Definitions

  • the invention relates to the remote control of infantry weapons in particular those of machine guns.
  • the machine gun is held in a device, for example in a carriage, which contains a safety actuator for securing or unlocking the machine gun and a trigger actuator for firing the machine gun.
  • DE 102 04 292 A1 also relates to a device for increasing the safety of the operation of a machine gun with a second in the path of the Abfeuerermagneten to provide increased safety in errors in the firing circuit and to avoid accidental firing.
  • the invention has as its object to ensure compliance with the operating sequence both in case of failure and under extreme environmental or operating conditions with simple means.
  • the invention is based on the idea, once by means of an adaptable magnetic carrier frame at the rear end or to the bottom piece, preferably instead of the shoulder support of a machine gun made interchangeable and ideally mount in these a trigger magnet and a safety magnet. Both magnets ensure that the safe operating state is achieved in the event of a fault. In addition, there must be no entry into the operating sequence if there is an error.
  • the pull-in winding of the securing magnet is supplied via a capacitive energy store, referred to hereafter as a smoothing capacitor, which supplies the energy for the duration of the tightening, that is to say the duration of the switched-on take-up winding.
  • the smoothing capacitor significantly reduces the supply current for the benefit of the lead design and provides a large winding current for the benefit of the pull winding design.
  • the smoothing capacitor is charged to a specified voltage via a voltage converter in order to be able to provide a constant energy, for the benefit of magnetic design, independently of a vehicle electrical system voltage (17.5 V to 32 V). With defined energy supply at the highest possible charging voltage, the magnet can be small and easily interpreted.
  • the previous solenoid is replaced by a reversing solenoid, allowing for single-fire shooting and rapid single-fire shooting.
  • the energy for the stroke and return stroke supplies the described smoothing capacitor.
  • the double use of the smoothing capacitor saves space and mass.
  • the starting current in the trigger magnet is reduced to a holding current as soon as its armature is in the working position.
  • the holding current is sufficient to hold the anchor in the working position.
  • the Stromkonstanter significantly reduces the supply current, especially in the case of continuous fire or intermittent firing (Dauerfeuersch devisrhythmen) to the advantage of the cable layout.
  • Fig. 1 shows in general form the operating sequence of an automatic machine gun (MG), wherein in the case of an error, an automatic sequence is initiated.
  • MG automatic machine gun
  • F1 power interruption, emergency stop, undervoltage
  • sensor-detected errors F2 sensor-detected errors
  • the machine gun is transferred to the secured state (MG OFF and secured).
  • sensor-detected errors which are derived from the function monitoring FÜ according to defense device standard VG 95 287 and include the mechanical assemblies
  • the machine gun is transferred to the secured state (MG fault and secured) and communicated the error by the integrated test system IPS the operator.
  • the energies for the stroke from the working to the rest position are taken from both magnets of the respective integrated spring. The tensioning of these springs takes place during the working stroke.
  • Fig. 2 shows the side view from the right of the rear part of a machine gun without shoulder rest. Parts of the machine gun 11.n are for better understanding in Fig. 2 featuring texts.
  • the magnet carrier frame 6 is preferably suspended without tools.
  • the magnetic frame 6 carries the trigger magnet 1, the securing magnet 7 and the mechanism for transmitting power between the magnet and the machine gun.
  • the armature shaft of the trigger magnet 1 ends preferably in a joint 1.2.
  • a guided in the frame 6 preferably U-shaped, the handle on the left side evasive, rod 3 is mounted.
  • the front in the direction of weft end of the rod 3 lays like a finger in front of the trigger.
  • the front end of the rod 3 is slidably or preferably provided with a roller 3.1, so that it slides or rolls on the trigger during the lifting movement.
  • the magnet 1 preferably has a connector 1.1, which is permanently installed as shown or mounted on a cable tail.
  • the armature shaft terminates in a connection to which the elastic rod 3 is attached. Due to space constraints, it may be necessary that the armature of the trigger magnet 1 and the securing magnet 7 is extended by the bearing plate B 1.3 or 7.3 and provided with a handle for manual operation of the trigger or the weapon safety.
  • Fig. 3 shows the bolt, with the frame 6 is staked on the machine gun.
  • the arrangement of the two magnets 1 and 7 is determined by the external space conditions, a displacement of the magnets 1 and 7 to each other or one above the other is possible and permissible.
  • Fig. 4 shows the side view from the left of the machine gun.
  • the armature shaft of the securing magnet 7 preferably ends in a joint 7.2. From this, the magnetic force is transmitted by means of a rod 8 via a further joint 9.1 to a rocker 9.
  • the rocker 9 is mounted in the frame 6. About the bearing point 9.2, the rotational movement is transmitted to safety wing die 9.3.
  • the frictional connection between the die 9.3 and the safety wing takes place.
  • the shape of the die 9.3 satisfies the secure adhesion.
  • the armature shaft ends in a connection to which a rack is attached.
  • the lifting movement of the securing magnet 7 is converted by means of the rack into a rotational movement of the rocker 9.
  • the joint can be performed 9.1 as a slot in which the extended armature shaft is staked.
  • Fig. 5 shows the side view from the right on the back of another machine gun.
  • the illustrated construction is equivalent to that in FIG Fig. 2 to Fig. 4 shown.
  • the magnet carrier frame 6 is preferably mounted without tools on the bayonet coupling of the shoulder support and locked with a bayonet nut 10.
  • the magnetic frame 6 carries the trigger magnet 1, the securing magnet 7 and the mechanism for transmitting power between the magnet and the machine gun.
  • the armature shaft of the trigger magnet 1 ends preferably in a joint 1.2.
  • the guided in the frame 6 is preferably U-shaped, the handle on the left evasive, rod 3 hooked.
  • the front end of the rod 3 is slidably or preferably provided with a roller 3.1, so that it slides or rolls on the trigger during the lifting movement.
  • the trigger magnet 1 also here preferably has a connector 1.1, which is permanently installed as shown or mounted on a cable tail. The same applies to the plug 7.1 of the securing magnet 7.
  • the arrangement of the magnets 1 and 7 is determined by the external space, a shift both to each other or one above the other is possible and permissible.
  • the armature shaft of the securing magnet 7 preferably terminates in the joint 7.2.
  • the magnetic force is transmitted by means of a run in the frame 6 contour pin 5 on the safety slide.
  • the frictional connection between the contour pin 5 and the safety slide takes place.
  • the lifting movement of the securing magnet 7 is converted by the contour pin 5 in a transverse movement, by which the safety slide between the positions secured and unlocked changes.
  • Tightening windings are supplied with voltage for the duration of the lifting movement ( ⁇ 100 ms), holding windings for the duration of holding in the working position.
  • the armature of the securing magnet 7 is moved from the rest position to the working position when the contactor switches on the safety switch on the operating device. When switching off the anchor of the securing magnet 7 falls back by the minimum waiting time delayed in the rest position.
  • the minimum waiting time determined from the buffer capacitor holding winding arrangement is greater than the return stroke movement time of the tightening magnet armature plus a reserve time> 1 / cadence. In this way, the operating order is according to Fig. 1 respected.
  • the lifting movement of the safety magnet is prevented when the armature of the trigger magnet, detected by sensors, is not in the basic position.
  • a first monitor checks the buffer capacitor 1 holding coil 1 arrangement of the fuse magnet.
  • a second monitoring checks the buffer capacitor holding winding arrangement of the securing magnet 7. The monitors check alternately, whereby the current operation must not be interrupted.
  • the - thus sensory detected - failure of one of the two arrangements transfers the machine gun in the secured state in compliance with the operating sequence according to Fig. 1 , The detected fault is communicated to the user by the integrated test system.
  • the single fire is initiated when the shooter presses the fire button on the directional handle.
  • the attraction winding of the trigger magnet 1 is supplied with voltage for the duration of the lifting movement and a holding time.
  • retraction winding is supplied with voltage for the duration of the return stroke.
  • these supply times will more or less overlap.
  • the energy of a smoothing capacitor is used, which is designed for the fast process.
  • the continuous fire is also initiated by pressing the fire button on the directional grip.
  • the pull-in winding of the trigger magnet 1 is tensioned until the shooter releases the fire button.
  • the trigger magnet 1 carries out the lifting operation with the energy of the buffer capacitor and is designed such that it can be held in the firing position with the subsequently lower current.
  • the trigger magnet returns to its home position via its internal spring.
  • the return stroke can be carried out quickly via a second buffer capacitor connected only to the pull-back winding. This arrangement is used for fast single fire.
  • capacitors instead of capacitors, it is also possible to use other energy stores which can apply the same power levels required by the system.
  • the capacitors can be composed of several and different types of capacitors depending on space and cost.
