Description

  

      Vielrädriger        Schwerlastanhänger       Die Erfindung bezieht sich auf einen vielrädrigen       Schwerlastanhänger    mit Tragrahmen und an Pendelach  sen gelagerten, lenkbaren Rädern. Ihr     liegt    die Aufga  be     zugrunde,    für einen derartigen Anhänger einen       möglichst        gedrungenen,    wenig Platz in Anspruch neh  menden Aufbau der     Radaufhängung    und     -abfederung     zu schaffen und dadurch vor allem den maximal mög  lichen Lenkausschlag jedes     einzelnen    Rades zu erhöhen.

    Zur     Lösung    dieser Aufgabe sieht die Erfindung vor,  dass jede Pendelachse von einer Lenksäule getragen  wird, die gegen den Tragrahmen abgefedert in einer  am Tragrahmen     angelenkten    Achsschwinge drehbar ist.  Auf diese Weise wird mit einem     Minimum    an Bautei  len ein Aufbau geschaffen, der am Tragrahmen nur we  nig Platz in Anspruch nimmt, wobei zugleich jede Be  grenzung des Lenkausschlages der Räder, soweit sie von  der     Radaufhängung    herrührt, entfällt, so dass der maxi  male Ausschlag allein vom Lenkgestänge abhängt.  



  Besonders einfach gestaltet sich der Aufbau, wenn  jeder Pendelachse eine Blattfeder zugeordnet wird,     an     der sich die Lenksäule mittels eines Druckgelenks ab  stützt. Die Verwendung von Blattfedern ermöglicht es  überdies, in bekannter Weise mehrere Räder zu einer  Gruppe mit Geländeausgleich zusammenzufassen, und  zwar durch Kopplung der zugehörigen     Federn    mit  tels     Ausgleichhebel.    Auch hier ist eine weitere Verein  fachung     im    Aufbau dadurch möglich, dass die Ausgleich  hebel in den Gelenken der     Achsschwingen    gelagert  werden.  



  Die Zeichnung     veranschaulicht    einige Ausführungs  beispiele     in    schematisch vereinfachter Darstellung. Es  zeigen:       Fig.    1 die     Aufhängung    einer     einzelnen    Pendelachse  in Ansicht von der Seite, teilweise im Schnitt,       Fig.    2     in    entsprechender Darstellung eine zwei Pen  delachsen umfassende Radgruppe mit Geländeausgleich,         Fig.    3     eine    entsprechende Gruppe mit insgesamt  drei Pendelachsen,

         Fig.    4 einen Schnitt nach Linie     IV-IV    in     Fig.    1 und       Fig.    5 eine der     Fig.    2 oder 3 entsprechende Gruppe,  jedoch mit     insgesamt    vier Pendelachsen.

      Bei der Ausführung nach     Fig.    1 ist am Tragrah  men 1 in einem Gelenk 2     eine    Achsschwinge 3     um     eine horizontale Achse schwenkbar gelagert, wobei sich  die Schwenkachse quer zur Fahrtrichtung erstreckt, so  dass die Achsschwinge 3 in     einer        zur    Fahrtrichtung  parallelen     Vertikalebene        schwingt.     



  Die Achsschwinge 3 bildet den Träger einer Lenk  säule 4, die in Büchsen 5 der     Achsschwinge    3 um eine  Achse drehbar ist, die in der gezeichneten Grundstel  lung der Schwinge 3 vertikal     liegt.    Am unteren Ende  der Lenksäule 4 ist um einen waagerechten Zapfen 6  eine Pendelachse 7 frei drehbar, an deren Enden in der  üblichen Weise je ein Rad 8 gleichfalls frei drehbar  gelagert ist. Mit der Lenksäule 4 ist ein Hebel 9 fest  verbunden, der einen Teil des Lenkgestänges des Fahr  zeuges bildet, also durch weitere, nicht gezeichnete     Ge-          stängeteile    eine Schwenkung erfahren kann, die der  Lenksäule 4 und damit der Pendelachse 7 und den       Rädern    8 mitgeteilt wird.  



  Oberhalb der Lenksäule 4 ist eine zweiarmige  Blattfeder 10 angeordnet deren eines Ende durch ein  Gelenk 11 mit dem Tragrahmen 1 direkt verbunden  ist, während das andere Ende 12 durch eine     Lasche     13, wie sie bei Federgehängen     üblich    ist, über ein Ge  lenk 14 an den Rahmen 1 angeschlossen ist. Zwischen  der Lenksäule 4 und der Feder 10 ist ein in     Fig.    1 nur  schematisch angedeutetes, in     Fig.    4 genauer gezeichne  tes Druckgelenk 15 angeordnet, also ein Gelenkstück,  mittels dessen sich die Lenksäule an der Feder 10 ab  stützt, ohne dass sie in     ihrer        Drehung    behindert ist.

        Die     Ausführung    nach     Fig.    2 unterscheidet sich von  derjenigen nach     Fig.    1     lediglich    dadurch, dass zwei  Achsschwingen 4 mit ihren     Rädern    8 zu einer Rad  gruppe mit Geländeausgleich     zusammengefasst        sind.    Zu  diesem Zweck sind die einander gegenüberstehenden  Enden der beiden     Federn    10 nicht     direkt    am Rahmen  1 aasgelenkt, sondern über die Laschen 13 an die En  den eines     Ausgleichhebels   <B>16</B> angeschlossen, der am  Rahmen 1 gelagert ist,

   und zwar zur     baulichen    Verein  fachung im     Gelenkpunkt    2 der einen Achsschwinge 3.  



  Ganz entsprechend sind die     Ausführungen    nach     Fig.     3 und 5 gestaltet,     in    denen drei Pendelachsen bzw. vier  Pendelachsen mit den     zugehörigen    Rädern zu     einer     Gruppe     mit    Geländeausgleich     zusammengefasst    sind.

   Bei  der Ausführung nach     Fig.    3 ist demgemäss die Feder  10 des mittleren Radpaares an beiden Enden über Aus  gleichhebel 16 an die beiden übrigen Federn angekop  pelt und bei der     Ausführung    nach     Fig.    5 sind die bei  den mittleren Federn 10 durch einen     Ausgleichhebel     16 miteinander und durch weitere     Ausgleichhebel    16  an die beiden äusseren Federn angekoppelt.



      Multi-wheel heavy-duty trailer The invention relates to a multi-wheel heavy-duty trailer with a support frame and steerable wheels mounted on Pendelach sen. It is based on the task of creating a compact, compact, space-consuming construction of the wheel suspension and cushioning for such a trailer and thereby increasing the maximum possible steering angle of each individual wheel.

    To solve this problem, the invention provides that each pendulum axle is carried by a steering column which is sprung against the support frame and rotatable in an axle rocker articulated on the support frame. In this way, with a minimum of components, a structure is created that takes up little space on the support frame, while at the same time any limitation of the steering angle of the wheels, as far as it comes from the wheel suspension, is omitted, so that the maximum deflection depends solely on the steering linkage.



  The structure is particularly simple if a leaf spring is assigned to each pendulum axle, on which the steering column is supported by means of a pressure joint. The use of leaf springs also makes it possible in a known manner to combine several wheels into a group with terrain compensation, by coupling the associated springs with means of compensation lever. Here, too, a further simplification of the structure is possible in that the compensation levers are stored in the joints of the axle swing.



  The drawing illustrates some execution examples in a schematically simplified representation. 1 shows the suspension of an individual pendulum axle in a view from the side, partially in section, FIG. 2 shows a corresponding representation of a wheel group comprising two pendulum axles with terrain compensation, FIG. 3 shows a corresponding group with a total of three pendulum axles,

         4 shows a section along line IV-IV in FIG. 1 and FIG. 5 shows a group corresponding to FIG. 2 or 3, but with a total of four pendulum axes.

      In the embodiment according to Fig. 1, a swing arm 3 is pivotably mounted about a horizontal axis on the Tragrah men 1 in a joint 2, the pivot axis extending transversely to the direction of travel, so that the swing arm 3 swings in a vertical plane parallel to the direction of travel.



  The swing arm 3 forms the support of a steering column 4, which is rotatable in sockets 5 of the swing arm 3 about an axis which is in the basic stel development of the rocker arm 3 is vertical. At the lower end of the steering column 4, a pendulum axle 7 is freely rotatable about a horizontal pin 6, at the ends of which a wheel 8 is also freely rotatably mounted in the usual manner. With the steering column 4, a lever 9 is firmly connected, which forms part of the steering linkage of the driving tool, ie can experience a pivoting through further, not shown linkage parts, which is communicated to the steering column 4 and thus the pendulum axle 7 and the wheels 8 .



  Above the steering column 4, a two-armed leaf spring 10 is arranged one end of which is directly connected by a hinge 11 to the support frame 1, while the other end 12 by a tab 13, as is common with spring hangers, via a Ge joint 14 to the frame 1 is connected. Between the steering column 4 and the spring 10 is a only schematically indicated in Fig. 1, more precisely drawn in Fig. 4 th pressure joint 15 is arranged, so a joint piece by means of which the steering column is supported on the spring 10 without them in their Rotation is hindered.

        The embodiment according to FIG. 2 differs from that according to FIG. 1 only in that two axle rockers 4 are combined with their wheels 8 to form a wheel group with terrain compensation. For this purpose, the opposing ends of the two springs 10 are not articulated directly on the frame 1, but are connected via the tabs 13 to the ends of a compensating lever <B> 16 </B> which is mounted on the frame 1,

   namely for structural simplification in the pivot point 2 of one axle swing arm 3.



  The designs according to FIGS. 3 and 5 are designed accordingly, in which three pendulum axles or four pendulum axles with the associated wheels are combined to form a group with terrain compensation.

   In the embodiment according to FIG. 3, the spring 10 of the middle pair of wheels is accordingly pelt at both ends via equal lever 16 to the other two springs and in the embodiment according to FIG. 5, the middle springs 10 are connected to each other by a compensation lever 16 coupled to the two outer springs by further compensating levers 16.
