Gegenstand der Erfindung ist eine Lagerung für die Leit- und Spannrolle von Geschwindigkeitswechselgetrieben mit Kettenumschaltung, bei welcher bei Aufliegen der Kette auf einem kleinen Zahnrad eine hinreichende Umschlingung desselben bei entsprechender Umschlingung der Leitrolle und der Spannrolle erzielt wird, während bei Aufliegen der Kette auf einem großen Zahnrad die richtige Umschlingung desselben nur mit geringerer Umschlingung der Spannrolle und praktisch ohne Umschlingung der Leitrolle erreicht wird.The subject of the invention is a bearing for the guide and tensioning pulley of speed change transmissions with chain switching, in which when the chain rests on a small toothed wheel, a sufficient looping of the same with the appropriate Wrapping of the guide pulley and the tension pulley is achieved while resting on the Chain on a large cogwheel the correct looping of the same only with a smaller looping the tension pulley and practically without wrapping around the guide pulley.

Hierfür enthält die erfindungsgemäße Vorrichtung eine in möglichster Nähe der Freilaufnabe liegende feste Tragachse, welche einen Haltearm trägt, dessen Stellung durch Blockierung mittels einer Mutter od. dgl. festgelegt oder mittels eines Regelsystems, z. B. mit Zugstange oder Seil, entsprechend den Betriebsbedingungen verändert werden kann, wobei der Haltearm die Schaltachse trägt, deren Entfernung von der Tragachse festliegt oder z. B. mittels einer Gleitbahn regelbar ist, und welche eine Leitrolle sowie einen schwenkbaren, unter Federdruck stehenden, die Spannrolle tragenden Arm trägt.For this purpose, the device according to the invention contains a hub which is as close as possible to the freewheeling hub fixed support shaft, which carries a holding arm, whose position is blocked by means of a nut Od. Like. Fixed or by means of a control system, z. B. with tie rod or rope, according to the operating conditions can be changed, with the holding arm carrying the switching axis, its distance is fixed by the support axis or z. B. can be regulated by means of a slide, and which is a guide roller and a pivotable, spring-loaded arm carrying the tensioner pulley.

Die Erfindung ist unter Bezugnahme auf die Zeichnung beispielshalber erläutert.The invention is explained by way of example with reference to the drawing.

Abb. 1 zeigt eine erfindungsgemäße Lagerung bei Aufliegen der Kette auf dem größten Zähnrad;Fig. 1 shows a storage according to the invention with the chain resting on the largest gear wheel;

Abb. 2 zeigt die gleiche Lagerung bei Aufliegen der Kette auf dem kleinsten Zahnrad;Fig. 2 shows the same bearing with the chain resting on the smallest gear wheel;

Abb. 3 zeigt eine mögliche Stellung des Haltearmes der Lagerung gemäß Abb. 1 und 2 zur Erzielung einer größeren Umschlingung des kleinsten Zahnrades.Fig. 3 shows a possible position of the holding arm of the storage according to Fig. 1 and 2 to achieve this a larger wrap around the smallest gear.

Bei dem in Abb. 1 und 2 dargestellten Ausführungsbeispiel weist die Vorrichtung eine Tragachse 1 auf, an welcher ein Haltearm 2 schwenkbar ist, der mit einer Mutter 3 für seine Feststellung in der gewünschten Stellung versehen ist. Für diese Befestigung kann auch ein beliebiges anderes Steuersystem mit Stange oder Seil mit einer Gegenfeder benutzt werden, wobei die Neigung des Armes 2 gegenüber der durch die Nabenachse 4 gehenden Lotrechten die zu erhaltende Regelung darstellt. Wenn die Mutter 3 zur Blockierung dient, wird diese Regelung bei Stillstand des Fahrzeuges vorgenommen, während, wenn die Mutter 3 durch ein Gelenk ersetzt ist, die Neigung während des Betriebes durch ein Seil, eine Stange oder ein beliebiges anderes Mittel verändert werden kann. Der Arm 2 trägt bei dem dargestellten Ausführungsbeispiel die Schaltachse 5, wobei jedoch auch eine beliebige anders ausgebildete Schaltvorrichtung an dem Arm 2 angebracht sein kann. Der Abstand zwischen den Achsen 1 und 5 kann konstant sein und durch die Abmessungen der Zahnräder der benutzten Lagerung für die Leit- und SpannrolleIn the exemplary embodiment shown in FIGS. 1 and 2, the device has a support axis 1 on, on which a support arm 2 is pivotable, with a nut 3 for its determination in the desired Position is provided. Any other control system can be used for this attachment be used with a rod or rope with a counter spring, the inclination of the arm 2 opposite the perpendicular passing through the hub axis 4 represents the regulation to be obtained. When the mother 3 is used for blocking, this control is carried out when the vehicle is stationary, while if the nut 3 is replaced by a joint, the inclination during operation by a rope, a rod or any other means can be changed. The arm 2 carries in the illustrated embodiment the switching axis 5, but also any other switching device can be attached to the arm 2. The distance between axes 1 and 5 can be constant and by the dimensions of the gears of the bearing used for the guide and tension pulley

Kettengangschaltung bestimmt werden oder kann mittels der Gleitbahn 6 regelbar sein, um die Umschaltvorrichtung entsprechend dem Durchmesser der Zahnräder der benutzten Gangschaltung diesen nähern oder entfernen zu können. Diese Regelungsart stellt keine Einschränkung dar, sondern es kann auch jede andere bekannte Vorrichtung zur Veränderung des Abstandes zwischen den Achsen 1 und 5 benutzt werden.Chain gear shifting can be determined or can be regulated by means of the slide 6 to the switching device Approach it according to the diameter of the gears of the gear shift used or remove it. This type of regulation does not represent a restriction, but any one can also do so Another known device for changing the distance between the axes 1 and 5 is used will.

Die Schaltachse 5 trägt die Leitrolle 7 und zwei die Spannrolle 10 haltende Flansche 8 und 9. Eine Feder 11 bewirkt die Spannung der Kette 12. Es ist selbstverständlich, daß eine beliebige andere Form des Spannarmes sowie Rollen, Zahnräder mit oder ohne Flansche, andere Formen der Kettenführung, auf Zug, Druck oder Verdrehung arbeitende Spannfedern usw. für diese Regelvorrichtung im Rahmen der Erfindung verwendet werden können.The switching axis 5 carries the guide pulley 7 and two flanges 8 and 9 holding the tension pulley 10. A spring 11 acts to tension the chain 12. It goes without saying that any other form of the Tension arm as well as rollers, gears with or without flanges, other forms of chain guidance, on train, Pressure or torsion working tension springs etc. for this control device within the scope of the invention can be used.

Abb. 1 zeigt die Verwendung der großen Verzahnungen der Kettengangschaltung, wobei nur die Spannrolle 10 mit der Kette 12 in Berührung steht.Fig. 1 shows the use of the large teeth of the chain gear shift, with only the The tension roller 10 is in contact with the chain 12.

Abb. 2 zeigt die Verwendung der kleinen Zahnräder, wobei die Berührung zwischen der Kette 12 und der Leitrolle 7 eine richtige Umschlingung des betreffenden Zahnrades 13 gewährleistet.Fig. 2 shows the use of the small gears, with the contact between the chain 12 and the guide roller 7 ensures that the relevant gear 13 is wrapped around correctly.

Abb. 3 zeigt eine Verstellung des Armes 2 nach vorn zur Erzielung einer noch größeren Umschlingung, wenn eine solche erforderlich ist.Fig. 3 shows an adjustment of the arm 2 forwards to achieve an even greater wrap, if this is necessary.

In Abb. 2 ist noch beispielshalber das Seil 15 dargestellt, welches gemäß einem bekannten System die Aufhebung des Druckes der Spannrolle 10 auf die Kette 12 gestattet; es ist jedoch selbstverständlich,In Fig. 2, the rope 15 is shown by way of example, which according to a known system Relief of the pressure of the tension roller 10 on the chain 12 allowed; however, it goes without saying
