion for the design of the needle bearing of universal joint journals couldn't go out. Furthermore, so-called barrel roller bearings with flat or curved treads known for a long time. But only through the invention are they Advantages of spherical rolling elements also in the special field of needle bearings Universal joints benefited. An embodiment of the invention is in Drawing shown partly in view, partly in section.

Bei diesem Kreuzgelenk werden eine Gelenkwelle I und eine Gelenknabe 2, die in Gabelstücke 3 bzw. 4 auslaufen, durch ein Kreuzstück 5 kardanisch miteinander verbunden. Zu diesem Zweck sind die Gabelstücke 3 und 4 mit zylindrischen Durchbrechungen 6 versehen, in welchen die Lagerung der Gelenkzapfen 7 angeordnet ist. Diese besteht aus einer becherförmigen, nach innen zu offenen Hülse 8, auf deren Innenumfang ballig geformte Lagernadeln 9 angeordnet sind. Der Krümmungsradius r der Mantellinie der Lagernadeln 9 ist gleich dem halben Durchmesser- d der Außenlaufbahn Io .der Nadeln. Die Hülse 8 wird nach außen durch einen Federring II gesichert und ist innen durch eine Dichtung I2 abgedichtet, so daß weder Schmutz eindringen, noch Schmiermittel entweichen kann. .In this universal joint, a cardan shaft I and a joint hub 2, which terminate in fork pieces 3 and 4, gimbaled to one another by a cross piece 5 tied together. For this purpose, the fork pieces 3 and 4 have cylindrical openings 6 provided, in which the bearing of the pivot pin 7 is arranged. This exists from a cup-shaped, inwardly open sleeve 8, spherical on the inner circumference shaped bearing needles 9 are arranged. The radius of curvature r of the surface line of the Bearing needles 9 is equal to half the diameter of the outer raceway Io of the needles. The sleeve 8 is secured to the outside by a spring ring II and is through the inside a seal I2 sealed so that neither dirt nor lubricant penetrate can escape. .
