Definitions

  • the invention relates to a hydraulic drive according to the preamble of the claim 1.
  • the spring arrangement runs perpendicular to the direction of movement of the piston, whereby due to the fact that only one spring arrangement is provided, asymmetrical Apply forces to the hydraulic drive.
  • the object of the invention is to provide a hydraulic drive of the type mentioned to create that is further simplified.
  • the hydraulic drive 10 has a cylinder body 11, in which there is a working cylinder 12, in which a working piston 13 is movably guided.
  • a pressure cylinder body 16 fastened which has a cylinder space 17 in which two pressure pistons 18th and 19 are movably guided.
  • the cylinder space 17 between the two pressure pistons 18 and 19 is filled with pressurized fluid.
  • a pressure piece 20 and 21 against which one end of a spring arrangement 22 and 23 is applied.
  • the other end of the two spring arrangements are each supported on a support plate 24, 25, which means Screw connections 26 and 27 are rigidly connected to the pressure cylinder body.
  • Screw connections 26 and 27 are rigidly connected to the pressure cylinder body.
  • the cylinder body is made of drawn material manufactured, into which the working cylinder 12 and line bores 36, 37 are introduced are to the pressure cylinder space 37 with a pump low pressure tank device 38, a switching control valve 39 to connect and beyond the room below and to supply or remove pressure fluid above the piston 13.
  • the pressure piston 40 moves in the direction of the arrow P to the right, with it Movement lifts the pressure piece 21 from the end face of the pressure cylinder body 16 while tensioning the spring assembly 23. Since with the pressure piece 21, the support piece 24 of the spring arrangement 22 is connected, the support piece also moves 24 to the right in the direction of arrow P, this also resulting in the spring arrangement 22 is excited.
  • the fixation of the pressure cylinder body 16 on the switch-side end face of the Cylinder body 11 is made by means of screw connections 43.

Claims (7)

  1. Système d'entraínement hydraulique comprenant un agencement de cylindre-piston d'entraínement dont le piston de travail (13) entraíne, en passant par une tige de piston (14), un dispositif d'actionnement, de préférence un disjoncteur de puissance à haute tension, comprenant un agencement de cylindre-piston de poussée (19, 16) qui fournit du fluide sous pression pour la commande de l'agencement de cylindre-piston de travail (13, 11, 12), et un agencement accumulateur à ressort (16, 17) dont l'énergie accumulée est transmise à l'agencement de cylindre-piston de poussée (29, 36), caractérisé par le fait que l'agencement de cylindre-piston de poussée (16, 17, 18, 19 ; 40) présente au moins un piston de poussée (18, 19 ; 40) qui est mobile transversalement à la direction de déplacement du piston de travail (13) et qui coopère avec deux agencements de ressort (22, 23) disposés symétriquement par rapport à ce dernier et ayant des directions d'action s'étendant transversalement à la direction de mouvement du piston de travail (13).
  2. Système d'entraínement hydraulique suivant la revendication 1, caractérisé par le fait qu'il comprend deux pistons de poussée (18, 19) entre lesquels se le fluide sous pression.
  3. Système d'entraínement hydraulique suivant la revendication 2, caractérisé par le fait que les pistons de poussée (18, 19) agissent de préférence chacun en passant par une pièce de poussée (20, 21) sur l'agencement de ressort (22, 23) correspondant en vue du chargement des agencements de ressort (22, 23).
  4. Système d'entraínement hydraulique suivant la revendication 2 ou 3, caractérisé par le fait que les extrémités extérieures des agencements de ressort (22, 23) portent respectivement contre une pièce d'appui (24, 25) disposée de façon stationnaire.
  5. Système d'entraínement hydraulique suivant la revendication 1, caractérisé par le fait qu'un seul piston de poussée (40) est monté de façon mobile dans le cylindre de poussée (17), ce piston étant couplé par une pièce de poussée (21) avec l'un des agencements de ressort (22, 23) et que la pièce de poussée de l'un des agencements de ressorts (22, 23), couplée avec le piston de poussée (40) est reliée rigidement à la pièce d'appui de l'autre agencement de ressort (22, 23) de manière que lors du déplacement du piston de poussée (40), la pièce de poussée de l'un des agencements de ressort et la pièce d'appui de l'autre agencement de ressort se déplacent conjointement avec le piston de poussée (40) et dans le même sens que ce dernier.
  6. Système d'entraínement hydraulique suivant l'une des revendications précédentes, caractérisé par le fait que le piston de poussée (18, 19 ; 40) est disposé dans un corps de cylindre de poussée (16) qui s'étend transversalement à la longueur ou à la direction de mouvement du piston de travail (13).
  7. Système d'entraínement hydraulique suivant la revendication 6, caractérisé par le fait que le corps de cylindre de poussée est fixé au corps de cylindre (11) pour le piston de travail (13) sur la face frontale de ce corps éloignée du disjoncteur.
