Description

Stufenloses Reibräderwechselgetriebe mit auf der An- und Abtriebswelle verschiebbaren Reibräderpaaren Die vorliegende Erfindung ist eine Weiterbildung der Bauform von Reibräder'wechselgetrieben nach Patent 721 635. Infinitely variable friction wheel change transmission with friction wheel pairs displaceable on the input and output shaft The present invention is a further development of the design of friction wheel change transmissions according to patent 721 635.

Bei dieser bekannten Bauform liegt der von Hand aus verstellbare Mitnehmerreibring zwischen ihn innen und außen erfassenden Rollen, die in einem senkrecht zu den .Getriebewellen verstellbaren Gabelträger drehbar gelagert- sind. Dabei sind mindestens drei Rollen erforderlich., so daß sich eine Dreieckabstützung des Mitnefimerreibrings ergibt, die seine Selbsteinstellung'erschwert.In this known design, the driver friction ring, which can be adjusted by hand, is located between it inside and outside grasping roles, which in a perpendicular to the .Getriebewellen adjustable fork carriage are rotatably mounted. There are at least three roles required., so that there is a triangular support of the Mitnefimer friction ring, which makes his self-attitude difficult.

Demgegenüber kennzeichnet sich die Erfindung dadurch, daß die Abstützung des Mitnehmerreiibrings nur einachsig erfolgt, d. h. daß sämtliche Ab-stützrollen in einer einzigen, Achse liegen, wozu im Ring Nuten ausgebildet sind, in welche die mittels des Trägers verstellbaren Rollen eingreifen. Dadurch, daß nur noch zwei in gleicher Achse liegende Rollen oder nur noch eine Rolle den Mitnehmerring abstützen, wird die Reibung vermindert und der Kraftaufwand geringer. Der kurze, den Mitnehrner reibring nicht mehr umfassende Rollenträger ergibt eine vereinfachte Bauform und erleichtert den Zusammenbau des Getriebes. Zudem stellt sich der Mitnehmerreibring auch leichter von selbst in die zur Kraftübertragung erforderliche Lage ein als bei drei und mehr Rallen.In contrast, the invention is characterized in that the support of the driver ring only takes place uniaxially, d. H. that all support rollers lie in a single axis, for which purpose grooves are formed in the ring, in which engage the adjustable rollers by means of the carrier. Because only two Rollers lying in the same axis or only one roller support the driver ring, the friction is reduced and the effort required less. The short one, the Mitnehrner Friction ring no longer comprehensive roller carrier results in a simplified design and facilitates the assembly of the gearbox. In addition, the driver friction ring arises also more easily by itself into the position required for power transmission than with three or more rails.

Die Zeichnung zeigt in Abb. r den Mitnehmerreibring in Vorderansicht; Abb. 2 ist ein Höhenschnitt nach der Linie A-13 in Abb. t, und Abb. 3 zeigt im Querschnitt eine andere Ausführungsform des Mi.tnehmerref)rings.The drawing shows in Fig. R the driver friction ring in a front view; Fig. 2 is a vertical section along the line A-13 in Fig. T, and Fig. 3 shows in cross section Another embodiment of the Mi.tnehmerref) ring.

5 ° ist die Abtriebswelle mit dem kegelscheibenförmigen Reibräderpaar C, 7, und S ist die Antriebswelle finit dein anderen Reibräderpaar 9, io. Der zwischen den Reibräderpaaren befindliche Mitnebmerreibring id ist erfindungsgemäß als Nutenring ausgestaltet. Bei der Ausführungsform nach den Abb. i und 2 hat der Mitnebmerreibring id beiderseits gleichgeformte Ringnuten 26, in welchen oben die Rollen 24 gleichachsig eingebettet sind, die im gabelartigen Träger 23 lagern. Dieser sitzt am Bolzen -22, der als Zahnstange ausgebildet ist und mittels des Ritz-els :..>o durch das Handrad i9 senkrecht verstellt werden kann.5 ° is the output shaft with the conical disk-shaped friction wheel pair C, 7, and S is the drive shaft finite your other pair of friction wheels 9, ok The Mitnebmerreibring id located between the friction wheel pairs is according to the invention designed as a grooved ring. In the embodiment according to Figs. I and 2 has the Mitnebmerreibring id on both sides identically shaped annular grooves 26 in which the top Rollers 24 are coaxially embedded, which are stored in the fork-like carrier 23. This sits on the bolt -22, which is designed as a rack and by means of the Ritz-els : ..> o can be adjusted vertically with the handwheel i9.

Je nach der 'Höheneinstellung des Mitnebnierreibrings greift dieser unterschiedlich an den Reibräderpaaren an, wodurch die Geschwindigkeit der Abtriebswelle j geändert und geregelt wird.Depending on the height setting of the Mitnierreibring this engages differently on the friction wheel pairs, whereby the speed of the output shaft j is changed and regulated.

Bei der Ausführungsform nach Abh.2 ist der Mitnehinerreibring 14 nur auf der einen Seite mit einer Nut -26 verseben, so daß liier auch nur mehr eine Rolle a4 erforderlich ist, die im vinschenkeligen Träger23 ihr Lager bat.In the embodiment according to Abh.2 the driver friction ring 14 is only on one side with a groove -26, so that there is only one Roll a4 is required, which asked for its storage in the vinschenkeligen carrier23.
