Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention provides a structure in which a plurality of cylindrical containers, each adapted to receive and supply one ammunition, are arranged parallel to each other with respect to the bore axis of the barrel of a firearm. and is circulated at the rear of the firearm in an endless path located in mutually upper and lower horizontal planes perpendicular to the bore axis, and both end surfaces of the cylindrical container are guided into guide rails. into another guide rail fixed in the ammunition magazine via two guide pins connected to the chain via a circumferential pin and fixed to each said container outside the circulation path of the circumferential pin. The guide is arranged so that the container always has a constant attitude, and the second guide rail, which is one of the other guide rails, is arranged in a section outside the curved area of the endless path. The present invention relates to an ammunition magazine for a firearm mounted on an armored tower, in particular of an armored vehicle, which comprises a partially curved section defined by a curved section.

[Background Art] Certain known configurations of this format (German Official Bulletin)
According to No. 1938681), both guide pins are at equal distances from the swivel pin and are arranged at the periphery of the container on a chord line that is an extension of the horizontal guide rail section. Therefore, the guide rail passes through two tracks in the curve. Therefore, points are required, and not only is it impossible to expect uniform guidance without vibration and disturbance, but also, in the case of an armored vehicle traveling on uneven terrain, the conditions for stable mooring of ammunition cannot be satisfied due to oscillation.

Moreover, both guide pins cannot exert a sufficiently large counteraction when an impact occurs when they synchronously pass through a curved apex of both guide rails.

With these drawbacks of the prior art in mind, it is an object of the present invention to ensure that the ammunition holding element is guided invariably and with uniform reliability over the entire circulation path, even when traveling over highly uneven terrain. The object of the present invention is to improve an ammunition magazine of the type mentioned at the beginning of this section so that the guide chain can operate without failure.

[Disclosure of the invention] According to the invention, this problem is achieved by arranging the two guide pins at unequal distances from each other from the rotation pin,
a first guide rail that guides a first guide pin disposed at a relatively short distance from the surrounding pins, has an endless path having a curved portion, and holds the container in a constant posture at all times; , a second guide pin disposed at a relatively remote distance from the swivel pin is guided, and the second guide pin is guided only when the first guide pin is guided at or near the apex of the curved portion. This problem is solved by comprising only the partially curved portions to which the two guide pins are guided, and each having a second guide rail having an entry flare 17 at the entrance of the partially curved portions.

According to the invention, only the first guide pin located relatively close to the swivel pin receives constant guidance over the entire closed endless path in the first guide rail assigned to it. Therefore, no points are required on the guide rail, and a uniform guiding effect occurs as a whole. In cooperation with the swivel pin connecting the containers to the conveyor chain, the single guidance described above via the first guide pin in the first guide rail is sufficient, at least for a horizontal path. However, in the region of the bends of the endless path, a further second guide rail is required. The second guide rail is such that the position of the second guide pin guided by it is at a relatively large distance from the swivel pin.

The spatial arrangement of this second guide rail is as follows. That is, while the first guide pin guided by the first guide rail passes at or near the apex of the curved part of the endless path along its perpendicular line, the guide pin receives an undesired collision or impact. In this case, the above-mentioned impact is absorbed by the second guide pin which is passing through another second guide rail at this point. The contour of the second guide rail consists of a partial curve.

The second guide pin is not guided in the horizontal travel range and therefore runs without load. The second guide rail has flared portions at both ends so that the second guide pin can easily enter.

In this case, it is even more advantageous if the first guide pin, which is located relatively close to the swivel pin, is as far out from the container as possible, which is realized by way of example by a fixed arm. This leaves both ends of the container unobstructed and allows for unimpeded loading of the firearm with fresh ammunition and replenishment of the container with fresh ammunition.

[Example] Next, an example of the present invention will be further described with reference to the drawings.

Figures 1 and 2 show the rear of armored tower 1.
can rotate about a fixed axis A-A. A cannon 2 is supported in the armored tower 1, and can be rotated in the height direction about a trunnion axis B-B to determine its aim. Loading the ammunition 3 into the cannon 2 is done by using the loading guide device 4.
The magazine 8 is circulated through a cylindrical container 5 via a pair of endless sprocket chains 6 perpendicular to the bore axis 7 of the cannon 2.

The container 5 into which the ammunition 3 is loaded is located in the lower running zone of the endless sprocket chain 6 so as to be colinear with the bore axis 7 of the cannon 2.

For this purpose, the cannon 2 is swung to the "0" altitude position. The bulkhead 9 separating the magazine 8 from the space of the rest of the armored tower 1 is provided with a through hole on the running strip of the magazine. Circulating the magazine 8 along the sprocket chain 6 can be accomplished by an electric motor 10 or, if necessary, manually.

FIG. 3 shows a state in which the sprocket chain 6 is guided around two sprockets 11,
Either sprocket 11 is a drive sprocket. The sprocket chain 6 is guided by a guide rail (not shown). Pin 12 goes around the special chain link of sprocket chain 6.
The container 5 is supported by the container 5.

In order to prevent the container 5 from swinging freely at the circumferential pin 12, an arm 13 projecting slightly outward is fixed to the container 5. Arm 13 carries a first guide pin 14 .

The first guide pin 14 engages laterally into the magazine 8 .

The first guide rail 5 forms a closed endless path,
This endless path is located at the following position with respect to the sprocket chain 6. That is, since the arm 13 has the same spatial angle at all positions, the container 5 also maintains the same attitude at all times. The container 5 is therefore guided in a sufficiently reliable and even manner in the horizontal section. That is, the swivel pin 12 is moved in the traction direction by the tensioned sprocket chain 6 and also by the first guide pin 1.
4 is held at right angles to the chain 6 by the horizontal flange of the U-section of the first guide rail 15. This must also be maintained in the curved region of the closed endless sprocket chain 6 and the first guide rail 15.

However, the guiding function is weakened in the vertical direction and is weakest at the apex of the curved area (see Figure 3). Therefore, if a certain degree of selection is unavoidable, if a load is applied to the container 5 due to a lateral collision or impact when the container 5 is traveling vertically, the first guide pin will be able to absorb that load. It cannot be absorbed. To solve this problem, a second guide pin 16 is provided in the container 5 at a sufficient distance from the rotation pin 12. That is, when the first guide pin 14 reaches the curved area of the first guide rail 15, the second guide pin 16 moves to the second guide rail 18 fixed to the magazine 8.
The vehicle then enters through the entry flare section 17.

Therefore, over the curved area, the rotation pin 12, the first guide pin 14, and the second guide pin 16
Point support is achieved. When the first guide pin 14 is at point C in the first guide rail 15, the second guide pin 16 has reached point D, and the vertical impact at point C causes the containers 5 to be firmly attached to each other. The effective action at the three connected points is converted into a horizontal load at point D. This load is reliably compensated for by the second guide rail 18. Since the entry flare portions 17 of the second guide rail 18 are provided at both ends thereof, the circulation direction may be either. In FIG. 4, the staggered arrangement of the chain 6 and the first guide rail 15 with respect to the longitudinal axis of the container 5 is illustrated in a perspective view.
The loading of the ammunition 3 into the cannon 2 via the slope 4 is carried out by pushing the pushing piece 33 through a guide roller driven by a pair of rigid chains 34 which are recessed and manually driven by an electric motor 35 or if necessary. It is done by extrusion.
