Description
Die Erfindung betrifft eine Verbesserung und weitere Entwicklung des Umlaufrädergetriebes nach Patent 602 521, bei welchem durch Abbremsen eines Getriebeteiles das Getriebe ims Schnelle übersetzt wird, während der direkte Gang durch eine Freilaufkupplung in Verbindung mit einer Sperrvorrichtung bewerkstelligt wird.The invention relates to an improvement and further development of the planetary gear transmission according to patent 602 521, in which the transmission by braking a transmission part Ims is translated quickly, while the direct gear is through an overrunning clutch is accomplished in conjunction with a locking device.
Erfindungsgemäß besteht die Verbesserung darin, daß als Sperrvorrichtung eine Klauenkupplung mit schrägen Stirnflächen verwendet wird. Solche Klauenkupplungen sind an sich bekannt. Die Schräge der Klauen wird hierbei so gewählt, daß sie abgewiesen werden, solange sich die Freilaufkupplung im Überholungszustande befindet, und der Eingriff der Klauen erst dann erfolgen kann, wenn durch den Eingriff der Freilaufkupplung Gleichlauf der zu kuppelnden Wellen erreicht ist.According to the invention, the improvement is that a claw clutch is used as a locking device is used with sloping end faces. Such claw couplings are known per se. The slope of the claws will chosen so that they are rejected as long as the overrunning clutch is in Is in a state of overhaul and the claws can only then intervene when the engagement of the overrunning clutch achieves synchronization of the shafts to be coupled is.
Die Abbildung zeigt eine Ausführungsform der Erfindung. Mit 1 ist ein Umlaufrädergetriebe bezeichnet, dessen eines Zentralrad 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 5 verbundenen Zentralrad ist eine Freilaufkupplung 6 angeordnet.The figure shows an embodiment of the invention. With 1 is a planetary gear denotes whose one central wheel 2 can be braked by a braking device 3 in a manner known per se. Between the planetary gear carrier connected to the driving shaft 4 and the one with The central wheel connected to the driven shaft 5 is provided with an overrunning clutch 6.
Die treibende Welle 4 ist ferner mit Klauen 7 versehen, ini welche die Klauen einer auf der getriebenen Welle 5 verschiebbar, aber nicht drehbar angeordneten Klauenmuffe 8 eingreifen können. Diese Klauen haben in an sich bekannter Weise abgeschrägte Stirnflächen, deren Schräge so gewählt ist, daß die Klauen abgewiesen werden, solange sich die Freilaufkupplung 6 im Überholungszustande befindet. Der Bedienungshebel 9 der Klauenmuffe 8 und der Bedienungshebel 10 der Bremsvorrichtung 3 sind so miteinander verbunden, daß das Einrücken der Klauenmuffe 8 nur möglich ist, wenn vorher die den Schnellgang bewirkende Bremsvorrichtung 3 gelöst worden ist.The driving shaft 4 is also provided with claws 7, ini which the claws one on the driven shaft 5 slidably but not rotatably arranged claw sleeve 8 engage can. These claws have beveled end faces in a manner known per se, whose slope is chosen so that the claws are rejected as long as the Overrunning clutch 6 is in the overhaul condition. The operating lever 9 of the claw sleeve 8 and the operating lever 10 of the braking device 3 are connected to one another in such a way that that the engagement of the claw sleeve 8 is only possible if the braking device 3 causing the overdrive beforehand has been resolved.
Die Wirkungsweise sei wie folgt beschrieben: Befindet sich der Bedienungshebel 10 in der einen, z. B. linken Endstellung, in welcher das Zentralrad 2 abgebremst ist, so wird das andere Zentralrad und damit die getriebene Welle 5 in an sich bekannter Weise schneller angetrieben und die Klauenmuffe 8 in ausgerückter Stellung gehalten. Wird der Bedienungshebel nach rechts gelegt, so wird zunächst die Bremse 3 gelöst, und das Getriebe überträgt über die in Kupplungsstellung gehende Freilaufkupplung 6 im Verhältnis 1:1. Gleichzeitig wird durch Verschieben der Klauenmuffe 8 die Klauenkupplung eingerückt; die Klauen werden aber durch dieThe mode of operation is described as follows: If the operating lever 10 is in the one, e.g. B. left end position in which the central wheel 2 is braked so becomes the other central wheel and thus the driven shaft 5 in a manner known per se driven faster and held the claw sleeve 8 in the disengaged position. Will the If the operating lever is placed to the right, the brake 3 is first released, and the gearbox transmits via the one-way clutch 6 going into clutch position in proportion 1: 1. Simultaneously is by moving the claw sleeve 8 engaged the claw clutch; but the claws are through the
