Die Erfindung bezieht sich auf eine Achsaufhängung für Fahrzeuge, mit wenigstens je einem im wesentlichen in Fahrzeuglängsrichtung verlaufenden Achslenker beidseits der Fahrzeuglängsmittelebene, welcher mit seinem vorderen Ende an einem chassisfesten Lagerpunkt angelenkt und im Abstand davon mit dem Achskörper verschweißt ist, wobei vorzugsweise ein von dem Achskörper aus jeweils nach hinten ragender Achslenkerabschnitt als unteres Lager einer Luftfeder dient, auf deren Oberseite sich das Fahrzeugchassis abstützt. Dabei ist der Achskörper üblicherweise als durchgehendes rundes einstückiges 0 Achsrohr ausgebildet. Die Fertigung derartiger Achskörper ist aufwendig und die Fahreigenschaften sind aufgrund der Starrheit und Schwere des Achskörpers verbesserungswürdig, weil das Achsrohr verhältnismäßig dickwandig sein muß.The invention relates to an axle suspension for vehicles, with at least one axle guide running essentially in the vehicle's longitudinal direction on either side of the vehicle's longitudinal center plane, which is hinged at its front end to a bearing point fixed to the chassis and welded to the axle body at a distance therefrom, with an axle guide section protruding rearward from the axle body preferably serving as the lower bearing of an air spring, on the upper side of which the vehicle chassis is supported. The axle body is usually designed as a continuous, round, one-piece axle tube. The manufacture of such axle bodies is complex and the driving characteristics are in need of improvement due to the rigidity and weight of the axle body, because the axle tube has to be relatively thick-walled.
Aufgabe der vorliegenden Erfindung ist es, eine Achsaufhängung der eingangs genannten Art so weiterzubilden, daß sie sowohl hinsichtlich ihrer Fertigung einfacher und damit kostengünstiger ist, als auch bessere Fahreigenschaften liefert.The object of the present invention is to further develop an axle suspension of the type mentioned at the beginning in such a way that it is both simpler in terms of its production and thus more cost-effective, and also provides better driving characteristics.
0 Diese Aufgabe wird erfindungsgemäß beispielsweise dadurch gelöst, daß der Achskörper von zwei in bzw. an die Achslenker geschweißten, senkrecht von diesen nach außen abstehenden koaxialen Achsstummeln und einer als vorzugsweise offenes zu den Achsstummeln koaxiales bzw. achsparalleles Profil aus0 This object is achieved according to the invention, for example, by the axle body being made up of two coaxial axle stubs welded into or onto the axle arms and projecting outwards perpendicularly from them, and a preferably open profile made of

abgekantetem Blech ausgebildeten, die Achslenker unter Bildung eines U-Stabilisators verbindenen Quertraverse gebildet ist.formed from bent sheet metal which connects the axle links to form a U-stabilizer.
Die Fertigung derartiger Achsaufhängungen ist einfach, da sowohl die verhältnismäßig kurzen kreiszylindrischen Achsstummel (durch spanabhebende Bearbeitung) als auch die Quertraverse (als abgekantetes Blech) leicht herzustellen sind. Die Achsstummel können trotz Einhaltung eines geringen Gewichts für den Achskörper verhältnismäßig dickwandig ausgebildet sein, weil die Quertraverse zwischen ihnen leicht ist.The manufacture of such axle suspensions is simple, since both the relatively short circular cylindrical axle stubs (by machining) and the cross member (as bent sheet metal) are easy to manufacture. The axle stubs can be designed with relatively thick walls despite maintaining a low weight for the axle body, because the cross member between them is light.
Die Ausbildung der gesonderten Quertraverse als offenes Profil hat ferner den Vorteil, daß es einerseits torsionsweich, andererseits aber biegesteif ausgebildet sein kann, so daß gute Fahreigenschaften sowohl bei gleichmäßiger als auch bei ungleichmäßiger Einfederung der Räder ähnlich einer Verbundfederachse gewährleistet sind.The design of the separate cross member as an open profile has the further advantage that it can be designed to be torsionally soft on the one hand, but rigid on the other, so that good driving characteristics are guaranteed both with even and uneven wheel deflection, similar to a composite spring axle.
Besonders einfach ist die Ausführung, wenn die Quertraverse als offenes C-Profil ausgebildet ist.The design is particularly simple if the cross-beam is designed as an open C-profile.
Das offene Profil der Quertraverse kann ferner der Aufnahme von Luftspeicherbehältern dienen. Daher übernimmt die Quertraverse als Festigkeitsträger die Stützfunktion für den Druck, so daß der Luftspeicherbehälter selbst nur noch die Dichtfunktion zu übernehmen braucht und zum Beispiel als Blase oder Schlauch ausgebildet sein kann. An den Stirnseiten kann die Stützfunktion für die Luftspeicherbehälter durch in das Profil der Quertraverse eingeschweißte oder eingepreßte Stützscheiben erzielt werden.The open profile of the cross-beam can also be used to accommodate air storage tanks. The cross-beam therefore acts as a strength support and supports the pressure, so that the air storage tank itself only needs to perform the sealing function and can be designed as a bladder or hose, for example. The support function for the air storage tanks can be achieved on the front sides by supporting disks welded or pressed into the profile of the cross-beam.

Achsstummel sind wenigstens durch die jeweils äußere Seitenwange, aber vorzugsweise auch durch die innere Seitenwange im wesentlichen formschlüssig hindurchgeführt und sowohl mit der äußeren Seitenwange als auch mit der inneren Seitenwange verschweißt.Axle stubs are guided essentially in a form-fitting manner through at least the outer side cheek, but preferably also through the inner side cheek, and are welded to both the outer side cheek and the inner side cheek.
Dabei kann die Verschweißung der Achsstummel mit den Achslenkern sowohl auf der Innenseite als auch auf der Außenseite der jeweiligen Seitenwange um die Achsstummel umlaufende Schweißlinien aufweisen.The welding of the axle stubs to the axle arms can have welding lines running around the axle stubs on both the inside and outside of the respective side wall.
In der Regel reicht es aus, daß die Quertraverse nur mit der jeweils inneren Seitenwange der Achslenker verbunden ist.As a rule, it is sufficient that the cross member is only connected to the inner side cheek of the axle control arm.
Weitere Ziele, Merkmale, Vorteile und Anwendungsmöglichkeiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen anhand der Zeichnung. Dabei bilden alle beschriebenen und/oder bildlich dargestellten Merkmale für sich oder in beliebiger Kombination den Gegenstand der 0 Erfindung, und zwar auch unabhängig von deren Zusammenfassung in einzelnen Ansprüchen oder deren RückbeZiehung.Further aims, features, advantages and possible applications of the invention emerge from the following description of embodiments based on the drawing. All described and/or illustrated features form the subject matter of the invention, either individually or in any combination, and this also applies independently of their summary in individual claims or their reference back.
Die einzige Figur veranschaulicht eine schematische Seitenansicht einer die Erfindung aufweisenden Fahrzeugachsaufhängung im Bereich einer Seite einer (im vertikalen Schnitt zu sehenden) Fahrzeugachse, wobei die Anordnung am gegenüberliegenden Ende des Achskörpers ebenso ausgebildet ist.The single figure illustrates a schematic side view of a vehicle axle suspension incorporating the invention in the region of one side of a vehicle axle (seen in vertical section), the arrangement at the opposite end of the axle body being designed in the same way.
Die dargestellte erfindungsgemäße Achsaufhängung für Fahrzeuge hat beidseits der Fahrzeuglängsmittelebene je einen im wesentlichen in Fahrzeuglängsrichtung verlaufenden Achslenker 1.

In the case shown, the bearing point 2 is connected to a

dem Fahrzeugchassis befestigten Lagerbock 8 vorgesehen. Der Lagerbock 8 dient dabei unter anderem auch der Abstützung der Achslenker 1 über eine Luftfeder 9 einer Achsanhebevorrichtung. Im Abstand hinter dem Lagerpunkt 2 sind die Achslenker 1 mit einem Achskörper verschweißt. Ein von dem Achskörper aus jeweils nach hinten ragender Achslenkerabschnitt 3 kann als unteres Lager einer {nicht dargestellten) Luftfeder dienen, auf deren Oberseite sich das Fahrzeugchassis abstützt.The bearing block 8 is attached to the vehicle chassis. The bearing block 8 serves, among other things, to support the axle control arms 1 via an air spring 9 of an axle lifting device. At a distance behind the bearing point 2, the axle control arms 1 are welded to an axle body. An axle control arm section 3 protruding backwards from the axle body can serve as the lower bearing of an air spring (not shown), on the top of which the vehicle chassis is supported.
Erfindungsgemäß ist der Achskörper von zwei in bzw. an die Achslenker 1 geschweißten, senkrecht von diesen nach außen abstehenden koaxialen Achsstummeln 4 und einer Quertraverse 5 gebildet. In der Zeichnung ist das innere stirnseitige Ende eines Achsstummels 4 in Draufsicht und die Quertraverse 5 im Schnitt wiedergegeben. Die Quertraverse 5 ist von einem zu den Achsstummeln 4 koaxialen bzw. achsparallelen offenen Profil aus angekantetem Blech gebildet. Dabei bildet die Quertraverse 5 mit den beiden Achslenkern 1 einen U-Stabilisator nach Art 0 einer Verbundfederachse. Aufgrund der Ausbildung der Quertraverse 5 als offenes Profil kann es einerseits torsionsweich, aber andererseits beigesteif sein, so daß vorteilhafte Fahreigenschaften sowohl bei gleichmäßigem als auch bei ungleichmäßigem Einfedern der Fahrzeugräder erreicht werden.According to the invention, the axle body is formed by two coaxial axle stubs 4 and a cross-member 5 welded into or onto the axle arms 1 and projecting outwards perpendicularly from them. The drawing shows the inner front end of an axle stub 4 in plan view and the cross-member 5 in section. The cross-member 5 is formed by an open profile made of folded sheet metal that is coaxial or axially parallel to the axle stubs 4. The cross-member 5 and the two axle arms 1 form a U-stabilizer in the style of a composite spring axle. Due to the design of the cross-member 5 as an open profile, it can be torsionally soft on the one hand, but stiff on the other, so that advantageous driving characteristics are achieved both with even and uneven compression of the vehicle wheels.
Im speziellen Fall ist die Quertraverse 5 von einem nach vorne offenen C-Profil gebildet. Dieses ist besonders einfach in der Herstellung und zweckdienlich bei der Lösung der gestellten Aufgabe. In dem offenen Profil der Quertraverse 5 ist auch noch Platz für die Aufnahme von {nicht dargestellten) Luftspeicherbehälter, welche an ihrem Umfang von dem Profil der Quertraverse 5 abgestützt werden.In this particular case, the cross-beam 5 is formed by a C-profile that is open at the front. This is particularly easy to manufacture and useful for solving the task at hand. In the open profile of the cross-beam 5 there is also space for air storage containers (not shown), which are supported on their circumference by the profile of the cross-beam 5.
Vorzugsweise weisen die Achslenker (was aus der Zeichnung nicht ersichtlich ist) jeweils zwei im Abstand voneinander im wesentlichen parallele vertikale Seitenwangen 6 auf, vonPreferably, the axle guides (which is not apparent from the drawing) each have two spaced apart essentially parallel vertical side walls 6, of which

The axle stubs 4 are guided through at least the respective outer side cheek 6 in a substantially form-fitting manner and rest with their front inner end on the outside of the inner side cheek 6. The axle stub 4 is welded both to the outer side cheek 6 of the axle link 1 and to the inner side cheek 6 by means of welding lines 7 running around the axle stub 4, preferably both on the outside and on the inside of the outer side cheek 6 and then of course also to the outside of the inner side cheek 6, against which the axle stub 4 abuts with its inner end.
