Description

  

      Elektrohydraulisches    Aggregat zur Erzeugung     linearer        Kraftbewegungen       Für die Betätigung der     ferngesteuerten    Klappen,  Schieber und sonstigen Einrichtungen in Fabrikanla  gen wurden bisher Elektromotoren mit übertragungs  getrieben oder     hydro-    oder pneumatische Einrichtun  gen mit langen Rohrleitungen gebraucht. Wegen ihrer  hohen Anschaffungspreise wurden diese Steuerungen  nur selten in den Fabrikanlagen installiert.  



  Der Erfindungsgegenstand ist ein elektrohydrauli  sches Aggregat, welches eine sinnvolle, gedrängte  Bauweise aufweisen soll, so dass es raummässig über  all anzuwenden ist und wegen der wenigen Bauteile  und billiger Herstellungskosten in vielen Betrieben  die Anschaffung und die Montage ermöglicht.  



  Das elektrohydraulische Aggregat zeichnet sich  dadurch aus, dass ein ferngeschalteter Elektromotor,  eine durch diesen direkt oder mittels einer Kupplung  angetriebene hydraulische Pumpe und ein in Abhän  gigkeit von der Drehrichtung des Elektromotors ohne  Umschaltung gesteuerter Kolbenmotor zu einer Ein  heit zusammengebaut sind.  



  Die Zeichnung zeigt beispielsweise Ausführungen  des elektrohydraulischen Aggregates in schematischer    Darstellung.     Fig.    1 zeigt eine Einheit in     Tandemaus-          führung    und     Fig.    2 eine solche in Parallelausführung.  Es bedeuten: 1 Elektromotor, 2 Verbindungsstück,  3 hydraulische Pumpe, 4 Rohrleitungen, 5 Kolben,  6 hydraulischer Zylinder, 7 Verbindungsstück und  8 und 9     Anschlusspunkte    der Einheit.  



  Bei beiden Beispielen sind der ferngesteuerte Elek  tromotor 1, die durch diesen angetriebene hydrau  lische Pumpe 3 und der in Abhängigkeit von der  Drehrichtung des Elektromotors 1 direkt gesteuerte  Kolbenmotor 5, 6 zu einer Einheit zusammengebaut.



      Electro-hydraulic unit for generating linear force movements For the operation of the remote-controlled flaps, slides and other facilities in factories, electric motors with transmission drives or hydro or pneumatic facilities with long pipelines have been used. Because of their high purchase price, these controls were seldom installed in the factory.



  The subject of the invention is an electrohydraulic unit, which should have a meaningful, compact design, so that it can be used in terms of space and because of the few components and cheap manufacturing costs in many companies, the acquisition and assembly.



  The electrohydraulic unit is characterized by the fact that a remotely controlled electric motor, a hydraulic pump driven by this directly or by means of a clutch and a piston motor controlled in dependence on the direction of rotation of the electric motor without switching are assembled into one unit.



  The drawing shows, for example, embodiments of the electrohydraulic unit in a schematic representation. FIG. 1 shows a unit in a tandem design and FIG. 2 shows a unit in a parallel design. They mean: 1 electric motor, 2 connecting pieces, 3 hydraulic pumps, 4 pipes, 5 pistons, 6 hydraulic cylinders, 7 connecting pieces and 8 and 9 connection points of the unit.



  In both examples, the remote-controlled elec tric motor 1, the hydraulic pump 3 driven by this and the piston motor 5, 6 directly controlled depending on the direction of rotation of the electric motor 1 are assembled into one unit.
