Abstract

A bearing arrangement for a one-piece transverse control arm of a wheel suspension has two bearing brackets fixed to the body and arranged at a distance from one another, which define a swivel axis extending essentially in the vehicle longitudinal direction. The bearing bracket adjacent to the nearest end of the vehicle is arranged, in relation to the control arm joint assigned to it, on its side remote from this vehicle end and the control arm joint is over-mounted on this, whilst the other bearing bracket fixes the control arm joint supported on this on the vehicle body in the direction of the swivel axis. In the event of an impact force acting on this vehicle end, that part of the vehicle body forming the bearing base for the transverse control arm can also be deformed in order to neutralise impact energy, in that the bearing bracket serving for over-mounting the control arm can be displaced in the direction of the other bearing bracket.

Description

Die Erfindung betrifft eine Lageranordnung für einen ein­ teiligen Querlenker einer Radaufhängung, mit den Merkmalen des Oberbegriffes des Patentanspruches.The invention relates to a bearing arrangement for a partial wishbone of a wheel suspension, with the features the preamble of the claim.

Einteilige Querlenker von Radaufhängungen der Vorder- oder Hinterachse von Kraftfahrzeugen, die mit zwei im Abstand und fluchtend zueinander angeordneten Lenkerlagern ausge­ stattet sind, werden üblicherweise auf Lagerachsen zweier an einem Teil des Fahrzeugaufbaues, beispielsweise an einem Längsträger, im Abstand voneinander angebauten Lagerböcken gelagert, welche die Lenkerlager seitlich umgreifen und sie, bzw. den Querlenker, in Richtung der Schwenkachse gegen Verlagern sichern (vgl. DE-PS 31 45 988, Fig. 1).One-piece wishbones of wheel suspensions of the front or rear axles of motor vehicles, which are equipped with two spaced apart and aligned handlebar bearings, are usually mounted on bearing axles at a distance from each other on a part of the vehicle body, for example on a side member, at a distance from each other grasp the handlebar bearings laterally and secure them, or the wishbone, against displacement in the direction of the pivot axis (cf. DE-PS 31 45 988, Fig. 1).

Durch die einstückige Ausbildung der beiden Lenkerlager mit dem Querlenker bildet dieser im Falle eines im wesent­ lichen in Fahrzeuglängsrichtung gerichteten, einseitigen oder vollen Front- oder Heckaufpralls einen Teil der Radaufhängung, der das die Lagerböcke tragende Teil des Fahrzeugaufbaues in Fahrzeuglängsrichtung über einen durch den Abstand der beiden Lagerböcke bestimmten Abschnitt aus­ steift. Entlang dieses Abschnittes wird somit keine oder gegebenenfalls nur eine unwesentliche plastische Verformung beispielsweise eines Längsträgers erfolgen.Due to the one-piece design of the two link bearings with the wishbone in the case of an essentially Lichen, one-sided in the vehicle longitudinal direction or full front or rear impact part of the Wheel suspension, which is the part of the  Vehicle body in the vehicle longitudinal direction through a the distance between the two bearing blocks determined section stiff. There is therefore no or along this section possibly only an insignificant plastic deformation for example, a side member.

Die hieraus resultierende, reduzierte Verformungslänge des betreffenden Aufbauteils führt deshalb schon bei relativ geringen Aufprallkräften zu Verformungen von stirn- oder heckseitigen Wandteilen der Fahrgastzelle.The resulting reduced deformation length of the relevant structural part therefore already leads to relatively low impact forces to deformation of front or rear wall parts of the passenger compartment.

Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Lageranordnung mit den im Oberbegriff des Patentanspruches aufgeführten Merkmalen so zu verbessern, daß der zwischen den Anbindungsstellen der Lagerböcke liegende Bereich eines Teilstückes des Fahrzeugaufbaues im Crashfalle mit­ verformt und dadurch Aufprallenergie zusätzlich vernichtet bzw. die Fahrgastzelle noch besser geschützt werden kann.The invention is therefore based on the object Bearing arrangement with in the preamble of the claim to improve the characteristics listed so that the between the area where the pedestals are connected a part of the vehicle body in the event of a crash deformed and thereby additionally impact energy is destroyed or the passenger compartment can be protected even better.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruches gelöst.This object is achieved by the characterizing Features of the claim solved.

Die erfindungsgemäß vorgesehene fliegende Lagerung des dem nächstliegenden Fahrzeugende benachbarten Lenkerlagers stellt sicher, daß im Falle einer auf dieses Fahrzeugende einwirkenden Aufprallkraft und einer damit verbundenen Deformation des den Querlenker lagernden Teils des Fahr­ zeugaufbaues der die fliegende Lenkerlagerung übernehmende Lagerbock sich in Richtung auf den anderen Lagerbock ver­ lagern kann. Dadurch kann zwar unter Umständen die fliegende Lagerung des einen Lenkerlagers völlig aufge­ hoben werden, dafür wird aber der gesamte Bereich der aufbauseitigen Lager- und Abstützbasis des Querlenkers zur Vernichtung von Aufprallenergie in die Verformung mit einbezogen.The flying storage of the the nearest vehicle end to the adjacent steering column bearing ensures that in the event of an on this vehicle end impact force and an associated impact force Deformation of the part of the driver supporting the wishbone the superstructure that takes over the flying handlebar mounting Bearing block ver in the direction of the other bearing block can store. Under certain circumstances, this may result in the flying storage of a handlebar bearing completely open be lifted, but the entire area of  body-side support and support base of the wishbone to destroy impact energy in the deformation involved.

In der Zeichnung ist in Draufsicht eine unabhängige Radauf­ hängung, beispielsweise einer Vorderachse, in Verbindung mit einem Ausführungsbeispiel einer erfindungsgemäßen Lager­ anordnung, beispielsweise für deren unteren Querlenker, stark schematisiert, dargestellt.In the drawing, an independent wheel is in plan view suspension, for example a front axle, in connection with an embodiment of a bearing according to the invention arrangement, for example for their lower wishbones, highly schematized, shown.

Mit 10 ist ein Längsträger bezeichnet, der einen Motorraum eines Personenkraftwagens seitlich begrenzt, dessen dem Motorraum von der Fahrgastzelle trennende Stirnwand mit 12 bezeichnet ist.Denoted at 10 is a side member which laterally delimits an engine compartment of a passenger car, the end wall of which dividing the engine compartment from the passenger compartment is denoted by 12 .

Dem Längsträger 10 ist eine Radaufhängung 14 zugeordnet, die als Radführungsglieder beispielsweise einen unteren Querlenker 16 und ein Federbein 18 aufweist, das einer­ seits unten einen Radträger 20 für ein lenkbares Vorder­ rad 22 trägt und andererseits oben an der Karosserie ab­ gestützt ist.The side member 10 is assigned a wheel suspension 14 , which has, for example, a lower wishbone 16 and a suspension strut 18 as wheel guide members, which carries a wheel carrier 20 for a steerable front wheel 22 on the one hand and is supported on the top of the body from the other side.

Der einteilig ausgebildete Querlenker 16 ist mit zwei im Abstand voneinander angeordneten Lenkerlagern 24, 26 aus­ gestattet, deren Lagerbohrungen zueinander fluchten. Jedem Lenkerlager 24 bzw. 26 ist ein am Längsträger 10 be­ festigter Lagerbock 28 bzw. 30 zugeordnet, an welchem das Lenkerlager 24 bzw. 26 auf jeweils einer Lager­ achse 32 bzw. 34 gelagert ist. The one-piece wishbone 16 is permitted with two spaced-apart link bearings 24 , 26 , the bearing holes of which are aligned. Each link bearing 24 or 26 is assigned to a side member 10 be fixed bearing block 28 or 30 , on which the link bearing 24 or 26 is mounted on a respective bearing axis 32 or 34 .

Wie die Zeichnung zeigt, umgreift der bezogen auf die Fahrtrichtung F hintere Lagerbock 30 das entsprechende hintere Lenkerlager 26 stirnseitig und legt somit den Querlenker 16 in Richtung seiner durch die Lagerachsen 32, 34 definierten Schwenkachse 36 am Längsträger 10 fest.As the drawing shows, in relation to the direction of travel F, the rear bracket 30 grips the corresponding rear link bearing 26 on the end face and thus fixes the wishbone 16 in the direction of its pivot axis 36 defined by the bearing axles 32 , 34 on the side member 10 .

Der dem vorderen Lenkerlager 24 zugeordnete Lagerbock 28 ist hingegen, zu diesem dahinterliegend, benachbart an­ geordnet. Das Lenkerlager 24 ist somit auf der Lagerachse 34 des vorderen Lagerbockes 28 fliegend gelagert. Diese fliegende Lagerung des vorderen Lenkerlagers 24 bietet im Falle einer auf den Längsträger 10 in Längsrichtung einwirkenden und eine plastische Verformung desselben bewirkenden Aufprallkraft, daß sich der Längsträger 10 auch zwischen den Lagerböcken 28, 30 zur Vernichtung eines Teils der Aufprallenergie entsprechend verformen kann, indem dabei durch die sich während der Verformung des Längsträgers in Richtung der Aufprallkraft voll­ ziehenden Verlagerung des Lagerbockes 28 dieser sich dem Lagerbock 30 nähert, und dabei die Lagerachse 34 gegebenenfalls vollständig aus dem vorderen Lenkerlager 24 herausgezogen wird. Damit ist sichergestellt, daß der ein in sich ausgesteiftes Bauteil bildende Quer­ lenker über dessen an den Lagerböcken 28, 30 gelagerten Lenkerlagern nicht eine mögliche Verformung des die Lagerböcke 28, 30 tragenden Abschnittes 1 eines Fahr­ zeugaufbaues, im vorliegenden Falle des Längsträgers 10, verhindern kann. The front link bearing 24 associated bearing block 28 , however, is arranged behind this, adjacent to it. The link bearing 24 is thus overhung on the bearing axis 34 of the front bearing block 28 . This overhung mounting of the front link bearing 24 offers in the case of an impact force acting on the longitudinal member 10 in the longitudinal direction and causing a plastic deformation thereof, that the longitudinal member 10 can also deform accordingly between the bearing blocks 28 , 30 to destroy part of the impact energy by doing so due to the full displacement of the bearing block 28 during the deformation of the side member in the direction of the impact force, the bearing block 28 approaches the bearing block 30 , and the bearing axis 34 is optionally completely pulled out of the front link bearing 24 . This ensures that the transverse link forming a self-stiffened component over the link bearings mounted on the bearing blocks 28 , 30 does not prevent possible deformation of the bearing blocks 28 , 30 bearing section 1 of a vehicle structure, in the present case the side member 10 .

Selbstverständlich kann die Lagerachse 34 auch am Quer­ lenker 16 befestigt und mit dem Lagerbock 28 in Eingriff gebracht sein.Of course, the bearing axis 34 can also be attached to the transverse link 16 and brought into engagement with the bearing block 28 .

Des weiteren kann bei einer durch zwei Querlenker bewerk­ stelligten Radführung die Lagerung beider Querlenker in der erläuterten Weise vorgesehen sein, wobei der bzw. die Querlenker in einstückiger Ausbildung jede beliebige Form haben können.Furthermore, one can bewerk by two wishbones set the wheel guide the storage of both wishbones in the explained manner can be provided, the or the Wishbones in one piece design of any shape can have.
