Description

8103675-s 2 rear part and the lifting device with the tubular cartridge receiver cover each other in the vertical projection, it is possible to approach the elevator shaft of the cannon and the lifting device to a position very close to the vertical axis of rotation of the platform arranged in the roof of the armored vehicle. Advantageous further developments of the invention appear from the dependent claims.

An embodiment of the invention is shown in the drawing and is described in more detail in the following. In the drawing, Fig. 1 shows a platform rotatably mounted in the roof of an armored vehicle with a cannon with a hoist. In the roof and the device according to the invention in side view, the lifting device being shown in two different positions and the platform being depicted in section; Fig. 2 shows a top view of Fig. 1, in which only the parts essential to the invention are shown and the platform is shown partially broken away; and Fig. 3 shows a representation corresponding to Fig. 2 with another magazine.

In the roof 1 of an armored vehicle, not shown in more detail, a horizontally rotatably mounted platform 3 is arranged by means of a ball bearing 2, on which a gun 4 with its gun pins 5 and 5 'and bearing sides 5 and 6' is mounted rigidly in elevation and is shown with zero elevation . Attached to the underside of this platform 3 are both a crew room 7 and a lifting device 8 for the transport of ammunition from the magazine to the cannon.

The vertical axis of the single compartment coincides with the axis of rotation xx of the platform 3, which is at the same time the axis of lateral yy alignment of the cannon. The lifting device consists of an outwardly and inwardly moving telescopic rod 9 with a pivotable device 10 on which a cartridge receiver 11 charge tube and has known gripping claws (not shown) for the cartridge, as well as an actuator 12. The inward and outward movements of the lifting device, as well as the oscillating movement of the cartridge receiver and the movements of the gripping claws and the actuator are controlled by a sequence wlline. I. . Above the loading point of the lifting device there is an opening 13 in the platform 3, through which the telescopic rod 9, including the pivotable device 10 and the cartridge receiver 11, can be moved back and forth, and which by means of a door 14 known per se for a short time open through the said sequence link. When the lifting device 8 moves upwards from the loading position to the loading position, the vertical movement is superimposed in the first phase of the pivoting movement (90 °) and continues in the second phase. In this case, the movements indicated by arrows merge into each other without time interruption. In the vertical projection, the lifting device 8 is in the loading position and below

Claims (2)

3 8103675-8 the movement upwards before the pivoting movement under the rear part 15 of the cannon 4. In this case, the cartridge receiver faces the axis of rotation x-x of the platform 3 and the telescopic rod 9 towards the pivot bearing 2Å. The elevation shaft z-z formed by the pins 5 and 5 'is arranged at the distance a from the axis y-y of the gun 4 for lateral alignment, which is at the same time the axis of rotation x-x of the platform 3 (Fig. 1). The arrangement becomes even more advantageous if the distance a is reduced even further down to zero. In the embodiment according to Figs. 1 and 2, there is a tape magazine in the crew compartment 7, which is arranged symmetrically with respect to the cannon-1 first line. V In Fig. 3, magazine drums 18 and 18 ', respectively, are placed to the right and left of the crew compartment 7, also symmetrically with respect to the extended core line of the gun barrel, each with one: round' support plate and in the present case eight cartridges. In order to load the lifting device, the drums must in this case perform rotational movements around their longitudinal axis (cf. the arrow in fig. 3). The part of the crew room 7 in which the lifting device 8 and the belt magazine 17 and the two magazine drums 18 and 18 "are located, respectively, is separated from the other remaining part by a gas-tight partition (not shown). A further advantage of the object of the invention lies in, that the complete lifting device with its components 9, 10, 11 and 12 only needs to leave the room protected from the weather and hostile activity under the platform 3 for a short time, and does not require any unlinking or support points or auxiliary components above the platform for the movement in and out or during charging. A device for the automatic feeding and loading of ammunition, which is suspended inside an armored vehicle, to a cannon, which is attached to the vehicle with roofing equipment; with a lifting device for the cartridges, whose telescopic rod in vertical projection is arranged below the rear of the cannon, characterized in that a pivoting device (10), which is connected to the telescopic rod (9) and comprises a cartridge receiver (11), which is arranged to grip the cartridges from the side, likewise, is arranged below the rear piece (15) of the cannon (4), except that it can protrude beyond the vertical projection of the cannon, after it has been pivoted to the loading position; that the cartridges, which are lifted up with the bottom in front, are arranged to be able to pivot into the back piece from below; and that the pivot axis of the pivot device (10) is arranged on the telescopic rod upward and downwardly movable part and close to the front. the end of the cartridge located in the pivoting device (10), whereby the cannon can be arranged with its back piece near the edge of the barrel, seen in horizontal projection. I '' Device according to claim 1, characterized in that the telescopic rod (9) and the cartridge receiver (11) are arranged relative to each other so that the cartridge receiver is closest to the axis of rotation (xx) of the barrel, and that the upper end of the cartridge receiver first moves upwards and then at the transition to the charging position turns outwards. 3; Device according to claim 1 or 2, characterized in that the magazine for the cartridges is designed either as a tape magazine (17) or as two drum magazines (18, 18 ') and is arranged symmetrically' in relation to the extension of the core axis of the cannon.
