Starrachse mit hydropneumatischen Federbeinen in Nutzfahrzeugen BeschreibungRigid axle with hydropneumatic suspension struts in commercial vehicles Description
Die Neuerung bezieht sich auf eine Starrachse mit hydropneumatischen Federbeinen in Nutzfahrzeugen.The innovation relates to a rigid axle with hydropneumatic suspension struts in commercial vehicles.
Bei Fahrzeugen mit Starrachsen und hydropneumatischen Federbeinen ergibt sich aus kinematischen Gründen, daß das Einfedern der Räder bei Verschränkung einen viel größeren Radkasten beansprucht als bei Paralleleinfederung, d.h., daß entweder der Radkasten bei Paralleleinfederung nicht genutzt wird oder die Paralleleinfederung bei vorgegebenen kleinen Radkasten reduziert werden muß.In vehicles with rigid axles and hydropneumatic spring struts, for kinematic reasons, the deflection of the wheels during articulation requires a much larger wheel housing than during parallel deflection, i.e. that either the wheel housing is not used during parallel deflection or the parallel deflection must be reduced given the small wheel housing.
Der Neuerung liegt die Aufgabe zugrunde, die Radkästen optimal auszunutzen.The innovation is based on the task of making optimal use of the wheel arches.
Dies wird neuerungsgemäß dadurch erreicht, daß der Mind estfrei raum zwischen den rahmenfesten Radkasten und den ihnen zugehörigen, mit der Starrachse verbundenen Rädern bei verschränkender Einfederung, geregelt über variable Anschläge, nicht größer ist als bei maximaler Paralleleinfederung. In Ausgestaltung der Neuerung ist an der Starrachse, beiderseits der Fahrzeuglängsmittelebene und in gleichem Abstand zu ihr je ein Sensor zur Erfassung der unterschiedlichen Rahmenhöhe bei Verschränkung angeordnet. Die entsprechenden Meßwerte werden von einem Steuergerät ausgewertet, dessen Signale auf zwischen Federspeichern und hydropneumatischen Federbeinen angeordneten Sperrdrosselventilen geschaltet sind. Bei Erreichen eines vorgegebenen Grenzwertes ist die Verbindung zwischen den Federspeichern und den hydropneumatischen Federbeinen gesperrt. Solcherart können unnötig große Radkasten und Federbeine vermieden werden.This is achieved in accordance with the innovation by ensuring that the minimum free space between the wheel housings fixed to the frame and the wheels connected to them, which are connected to the rigid axle, is not greater during deflection, controlled by variable stops, than during maximum parallel deflection. In the innovation, a sensor is arranged on the rigid axle, on both sides of the vehicle's longitudinal center plane and at the same distance from it, to record the different frame heights during deflection. The corresponding measured values are evaluated by a control unit, the signals of which are switched to blocking throttle valves arranged between the spring accumulators and the hydropneumatic spring struts. When a predetermined limit is reached, the connection between the spring accumulators and the hydropneumatic spring struts is blocked. In this way, unnecessarily large wheel housings and spring struts can be avoided.
Die Neuerung ist in einem Ausführungsbeispiel dargestellt. Die einzige Figur zeigt eine Schemaskizze einer Starrachsenaufhängung.The innovation is shown in an example. The only figure shows a schematic sketch of a rigid axle suspension.
An der Starrachse 6 sind die Räder 7 befestigt, deren oberer Teil von einem Radkasten 8 umgeben ist. Zwischen Rahmen 9 und Starrachse 6 sind beiderseits der Längsmittelebene hydropneumatische Federbeine 2 gelenkig angebunden. Ebenso beiderseitig der Längsmittelebene und in gleichem Abstand zu ihr sind Senso-The wheels 7 are attached to the rigid axle 6, the upper part of which is surrounded by a wheel housing 8. Hydropneumatic spring struts 2 are connected in an articulated manner between the frame 9 and the rigid axle 6 on both sides of the longitudinal center plane. Sensors are also attached on both sides of the longitudinal center plane and at the same distance from it.

ren 5 angeordnet. Diese messen bei Verschränkung des Rahmens 6 ihren Wegunterschied, der dann das Maß der Verschränkung bedeutet, das in ein Steuergerät 3 eingegeben wird und dort mit einem maximalen Grenzwert abgeglichen wird. Ist der maximale Grenzwert erreicht, so werden die zwischen den Federspeichern 1 und den hydropneumatischen Federbeinen 2 angeordneten Sperr-Drosselventile 4 geschlossen, wodurch einer weiteren Verschränkung der Radkästen entgegengewirkt wird.ren 5 are arranged. These measure their path difference when the frame 6 is twisted, which then represents the degree of twisting, which is entered into a control unit 3 and compared there with a maximum limit value. If the maximum limit value is reached, the blocking throttle valves 4 arranged between the spring accumulators 1 and the hydropneumatic spring struts 2 are closed, which counteracts further twisting of the wheel arches.
