Description

Strangförmige Zugfeder aus Gummi od. dgl. Die Erfindung bezieht sich auf strangförmige Zugfedern aus Gummi od. dgl., beispielsweise für verstellbare Keilriemenscheiben. Die Erfindung bezweckt eine leicht lösbare, für den Betrieb jedoch sichrere Befestigung der Federenden.Cord-shaped tension spring made of rubber or the like. The invention relates on string-shaped tension springs made of rubber od. Like., For example for adjustable V-belt pulleys. The invention aims at an easily detachable, for operation but more secure fastening of the spring ends.

Bei Sportgeräten ist es bereits bekannt, an ihren Enden mit Wülsten versehene elastische Bänder in einen Längskanal der Griffstücke einzuhängen. Bei einem anderen bekanuten Sportgerät wird ein Gummischlauch in der konischen Bohrung eines Kugelgriffes durch einen eingetriebenen Kegel befestigt. Bei diesen bekannten Ausführungen sind die bei der Befestigung der Gummifeder mitwirkenden Teile nicht fest mit der Gummifeder verbunden.In the case of sports equipment, it is already known to have beads at their ends to hang provided elastic bands in a longitudinal channel of the handle pieces. at Another well-known piece of sports equipment is a rubber hose in the conical bore a ball handle attached by a driven cone. With these well-known The parts involved in fastening the rubber spring are not versions firmly connected to the rubber spring.

Demgegenüber zeichnet sich der Gegenstand der Erfindung .dadurch aus, daß die Füllstücke festhaftend mit den Federenden verbunden und mit einer von außen zugänglichen Aussparung versehen sind. Die feste Verbindung zwischen dem Füllstück und dem zugehörigen Federende verhindert, daß das Füllstück verlorengehen kann, was von besonderer Bedeutung ist, wenn eine Zugfeder an einem bereits eingebauten Getriebe ausgewechselt werden muß, da hierbei die Ausnehmungen für die Federenden oft nur schwer zugänglich sind. Auch die betrieblichen Eigenschaften der Gummizugfeder werden verbessert, da die angehafteten Füllstücke eine zu starke Verformung der Federenden ausschalten. Auch ermöglichen die von außen zugänglichen Aussparungen an den Füllstücken die erleichterte Verwendung von Montagewerkzeugen, da die Federenden zur Montage oder Reparatur mit einfachen Werkzeugen erfaßt werden können, die in die rohr- oder ringförmigen Versteifungen der Federenden eingeführt werden.In contrast, the subject matter of the invention is characterized by that the filler pieces are firmly connected to the spring ends and to one from the outside accessible recess are provided. The fixed connection between the filler piece and the associated spring end prevents the filler piece from being lost, which is of particular concern when a tension spring is attached to an already installed Gear must be replaced, as this is the recesses for the spring ends are often difficult to access. Also the operational properties of the elastic tension spring are improved because the adhered filler pieces cause excessive deformation of the Switch off spring ends. The recesses that are accessible from the outside also make it possible the easier use of assembly tools on the filler pieces, since the spring ends for assembly or repair can be recorded with simple tools that are in the tubular or annular stiffeners of the spring ends are introduced.

In weiterer Ausgestaltung der Erfindung wind vorgeschlagen. die Federenden ganz oder zum Teil zähhart zu gestalten, was z. B. durch erhöhten Schwefelzuschlag bei Federn ans Gummi oder aber auch durch Fremdstoffbeimischungen, wie Gewebefasern, erzielt werden kann. Hierdurch wird eine besonders innig-e Verbindung zwischen den Füllstücken und den Federenden erzielt, und es besteht auch nicht die Gefahr, daß die die Füllstücke umschließenden Teile der Feder zu stark verformt werden.In a further embodiment of the invention is proposed. the spring ends to make wholly or partially tough, which z. B. by increased sulfur surcharge in the case of feathers on rubber or through the addition of foreign substances, such as fabric fibers, can be achieved. This creates a particularly intimate connection between the Filler pieces and the spring ends achieved, and there is also no risk that the parts of the spring surrounding the filler pieces are deformed too much.

Ausführungsbeispiele der Erfindung sind in der Zeichnung dargestellt.Embodiments of the invention are shown in the drawing.

Fig. 1 zeigt eine strangförmige Gummizugfeder mit rundem Querschnitt; Fig. 2 zeugt das obere Ende der in Fig. 1 dargestellten Gummizugfeder in Seitenansicht; Fig. 3 zeigt die Einführung des Federendes in die Ausnehmung eines Verbindungsteils. Der eigentliche Federkörper der Gummizugfeder ist mit 1 und die verdickten Federenden sind mit 2 bezeichnet, die ihrerseits keilförmig verlaufende Flächen 2' aufweisen. Die Federenden 2 sind mit rohrförmigen Füllstücken 3 aus Metall versehen. Diese sind in Bohrungen der Federenden 2 eingesetzt und fest haftend, z. B. auf dem Wege der Vulkanisation, mit den Federenden 2 verbunden. In Fig. 3 ist das Teil, mit dem das Federende verbunden werden soll, mit 4 bezeichnet. Seine Ausnehmungen 4' weisen ebenfalls keilförmig verlaufende Flächen 5 auf, so daß sich die Federenden 2 bzw. deren Flächen 2' mit der Belastung des Federkörpers 1 gegen die Flächen 5 anpressen. Die Gummizugfedern können auch mittelbar mit den gegeneinander abzufedernden Teilen verbunden werden.Fig. 1 shows a cord-shaped elastic tension spring with a round cross-section; FIG. 2 shows the upper end of the elastic tension spring shown in FIG. 1 in a side view; Fig. 3 shows the introduction of the spring end into the recess of a connecting part. The actual spring body of the elastic tension spring is with 1 and the thickened spring ends are denoted by 2, which in turn have wedge-shaped surfaces 2 '. The spring ends 2 are provided with tubular filler pieces 3 made of metal. These are inserted into holes in the spring ends 2 and firmly adhered, for. B. on the way vulcanization, connected to the spring ends 2. In Fig. 3 is the part with which the end of the spring is to be connected, denoted by 4. Its recesses 4 'point also wedge-shaped surfaces 5, so that the spring ends 2 or the surfaces 2 'of which press against the surfaces 5 with the load of the spring body 1. The elastic tension springs can also be indirectly connected to the parts to be cushioned against one another get connected.
