Description

Die Erfindung betrifft -ein selbsteinspurendes Doppelachsaggregat, welches für Dreiachsanhänger verwendet werden kann. Die Erfindung sei an Hand der Zeichnung erläutert.The invention relates to a self-tracking double axle unit, which can be used for three-axle trailers. The invention is based on the Drawing explained.

Abb. i zeigt das Aggregat in vertikalem Schnitt durch die Federaufhängung, Abb. 2 eine Draufsicht zu Abb. i, Abb. 3 einen vertikalen Schnitt durch die Mitte im Aufhängepunkt der einspurenden Achse,' Abb. 4 eine Draufsicht der einspurenden Achse im eingeschlagenen Zustand und Abb. 5 einen Lenkplan des Dreiachsanhängers (Draufsicht).Fig. I shows the unit in a vertical section through the spring suspension, Fig. 2 is a plan view of Fig. I, Fig. 3 is a vertical section through the middle at the suspension point of the engaging axle, Fig. 4 is a top view of the engaging axle Axle in the turned state and Fig. 5 a steering plan of the three-axle trailer (Top view).

Die Erfindung ist dadurch gekennzeichnet, daß bei einem bekannten starren Doppelachsaggregat die hintere Achse drehbar in einem Drehpunkt b angelenkt ist. Die Federtraversen c für die hintere Federaufhängung sind so ausgebildet, daß die einspurende, angelenkte Achse a sich innerhalb der Federtraversen c bewegen kann und bei einem bestimmten Einschlagwinkel ß anschlägt. Die Lastübertragung erfolgt von der mit dem Fahrzeugrahmen verbundenen Systemachse d über die vier Federn f direkt auf beide Laufachsen a und g, wobei die einspurende Achse a während der Lastübernahme innerhalb der Federtraverse c gleiten kann. Der Drehpunkt b kann in der Mitte der Achse sein; besser ist es jedoch, den Drehpunkt b um den Abstand x nach vorn zu verlegen, damit ein natürliches Nachlaufen der Achse a gewährleistet ist. Die Abstützung des Drehpunkts b erfolgt durch eine geeignete Zuggabel in Dreieckkonstruktion h, welche mit der Systemachse d drehbar verbunden ist, damit die Du:rchfederung der Systemachse d unbehindert bleibt. Um ein unerwünschtes Ausschwingen der einspurenden Achse durch Fahrbahnstöße bei Straßenunebenheiten zu verhindern, wirkt eine entsprechende Dämpfung der Bewegungen der Achse a entgegen. Die Dämpfung kann erzielt werden durch eine Blattfeder i oder durch Stoßdämpfer oder Schraubenfedern k oder gleichzeitig durch alle Teile zusammen. Die Dämpfung wird so eingestellt, daß kurz auftretende Stöße abgefangen werdeh und ein Ausschwingen verhindert wird, während bei länger anhaltender, gleichmäßig wirkender Kraft ein Nachgeben möglich ist.The invention is characterized in that in a known rigid double axle assembly, the rear axle is articulated rotatably in a pivot point b. The spring crossbars c for the rear spring suspension are designed so that the engaging, articulated axis a can move within the spring crossbars c and strikes at a certain steering angle β. The load is transferred from the system axle d connected to the vehicle frame via the four springs f directly to both running axles a and g, whereby the engaging axle a can slide within the spring traverse c during the load transfer. The pivot point b can be in the middle of the axis; however, it is better to move the pivot point b forward by the distance x so that the axis a can follow naturally. The pivot point b is supported by a suitable drawbar in a triangular construction h, which is rotatably connected to the system axis d so that the springing of the system axis d remains unhindered. In order to prevent unwanted swinging out of the engaging axle due to bumps in the road on uneven roads, a corresponding damping of the movements of the axle a counteracts. The damping can be achieved by a leaf spring i or by shock absorbers or coil springs k or simultaneously by all parts together. The damping is set in such a way that brief impacts are absorbed and swinging is prevented, while giving way is possible with longer lasting, uniformly acting force.

Die Erfindung hat den Vorteil, d'aß sich die hinteren Räder selbständig, ohne jede zwangsläufige Steuerung, in der Kurve einstellen können, wobei durch den vorgelagerten Drehpunkt b zur Achse a ein Einlaufen der Achse a nach innen verhindert wird. Dadurch ist es möglich, den Federabstand y groß auszubilden, was eine günstige Standsicherheit für das Fahrzeug bedeutet. Für Rückwärtsfahrt kann die einspurende Achse a durch einen doppelseitigen Sperrhebel e arretiert werden.The invention has the advantage d'the rear wheels ate independently, can set without any positive control, in the curve, by the upstream fulcrum b to the axis a good running in the axis a to the inside is prevented. This makes it possible to make the spring spacing y large, which means favorable stability for the vehicle. For reverse travel, the engaging axle a can be locked by a double-sided locking lever e.
