Abstract
Description
Die Erfindung bezieht sich auf einen Hilfsrahmen, insbesondere einen Hinterachshilfsrahmen für Kraftfahrzeuge mit Mehrlenker-Hinterachsen.The The invention relates to a subframe, in particular a Rear-axle auxiliary frame for motor vehicles with multi-link rear axles.
Solche Mehrlenker-Hinterachsen bieten für sich optimale Möglichkeiten zur gezielten Beeinflussung der Radführung und des Fahrverhaltens in den verschiedensten Fahrsituationen. Die Lenker und auch andere Elemente eines Fahrzeuges werden dabei in der Regel auf einem Hilfsrahmen, auch als Fahrschemel oder Achsträger bezeichnet, zu einer Einheit vormontiert und diese an Karosseriebereichen bzw. dem Chassis befestigt.Such Multi-link rear axles offer for themselves optimal possibilities for specific influencing of the wheel guidance and the driving behavior in a variety of driving situations. The handlebars and others Elements of a vehicle are usually on a subframe, also as subframe or axle carrier designated, preassembled into a unit and these body parts or attached to the chassis.
Die bisher bekannten so ausgebildeten Hinterachsen haben jedoch häufig den Nachteil eines sehr hohen Fertigungsaufwandes und sind dementsprechend kostenintensiv.The However, previously known so-trained rear axles often have the Disadvantage of a very high production costs and are accordingly expensive.
Der vorliegenden Erfindung lag die Aufgabe zugrunde, solche Hinterachsen schneller, einfacher und damit kostengünstiger herzustellen und die Einsatzmöglichkeiten zu erweitern, was wegen der damit verbundenen höheren Stückzahlen wiederum zu preisgünstigeren Erzeugnissen führt.Of the present invention was the object of such rear axles faster, easier and thus cheaper to manufacture and the applications to expand, which in turn because of the associated higher volumes to cheaper Products.
Weiterhin sollen durch Einsatz von fortschrittlichen und kostengünstigen Gießtechnologien sowie optimaler Materialien die Kosten weiter gesenkt, die Genauigkeit erhöht und die Qualität verbessert werden.Farther should be through the use of advanced and cost-effective Casting technologies as well optimal materials further reduced costs, accuracy elevated and the quality be improved.
Gemäß der Erfindung wird dies dadurch erzielt, dass ein Hilfsrahmen, insbesondere ein Hinterachs-Hilfsrahmen derart ausgestaltet wird, dass er aus zwei Hilfsrahmen-Seitenteilen besteht, die zumindest annähernd V-förmig ausgebildet sind, in einer solchen Anordnung, dass deren Scheitelpunkte aufeinander zu gerichtet sind und über ein quer zur Fahrzeuglängsachse liegendes Hilfsrahmen-Mittelteil miteinander verbunden sind, die Hilfsrahmen-Seitenteile und das Hilfsrahmen-Mittelteil als Hohlprofile ausgebildet sind und die Hilfsrahmen-Seitenteile zumindest drei der nachfolgend angeführten Aufnahmen bzw. Ausnehmungen für
- – die oberen Querlenker
- – die unteren Querlenker
- – den Stabilisator
- – die Längslenker
- – die Befestigung des Hilfsrahmens an der Karosserie
- - the upper wishbones
- - the lower wishbones
- - the stabilizer
- - the trailing arm
- - The attachment of the subframe to the body
Dabei kann es besonders vorteilhaft sein, wenn die V-förmigen Hilfsrahmen-Seitenteile einen U-förmigen Querschnitt aufweisen mit zwischen den Schenkeln verlaufenden Verstärkungsrippen.there It may be particularly advantageous if the V-shaped subframe side parts have a U-shaped cross-section having extending between the legs reinforcing ribs.
Die V-förmigen Seitenteile können in ihrem Scheitelbereich den Fuß eines Y angeformt haben mit einem dem Hilfsrahmen-Mittelteil entsprechenden Querschnitt, wobei das Hilfsrahmen-Mittelteil in den Scheitelbereichen bzw. dem Fußbereich des Y aufgenommen sein kann. Als Profil für das Hilfsrahmen-Mittelteil kann sich in besonders vorteilhafter Weise ein viereckiges Hohlprofil eignen, das ein Strangpressprofil sein kann.The V-shaped Side parts can in her vertex the foot of a Y have formed with a subframe middle part corresponding Cross section, wherein the subframe middle part in the apex areas or the footer of the Y can be recorded. As a profile for the subframe middle part may be in a particularly advantageous manner, a quadrangular hollow profile are suitable, which can be an extruded profile.
Bei Einsatz unterschiedlich langer Hilfsrahmen-Mittelteile können Fahrzeuge mit unterschiedlicher Spurbreite mit einheitlichen Hilfsrahmen-Seitenteilen ausgerüstet werden, was wegen der zum Einsatz kommenden höheren Stückzahlen eine preiswerte Herstellung erheblich begünstigt.at Use of different length subframe middle parts can vehicles with different track width with uniform subframe side parts equipped which, due to the higher quantities used, is an inexpensive production considerably favored.
Vorteilhaft ist es weiterhin, wenn die Hilfsrahmen-Seitenteile und/oder das Hilfsrahmen-Mittelteil aus Leichtmetall bestehen, wobei sich in besonders günstiger Weise Al-Legierungen eignen. Dabei können die Hilfsrahmen-Seitenteile Druckgussteile sein und das Hilfsrahmen-Mittelteil, wie bereits erwähnt, ein Strangpressprofil. Solche Teile lassen sich auch in relativ einfacher Weise miteinander durch Schweißen verbinden.Advantageous it is still when the subframe side parts and / or the Subframe middle part made of light metal, with in especially cheaper Al alloys are suitable. The subframe side parts can die-cast parts be and the subframe middle part, as already mentioned, a Extruded profile. Such parts can also be relatively easier Wise together by welding connect.
Die Ausnehmungen zur Befestigung des Hilfsrahmens an der Karosserie bzw. zur Durchführung von Befestigungselementen sind dabei zweckmäßigerweise jeweils am Ende der Schenkel der Hilfsrahmen-Seitenteile vorgesehen.The Recesses for attaching the subframe to the body or for implementation of fasteners are expediently in each case at the end provided the leg of the subframe side panels.
Ein weiterer erfinderischer Gedanke bezieht sich auf eine besondere Ausgestaltung eines Längslenkers, der sowohl im Zusammenhang mit einem Hilfsrahmen der beschriebenen Art verwendet werden kann, als auch bei andersartig gestalteten Hinterachsen. Dieser zeichnet sich dadurch aus, dass derselbe in seinem Bereich zwischen einem Anlenkpunkt am Hilfsrahmen und seinem am anderen Ende einstückig angeformten Radträgerbereich ein Hohlprofil ist. Dabei kann das Hohlprofil ein geschlossenes Profil, zum Beispiel ein Rundprofil sein, das vorzugsweise aus Leichtmetall besteht, zum Beispiel aus einer Al-Legierung.One Another inventive idea refers to a particular one Embodiment of a trailing arm, which is described both in connection with a subframe of the Art can be used as well as otherwise styled Rear axles. This is characterized by the fact that the same in his area between a pivot point on the subframe and his in one piece at the other end molded wheel carrier area a hollow profile is. In this case, the hollow profile is a closed Profile, for example, be a round profile, preferably made of light metal consists, for example, of an Al alloy.
Besonders vorteilhaft in Bezug auf eine zu erzielende hohe Steifigkeit ist es, wenn der Längslenker in seinem Bereich zwischen Befestigungsstelle am Hilfsrahmen und seinem Radträgerbereich zusätzlich einen Hohlkörper enthält, wobei es hinsichtlich einer zu erzielenden Leichtbauweise vorteilhaft sein kann, wenn der Längslenker ein Al-Kokillengussteil ist, in dem der weitere Hohlkörper eingegossen ist.It is particularly advantageous with respect to a high rigidity to be achieved if the trailing arm additionally contains a hollow body in its region between attachment point on the subframe and its wheel carrier area, wherein it can be advantageous in terms of a lightweight design to be achieved if the trailing arm is an Al-die casting , in which the other hollow body gegos is sen.
