Ein weiteres Problem bei der Verwendung des Abstandselements besteht darin, dass es eine axial fixierte Einbaulauge innerhalb der Tragfeder während seiner Betriebsdauer beibehalten sollte.One Another problem with the use of the spacer element consists in that there is an axially fixed mounting eye within the suspension spring during its Operating time should be maintained.
Die Aufgabe der vorliegenden Erfindung besteht in der Realisierung eines Federträgers mit einer Zusatzfeder, wobei die Zusatzfeder eine radiale Abstützung aufweist, jedoch gleichzeitig auch bei radial sehr kleinen Bauräumen einsetzbar ist.The Object of the present invention consists in the realization of a spring support with an additional spring, wherein the additional spring has a radial support, but at the same time also be used with radially very small spaces is.
Erfindungsgemäß besteht eine erste Lösung darin, die Außenkontur mit einem Schraubenprofil entsprechend der Steigung der Tragfeder ausgeführt ist.According to the invention a first solution in it, the outer contour with a screw profile corresponding to the pitch of the suspension spring is executed.
Damit wird eine partielle axiale Stauchung der Zusatzfeder vermieden und eine gleichmäßig Vorspannung zwischen den Windungen der Tragfeder erreicht.In order to a partial axial compression of the auxiliary spring is avoided and a uniform preload reached between the turns of the suspension spring.
Eine weitere erfindungsgmäße Lösung zeichnet sich dadurch aus, dass die Zusatzfeder mit Längenabschnitten mit verschiedenen Durchmessern ausgeführt. Aufgrund dieser Ausgestaltung findet ein belastungsabhängiges Eindringen der Zusatzfeder in die Windungen der Tragfeder statt, so dass eine auch eine belastungsabhängige Beeinflussung der Federkraftkennlinie des Federträgers vorliegt. Bei einer kleineren Belastung kommt auch nur ein Längenabschnitt der Zusatzfeder mit der Tragfeder in Kontakt, während bei maximaler Belastung zusätzlich u. U. noch weitere Längenabschnitt in die Windungen der Tragfeder eingreifen. Der große Vorteil besteht darin, dass die Tragfeder für die Zusatzfeder die Funktion einer Armierung übernimmt, ohne dass diese bereits in der Zusatzfeder als Bauteil vorhanden sein muss.A further erfindungsgmäße solution draws characterized in that the additional spring with length sections with different Diameters executed. Due to this configuration is a load-dependent intrusion the additional spring takes place in the turns of the suspension spring, leaving a also a burden-dependent Influencing the spring force characteristic of the spring carrier is present. At a smaller load comes only a length the auxiliary spring in contact with the suspension spring, while at maximum load additionally u. U. even more length section engage in the turns of the suspension spring. the big advantage is that the suspension spring for the auxiliary spring the function a reinforcement takes over, without these already present in the auxiliary spring as a component have to be.
Dabei ist für eine erste Variante vorgesehen, dass der Abstand zwischen den federnden Windungen der Tragfeder bei einem Kontakt der Zusatzfeder mit der Tragfeder kleiner als ein Grenzextrusionsmass der Zusatzfeder. Die Tragfeder muss nicht auf ihr Blockmass gestaucht werden, um eine Armierungsfunktion zu übernehmen. Verschiedene Werkstoffe haben jeweils ein eigenes Grenzextrusionsmass, unterhalb dessen ein Eindringen von Werkstoff in Spalte nicht mehr auftritt. Dieser Effekt hat zur Folge, dass die Tragfeder trotz der federnden Windungen für die Zusatzfeder wie eine geschlossene Hülle wirkt und eine ideale radiale Abstützung bildet.there is for a first variant provided that the distance between the resilient Windings of the suspension spring at a contact of the auxiliary spring with the Suspension spring smaller than a limit extrusion dimension of the additional spring. The Suspension spring does not have to be compressed to its block size to one Reinforcing function to take over. Different materials each have their own limit extrusion size, below which penetration of material in column is no longer possible occurs. This effect has the consequence that the suspension spring despite the resilient turns for the auxiliary spring acts like a closed shell and an ideal radial support forms.
Alternativ besteht die Möglichkeit, dass die Zusatzfeder radial in den Bereich zwischen den Windungen der Tragfeder verformt wird. Damit werden zwei Ziele erreicht. Zum einen liegt eine radiale Abstützung der Zusatzfeder durch die Windungen der Tragfeder vor und zum anderen werden federnde Windungen der Tragfeder durch das Eindringen der Zusatzfeder in den Windungsbereich der Tragfeder zu blockierten Windungen, wodurch sich die Federrate des Federträgers merklich vergrößern lässt.Alternatively, there is the possibility that the additional spring radially into the area between the Win the suspension spring is deformed. This achieves two goals. On the one hand, there is a radial support of the auxiliary spring through the turns of the suspension spring and on the other spring elastic windings of the suspension spring by the penetration of the auxiliary spring in the winding region of the suspension spring to blocked turns, which can increase the spring rate of the spring carrier noticeably.
