Description
Elektronisch gesteuerte hydraulische Nachlauflenkung für Fahrzeuge: Beschreibung Es sind hydraulisch betätigte Lenkungen bekannt, bei denen der Lenkeinschlag z.B. eines Sattelaufliegers zur Sattelzugmaschine zur Betätigung von Hydraulikzylindern benutzt wird, die ihrerseits das verdrängte Druckmedium über Rohrleitungen zu den Lenkzylindern der Hinterachsen fördern.Electronically controlled hydraulic self-steering for vehicles: Description There are hydraulically operated steering systems known in which the steering angle E.g. a semi-trailer to the tractor unit to operate hydraulic cylinders is used, in turn, the displaced pressure medium via pipelines to the Promote steering cylinders of the rear axles.
Hierbei wirkt die Hydraulik also lediglich als Ersatz für Lenkgestänge oder Lenkseile, mit dem Vorteil, daß die Obertragung der Lenkkräfte baulich einfach auszuführen ist.In this case, the hydraulics only act as a replacement for the steering linkage or steering cables, with the advantage that the transmission of the steering forces is structurally simple is to be carried out.
Der Lenkeinschlag der Hinterachsen erfolgt dabei stets gleichzeitig mit dem Lenkeinschlag z,B. des Sattelaufliegers auf der Sattelzugmaschine. Dies aber hat zur Folge, daß die Räder der Hinterachsen zunächst entgegen der Lenkrichtung der Zugmaschine gestellt werden, und das Fahrzeugende stark entgegengesetzt der gewollten Richtung ausschert.The steering angle of the rear axles always takes place simultaneously with the steering angle z, B. of the semi-trailer on the tractor unit. this but has the consequence that the wheels of the rear axles initially counter to the steering direction the tractor, and the end of the vehicle strongly opposed to the direction.
Es std deshalb sogen. Nachlauflenkungen entwickelt worden, bei denen das Lenken der Hinterachsen erst nach einem Lenkeinschlag des Sattelaufliegers über einen LenkKranz der Hinterachspartie erzwungen wird. Mit diesem Lenkprinzip, da mit der Bodenhaftung der Räder der Hinterachsen arbeitet, konnte das Ausscheren unter Beibehaltung der Spurläufigkeit wesentlich vermjindert werden. Dieses Prinzip ist aber rein mechanisch und läßt sich nur dort anwenden, wo die erforderliche Anlenkung der Hinterachspartie am Fahrzeugrahmen baulich möglich ist.It std therefore sucked. Self-steering systems have been developed where the steering of the rear axles only after the semitrailer has turned the steering wheel a steering ring of the rear axle is forced. With this steering principle, there works with the traction of the rear axle wheels, the swerve could can be significantly reduced while maintaining the tracking. This principle but is purely mechanical and can only be used where the necessary linkage the rear axle section on the vehicle frame is structurally possible.
Aufgabe der Erfindung ist es deshalb, eine Lenkung zu schaffen, die zwar in Abhängigkeit von dem Lenkeinschlag des Aufliegers zur Zugmaschine gesteuert wird, aber die Vorteile der Nachlauflenkung trotzdem beinhaltet.The object of the invention is therefore to create a steering system that controlled depending on the steering angle of the semitrailer to the tractor is, but still includes the advantages of self-steering.
Abb. I zeigt schematisch ein Ausführungsbeispiel des Erfindungsgedankens an einem Sattelkraftfahrzeug.Fig. I shows schematically an embodiment of the inventive concept on an articulated vehicle.
Mit der Sattelzugmaschine (1) ist der Sattelauflieger (2) durch die Sattelkupplung (3) horizontal drehbar verbunden.With the tractor unit (1), the semi-trailer (2) is through the Fifth wheel coupling (3) horizontally rotatably connected.
Die Hinterachspartien (4) sind an dem Rahmen des Sattelaufliegers (2) in den Punkten (5) ebenfalls horizontal drehbar angelenkt, Hydraulikzylinder (6), die durch Magnetventile (71 gesteuert werden, dienen zur horizontalen Drehbewegung der Hinterachspartie (4) Auf dem Königszapfen der Sattelkupplung (3) ist ein Potentiometer (8) in der Art angebracht, daß es mit dem Lenkeinschlag des Sattelaufliegers (2) gegenüber der Sattelzugmaschine (1) gedreht wird. Auf der Hinterachspartie (4) sind 2 weitere Potentiometer (9u.io) ebenfalls so angebracht, daß sie mit der horizontalen Drehbewegung gegenüber dem Rahmen des Sattelaufliegers (2) gedreht werden.The rear axle parts (4) are on the frame of the semi-trailer (2) also pivoted horizontally in points (5), hydraulic cylinder (6), which are controlled by solenoid valves (71, are used for horizontal rotary movement the rear axle section (4) There is a potentiometer on the king pin of the fifth wheel coupling (3) (8) attached in such a way that it is with the steering angle of the semi-trailer (2) is rotated in relation to the tractor unit (1). Are on the rear axle (4) 2 more potentiometers (9u.io) also attached in such a way that they work with the horizontal Rotary movement relative to the frame of the semi-trailer (2) are rotated.
Ehe Elektronikeinheit (11) vergleicht nun die Signale der Potentiometer (9 u.io) zum Potentiometer (8) und gibt den Magnetventilen (7) die erforderlichen Steuerimpulse zur Betätigung der Hydraulikzylinder (6). Mit dieser Elektronik lassen sich nun je nach Länge des Fahrzeuges die Winkelstellungen der Hinterachspartien so einstellen, daß die Kurvenläufigkeit des Sattelzuges stets gewährleistet ist.Before the electronic unit (11) now compares the signals from the potentiometers (9 u.io) to the potentiometer (8) and gives the solenoid valves (7) the necessary Control pulses for actuating the hydraulic cylinders (6). Leave with this electronics The angular positions of the rear axle sections are now depending on the length of the vehicle Adjust so that the trailer truck can always turn around corners.
Durch einen weiteren Potentiometer (12), der im Fabrerhaus angeordnet ist und von Hand betätigt werden kann ist es möglich, jeden beliebigen Lenkeinschlag der Hinterachspartien, unabhängig von Lenkeinschlag des Sattelaufliegers (2) zur Sattelzugmaschine (1), zu erreichen.By another potentiometer (12), which is located in the factory is and can be operated by hand, it is possible to use any steering angle the rear axle parts, regardless of the steering angle of the semi-trailer (2) for Tractor unit (1) to reach.
Dadurch können Rangierbewegungen auch auf engstem Raum durchgeführt werden, zumal dieses Prinzip folgerichtige Lenkung auch bei Rückwärtsfahrt gewährleistet.This enables maneuvering movements to be carried out even in the smallest of spaces especially since this principle ensures consistent steering even when reversing.
