Definitions

  • the invention relates to ammunition containers of an automatic loading device according to the preamble of claim 1.
  • a tape magazine of an automatic loading device is known, which is arranged in a flat design in the turret of a main battle tank in order to save the largest possible number of cartridges, if necessary in various types of ammunition, in close proximity to weapons and to ensure a time-saving cartridge feed.
  • the belt magazine conveys the cartridges in conveyor trays transversely to the longitudinal axis of the cartridge to a deflection point, from which they are pushed out of the magazine via a deflection lever and pushed into a landing tube.
  • the individual links of the conveyor shells are rotatably connected to one another in the cartridge axis and guided in the circumferential direction.
  • the conveyor bowls form partial ammunition containers for holding horizontally stored cartridges.
  • thin-walled ammunition preferably battle tank ammunition with a combustible sleeve
  • the invention is advantageously characterized in that the ammunition containers are now able to stably hold cartridge ammunition with multiple diameters in their entire length range and, regardless of existing tolerances on the ammunition or on the ammunition container, by swiveling holding clamps arranged several times on the ammunition container in the storage position to be attached without movement.
  • both retaining clips Due to a one-sided arrangement of the retaining clips on the same long side of the ammunition container and by the possibility of coupling the opening and closing mechanisms of both retaining clips during the opening stroke, both retaining clips are simultaneously and uniformly from the holding position surrounding the cartridge ammunition to an opening position releasing the cartridge ammunition via only one external opening mechanism swivels.
  • each opening and closing mechanism contains a lifting lever which is rotatably connected to the retaining clip at one end and contains a bore at the other end for receiving an eccentric arranged on a drive shaft of the opening and closing mechanism. Due to the fact that between the eccentric and the lifting lever there is a self-locking securing device which is prestressed in the closing direction by torque-generating prestressing means, each holding clamp is held securely in the closed position.
  • the mutually facing ends of the drive shaft contain couplable form-locking means, the form-locking means arranged on a drive shaft being designed as an automatically drivable opening lever and the form-locking means located on the other drive shaft being designed as a driver provided with a shoulder, and the opening lever and the shoulder of the driver are arranged in such a way that the driver is only connected to the opening lever in the towing position during the opening process of the retaining clips, so that the retaining clips can assume their closing positions independently of one another, but permit a common opening.
  • the cartridge ammunition can be advantageously ejected evenly and gently parallel to the ammunition container axis during the opening process of the holding clips from the ammunition containers by the arrangement of an ammunition ejector arranged on the drive shaft in the functional area of the holding clips.
  • the shell shape of the ammunition container in the region of the base of the case is designed such that, in the case of a horizontally rotating band magazine, the holding clips are always arranged on the outside either on the top side or on the bottom side of the ammunition container, horizontally mounted cartridge ammunition is advantageously at the rear turning point of the magazine when the holding clips are open can be picked up obliquely from above and can also be ejected obliquely downwards at the front turning point, also with the holding clips open.
  • the entire ammunition container 1 is shown as part of a tape magazine 35 shown in Fig. 15 of an automatic loading device for barrel weapons, not shown.
  • the ammunition container 1 contains a shell 2, which is semicircular in cross-section, the inner diameter of which is offset several times in order to hold thin-walled ammunition 3, preferably main battle tank ammunition with a combustible sleeve.
  • the cartridge ammunition 3 is supported once in the area 4 of the projectile head 5 and in area 6 of the sleeve base 7.
  • the inner diameter d the conveyor shell 2 in the area 4 is smaller than the inner diameter d 2 in the area 6.
  • the ammunition container 1 is provided with reinforcing ribs 42 in the receiving area 4 of the comparatively heavy projectile head 5 in the outer area. So that the ammunition 3 can be placed in the areas of the stable case bottom 7 and the projectile head 5, the ammunition container 1 is designed in the area of a combustible propellant charge sleeve 41 in a manner not shown.
  • the ammunition container 1 contains end walls 45, 46 as the axial limitation of the ammunition 3, the end wall 45 being integrally connected to the ammunition container 1 as a loose flange via screw connections according to the hole pattern arrangement of FIG. 10 and the end wall 46.
  • the ammunition container 1 is provided in the areas 4, 6 on the same longitudinal side 8 with two pivotable retaining clips 9, 10 which partially surround the cartridge ammunition 3 in the circumferential direction.
  • the retaining clip 9 is pivotally arranged by an opening and closing mechanism 12 about a rigid axis 47 attached to the container 1, while the retaining clip 10 is pivotably arranged by an opening and closing mechanism 11 about a rigid axis 48 attached to the container 1.
  • the opening and closing mechanism 11, 12 consists essentially of a lifting lever 16 which is rotatably connected at one end 17 to the holding clip 9, 10 and at the other end 18 a bore 19 for receiving an eccentric arranged on a drive shaft 20, 21 22 contains.
  • the drive shafts 20, 21 are arranged offset from one another and are mounted in the areas of the holding clips 9, 10 on the ammunition container 1, the shaft 21 being additionally mounted in a bearing 50 in the area 4.
  • the drive shafts 20, 21 each contain, in the closing direction 15, torque-generating mechanical pretensioning means 13, 14, which consist of spiral springs 37, 38 wound around the drive shafts 20, 21 , the ends of which are fastened on the one hand to a pin 39 of the drive shafts 20, 21 and on the other hand to a pin 40 arranged on the ammunition container 1.
  • the mutually facing ends of the drive shafts 20, 21 contain, according to FIGS. 5, 12, form-locking means 25 that can be coupled, the form-locking means 25 arranged on the drive shaft 20 being designed as an automatically drivable opening lever 26 and the form-locking means 25 located on the drive shaft 21 as a driver 28 has an approach 27.
  • the extension 27 of the driver 28 and the opening lever 26 are arranged with respect to one another in such a way that the driver 28 is connected to the opening lever 26 only in the trailing position 29 during the opening process of the holding clips 9, 10.
  • both holding clamps 9, 10 can be swiveled out uniformly from a holding position 23 surrounding the cartridge-like ammunition 3 in the opening direction 51 (FIG. 13) via only one opening drive (not shown) through the opening lever 26 and the respective opening and closing mechanisms 11, 12.
  • the shoulder 27 of the driver 28 ensures a separate return stroke of the holding clips 9, 10 in the closing direction 15 (FIG. 14), so that the holding clips 9, 10 correspond to the respective existing ammunition diameters in the areas 4, 6 can adjust.
  • the lifting lever 16 is each connected to the holding clamps 9, 10 via a fine adjustment device 30.
  • the fine adjustment device 30 consists essentially of a pin 49, which is guided in the holding clip 9, 10 and is designed as an eccentric 31 in the guide area of the lifting lever 16. The fine adjustment can be carried out for each holding clip 9, 10 from the outside, even when the ammunition container 1 is installed will.
  • each drive shaft 20, 21 in the functional area of the holding clips 9, 10 contains an ammunition ejector 32 equipped with the lever 33, as shown in FIG. 6.
  • each ammunition container 1 is connected on both end faces 43, 44 (FIG. 2) on the supporting bolts 53 of the end walls 45, 46 (FIG. 2) to the subsequent ammunition container 1 via tabs 54.
  • the casing shape 34 (FIG. 3) of the ammunition container 1 is designed in the region 6 (FIG.
