Abstract

The suspension element is made from a one piece plastic moulding whose central section (10) has an H-cross section, of thin walled construction. Spherical ball joint shells (11, 12) are moulded to the ends. Polyoxymethylene is used to provide good torsional strength and strong tensile support. Sealing gaskets (23) are clamped over the ball and socket joints, using grooves moulded over the shells. The central section of the H shape lies parallel to the ball joint axes. The whole element is light and strong.

Description

Drehstabgestänge Die Erfindung betrifft ein Drehstabgestänge für die Radaufhängung eines Kraftfahrzeuges, bestehend aus einer Verbindungsstange aus Kunststoff mit an ihren beiden Enden integriert angeformten Kugepfannen aus demselben Kunststoff, in welche abgedichtet Kugelbolzen eingerastet sind.Torsion bar linkage The invention relates to a torsion bar linkage for Wheel suspension of a motor vehicle, consisting of a connecting rod made of plastic with integrated molded spherical sockets made of the same plastic at both ends, in which sealed ball pins are locked.

Ein derartiges bekanntes Drehstabgestänge besteht aus Polyurethan, wobei an den Kugelpfannen integrierte Dichtmanschetten für die Kugelbolzen angeformt sind. Ein derartiges Gestänge hat den Nachteilj daß die Verbindungsstange, um genügend formsteif zu sein, sehr dickwandig ausgeführt sein muß, außerdem ist es durch die angeformten Dichtmanschetten kompliziert und damit teuer in der Herstellung.Such a known torsion bar is made of polyurethane, with integrated sealing collars for the ball studs formed on the ball sockets are. Such a linkage has the disadvantage that the connecting rod to enough to be dimensionally stable, must be made very thick-walled, in addition, it is through the molded sealing sleeves are complicated and therefore expensive to manufacture.

Es ist eine Aufgabe der Erfindung ein Drehstabgestänge der eingangs erwähnten Art zu schaffen, das fest, leicht und einfach herzustellen ist.It is an object of the invention a torsion bar linkage of the opening paragraph type that is strong, light and easy to manufacture.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst5 daß die Verbindungsstange samt den Kugelpfannen aus Polyoxymethylen besteht und daß die Verbindungsstange H-förmigen Querschnitt mit einem relativ dünnen Steg und dünnen Flanschen aufweist.This object is achieved according to the invention in that the connecting rod including the ball sockets is made of polyoxymethylene and that the connecting rod Has an H-shaped cross-section with a relatively thin web and thin flanges.

Das hat den Vorteil, daß die Verbindungsstange aus zäh-steifem Material besteht, das außerdem noch gute Gleiteigenschaften für die Kugelgelenke aufweist. Zweckmäßig ist es, die Dichtmanschette aus einem gummielasFtischen Werkstoff herzustellen, wodurch sie eine hohe Lebensdauer besitzt.This has the advantage that the connecting rod is made of a tough, stiff material exists, which also has good sliding properties for the ball joints. It is useful to manufacture the sealing sleeve from a rubber-elastic material, whereby it has a long service life.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung, der Zeichnung und den Unteransprüchen.Further advantageous refinements of the invention emerge from the following description, the drawing and the subclaims.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung wiedergegeben. Diese zeigt in Fig. 1 einen Längsschnitt durch ein Drehstabgestänge; Fig. 2 einen Schnitt längs II-II nach Fig. 1.An embodiment of the invention is shown in the drawing. This shows in Fig. 1 a longitudinal section through a torsion bar linkage; Fig. 2 a Section along II-II according to FIG. 1.

Das Drehstabgestänge besteht aus einer Verbindungsstange 10, an welcher integriert zwei Kugelpfannen 11, 12 mit entgegengesetzten öffnungsrichtungen angefomt sind, deren Achsen parallel zueinander verlaufen. Die Verbindungsstange sanit den angeformten Kugelpfannen werden in einem Arbeitsgang aus Polyoxymethylen hergestellt, das in viskostatischem Zustand in eine Form gepreßt wird.The torsion bar consists of a connecting rod 10 on which integrates two ball sockets 11, 12 with opposite opening directions are whose axes are parallel to each other. The connecting rod sanit the molded ball sockets are made from polyoxymethylene in one operation, which is pressed into a mold in a viscostatic state.

Weiterhin besteht das Drehstabgestänge aus zwei Kugelbolzen 13, 1h, welche in die Kugelpfannen dadurch eingerastet sind, daß diese an ihrer Öffnung einen etwas kleineren Durchmesser aufweisen als die Kugeln. Jeder Kugelbolzen besitzt einen Fortsatz 15 bzw. 16 mit einer Schlüsselfläche 17 bzw. 18 und einem Gewindebolzen 19 bzw. 20 sowie einer Ringnut 21 bzw. 22, welche zwischen der Kugel und der Schlüsselfläche liegt.Furthermore, the torsion bar consists of two ball pins 13, 1h, which are locked into the ball sockets by the fact that they are at their opening have a slightly smaller diameter than the balls. Each ball stud has an extension 15 or 16 with a key surface 17 or 18 and a threaded bolt 19 or 20 and an annular groove 21 or 22, which between the ball and the key surface lies.

Teil des Verbindungsgestänges ist außerdem noch eine jedem Kugelbolzen zugeorndete Dichtmanschette 23 bzw. 24 aus gummielastischem Werkstoff. Im folgenden ist nur die Dichtmanschette 23 weiter beschrieben, da die andere sowie ihre Befestigung gleich sind. Die Dichtmanschette 23 besitzt an ihrem eine Ende einen Eund 2:i, welcher in eine äußere Ringnut 25 an der Kugelpfanne greift, sowie einen Bund 26 an der anderen Seite der Manschette, welcher in die Ringnut 21 greift. Dadurch ist das Kugelgelenk gut abgedichtet.Part of the connecting rod is also one of each ball stud assigned sealing collar 23 or 24 made of rubber-elastic material. Hereinafter only the sealing collar 23 is further described, as the other and its attachment are the same. The sealing collar 23 has at one end an E and 2: i, which engages in an outer annular groove 25 on the ball socket, and a collar 26 on the other side of the cuff, which engages in the annular groove 21. This is how it is Ball joint well sealed.

Wie die Fig. 2 zeigt, besitzt die Verbindungsstange SI-förmigen Querschnitt, wobei der Steg 28 in derselben Ebene liegt wie die Achsen der Kugelgelenke. Die Flanschen 29 und 30 sind so breIt wie die Durchmesser der Kugelpfannen. Steg und Flanschen sind relativ dünn ausgebildet. Die Verbindungsstange 10 bildet mit den Achsen der Kugelpfannen einen Winkel, der etwas kleiner als 90 ° ist.As shown in Fig. 2, the connecting rod has an SI-shaped cross-section, wherein the web 28 lies in the same plane as the axes of the ball joints. the Flanges 29 and 30 are as wide as the diameter of the ball sockets. Bridge and Flanges are made relatively thin. The connecting rod 10 forms with the Axes of the ball sockets one Angle that is slightly smaller than 90 ° is.

Die Kugelzapfen besitzen an ihren in den Kugelpfannen liegenden Enden Abflachungen 31 bzw. 32, wodurch sich Räume bilden, die mit einem Schmiermittel gefüllt sind.The ball studs have their ends lying in the ball sockets Flats 31 and 32, which form spaces with a lubricant are filled.
