Die Erfindung betrifft eine Antriebseinheit für Spannvorrichtungen, d.h., insbesondere für sogenannte Schubstangenspanner zur Festlegung von Werkstücken, bestehend aus einem Gehäuse, aus dem eine linear verstellbare, im Gehäuse gelagerte Schubstange aus diesem herausgeführt ist und wobei ferner im Gehäuse im Bereich neben der Schubstangenanordnung ein Antriebsglied angeordnet ist, dessen Abtriebsglied mit dem im Gehäuse befindlichen Ende der Schubstange in Verbindung steht.The invention relates to a drive unit for tensioning devices, that is, especially for so-called push rod tensioners for fixing workpieces, consisting of a Housing from which a linear adjustable, mounted in the housing Push rod is led out of this and further in the Housing in the area next to the push rod assembly a drive member is arranged, the output member with the im Housing located end of the push rod is in communication.

Eine derartige Antriebseinheit ist bspw. nach der DE-A-101 18 319 A1 bekannt. Als Antriebsglied ist hierbei lediglich ein Linearantrieb möglich, dessen Stell- bzw. Kolbenstange ein Querstück für die gelenkige Anbindung einer zweiteiligen Kniehebelkette aufweist, die mit ihrem zweiten Glied am im Gehäuse befindlichen Ende der Schubstange angelenkt ist. Die beiden sich in Folge an das Querstück anschließenden Gelenke der Gliederkette sind dabei in einer Nut geführt, die sich mit einem ersten Teil in Ausschubrichtung erstreckt und dann in ein Bogenstück übergeht, um die Kette in Bezug auf die Schubstange kniehebelartig zur Wirkung zu bringen, wobei in Spannstellung das zweite, mit der Schubstange verbundene Glied dann im Wesentlichen in gleicher Richtung wie die ausgefahrene Schubstange orientiert ist. Die Kraftlinienführung vom Antriebsglied zur Schubstange und umgekehrt ist hierbei relativ ungünstig, und die auftretenden Kräfte müssen über mit Rollen ausgestatteten Gelenke mit Linienberührung via gekurvter Nutwände in das Gehäuse eingeleitet bzw. von diesem aufgenommen werden. Such a drive unit is, for example, according to DE-A-101 18 319 A1 known. As a drive member here is only one Linear drive possible, whose actuator or piston rod a Crosspiece for the articulated connection of a two-part toggle lever chain having, with its second member on in the housing located end of the push rod is articulated. The two in consequence to the crosspiece subsequent joints of the Link chain are guided in a groove, which is with a first part extends in the extension direction and then in a Elbow passes to the chain in relation to the push rod to bring levers to action, with in clamping position the second link connected to the push rod then essentially in the same direction as the extended push rod is oriented. The force line guide from the drive link to push rod and vice versa here is relatively unfavorable and the forces involved must be equipped with rollers Joints with line contact via curved groove walls in the Housing initiated or absorbed by this.

Der Erfindung liegt, ausgehend von einer Antriebseinheit der eingangs genannten Art, die Aufgabe zugrunde, diese dahingehend umzugestalten und zu verbessern, daß die Schubstange sowohl mit linearen als auch drehenden Antriebsgliedern betätigbar ist, wobei in Spannstellung und in beiden Fällen die beiden Kniehebelglieder im Wesentlichen eine Fortsetzung der Schubstangenerstreckung bilden und damit die Spannlast bei verbesserter Kraftlinienführung in linearer Fortetzung der Schubstange in das Gehäuse einleitbar ist.The invention is based on a drive unit of the the type mentioned above, the object of this, to that effect remodel and improve that the push rod with both linear and rotating drive links is actuated, where in clamping position and in both cases, the two toggle links essentially a continuation of the pushrod extension form and thus the clamping load with improved Lines in linear continuation of the push rod in the housing can be introduced.

Diese Aufgabe ist mit einer Antriebseinheit der eingangs genannten Art nach der Erfindung dadurch gelöst, daß die Verbindung zwischen dem Abtriebsglied des Antriebes und dem Ende der Schubstange aus einem Adapter und einem aus drei, durch ein gemeinsames Gelenk verbundenen Gliedern bestehenden Kniehebeltrieb gebildet ist, wobei das freie Ende des ersten Gliedes am Ende der Schubstange, das des zweiten, das Druckglied bildenden Gliedes am Adapter und das des dritten Gliedes in einem Gehäusestützlager angelenkt ist, das im Gehäuse auf der Erstreckungsgeraden der Schubstange angeordnet ist, wobei die Glieder und der Adapter derart einander zugeordnet sind, daß die Glieder in Spannstellung in der Erstreckungsgeraden der Schubstange orientiert sind.
Vorteilhafte Weiterbildungen ergeben sich nach den abhängigern Patentansprüchen.

Um unter Beibehaltung des gleichen Gehäuses 1 und des gleichen Kniehebelsystems 12 den jeweils gewünschten Antrieb 5 und den zugehörigen Adapter 7 herstellerseitg einbauen zu können, ist der Gelenkanschluß 14 für das Druckglied 10 im einen Fall an der Kulisse 7' und im anderen Fall an dem Schneckenradsegment 7", die den jeweiligen Adapter 7 bilden, an sich funktionsentsprechenden Stellen angeordnet, die mit S bzw. S' bezeichnet sind. Für den Hersteller ist also der Vorteil gegeben, wahlweise den einen oder anderen Antrieb 5 mit zugehörigem Adapter 7 bei ansonsten gleichem Gehäuse 1, gleicher Schubstange und gleichem Kniehebelsystem 12 einbauen zu können.To keep the same case 1 and the same Knee lever system 12 the respective desired drive 5 and the to be able to install associated adapter 7 manufacturer side is the joint connection 14 for the pressure member 10 in a case the scenery 7 'and in the other case on the worm wheel segment 7 ", which form the respective adapter 7, functionally equivalent in itself Positions arranged, denoted by S and S ' are. So for the manufacturer, there is the advantage optionally one or the other drive 5 with associated Adapter 7 with otherwise the same housing 1, same push rod and the same toggle lever system 12 to install.

Da bei derartigen Schubstangenspannern auch mit schubstangenseitig einfließenden Torsionsbelastungen gerechnet werden muß, die die ganze Stellmechanik in mehr oder weniger unübersichtlicher Weise zusätzlich belasten würden, besteht eine vorteilhafte Weiterbildung darin, daß die Schubstange 4 aus minestens zwei Stangen 4' gebildet ist, die an ihren äußeren Enden miteinander durch eine Schnittstelle 15 zur Aufnahme unterschiedlicher Druckstücke (nicht dargestellt) verbunden sind, wie dies aus Fig.1 ersichtlich ist.As with such push rod tensioners with push rod side einfließenden torsional loads are calculated must, that the whole Stellmechanik in more or less confusing Way additional burden, there is an advantageous Development in that the push rod 4 off At least two rods 4 'is formed, which at their outer Ends with each other through an interface 15 for receiving different plungers (not shown) connected are, as can be seen from Fig.1.

Die beim Ausführungsbeispiel dargestellten beiden Stangen 4' sind dabei in einer gemeinsamen Stangenführung oder in einzelnen (wie dargestellt) im Durchgriffsbereich in das Gehäuse 1 eingelassenen Stangenführungen 4" geführt.
Auf diese Weise werden also die sonst den normalen und übersichtlichen Kraftlinienverlauf in der Stellmechanik beeinträchtigende Torsionsbelastungen bereits im Durchgriffsbereich von den Stangenführungen 4" aufgenommen.
The two rods 4 'shown in the exemplary embodiment are guided in a common rod guide or in individual rod guides 4 "(as shown) in the passage area in the housing 1.
