Description

Flüssigkeitswechselgetriebe. Die Erfindung bietet eine Neuerung an Flüssigkeitswechselgetrieben mit sternförmig angeordneten Kolbenpumpen, deren Antrieb durch ein gemeinsames Exzenter erfolgt, dessen Hub durch einen es durchsetzenden, längsverschiebbaren schiefen Zylinder verändert werden kann.Fluid change gear. The invention offers an innovation Fluid change gears with piston pumps arranged in a star shape, their drive takes place by a common eccentric, the stroke of which is carried out by an enforcing, longitudinally displaceable inclined cylinder can be changed.

Bei den bisher bekannten Flüssigkeitswechsel- I getrieben dieser Art erfolgte die Kupplung des Exzenters mit der Antriebwelle durch Vermittlung des schiefen Zylinders. Dabei mußten die infolge der Neigung des schiefen Zylinders durch . die Wirkung der Kolbenstangen auftretenden achsialen Schubkräfte, welche eine Verstellung ' des Exzenters zum Zylinder erstreben, dadurch , aufgehoben werden, daß das Exzenter gegen achsiales Verschieben durch ortsfeste Anschläge festgehalten wurde. Die dadurch entstehenden Reibungsverluste zehrten jedoch einen erheblichen Teil'der Arbeitsleistung auf.In the previously known fluid change drives of this type the coupling of the eccentric with the drive shaft was carried out by arranging the crooked Cylinder. They had to go through because of the inclination of the crooked cylinder. the Effect of the piston rods occurring axial thrust, which an adjustment 'Strive of the eccentric to the cylinder, thereby, to be canceled that the eccentric was held against axial displacement by stationary stops. The thereby The resulting frictional losses, however, consumed a considerable part of the work performance on.

Gemäß der Erfindung werden diese arbeit- . verzehrenden ortsfesten Anschläge, überflüssig, indem die Kupplung des Exzenters mit der Antriebwelle nicht mehr durch Vermittlung des schiefen Zylinders, sondern unmittelbar durch einen Keil erfolgt, der den schiefen Zylinder in einem dessen Längsverschiebungen zulassenden Längsschlitz und die Antriebwelle spielfrei durchsetzt und dessen Enden in einander gegenüberliegende Aussparungen des Exzenters eingreifen, wodurch der Keil auch die achsialen Schubkräfte aufnimmt. In den Zeichnungen ist eine Ausführungsform des Erfindungsgegenstandes dargestellt, und zwar zeigt Fig. i einen' senkrechten Längsschnitt durch eine Pumpe mit dem Antrieb, während Fig. 2 ein Querschnitt durch das Exzenter für sich und Fig. 3 eine Rückansicht des Exzenters ist. Fig. 4. schließlich zeigt einen Grundriß. des schiefen Zylinders.According to the invention, these are work-. consuming stationary Stops, superfluous by not coupling the eccentric to the drive shaft more through the mediation of the oblique cylinder, but directly through a wedge takes place, which allows the oblique cylinder in one of its longitudinal displacements Longitudinal slot and the drive shaft penetrated backlash-free and its ends into one another engage opposite recesses of the eccentric, whereby the wedge also the absorbs axial shear forces. In the drawings, an embodiment of the Subject of the invention shown, namely Fig. I shows a 'vertical longitudinal section by a pump with the drive, while Fig. 2 shows a cross section through the eccentric and Fig. 3 is a rear view of the eccentric. Fig. 4 finally shows a floor plan. of the crooked cylinder.

Die Kolbenstange des im Pumpenzylinder i beweglichen Kolbens 3 umfaßt mit dem Exzenterringe die Exzenterscheibe 4, in und zu welcher der schiefe Zylinder 5 beispielsweise durch den Stellhebel 6 auf der ihn durchsetzenden Welle 2 verschoben werden kann. Die Verbindung der Antriebwelle 2 mit der Exzenterscheibe 4 erfolgt gemäß der Erfindung durch einen die Welle 2 senkrecht zur Achse und spielfrei in einem Loche 7' durchsetzenden Keil 7, dessen Enden in entsprechende Aussparungen der Exzenterscheibe 4 eingreifen und für den der schiefe Zylinder einen Längsschlitz 8 aufweist, der wohl die erforderlichen Verschiebungen des Zylinders 5 auf der Welle 2, aber keine Verdrehungen zu ihr zuläßt. Die durch den Keil 7 bewirkte feste Verbindung der Exzenterscheibe 4 mit der Antriebwelle 2 hebt jede Wirkung seitlicher Schubkräfte auf den schrägen Zylinder 5 auf. Unbeabsichtigte Verstellungen werden demnach vermieden, ohne das irgendwelche Reibungsverluste durch das die Stellung sichernde Mittel auftreten.The piston rod of the piston 3 movable in the pump cylinder i, with the eccentric ring, encompasses the eccentric disk 4, in and to which the inclined cylinder 5 can be displaced, for example by the adjusting lever 6 on the shaft 2 penetrating it. According to the invention, the drive shaft 2 is connected to the eccentric disk 4 by a wedge 7 which penetrates the shaft 2 perpendicular to the axis and free of play in a hole 7 ', the ends of which engage in corresponding recesses in the eccentric disk 4 and for which the inclined cylinder has a longitudinal slot 8 has, which probably allows the necessary displacements of the cylinder 5 on the shaft 2, but no rotations to it. The fixed connection of the eccentric disk 4 to the drive shaft 2 caused by the wedge 7 cancels any effect of lateral thrust forces on the inclined cylinder 5. Unintentional adjustments are therefore avoided without any frictional losses occurring due to the means securing the position.
