Description
Die Erfindung bezieht sich auf ein Frontendmodul gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to a front end module according to the preamble of patent claim 1.
Bei solchen Frontendmodulen besteht der Wunsch, den Montageträger mit möglichst hohem Integrationsumfang auszuführen, um die Montage des betreffenden Fahrzeugs zu vereinfachen, hier vor allem Montage- und Handlingskosten zu sparen. Bei einem erheblichen Ausbauumfang des Montageträgers besteht allerdings die Gefahr, daß im Crashfalle beim Ausfall nur einer der Funktionen, die der Montageträger zu erfüllen hat, der gesamte Montageträger ausgetauscht werden müßte. Dies betrifft vor allem solche Montageträger, an denen Einrichtungen für den Fußgängerschutz beim Unterschenkelaufprall vorgesehen sind.at Such front end modules is the desire with the mounting bracket preferably to carry out a high degree of integration, to simplify the installation of the vehicle in question, here especially to save assembly and handling costs. At a considerable Expansion scope of the mounting bracket However, there is a risk that in case of failure in the event of a crash only one of the functions that has to meet the mounting bracket, replaced the entire mounting bracket would have to be. This especially concerns those mounting vehicles, where facilities for the pedestrian protection are provided at the lower leg impact.
Die Reparaturbedürftigkeit eines Fahrzeugfrontendmoduls im Beschädigungsfall ist für die Einstufung in die Fahrzeugversicherung von Bedeutung, und deshalb werden zur Reparaturkostenabschätzung Crashtests durchgeführt. Dabei dürfen im Hinblick auf den zu erzielenden Fußgängerschutz vorgegebene biomechanische Werte nicht überschritten werden, was bedeutet, daß der untere Bereich des Frontendmoduls, der dem Unterschenkelaufprallbereich entspricht, aufgrund der hier vorzusehenden Deformationsmöglichkeiten anfällig für Beschädigungen ist. Im praktischen Fahrzeugbetrieb können solche Beschädigungen durch Kollisionen des Fahrzeugs mit bodennahen Hindernissen leicht auftreten. Darauf muß besonders dann Rücksicht genommen werden, wenn die Schutzvorrichtung für den Fußgängeraufprall am Montageträger des Fahrzeugfrontendmoduls angeordnet ist, um eine günstige Reparaturmöglichkeit mit entsprechender Versicherungseinstufung zu erreichen.The requiring repair a vehicle front end module in case of damage is for classification in the vehicle insurance of importance, and therefore become the Repair cost estimate Crash tests performed. In doing so may Given the pedestrian protection to be achieved given biomechanical Values should not be exceeded which means that the lower portion of the front end module, the lower leg impact area corresponds, due to the deformation possibilities to be provided here susceptible for damage is. In practical vehicle operation such damage by collision of the vehicle with ground-level obstacles easily occur. It must be special then consideration be taken when the protective device for the pedestrian impact on the mounting bracket of the Vehicle front end module is arranged to provide a cheap repair to achieve with appropriate insurance classification.

Der Erfindung liegt deshalb die Aufgabe zugrunde, ein Fahrzeugfrontendmodul der eingangs genannten Art zu schaffen, bei dem der Montageträger sowohl die Erfordernisse des Fußgängeraufprallschutzes im Unterschenkelbereich erfüllt als auch an ihm im Falle eines Aufpralles auf ein Hindernis im niedrigen Geschwindigkeitsbereich die hierdurch hervorgerufene Beschädigung leicht repariert werden kann.Of the The invention is therefore based on the object, a Fahrzeugfrontendmodul of the type mentioned above, in which the mounting bracket both the requirements of pedestrian impact protection met in the lower leg area as well as at him in case of an impact on an obstacle in the low Speed range the damage caused thereby easily can be repaired.
Diese Aufgabe wird bei einem Fahrzeugfrontendmodul der vorgenannten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.These Task is in a vehicle front end module of the aforementioned type solved by the characterizing features of claim 1.
Für die Erfindung ist wesentlich, daß beim Auffahren des Fahrzeugs mit niedriger Geschwindigkeit auf ein bodennahes Hindernis, wie es bei Rangierfällen oft vorkommt, lediglich das Deformationselement am unteren Querträger des Montageträgers beschädigt wird und durch Austausch des Deformationselementes der Schaden leicht behoben werden kann. Denn in Relation zu dem Deformationselement sind die den Querträger des Montageträgers haltenden Streben so biegesteif ausgeführt, daß in Kollisionsfällen der genannten Art der Montageträger selbst nicht Schaden nimmt.For the invention is essential that when driving low-speed vehicle to a ground-level obstacle, like in shunting cases often occurs, only the deformation element on the lower cross member of the Mounting support is damaged and by replacing the deformation element the damage easily can be corrected. Because in relation to the deformation element the cross member of the mounting carrier holding struts so rigidly executed that in collision cases the mentioned type of mounting bracket itself does not hurt.
