Description
Die Erfindung betrifft eine Fahrzeugkarosserie mit einem ersten Längsträger, an welchem ein Hilfsrahmen festgelegt ist. Ein zweiter Längsträger ist bezogen auf die Fahrzeughochrichtung unterhalb des ersten Längsträgers angeordnet.The invention relates to a vehicle body with a first side member on which a subframe is fixed. A second longitudinal member is arranged with respect to the vehicle vertical direction below the first longitudinal member.
Die
Bei einer derartigen Karosserie erweist es sich bisweilen als schwierig, den unteren Längsträger so anzubringen, dass er seiner Funktion, insbesondere dem verbesserten Abstützen des Frontmodulträgers, gerecht wird.In such a body, it sometimes turns out to be difficult to attach the lower side member so as to do justice to its function, in particular the improved support of the front module carrier.
Die
Aufgabe der vorliegenden Erfindung ist es daher, eine Fahrzeugkarosserie der eingangs genannten Art zu schaffen, bei welcher der untere und obere Längsträger ihre Funktionen besser erfüllen können.Object of the present invention is therefore to provide a vehicle body of the type mentioned, in which the lower and upper side members can perform their functions better.
Diese Aufgabe wird durch eine Fahrzeugkarosserie mit den Merkmalen des Patentanspruchs 1 gelöst. Eine vorteilhafte Ausgestaltungen der Erfindung ist in dem abhängigen Patentanspruch 2 angegeben.This object is achieved by a vehicle body having the features of patent claim 1. An advantageous embodiments of the invention is specified in the dependent claim 2.
Die Fahrzeugkarosserie umfasst ein Koppelteil mit mindestens einem Langloch und einem Anschlag an dem der untere Längsträgers am Hilfsrahmen positioniert und dann verbunden wird. Dadurch ist ein Aufbau möglich, bei dem obere und untere Längsträger trotz Toleranzen sowohl mit dem Frontendmodul als auch mit dem Hilfsrahmen fest und spielfrei verbunden werden können. In einem ersten Zustand ist das Koppelteil relativ zu dem zweiten Längsträger in wenigstens eine Richtung bewegbar und in einem zweiten Zustand ist das Koppelteil an dem Hilfsrahmen fixiert. Das Koppelteil kann also in dem ersten Zustand so bewegt werden, dass ein anschließendes prozesssicheres Verbauen des zweiten Längsträgers an der für diesen in dem Kraftfahrzeug vorgesehenen Position ermöglicht ist.The vehicle body comprises a coupling part with at least one oblong hole and a stop on which the lower longitudinal member is positioned on the subframe and then connected. As a result, a structure is possible in which the upper and lower side members can be connected firmly and without play despite tolerances both with the front end module and with the subframe. In a first state, the coupling part is movable relative to the second side member in at least one direction and in a second state, the coupling part is fixed to the subframe. The coupling part can thus be moved in the first state so that a subsequent process-reliable obstruction of the second longitudinal member is made possible at the position provided for this in the motor vehicle.
Hierbei liegt der Erfindung die Erkenntnis zugrunde, dass es beim Anbringen an den Hilfsrahmenan dem ersten Längsträger in unterschiedlichen Fahrzeugen zu voneinander abweichenden Positionen des Hilfsrahmenbezogen auf den ersten Längsträger kommen kann. Solche Abweichungen können auch auftreten, wenn baugleiche Tragstrukturen in Fahrzeugen desselben Typs verbaut werden. Wird dann der untere Längsträger an den Hilfsrahmen angebunden, kann es zu einer ungünstigen, beispielsweise schiefen, Ausrichtung des unteren Längsträgers kommen. Das in wenigstens eine Richtung bewegbare Koppelteil ermöglicht nun ein Ausgleichen der Abweichungen und stellt so Toleranzen bereit. Sind die Abweichungen kompensiert, kann das Koppelteil an dem Hilfsrahmen fixiert werden. Anschließend kann dann das lagerichtige Koppeln des zweiten Längsträgers an den Hilfsrahmenmittels des Koppelteils erfolgen. Die absolute Position des zweiten, unteren Längsträgers kann somit so eingestellt werden, wie es für das Erfüllen seiner Funktionen wünschenswert ist, und zwar unabhängig von der – auch bei baugleichen Fahrzeugen – gegebenenfalls unterschiedlichen absoluten Position der wenigstens einen Tragstruktur. Auf diese Weise ist mittels des unteren Längsträgers bei Anordnung desselben im Vorderwagen des Kraftfahrzeugs eine verbesserte Abstützung eines Frontmodulträgers, eine verbesserte Versteifung des Vorderwagens und eine Verbesserung des Deformationsverhaltens in der Ebene des unteren Längsträgers erreichbar. Da ein schiefes Verbauen des unteren Längsträgers vermeidbar ist, kann der untere Längsträger die ihm zugedachten Funktionen besonders gut erfüllen.In this case, the invention is based on the finding that, when attached to the subframe on the first side member in different vehicles, it may come to differing positions of the subframe relative to the first side member. Such deviations can also occur when structurally identical support structures are installed in vehicles of the same type. Then, when the lower side member is connected to the subframe, it may lead to an unfavorable, for example oblique, alignment of the lower side member. The coupling part which can be moved in at least one direction now makes it possible to compensate the deviations and thus provides tolerances. If the deviations are compensated, the coupling part can be fixed to the subframe. Subsequently, the positionally correct coupling of the second longitudinal member to the subframe can take place by means of the coupling part. The absolute position of the second, lower longitudinal member can thus be set as it is desirable for fulfilling its functions, regardless of the - even with identical vehicles - possibly different absolute position of the at least one support structure. In this way, an improved support of a front module carrier, improved stiffening of the front end of the vehicle and an improvement in the deformation behavior in the plane of the lower longitudinal member can be achieved by means of the lower longitudinal member in the front of the motor vehicle. Since an oblique installation of the lower longitudinal member can be avoided, the lower side member can fulfill its intended functions particularly well.
Bevorzugt umfasst das Koppelteil einen plattenförmigen Grundkörper, auf dem ein L-förmiger Flansch mit Anschlägen angebracht ist. Dadurch ist eine flächige und somit besonders stabile Anlage des Koppelteils an den Hilfsrahmen erreichbar.Preferably, the coupling part comprises a plate-shaped base body, on which an L-shaped flange is attached with stops. As a result, a flat and thus particularly stable system of the coupling part to the subframe is reached.
Der Hilfsrahmen und/oder das Koppelteil können wenigstens eine Ausnehmung aufweisen, welche im ersten Zustand ein Verschieben des Koppelteils relativ zu einem Fixierelement ermöglicht, mittels welchem das Koppelteil an den Hilfsrahmen fixierbar ist. Der Größenunterschied zwischen dem Durchmesser des Fixierelements, etwa einer Schraube, und einer Weite der Ausnehmung bestimmt dann den möglichen Verschiebeweg des Koppelteils, welcher es ermöglicht, das Koppelteil bezogen auf den zweiten Längsträger lagerichtig auszurichten.The subframe and / or the coupling part can have at least one recess which, in the first state, enables a displacement of the coupling part relative to a fixing element, by means of which the coupling part can be fixed to the subframe. The difference in size between the diameter of the fixing element, such as a screw, and a width of the recess then determines the possible displacement of the coupling part, which makes it possible to align the coupling part relative to the second side member in the correct position.
