Description

The present invention relates to a device for the supply of

  ammunition, from a magazine located below a platform rotating about a vertical axis, a gun pointable in height and arranged on the platform, which device has a hoist and a horizontally orientable ammunition receiver, connecting at its upper end, the inclination axis of the receiver being at the same height as the axis of orientation at the site of the gun, the device having for each transport path a mobile transverse conveyor with the barrel around the axis of orientation in site, which carrier transmits the munition from the supply position in the extension of the axis of the core of the barrel, where it is pushed by means of a presentation device in the barrel tube, in particular

for armored vehicles.

  A device of this type is essentially known, for example from German Federal Republic Patent No. 634,474. In this device for feeding ammunition

  provided for two guns, four projectiles are transported simultaneously

  the two guns to the oscillating loaders acting as transverse conveyors and then they are transmitted to the two pairs of loaders each associated with a gun, the loaders being

  placed alternately and in opposition in the loading position.

  With this old realization, two projectiles can be pre-

  trimmed simultaneously for each gun and be loaded one after

  the other. This known device, however, is suitable only for food

  munitions of the same type. In case of implementation in usually changing combat situations, this device is not to be used, because, in this case, projectiles effects

  various are needed (eg explosive or incendiary effects).

  In addition, in this old assembly, the loading process is

  manual, the device being served by a gunner.

  Thanks to the patent application available to the public of the Federal Republic of Germany 25 01 426, there is also known an automatic loading device for a large caliber weapon, including an armored vehicle, with stores placed on the market. and other weapon and tilting in azimuth and in

  site with it, which stores constitute a unit of

  a loading trolley behind the weapon and

  each store. Each loading trolley is movable both parallel to the axis of the barrel of the weapon and perpendicular to this direction and it has a built-in stuffer. The two magazines in which the ammunition is installed parallel to the axis of the tube can receive different types of ammunition, but they must be supplied by hand from the rear using the loading trolley. This not only causes a high loss of time which leads to a significant drop in the rate of fire, but also represents a high risk for the crew. In addition, because of

  the positioning of the projectiles and their transverse displacement.

  sal in receiving position, it is necessary to have a wide profile for stores located on both sides of the weapon and linked to it. In vehicles carrying weapons, there is a need to make these vehicles as small as possible

  in height and width to have fewer impact surfaces.

  This requirement is not sufficiently satisfied in the realization

  known, because of the mounting width of the bearers of weapons.

  An object of the invention is therefore, in a

  the type indicated at the beginning, to take measures

  without a noticeable increase in congestion, the choice of food with ammunition of different types to be able to fight

  different goals, ensuring an uninterrupted pace of fire.

  The means of achieving this object according to the invention is that it is provided from the mobile ammunition magazine

  freely in relation to the rotating platform, two paths of trans-

  separate ports, each with a freight elevator, a

  tubular ammunition and a tubular loading trolley, the

  load being placed laterally symmetrically with respect to the pointing axis in the direction as well as in the vertical plane of the gun pointing axis in height, and ammunition receivers having their axis of inclination in the extension of the aiming axis in height of the barrel, the goods lifts being designed for the reception

  of a projectile, in that, in putre, each loading trolley

  its longitudinal axis in the horizontal plane of the axis of the barrel tube and moves on slides parallel to this plane in

  the longitudinal and transverse direction, with a known unit of extrac-

  munitions and charging, and in that the two loading carriages are operated transversely in a known manner, alternately and opposite way. In one embodiment of the invention, the two longitudinal rails are symmetrically parallel to the axis of the barrel tube and the two transverse slides are

  parallel to the barrel orientation axis.

  Another embodiment of the invention is characterized in that the two longitudinal guides are oriented symmetrically obliquely with respect to the axis of the barrel tube, the two transverse slides being placed in an arc of

  circle vis-à-vis the pointing axis in height of the barrel.

  In another embodiment of the invention,

  the two tubular loading carriages are placed with their slides and drive devices in a movable housing with the barrel around the pointing axis towards and from the axis.

  Other features and benefits of

  the invention will be better understood from reading the description which

  follow of an exemplary embodiment and with reference to the accompanying drawings in which:

  different transport systems and the longitudinal and trans-

  versales loading carriages being parallel to the axis of the tube and to the axis of pointing gun height; and - Figure 2 shows a top view of a disposition corresponding to that of Figure 1, wherein the longitudinal rails of the two loading carriages are oblique to the axis of the barrel tube and in which the slides

  transverse are in an arc.

  On a platform 2 rotating in a shielded ceiling 1 (vehicle or concrete shelter) around a vertical axis, a gun 3 has been positioned which is height-adjustable by means of lateral journals 4, 4 'in binoculars 5, 5 ', the barrel having in the drawing an angle of zero site. Below the platform 2 is fixed a crew station 6 whose vertical axis coincides with the pointing axis in the x-x direction of the barrel 3.

  In post 6 there is a shop in muni-

  7 freely movable with respect to this station and to the platform 2,

  in which projectiles are stored vertically.

  sin can be a round or tape magazine and is movable clockwise or in the opposite direction, so that the projectiles 8 can be moved one after the other in a position provided according to the type desired ammunition. In addition, there is arranged on the lower side of the platform, on either side and symmetrically with respect to the x-x axis, an ammunition hoist

  9, 9 'known per se, the longitudinal axis of which extends in the vertical plane

  tical of the axis y-y of barrel height orientation 3. For each load bearing 9, 9 ', there is provided in the rotating platform 2 a

  opening 11, 11 'closable by a hinged lid 10, 10'.

  At the upper end of each freight elevator 9, 9 'is connected,

  above the revolving platform, a receiver of tubular

  align with the journals 4, 4 'and have a tilting axis

  in the extension of the axis y-y of the barrel 3. Each projectile prepared in the magazine 7 is taken out of it by a grapple located on the elevator 9, 9 ', it is moved upwards at

  through the opening 11, 11 ', released for a short time, from the platform

  form 2 and it is introduced into the ammunition receiver 12, 12 '.

  The highest position of the freight elevator is limited by a stop 14,

  For the reception of the projectile, it is provided with a centering as well as a fixation (both not shown). Then, the ammunition receiver in which the projectile is located is tilted using a tilting device (not shown) from the position shown in dashed lines in FIG. 1 and is tilted about the axis yy, until it bears against an abutment (not shown) of the mobile housing 15 with the barrel 3, both around

  of the y-y axis around the x-x axis.

  In this transfer position, the longitudinal axis

  The receiver 12, 12 'is at the same height as the Z-Z axis of the tube 16. In the vertical supply position, the ammunition receiver also relies on a stop. In the housing 15 is, for each transport path, a tubular loading carriage 18, 18 'whose longitudinal axis is in the horizontal plane of the axis ZZ of the tube 16 and can be moved on slides 19 , 19 '

  and 20, 20 'parallel to this plane, in the longitudinal and trans-

  versal. In addition, each loading trolley has a carrier

As soon as the loading carriage has reached its loading position in which it bears against an abutment not shown on the breech 17 of the barrel 3, and that it is, with the driven projectile, in a position coaxial with respect to the axis ZZ of the tube 16, the integrated introduction unit 21, 21 'moves the projectilesafter the projectile holders were released on the carriages, in the breech of the barrel. Then, the introduction unit and the loading carriage return to the starting position, after

  which the socket of the fired projectile is ejected and reaches the outside.

  The ammunition receivers 12, 12 'lying one behind the other in each transport path, with their longitudinal axes in the horizontal plane of the axis ZZ of the tube 16, and the loading carriages 18, 18' with their longitudinal rails 19, 19 'may be arranged either in parallel or, as shown in FIG. 23, obliquely with respect to the axis ZZ of the tube 16. In the embodiment of FIG. 2, this is for the device ammunition introduction of a very narrow assembly. The receivers 12, 12 'must execute during their inclination movements,

  in addition to the horizontal rotation movement, an additional movement

  in the space and the transverse slides 20, 20 'for the

  carriages 18, 18 'must have an arcuate shape.

  All phases of movement can be

  controlled from a console in crew station 6.

  The drive devices, both for automatic transport and

  ammunition tick that for the automatic transfer of ammunition from the magazine to the breech of the barrel and the fixings of the projectile, are considered as known and are not directly related to the invention, so that their assembly and their mode of operation

  are not described in detail here.

  The advantages obtained with the invention by

  known provisions consist in particular in the clutter

  the barrel for the supply of ammunition, so that the implementation of the device is substantially facilitated with limited space conditions. In addition, this device allows a

  rapid fire rate, kept longer, because the power supply

  ammunition between the store and the loading position is

continuously produced.

  Of course, various modifications can be made by those skilled in the art to the devices or methods which have just been described as nonlimited examples.
