Definitions

  • the invention relates to a device for attaching projectiles to barrel weapons, in particular self-propelled howitzers, consisting of a linearly guided piecing device acting on the floor of the projectile, a preloaded spring accumulator driving the latter and a triggering device acting on the piecing device and absorbing the spring force in the locked position.
  • the projectile When loading barrel weapons, the projectile is manually or mechanically brought into a position in front of the base of the weapon, in which it rests on a loading cradle and its axis is aligned with the core axis of the barrel. From this position, the projectile is accelerated into the tube by means of the piecer and locked in the tube.
  • the drive of the piecing must therefore give the projectile high acceleration over a comparatively short distance, which requires correspondingly high driving forces and their short-term release.
  • Spring drives e.g. B. proven motor-biased coil springs (EP-A-256 250). In the pretensioned position, the spring force is absorbed by a release device which retains the piecing device.
  • the invention is based on the object of proposing a triggering device for a device of the structure mentioned at the outset which, with a simple and space-saving structure and reliable function, can absorb large pretensioning forces with a comparatively small triggering force.
  • the release device has a fixedly mounted catch hook, which interacts via a flat active surface with a flat counter surface on the piecing, that the active surface and the counter surface are each a surface of a freely rotatable multi-surface element and in the locked position under one Angles of less than 90 degrees to the force vector of the spring accumulator run, and that the catch hook for triggering the piecer can be pivoted by means of a trigger drive acting transversely to this force vector.
  • the polyhedron arranged on the catch hook and on the ratchet which can be designed, for example, as a hexagon, act together in the blocking position over one of their flat surfaces which lie against one another. Due to the flat design of the active surface and the counter surface, the preload force is absorbed on an always precisely defined, comparatively large surface. Because the active surface and the counter surface extend in the locked position at an angle of less than 90 degrees to the force vector of the spring, a secure locking is provided.
  • the trigger drive acts transversely to the force vector of the spring on the catch hook and pulls this while rolling the two polyhedron into the release position, so that the polyhedron is released on the attachment and the biasing force of the spring can be effective suddenly and in full.
  • the release force to be applied by the release drive only needs to be a fraction of the preload force due to its course transverse to the force vector of the spring.
  • the catch hook engages again.
  • the active surface and the counter surface form an angle between 75 degrees and 90 degrees, preferably in the range between 80 and 85 degrees, in the locked position with the force vector of the spring accumulator.
  • the force vector of the trigger drive also forms an angle between 75 degrees and 105 degrees with the force vector of the spring accumulator, in particular it can also run at approximately the same angle as the active surface and the counter surface in the locked position.
  • the necessary triggering force of the trigger drive can be reduced to less than 1/15 of the pretensioning force.
  • the force vector of the trigger drive and the force vector of the spring accumulator expediently form a somewhat smaller angle than the latter with the active surface and the counter surface in the locked position.
  • a further advantageous embodiment is characterized in that the bearing axis of the polyhedron mounted on the catch hook is offset in the blocking position in relation to a line connecting the pivot axis of the catch hook and the bearing axis of the other polyhedron in the direction of the open side of the catch hook.
  • the two polyhedra are in the locked position in a kind of dead center position, so that the pretensioning force helps to keep the catch hook in the locked position and the polyhedron only has to be brought over the dead center position when triggered.
  • the trigger drive advantageously engages the catch hook via a pull rod.
  • the trigger drive can be designed, for example, as a short-stroke electromagnet, which acts on the pull rod via a lever linkage which may be translated.
  • the trigger drive engages the pull rod via a pin which is guided in an elongated hole extending in the longitudinal direction of the rod.
  • pull rod is locked in the locked position, for example a push bolt supporting its free end can be assigned to the pull rod.
  • This locking prevents untimely triggering, for example due to shocks during shooting, driving movements or the like.
  • the slide bolt must first be brought into an ineffective position. This can be done for example by an electric motor. Only then can the trigger drive pull the pull rod and thus swing out the catch hook in order to release the pretensioning force on the attachment.
  • the turret 1 of a tank can be seen, on the bottom 2 of which a partially ring-shaped magazine 3 with storeys 4 set vertically is arranged.
  • the weapon 5 is mounted on a cradle (not shown in any more detail) and can be raised in a vertical plane.
  • a loading device 6 is mounted, which can be pivoted about an axis 8 by means of a drive 7 and from an approximately vertical position in which a lock 4 'can be removed from the magazine 3 into a by means of a pivoting loading arm 9 shown loading position is pivotable. In this position, the projectile 4 ′ lying on a charging cradle 10 is in the attachment position in front of the base piece 11 or the breech 12 of the weapon 5.
  • a device for attaching the projectiles is arranged on the loading device 6, by means of which the projectile accelerates from position 4 'according to FIG. 1 via position 4' 'shown in dashed lines in FIG. 2 and in position 4' '' in the trains the weapon 5 is barred.
  • the attachment device has an attachment 17 (FIG. 2) which engages on the floor of the projectile.
  • the ratchet 17 is acted upon by the drive in the form of a spring accumulator which, in the exemplary embodiment shown, consists of two tension springs 18 arranged on both sides of the charging cradle 10, which are pretensioned in the position according to FIG. 1 and relaxed after the attachment (FIG. 2).
  • a tension drive 19 is assigned to the tension springs 18.
  • Fig. 3 shows the piecing 17, which runs in a guide 19 on the loading device 6.
  • the piecing has a nose 21 which extends downward in FIG. 3 and which cooperates with a fan hook 22 of the triggering device 20.
  • the catch hook 22 is pivotally mounted on a bolt 23, which in turn sits, for example, on the guide 19 and is acted upon by a leg spring 24 which is supported in a fixed manner and urges it into the locked position.
  • a polyhedron 27, 28 in the form of a hexagon is arranged on each mounted bolt 25, 26.
  • the hexagon 27 on the catch hook 22 forms a flat active surface 29 which interacts with a flat counter surface 30 on the hexagon.
  • the active surface 29 and the counter surface 30 bear against one another under pressure.
  • the surface pressure is determined by the biasing force of the tension springs 18.
  • the pretensioning force is received in the guide 19 via the catch hook 22.
  • the catch hook 22 and the nose 21 or the hexagon 27, 28 are assigned to one another such that the common plane 31 of the active surface 29 and the counter surface 30 with the force vector indicated in FIG. 3 by the arrow 32 encloses an angle of less than 90 degrees . Furthermore, the axis of rotation of the bearing pin 25 on the catch hook 22 is offset upwards from that of the bearing pin 26, as well as with respect to the pivot axis predetermined by the bolt 23 of the catch hook 22. This results in an over-dead center position in the blocked position, which prevents the piecer from being released prematurely.
  • the trigger device 20 has a trigger drive 33, e.g. an electromagnet, which acts on a bell crank 35 via a pull rod 34.
  • a trigger drive 33 e.g. an electromagnet
  • This in turn is mounted at 36 and engages via a bolt 37 fastened to it on a pull rod 38 which has an elongated hole 39 guiding the bolt 37.
  • the pull rod 38 the length of which is adjustable for adjustment purposes, is articulated to the catch hook 22.
  • the pull rod is moved in the direction of the force vector 45 by means of the trigger drive.
  • the force vector 45 forms an angle of less than 90 degrees with the force vector 32 of the tension springs 18. This angle is advantageously also somewhat smaller than that which the plane 31 of the active surface 29 and the counter surface 30 includes with the force vector 32.
  • a lock 40 is additionally provided for the pull rod 38 in order to maintain the blocking position even in the event of strong vibrations.
  • the lock 40 has a slide bolt 41 which engages in a fixed guide 42 and can be actuated by a servomotor 43.
  • the slide bolt 41 has a recess 44, into which the pull rod 38 can slide after the slide bolt 41 has been moved in the direction of the arrow 46 during the triggering process.
  • the operation of the trigger device 20 is as follows.
  • the release device 20 In the attachment position shown in FIG. 1, the release device 20 is in the locked position according to FIG. 3.
  • the tension springs 18 on both sides of the charging cradle 10 are pretensioned.
  • the servomotor 43 To trigger the piecing 17, the servomotor 43 is first excited, which moves the slide bolt 41 in the guide 42 in the direction of the arrow (to the right in FIG. 3), so that the recess 44 comes to lie below the free end of the pull rod 38. Then the electromagnet forming the trigger drive 33 is excited, which pulls the pull rod 38 in the direction of the arrow indicated downward via the pull rod 34, the angle lever 35 and the bolt 37.
  • the rotatably mounted hexagon 27, 28 roll on each other so that the catch hook 22 pivots downward about the bolt 23 until the hexagon 28 is released on the nose 21 of the piecing 17 so that it is accelerated by the tension springs thus released and transfers the acceleration force over the floor to the floor.
  • the tension springs 18 are moved back into the pretension position by means of the tensioning drive 19.
  • the piecing device 17 is moved back into the starting position according to FIG. 3.
  • the pull rod 38 is pressed upward in the direction opposite the arrow by means of the release drive 33, the catch hook 22 being carried along until the hexagons 27, 28 come into contact. These then roll on each other again until the active surface 29 and the counter surface 30 lie against one another and the catch hook likewise engages.
  • the slot 39 required for the entry of the two hexagon is guaranteed. If the catch hook 22 is in the locked position according to FIG. 3, the servomotor 43 is actuated again and the slide bolt 41 is pulled into the locking position according to FIG. 3.
