Abstract
Description
Die Erfindung betrifft ein Karosseriebauteil für einen Kraftwagen, insbesondere einen Personenkraftwagen, der im Oberbegriff des Patentanspruchs 1 angegebenen Art.The The invention relates to a body component for a motor vehicle, in particular a passenger car, which in the preamble of claim 1 specified type.
Ein
solches Karosseriebauteil ist beispielsweise bereits aus der
Aufgabe der vorliegenden Erfindung ist es, ein Karosseriebauteil der eingangs genannten Art zu schaffen, welches hinsichtlich seiner akustischen Dämpfungseigenschaften optimiert ist.task The present invention is a body component of the above mentioned type, which in terms of its acoustic damping properties is optimized.
Diese Aufgabe wird erfindungsgemäß durch ein Karosseriebauteil mit den Merkmalen des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den übrigen Patentansprüchen angegeben.These The object is achieved by a Body component solved with the features of claim 1. advantageous Embodiments with appropriate and Non-trivial developments of the invention are specified in the remaining claims.
Um ein hinsichtlich seiner akustischen Dämpfungseigenschaften optimiertes Karosseriebauteil zu schaffen, mit gleichzeitig möglichst hoher Steifigkeit, ist es erfindungsgemäß vorgesehen, dass die jeweilige Hohlkammer zumindest über eine Teillänge des zugeordneten wenigstens einen Hohlprofils mit dem Dämpfungs- und/oder Versteifungsschaum zumindest annähernd vollständig ausgefüllt ist. Mit anderen Worten ist es erfindungsgemäß vorgesehen, die jeweilige Hohlkammer des entsprechenden Hohlprofils zumindest abschnittsweise vollständig bzw. über deren gesamten Querschnitt mit dem Dämpfungs- und/oder Versteifungsschaum zu verfüllen, um hierdurch insbesondere die dynamischen Eigenschaften der Karosserie bzw. der Rohbaustruktur deutlich zu verbessern. Insbesondere ist es hierdurch möglich, die Torsionsfrequenz, die Biegefrequenz und die lokalen Eigenschaften an Koppel- bzw. Anbindungsstellen des Karosseriebauteils so auszulegen, dass sich besonders günstige dynamische Eigenschaften des Kraftwagens ergeben.Around an optimized in terms of its acoustic damping properties To create body component, with as possible high rigidity, it is provided according to the invention that the respective Hollow chamber at least about a partial length the associated at least one hollow profile with the damping and / or stiffening foam is at least approximately completely filled. In other words, it is provided according to the invention Hollow chamber of the corresponding hollow profile at least in sections Completely or over their entire cross section with the damping and / or stiffening foam to fill in, in order thereby in particular the dynamic characteristics of the body or the shell structure significantly improve. In particular it is thereby possible, the torsional frequency, the bending frequency and the local characteristics at coupling or attachment points of the body component so interpreted, that is especially cheap give dynamic characteristics of the motor vehicle.
Ein weiterer Vorteil des erfindungsgemäßen Karosseriebauteils ist es, dass durch die zumindest annähernd vollständige Ausfüllung der entsprechenden Hohlkammer nicht nur eine verbesserte Akustik des Kraftwagens erreicht werden kann, sondern auch eine deutliche Versteifung. Durch den innerhalb der jeweiligen Hohlkammer angeordneten Dämpfungs- und/oder Versteifungsschaum wird nämlich erreicht, dass sich innerhalb der Hohlkammer ausbreitende Schwingungen entsprechend gedämpft werden. Insgesamt ist somit erkennbar, dass mittels des Einsatzes des Dämpfungs- und/oder Versteifungsschaums sowohl eine deutlich verbesserte Versteifung wie auch eine verbesserte Fahrzeugakustik hergestellt werden kann. Durch diese Maßnahmen resultieren Fahrzeugeigenschaften wie beispielsweise ein großer Abstand zwischen Achsresonanzen, Aufbauresonanzen und Resonanzen von Subsystemen wie beispielsweise der Lenkung. Somit ergeben sich deutlich größere Spielräume bei der Fahrzeugabstimmung.One Another advantage of the body part according to the invention is it that by at least approximately full filling the corresponding hollow chamber not only improved acoustics of the Motor vehicle can be achieved, but also a significant stiffening. By means of the damping mechanism arranged inside the respective hollow chamber and / or stiffening foam is namely achieved that within the hollow chamber propagating vibrations are attenuated accordingly. Overall, it can thus be seen that by means of the use of the damping and / or stiffening foam both a significantly improved stiffening as well as improved vehicle acoustics can be made. These measures result Vehicle characteristics such as a large distance between axle resonances, mounting resonances and resonances of subsystems such as steering. Consequently result in significantly greater margins the vehicle vote.
Ein weiterer Vorteil der erfindungsgemäßen vollständigen Ausfüllung der Hohlkammer des zugehörigen Hohlprofils über wenigstens eine Teillänge ist es, dass sich hierdurch ein verbessertes Crashverhalten des Karosseriebauteils realisieren lässt. Dieses verbesserte Crashverhalten kann sich beispielsweise in einer verbesserten Beul- oder Knicksteifigkeit des Karosseriebauteils äußern, und zwar insbesondere in demjenigen Bereich, in welchem der Dämpfungs- und/oder Versteifungsschaum innerhalb des Hohlprofils angeordnet ist.One Another advantage of the invention complete filling of the hollow chamber of the associated hollow profile over at least a partial length it is that this results in an improved crash behavior of the Car body components can be realized. This improved crash behavior can, for example, in a express improved buckling or buckling stiffness of the body component, and although in particular in the area in which the damping and / or stiffening foam is disposed within the hollow profile.
