Claims (7)

  1. Ein hydraulischer Linearantrieb, welcher folgendes umfasst: einen gepanzerten Teilbereich, der konzentrische Zylinder aufweist; und einen nichtgepanzerten Teilbereich, der einen Zylinder mit einem zerbrechlichen Kolben und einer zerbrechlichen oberen Dichtmutter aufweist.
  2. Der hydraulische Antrieb nach Anspruch 1, welcher weiterhin folgendes umfasst: Leckentlüftungen, die zur Vermeidung von Lecks zwischen hydraulischen Systemen zur Versorgung der Zylinder ausgebildet sind.
  3. Der hydraulische Antrieb nach Anspruch 1, welcher weiterhin folgendes umfasst: eine Stopfbuchse zur Abdichtung eines Endes des nichtgepanzerten hydraulischen Antriebs; einen Fühler, der so ausgebildet ist, dass ein aufgrund der Beschädigung der Stopfbuchse entstandenes Fluidleck detektiert werden kann.
  4. Der hydraulische Antrieb nach Anspruch 1, wobei der gepanzerte Teilbereich und der nichtgepanzerte Teilbereich aneinander in Form einer Tandemanordnung angrenzen.
  5. Ein hydraulisches dreifaches Antriebssystem, welches folgendes umfasst: einen gepanzerten, doppelten, konzentrischen, hydraulischen Linearantrieb; einen nichtgepanzerten hydraulischen Linearantrieb; wobei der doppelte, konzentrische, hydraulische Linearantrieb und der nichtgepanzerte hydraulische Linearantrieb aneinander in Form einer Tandemanordnung angrenzen.
  6. Das hydraulische Antriebssystem nach Anspruch 5, welches weiterhin folgendes umfasst: Leckentlüftungen, die zur Vermeidung von Lecks zwischen hydraulischen Systemen zur Versorgung der Antriebe ausgebildet sind.
  7. Das hydraulische Antriebssystem nach Anspruch 1, welches weiterhin folgendes umfasst: eine Stopfbuchse zur Abdichtung eines Endes des nichtgepanzerten hydraulischen Antriebs; einen Fühler, der so ausgebildet ist, dass ein aufgrund der Beschädigung der Stopfbuchse entstandenes Fluidleck detektiert werden kann.
