They have proven themselves in practice in large-scale production.

Der Erfindung liegt die Aufgabe zugrunde, eine Verbund- oder Koppellenker-Hinterachse der im Oberbegriff des Patentanspruchs 1 genannten Art weiter zu verbessern und zu vereinfachen und insbesondere so auszubilden, daß unter Beibehaltung der grundsätzlichen spurkorrigierenden und sonstigen gummielastischen Eigenschaften eine mechanisierte Montage der Hinterachse erleichtert wird.The invention is based on the object of a composite or coupling link rear axle of the type mentioned in the preamble of claim 1 to further improve and to simplify and in particular to train so that while maintaining the basic track-correcting and other rubber-elastic properties a mechanized Mounting the rear axle is facilitated.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.According to the invention, this object is achieved by the characterizing features of claim 1 solved.

Anhand eines in der Zeichnung dargestellten schematischen Ausführungsbeispieles wird die Erfindung nachstehend näher erläutert.On the basis of a schematic embodiment shown in the drawing the invention is explained in more detail below.

In der Zeichnung zeigen Fig. 1 ein Kraftfahrzeug mit der erfindungsgemäßen Verbund- oder Koppellenker-Hinterachse von unten gesehen und bei Geradeausfahrt, Fig. 2 die gleiche Ansicht des Kraftfahrzeugs bei Kurvenfahrt, Fig. 3 eine Detailansicht des in Fig. 1 mit III bezifferten Ausschnitts der Hinterachse und Fig. 4 eine Teilschnittansicht entlang der Schnittführung IV in Fig. 3.In the drawing, Fig. 1 shows a motor vehicle with the inventive Composite or coupling link rear axle viewed from below and when driving straight ahead, FIG. 2 shows the same view of the motor vehicle when cornering, FIG. 3 shows a detailed view of the section of the rear axle numbered III in FIG. 1 and FIG. 4 is a partial sectional view along the section line IV in FIG. 3.

Die Figuren 1 und 2 zeigen ein Kraftfahrzeug, dessen lenkbare Vorderräder mit 1 beziffert sind und dessen Hinterräder mittels einer sogenannten Verbund- oder Koppellenkerachse 3 schwenkbar am Fahrzeugaufbau 6 angelenkt sind. Die Verbund- oder Koppellenkerachse 3 besteht in üblicher Weise aus zwei im Abstand zueinander angeordneten starren Längslenkern 31 und 32, die einenends nicht weiter bezifferte Radträger oder Radachsen für die Hinterräder 2 tragen und anderenends über spurkorrigierende gummielastische Lager 4 und 5 am Fahrzeugaufbau 6 schwenkbar angelenkt sind.Figures 1 and 2 show a motor vehicle, the steerable front wheels are numbered with 1 and its rear wheels by means of a so-called composite or Coupling link axle 3 are pivotably articulated on the vehicle body 6. The composite or coupling link axle 3 consists in the usual way of two at a distance from one another arranged rigid trailing arms 31 and 32, one end not further numbered Wear wheel carriers or axles for the rear wheels 2 and at the other end via track-correcting rubber-elastic bearings 4 and 5 are pivotably articulated on the vehicle body 6.

Wie insbesondere die Figuren 3 und 4 erkennen lassen, sind die aufbauseitigen Enden der beiden Längslenker 31 und 32 mit vertikal ausgerichteten Gummi-Metall-Lagern 4 und 5 versehen, die durch zumindest annähernd vertikal gestellte Lagerbolzen 8 am Fahrzeugaufbau 6, insbesondere an Längsträgern des Fahrzeugaufbaus befestigt sind. Im gezeigten Ausführungsbeispiel erfolgt die Befestigung über am Fahrzeugaufbau angeordnete Widerlager 7.As can be seen in particular from FIGS. 3 and 4, the body-side Ends of the two trailing arms 31 and 32 with vertically aligned rubber-metal bearings 4 and 5 provided by at least approximately vertically posed Bearing pin 8 on the vehicle body 6, in particular on the longitudinal members of the vehicle body are attached. In the embodiment shown, it is attached via the Vehicle superstructure arranged abutment 7.

Die im Ausführungsbeispiel dargestellten vertikal ausgerichteten Gummi-Metall-Lager entsprechen in ihrem Grundaufbau im wesentlichen Lagern, wie sie im Kraftfahrzeugbau zur Anlenkung der oberen Federbein-oder Dämpferbeinenden am Fahrzeugaufbau Verwendung finden; sie lassen also insbesondere kugelige Bewegungen der aneinander angelenkten Bauelemente zu.The vertically aligned rubber-metal bearings shown in the exemplary embodiment essentially correspond in their basic structure to bearings such as those used in motor vehicle construction Used to link the upper strut or damper strut ends to the vehicle body Find; So they allow in particular spherical movements of the articulated Components too.

Die an den zugeordneten Längslenkern 31 bzw. 32 angeschweißten äußeren Metallhülsen 41 der Gummi-Metall-Lager 4 bzw. 5 weisen etwa in halber Höhe eine radiale Einschnürung 46 auf, von der aus sich die Hülse jeweils nach oben und nach unten trichterähnlich erweitert. Die gummielastischen Elemente der Gummi-Metall-Lager bestehen jeweils aus einem oberen ringförmigen Element 42a und einem unteren ringförmigen Element 42b. Diese liegen jeweils mit ihrer äußeren Mantelfläche an den äußeren Metallhülsen 41 an und können an dieser ggf. auch anvulkanisiert sein. Mit ihrer inneren Mantelfläche liegen die oberen ringförmigen gummielastischen Elemente 42a an einem topfförmig gestalteten Teil der Widerlager 7 und die unteren ringförmigen gummielastischen Elemente 42b an topfförmigen Spannhülsen 43 an, über welche die Lager mittels der Lagerbolzen 8 gegen die Widerlager 7 geschraubt werden.The outer ones welded to the associated trailing arms 31 and 32, respectively Metal sleeves 41 of the rubber-metal bearings 4 and 5 have a approximately halfway up radial constriction 46, from which the sleeve extends upwards and downwards widened like a funnel at the bottom. The rubber-elastic elements of rubber-metal bearings each consist of an upper annular element 42a and a lower annular element Element 42b. These are each with their outer surface on the outer Metal sleeves 41 and can optionally also be vulcanized onto them. With their The upper annular rubber-elastic elements 42a lie on the inner lateral surface on a cup-shaped part of the abutment 7 and the lower annular rubber-elastic elements 42b on cup-shaped clamping sleeves 43, via which the Bearing can be screwed against the abutment 7 by means of the bearing bolts 8.

Die beiden Gummi-Metall-Lager 4 und 5 weisen jeweils zwei nierenförmige Aussparungen 44, 45 bzw. 54, 55 auf, die - mit Bezug auf den zugehörigen Lagerbolzen 8 - einander diametral gegenüberliegen. Beim Ausführungsbeispiel, wo die gummielastischen Elemente der Gummi-Metall-Lager jeweils ein oberes und ein unteres ringförmiges gummielastisches Element 42a bzw. 42b enthalten, sind solche nierenförmigen Aussparungen sowohl im oberen als auch im unteren Element angeordnet. In Fig. 4 sind sie gestrichelt angedeutet und mit 44a bis 45b beziffert.The two rubber-metal bearings 4 and 5 each have two kidney-shaped bearings Recesses 44, 45 and 54, 55, which - with reference to the associated bearing pin 8 - diametrically opposed to each other. In the embodiment where the rubber-elastic Elements of the rubber-metal bearing each have an upper and a lower ring-shaped rubber-elastic element 42a and 42b contain, such kidney-shaped recesses arranged in both the upper and lower element. In Fig. 4 they are dashed indicated and numbered 44a to 45b.

Wie insbesondere den Figuren 1 bis 3 zu entnehmen ist, sind die Gummi-Metall-Lager 4 und 5 der beiden Längslenker 31 und 32 räumlich derart angeordnet und ausgerichtet, daß die nierenförmigen Aussparungen 44a bis 45b diagonal zur Fahrzeuglängs- bzw. -querachse liegen, d. h.As can be seen in particular from FIGS. 1 to 3, the rubber-metal bearings are 4 and 5 of the two trailing arms 31 and 32 spatially in such a way arranged and aligned that the kidney-shaped recesses 44a to 45b diagonally to the vehicle longitudinal or transverse axis, d. H.

daß jeweils durch die beiden nierenförmigen Aussparungen gelegte fiktive Geraden A bzw. B (Fig. 1) sich in der Draufsicht fahrzeugmittig schneiden. Wenn die Ausrichtung der Gummi-Metall-Lager 4 und 5 - wie im Ausführungsbeispiel - derart geschieht, daß sich die beiden Geraden A und B in einem vor den aufbauseitigen Lagern liegenden Punkt S schneiden, werden eventuell vorhandene Übersteuertendenzen des Fahrzeuges beim Durchfahren von Kurven abgebaut bzw. beseitigt, weil dann die Verbund- oder Koppellenker-Hinterachse 3 bei Kurvenfahrt selbsttätig in Richtung Nachspur verschwenkt wird, wie dies in Fig. 2 angedeutet ist. Dort ist die durch die Radachsen der Hinterräder 2 verlaufende fiktive Achse im Vergleich zur Geradeausfahrt um den Winkel g verschwenkt. Bei Kurvenfahrt wird nämlich die Verbund-oder Koppellenkerachse 3 unter der Wirkung angreifender Seitenkräfte quer zum Fahrzeugaufbau verschoben, weil sie sich in den aufbauseitigen Lagern 4 und 5 in Richtung des geringsten Widerstandes bewegt, der durch die räumliche Lager der nierenförmigen Aussparungen bestimmt wird. In Fig. 2 ist erkennbar, daß bei der dort angenommenen Fahrtrichtung jeweils die nierenförmigen Ausnehmungen 45 des Lagers 4 und 54 des Lagers 5 zusammengedrückt und die Ausnehmungen 44 des Lagers 4 bzw. 55 des Lagers 5 aufgeweitet werden.that each put through the two kidney-shaped recesses fictitious Straight lines A and B (Fig. 1) intersect in the center of the vehicle when viewed from above. if the alignment of the rubber-metal bearings 4 and 5 - as in the exemplary embodiment - in such a way happens that the two straight lines A and B are in a front of the superstructure bearings intersect the lying point S, any oversteering tendencies of the Vehicle dismantled or removed when driving through curves, because then the composite or coupling arm rear axle 3 automatically in the direction of toe-out when cornering is pivoted, as indicated in FIG. There is the one through the axles of the rear wheels 2 running fictitious axis compared to driving straight ahead around the Angle g pivoted. When cornering, namely the compound or coupling link axle 3 moved transversely to the vehicle body under the effect of acting lateral forces, because they are in the body-side bearings 4 and 5 in the direction of the least resistance moved, which is determined by the spatial bearing of the kidney-shaped recesses. In Fig. 2 it can be seen that in each case the direction of travel assumed there kidney-shaped recesses 45 of the bearing 4 and 54 of the bearing 5 are compressed and the recesses 44 of the bearing 4 and 55 of the bearing 5 are widened.

Wenn abweichend vom dargestellten Ausführungsbeispiel die beiden Gummi-Metall-Lager 4 und 5 dagegen räumlich derart ausgerichtet werden, daß sich die vorerwähnten Geraden A und B in einem hinter den aufbauseitigen Lagern 4 und 5 liegenden Punkt schneiden, dann würde die Verbund- oder Koppellenkerachse 3 bei Kurvenfahrt nicht in Richtung Nachspur, wie in Fig. 2 gezeigt, sondern in Richtung Vorspur ausgelenkt werden, wodurch eine durch entsprechenden Radeinschlag der Vorderräder 1 eingeleitete Kurvenfahrt zusätzlich unterstützt würde; eventuell bereits vorhandene Übersteuertendenzen des Fahrzeuges können dadurch also vergrößert bzw. nicht vorhandene Übersteuertendenzen überhaupt erst erzeugt werden.If different from the illustrated embodiment, the two rubber-metal bearings 4 and 5, however, are spatially aligned in such a way that the aforementioned straight lines Cut A and B at a point behind the superstructure bearings 4 and 5, then the composite or coupling link axle 3 would not be in the direction when cornering Toe-out, as shown in Fig. 2, but be deflected in the direction of toe-in, whereby a cornering initiated by appropriate wheel lock of the front wheels 1 would be additionally supported; possibly already existing oversteer tendencies of the The vehicle can thus be enlarged or there is no oversteering tendency are generated in the first place.

Der konstruktive und fertigungstechnische Aufwand für die erfindungsgemäße Verbund- und Koppellenker-Hinterachse ist vergleichsweise gering und den jeweiligen Bedürfnissen des Fahrzeuges in einfachster Weise anzupassen. Von besonderem Vorteil ist, daß die Hinterachse sehr gut für eine automatisierte Montage geeignet ist, weil die Lagerbolzen 8 von unten angeschraubt werden, die ggf. durch nicht weiter dargestellte Federbeine o. ä. komplettierte Verbund- oder Koppellenkerachse 3 bei der Fertigmontage also automatisch von unten gegen den Fahrzeugaufbau geführt und ebenfalls automatisch mit den Lagerbolzen 8 daran befestigt werden kann.The design and manufacturing effort for the inventive Composite and coupling link rear axle is comparatively low and the respective Adapt the needs of the vehicle in the simplest possible way. Of particular advantage is that the rear axle is very suitable for automated assembly, because the bearing bolts 8 are screwed on from below, which may not continue through Shown struts o. Ä. Completed composite or coupling link axle 3 at the final assembly so automatically guided from below against the vehicle body and can also be automatically attached to it with the bearing pin 8.
