Gegenstand der Erfindung ist eine Vorrichtung zur selbsttätigen Aufrechterhaltung der Kupplung, zum Entkuppeln und zum Bremsen an Reibräderwechselgetrieben, namentlich solchen mit achsial zueinander gelagertem treibenden und getriebenen Rad, derart, daß das angetriebene Rad einerseits unter denn entkuppelnden Druck einer Feder und anderseits unter dem stärkeren Kupplungsdruck eirar Lagerbüchse der Getriebeachse steht, die beispielsweise mittels Schraubengewindes ächsial verschiebbar gelagert ist und vermittels eines federbelasteten. Fußhebels in die Kupplungsstellung vorgeschoben wird, während beim Entkuppeln des Rreibrädergetriebes oder im Gefolge desselben ein mit dem getriebenen Rad oder dessen Zahnräderv orgelege verbundener Bremskegel durch die Entkupplungsfeder mit einem ortsfesten Hohlkegel in Eingriff gebracht wird.Coupling, uncoupling and braking device on friction wheel change transmissions. The invention relates to a device for automatic maintenance the clutch, for decoupling and for braking on friction wheel change gears, namely those with axially mounted driving and driven wheels, such as that the driven wheel on the one hand under the uncoupling pressure of a spring and on the other hand, under the stronger clutch pressure eirar bearing bush of the transmission axis stands, which is mounted axially displaceably, for example by means of screw thread is and by means of a spring-loaded. The foot lever to the clutch position is, while disconnecting the Rreibrädergetriebes or in the wake of the same a brake cone connected to the driven wheel or its gear drive brought into engagement by the decoupling spring with a stationary hollow cone will.

Zweck der Erfindung ist, bei Reibräderwechselgetrieben den Reibungsdruck unnachgiebig zu gestalten und selbsttätig aufrechtzuerhalten, eine Entkupplung zwangläufig ermöglichen zu können und im Gefolge derselben nötigenfalls eine Bremsung des infolge Fliehkraft weiterrollenden Teiles des Getriebes und der getriebenen Welle oder Arbeitswelle bewirken zu können beim Umlauf derselben in beiden Richtungen.The purpose of the invention is to reduce the friction pressure in friction gear change transmissions To shape relentlessly and to maintain automatically, a decoupling inevitably to enable and in the wake of the same, if necessary, a braking of the result Centrifugal force rolling part of the gearbox and the driven shaft or working shaft to be able to cause the same in both directions when circulating.

Eine Ausführungsform des Gegenstandes der Erfindung ist in der Zeichnung in Verbindung mit einem Reibräderwechsel- und -wendegetriebe, zum Teil. im Schnitt, dargestellt.An embodiment of the subject matter of the invention is shown in the drawing in connection with a friction wheel change and reversing gear, in part. on average, shown.

Auf der Antriebswelle i ist das Reibrad 2 befestigt und der ortsfeste Lagerrahmen 3 für die Übertragungsräder q. und 5 sowie das drehbare Abnahmerad 6 gelagert. Das an dem Rad 6 sitzende Kegelrad 7 steht mittels der Planetenräder 8 und 9 mit dem mit der Antriebswelle i umlaufenden, auf ihrem Keil ii achsial verschiebbaren Kegelrad io in Verbindung. Der Spurzapfen 12c der anzutreibenden Welle 12, der in seiner Längsbohrung der Antriebswelle i ein zweites Lager bietet, ist in seinem glockenartigen Ansatz i 2a als Träger der Planetenräder 8 und 9 ausgebildet und läuft in der mit Außengewinde versehenen, in dem Auge des Lagerbocks 14 schraubend verstellbaren Lagerbuchse 13 um. Der Druck der Buchse 13 wird durch das Drucklager 15 auf den Spurzapfen 12C und von diesem über die Nabe des Kegelrades io auf das Reibrädergetriebe 2, 3, ¢, 5, 6 übertragen und von dem Drucklager 16 der Antriebswelle i aufgenommen. Dem Bremskegel 12b des Spurzapfens 12c der Arbeitswelle 12 gegenüber ist an dem Lagerbock 14. ein Bremsring 17 angeordnet. Durch die Feder 18 wird mittels des am Lagerbock i ¢ gelagerten, zweckmäßig als Fußtritt ,Ausgebildeten Winkelhebels i 9 die mit selbs_.@perrendem Linksgewinde verseherye Lagerbuchse 13 aus dem Lagerbock i¢ herausgeschraubt, wobei die Bremsglieder 12b und i7 gelöst, der Reibungsdruck in dem Reibrädergetriebe aufrechterhalten und bei Abnutzung ergänzt wird. Beim Schwingen des Winkelhebels i9 entgegen dem Zug der Feder 18 wird die Lagerbuchse 13, den Reibungsdruck aufhebend, unter Mitnahme des Spurzapfens mittels des Stellringes 20 zurück in den Lagerbock i¢ geschraubt, welcher Bewegung alle Teile von 3 bis io unter dem Druck der Feder 21 folgen und eine Entkupplung der Übertragungsräder q. und 5 von der Antriebsscheibe 2, die zugleich Schwungrad eines Motors sein kann, bewirkt. Bei weiterem Zurückschrauben der Lagerbuchsd 13 mittels des Fußhebels i 9 tritt die Bremsvorrichtung 12b, 17 in Tätigkeit, die Arbeitswelle und somit das ausrollende Fahrzeug, die Arbeitsmaschine o. dgl. bremsend; wobei der sinngemäße Umlauf der Reibräder und des Umlaufrädergetriebes aufrechterhalten wird.The friction wheel 2 and the stationary one is attached to the drive shaft i Bearing frame 3 for the transmission wheels q. and 5 as well as the rotatable removal wheel 6 stored. The bevel gear 7 seated on the wheel 6 stands by means of the planetary gears 8 and 9 with the one rotating with the drive shaft i and axially displaceable on its wedge ii Bevel gear OK in connection. The track pin 12c of the shaft 12 to be driven, which is shown in its longitudinal bore of the drive shaft i offers a second bearing is in its bell-like approach i 2a as a carrier for planet gears 8 and 9 educated and runs in the externally threaded, screwing into the eye of the bracket 14 adjustable bearing bush 13 to. The pressure of the bush 13 is through the thrust bearing 15 on the track pin 12C and from this via the hub of the bevel gear io to the Friction gears 2, 3, ¢, 5, 6 transferred and from the thrust bearing 16 of the drive shaft i added. The brake cone 12b of the track pin 12c of the output shaft 12 opposite a brake ring 17 is arranged on the bearing block 14. By the spring 18 is means of the angle lever, which is supported on the bearing block i ¢ and is expediently designed as a footstep i 9 the bearing bush 13 from the bearing block provided with self-locking left-hand thread i ¢ unscrewed, with the brake members 12b and i7 released, the frictional pressure is maintained in the friction gear and supplemented when worn. When swinging of the angle lever i9 against the train of the spring 18, the bearing bush 13, the frictional pressure lifting, taking the track pin by means of the adjusting ring 20 back into the Bearing block i ¢ screwed, which movement all parts from 3 to io under the pressure follow the spring 21 and a decoupling of the transmission wheels q. and 5 of the Drive pulley 2, which can also be the flywheel of an engine, causes. at further screwing back the Lagerbuchsd 13 by means of the foot lever i 9 occurs Braking device 12b, 17 in action, the working shaft and thus the rolling one Vehicle braking the work machine or the like; whereby the analogous circulation of the Friction wheels and the epicyclic gear is maintained.
