Abstract
Description
Die Erfindung bezieht sich auf einen Achsträger bzw. einen Hilfsrahmen, auch Fahrschemel genannt, für die Vorderachse von Kraftfahrzeugen.The The invention relates to an axle carrier or a Subframe, also called subframe, for the front axle of motor vehicles.
Durch
die
Derartige Achsträger haben den Nachteil, dass sie aus einer Vielzahl von Einzelteilen zusammengesetzt sind, an denen – vor oder nach dem Zusammenbau dieser Einzelteile – auch noch die Anbindungsstellen für die Karosserieanbindung und für verschiedene Aggregate, wie den Motor, die Lenker und so weiter befestigt werden müssen, in der Regel durch Schweißen.such Axis carriers have the disadvantage that they come from a variety composed of individual parts, on which - before or after assembling these items - even the Connection points for the body connection and for various Aggregates, such as the engine, the handlebars and so on are attached usually, by welding.
Der vorliegenden Erfindung lag die Aufgabe zugrunde, derartige Achsträger rationeller und preiswerter herzustellen, Gewicht einzusparen, die Steifigkeit zu erhöhen und zumindest einzelne der Anbindungsstellen einstückig anzuformen, um den Montageaufwand weiter zu verringern.Of the present invention was the object of such axle to produce more rational and cheaper, to save weight, the Increase stiffness and at least some of the attachment points to form in one piece to further increase the assembly costs reduce.
Der Achsträger gemäß der Erfindung zeichnet sich dadurch aus, dass an den Endbereichen von zwei seitlichen Längsträgern einstückig mit diesen angeformte Anbindungsstellen zur Befestigung des Achsträgers an der Karosserie vorgesehen sind und dass ein flächiges und von den Karosserieanbindungsstellen und den Längsträgern entferntes Versteifungselement vorgesehen ist, das über einstückig diesem angeformten Auslegern wiederum einstückig mit den Karosserieanbindungsstellen verbunden ist.Of the Achsträger draws according to the invention characterized by the fact that at the end of two lateral side rails integral with these molded connection points for Attachment of the axle carrier provided on the body are and that a plane and of the body binding sites and the longitudinal members remote stiffening element is provided, which integrally over this molded Jibs in turn integral with the body attachment points connected is.
Ein solcher Achsträger lässt sich in besonders einfacher und rationeller Weise aus Leichtmetall-Legierungen, wie insbesondere einer Al-Legierung, insbesondere im Druckgussverfahren herstellen.One Such axle can be in a particularly simple and rational way of light metal alloys, in particular an Al alloy, especially in the die-casting process.
Das Versteifungselement kann in vorteilhafter Weise viereckig ausgebildet sein, wobei es sich hinsichtlich der Optimierung der Steifigkeit als besonders vorteilhaft erwiesen hat, wenn dieses Versteifungselement durch wenigstens eine zwischen den Übergangsbereichen des Versteifungselementes in die beiden in Fahrtrichtung vorne liegenden Ausleger verlaufende Verstärkungsrippe in zwei Felder – eines in Fahrtrichtung vorne und eines dahinter liegend – aufgeteilt ist. Dabei hat es sich als besonders vorteilhaft erwiesen, wenn wenigstens eines der Felder eine Wölbung nach unten, also in Richtung zur Fahrbahn, besitzt, wobei es sich wiederum als vorteilhaft erwiesen hat, wenn das gewölbte Feld das vordere ist. Weiterhin hat es sich als vorteilhaft erwiesen, wenn die Verstärkungsrippe ebenfalls nach oben gerichtet ist.The Stiffening element can be formed square in an advantageous manner which is in terms of optimization of rigidity has proved to be particularly advantageous if this stiffening element by at least one between the transitional areas of the Stiffening element in the two in the direction of travel forward Boom extending reinforcing rib in two fields - one in Direction of travel in front and one behind - split is. It has proved to be particularly advantageous if at least one of the fields a vault down, so in the direction of the roadway, which in turn proved to be advantageous has, if the arched field is the front. Farther It has proven to be advantageous if the reinforcing rib also directed upward.
Es hat sich weiterhin als die Steifigkeit erhöhend und das einzusetzende Gewicht verringernd erwiesen, das Versteifungselement von Versteifungsrippen zu umgeben, wobei weiterhin vorteilhaft ist, wenn zumindest die die vorderen Übergangsbereiche verbindende Versteifungsrippe nach oben gerichtet ist.It has continued to increase as the stiffness and the The weight to be used has been found to reduce the stiffening element surrounded by stiffening ribs, wherein it is also advantageous if at least the connecting the front transition areas Stiffening rib is directed upwards.
Zweckmäßig hat sich weiterhin erwiesen, die – in Fahrtrichtung gesehen vorderen Karosserieanbindungsstellen – durch je einen nach oben und von den Längsträgern nach vorne gerichteten, einstückig mit diesen ausgebildeten Aufsatz auszubilden, wobei jede Karosserieanbindungsstelle mindestens zwei über eine Brücke voneinander beabstandete Befestigungsstellen besitzt. Diese Aufsätze sind zweckmäßigerweise über einen Querträger miteinander verbunden, der einstückig ausgebildet ist mit den Aufsätzen.expedient has continued to prove that - seen in the direction of travel front body attachment points - by one after each above and from the longitudinal members forward, integrally form with this trained essay, wherein each body attachment site at least two a bridge spaced attachment points has. These essays are expediently over a cross-beam interconnected, the one-piece is designed with the essays.
Der erfindungsgemäße Achsträger besitzt weiterhin neben den Anbindungsstellen zur Befestigung an der Karosserie auch noch angeformte Anbindungsstellen zumindest für den Motor, die Querlenker und das Lenkgetriebe.Of the Axis carrier according to the invention still has in addition to the attachment points for attachment to the bodywork also still integrally formed connection points at least for the engine, the wishbones and the steering gear.
