Description

Es sind stufenlose Getriebe der verschiedensten Arten bekannt. Der Gegenstand vorliegender Erfindung bezieht sich auf ein stufenloses Getriebe, welches hauptsächlich für kleinere Übertragungseinrichtungen, etwa für Spielzeug-gedacht ist.Various types of continuously variable transmissions are known. Of the The present invention relates to a continuously variable transmission which mainly intended for smaller transmission devices, e.g. for toys is.

Zwei Zahnräder von verschiedenem Durchmesser ergeben ineinandergreifend stets verschiedene Umdrehungsza'hlen, die in einem bestimmten Verhältnis stehen.Two gears of different diameters result in interlocking always different numbers of revolutions, which are in a certain ratio.

Wenn man den Durchmesser während der Umdrehungen verändern und doch die Räder stets ineinandergreifen lassen könnte, so würden sich auch die Umdrehungen entsprechend ändern.If you change the diameter during the revolutions and yet If the wheels could always mesh, so would the revolutions change accordingly.

Dies ist technisch nicht möglich, jedoch kann man zwei Kegel (s. Zeichnung) gegeneinandersetzen. Im Querschnitt stehen diese Kegel an jeder Stelle in einem anderen Durchmesserverhältnis. Direkt ineinandergreifend könnten sie sich nicht drehen. Es muß ein Zwischenraum gelassen werden. Nur an der Stelle, deren Durchmesserverhältnis gewünscht ist, ist die Verbindung herzustellen. Um das Umdrehungsverhältnis schnell ändern zu können, muß das Verbindungsstück, Hartgummirad, Hartgummiring, Stahlbandring usw. rasch verschiebbar sein.This is not technically possible, but you can use two cones (see drawing) oppose each other. In the cross-section, these cones stand in one place at every point different diameter ratio. They could not interlock directly turn. There must be a space left. Only at the point of their diameter ratio connection is required. To get the revolution ratio fast To be able to change, the connector, hard rubber wheel, hard rubber ring, steel band ring must be used etc. can be moved quickly.

Die Wirkungsweise ist unter Hinweis auf das in der Zeichnung dargestellte Ausführungsbeispiel folgende: Auf der mit dem Motor fest verbundenen treibenden Achee i sowie der getriebenen Achse 2 sitzen je ein Kegel mit zueinander entgegengesetzten Grundflächen, aber parallelen Achsen so, daß ein schmaler Spalt zwischen ihnen frei bleibt. In diesen greift ein Hartgummiring 4, welcher um den auf der getriebenen Achse 2 sitzenden Kegel umläuft. Die aufgerawhten, bzw. gerillten Kegel drücken beide gegen den Ring 4, wodurch an dieser Stelle eine Verbindung beider Kegel ''hergestellt wird. Wenn sich nun der mit dem Motor verbundene Kegel dreht, zieht er den Hartgummiring4 mit, und dieser wiederum überträgt die rotierende Bewegung auf den anderen Kegel. Bei schnellen Umdrehungen genügt das geringste Kippen des Ringes 4 aus der Senkrechten der Achsenebene, und er wandert so lange aus, bis er wieder in der Senkrechten steht. Die Gabel 3, die das Kippen bewirkt, muß nur stets in dem durch die Achsenebene geteilten Stück des Ringes liegen, von dem der Ring durch die Kegel wegwandert. Je nach dem gewünschten Umdrehungsverhältnis muß man den Ring ,4 an die betreffende Stelle wandern lassen.The mode of operation is with reference to that shown in the drawing Embodiment following: On the driving firmly connected to the engine Achee i and the driven axle 2 each have a cone with opposite sides Base planes but parallel axes so that a narrow gap is free between them remain. In this engages a hard rubber ring 4, which is driven around the Axis 2 seated cone revolves. Press the roughened or grooved cones both against the ring 4, whereby a connection between the two cones '' is established at this point will. When the cone connected to the motor turns, it pulls the hard rubber ring4 with, and this in turn transmits the rotating movement to the other cone. With fast revolutions, the slightest tilting of the ring 4 from the vertical is sufficient the axial plane, and it drifts out until it is perpendicular again. The fork 3, which causes the tilting, must only always be in the plane through the axis split piece of the ring, from which the ring migrates through the cones. Depending on the desired rotation ratio, you have to put the ring, 4 on the relevant one Let the place wander.
