Description

Malteserkreuz-Getriebe Die Erfindung betrifft ein Malteserkreuz-Getriebe mit mindestens einem Treiber an einer Getriebekette, die über mindestens ein Umlenkrad so geführt ist, daß sie den Treiber radial in das Malteserkreuz einführt und ausführt.Maltese cross gear The invention relates to a Maltese cross gear with at least one driver on a gear chain that has at least one pulley is guided so that it introduces and executes the driver radially in the Maltese cross.

Malteserkreuz-Getriebe dieser Art sind bekannt. Der Treiber sitzt bei diesen bekannten Getrieben an einer Kette, die im wesentlichen innerhalb des Malteserkreuzes liegt, und greift von innen in die nach innen radial offenen Schlitze des Malteserkreuzes ein. Bei dieser Konstruktion ist es, wenn überhaupt, nur sehr umständlich, Schaltschritte zu erreichen, die größer als 180° sind. Die Kette müßte dann nämlich über einen solchen Winkelbereich mittels einer Vielzahl von Abstützungen auf dem Radius geführt werden, auf den die Schlitze des Malteserkreuzes münden.Maltese cross gears of this type are known. The driver is sitting in these known transmissions on a chain which is essentially within the Maltese cross lies, and engages from the inside into the radially inwardly open slots of the Maltese cross. With this construction it is only very much, if at all awkward to achieve switching steps that are greater than 180 °. The chain should then namely over such an angular range by means of a large number of supports be guided on the radius on which the slots of the Maltese cross open.

Aufgabe der Erfindung ist es demgegenüber, ein Getriebe zu schaffen, mit dem in einfacher Weise Schaltschritte von über 180° erzielt werden können.The object of the invention, on the other hand, is to create a transmission with which switching steps of over 180 ° can be achieved in a simple manner.

Zur Lösung dieser Aufgabe ist das Getriebe eingangs genannter Art dadurch gekennzeichnet, daß die Getriebekette zwischen zwei Umlenkrädern radial zum Malteserkreuz hin um ein koaxial zum Malteserkreuz liegendes Umlenkrad und zwischen zwei Umlenkrädern radial vom Malteserkreuz fort geführt ist.To solve this problem, the transmission of the type mentioned at the beginning characterized in that the gear chain between two deflecting wheels is radial towards the Maltese cross around a deflection wheel lying coaxially to the Maltese cross and between two pulleys is carried out radially from the Maltese cross.

Der Schaltwinkel wird bei dieser Konstruktion in einfacher Weise durch die relative Lage der Punkte zwischen den Umlenkräderpaaren zueinander bestimmt, durch die die Getriebekette geführt ist.The switching angle is in this construction in a simple manner determines the relative position of the points between the deflection wheel pairs to one another, through which the gear chain is guided.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Die Zeichnung zeigt ein Malteserkreuz 10 mit drei im Winkelabstand 120° voneinander liegenden Schlitzen 41. Eine Getriebekette 2 trägt einen Treiber 11 und läuft über sechs Räder 3, 4, 5, 6, 7 und B. Das Rad 6 kann entfallen, wenn die Kette auf dem Weg 9 geführt wird. Bei dieser Anordnung ist der Schrittwinkel des Malteserkreuzes 240°; bei - wie üblich - konstanter Laufgeschwindigkeit der Getriebekette 2 erhält das Malteserkreuz 10 beim Schreiten eine konstante Winkelgeschwindigkeit.The drawing shows a Maltese cross 10 with three slots 41 at an angular distance of 120 ° from one another. A gear chain 2 carries a driver 11 and runs over six wheels 3, 4, 5, 6, 7 and B. The wheel 6 can be omitted if the chain is used is guided on path 9. With this arrangement, the step angle of the Maltese cross is 240 °; with - as usual - constant running speed of the gear chain 2 , the Maltese cross 10 receives a constant angular speed when walking.
