Definitions

  • a linear supply of the ammunition is described in a gun barrel or cartridge chamber having a control link used for function control in the horizontal plane parallel to the path of a straight-to-leading closure of the closure weapon.
  • the drive link is integrated in a movable slide, which in turn is adjusted by a universal design drive.
  • a locking link is provided, which is preferably integrated together with the drive link in the movable slide.
  • this locking link can engage a bolt preferably a weapon side arranged locking ring. This bolt in turn then moves the locking ring.
  • a connecting rod or the like is forcibly guided through the scenes and the slide along these scenes. With this connecting rod, the shutter is moved back and forth.
  • shutter movements occur in a foreign drive regardless of the gas pressure in the gun barrel, in the case of Anzündversagers (after supply of the ignition does not burn the propellant charge in the cartridge) or retarded (here the propellant burns off with a significant delay) opening the shutter must be prevented ,
  • the gas pressure or the weapon barrel itself is usually detected as an indication of proper burnup. If this information is missing, a so-called quick stop must be triggered and the opening of the closure prevented.
  • the weapon is equipped with a rapid stop next to a sensor for detecting a recoil, which can be brought to stop a normally continuously moving chain part and thus to stop the movement of the shutter in an engaged relative to the chain part position.
  • a locking device responsive to the sensor controls the movement of the stop between the engaged position in which the chain member is stopped and a disengaged position in which the movement of the chain member is otherwise unobstructed.
  • the protection system comprises two links connected to the chain member, a main member and a safety member, and a trigger bar controlled by a solenoid and a recoil push rod.
  • the recoil burst is for releasing a recoil latch when the shot is broken, the trigger bar for placing the safety member in place when locking the weapon and releasing when the ammunition fired properly.
  • the trigger rod engages the main member, since the solenoid is turned off.
  • such an electrically controlled solenoid is undesirable in particular in safety devices of this type, since itself prone to failure.
  • a possible material breakage of the rods also makes the safety device not functionally reliable.
  • the entire unit is also structurally very complex.
  • the DE 32 18 550 C2 discloses a blocking device for a machine gun with a foreign-driven shutter drive. This is an energy resulting from the shot development for a shot control device for interrupting the external energy supply. In a non-broken shot and the absence of return movement, disengagement of a control cam of the device from a retracted position to a driving position is prevented while a shift lever is being transported by a disconnector cam to a position where the continuous restriction of the power supply is achieved.
  • the disadvantage of this solution is also the high design complexity and the associated weight.
  • a drive for a weapon with linear ammunition supply which is characterized in that the linear supply of a closure to the gun barrel or cartridge chamber is achieved by a straight guide groove in a drive kinematics.
  • a driver is guided, which is structurally connected to the closure.
  • the guide groove is surrounded by a circumferential positive guide (gate), which in turn interprets the necessary downtime of the shutter during locking, firing, unlocking in its forward position and the reload.
  • a drive means for the closure is performed as a drive means for the closure.
  • the drive transmission can be realized by casters, gears or the like, which are driven by a motor, etc.
  • the drive itself continues to run within the downtime of the weapon, while the shutter is off in the downtime or later reinstated.
  • a slider is integrated, which realizes a release of the driver from the closure.
  • a drive with quick stop means comprising at least one motor and two counter-rotating chains is known.
  • the chains are in turn over Sprockets out and have on the chains integrated drive cam.
  • JP 7 139 896 A a similar structure is removable.
  • the invention has the object to show a drive for feeding the weapon lock to the chamber, in which the closure is automatically disconnected from the drive, in particular in the case of Anzündversagers or retarder.
  • a drive with quick stop device is proposed with a chain to which at least two drive cam are mounted.
  • the chain is guided around at least two sprockets and is preferably arranged below the closure.
  • a carriage is mounted in a guide at the bottom of the closure / closure carrier, over the full width of which a groove extends.
  • the respective driving cam moves the shutter in the weft direction forward or after the shot to the rear.
  • the downtime of the shutter in the front end position are realized in that the, the closure forward transporting drive cam is moved out of the groove and moved to the other side of the weapon without closure to the rear.
  • the present invention is based on the idea to incorporate as drive two opposing chains.
  • the rotational movement of the foreign drive such as an electric motor, realized in a forward and backward movement of a closure / closure carrier.
  • the axes of the sprockets are preferably transverse to the weft direction and thereby preferably below the closure.
  • One of the chains conveys the closure to the front, the other to the rear.
  • the closure is carried forward by one of the two chains on the left side of the weapon. While the other chain takes the lock on the right side of the weapon backwards (or vice versa).
  • the shutter is separated in its front and rear position from the drive. This can be done by disconnecting driver cams of the drive from the closure. These drive cams engage in a preferred embodiment for moving the closure in a below the closure located transversely slidable to the weft carriage. In its left position the carriage is in operative engagement with the cam of one (left) chain and in its right position with the cam of the other (right) chain. In the downtime of the shutter, the drive cams each leave the carriage when this has taken its middle position. In this middle position, the slide and thus the closure of both chains are separated.
  • the carriage is moved by one of the follower control cam on the right chain in its middle position and thereby separated from the drive. In this position, the lock is locked, the cartridge is ignited, initiated a weapons return. By this (also the use of a gas pressure is possible), the carriage is moved to the left (other) weapons or closure side, from where the carriage can be taken by the left chain on the drive cam of this chain with backwards.
  • the closure is guided from the second chain to the rear position.
  • the carriage is moved by the control cam of the second chain back to its middle position or moved and separated for the rear waiting time of the shutter from the drive.
  • the carriage is pushed from one element, such as one feeder, to the other (right) side.
  • the drive cam of the first (right) chain now drives from below into the groove in the carriage and takes the closure back with forward.
  • the carriage will not move to the left due to the absence of the weapon return, but will remain in its middle position.
  • the lock can not be unlocked and can not be taken back.
  • Fig. 1 shows a representation of a shutter drive with two chains 6, seen right and left in the weft direction, for a foreign-powered machine gun (weapon).
  • a gun barrel 1 is mounted in a pipe lock 2 (here locking bush) in which a shutter 3 is locked in its forward position.
  • the shutter 3 can be moved on shutter guides 4 in the direction of the weapon barrel axis.
  • the drive takes place via a bevel gear 9 which rotates two pinion shafts 10.
  • the bevel gear 9 is (not shown in detail) driven by a motor or the like (directly or indirectly, by means of transmission) and sets the two chains 6 by means of the pinion shafts 10 and the two rear sprockets 5 in motion, so that they rotate in opposite directions.
  • the upper run of the chain 6 moves in the direction of firing, on the left side of the weapon it runs in the opposite direction.
  • Both chains 6 each have a driving cam 7 and a control cam. 8
  • Fig. 2 shows a carriage 11 which is mounted transversely to the firing direction displaceable on two guide pins at the bottom of the closure 3.
  • a groove 12 in which the drive cam 7 of the chains 6 engage to take the shutter 3 in the weft direction forward or backward.
  • the downtime of the shutter 3 in the front end position or position is realized in that the drive cam 7 of the right chain 6 out of the groove 12 of the carriage 11 moves down and the carriage 11 at the same time on its ramp 13 by the control cam 8 selbiger chain. 6 is moved to its middle position. This is the upper web of a gun housing fixed holder 14 in the groove 12, whereby the shutter 3 is positively connected in its forward position with the weapon housing becomes. In this position, the carriage 11 comes with neither the driving cam 7 of the right nor the left chain 6 for engagement.
  • a firing pin (not shown in detail) is triggered, whereby a shot is made.
  • a weapon return which can be used to move the carriage 11 in its left position.
  • an expanding gas pressure can also be used.
  • the lever 15 used for this function is to be regarded as exemplary.
  • This function could also be represented in a different way, such as using the gas pressure instead of the weapon return or with an intermediate buffer spring. The latter could better tolerate the different length of return of weapons.
  • the lever 15 in Fig. 3 is the weapon return by the cam 21 ( Fig. 2 ) of the tube lock 2 is rotated and moves with its wedge-shaped nose 16, the carriage 11 at its chamfer 20 (FIG. Fig. 4 ) in its left position.
  • Fig. 5 shows this position against the weft direction seen (with slight deviations of the correct position of the driving and control cam 7, 8).
  • a pawl 17 is pivotally mounted on the holder 14. The pawl 17 engages in the groove 12 of the carriage 11 and thereby holds the shutter 3 in its position.
  • the drive cam 7 of the left chain 6 then runs from below into the groove 12 of the carriage 11, wherein the pawl 17 is pushed out of the groove 12 and the shutter 3 can be moved against the weft direction in its rear position.
  • the driving cam 7 of the left chain 6 leaves the groove 12 of the carriage 11 while the control cam 8 of the same chain 6 moves the carriage back to its middle position.
  • a holder not shown in detail is provided, which connects the closure 3 in this position form-fitting manner with the weapon housing.
  • the carriage 11 remains in its middle position when it is at the front. Since in this position, the carriage 11 comes with neither the driving cam 7 of the right and the left chain 6 for engagement, no unlocking and no further transport of the shutter 3 in its rear position can be done.
  • two motors can be used as independent drives of the right and the left chain 6. This requires synchronization of the two motors and the slight aftertaste that the entire drive unit will become larger.
