Description

Es sind bereits Zweiganggetriebe vorgeschlagen worden, die als Umlaufrädergetriebe ausgeführt sind, bei denen durch Abbremsen eines Gliedes des Umlaufrädergetriebes eine Übersetzung ins Schnelle erfolgt, während der direkte Gang durch eine Freilaufkupplung bewerkstelligt wird. Solche Getriebe waren bisher für Kraftfalirzeuge nur bedingt brauchbar, weil der direkte Gang nur mit Freilaufwirkung gefahren werden konnte.Two-speed transmissions have already been proposed as epicyclic gears are executed in which by braking a member of the epicyclic gear a Translation into high speed takes place, while the direct gear is accomplished by an overrunning clutch will. Such transmissions were previously only of limited use for Kraftfalirzeuge, because the direct gear only with freewheel effect could be driven.

Durch die Erfindung soll dieser Nachteil behoben werden. Dies geschieht erfindungsgemäß dadurch, daß das Getriebe mit einer an sich bekannten Sperrvorrichtung für den Freilauf versehen wird, und daß. diese Sperrvorrichtung mit der Bremsbedienungsvorrichtung so verbunden wird, daß eine falsche Bedienung unmöglich ist.The invention is intended to remedy this disadvantage. This is done according to the invention in that the transmission with a known locking device for the Freewheel is provided, and that. this locking device with the brake operating device is connected so that incorrect operation is impossible.

Die Abbildung zeigt eine Ausführungsform der Erfindung. Mit 1 ist ein Umlaufräderwechselgetriebe bezeichnet, dessen 'eines Sonnenrad 2 durch eine Bremsvorrichtung 3 in an sich bekannter Weise abgebremst werden kann. Zwischen dem mit der treibenden Welle 4 verbundenen Umlaufräderträger und dem mit der getriebenen Welle S verbundenen Zentralrad ist eine Freilaufkupplung 6 angeordnet, die durch eine Blockierungsvorrichtung 7 an sich bekannter Art gesperrt werden kann. Der Bedienungshebel 8 der Bremsvorrichtung 3, welcher der Gangschalthebel ist, und der Bedienungshebel 9 der Blockierungsvorrichtung 7 sind miteinander verbunden, und zwar so, daß bei eingeschaltetem Schnellgang und in der Mittelstellung der Freilauf in Wirkung ist, während er in der anderen Endstellung blockiert ist.The figure shows an embodiment of the invention. With 1 is a planetary gear change gear denotes whose 'one sun gear 2 is braked by a braking device 3 in a manner known per se can. Between the planetary gear carrier connected to the driving shaft 4 and the an overrunning clutch 6 is arranged with the central gear connected to the driven shaft S, which can be blocked by a blocking device 7 of a known type. The operating lever 8 of the braking device 3, which is the gear shift lever, and the operating lever 9 of the blocking device 7 are connected to one another, and so that when the overdrive is switched on and in the middle position, the freewheel is in effect while it is blocked in the other end position.

Die Wirkungsweise ist folgende: Befindet sich der Bedienungshebel 8 in der einen, z. B.. linken, Endstellung, in welcher das Sonnenrad 2 gebremst ist, so wird das andere Zentralrad und damit die getriebene Welle 5 in an sich bekannter Weise schneller angetrieben, wobei infolge der Freilaufkupplung 6 das mit der getriebenen Welle verbundene Zentralrad den mit der treibenden Welle verbundenen Umlaufräderträger überholt. Wird die Bremse 3 gelöst und der Bedienungshebel 8 in der Mittelstellung gehalten, so überträgt das Getriebe über die in Kuppelstellung befindliehe Freilaufkupplung 6 im Verhältnis 1 :1, wobei Freilaufwirkung eintreten kann. Wird der Bedienungshebel in die andere, z. B. rechte Endstellung gebracht, wobei die Bremsvorrichtung 3 gelöst bleibt, so wird die Blockierungsvorrichtung 7 an sich bekannter Art verstellt, so daß die Freilaufwirkung aufgehoben ist.The mode of operation is as follows: If the operating lever 8 is in the one, e.g. B. left, end position in which the sun gear 2 is braked, so the other central gear and thus the driven shaft 5 is driven faster in a manner known per se, as a result of the overrunning clutch 6, the central gear connected to the driven shaft the planetary gear carrier connected to the driving shaft is overtaken. If the brake 3 is released and the operating lever 8 in held in the middle position, the transmission transmits via the coupling position One-way clutch 6 in a ratio of 1: 1, freewheeling effect can occur. If the control lever is in the other, z. B. brought right end position, the braking device 3 remains released, so the Blocking device 7 adjusted per se known type, so that the freewheeling effect is canceled is.

Die Anordnung nach der Erfindung gestattet also, die in der Einleitung erwähnten Schnellganggetriebe auch für Kraftfalirzeuge verwendbar zu machen, und verhindert Betriebsstörungen durch eine falsche Bedienung.The arrangement according to the invention thus allows those mentioned in the introduction To make overdrive transmission usable for Kraftfalirzeuge, and prevents breakdowns by incorrect operation.
