Description
Die Erfindung betrifft eine Schraubenfederanordnung mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a coil spring assembly having the features of the preamble of
Im Hinblick auf einen großen Komfort müssen die Entstehung und/oder die Ausbreitung von Schwingungen oder Vibrationen in Kraftfahrzeugen möglichst eingeschränkt werden. Zwar ist es grundsätzlich möglich, durch konstruktive Maßnahmen am Fahrzeugmotor, insbesondere durch einen guten Massenausgleich, die vom Motor erzeugten Schwingungen vergleichsweise gering zu halten. Gleichwohl können bei einem Kolbentriebwerk, insbesondere bei geringerer Zylinderzahl, Drehschwingungen nicht vermieden werden. Um eine Übertragung dieser Drehschwingungen auf den Antriebstrang zu vermeiden, ist es grundsätzlich bekannt, zwischen Motor und Antriebstrang Drehschwingungsdämpfer, insbesondere in Form sogenannter Zwei-Massen-Schwungräder anzuordnen. Diese Drehschwingungsdämpfer bzw. Zwei-Massen-Schwungräder besitzen motorseitige und antriebstrangseitige Teile bzw. Schwungmassenkörper, die miteinander über Schraubendruckfedern antriebsmäßig gekoppelt sind, wobei die Schraubenfedern derart angeordnet sind, daß vor allem bei Zugbetrieb (Motor treibt das Fahrzeug) federnde Bewegungen zwischen Motorseite und Antriebstrangseite möglich sind.In view of a great comfort, the generation and / or the propagation of vibrations or vibrations in motor vehicles must be restricted as much as possible. Although it is in principle possible to keep the vibrations generated by the engine comparatively low by constructive measures on the vehicle engine, in particular by a good mass balance. Nevertheless, torsional vibrations can not be avoided in a piston engine, in particular with a smaller number of cylinders. In order to avoid transmission of these torsional vibrations to the drive train, it is basically known to arrange torsional vibration dampers, in particular in the form of so-called two-mass flywheels, between engine and drive train. This torsional vibration damper or two-mass flywheels have engine-side and drive train-side parts or flywheel mass, which are drivingly coupled to each other via helical compression springs, wherein the coil springs are arranged such that, especially in traction (engine drives the vehicle) resilient movements between the engine side and drive train side possible are.
Um große Federhübe ermöglichen zu können, sind die Schraubendruckfedern vorzugsweise kreisbogenförmig ausgebildet, d. h. die Längsachse der Schraubendruckfedern bildet einen Kreisbogen. Außerdem sind die Schraubendruckfedern in käfigartigen Aufnahmeräumen aufgenommen und geführt, die zwischen der Motorseite und der Antriebstrangseite des Drehschwingungsdämpfers bzw. zwischen den Schwungmassenkörpern des Zwei-Massen-Schwungrades ausgebildet sind. Die

Aufgabe der Erfindung ist es, bei einer Schraubenfederanordnung der eingangs angegebenen Art zu gewährleisten, daß die Innenfeder bei der Montage der Schraubenfederanordnung sicher in ihre Sollage innerhalb der Außenfeder gebracht und nachfolgend in der Sollage gehalten werden kann.The object of the invention is to ensure a coil spring assembly of the type specified that the inner spring can be safely placed in the assembly of the coil spring assembly in its desired position within the outer spring and subsequently held in the desired position.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of
Alternativ kann die Schraubenfederanordnung gemäß dem Anspruch 6 ausgebildet sein.Alternatively, the coil spring assembly may be formed according to claim 6.
Die Erfindung beruht auf dem allgemeinen Gedanken, an einem Ende der Federanordnung miteinander korrespondierende Durchmesseränderungen des Innendurchmessers der Außenfeder und des Außendurchmessers der Innenfeder vorzusehen, so daß die beiden Federn an dem vorgenannten Ende der Federanordnung anschlagartig zusammenwirken, wenn die Innenfeder innerhalb der Außenfeder ihre Sollage einnimmt. Dabei wird der Anschlag mit einer zur Endwindung benachbarten Windung der Außenfeder bewirkt.The invention is based on the general idea to provide at one end of the spring assembly mutually corresponding diameter changes of the inner diameter of the outer spring and the outer diameter of the inner spring, so that the two springs at the aforementioned end of the spring arrangement stop-like cooperate when the inner spring within the outer spring assumes its desired position , In this case, the stop is effected with a winding adjacent to the end turn of the outer spring.
Durch die Erfindung kann sicher verhindert werden, daß die Innenfeder zu weit in die Außenfeder eingeschoben wird. Andererseits bleibt die Lage der Innenfeder innerhalb der Außenfeder nach Unterbringung der Federanordnung im Stoß- bzw. Schwingungsdämpfer sicher erhalten, weil die Federanordnung mit ihren beiden Enden an relativ zueinander beweglichen Anschlägen des Stoß- bzw. Schwingungsdämpfers anliegt. By the invention can be reliably prevented that the inner spring is inserted too far in the outer spring. On the other hand, the position of the inner spring within the outer spring after placement of the spring assembly in the shock or vibration damper remains secure because the spring assembly rests with its two ends on relatively movable stops of the shock or vibration damper.
Da die Endwindungen der Federanordnung vorzugsweise in an sich bekannter Weise aneinander anliegen und dementsprechend nahezu federunwirksam sind, hat der verminderte Drahtquerschnitt der Außenfeder im Bereich der Endwindungen keinerlei unerwünschte Rückwirkung auf die Federcharakteristik der Federanordnung.Since the end turns of the spring assembly preferably abut each other in a conventional manner and are therefore almost spring ineffective, the reduced wire cross section of the outer spring in the end turns has no undesirable effect on the spring characteristic of the spring assembly.
Der verminderte Drahtquerschnitt wird vorzugsweise durch materialabtragende Bearbeitung der Außenfeder erzeugt, wobei vorteilhaft ist, daß diese Bearbeitung an der Außenseite der Außenfeder vorgenommen werden kann.The reduced wire cross-section is preferably produced by material-removing machining of the outer spring, wherein it is advantageous that this processing can be carried out on the outer side of the outer spring.
Im übrigen wird hinsichtlich bevorzugter Merkmale der Erfindung auf die Ansprüche sowie die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der eine bevorzugte Ausführungsform der Erfindung näher beschrieben wird.Moreover, reference is made with regard to preferred features of the invention to the claims and the following explanation of the drawing, with reference to a preferred embodiment of the invention will be described in more detail.
