Abstract

Die Erfindung bezieht sich auf ein Strassenfahrzeug mit zwei Fahrzeugteilen, die über ein Gelenk miteinander verbunden sind, das mit Dämpfungs- und/oder Blockiereinrichtungen versehen ist, um das ungewollte Zusammenklappen der Fahrzeugteile zu vermeiden. Die Dämpfungs- und/oder Blockiereinrichtungen umfassen beiderseits des Gelenks je ein Paar von Stützarmen, deren Endplatten auf der Knickungsinnenseite des Gelenks aneinander anliegen und zwecks Dämpfung bzw. Blockierung durch beispielsweise hydraulische Mittel gegeneinander gepresst werden. - Damit sich diese Platten nicht ruckweise gegeneinander verschieben, sind sie mit ineinandergreifenden Erhöhungen und Vertiefungen versehen, die in der Art einer Verzahnung ausgeführt sein können.The invention relates to a road vehicle with two vehicle parts that are connected to one another via a joint that is provided with damping and / or blocking devices in order to avoid the unwanted folding of the vehicle parts. The damping and / or blocking devices each comprise a pair of support arms on both sides of the joint, the end plates of which rest against one another on the inside of the joint and are pressed against one another for damping or blocking purposes, for example by hydraulic means. - So that these plates do not move jerkily against each other, they are provided with interlocking elevations and depressions, which can be designed in the manner of a toothing.

Description

Die Erfindung bezieht sich auf ein Straßenfahrzeug mit zwei Fahrzeugteilen, die über ein Gelenk miteinander verbunden sind, das mit Dämpfungs- und/ oder Blockiereinrichtungen versehen ist, die beiderseits des Gelenks je ein Paar von Stützarmen umfassen, deren Enden bei Knickung des Gelenks in einem Richtungssinn mit Anschlagflächen gegeneinander gespannt sind.The invention relates to a road vehicle with two vehicle parts which are connected to one another via a joint, which is provided with damping and / or blocking devices, each comprising a pair of support arms on either side of the joint, the ends of which, when the joint is bent in one direction are clamped against each other with stop surfaces.

Es sind Stützarme bekannt, deren Anschlagplatten zwecks besserer Abwälzung konvex gegeneinander gewölbt sind. Dies führt im allgemeinen zu einwandfreier Funktion; jedoch hat man festgestellt, daß in manchen Fällen die Dämpfungskraft sich ruckweise ändert. Man glaubte zunächst, daß für die ruckweise Änderung der Dämpfungskraft irgendwelche Fehler in der Dämpfungshydraulik verantwortlich seien.Support arms are known, the stop plates of which are convexly curved for the purpose of better rolling. This generally leads to proper functioning; however, it has been found that in some cases the damping force changes jerkily. It was initially believed that any errors in the damping hydraulics were responsible for the jerky change in the damping force.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Fahrzeug der eingangs genannten Art zu schaffen, dessen Dämpfungseinrichtung ruckfrei arbeitet.The invention is therefore based on the object of providing a vehicle of the type mentioned at the beginning, the damping device of which operates smoothly.

Die erfindungsgemäße Lösung besteht darin, daß die zusammenwirkenden Anschlagflächen der Stützarme mit ineinandergreifenden, eine seitliche Relativbewegung derselben verhindernden Erhöhungen und Vertiefungen versehen sind.The solution according to the invention is that the cooperating stop surfaces of the support arms with interlocking, a lateral relative movement of the same preventing increases and Depressions are provided.

Durch diese Maßnahmen konnten die ruckartigen Ände- rungen der Dämpfungskraft vermieden werden. Diese beruht nämlich nicht, wie man zunächst dachte, auf einem fehlerhaften Arbeiten der mit den Stützarmen verbundenen Dämpfungshydraulik sondern darauf, daß beim Auftreten von unterschiedlichen Dämpfungskräften an den miteinander verbundenen Armen seitliche Relativbewegungen an den Anschlagflächen auftraten, die durch die erfindungsgemäße Ausbildung verhütet werden.These measures jerky Ä could nde- conclusions of the damping force can be avoided. This is because, as was initially thought, not based on faulty operation of the damping hydraulics connected to the support arms, but rather on the fact that when different damping forces occurred on the interconnected arms, lateral relative movements occurred on the stop surfaces, which are prevented by the inventive design.

Damit die Anschlagflächen trotz der Erhöhungen und Vertiefungen noch einwandfrei aufeinander abwälzen können, sind die Erhöhungen und Vertiefungen auf den in an sich bekannter Weise konvex ausgebildeten Anschlagflächen zweckmäßigerweise als Verzahnung ausgebildet.So that the abutment surfaces can still roll perfectly against one another despite the elevations and depressions, the elevations and depressions are expediently designed as teeth on the convexly formed abutment surfaces.

Damit die Erhöhungen und Vertiefungen richtig ineinandergreifen, wenn die Anschlagflächen nach einer Lösung voneinander wieder zusammenkommen, sind die oben erwähnten Anschläge vorgesehen, die dafür sorgen, daß die Stützarme mit den daran befindlichen Anschlagflächen im gelösten Zustand eine definierte Stellung einnehmen.So that the elevations and depressions interlock properly when the stop surfaces come together again after a solution from one another, the abovementioned stops are provided, which ensure that the support arms with the stop surfaces located thereon assume a defined position in the released state.

Wenn die Anschlagplatten nicht ständig in gegenseitigem Kontakt gehalten sind, sondern sich bei einer Knickung des Gelenks in dem anderen Richtungssinn sich voneinander lösen, ist es vorteilhaft, die voneinander gelösten Arme durch Anschläge eingriffsbereit zu halten.If the stop plates are not kept in constant contact with each other, but if they separate from each other when the joint is bent in the other direction, it is advantageous to keep the arms that are detached from one another ready for engagement by stops.

Die Erfindung wird im folgenden näher unter Bezugnahme auf das in der Zeichnung schematisch dargestellte Ausführungsbeispiel beschrieben. Darin zeigen:

  • Figur 1 eine schematische Draufsicht auf den Gelenkbereich bei Geradeausfahrt und
  • Figur 2 eine entsprechende Draufsicht bei Kurvenfahrt.
The invention is described in more detail below with reference to the embodiment shown schematically in the drawing. In it show:
  • Figure 1 is a schematic plan view of the joint area when driving straight ahead and
  • Figure 2 is a corresponding top view when cornering.

Bei 1 und 2 sind der vordere und der hintere Fahrzeugteil angeordnet. Ihre Fahrgestell-e strecken einander Fortsätze 3, 4 entgegen, die durch das Gelenk 5 mit vertikaler Achse verbunden sind, so daß sie bei einer Linkskurve sich beispielsweise gemäß Fig. 2 einstellen können. Einzelheiten der Fahrzeuganordnung und der am Gelenk vorgesehenen Dämpfungseinrichtung kann man der deutschen Offenlegungsschrift 24 2o 2o3 entnehmen.At 1 and 2, the front and rear vehicle parts are arranged. Your chassis-e extend towards each other extensions 3, 4, which are connected by the hinge 5 to the vertical axis, so that they can be adjusted, for example, as shown in FIG. 2 on a left turn. Details of the vehicle arrangement and the damping device provided on the joint can be found in German Offenlegungsschrift 24 2o 2o3.

Auf jeder Gelenkseite ist ein Paar von Stützarmen 6, 7 vorgesehen, die durch hydraulische Einrichtungen 10, 11 gegeneinander gespannt werden. Selbstverständlich könnten aber auch andere Einrichtungen als hydraulische vorgesehen sein, um an den Armen 6, 7 eine Kraft zu erzeugen, die das Gelenk gegenüber einer übermäßigen oder zu raschen Knickung abstützt. Die Arme 6, 7 sind bei 19, 2o an den Fortsätzen 3, 4 angelenkt. Die Anlenkpunkte liegen exentrisch zu dem Gelenk 5. Die Anlenkachsen 19 und 2o sowie die Gelenkachse 5 sind zueinander parallel und in Betriebsstellung im wesentlichen vertikal.On each side of the joint, a pair of support arms 6, 7 which are clamped against each other by hydraulic means 1 0,. 11 Of course, other means than hydraulic could also be provided in order to generate a force on the arms 6, 7 which supports the joint against excessive or rapid buckling. The arms 6, 7 are articulated at 19, 2o on the extensions 3, 4. The articulation points are eccentric to the joint 5. The articulation axes 19 and 20 and the articulation axis 5 are parallel to one another and essentially vertical in the operating position.

Die Stützarme 6, 7 tragen an ihren Enden starr mit mit den Armen verbundene Druckplatten, die die Anschlagflächen 12, 13, bilden, die mit gewellten, ineinandergreifenden Zahnungen 16, 17 versehen sind. Der Zahneingriff sorgt für einen gleichmäßigen und gleichbleibenden Eingriff selbst dann, wenn die durch die Einrichtungen 10, 11 verursachten Stützkräfte oder die an den Anlenkpunkten 19, 2o auftretenden Reibungen unterschiedlich sein sollten. Die Arme sind zusätzlich zu der Dämpfungskraft, die hydraulisch in den Zylindern 10, 11 erzeugt werden kann, ständig von einer nachgiebigen Rückführkraft beaufschlagt, die den Winkel zwischen den Armen und der Fahrzeuglängsachse zu verkleinern bestrebt ist. Diese Rückstellkraft kann auch hydraulisch in den Zylindern 10, 11 erzeugt werden.The support arms 6, 7 carry at their ends rigidly connected to the arms pressure plates that the An Form faces 12, 13, which are provided with corrugated, interlocking teeth 16, 17. The toothed engagement provides a uniform and constant engagement, even if the should be different by the means 1 0, 11 supporting forces caused or the friction occurring at the articulation points 19, 2o. In addition to the damping force which can be generated hydraulically in the cylinders 10, 11, the arms are constantly subjected to a resilient return force which tends to reduce the angle between the arms and the longitudinal axis of the vehicle. This restoring force can also be generated hydraulically in the cylinders 10, 11.

Bei Geradeausfahrt liegen die Anschlagflächen 12, 13 aneinander an (Fig. 1). Bei Kurvenfahrt vergrößert sich der Winkel zwischen den auf der Kurveninnenseite liegenden Armen und der Fahrzeuglängseinrichtung (Fig. 2 links), während sie sich auf der anderen Seite (Fig. 2 rechts) voneinander lösen. In diesem voneinander gelösten Zustand wird die Stellung der Stützarme durch Anschläge 14, 15 bestimmt, an die sich die Arme unter der Rückführkraft anlegen. Sie nehmen dann gleiche Winkel zur Fahrzeuglängsachse ein, wenn sie gleich lang sind. Jedenfalls haben ihre Anschlagflächen dann einen gleichen Abstand von der Gelenkachse 5. Die Anschläge 14, 15 sind also derart positioniert, daß die Zähne der Anschlagflächen 12, 13 wieder den richtigen Eingriff finden, wenn die Fahrzeugteile in die Geradeausstellung zurückkehren. Die Verzahnung kann gegebenenfalls auf einen Zahn in der einen Druckplatte und auf 2 Zähne in der damit zusammenwirkenden Gegendruckplatte reduziert werden.When driving straight ahead, the abutment surfaces 12, 13 abut one another (FIG. 1). When cornering, the angle between the arms lying on the inside of the curve and the vehicle longitudinal device (FIG. 2 on the left) increases, while on the other side (FIG. 2 on the right) they separate from one another. In this released state, the position of the support arms is determined by stops 14, 15, against which the arms rest under the return force. They then take the same angle to the vehicle's longitudinal axis if they are of the same length. In any case, their stop surfaces are then at an equal distance from the articulation axis 5. The stops 14, 15 are thus positioned such that the teeth of the stop surfaces 12, 13 find the correct engagement again when the vehicle parts return to the straight-ahead position. The toothing can optionally be reduced to one tooth in one pressure plate and to 2 teeth in the counterpressure plate interacting with it.
