Abstract
Description
Die Erfindung betrifft eine flexible Welle für Spielzeugmodelle gemäß der Gattung des Anspruches 1.The invention relates to a flexible shaft for toy models according to the preamble of claim 1.
Zur Kraftübertragung in Spielzeugmodellen oder entsprechenden Modellanordnungen werden für unterschiedliche Zwecke, beispielsweise für den Antrieb oder für die Lenkung eines Fahrzeuges, Wellen verwendet. Zur Lenkung von Spielzeugmodellen ist es bekannt, eine aus einem Draht bestehende und in einem biegsamen Führungsrohr gelagerte Lenkwelle mit der Lenksäule des Fahrzeuges auf der einen Seite und mit einer Kurbel auf der anderen Seite zu verbinden. Lenksäule und Kurbel weisen zu diesem Zweck Kupplungsstücke auf, in denen die Lenkwelle fest eingeklemmt ist. Eine solche Vorrichtung ist somit fester Bestandteil eines fertigen Spielzeugmodells und demzufolge für eine universelle Anwendung als Bauteil eines Konstruktionsbaukastens nicht geeignet. Neben der Drehmomentübertragung sind in Spielzeugmodellen häufig Funktionen erforderlich, bei denen auch Druck- und Zugkräfte zu übertragen sind. Für Zugkräfte ist es bekannt, Bowdenzüge zu verwenden, die allerdings nicht für die Übertragung von Druckkräften geeignet sind.Shafts are used for power transmission in toy models or corresponding model arrangements for different purposes, for example for driving or steering a vehicle. For the steering of toy models, it is known to connect a steering shaft consisting of a wire and mounted in a flexible guide tube to the steering column of the vehicle on one side and to a crank on the other side. For this purpose, the steering column and crank have coupling pieces in which the steering shaft is firmly clamped. Such a device is thus an integral part of a finished toy model and therefore not suitable for universal use as a component of a construction kit. In addition to the torque transmission, functions are often required in toy models that also have to transmit pressure and tensile forces. For tensile forces it is known to use Bowden cables, which, however, are not suitable for the transmission of compressive forces.
Der Erfindung liegt die Aufgabe zugrunde, eine flexible Welle für Spielzeugmodelle zu schaffen, die universell einsetzbar und insbesondere zur Drehmomentübertragung und zur Übertragung von Zug- und Druckkräften geeignet ist.The invention has for its object to provide a flexible shaft for toy models that can be used universally and is particularly suitable for torque transmission and transmission of tensile and compressive forces.
Die Lösung dieser Aufgabe wird mit den Merkmalen des Anspruches 1 erreicht. An beiden Enden der flexiblen Welle sind Anschlußelemente angeordnet, die über eine Vielzahl von starr miteinander verbundenen Ringelementen aus Kunststoff flexibel verbunden sind. Die Ringelemente haben dabei gegenüber einer stabförmigen Welle den Vorteil, daß einerseits eine hohe Flexibilität der Welle erhalten wird, während andererseits auch ein hohes Drehmoment übertragen werden kann. Die vorzugsweise in einem Winkel von 90° zueinander versetzt angeordneten Ringelemente bringen den Vorteil, daß die flexible Welle in jeder Richtung gleichermaßen biegsam ist und in jeder Lage ein hohes Drehmoment übertragen kann.This object is achieved with the features of claim 1. At both ends of the flexible shaft connection elements are arranged, which are flexibly connected via a plurality of rigidly connected ring elements made of plastic. The ring elements have the advantage over a rod-shaped shaft that on the one hand a high flexibility of the shaft is obtained, while on the other hand a high torque can also be transmitted. The ring elements, which are preferably offset at an angle of 90 ° to one another, have the advantage that the flexible shaft is equally flexible in every direction and can transmit a high torque in any position.
Die von den Ringelementen umschlossenen Ringebenen liegen bei gerade ausgerichteter Welle vorzugsweise auf deren Mittelachse. Dadurch erhält man eine homogene Drehmomentübertragung, d. h. jedes Ringelement wird bei der Drehmomentübertragung gleichermaßen beansprucht. Beim Biegen der flexiblen Welle ändert sich dagegen die Biegebeanspruchung in den einzelnen Ringelementen je nach Stellung der Welle.The ring planes enclosed by the ring elements preferably lie on their central axis when the shaft is aligned. This gives a homogeneous torque transmission, i. H. each ring element is equally stressed during torque transmission. When the flexible shaft is bent, however, the bending stress in the individual ring elements changes depending on the position of the shaft.
Die flexible Welle ist vorzugsweise im Spritzgußverfahren aus Kunststoff einstückig hergestellt, wobei die Verbindungsstellen zwischen benachbarten Ringelementen Kreuzungspunkte bilden.The flexible shaft is preferably made in one piece from plastic by injection molding, the connection points between adjacent ring elements forming intersection points.
Die in Reihe angeordneten Ringelemente können teilweise oder vollständig von einem Führungsrohr umschlossen sein, wodurch sich höhere Druckkräfte und höhere Drehmomente problemlos übertragen lassen. Ein Führungsrohr oder dgl. ist auch dann erforderlich, wenn bei gebogener Welle Zugkräfte übertragen werden sollen.The ring elements arranged in series can be partially or completely enclosed by a guide tube, as a result of which higher compressive forces and higher torques can be transmitted without problems. A guide tube or the like is also required if tensile forces are to be transmitted when the shaft is bent.
Zur Verbindung der flexiblen Welle mit einer Antriebswelle oder einer Abtriebswelle besitzt diese an ihren Anschlußstücken jeweils stirnseitig befindliche Kupplungsstücke.To connect the flexible shaft to an input shaft or an output shaft, the latter has coupling pieces located on the end faces of each of its connecting pieces.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with reference to an embodiment shown in the drawing.

Die flexible Welle ist einstückig aus Kunststoff im Spritzgießverfahren hergestellt, wobei je nach Anforderungen und Anwendungsgebiet ein entsprechend elastischer oder härterer Kunststoff verwendet werden kann. Um eine kraftschlüssige Verbindung mit hier nicht dargestellten Antriebswellen und Abtriebswellen herstellen zu können, besitzt die flexible Welle an den Anschlußelementen 1,2 stirnseitig angeordnete Kupplungsstücke 7,8, die so profiliert sind, daß eine Drehmomentübertragung und auch eine Übertragung von Druck- und Zugkräften möglich ist.The flexible shaft is made in one piece from plastic using the injection molding process, and depending on the requirements and field of application, a correspondingly elastic or harder plastic can be used. In order to be able to establish a non-positive connection with drive shafts and output shafts (not shown here), the flexible shaft has coupling pieces 7, 8 on the end faces on the connecting
