null aus~z\vci Reibungskupplungen und einem Umlauf räderwerk zusammensetzt, in solcher Anordnung, daß die getriebene Welle derart mit einer stetig umlaufenden treibenden Welle verbunden werden kann, daß sie in derselben Richtung mit derselben Geschwindigkeit oder in demselben Sinne mit verminderter Geschwindigkeit, oder in umgekehrter Richtung mit einer genau beschränkten oder noch geringeren Geschwindigkeit als der letzteren umlaufen oder endlich von der Hauptwelle getrennt und stillgesetzt werden kann. Tn jedem Falle kann die Geschwindigkeit der getriebenen Welle allmählich vom Stillstand bis zu der gewünschten Geschwindigkeit gesteigert und .alle Wechsel können ohne Anhalten der Hauptantriebwelle bewirkt werden.zero from ~ z \ vci friction clutches and one Revolving gears composed in such an arrangement that the driven shaft such can be connected to a continuously rotating driving shaft that they are in the same Direction at the same speed or, in the same sense, at reduced speed, or in the opposite direction with a precisely limited or even less speed than the latter revolve or can finally be separated from the main shaft and stopped. Tn In any case, the speed of the driven shaft can gradually from a standstill increased to the desired speed and all changes can be made without stopping the main drive shaft.

Zu diesem Zwecke werden die Reibkupplungen und das Umlaufräderwcrk derart zu- ; sainniengcstellt, daß immer, wenn die eine Kupplung eingerückt wird, die andere außer Kingriff bleibt; die eine' Kupplung verbindet die beiden Wellen miteinander und das Umlauf räderwerk dreht sich als ein Ganzes, während, wenn die andere Kupplung eingerückt ist, diese das Zwischengetriebe festhält und eine Umsteuerung der getriebenen Welle stattfindet; jede der beiden Kupplungen kann man unter der Belastung gleiten lassen und dadurch die zu derjenigen der treibenden Welle gleich oder entgegengesetzt gerichtete Uinlaufbcwcgung der getriebenen Welle innerhalb gewisser Grenzen beliebig ändern.For this purpose, the friction clutches and the Umlaufräderwcrk are used in such a way. ; sainniengcetzt that always when the one Clutch is engaged, the other one remains out of Kingriff; which connects a 'coupling the two shafts with each other and the gear train rotates as a whole, while, when the other clutch is engaged, it holds the intermediate gear in place and a reversal of the driven shaft takes place; each of the two couplings one can slide under the load and thereby become that of the driving force Shaft in the same or opposite direction Uinlaufbcwcgung the driven shaft within change at will within certain limits.

Das in Fig. 1 veranschaulichte Getriebe zeigt zwei Kupplungen Q und R und ein dazwischengeschaltetes Umlaufräderwerk. Die erstcrcn bilden nicht den Gegenstand der vorliegenden Erfindung. Jede Kupplung'besteht aus zwei Sätzen (A und B) von Lamellen, deren ineinander greifende Teile C (Fig. 7, 8 und 9) gleichförmig gewellt sind; die beiden Lamellensätze sind entsprechend mit den zu kuppelnden Teilen verbunden, nämlich die Scheiben A durch die Zähne α und die Scheiben B durch die Zähne b. Die wechselweise aufeinander folgenden Lamellen werden in der Regel durch an ihnen befestigte Federn d (Fig. S und <)) außer Berührung gehalten, so daß die Kupplung frei läuft. Zwecks Eingriffs werden die Lamellen durch eine die Spannung der Federn J überwindende Kraft zusammengedrückt, die ebenfalls durch Federn ausgeübt wird. welche bestrebt sind, die Lamellen aneinander zu drücken, die aber zurückgehalten werden, wenn die Kupplung leer laufen soll.The transmission illustrated in FIG. 1 shows two clutches Q and R and an interposed planetary gear train. The former do not form the subject of the present invention. Each clutch consists of two sets (A and B) of lamellas, the interlocking parts C (Figs. 7, 8 and 9) of which are uniformly corrugated; the two sets of plates are correspondingly connected to the parts to be coupled, namely the disks A by the teeth α and the disks B by the teeth b. The alternately successive lamellae are usually kept out of contact by springs d (Fig. S and <)) attached to them, so that the clutch runs freely. For the purpose of engagement, the lamellas are compressed by a force overcoming the tension of the springs J , which force is also exerted by springs. which strive to press the slats against each other, but which are held back when the clutch is to run idle.

Claims

The pressure of these springs can be regulated in such a way that it is sufficient to bring about an engagement without sliding, or else to bring about an engagement which allows a certain sliding. The lamellae are immersed in a lubricating fluid that absorbs the heat that is produced, with which a housing enclosing the gear mechanism is filled and which flows through holes c in the lamellae. The inner and outer parts of the lamellas are flat and form flanges D, which serve to stiffen the lamellas against twisting and to promote the radiation of heat.

The housing G and the disks B of the coupling Q are stationary, while the sleeve E and the disks Λ of this coupling can rotate against the shaft .S '. The housing G ¹ and the disks 1 { ^[of the coupling R are fastened to the shaft T by means of bolts 8, the sleeve E ¹ and the disks A ^{] of} this coupling, on the other hand, are attached to the shaft S : therefore, if the disks .1 'and IV of the clutch R in engagement with each other and those of the clutch Q are free, the two shafts are directly connected and rotate in the same direction at the same speed if there is no sliding, or at different speeds if sliding is allowed.

An internally toothed wheel Z is attached to the housing G ^{1 of} the clutch R and thus to the shaft T , and an externally toothed wheel S is keyed onto the shaft S; .v in these two gears and t is engaged by a number of planetary gears V (Fig. 2), so that on a flange of the sleeve /: the clutch · Q ge-'lagert 'are such that they can rotate about their axes. When the disks / 1 and B of the clutch Q are engaged and those of the clutch R are free, the gearwheel / rotates with the shaft 7 ″, and since the intermediate gear carrier is now locked, the planetary gears V rotate about their own axes and rotate the wheel λ and the shaft S in the direction opposite to the direction of rotation of the shaft T.

In order to give the intermediate wheels V as firm a hold as possible, they are made from one piece with their pivot pins, and the latter are mounted on the one hand in the flange of the inner sleeve E of the coupling Q and on the other hand in a ring ν , which by means of bolts of a number of projections q of the socket flange is held (Fig. 1 and fi).

The springs .V (Fig. Ι) are in recesses of a ring j on from the

Io ^¹ Io ^ ¹

If G and G 'of both couplings are borne bolts o, are tightened by the nuts sitting on these bolts and press the ring 2 against the coupling. Bolts r inserted into the ring 2 transmit this thrust to the plate Λ / and the lamellae A B. The arrangement just explained is only shown in the section of the coupling R , but it is equipped with it in each of the couplings.

The pressure of the springs .V is canceled by a fork lever 3, which moves the ring 4 through the pin 5; on the ring q 2 rotatably attached pushers ο serve to hold the multi-plate clutch in the disengaged position (Fig. 5). These pushers <> are urged into the position indicated in FIG. 5 by small springs 7 when the ring - is withdrawn by the fork lever 3. In this position they support themselves with a pin against part G and keep the bolts r away from the plates Λ /. If, on the other hand, the lever 3 is moved to the other position for the purpose of engaging the clutch, the pusher (1 is rotated about its pivot pin by the ring 4 against the pressure of the springs 7, so that the bolts attached to them penetrate the holes in the frame G. The pushers O are also present on both clutches if they are only shown in the section of the clutch O.
