Definitions

  • the invention relates to a mass locking weapon locking system with a lockable in a closure housing a corresponding weapon lockable part and an elastic closing element.
  • a weapons locking system for example, in the US 2 497 350 A described.
  • a hydraulic brake integrated in the closure is installed. This changes the time course of the power transmission and thus reduces the amount of force acting on the shooter or a gun carriage or in the case of large-caliber weapons on the cradle.
  • the brake decouples the movement of the closure from the movement of the weapon housing.
  • the weapon barrel of the corresponding weapon is closed at the rear by a heavy closure part (closure block), wherein the closure part is slidably disposed in a locking housing of the weapon axially adjacent to the weapon barrel and by an elastic closing element (Vorholer), in which it is usually a closing spring, is acted upon (see, for example: Rheinmetall "weapons technical paperback", Dusseldorf, 7th Edition 1985, pages 248 ff ).
  • the invention has for its object to provide a mass-lock system, which ensures high reliability and which is also connected to the firing of high-performance ammunition with no significant increase in weight.
  • the invention is essentially based on the idea of integrating the closing element into or into the closure part. It is achieved by a connected in series with the closing element and also arranged in the closure part hydraulic translation that the closing spring can have a relatively small length and its characteristic only a relatively flat increase in force.
  • the closure part is not formed as a solid closure block, but as a hollow cylinder, wherein the cylinder chamber is divided according to independent claim 1 by an axially displaceable balance piston and independent claim 6 by an elastic closing element, in two partial cylinder spaces.
  • independent claim 1 seen in the shot direction of the corresponding weapon, rear side and filled with a brake fluid first Operazylinderraum arranged an axially displaceable piston which is connected to a piston rod, which passes axially through the rear wall of the closure part and is connected at its end facing away from the piston with the closure housing.
  • the elastic closing element In the second part of the cylinder space, the elastic closing element is arranged, which holds the balancing piston in a starting position, such that when the closing part returns by the piston moving into the first partial cylinder space, the compensating piston is moved towards the closing element and the closing element is tensioned.
  • closure system according to the invention has the advantages that the closing element is well encapsulated and therefore environmental influences have only a small influence on this element. It has also been shown that this closure system has a high reliability and the clamping force of the closing element is very constant.
  • the closing element is, according to dependent claim 2, preferably a compression spring, which is supported at its one end to the balance piston and at its other end to the front wall of the closure part.
  • the rear-side partial cylinder space together with the piston and the piston rod form a plunger cylinder (plunger cylinder), i. a cylinder in which the piston rod also serves as a piston, so that the cylinder is characterized by a simple and robust structure.
  • plunger cylinder plunger cylinder
  • a mass locking weapon locking system which is arranged in a closure housing 2, which connects at the rear to the cartridge chamber of a gun barrel, not shown.
  • the Waftenver gleichsystem 1 essentially comprises a in the closure housing 2 axially displaceable closure part 3, which also contains the reasons not shown for clarity, required for firing and for removing the cartridge after firing elements.
  • the closure part 3 is formed as a hollow cylinder, wherein the cylinder chamber 4 is divided by an axially displaceable compensating piston 5 in two partial cylinder chambers 6, 7.
  • first partial cylinder chamber 6 is filled with a brake fluid (usually oil) 8.
  • a brake fluid usually oil
  • an axially displaceable piston 9 is arranged, which is connected to a piston rod 10.
  • the piston rod 10 is guided axially through the rear-side wall 11 of the closure part 3 and is connected at its end facing away from the piston 9 with the closure housing 2.
  • the first partial cylinder space 6 together with the piston 9 and the piston rod 10 form a plunger cylinder.
  • an elastic closing element 12 is arranged, which is a closing spring designed as a compression spring.
  • the closing spring 12 is supported with its one end 13 on the balance piston 5 and with its other end 14 on the front wall (shock bottom) 15 of the closure part 3 from.
  • the closure part 3 After the return of the closure part 3 is completed ( Fig. 2 ), the closure part 3 is displaced by the force acting on the balance piston 5 force of the closing spring 12 in the weft direction ( Fig. 3 ) until it has returned to its starting position ( Fig. 1 ).
  • an elastic closing element can be used instead of, for example, the closing spring 12, an elastic rubber and / or plastic part (bulky) or a gas spring or compressible gas.
