Description

Der Erfindung liegt die Aufgabe zugrunde, diese Nachteile zu vermeiden und eine Radaufhängung der eingangs genannten Art zu schaffen, bei der im wesentlichen nur der Fahrgastraum verformungssteif gehalten werden muß. Die Erfindung besteht darin, daß zur Aufnahme der Abstützkräfte der Vorderräder und der Hinterräder durch Federkraft belastete quer zur Fahrtrichtung schwingende Schwinghebel vorgesehen sind, die in der Nullage ansteigenden Ebenen innerhalb des Radstandes gelagert sind. Eine äußerst vorteilhafte Ausführungsform der Erfindung erhält man, wenn die als Schwinghebel ausgebildete starre in Fahrtrichtung ausgekröpfte Hinterachse in einem Achsträger um eine zu den Radachsen parallele Achse schwingend gelagert ist, der in der Fahrzeugmittelebene um eine in Fahrzeugslängsrichtung liegende Achse schwingend gelagert ist. In baulich einfacher Weise kann die Hinterachse mittels schräg nach vorne gerichteter Federn an einem hochliegenden Punkt des Fahrzeugaufbaues abgestützt sein. In vorteilhafter Weise werden bei dieser Ausführungsform die im allgemeinen schräg gerichteten stoßartigen Belabt-#ingen der Hinterachse in Richtung der Federachsen aufgenommen. Zweckmäßigerweise kann das hintere Lager des Achsträgers innerhalb des Radstandes liegen und mittels Streben an einem hochliegenden Punkt, vorzugsweise dem Hauptquerträger des Fahr- mittels an dem Achsträger befestigter Zugfedern abgestützt sein. auch möglich, wie in Fig. 1 gestrichelt dargestellt ist#, den Achsträger 121 Über die Radmitten hinaus nach hinten zu verlängern und dort das hintere Lager 15t anzuordn . en, das ebenfalls-mittels Streben an-dem Fahrzeugaufbau befpstigt"werdenkann. Um zu erreichen,-äß die Federn 16 nur mit den durch Kurvenneigung o.dgl. hervorgerufenen Kräft en belastet werden,_ sind an'der Hinterachse 11-Hebel 17 angeordnet, die mit Zugfedern 18 belastet sind, welche in der Nähe des vorderen Lagers 14 des Achsträgers 12 an von dem Achsträger 12 abstehenden Hebeln 19 befestigt sind..Diese Zugfedern 18, die gegen ein Verdrehen der Hinterachse 11 wirken" nehmen die aus dem-Eigengewicht des Personenkraftwagens 1 regültierenden Kräfte auf. The invention has for its object to avoid these disadvantages and to provide a wheel suspension of the type mentioned, essentially only the passenger compartment must be kept rigid at the deformation. The invention consists in that, to absorb the supporting forces of the front wheels and the rear wheels, rocker arms, which are loaded by spring force and oscillate transversely to the direction of travel, are provided which are in the zero position rising levels are stored within the wheelbase. An extremely advantageous embodiment of the invention is obtained when the rigid rear axle, which is cranked in the direction of travel, is mounted in an axle carrier swinging around an axis parallel to the wheel axles, which is mounted swinging in the vehicle center plane about an axis lying in the longitudinal direction of the vehicle. In a structurally simple manner, the rear axle can be supported at an elevated point on the vehicle structure by means of springs directed obliquely forwards. Advantageously, in this embodiment, the generally obliquely directed shock-like bellows of the rear axle are received in the direction of the spring axles. Appropriately, the rear bearing of the axle carrier can be located within the wheelbase and by means of struts at a high point, preferably the main cross member of the vehicle. be supported by means of tension springs attached to the axle support. also possible, as shown in dashed lines in FIG. 1 , to extend the axle support 121 to the rear beyond the wheel centers and to arrange the rear bearing 15t there . That can also be attached to the vehicle body by means of struts. In order to achieve that the springs 16 are only loaded with the forces caused by the inclination of a curve or the like, levers 17 are arranged on the rear axle 11 that are loaded with springs 18, which in the vicinity of the front bearing 14 of the axle support 12 at protruding from the axle beam 12 levers 19 fixed sind..Diese tension springs 18 which act against a rotation of the rear axle 11 take "resulting from the own weight of the passenger car 1 regulating forces.

Durch die Anordnung der Schwinghebel 8 und 11 in einer annähernd gemeinsamen, nach vorne leicht ansteigenden Ebene 20 wird eine für das Fahrzeug 1 äußerst vorteilhafte Radäufhängung geschaffen, die außerdem noch den*Vorteil haft, cW sie-Mit einer äußerst geringen Zahrzeugseitigen Anzahl von- Iagergestellen auskommt.The arrangement of the rocker arms 8 and 11 in an approximately common, slightly upwardly inclined plane 20 creates an extremely advantageous wheel suspension for the vehicle 1 , which also has the advantage of having an extremely low number of storage racks on the vehicle side gets by.
