Abstract

The close coupled trailer drawbar has a steering control rod (4) linking the trailer and towing unit, in the same horizontal plane as the drawbar but offset to one side of the unit. The rod is displaced when the trailer and unit are angled for cornering, with the rear end of the rod operating a steering linkage to steer the front axle wheels (3) of the trailer. The trailer is able to track in tight curves without angling the body too tightly with that of the towing unit. This increases the load space of the trailer. The steering rod is hinged on a control lever to pivot about the transverse pivot (6) of the drawbar.

Description

Anhänger für Lastkraftwagen Trailers for trucks

Die Erfindung bezieht sich auf einen Anhänger der im Oberbegriff des Patentanspruchs 1 bezeichneten Art.The invention relates to a trailer in the preamble of Claim 1 designated Art.

Ein solcher Anhänger ist in der Patentanmeldung P 30 04 885.2 vorgeschlagen worden. Der Vorteil des vorgeschlagenen Anhängers liegt darin, daß der Abstand zwischen der Rückseite eines ziehenden Lkws und der Frontseite des Anhängers reduziert und dadurch der Laderaum des gesamten Lastzugs vergrößert werden kann. Ein Nachteil der vorgeschlagenen Ausführung eines gattungsgemäßen Anhängers liegt darin, daß die Ankopplung des Drehschemels des Anhängers an das Zugfahrzeug aufwendig gestaltet ist und somit die Herstellkosten entsprechend hoch liegen.Such a trailer is proposed in patent application P 30 04 885.2 been. The advantage of the proposed trailer is that the distance between the rear of a towing truck and the front of the trailer are reduced and as a result, the loading space of the entire truck trailer can be increased. A disadvantage the proposed design of a generic trailer is that the coupling of the turntable of the trailer to the towing vehicle is complex is and thus the manufacturing costs are correspondingly high.

Aufgabe der vorliegenden Erfindung ist es, einen gattungsgemäßen Anhänger zu schaffen, der baulich einfach gestaltet ist und gegenüber herkömmlichen Anhängern, die nur eine Drehschemellenkung aufweisen, nur geringe Mehrkosten in der Herstellung verursacht.The object of the present invention is to provide a generic trailer to create that is structurally simple and compared to conventional trailers, which only have a turntable steering, only small additional costs in production caused.

Diese Aufgabe wird erfindungsgemäß durch die im Kennzeichnungsteil des Patentanspruchs 1 angegebenen Merkmale gelöst.This object is achieved according to the invention by the in the labeling part of claim 1 specified features solved.

Der erfindungsgemäße Anhänger weist alle Vorteile eines mit einer Drehschemel- und gleichzeitig mit einer Achsschenkellenkung versehenen Anhängers auf, erfordert dabei jedoch gegenüber herkömmlichen Drehschemelanhängern nur geringen zusätzlichen Herstellungsaufwand.The trailer according to the invention has all the advantages of having a A turntable and a trailer with a stub axle steering at the same time but requires only a small amount compared to conventional turntable trailers additional manufacturing effort.

In den Unteransprüchen sind vorteilhafte Ausgestaltungen der Erfindung angegeben.The subclaims contain advantageous embodiments of the invention specified.

Anhand der beigefügten Zeichnung wird ein Ausführungsbeispiel der Erfindung erläutert. In der Zeichnung zeigt: Fig. 1 einen erfindungsgemäßen Anhänger, angekoppelt an einen Lkw in Seitenansicht, schematisch, Fig. 2 die Draufsicht auf die Anordnung gemäß Fig. 1, schematisch.Based on the accompanying drawing, an embodiment of the Invention explained. The drawing shows: FIG. 1 a trailer according to the invention, coupled to a truck in a side view, schematically, FIG. 2 shows the plan view the arrangement according to FIG. 1, schematically.

In der Seitenansicht gemäß Fig. 1 ist eine achsschenkelgelenkte Vorderachse 1 eines Anhängers in üblicher Weise über einen Drehschemel mit Drehkranz 2 mit dem Fahrgestell des Anhängers verbunden. Der Drehschemel ist mittels einer Zuggabel 10, die eine Zugöse aufweist, an eine Anhängerkupplung 8 eines Lkws angekoppelt.In the side view according to FIG. 1, there is a steering knuckle-steered front axle 1 of a trailer in the usual way on a turntable with turntable 2 with the Chassis of the trailer connected. The turntable is by means of a drawbar 10, which has a towing eye, coupled to a trailer coupling 8 of a truck.

In der Ebene der Zuggabel 10 ist eine Lenkstange 4 angeordnet, mit der die Räder 3 der Vorderachse 1 zwangsgelenkt werden. Die Lenkstange 4 ist mit ihrem einen Ende 5 an einem am Drehschemel 2 schwenkbar gelagerten Zwischenhebel 15 angelenkt, mit ihrem anderen Ende 7 an der Rückseite des Rahmens eines ziehenden Lastkraftwagens. Die Anlenkung der Lenkstange 4 am Lkw erfolgt vorzugsweise in einer Kugelkupplung.In the plane of the drawbar 10, a handlebar 4 is arranged with which the wheels 3 of the front axle 1 are forcibly steered. The handlebar 4 is with one end 5 on an intermediate lever pivotably mounted on the turntable 2 15 hinged, with its other end 7 on the back of the frame of a pulling Trucks. The articulation of the steering rod 4 on the truck is preferably carried out in one Ball coupling.

Wie aus Fig. 2 ersichtlich, führt vom Zwischenhebel 15 eine zweite Lenkstange 25 zu einem Lenkhebel am Achsschenkel eines Rades 3 der Vorderachse 1, so daß eine Längsverschiebung der Lenkstange 4 eine Lenkbewegung der Vorderräder 3 bewirkt. Schließlich ist am Achsschenkel eines Vorderrades 3 noch eine Dämpfvorrichtung 9 angebracht, deren Dämpfwirkung abhängig vom Lenkeinschlagwinkel der Zuggabel 10 verringerbar sein soll.As can be seen from Fig. 2, a second leads from the intermediate lever 15 Steering rod 25 to a steering lever on the steering knuckle of a wheel 3 of the front axle 1, so that a longitudinal displacement of the handlebar 4 a steering movement of the front wheels 3 causes. Finally, there is also a damping device on the steering knuckle of a front wheel 3 9 attached, the damping effect of which depends on the steering angle of the drawbar 10 should be reducible.

Wird bei Kurvenfahrt die Zuggabel 10 um den Winkel w ausgelenkt, so wird über die Lenkstange 4 der Zwischenhebel 15 um den Winkel + i4' verschwenkt, und die Räder 3 werden so ausgelenkt, daß die Vorderachse 1 auf einen gröBeren Kurvenradius geführt wird. Dadurch verringert sich der Knickwinkel zwischen Lkw und Anhänger.If the drawbar 10 is deflected by the angle w when cornering, so the intermediate lever 15 is pivoted by the angle + i4 'via the handlebar 4, and the wheels 3 are deflected so that the front axle 1 is on a larger curve radius to be led. This reduces the articulation angle between the truck and the trailer.
