Description

BeschreibungDescription

Am vorderen Ende des Sattelaufliegerrahmens,(1) ist die Aufliegerplatte (2) auf einem Kugeldrehkranz (3) drehbar gelagert. An der Aufliegerplatte (2) ist an der Unterseite ein Mitnehmerkeil (4) angebracht.
Auf der Oberseite der Aufliegerplatte ist ein Lenksockel (5)At the front end of the semi-trailer frame (1), the trailer plate (2) is mounted on a ball bearing slewing ring (3). A driving wedge (4) is attached to the underside of the trailer plate (2).
On the top of the trailer plate is a steering base (5)

Hydraulische Zwangslenkung für 2-achsige SattelaufliegerHydraulic forced steering for 2-axle semi-trailers

Zwangslenkung von Sattelaufliegern wiesen meistens eine mecha- *· nische Übertragung der Lenkbewegungen auf, z.B. Stangenlenkung,·· Seillenkung ect.Forced steering of semi-trailers usually has a mechanical transmission of the steering movements, e.g. rod steering, cable steering, etc.

Hydraulische Zwangslenkungen üblicher Bauart haben oft ein geschwindigkeitsabhängiges Untersetzungsverhältnis, bzw. der Lenkeinschlag der Hinterachse ist auf ein bestimmtes Maß (< 45 Grad) begrenzt.Hydraulic forced steering systems of conventional design often have a speed-dependent reduction ratio, or the steering angle of the rear axle is limited to a certain amount (< 45 degrees).

Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde, eine Zwangslenkung für Sattelauflieger zu schaffen, die Lenkbewegungen der Hinterachse von mehr als 45 Grad ermöglicht. The invention specified in the protection claim is based on the problem of creating a forced steering system for semi-trailers, which enables steering movements of the rear axle of more than 45 degrees.

Dieses Problem wird durch die im Schutzanspruch aufgeführten Merkmale gelöst.This problem is solved by the features listed in the protection claim.

Mit der Erfindung wird erreicht, daß ein derart ausgestatteter Sattelauflieger äußert wendig ist. So können Ecken z.B. relativ eng umfahren werden, ohne daß man mit dem Sattelzug weit ausholen müßte.The invention makes a semi-trailer equipped in this way extremely maneuverable. Corners can be negotiated relatively tightly, for example, without having to swing the semi-trailer too far.

AusführungsbeispielExample

angebracht, an dem die 2 hydraulischen Geberzylinder (6) kolbenstangenseitig angelenkt sind. Zylinderrohrseitig sind die Zylinder am Rahmen (1) gelenkig befestigt.to which the 2 hydraulic master cylinders (6) are hinged on the piston rod side. On the cylinder tube side, the cylinders are hingedly attached to the frame (1).

Die Kolbenstangen sind über dem Lenksockel an Zapfen gelenkig geführt, so daß ein großer Drehbereich möglich ist.The piston rods are hinged to pins above the steering base, so that a large range of rotation is possible.

Eine gleiche Anordnung befindet sich an der Hinterachse des Sattelaufliegers:A similar arrangement is found on the rear axle of the semi-trailer:

2 hydraulische Nehmerzylinder (7) sind am Rahmen (1) bzw. am Lenksockel (8) gelenkig befestigt. Der Lenksockel ist fester Teil des Hinterachsrahmens (9), der auf einem Kugeldrehkranz (10) drehbar mit dem Rahmen (1) verbunden ist.2 hydraulic slave cylinders (7) are hinged to the frame (1) or to the steering base (8). The steering base is a fixed part of the rear axle frame (9), which is connected to the frame (1) on a ball bearing (10) so that it can rotate.

Die Schwenkbewegung der Sattelzugmaschine unter dem Auflieger wird über die drehbare Aufliegerplatte (2), die über,den Mitnehmerkeil (4) in Drehrichtung mit der Sattelkupplung fixiert ist, auf die Geberzylinder (6) übertragen. Durch die dadurch bewirkte Linearbewegung der Kolbenstangen der Geberzylinder (6) strömt die Hydraulikflüssigkeit auf der Druckseite der Geberzylinder (6) über die Hydraulikleitungen (11) zu den Nehmerzylindern (7). Dadurch wird eine Linearbewegung der Kolbenstangen der Nehmerzylinder (7) bewirkt.The swivel movement of the tractor unit under the trailer is transmitted to the master cylinders (6) via the rotating trailer plate (2), which is fixed to the fifth wheel coupling in the direction of rotation via the driver wedge (4). Due to the resulting linear movement of the piston rods of the master cylinders (6), the hydraulic fluid on the pressure side of the master cylinders (6) flows via the hydraulic lines (11) to the slave cylinders (7). This causes a linear movement of the piston rods of the slave cylinders (7).

Über die Anlenkung am Lenksockel wird eine Drehbewegung der Hinterachse bewirkt.The linkage on the steering base causes the rear axle to rotate.

Um unzulässig hohe Druckdifferenzen zwischen den Druckkreisen zu vermeiden sowie die Volumenänderung infolge Temperaturdifferenzen aufzufangen, ist in jedem Druckkreis ein hydropneumatischer Speicher (12) zugeordnet.In order to avoid unacceptably high pressure differences between the pressure circuits and to absorb the volume change due to temperature differences, a hydropneumatic accumulator (12) is assigned to each pressure circuit.
