Definitions

  • the present invention relates to a method of attaching a modern auxiliary armor to a base armor of vehicles or stationary equipment. Furthermore, the subject of the invention is a fastening produced by the method.
  • Modern auxiliary armor for armored vehicles must meet the highest ballistic requirements.
  • the additionally applied armored protection of the vehicles is divided into individual additional armor elements, which are individually mounted individually to the vehicle structure.
  • the individual additional armor elements are made as large as possible, since each gap and the edge region of each element represents a weakening of the armor.
  • the elements are precisely adapted to the vehicle structure and just chosen so large that they can still be manipulated manually.
  • the improvised explosive devices also known as improvised explosive devices or short IED, in which large amounts of explosive, often still surrounded by splinter-capable material, are detonated in the immediate vicinity of vehicles to detonate the gaps between the individual additional armor elements grown clear weak points, which are penetrated by high-energy finest splinters and therefore should be avoided as possible.
  • the additional armor plates each have a plurality of recesses, through which they are put on threaded inserts, which are welded on the base armor, and screwed.
  • An exemplary embodiment is in the EP 1679484A1 shown.
  • the additional armor plate on a threaded socket, which is welded to the base armor, plugged and screwed in this with a specially shaped screw a disc-like pressure plate for holding down the additional armor elements.
  • a weakening of the armor structure is given by the ballistically weaker design of the pressure plate and the threaded bushing and screw.
  • the present invention has for its object to propose a method of attachment or attachment of each additional armor plates, which allows both a weight-optimized, accurate and reliable attachment of the individual elements on the base armor, as well as the thread-related weaknesses and manufacturing tolerances caused gaps between the The invention achieves the object according to the characterizing features of claims 1 to 16.
  • the invention therefore consists essentially in that the individual additional armor plates are arranged with a larger gap to each other, and the space is filled with a clamping element.
  • the clamping element is secured by means of e.g. a screw and a pressure plate pressed into the space between the additional armor plates and thus wedged with these at the lateral contact surfaces.
  • Fig. 1 shows in connection with the Fig. 2 to 6 for example, the attachment of two additional armor plates 1 on the basic armor, not shown here.
  • the two additional armor plates 1 between two welded to the base armor side rails 2, 14, which in exemplary embodiments in FIGS. 12 and 13 are inserted, with a clear gap 20 (FIG. Fig. 2 ) remains between the two additional armor plates 1 remains.
  • suitable fastening devices the basic armor provided.
  • here is a screw fastening 5 in a threaded joint 6 welded onto the base armor (FIG. Fig. 5, 6 ), but as well as any other attachment method can be selected.
  • the clamping element 10 under the pressure plate 3 is pressed into the intermediate space 20 by tightening the screws 5. In the tightened state so that the clamping element 10 is non-positively together with the additional armor plates 1, and in a wedge-shaped design of the clamping element 10 also positively connected to the base armor.
  • Fig. 2 shows a cross section AB with a possible embodiment of the wedge-shaped clamping element 10, wherein the wedge angle of the clamping element 10 are shown only by way of example and any other angle outside the self-locking area can also be performed. Due to the chamfering of the contact surfaces 9, a snug fit can be achieved, as well as a reliable attachment of the additional armor plates 1 is achieved by the form and frictional connection thereby given.
  • the clamping element 10 is in addition to the additional armor plates 1 also made of a ballistic protective material, for. As high-strength steel, ceramic or a ballistic composite material and ensures the ballistic protection between the additional armor plates 1 safely.
  • the contact surface 9 can be provided either on the wedge-shaped clamping element 10 or the additional armor plates 1 or on both surfaces with a friction-reducing layer.
  • Fig. 3 shows the cross section AB Fig. 1 with an alternative embodiment of the clamping element in a two-part embodiment 16, 17, wherein also here the lateral boundaries 9 of the additional armor plates 1 and the clamping elements 16, 17 are chamfered, so that the clamping takes place positively and non-positively.
  • the clamping takes place by tightening the screw 5, which thereby presses on the pressure plate 3 and the two clamping elements 16, 17 against each other along the sliding surface 4 shifts and thereby pressed against the tapered side surfaces 9 of the additional armor elements 1.
  • the chamfer angles of the side surfaces 9 and the angle of the sliding surface 4 are shown only by way of example and can be replaced by other angles. Likewise single or all sliding surfaces are also provided with a friction-reducing surface.
  • Fig. 4 shows analog Fig. 3 a cross section AB through a further alternative embodiment of the two-part clamping element 7, 8, in which otherwise the same design, the side surfaces 9 of the additional armor elements 1 and the two-part clamping element 7, 8 are not bevelled but are at right angles to the base armor, and therefore the clamping only frictionally.
  • Fig. 5 shows a cross section CD by an exemplary attachment by means of fastening screws 5, the screw when screwing in a welded on the basic armor 6 not shown here threaded sleeve 6, the pressure plate 3 (or 15) in the Fig. 8, 9 depresses.
  • another method of attachment can be chosen in which the clamping element 10 is pressed into the intermediate space 20 between the additional armor plates 1.
  • an embodiment not shown here is mentioned, in which the clamping element 10 is not pressed from above by means of a screw 5 and a pressure plate 3 in the intermediate space 20, but screwed through the base armor from the back and pulled with the pressure plate 3 into the gap 20 ,
  • Fig. 6 time a longitudinal section EF through the clamping element, wherein here by way of example three welded onto the base armor threaded sleeve 6 are shown, but also any other number of Butz can be selected, which is required for secure attachment.
  • an undivided in the longitudinal direction of the gap 20 clamping element 7, 8 or 16, 17 or 10 is exemplified, just as the clamping element can also be divided into several individual elements.
  • the individual clamping elements may also be coated with a shock absorbing material or provided with a spacer.
  • Fig. 7 shows a view of the attachment of the clamping element, wherein the individual clamping elements analog Fig. 6 between the slugs 6, in the intermediate space 20 between the additional armor plates 1 on the not shown here Base armor are attached, are arranged and held down by the overlying pressure plate 3.
  • a further edge-limiting strip 11 is shown on a non-clamped edge, which may be bevelled similar to the side strips 2, 14 to ensure a better fit of the additional armor plate 1 with the basic armor.
  • the deckle bar 11 and sidebar 2 need not cover the entire panel edge area, but may also cover one or more shorter sections 12, 13 to facilitate further weight and cost optimization. In extreme cases, this can also be done by individual pins or brackets.
  • Fig. 8 shows an alternative Butzenan inch
  • the threaded sockets 6 are outside the gap 20 between the individual additional armor plates 1, and the gap 20 between the additional armor plates 1 is completely filled with the clamping element 10 or 7, 8 or 16, 17, and thus hardly any ballistic weaknesses in Edge and Butzen Scheme has.
  • the pressure plate 15 projects beyond the outer edge of the additional armor plates 1 in order to be placed on the outside of the gap 20 between the additional armor plates 1 positioned threaded socket 6 and screwed down by means of screws 5 can.
  • Fig. 9 and Fig. 10 show a cross section GH Fig. 8 , where in Fig. 9 a homogeneous in the longitudinal direction of the gap clamping member 10 or 7, 8 or 16, 17 is used, and in Fig. 10 the clamping element 10 or 7, 8 or 16, 17 is divided into several, but at least two divided in the longitudinal direction of the intermediate space 20 items between the additional armor plates 1.
  • these individual elements 10 can also, as in Fig. 14 shown held in a thin-walled device 21.
  • Fig. 11 shows an embodiment of a welded on the base armor edge strip 2 or 12 or 13 or 14, wherein on both sides additional armor plates 1 are adjacent.
  • the skirting is here beveled with undercut shown, in addition to the traction in the clamping and a To ensure positive connection with the adjacent additional armor plate 1; but it can also be made straight and thus hold only non-positively.
  • Fig. 12 shows an exemplary embodiment of a welded on the base armor edge strip 2 or 12 or 13 or 14, which serves as the end of the surface to be protected with an additional armor 1, and limits only one additional armor plate 1. Again, it is shown as beveled, and as described above, can also be executed.
  • Fig. 13 shows an alternative embodiment of the edge strip 2 or 12 or 13 or 14, in which the additional armor plate 1 side either beveled or as shown here just limited, and additionally clamped with a resilient clamp 18 by means of the screw 19.
