Description
Achsaggregat mit mindestens zwei Achsen, insbesondere für mehrachsige Sattelauflieger für SattelschlepperfahrzeugeAxle assembly with at least two axles, especially for multi-axle semi-trailers for articulated vehicles
Die Erfindung bezieht sich auf ein Achsaggregat mit mindestens zwei Achsen, insbesondere für mehrachsige Sattel auflieger für Sattelschlepperfahrzeuge, bei dem die Räder einer oder mehrerer Achsen von der Fahrbahn abhebbar sind, so daß sich nur die Räder einer Dauerlaufachse in direktem Kontakt mit derselben befinden.The invention relates to an axle assembly with at least two axles, in particular for multi-axle semitrailers for articulated lorries where the wheels of one or more axles can be lifted off the road, so that only the wheels of an endurance axle are in direct Contact with the same.
Bei mehrachsigen Lastfahrzeugen, vor allem Sattelaufliegern, ist es bekannt, zur Schonung der Reifen bei Leerfahrten mindestens eine Achse liftbar vorzusehen9 d.h. sie entweder mechanisch, pneumatisch oder hydraulisch so aus der Normallage zu bringen, daß der Fahrbahnkontakt aufgehoben wird. Dies bedingt natürlich eine unterschiedliche Achskonstruktion, die ziemlich aufwendig ist.In multi-axis load vehicles, especially semi-trailers, it is known to provide at least one axle liftable to protect the tire when running empty 9 they ie, either mechanically, pneumatically or hydraulically to bring so from the normal position that the road contact is canceled. Of course, this requires a different axle construction, which is quite complex.
Der Erfindung liegt die Aufgabe zugrunde, ein Achsaggregat der genannten Art zu schaffen, welches konstruktiv in relativ einfacher Weise die Aufhebung und Wiederherstellung des Kontakts zwischen Rädern und Fahrbahn ermÖglicKt.The invention is based on the object of creating an axle assembly of the type mentioned, which is structurally in relative enables the removal and re-establishment of contact between the wheels and the road surface in a simple manner.
;■'■.·■ Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Dauerlaufachse über ein in an sich bekannter Weise betätigbares Spreizelement in Richtung Fahrbahn aiis ihrer normalen Lage heraus bewegbar ist, derart, daß der Abstand a von der Achsmitte zur Ladefläche als Bezugsebene um den Betrag χ vergrößert und die anderen Achsen über Koppelglieder, die mit der Dauerlaufachse verbunden sind, von der Fahrbahn in Richtung Ladefläche um den Betrag"y anhebbar sind, wobei y so groß ist, daß der Kontakt zur Fahrbahn aufgehoben ist.; ■ '■. · ■ This object is achieved according to the invention in that the Continuous running axis via a spreading element that can be actuated in a manner known per se in the direction of the roadway as its normal Position is movable out, such that the distance a from the center of the axis to the loading area as a reference plane by the amount χ enlarged and the other axles via coupling links that are connected to the endurance axle from the road in Can be raised in the direction of the loading area by the amount "y, where y is so large that contact with the roadway is canceled.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Merkmalen der Ansprüche 2 bis 5. ·- ■■ Advantageous developments of the invention result from the features of claims 2 to 5. · - ■■
Nachstehend ist ein bevorzugtes Ausführungsbeispiel der Erfindung mit bezug auf die schematischen Zeichnungen näher beschrieben; es zeigen:Below is a preferred embodiment of FIG Invention described in more detail with reference to the schematic drawings; show it:
Fig. 1 eine Seitenansicht eines zweiachsigen Achsaggregats im Normalbetrieb - beide Achsen auf der Fahrbahn -;1 shows a side view of a two-axle axle assembly in normal operation - both axles on the roadway -;
Fig. 2 dasselbe Achsaggregat wie in Fig. 1, jedoch mit abgesenkter Lauf- und angehobener Hubachse;FIG. 2 shows the same axle assembly as in FIG. 1, but with a lowered one Running and raised lifting axis;
Fig. 3 eine Seitenansicht eines dreiachsigen Achsaggregat im Normalbetrieb - alle Achsen auf der Fahrbahn -;3 shows a side view of a three-axle axle assembly in normal operation - all axles on the roadway -;
Fig. A dasselbe Achsaggregat wie in Fig. 3, jedoch mit abgesenkter mittiger Laufachse und angehobenen Hubachsen. . 'Fig. A shows the same axle assembly as in Fig. 3, but with the central running axle lowered and the lifting axles raised. . '
Zweiachsige Achsaggregate 1 sind im Normalfall so aufgebaut, daß auf einer mittleren Stutzachse 2, die an der Unterseite der Ladefläche 3 mittels Lagerböcke 4 angebracht sind, ein Federpaket 5, welches zur Federung eines Sattelaufliegers dient, mittig daran befestigt ist. An den äußeren Enden 6 des Federpakets 5 sind die eigentlichen Laufachsen 7 mit der Bereifung 8 angebracht.Two-axis axle assemblies 1 are normally constructed so that on a central support axis 2, which is on the Underside of the loading area 3 are attached by means of bearing blocks 4, a spring assembly 5, which is used for the suspension of a Semi-trailer is used, is attached in the middle. At the outer ends 6 of the spring assembly 5 are the actual Running axles 7 with the tires 8 attached.
Für den reifenschonenden Betrieb - z.B. bei Leerfahrten kann über ein Spreizelement 9, das hydraulisch, mechanisch oder wie hier z.B. pneumatisch betätigt wird, die rechte Achse in Richtung Fahrbahn 10 gedrückt werden. Dabei vergrößert sich der Abstand a von der Achsmitte um den Wert x. Das Federpaket 5 bewirkt über die Stützachse 2 ein Anheben der zweiten Achse um den Betrag y, der so groß sein muß, daß eine sog. Hubachse 11 nicht mehr mit der Fahrbahn-in Berührung steht. Zur Verhinderung eines Überbebens der Dauerlaufachse 12 ist bei der Hubachse 11 ein Anschlag 13 vorgesehen.For tire-friendly operation - e.g. when driving empty, a spreader element 9, which is hydraulic, mechanical or as here e.g. pneumatically operated, the right axis is pushed in the direction of the lane 10. Included the distance a from the center of the axis increases by the value x. The spring assembly 5 effects the support axis 2 a lifting of the second axis by the amount y, which must be so large that a so-called lifting axis 11 is no longer with the road is in contact. To prevent a A stop 13 is provided on the lifting axis 11 if the continuous running axis 12 is overturned.
Bei dreiachsigen Achsaggregaten 14 sind die mittlere Achse als Dauerlaufachse 15 und die beiden anderen Achsen als Hubachsen 16,17 ausgebildet. Die Dauerlaufachse 15 ist dabei zwischen zwei Lagerböcke 18 an als Koppelglieder ausgebildeten Ausgleichsschwingen 19 mit ihrem Federpaket 20 befestigt. Die Ausgleichsschwingen 19 können dabei in den Lagerböcken 18 um Achsen 21 kippen. Die Hubachsen 16,17 sind ebenfalls an Federpaketen 22 befestigt, von denen ein Ende fest je in einem Bock 23 und das andere Ende beweglich in der zugehörigen Ausgleichsschwinge 19 gelagert ist.In the case of three-axle axle assemblies 14, the middle ones are Axis designed as a continuous axis 15 and the other two axes as lifting axes 16,17. The endurance axis 15 is between two bearing blocks 18 on compensating rockers 19 designed as coupling links with their spring assembly 20 attached. The compensating rockers 19 can tilt about axes 21 in the bearing blocks 18. the Lifting axes 16, 17 are also attached to spring assemblies 22, one end of which is fixed in a bracket 23 and the other end is movable in the associated compensating rocker 19 is stored.
Durch das über der Dauerlaufachse 15 angeordnete Spreizelement 14 kann bei Schonbetrieb diese Achse um den Betrag χ über den Normalabstand a in Richtung Fahrbahn 10By means of the spreading element arranged above the continuous running axle 15 14 can this axis by the amount χ over the normal distance a in the direction of the roadway 10
gedrückt werden. Dadurch werden aber mittels der Ausgleichsschwingen 19 die beweglichen Enden der Federpakete 22 der Hubachsen 16,17 nach oben bewegt. Dies bewirkt, daß die beiden Achsen zugleich je um den Wert y angehoben werden und dadurch keinen Kontakt mehr mit der Fahrbahn 10 haben.be pressed. As a result, however, the movable ends of the spring assemblies 22 of the compensating rockers 19 Lifting axes 16,17 moved upwards. This causes the two Axes are simultaneously raised by the value y and thus no longer have any contact with the roadway 10.
Durch Weglassen der vorderen bzw. hinteren Hubachse kann aus einem dreiachsigen ein zweiachsiges'(nicht dargestelltes) Achsaggregat gemacht werden, wobei die Beaufschlagung wie oben beschrieben erfolgt. Der einzige Unterschied dabei ist der, daß das Federpaket der Dauerlaufachse nur wie ein einarmiger Hebel nach unten gedruckt wird.By omitting the front or rear lifting axis, a three-axis one can be converted into a two-axis one (not shown) Axle assembly can be made, the application being carried out as described above. The only difference is that the spring package of the endurance axle is only pushed down like a one-armed lever.
