Description

Die Erfindung bezieht sich auf eine Aufhängung einer gefederten Starrachse bei Fahrzeugen, insbesondere Kraftfahrzeugen, mit zwei die Starrachse führenden Längslenkern, die durch einen querliegenden, als Stabilisator wirkenden Drehstab zu einem einstückigen Bügel verbunden sind.The invention relates to a suspension of a sprung rigid axle in vehicles, in particular Motor vehicles, with two trailing arms leading to the rigid axle, which by a transverse, as Stabilizer acting torsion bar are connected to a one-piece bracket.

Bei einer bekannten Aufhängung dieser Art ist der aus den beiden Längslenkern und dem Drehstab bestehende Bügel U-förmig ausgeführt. Dabei werden die Längslenker nicht nur zur Führung der Achse herangezogen, sondern dienen auch zur Übertragung der in Fahrzeuglängsrichtung auftretenden Kräfte von der Achse auf den Fahrzeugrahmen. Bei einer Querneigung des Fahrzeuges werden die beiden Längslenker verschieden weit verschwenkt und es ergibt sich eine Verdrehung des Drehstabes, der dadurch der Querneigung des Fahrzeuges Rückstellkräfte entgegengesetzt und so a!s Stabilisator wirkt. Querkräfte, also parallel zur Achse verlaufende Kräfte, können bei einer solchen Anordnung aber nicht aufgenommen bzw. übertragen werden, weshalb für diesen Zweck ein weiterer Konstruktionsteil, nämlich wenigstens ein Querlenker oder ein sogenannter Panhard-Stab, vorgesehen werden muß, der den Konstruktionsaufwand erhöhtIn a known suspension of this type that consists of the two trailing arms and the torsion bar existing bracket U-shaped. The trailing arms are not only used to guide the axle used, but are also used to transfer the forces occurring in the longitudinal direction of the vehicle the axle on the vehicle frame. If the vehicle is banked, the two will The trailing arm is pivoted differently and the torsion bar rotates thereby counteracting the lateral inclination of the vehicle, restoring forces and acting as a stabilizer. However, transverse forces, i.e. forces running parallel to the axis, cannot be used with such an arrangement recorded or transferred, which is why a further structural part for this purpose, namely at least one wishbone or a so-called Panhard rod must be provided that the Construction effort increased

Bekannt ist weiterhin, eine Hinterachse mittels eines geschlossenen rechteckigen Rahmens zu führen. Hierbei müssen zur Aufnahme der Querkräfte alle Rahmenschenkel eine ausreichende Biegesteifigkeit aufweisen, ohne ihre Verdrehsteifigkeit übermäßig zu vergrößern. Das ist nur mit aufwendigen Querschnittsformen erreichbar. It is also known to guide a rear axle by means of a closed rectangular frame. Here All frame legs must have sufficient flexural strength to absorb the transverse forces without excessively increasing their torsional rigidity. This can only be achieved with complex cross-sectional shapes.

Somit liegt der Erfindung die Aufgabe zugrunde, diese Mangel zu beseitigen und eine Aufhängung der eingangs geschilderten Art zu schaffen, bei der ohne zusätzliche Konstruktionsteile mit der geringstmöglichen Anzahl von Lagerstellen auch die Querkräfte einwandfrei übertragen werden können.Thus, the invention is based on the object to eliminate this deficiency and a suspension of the To create the type described above, with the least possible without additional structural parts Number of bearing points, the transverse forces can also be transmitted properly.

Die Erfindung löst die gestellte Aufgabe dadurch, daß der von den beiden Längslenkern und dem Drehstab gebildete Bügel Z-förmig gestaltet ist wobei die Gelenke an den freien Schenkelenden und an den Scheiteln des Bügels angeordnet sind.The invention solves the problem in that the two trailing arms and the torsion bar formed bracket is designed Z-shaped with the joints at the free leg ends and at the Vertices of the stirrup are arranged.

Der Drehstab wird von dem die beiden Schenkel verbindenden Schrägteil des Bügels gebildet und erfüllt seine Aufgabe als Stabilisator in der gleichen Weise wie bei der bekannten U-Form des Bügels. Die Übertragung der Längskräfte und die Führung der Starrachse durch die die Längslenker bildenden Bügelschenkel erfährt ebenfalls keinerlei Beeinträchtigung. Jener Winkelteil des Bügels, der aus dem der Starrachse benachbarten Bügelscheitel, dem von diesem ausgehenden Schenkel bzw. Längslenker und dem Schrägteil des Bügels besteht, stellt nun aber einen Dreieckslenker dar, der die auf die Starrachse wirkenden, quer zum Fahrzeug gerichteten Kräfte einwandfrei zu übertragen vermag, so daß sich jed.er zusätzliche Querlenker, Panhard-Stab od. dgl. erübrigt und eine sehr einfache Konstruktion erzielt wird, bei der insgesamt nur vier Gelenke, vorzugsweise Gummigelenke, vorhanden sind. Die von den Anfahr- und Bremskräften herrührenden Drehmomente auf die Achse können mittels der ohnehin vorhandenen Federn oder durch bekannte Drehmomentstützen aufgefangen werden.The torsion bar is formed and fulfilled by the inclined part of the bracket connecting the two legs its role as a stabilizer in the same way as with the well-known U-shape of the bracket. The transfer experiences the longitudinal forces and the guidance of the rigid axle through the bow legs forming the trailing arm also no impairment. That angular part of the bracket from that adjacent to the rigid axis Bracket crown, the leg or trailing arm extending from this and the inclined part of the bracket exists, but now represents a wishbone that acts on the rigid axle, transversely to the vehicle able to transmit directed forces properly, so that each additional wishbone, Panhard rod or the like is unnecessary and a very simple construction is achieved in which a total of only four joints, preferably rubber joints are present. The torques resulting from the starting and braking forces on the axle can be done by means of the springs that are already present or by means of known torque arms be caught.

Um den Bügel aus einem einfachen Stab herstellen und dennoch die Gelenke im Scheitelbereich anordnen zu können, sind erfindungsgemäß die Bügelscheitel in miteinander verschraubten Halbschalen gefaßt, von denen jeweils eine einen kurzen Ansatzarm mit Lagerauge trägt.To make the bracket from a simple rod and still arrange the joints in the crown area to be able to, according to the invention, the bow vertices are taken in half-shells screwed together, from each of which has a short arm with bearing eye.
