Abstract
Description
Die
vorliegende Erfindung betrifft eine Karoserie für ein Kraftfahrzeug mit einem
Hauptrahmen, der sich entlang der Fahrgastzelle und des Motorraums
erstreckende Längsträger umfasst,
und einem Motorrahmen, von dem ein rückwärtiger Bereich an dem Hauptrahmen
befestigt ist. Eine solche Karosserie ist z.B. aus
Die Realisierung des Motorrahmens getrennt vom Hauptrahmen ermöglicht es, Schwingungen des Motors vom Hauptrahmen und damit von der Fahrgastzelle, wo sie zu einer Beeinträchtigung des Fahrkomforts führen würden, abzuschirmen.The Realization of the motor frame separate from the main frame makes it possible Vibrations of the engine from the main frame and thus from the passenger compartment, where they cause an impairment driving comfort would shield.
Als ein Befestigungselement, das den Motorrahmen mit dem Hauptrahmen verbindet, wird üblicherweise eine Schraube oder ein Bolzen eingesetzt, die/der vertikal orientiert ist und einander gegenüber liegende horizontale Auflageflächen des Hauptrahmens und des Motorrahmens in Bezug zueinander fixiert. Ein solcher Bolzen trägt nicht das Gewicht des Fahrzeugs; er erfährt eine kritische Belastung im wesentlichen nur im Falle eines Zusammenstoßes in Form von Scherkräften. Wenn der Bolzen lediglich an einem oberen Ende im Hauptrahmen und an einem unteren Ende in dem Motorrahmen fixiert ist, resultiert aus den bei einem Zusammenstoß auftretenden Kräften ein erhebliches Moment am Bolzen, welches zu einem Verbiegen der den Bolzen tragenden Teile der Rahmen und zu einem Ausreißen des Bolzens führen kann, so dass eine kraftschlüssige Verbindung zwischen Haupt- und Motorrahmen verloren geht. Wenn dies geschieht, können sich während des Zusammenstoßes Karosserieteile gegeneinander bewegen, ohne dabei verformt zu werden und folglich auch ohne Energie zu absorbieren. So wird wertvoller Deformationsraum ungenutzt.When a fastener that attaches the engine frame to the main frame connects, becomes common a screw or a bolt inserted, the / oriented vertically is and opposite each other horizontal bearing surfaces of the main frame and the motor frame fixed with respect to each other. Such a bolt carries not the weight of the vehicle; he experiences a critical burden essentially only in the event of a collision in the form of shear forces. If the bolt only at an upper end in the main frame and on a lower end is fixed in the motor frame results from the forces occurring in a collision considerable moment on the bolt, which leads to a bending of the Bolt carrying parts of the frame and to a tearing of the Bolzens lead can, so a non-positive Connection between main and engine frame is lost. If this happens, can while of the collision Body parts move against each other without being deformed and therefore also without absorbing energy. This is how valuable deformation space becomes unused.
Aufgabe der vorliegenden Erfindung ist, eine Fahrzeugkarosserie anzugeben, die eine ungebremste Beweglichkeit des Motorrahmens in Bezug auf den Hauptrahmen bei einem Zusammenstoß mit größtmöglicher Wahrscheinlichkeit vermeidet.task the present invention is to provide a vehicle body, in terms of unrestricted mobility of the engine frame the main frame in a collision with the greatest possible probability avoids.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass bei einer Kraftfahrzeugkarosserie mit einem Hauptrahmen und einem Motorrahmen, von dem ein rückwärtiger Bereich an dem Hauptrahmen durch ein Befestigungs element befestigt ist, von Haupt- und Motorrahmen der eine wenigstens einen Führungskanal und der anderen einen Arm aufweist, der in einem Eingangsbereich des Führungskanals angeordnet ist, um im Falle der Zerstörung des Befestigungselements in den Führungskanal einzurücken.The The object is achieved in that in a motor vehicle body with a main frame and a Engine frame, of which a rear area attached to the main frame by a fastening element, of main and engine frame one at least one guide channel and the other has an arm which is in an entrance area arranged the guide channel is to be in case of destruction engage the fastener in the guide channel.
Um im Falle eines Frontalzusammenstoßes wirksam zu sein, erstreckt sich der Führungskanal vorzugsweise im wesentlichen in Längsrichtung des Kraftfahrzeugs.Around in the event of a head-on collision the guide channel preferably essentially in the longitudinal direction of the motor vehicle.
Der Führungskanal kann energieabsorbierende Mittel wie etwa einen kompressiblen Werkstoff oder stauchbare Strukturen enthalten.Of the guide channel may be energy absorbing means such as a compressible material or contain compressible structures.
Alternativ oder ergänzend kann eine Energiedissipation beim Eindringen des Arms in den Führungskanal auch dadurch gewährleistet werden, dass der Arm nur unter – vorzugsweise plastischer – Verformung in den Führungskanal einführbar ist.alternative or in addition can dissipate energy as the arm enters the guide channel also guaranteed be that the arm only under - preferably plastic - deformation in the guide channel insertable is.
Um eine feste und sichere Positionierung des Führungskanals zu gewährleisten, erstreckt sich dieser vorzugsweise zwischen einem der Längsträger und einer Mittenverstärkung des Hauptrahmens. So ist z.B. ein Ausweichen des Führungskanals in seitlicher Richtung nicht oder nur schwer möglich, wenn gleichzeitig der Längsträger oder die Mittenverstärkung seitwärts verdrängt werden, was extrem hohe Kräfte erfordert, insbesondere wenn letztere durch eine Bodenplatte verbunden sind.Around to ensure a firm and secure positioning of the guide channel this preferably extends between one of the longitudinal members and a center gain of the main frame. For example, e.g. an evasion of the guide channel in the lateral direction not or only with difficulty, if at the same time Side member or the center gain sideways repressed what are extremely high forces requires, especially if the latter connected by a bottom plate are.
Um eine sichere Führung des Motorrahmens zu gewährleisten, sind vorzugsweise zwei Arme und zwei Führungskanäle vorgesehen.Around a safe guide to ensure the engine frame are preferably provided two arms and two guide channels.
Zweckmäßig ist es auch, wenn sich jeder Arm in einem spitzen Winkel zu dem ihm zugeordneten Führungskanal erstreckt. Um den Arm in den Führungskanal einzuführen, muss er in etwa parallel zum Führungskanal ausgerichtet werden, was eine energieaufwändige plastische Verformung des Motorrahmens erforderlich macht.Is appropriate it is also when each arm is at an acute angle to it associated guide channel extends. To the arm in the guide channel introduce, it has to be roughly parallel to the guide channel be aligned, causing an energy-consuming plastic deformation the engine frame required.
