Description

Gegenstand des Hauptpatentes ist eine hydraulische Antriebsvorrichtung, bei welcher in den Boden eines in einem Druckzylinder angeordneten Kraftkolbens eine Pumpe eingebaut ist, die das hydraulische Druckmittel durch, den Kolben hindurchfördert und damit einen Druckunterschied zwischen den beiden Kolbenseiten erzeugt. Bei dem in dem Patent angegebenen Ausführungsbeispiel ist der Antriebsmotor der Pumpe auf dem Druckzylinder fest gelagert und mit der Pumpe vermittels einer Keilnutenwelle gekuppelt. The subject of the main patent is a hydraulic drive device in which A pump is built into the bottom of a power piston arranged in a pressure cylinder is, which the hydraulic pressure medium through, the piston conveys and thus creates a pressure difference between the two sides of the piston. The in The embodiment specified in the patent is the drive motor of the pump on the The pressure cylinder is fixedly mounted and coupled to the pump by means of a spline shaft.

Die Erfindung erstrebt eine bauliche Vereinfachung einer derartigen Vorrichtung und erreicht diese dadurch, daß außer der Pumpe auch der Antriebsmotor mit dem Kraftkolben zusammengebaut ist. Auf diese Weise kann eine komplizierte Kupplungseinrichtung, wie sie die Keilnutenwelle darstellt, in Fortfall kommen. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.The invention aims at a structural simplification of such a device and this is achieved by the fact that, in addition to the pump, the drive motor with the power piston is assembled. In this way, a complicated coupling device, such as it represents the spline shaft, come in omission. An embodiment of the invention is shown in the drawing.

Es bezeichnen 1 den feststehenden Druckzylinder und 2 den in diesem angebrachten Kraftkolben. Der Kolben ist als Hohlzylinder ausgebildet, auf dessen oberer Stirnfläche der Antriebsmotor 3 gelagert ist, während in seinen Boden die vermittels der Welle 4 mit dem Motor gekuppelte Kreiselpumpe 5 eingebaut ist. Der Kolben trägt an seinem oberen Ende außerdem zwei Stangen 6, welche vermittels eines ,Querhauptes 7 fest verbunden sind. Zwischen dem Querhaupt 7 und dem Druckzylinder 1 sind Spiral· federn 8 angebracht, welche die Rückgangsbewegung des Kolbens in seine Normallage unterstützen. Die Öse 9 des ,Querhauptes. 7. dient zur Kupplung des Kolbens mit der Arbeitsvorrichtung·. It denotes 1 the fixed pressure cylinder and 2 the one attached in this Power piston. The piston is designed as a hollow cylinder, on the upper end face of the Drive motor 3 is mounted, while in its bottom the means of the shaft 4 with the motor coupled centrifugal pump 5 is installed. The piston also has two rods 6 at its upper end, which are firmly connected by means of a crosshead 7. Between the crosshead 7 and the pressure cylinder 1 are attached spiral springs 8, which the return movement of the piston into its normal position support. The eyelet 9 of the, crosshead. 7. is used to couple the piston with the working device ·.

Die Arbeitsweise der Vorrichtung ist wie folgt:The operation of the device is as follows:

Sobald die Kreiselpumpe angetrieben wird, wird das hydraulische Druckmittel aus dem Innern des Kraftkolbens 2 in den Druckzylinder ι hineingedrückt. Dadurch wird entsprechend dem durch die Kreiselpumpe erzeugten Druckunterschied 'ein Druck auf den Kolben 2 ausgeübt, so daß sich dieser nach oben bewegt und unter Vermittlung der Öse 9 die gewünschte Arbeitsbewegung ausführt. Wird der Motor 3 ausgeschaltet, so findet sogleich ein Druckausgleich zwischen dem Innern des Arbeitskolbens 2 und dem Druckzylinder ι statt. Der Kolben sinkt nun infolge seines Eigengewichtes, des Gewichtes des Motors und der Pumpe in den Zylinder zurück, wobei die Rückzugfedern 8 diese Bewegung unterstützen.As soon as the centrifugal pump is driven, the hydraulic pressure medium is released from the Inside the power piston 2 pressed into the pressure cylinder ι. This will accordingly the pressure difference generated by the centrifugal pump 'a pressure on the Piston 2 exercised so that it moves upwards and with the intermediary of the eyelet 9 performs the desired work movement. If the motor 3 is switched off, then takes place immediately a pressure equalization between the interior of the working piston 2 and the pressure cylinder ι instead. The piston now sinks due to its own weight, the weight of the motor and the pump back into the cylinder, the return springs 8 this movement support.

Die Erfindung kann in der gleichen Weise wie die Antriebsvorrichtung nach dem Hauptpatent für die verschiedensten Zwecke, z. B. für Bremsen, Kupplungen, Tür- und Fensterschließvorrichtungen, Schweißanordnungen, Pumpen u. dgl., verwendet werden.The invention can in the same way as the drive device according to Main patent for various purposes, e.g. B. for brakes, clutches, door and Window closers, welding assemblies, pumps and the like can be used.
