Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, für eine gattungsgemäße Kopplungsvorrichtung, eine verbesserte oder zumindest eine andere Ausführungsform anzugeben, die insbesondere ein geringes Gewicht aufweist und einfach zu montieren ist.Of the The present invention is therefore based on the object for a generic coupling device, a improved or at least another embodiment Specify, in particular, has a low weight and easy to assemble is.
Dieses Problem wird erfindungsgemäß durch den Gegenstand des unabhängigen Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen sind Gegenstand der abhängigen Ansprüche.This Problem is inventively by the subject of the independent claim 1 solved. advantageous Embodiments are the subject of the dependent Claims.
Die vorliegende Erfindung beruht auf dem allgemeinen Gedanken, eine zwischen einer Innenwelle und einer koaxial dazu angeordneten Außenwelle einer Fahrzeuglenkspindel angeordnete elastische Schicht als Dämpfungselement auszubilden und drehfest mit der Innenwelle zu verbinden, insbesondere auf diese aufzuspritzen, wobei das Dämpfungselement gleichzeitig in der Art eines Außenmehrkants ausgebildet wird, der in einen komplementär dazu ausgebildeten Innenmehrkant der Außenwelle eingreift und dadurch sowohl einerseits eine insbesondere vibrationsdämpfende Wirkung entfalten kann, andererseits aber zugleich eine zuverlässige Drehmomentenübertragung gewährleistet. Vorzugsweise ist dabei das Dämpfungselement aus Kunststoff ausgebildet und wird auf die Innenwelle aufgespritzt, wobei während des Aufspritzvorgangs zugleich eine drehfeste Verbindung mit der Innenwelle hergestellt wird. Zur Herstellung des erfindungsgemäß ausgebildeten Dämpfungselements muss lediglich eine entsprechend ausgebildete Spritzform geschaffen werden, mit Hilfe welcher eine Vielzahl derartiger Dämpfungselemente kostengünstig herstellbar ist. Gleichzeitig vereinfacht sich mit dem erfindungsgemäß angeordneten Dämpfungselement die Montage der Fahrzeuglenkspindel erheblich, wodurch die Fertigungskosten im Kraftfahrzeugbereich gesenkt werden können.The The present invention is based on the general idea, a between an inner shaft and a coaxially arranged outer shaft a vehicle steering shaft arranged elastic layer as a damping element form and rotatably connected to the inner shaft, in particular aufzuspritzen on this, wherein the damping element at the same time is formed in the manner of an outer polygon, which in a complementary trained inner polygon of Outer shaft engages and thereby on the one hand a especially unfolds vibration-damping effect, on the other hand, but at the same time a reliable torque transmission guaranteed. Preferably, the damping element is made Plastic formed and is sprayed onto the inner shaft, during the injection process at the same time a non-rotatable Connection with the inner shaft is made. For the production of the inventively designed damping element must only a suitably trained injection mold can be created, with the help of which a plurality of such damping elements is inexpensive to produce. Simultaneously simplified with the damping element arranged according to the invention the mounting of the vehicle steering spindle significantly, thereby reducing the manufacturing costs can be lowered in the automotive field.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, ist das Dämpfungselement aus Kunststoff, insbesondere aus einem Elastomer, ausgebildet. Elastomere sind formfeste aber elastisch verformbare Kunststoffe, deren Glasübergangspunkt sich unterhalb der Raumtemperatur befindet. Aus diesem Grund können sich derartige Kunststoffe bei Zug- und Druckbelastung elastisch verformen, finden aber danach wieder in ihre ursprüngliche, unverformte Gestalt zurück. Das besondere an Elastomeren ist, dass ihre Elastizität nicht auf Anziehungskräften zwischen sich ändernden Atomabständen beruht, sondern ein statisch-dynamisches Gleichgewicht zwischen Ordnung und Entropie darstellt. Das Elastomer speichert daher keinerlei Spannenergie in sich selbst, sondern strahlt die beim Dehnen zugeführte Energie als Wärme aus und erhöht stattdessen seine innere Ordnung. Für ein erneutes Zusammenziehen benötigt daher das Elastomer die Zufuhr von Energie, welche es bspw. durch Brownsche Molekularbewegungen der Umgebungswärme entnimmt. Generell sind derartige Elastomere hinsichtlich ihrer Eigenschaften relativ flexibel einstellbar, so dass mit derartigen Elastomeren insbesondere ein bei Kraftfahrzeugen auftretender großer Temperatureinsatzbereich mühelos abgedeckt werden kann. Zudem sind Elastomere vergleichsweise kostengünstige Werkstoffe die ihre Elastizität und damit auch ihr Dämpfungsverhalten über einen langen Zeitraum erhalten können.at an advantageous embodiment of the invention Solution, is the damping element made of plastic, in particular made of an elastomer. Elastomers are dimensionally stable but elastically deformable plastics whose glass transition point is below room temperature. That's why such plastics deform elastically under tensile and compressive loading, but then return to their original, undeformed Shape back. The special thing about elastomers is that their elasticity is not on attractions between based on changing atomic distances, but one static-dynamic balance between order and entropy represents. The elastomer therefore stores no tension energy in itself, but radiates the supplied during stretching Energy as heat and increases its instead inner order. Needed for a renewed contraction Therefore, the elastomer, the supply of energy, which, for example, by Brownian molecular motion extracts the ambient heat. Generally, such elastomers are in terms of their properties relatively flexibly adjustable, so that with such elastomers in particular a large occurring in motor vehicles Temperature range can be easily covered. In addition, elastomers are relatively inexpensive materials their elasticity and thus their damping behavior over can receive a long period of time.
Bei einer vorteilhaften Weiterbildung der erfindungsgemäßen Lösung, weist der als Außensechskant ausgebildete Außenmehrkant drei Radialeinschnitte auf, die jeweils an nicht direkt zueinander benachbarten Kanten des Außensechskants angeordnet sind. Derartige Einschnitte erleichtern die Montage der Innenwelle mit dem darauf angeordneten Dämpfungselement in der Außenwelle erheblich, da sie ein zumindest geringfügiges radiales Zusammendrücken des Dämpfungselements beim Einführvorgang in die Außenwelle ermöglichen. Gleichzeitig verbessern derartige Einschnitte auch das Dämpfungsverhalten an sich, da sich die durch die jeweiligen Einschnitte voneinander getrennten Abschnitte des Dämpfungselements unabhängig voneinander verformen können und die Einschnitte eine Schwingungsübertragung zwischen den einzelnen durch diese abgetrennten Abschnitte verhindern.In an advantageous development of the solution according to the invention, has the outside hexagonal external polygon three radial incisions, which are each arranged on not directly adjacent to each other edges of the hexagon. Such cuts facilitate the assembly of the inner shaft with the damping element arranged thereon in the outer shaft considerably, since they allow at least slight radial compression of the damping element during the insertion process in the outer shaft. At the same time, such incisions also improve the damping behavior per se, since the portions of the damping element which are separated from one another by the respective incisions can deform independently of one another and the incisions prevent oscillation transmission between the individual sections separated by the latter.
