Definitions

  • the invention relates to a device for supplying ammunition to a machine gun movable about a horizontal axis in a carriage of an armored vehicle or the like, in particular to a machine gun for a cartridge caliber up to 40 mm, with a feed chute leading from a cartridge magazine to the weapon, said magazine , Feed shaft and weapon can be rotated together with the mount around its vertical axis.
  • a device of the type mentioned at the beginning (armored personnel carrier Marder) is known, in which the ammunition strapped by means of a decay belt is located in zigzag layers in a box magazine arranged below the machine gun. The cartridge belt is then conveyed from this box magazine into a loop bearing in front of the weapon, in which a supply for a burst of fire can be arranged in at least one hanging loop.
  • the arrangement has been made so that the machine gun or the like is able to automatically pull the belt with the cartridges from the loop supply during the burst of fire.
  • the object on which the invention is based is seen in creating a device of the type mentioned at the outset which, while avoiding the disadvantages mentioned, completely dispenses with a decay belt with belt members which are used up and are used only once, ie. H. no belt is required in the respective magazine, and is nevertheless able to feed the weapon even more reliably with ammunition.
  • an endless conveyor belt made of flexible-elastic material running from the magazine through the feed shaft to the closure piece and back to the magazine, which in its entirety can be driven intermittently or continuously by a power source independent of the weapon and along one side having flexible-elastic cartridge receptacles, and the magazine and a second deflection close to the stopper, by which the P atronenfactn are so bent up by a first deflection in the region in a reversible manner, that each of the closure member upstream Hältelippen or the like pending cartridge from the carrier of the Breech can be inserted into the chamber of the weapon.
  • the flexible-elastic, revolving, endless conveyor belt takes the cartridges from the magazine at its reversal point assigned to the magazine and conveys them to the closure piece, being able to move via rollers and reversing wheels run and due to its flexibility, for example, also follow the guide through the likewise flexible guide element, the torsion and bending of which also change with changing elevation of the weapon or machine cannon, if such a guide element is required in individual cases.
  • a guide element is known, is manufactured by Nobels Industries Inc., St. Paul / Minnesota, USA, and can also be changed in length if necessary. The extent of the possible change results from the length and thus the number of individual, mutually displaceable members of this known guide element.
  • the advantages of the invention consist primarily in the fact that the ammunition arranged in the magazine or in the magazines can be stored without belts, that the ammunition or cartridges from the respective magazine are automatically taken up by the conveyor belt and that the work of refilling one Belt does not apply. Furthermore, since a decay belt with individual, lost belt members is no longer available, the costs in this regard are no longer incurred. For a given volume of a magazine, a larger number of cartridges can be stored in it than would be the case if a belt were used. Furthermore, the susceptibility to failure caused by belt members has been eliminated.
  • the flexible conveyor belt is advantageously made of rubber-elastic material with inserts made of metal or textiles.
  • rubber material is used, optionally with inlays made of one or more fabrics or braids, for example made of textile fibers.
  • the inlays give the material the required tensile strength and stability, while the rubber provides the rubber-elastic properties, whereby the inlays allow a certain stretch of the conveyor belts also in length.
  • the cartridge holders can be molded into the material as soon as the conveyor belt is manufactured.
  • the conveyor belt is expediently a toothed belt, which is driven by at least one toothed wheel. Such a positive drive is particularly reliable.
  • the cartridge receptacles of the conveyor belt consist of essentially semicircular grooves, which are arranged parallel to one another transversely to the longitudinal axis of the conveyor belt and whose diameter is equal to or smaller than the diameter of the cartridge cases. This ensures a reliable, firm, yet detachable fit of the cartridges in the grooves of the conveyor belt.
  • the cartridge receptacles are expediently arranged on the outside and the teeth on the inside of the rotating conveyor belt designed as a toothed belt. This design enables the Auskeh'_Institut to inevitably bend open at the reversal points in such a way that the sleeves of the cartridges can be inserted or pushed out particularly easily. For each shot, a cartridge is again picked up from the magazine by the cartridge receptacles of the conveyor belt run back empty to the magazine and can be conveyed to the weapon.
  • two conveyor belts can be provided, each of which rotates from an associated magazine through a feed shaft to the closure piece and back to the respective magazine, the two deflections being arranged parallel to one another on a support upstream of the closure piece, which in the The level of the two deflections can be shifted in two functional positions in such a way that the driver of the closure piece can come to rest either on the cartridge offered by one or on the offered cartridge of the other conveyor belt.
  • This configuration ensures a simple switch of the weapon to two different ammunition. Types, for example explosive ammunition on the one hand and armor-piercing ammunition on the other. To do this, the support must only be moved to one of its two end positions.
  • the double belt feeder which is otherwise always required when using two types of ammunition, can be dispensed with, which advantageously increases the installation length for a flexible guide element of the type mentioned above if the end of the feed shaft is arranged at a fixed distance, if such is necessary for the reasons already mentioned. When the weapon is raised, this reduces the specific load on the flexible guide element (angle per unit length) and the conveyor belts guided therein.
  • the toothed belt has, in cross section, two flat guide seams on its two sides and centrally a thickened region which has the cartridge receptacles on its outside and the teeth on its inside.
  • the guide hems are particularly useful where there are bends between the magazine and the closure piece on the way of the conveyor or toothed belt.
  • Each run of a toothed belt between the magazine and the deflection preferably has at least one bending region, in which the toothed belt is guided on the top and / or bottom of its guide seams by means of roller bearings which are preferably mounted in an oscillating manner.
  • the length of the cartridge receptacles suitably corresponds essentially to the width of the conventional belts, in particular decay belts.
  • two feed shafts 2 and 3 are provided, each of which leads from a magazine 4 or 5 to the gun 1.
  • the magazine 4 is a ring magazine with, for example, explosive cartridges 6, while the magazine 5 is a box magazine with armor-piercing ammunition 7.
  • the magazines. 4 and 5, the feed chutes 2 and 3 and the weapon 1 can be rotated about its vertical axis 8 together with an armored turret, not shown.
  • the weapon 1 itself is movable about a horizontal axis 9 with respect to its elevation.
  • a torsion consisting of a plurality of individual elements 13 which can be displaced relative to one another and bending-variable guide element 14 or 14 'is provided, which enables an elevation of the weapon.
  • Each conveyor belt 15 or 16 has flexible-elastic cartridge receptacles 18, 19 along one side thereof. Furthermore, a deflection 20, 21 is arranged near the closure piece 12, through which the cartridge receptacles 18, 19 can be bent open in a reversible manner (FIG.
  • the two deflections 20, 21 are arranged parallel to each other on a support 25 upstream of the closure piece 12, which is displaceable in the plane of the two deflections 20, 21 in the direction of the double arrow A to two sides in two functional positions, such that the driver 24 of the Breech piece 12 can come to rest either on the next cartridge 7a of one or on the next cartridge 6a of the other conveyor belt 16 or 15.
  • the weapon 1 shoots armor-piercing cartridges 7 from the magazine 5.
  • the support 25 In the position shown in FIG. 1a, however, the support 25 is in its upper end position or functional position, in which the weapon 1 detonating ammunition 6 shoots the ring magazine 4, which is apparent on the one hand from the relative position of the ammunition to the driver 24 on the one hand and the different functional positions of the support drawn with solid and dashed lines on the other hand.
  • the respective flexible conveyor belt 15, 16 consists of rubber-elastic material with inserts made of metal or textiles.
  • the material can be Neoprene ® and the inlays can be one or more fabrics that are not shown in detail.
  • the conveyor belts are toothed belts, which are driven by at least one gear wheel. In the case of the toothed belt 15, this gear sits behind the bevel gear 26, in the case of the toothed belt 16 behind the bevel gear 27 of the transmission driven by the electric motor 17 and explained in more detail below. Both gears engaging in the teeth 28 of the respective toothed belts 15 and 16 (FIG. 2) are therefore not visible.
  • the cartridge receptacles 18, 19 of the conveyor belts 15, 16 consist of essentially semicircular grooves 28 and 29, which are arranged parallel to one another transversely to the longitudinal axis of the conveyor belts 15, 16 and whose radius of curvature is equal to or less than the radius of curvature of the cartridge cases in the gripped area.
  • the cartridge receptacles are thus able, with their finger-like projections 30, to enclose a substantial area of the wall of the cartridge cases firmly, but elastically or resiliently, and thus also to hold them in the area of bends as can be seen from the left part of FIG. 2 .
  • the cartridge receptacles 18, 19 are expediently arranged on the outside and the teeth 28 on the inside of the rotating toothed belts 15, 16, these sides being defined by the direction of rotation.
  • cartridges 6, 7 are again picked up from the magazines 4, 5 by the cartridge receptacles 18, 19 of the runs of the conveyor toothed belts 15, 16 returning empty to the magazines 4, 5 and conveyed to the weapon 1.
  • the transfer from the magazines 4, 5 to the toothed belt 15, 16 takes place either by means of a chain conveyor 31, which works together with a star wheel 32, which sits on an axis 33 with the toothed wheel 15, not shown, driving the toothed belt 15, or with the aid of the individual shafts 34 of the box magazine 5 pressure pieces 35 which press the cartridges 7 down into the cartridge receptacles 19 of the toothed belt 16.
  • the toothed belts 15, 16 have two flat guide seams 36 and 37 or 38 and 39 in cross-section on both sides, and a central, thickened area 40 or 40 ', the cartridge receptacles 18 and 19 on the outside and on the inside the teeth 56 has (Fi g. 3 and 4).
  • the width X of the cartridge receptacles 18, 19 substantially corresponds to the width of a conventional disintegrating g urtes. Since FIG. 3 shows the region of the reversal points 20 and 21, the elements 13 of the flexible guide element 14 are also visible, which has been omitted in FIGS. 5 and 5a for the sake of clarity.
  • the reversing wheel 41 rotating clockwise according to arrow B for the toothed belt 15 and the corresponding reversing wheel 42 rotating counterclockwise in the direction of the arrow C, which are respectively seated on axes 43 and 44, can also be removed.
  • the toothed belt 16 in particular clearly shows how the guide seams 38 and 39 slide on the inside of the elements 13 towards the reversing wheel 42.
  • each strand of a toothed belt 15, 16 between the respective magazine 4, 5 and the deflection 20, 21 has at least one bending region 45, 46, in which the respective toothed belt 15, 16 on the The top and / or bottom of its guide hems 36, 37 and 38, 39 is guided by means of roller bearings 47, 48, 49 and 50, which are preferably oscillating. This ensures a low-friction and uniform guidance of the toothed belts 15, 16 also at the reversal points 45 and 46.
  • the toothed belt 15 conveys the cartridges 7 from the ring magazine 4, it passes a deflection roller 54 which, in the manner indicated by dashed lines, at 55 is provided with depressions corresponding to the finger-like projections 30 of the toothed belt 15, in such a way that not only a frictional but also a form-fitting drive of the deflection roller 54 takes place through the toothed belt 16.
  • FIG. 6 shows an example of an embodiment of a possible drive for the toothed belts 15, 16, a gear transmission being shown which is driven by an electric motor 17 for reasons of clarity.
  • a sliding pinion 52 is arranged in the direction of the double arrow D, which in the position shown in solid lines on the one hand with the drive of the bevel gear 26 for the toothed belt 15 and on the other hand with the drive 53 for the ring magazine 4 in engagement is, while it meshes with a drive for the bevel gear 27, which is assigned to the drive of the toothed belt 16, in the case of a shift upwards into the position shown in broken lines.
  • the ring magazine 4 is only shown in cross section, but it can be easily recognized that it is arranged concentrically around the vertical axis of rotation 8 of the armored turret not shown and containing the weapon 1.
  • the driver 24 or the breech of the weapon breech 12 pushes the respective cartridge 6a or 7a out of the holding lips 22 or 23 into the cartridge chamber of the weapon, not shown.
  • a burst of fire consisting of several shots, i.e. in the case of continuous fire with a cadence of, for example, 800 to 1000 shots per minute, corresponding to 15 to 16 shots per second.
  • the purely theoretical, progressive toothed belt movement becomes a continuous process.
  • the belt section that respectively returns after the deflection rollers 41 and 42, or the respectively returning strand, is empty and therefore moves outside the flexible guide element consisting of the elements 13 that are movable relative to one another and nevertheless held against one another.
  • this returning belt section is guided in particular on bends by rollers.
  • this belt section also runs in a guide shaft. Both such guide shafts and the feed shafts 2 and 3 serve not only to protect the toothed belt and possibly the cartridges carried by it, but also to guide it and prevent vibrations.
  • the flexibility and elasticity of the toothed belt helps to even out the acceleration or deceleration forces that may occur, especially since it can be bent, twisted, lengthened or shortened within predetermined tolerances without the reliability of the cartridge feed to the weapon 1 being impaired thereby.
