Es ist also insbesondere nicht möglich, einen nennenswerten Einfluss auf das Feder- bzw. Dämpfverhalten des Federspeichers zu nehmen. Es wäre wün schenswert, hier einen höheren Freiheitsgrad zu haben, um beispielsweise auch einen speziellen Verlauf der Federkennlinie vorgeben zu können.It is therefore not possible in particular a significant influence on the spring or damping behavior to take the spring store. It would be desirable, here a higher degree of freedom to have, for example, a special course of the spring characteristic to pretend.
Aufgabe der ErfindungObject of the invention
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, ein Triebrad der eingangs genannten Art so fortzubilden, dass es möglich wird, die Feder- und/oder Dämpfcharakteristik des Federspeichers zu beeinflussen. Dabei soll das Triebrad möglichst platzsparend konzipiert sein und nur einen möglichst geringen Bauraum einnehmen.Of the The present invention is therefore based on the object, a drive wheel of the type mentioned at the beginning in such a way that it becomes possible to the spring and / or damping characteristics of the spring store to influence. The drive wheel should be as possible save space and take only the smallest possible space.
Zusammenfassung der ErfindungSummary of the invention
Die Lösung dieser Aufgabe durch die Erfindung ist dadurch gekennzeichnet, dass der Federspeicher des Triebrads mindestens zwei separate Federn aufweist.The solution this object by the invention is characterized in that the spring accumulator of the drive wheel at least two separate springs having.
Diese sind bevorzugt in Reihe hintereinander geschaltet. Ferner kann zwischen den mindestens zwei Federn mindestens ein Zwischenstück angeordnet sein, an dem mindestens zwei Federn drehfest angeordnet sind.These are preferably connected in series one behind the other. Furthermore, between the at least two springs arranged at least one intermediate piece be, on which at least two springs are arranged rotationally fixed.
Um einen möglichst hohen Einfluss auf die Feder- und/oder Dämpfcharakteristik des Federspeichers zu nehmen, haben die mindestens zwei Federn vorzugsweise unterschiedliche Größen und/oder Bauarten.Around one possible high influence on the spring and / or damping characteristics of the spring accumulator preferably, the at least two springs have different ones Sizes and / or designs.
Zunächst bietet es sich an, die Wirkdurchmesser der mindestens zwei Federn unterschiedlich groß zu gestalten. Weiter hat es sich besonders bewährt, wenn eine Feder als Bogenfeder oder Bogenfederpaket ausgeführt ist. Eine oder die andere Feder ist bevorzugt als Schraubenfeder ausgeführt. Die Schraubenfeder ist gemäß einer bevorzugten Ausführungsform schenkellos ausgebildet.At first offers It is about to make the effective diameter of at least two springs of different sizes. Furthermore, it has proven particularly useful if a spring is designed as a bow spring or bow spring package. One or the other spring is preferably designed as a helical spring. The coil spring is according to one preferred embodiment formed thighless.
Mindestens eine Feder, vorzugsweise eine Schraubenfeder, kann vorgespannt montiert sein.At least a spring, preferably a helical spring, can be mounted prestressed be.
Das mindestens eine Zwischenstück kann sowohl gegenüber dem Laufmantel als auch gegenüber der Nabe rotatorisch gelagert sein. Zwischen dem Zwischenstück und dem Laufmantel kann ein Lager, insbesondere ein Radiallager, angeordnet sein. Weiter kann zwischen dem Zwischenstück und der Nabe ein Lager, insbesondere ein Radiallager, angeordnet sein. Das Lager ist bevorzugt hier ein Gleitlager. Es kann als zwischen die Bauteile eingeschobene Gleitlagerlaufbuchse ausgeführt sein. Es ist aber auch möglich, lediglich die Materialpaarung der reibend aneinander liegenden Bauteile so zu wählen, dass von den Teilen eine Gleitlagerfunktion ausgeübt werden kann. Zwischen dem Laufmantel und der Nabe kann ebenfalls ein Lager, insbesondere ein kombiniertes Radial- und Axiallager, angeordnet sein. Dieses Lager ist bevorzugt als Wälzlager ausgebildet, wobei besonders bevorzugt ein Nadellager oder ein Kugellager zum Einsatz kommt.The at least one intermediate piece can be mounted rotationally both with respect to the running jacket and with respect to the hub. A bearing, in particular a radial bearing, can be arranged between the intermediate piece and the running jacket. Further, between the intermediate piece and the hub, a bearing, in particular a radial bearing, be arranged. The bearing is preferred here a plain bearing. It can be designed as inserted between the components plain bearing sleeve. But it is also possible to choose only the combination of materials rubbing against each other lying components so that a slide bearing function can be exercised by the parts. A bearing, in particular a combined radial and thrust bearing, can likewise be arranged between the running jacket and the hub. This bearing is preferably designed as a rolling bearing, wherein a needle bearing or a ball bearing is particularly preferably used.
Das Zwischenstück kann eine Aufnahme für die Bogenfeder oder das Bogenfederpaket bilden, wobei die Bogenfeder oder das Bogenfederpaket weiterhin in der Aufnahme eines Dämpferkäfigs angeordnet sein kann. Zwischen dem Dämpferkäfig und der Nabe kann eine Rutschkupplung wirksam angeordnet sein, wodurch im Falle einer Überlast ein Durchrutschen möglich wird.The connecting piece can take a picture for the Bow spring or the bow spring package form, the bow spring or the bow spring package is still arranged in the receptacle of a damper cage can be. Between the damper cage and the hub can be effectively arranged a slip clutch, whereby in case of overload Slipping possible becomes.
Mit der vorgeschlagenen Lösung wird es möglich, eine gezielte Einstellung der Feder- und/oder Dämpfcharakteristik des Federspeichers vornehmen zu können, was bei der vorbekannten Ausgestaltung mit nur einem Federelement im Federspeicher nicht möglich ist. Dies wird durch den Einsatz verschiedener Federelementtypen bzw. durch eine Verschaltung mehrerer verschiedener Federelementtypen bezüglich Federsteifigkeit bzw. Bauform erreichbar. Durch das erfindungsgemäße Konzept kann die Gesamtfedersteifigkeit und deren Verlauf in einem größeren Bereich variiert werden, als dies bei vorbekannten Lösungen der Fall ist. Es ist dabei auch die Realisierung einer nichtlinearen, z. B. einer abknickenden Federkennlinie möglich. Der zur Verfügung stehende Bauraum wird durch die bevorzugt vorgeschlagene Bauweise effizient und flexibel ausgenutzt.With the proposed solution will it be possible make a targeted adjustment of the spring and / or Dämpfcharakteristik the spring accumulator to be able to which in the previously known embodiment with only one spring element not possible in the spring accumulator is. This is achieved through the use of different spring element types or by an interconnection of several different spring element types in terms of Spring stiffness or design achievable. By the concept according to the invention Can the overall spring stiffness and its course in a larger area can be varied than is the case with previously known solutions. It is while also the realization of a nonlinear, z. B. a kinking Spring characteristic possible. The available standing space is due to the preferred proposed construction exploited efficiently and flexibly.
