BESCHREIBUNG: Die Erfindung betrifft eine Fahrzeugachse, insbesondere für einen Perso nenkraftwagen, mit zwei an Achslenkern geführten Radträgern, an denen jeweils ein Rad befestigbar ist, und mit einem Stabilisator, der die beiden Radträger miteinander verbindet. Die nächstliegende DE 10 2004 020 073 A1 beschreibt eine Fahrzeug- Vorderachse, deren Radträger (2) über Lenker (3, 4) geführt sind. Der Stabi lisator (9) ist ohne Koppelstangen indirekt über als Lenker ausgebildete Zug oder Druckstreben (6) mit den Radträgern (2) verbunden. Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, eine Fahr zeugachse anzugeben, die wenigstens einen mit dem Stand der Technik einhergehenden Nachteil nicht oder zumindest nur vermindert aufweist. DESCRIPTION The invention relates to a vehicle axle, in particular for a passenger car, with two wheel carriers guided on axle arms, to each of which a wheel can be fastened, and with a stabilizer which connects the two wheel carriers with one another. The closest DE 10 2004 020 073 A1 describes a vehicle front axle whose wheel carriers (2) are guided by handlebars (3, 4). The stabilizer (9) is connected to the wheel carriers (2) indirectly via connecting rods designed as a pull or compression struts (6). Proceeding from this, the present invention seeks to provide a driving tool axis, which does not have at least one associated with the prior art disadvantage or at least only reduced.
Die Aufgabe wird gelöst durch die erfindungsgemäße Fahrzeugachse mit den Merkmalen des Patentanspruchs 1. Weiterbildungen und Ausgestaltun gen der Erfindung ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Erfindungsbeschreibung und den Figuren der Zeichnung. The object is achieved by the vehicle axle according to the invention with the features of claim 1. Further developments and Ausgestaltun conditions of the invention will become apparent from the dependent claims, the following description of the invention and the figures of the drawing.
Die erfindungsgemäße Fahrzeugachse ist dadurch gekennzeichnet, dass der Stabilisator direkt, d. h. ohne Koppelstangen oder Verbindungsstreben, mit den Radträgern verbunden bzw. an beide Radträger angebunden ist, was auch als direkte Stabilisatoranbindung bezeichnet werden kann. Die Radträ ger sind hierzu jeweils mit einem Gelenk bzw. Lager ausgestattet, d. h. wei- sen ein Gelenk bzw. Lager auf, an denen jeweils eines der radträgerseitigen Enden des Stabilisators befestigt bzw. gelagert ist. The vehicle axle according to the invention is characterized in that the stabilizer is connected directly, ie without coupling rods or connecting struts, to the wheel carriers or connected to both wheel carriers, which can also be referred to as a direct stabilizer connection. The wheel carriers are each equipped with a joint or bearing, ie sen a joint or bearing on which each one of the wheel carrier ends of the stabilizer is attached or stored.
Als Radträger wird eine Achskomponente bezeichnet, an der ein Fahrzeug rad sowie gegebenenfalls weitere Komponenten, wie z. B. das Radlager und der Bremssattel, befestigt werden. Als Achslenker werden gelenkig mit dem Radträger verbundene Streben bezeichnet, über die der Radträger beweg lich aufgehängt bzw. geführt ist (radführende Lenker). Bevorzugt sind pro Radträger drei bis fünf Achslenker vorgesehen. Als Stabilisator wird eine Ein richtung verstanden, die in bekannter Weise die Wankbewegungen des Fahrzeugs verringern soll, indem quasi die Einfederbewegung eines Rads über ein bspw. als Drehstab- bzw. Torsionsfeder ausgebildetes Federele ment auf das gegenüberliegende Rad übertragen wird. As a wheel carrier, an axle component is referred to a vehicle wheel and optionally other components such. B. the wheel bearing and the caliper, are attached. As wishbone articulated struts are referred to the wheel carrier, via which the wheel is suspended or moved Lich movable (wheel-guiding handlebar). Preferably, three to five wishbones are provided per wheel carrier. As a stabilizer is a direction understood A, which should reduce the rolling motion of the vehicle in a known manner by quasi the compression movement of a wheel via an example. As a torsion bar or torsion spring trained Federele element is transmitted to the opposite wheel.
Die Erfindung sieht vor, dass der Stabilisator an seinen beiden Enden direkt an den Radträgern befestigt bzw. angebunden ist. Zum einen können da durch zusätzliche Koppelstangen, Verbindungsstreben oder dergleichen ein gespart werden. Zum anderen ergeben sich gegenüber der in der DE 10 2004 020 073 A1 beschriebenen Anbindung an einen Lenker folgende Vorteile: Der Stabilisator muss bei der kinematischen Auslegung der Achse nicht oder zumindest nur in einem geringeren Maße berücksichtigt werden. Ferner können hohe Nebenfederraten sowie eine Verzwängung durch Über bestimmung vermieden werden. The invention provides that the stabilizer is attached or connected at its two ends directly to the wheel carriers. On the one hand can be saved as additional coupling rods, connecting struts or the like. On the other hand, the following advantages result over the connection to a handlebar described in DE 10 2004 020 073 A1: The stabilizer need not be considered in the kinematic design of the axle or at least only to a lesser extent. Furthermore, high secondary spring rates and a constraint can be avoided by over determination.
Zur Anbindung des Stabilisators ist jeder der beiden Radträger mit einem entsprechenden Gelenk bzw. Lager versehen, an dem jeweils eines der rad trägerseitigen Stabilisatorenden direkt befestigt ist. Ein solches Gelenk er möglicht einerseits die für die Stabilisatorfunktion erforderliche Kraft- und gegebenenfalls auch Momentübertragung und andererseits aber auch eine bedingte, insbesondere richtungsabhängige, Nachgiebigkeit, wie nachfol gend noch näher erläutert. Die Nachgiebigkeit ermöglicht z. B. einen Weg ausgleich anstelle einer Koppelstange oder dergleichen. Die Gelenke an den Radträgern können als Gummimetalllager ausgebildet sein. Ein Gummimetalllager ist ein Verbundbauteil aus Gummi oder Elasto mer und Metall, insbesondere Stahl. Bevorzugt sind die Gummimetalllager (jeweils) mit einem taillierten oder tonneauförmigen Gummiblock ausgebildet, der richtungsabhängig unterschiedliche Steifigkeiten (d. h. verschiedene Kraft-Wege-Verläufe) bzw. unterschiedliche Nachgiebigkeiten aufweist. To connect the stabilizer, each of the two wheel carrier is provided with a corresponding joint or bearing, to each of which one of the rad carrier-side stabilizer ends is directly attached. Such a joint he allows on the one hand the force required for the stabilizer function and possibly also torque transmission and on the other hand, but also a conditional, in particular direction-dependent, compliance, as explained fol lowing. The compliance allows z. As a way balancing instead of a coupling rod or the like. The joints on the wheel carriers may be formed as a rubber-metal bearing. A rubber-metal bearing is a composite component of rubber or Elasto mer and metal, especially steel. The rubber-metal bearings (in each case) are preferably formed with a waisted or tonneau-shaped rubber block which, depending on the direction, has different stiffnesses (ie different force-path profiles) or different compliances.
Die Gelenke an den Radträgern können aber auch als Kulissenführungen ausgebildet sein. Eine Kulissenführung weist eine Kulisse und einen darin geführten Kulissenstein, an dem das radträgerseitige Stabilisatorende befes tigt ist, auf. Eine Kulisse und ein darin geführter Kulissenstein oder derglei chen bilden ein Lager. Die Kulisse kann aus Metall, insbesondere Stahl, oder auch aus Kunststoff, insbesondere faserverstärktem Kunststoff, gebildet sein. Ferner kann die Kulisse (im Inneren) mit einem verschleiß- und rei bungsreduzierenden Gleitbelag ausgebildet sein. Die Kulissenführung kann mit einer Manschette, die vorzugsweise aus Gummi bzw. Elastomer gefertigt und insbesondere als Faltenbalg ausgebildet ist, abgedichtet sein. The joints on the wheel carriers can also be designed as slide guides. A slotted guide has a backdrop and guided therein sliding block on which the wheel carrier stabilizer end is taken fastened on. A backdrop and guided in it sliding block or derglei chen form a camp. The backdrop can be made of metal, in particular steel, or else of plastic, in particular fiber-reinforced plastic. Furthermore, the backdrop (inside) may be formed with a wear and friction reducing friction lining. The slotted guide can be sealed with a sleeve, which is preferably made of rubber or elastomer and in particular designed as a bellows sealed.
Die Radträger sind bevorzugt einstückige Schmiede- oder Gussteile, insbe sondere mit jeweils einer angeformten oder angegossenen Kulisse für eine Kulissenführung (wie vorausgehend erläutert). Die Schmiede- oder Gussteile sind bevorzugt spanend nachbearbeitet. The wheel carriers are preferably one-piece forgings or castings, in particular special, each with a molded or cast backdrop for a slotted guide (as previously explained). The forgings or castings are preferably post-machined.
Die Radträger können schwenkbar ausgebildet sein (sogenannte Schwenk lager), um die daran befestigten Räder lenken zu können. Die Gelenke an den Radträgern zur Anbindung des Stabilisators sind entsprechend ausge bildet. Bei der Fahrzeugachse handelt es sich bevorzugt um eine Vorderach se, insbesondere mit lenkbaren Rädern. Die Fahrzeugachse kann aber auch eine Hinterachse sein, insbesondere mit ungelenkten Rädern. The wheel carrier can be designed to be pivotable (so-called pivot bearing) in order to steer the wheels attached thereto can. The joints on the wheel carriers to connect the stabilizer are formed accordingly. The vehicle axle is preferably a front axle, in particular with steerable wheels. The vehicle axle may also be a rear axle, in particular with unguided wheels.

Fig. 1 zeigt die rechte Seite einer erfindungsgemäßen Fahrzeugachse 10, wobei es sich um eine Hinterachse handelt. Die gegenüberliegende linke Achsseite ist im Wesentlichen identisch bzw. spiegelsymmetrisch aufgebaut. Zu erkennen ist der rechte Radträger 20, der über mehrere Achslenker 30, 40, 50, 60 an einem Hilfsrahmen 70 aufgehängt ist (Einzelradaufhängung). Am Radträger 20 kann ein ungelenktes Fahrzeugrad befestigt werden. Die Fahrzeugachse 10 weist ferner einen Stabilisator 80 auf, der beidseitig mit abgewinkelten oder gekröpften Stabilisatorschenkeln ausgebildet und mit seinen radträgerseitigen Enden direkt mit den Radträgern 20 verbunden ist, wie für den rechten Radträger gezeigt (die Anbindung an den gegenüberlie genden linken Radträger ist im Wesentlichen identisch ausgebildet). Beide Radträger 20 sind hierzu mit einem Gelenk bzw. Lager 21 ausgestattet, an denen jeweils eines der radträgerseitigen Enden des Stabilisators 80 befes tigt ist. Fig. 1 shows the right side of a vehicle axle 10 according to the invention, which is a rear axle. The opposite left axis side is constructed essentially identical or mirror-symmetrical. Evident is the right wheel 20, which is suspended on a plurality of axle arms 30, 40, 50, 60 on a subframe 70 (independent suspension). On the wheel 20, a non-steered vehicle can be attached. The vehicle axle 10 further comprises a stabilizer 80, which is formed on both sides with angled or cranked stabilizer legs and connected with its Radträgerseitigen ends directly to the wheel carriers 20, as shown for the right wheel (the connection to the gegenüberlie ing left wheel is substantially identical educated). Both wheels 20 are for this purpose equipped with a joint or bearing 21, to each of which one of the wheel carrier ends of the stabilizer 80 is taken fastened.
Bei der in den Fig. 1 bis 3 gezeigten ersten Ausführungsmöglichkeit ist das Gelenk 21 als Kulissenführung ausgebildet und weist eine starr mit dem Rad träger 20 verbundene und insbesondere einstückig mit dem Radträger 20 ausgebildete Kulisse 22 auf. In der Kulisse 22 ist ein abgeflachter, mit bom bierter Ober- und Unterseite ausgebildeter Kulissenstein 24 geführt, an dem das Ende des Stabilisators 80 befestigt ist. Der Kulissenstein 24 kann auch als Zapfen mit kreisrundem Querschnitt ausgebildet sein. Ferner kann das Ende des Stabilisators 80 bereits mit einem zapfenartigen Kulissenstein 24 ausgebildet sein. Die Kulisse 22 ist innen mit einem Gleitbelag 23 versehen (zusätzlich zu einer eventuell vorgesehenen Dauerschmierung). Die Kulisse 22 kann zur Außenseite (Radseite) hin verschlossen und an der Innenseite mit einer Manschette, die das Ende des Stabilisators 80 mit einschließt, ab gedichtet sein. In the first embodiment shown in FIGS. 1 to 3, the joint 21 is formed as a slotted guide and has a rigidly connected to the wheel carrier 20 and in particular integrally formed with the wheel 20 backdrop 22 on. In the backdrop 22 is a flattened, bom bierter top and bottom trained sliding block 24 is guided, to which the end of the stabilizer 80 is attached. The sliding block 24 can also be designed as a pin with a circular cross-section. Furthermore, the end of the stabilizer 80 may already be formed with a peg-like sliding block 24. The gate 22 is internally provided with a sliding coating 23 (in addition to a possibly provided permanent lubrication). The gate 22 may be closed to the outside (wheel side) and sealed on the inside with a sleeve which includes the end of the stabilizer 80, from sealed.
Das als Kulissenführung ausgebildete Gelenk 21 ermöglicht, dass in Fahr zeughochrichtung (z-Richtung) die Einfederbewegungen am rechten Rad bzw. Radträger 20 direkt auf den Stabilisator 80 einwirken und als Moment zum gegenüberliegenden linken Rad bzw. Radträger übertragen werden und umgekehrt. Kräfte (und gegebenenfalls Momente) können jedoch nur in Fahrzeughochrichtung (z-Richtung) übertragen werden. In Fahrzeuglängs richtung (x-Richtung) und in Fahrzeugquerrichtung (y-Richtung) können kei ne Kräfte und/oder Momente übertragen werden (da sich der Kulissenstein 24 bzw. das in der Kulisse 22 gelagerte Stabilisatorende in Längs- und Quer richtung bewegen kann), sodass der Stabilisator 80 in diesen Richtungen keinen nennenswerten Einfluss auf die Fahrzeugachse 10 hat. Trained as a link guide joint 21 allows driving in the vertical direction (z-direction) the compression movements on the right wheel or wheel 20 act directly on the stabilizer 80 and transmitted as a moment to the opposite left wheel or wheel and vice versa. Forces (and possibly moments) can only be transmitted in vehicle vertical direction (z-direction). In the vehicle longitudinal direction (x-direction) and in the vehicle transverse direction (y-direction) kei ne forces and / or moments can be transmitted (since the sliding block 24 or mounted in the link 22 stabilizer end can move in the longitudinal and transverse directions) so that the stabilizer 80 has no appreciable influence on the vehicle axle 10 in these directions.
Bei der in Fig. 4 gezeigten zweiten Ausführungsmöglichkeit ist das Gelenk 21 als Gummimetalllager ausgebildet. Das Gummimetalllager weist einen zwi schen zwei Flanschen eingepressten Gummiblock 25 mit einer einvulkani sierten Metallhülse (Lagerkern), an der das Ende des Stabilisators 80 festge schraubt ist, auf. Der Gummiblock 25 ist mit einer Taillierung oder derglei chen ausgebildet, sodass das Gelenk 21 in Fahrzeughochrichtung (z- Richtung) relativ steif und in Fahrzeuglängsrichtung (x-Richtung) sowie in Fahrzeugquerrichtung (y-Richtung) relativ weich ist und somit verschiedene Kraft-Wege-Verläufe bzw. unterschiedliche Steifigkeiten aufweist. In the second embodiment shown in Fig. 4, the joint 21 is formed as a rubber-metal bearing. The rubber-metal bearing has an inter mediate two flanges pressed rubber block 25 with a einvulkani-based metal sleeve (bearing core) to which the end of the stabilizer 80 is screwed Festge on. The rubber block 25 is formed with a sidecut or derglei surfaces, so that the joint 21 in the vehicle vertical direction (z-direction) is relatively stiff and in the vehicle longitudinal direction (x-direction) and in the vehicle transverse direction (y-direction) is relatively soft and thus different force paths -Verläufe or different stiffnesses.
Beide zuvor beschriebenen Ausführungsmöglichkeiten eignen sich auch für gelenkte Räder, insbesondere an einer Vorderachse. Bei der ersten Ausfüh rungsmöglichkeit ist der Ausgleich des Lenkwinkels durch Gleitbewegungen innerhalb der Kulisse 22 gegeben, sofern die Kulisse 22 eine ausreichende Führungsbreite aufweist. Bei der zweiten Ausführungsmöglichkeit ist ein Ausgleich des Lenkwinkels durch entsprechende Gestaltung des Gummime talllagers, insbesondere des Gummiblocks 25, möglich. Both embodiments described above are also suitable for steered wheels, especially on a front axle. In the first Ausfüh approximately possibility of compensation of the steering angle is given by sliding within the gate 22, if the gate 22 sufficient Guiding width has. In the second embodiment, a compensation of the steering angle by appropriate design of Gummime talllagers, in particular the rubber block 25, possible.
