Abstract

The complete gun assembly, the ammunition magazine and the crew seats form a unit which is connected by trunnion pins to the rotating inner ring of the tilting bearing. The elevation axis formed by the trunnion pins, when viewing in the direction of firing, is situated in front of or behind the tilting bearings. The tubes of the aiming devices and optical systems pass through the rotting joint of the gun cradle, bearing housings as well as the inner ring of the tilting bearing, and through the tilting bearings proper. The outlet openings for the tubes of aiming and observation appts. may be arranged in the upper part of the gun rotating joint in the turret or between the rotating joint and the top cover of the turret.

Storage of a barrel weapon in the tower of

armored vehicles

The lirfindung relates to a storage of a barrel weapon in a rotatable tower of armored vehicles, the barrel with barrel cradle, the dome, the ammunition magazine and the seats for the crew form a structural unit and are connected to the tilting bearing via trunnions.

In an older version of this type, which does not belong to the state of the art , the cradle carrying the weapon barrel is pivotably arranged with its two-sided trunnions in the inner ring of the canting bearing, which is fixed with its outer ring in the tower dome, which is rotatable about the core axis of the weapon barrel. On the cradle, namely on the panel closing off the vehicle interior or crew room in the area of the tilting bearing to the outside , there is a bearing for a guide sleeve on the tower side above the weapon barrel, which dome upwards out of the tower through an opening in the ceiling of the tower dome protrudes, and in the sighting devices or optics, possibly also a holder for light weapons, are passed , the movement of which takes place synchronously with the movement of the weapon barrel. The ring opening located between the movable guide sleeve and the edge of the hole in the tower dome ceiling is closed off from the vehicle interior or crew compartment by an elastic seal.

The arrangement of the opening in the ceiling of the tower dome not only requires constant monitoring of the seal, but also poses a risk when the vehicle is in use

the operating team and the devices located in the tower, dn dio bullets or splinters penetrating through the seal cause injuries to the operators and the Can destroy devices or facilities.

The invention is based on the object of the storage at a To improve barrel weapon of the type mentioned so that for the sighting devices or optics protruding from the vehicle only a comparatively small opening in the vehicle interior or crew compartment to the outside bounding wall and thus only a slight weakening of the armor protection with good Sealing option is available.

This object is achieved according to the invention in that the cradle carrying the gun with its two-sided trunnions attached to the rotatable inner ring of the tilting bearing, extending in the direction of the core axis of the weapon barrel is supported, which are arranged diametrically such that the elevation axis formed by the trunnions - in

A preferred embodiment of the invention is that the bearing eyes for the trunnions of the cradle on the The side facing the tube mouth on the rotatable inner ring of the pre-bent bearing are arranged.

An exemplary embodiment of the invention is shown in the drawing shown schematically and is described in more detail below.

Show it

1 shows a longitudinal section through the turn of an armored vehicle, the barrel weapon being shown partially and the barrel cradle broken away,

FIG. 2 shows a section along the line AD in FIG.

In a trough of an armored vehicle, which is partially shown, a turn 1 is mounted by means of a turntable 2 and can be moved by a drive device located in the vehicle trough about its vertical axis, which is at the same time the directional axis XX of the barrel weapon. The tower 1 comprises a herausragehden from the vehicle roof 3 tower dome k with .einem after anschlieseenden below basket 5 · In the exemplary embodiment the tower dome k of a blanket 6 with anschilessender inclined and curved side wall 7 is formed. In the area where the ceiling 6 merges into an inclined front plate 8, there is a canting bearing 91 in the tower dome 4, the outer ring IO of which is arranged in the tower dome in a rotationally fixed manner and the rotatable inner ring 11 of which surrounds the drilling weapon and two diametrically in the direction of the core axis of the weapon barrel 12 arranged bearing eyes 13, 13 * has.

The weapon barrel 12 is held in a known manner in a barrel cradle ld which, by means of two-sided trunnions 15, 15 'forming the elevation axis TT of the barrel weapon, can be pivoted in the two bearing eyes 13 »13' of the inner ring 11 of the canting bearing 9, which is rotatable about the core axis of the weapon barrel 12 is arranged. The cradle Ik is designed as a diaphragm l6 towards the mouth of the weapon barrel and has a spherical part 17 in the area of the tilting bearing 9, which is located above and below the elevation axis YY between the two bearing eyes 13, 13 * and the rotatable inner ring 11 of the tilting bearing 9 , unspecified openings closes. .

409881/0703

The diaphragm l6 has an upper conically widened part 18, which merges into a spherical part 17 in the area of the tilting bearing 9. Furthermore, the diaphragm has a lower shell-shaped Part l8 ·, which in the area of the tilt bearing 9 also has a spherical section 19 has. With these spherical sections it is ensured that the rotating and swiveling movements of the Weapon in the area of their storage any gaps that may arise are covered bulletproof.

Firmly connected to the rear part of the cradle Ik and protruding into the tower is a housing 20, which with its upper section 27 encloses the weapon (also in the return position when firing) and the lower section 28 of which is designed as an ammunition magazine, on which the seats on both sides 21, 21 * are appropriate for the team.

Also firmly connected to the cradle Xk , the tubes 23 and 2k of the optics or viewing means protrude from the upper part 18 of the panel 16.

Thus, the weapon barrel 12 with the cradle Ik _{1 form} the cover l6, the tubes 23 and 2k for the optics, etc., the cladding 27 and the ammunition magazine 28 with the seats 21, 21 'a movable structural unit, which via the two-sided trunnions 15, 15' is movable in the elevation direction, further through the tilting bearing 9 in the tilting direction and through the turntable 2 in the azimuth direction. These movements are initiated by suitable drives (cylinders or rotary drives). In the present exemplary embodiment, only the elevation drive 22 is shown with the driver designed as a meridional guide. However, it is also possible that the elevation drive is formed from lifting cylinders arranged on both sides of the housing 20 instead of the embodiment shown, the piston rods being articulated on the housing 20 and each pivotably mounted in the tower cage 5 about an axis.

Above the weapon barrel 12 there is an unspecified opening in the inner wall of the spherical part 17 of the diaphragm 16 through which the tubes 23 and 2k of the sighting means or

409881/0703 " ^k "

Optics are passed from the vehicle interior. These tubes 23 and 2k protrude through openings 25 »26 located in the upper part l8 of the diaphragm l6 or between this and the ceiling 6 of the tower dome k - thus outside the armored dome 4 - out of the system. In order to prevent foreign bodies from penetrating into these openings, these seals are provided in a known manner, which were previously unspecified.
