Definitions

  • the invention relates to a method for automatically ejecting cartridge cases according to the features of the preamble of claim 1.
  • the invention further relates to a catch lock device for carrying out the method.
  • a method and a device for independently loading and moving the weapon barrel from the loading position into the firing position is known.
  • two springs are tensioned independently of the pipe brake and the pipe recuperator during pipe return. After the barrel returner has brought the barrel into the loading position, a spring causes the barrel to be loaded with a new cartridge. The weapon barrel is then brought into the firing position by relaxing the second spring.
  • EP-B1-0 141 900 it is known to collect empty cartridge cases via a case clearer in the turret of a tank and then to eject them from the area of the tank turret.
  • EP-A3-0 149 014 It is also known from EP-A3-0 149 014 to throw empty cartridge cases out of the tower at the rear by means of an automatically driven ejection device.
  • the empty sleeves are first transported in the firing position after the shot is fired by a sleeve ejector fastened to the base and movable by the opening movement of the locking wedge from the cargo space into the aforementioned devices, by means of which the cartridge cases are removed from the tower area in the second process step.
  • This second process step takes place immediately before the loading of the weapon barrel in an index position to be taken for it.
  • a direct, that is, simultaneous removal of the empty cartridge cases from the cargo space and the tower area solely by the case ejector carrying out the first method step is not possible in the known designs, because with these barrel weapons the barrel advance takes place exclusively in the firing position.
  • the invention has for its object to further develop a method of the type mentioned in such a way that a direct automatic sleeve ejection into the outer region of the armored turret is possible during the barrel advance.
  • a catch lock device for performing the method is to be specified.
  • the catch lock device which is also referred to below as a feed lock device, makes it possible in an advantageous manner to convey the sleeve ejection directly out of the tower in one movement step only during the tube advance through the sleeve ejector arranged within the base piece.
  • This will have disadvantages in terms of Harmonization of a sleeve ejector external to the weapon with automatic loading devices is avoided by eliminating this external sleeve ejector.
  • the immediate removal of the metal sleeves heated by the firing of the shot inside the tower prevents annoyances caused by smoke.
  • the flow stop device is attached to the side of the pipe cradle, so that there are no space restrictions for loading devices behind the weapon.
  • the weapon system is therefore immediately available for the next loading process after the case has been ejected.
  • the design of the flow lock device as a hydraulic piston-cylinder unit enables the gun barrel advance to be interrupted simply and safely by closing an internal check valve until an external valve that can only be actuated in the index position of the gun barrel has opened a bypass line for continuing the barrel advance.
  • FIG. 1 illustrates a tubular weapon 3 that can be adjusted in height about a shield pin axis 2 with a base piece 11 attached to the weapon barrel 5 and a rear side attached to it, as is also shown in particular in FIG. 5 on a tubular cradle 9 that can be pivoted about the shield pin axis 2 arranged, which corresponds to the execution of its function with the base piece 11, as part of the returning mass, and with a tower-fixed guide 29.
  • a known gun barrel return brake 48 and a known barrel retractor 37 are fastened.
  • the device 1 shown in FIG. 2 contains means which interrupt the gun barrel advance in each firing position 6 deviating from an index position 4 of the gun barrel 5 shown in FIG. 3 in the angular range ⁇ and ⁇ until the gun barrel 5 has assumed the index position 4.
  • These means are essentially formed by a hydraulic piston-cylinder unit 7, by a check valve 13 integrated in this unit, by a heat compensation piston 15 and by an externally arranged unlockable valve 18.
  • the hydraulic piston-cylinder unit 7 is formed from a thin-walled cylinder tube 8 and is connected to the tube cradle 9 in a manner not shown. On one side, the cylinder 8 is closed by a bearing bush 34 for a piston rod 10, while the other side is closed by a guide 35 of the heat compensating piston 15.
  • the piston rod 10 is connected to the base piece 11 at one end outside the cylinder 8, while a hollow piston 12 is arranged at the other end , which consists of a cylinder tube 20 resting against the inner wall 19 and a conical receptacle 21 connected to the piston rod 10.
  • the receiving piece 21 contains through bores 22 and the outer end of the cylinder tube 20 has a seat 23 for the check valve 13.
  • the points of the piston 12 to be sealed, the valve 13, the heat compensation piston 15 and the bearing bush 34 are equipped with suitable sealing elements 49.
  • the check valve 13 opens when the weapon barrel returns, the hydraulic medium flowing from the cylinder space 16 surrounding the piston rod 10 through the bores 22 into the cylinder space 14 in front of the check valve 13. During the barrel advance, the check valve 13 is closed under the force of the spring 25, whereby the forward movement of the barrel 5 is interrupted.
  • the heat compensation piston 15, which closes the other side of the cylinder space 14, has a stop 28 on a stop 28 connected to the outside of the cylinder 8 via a guide tube 27 for limiting the stroke. Characterized in that the stroke length of the heat compensating piston 15 is limited by the stop 28, the heat compensating piston 15 is able to follow the returning piston 12 and in particular the hydraulic medium released by the piston rod 10 only in the limited stroke length a under the force of a spring 36. It thus arises in the pipe return in the cylinder chamber 14 due to the extending piston rod 10, a shortage of hydraulic fluid that is not compensated for by the heat compensation piston 15.
  • a guide 29, shown in FIGS. 3 and 4 is provided in a tower-proof manner in a manner not shown in the tower, whereby the valve 18 is mechanically actuated via a trigger lever 30 sliding in the guide 29 can be.
  • This guide is structured like a segment and arranged in a circle around the shield pin axis 2, the guide plane 31 in the region of the index position 4 of the weapon barrel 5 contains a protruding cam 32, which assumes, for example, a sinusoidal curve 33 for triggering the lever 30.
  • the locking wedge 38 shown in FIG. 6 is opened within the base piece 11 in a known and therefore not shown manner, cams 39 arranged on the locking wedge 38 when the locking wedge 38 is moved laterally into the downward direction Direction 50 meet a stop 40 of a known sleeve ejector 41 and initiate a pivoting movement about its axles 52 mounted in the base piece 11, whereby its arms 42 arranged on both sides detects a cartridge case 44 from the cargo space 45 (FIG ) convey.
  • the rotational energy of the sleeve ejector 41 is dimensioned such that the cartridge case 44 leaves the region of the tower 47 om arrow direction 51 in a direct way through the base piece 11 and through a bore 46 in the tower wall.
