Abstract
Description
Bei der Erfindung wird ausgegangen von einer Kraftfahrzeugkarosserie gemäß Oberbegriff des Anspruchs 1.The invention is based on of a motor vehicle body according to the preamble of the claim 1.
Eine gattungsbildende Kraftfahrzeugkarosserie
ist aus der
Aufgabe der Erfindung ist es, eine Kraftfahrzeugkarosserie anzugeben, die hinsichtlich ihres Torsions- bzw. Biegeverhaltens und der Körperschalldämpfung optimiert ist.The object of the invention is a To specify motor vehicle body, which with regard to its torsional or bending behavior and structure-borne noise reduction optimized is.
Gelöst wird diese Aufgabe mit einer Kraftfahrzeugkarosserie mit den in Anspruch 1 genannten Merkmalen. Weitere Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This task is solved with a Motor vehicle body with the features mentioned in claim 1. Further refinements of the invention are specified in the subclaims.
Die mit der Erfindung hauptsächlich erzielten Vorteile sind darin zu sehen, dass mit dem den viskoelastischen Kunststoff aufweisenden Dämpfungselement sowohl Karosseriehauptmoden (Torsions- und Biegeschwingformen) als auch lokale Karosserieschwingformen zu bedämpfen sind, so dass außerdem mit dem Dämpfungselement dem Rahmengestell Körperschallenergie entzogen werden kann. In das Dämpfungselement eingeleitete Schwingungen werden in dem viskoelastischen Kunststoff durch innere Reibung in Wärme umgewandelt. Außerdem zeichnet sich das vorgeschlagene Dämpfungselement durch einen einfachen Aufbau aus und bietet Dämpfungseigenschaften über einen großen Frequenzbereich (ca. 20Hz bis 30kHz) der Schwingformen.The main advantages achieved with the invention can be seen in that with the viscoelastic plastic having damping element both main body modes (torsion and bending modes) as also local body vibrations are to be dampened, so that also with the damping element the structure-borne sound energy frame can be withdrawn. In the damping element Vibrations are introduced into the viscoelastic plastic through internal friction in heat converted. Also draws the proposed damping element through a simple structure and offers damping properties over a huge Frequency range (approx. 20 Hz to 30 kHz) of the waveforms.
Bei einem Ausführungsbeispiel gemäß Anspruch 2 wird eines der Dämpferteile von einem Rohr gebildet, dessen innere Querschnitt derart bemessen ist, dass das andere Dämpferteil mit Abstand zur inneren Rohrwandung liegt, wodurch der Spalt, in dem der viskoelastische Kunststoff angeordnet ist, als umlaufender Spaltraum vorliegt. Derartige, vorzugsweise dünnwandige und steife, Rohre könnten einen eckigen oder kreisförmigen Querschnitt besitzen.In an embodiment according to claim 2 becomes one of the damper parts formed by a tube, the inner cross section of which is dimensioned in such a way that the other damper part is at a distance from the inner tube wall, whereby the gap, in which the viscoelastic plastic is arranged as a circumferential There is a gap. Such, preferably thin-walled and rigid, pipes could an angular or circular Have cross-section.
Nach einem anderen Ausführungsbeispiel nach Anspruch 3 weisen die Dämpferteile jeweils eine Kammstruktur auf, die unter Bildung mehrere Spalte mit ihren Zähnen ineinander greifen, und in dem so gebildeten Spalträumen ist der viskoelastische Kunststoff angeordnet. Bei dieser Ausführungsform wird die Oberfläche an der Kontaktfläche mit dem viskoelastischen Kunststoff vergrößert, wodurch höhere Energiemengen in Wärme umsetzbar sind.According to another embodiment Claim 3 have the damper parts one comb structure each, forming several columns with her teeth interlock, and is in the gap spaces thus formed the viscoelastic plastic arranged. In this embodiment becomes the surface at the contact surface enlarged with the viscoelastic plastic, which means higher amounts of energy in warmth are feasible.
Als Werkstoff für die Dämpferteile wird entsprechend Anspruch 7 ein Körperschall leitendes Material, bspw. Stahl, Aluminium und/oder Kunststoff aufweisend, vorgeschlagen, wodurch der Körperschall in den viskoelastischen Kunststoff des Dämpfungselements geleitet wird.As a material for the damper parts is accordingly Claim 7 a structure-borne noise comprising conductive material, for example steel, aluminum and / or plastic, proposed, causing the structure-borne noise is passed into the viscoelastic plastic of the damping element.
Die Erfindung wird nachfolgend anhand von Ausführungsbeispielen mit Bezug auf die Zeichnung näher erläutert. Es zeigen:The invention is described below of embodiments with reference to the drawing explained. Show it:
