Description

Flüssigkeitswechselgetriebe. Die Erfindung betrifft ein Flüssigkeitswechselgetriebe mit umlaufenden Arbeitszylindern, deren Kolben bei jeder Umdrehung zwei Arbeitshübe ausführen. Das Neue besteht darin, da.ß für diese Arbeitszylinder eine besondere Regelungsvorrichtung vorgesehen ist,, derart, daß die Regelung auf beiden Hälften- des Getriebes für je einen Arbeitshub erfolgt. Zu diesem Zweck besteht der exzentrische Führungsring, auf welchem sich die Führungsrollen der Arbeitszylinder bewegen, auszwei gleichartigen Hälften, die gegeneinander gleichmäßig verschoben werden können.Fluid change gear. The invention relates to a fluid change transmission with rotating working cylinders, their pistons two working strokes with each rotation carry out. What is new is that there is a special one for these working cylinders Control device is provided, so that the control on both halves of the transmission takes place for one working stroke each. For this purpose there is the eccentric Guide ring, on which the guide rollers of the working cylinder move, two similar halves that can be evenly shifted against each other.

Auf der Zeichnung ist der eine Teil eines Flüssigkeitsgetriebes in Seitenansicht darge-. stellt.In the drawing, one part of a fluid transmission is in Side view shown. represents.

Der Zylinderblock a trägt in bekannter Weise die mit Führungsrollen b versehenen Kolben, die sich gegen den zweiteiligen Führungsring r1 und r2 legen. Der Führungsring ist derart aus zwei Kreisbogen gebildet, daß während einer Umdrehung des Zylinderblocks jeder Kolben einen doppelten Hub ausführt. Die Verstellung der beiden Teile des Führungsringes r1 und r2 gegeneinander geschieht mit Hilfe der Spindeln t, die Rechts- und Linksgewinde tragen, von dem gemeinsamen Handrad u aus. Beim Drehen der Spindeln t entfernen oder nähern sich die beiden Hälften des Führungsringes. Diese Anordnung hat den Vorteil, daß der Führungsring und die Steuereinrichtung entlastet sind. Die Zu- und Abführung der Druckflüssigkeit erfolgt durch den Mittelzapfen, und zwar durch dessen zwei Steuerflächen s1 und s2, die senkrecht zueinander stehen. Demgemäß sind auch zwei Zuleitungen d und zwei Ableitungen/ vorhanden.The cylinder block a carries in a known manner the pistons provided with guide rollers b, which lie against the two-part guide ring r1 and r2. The guide ring is formed from two circular arcs in such a way that each piston executes a double stroke during one revolution of the cylinder block. The adjustment of the two parts of the guide ring r1 and r2 against each other takes place with the help of the spindles t, which carry right and left-hand threads, from the common handwheel u . As the spindles t rotate, the two halves of the guide ring move away from or approach one another. This arrangement has the advantage that the guide ring and the control device are relieved. The supply and discharge of the hydraulic fluid takes place through the central pin, namely through its two control surfaces s1 and s2, which are perpendicular to each other. Accordingly, there are also two supply lines d and two discharge lines /.
