SLEEVESUM STUB CATCHING DEVICE AND VEHICLE

Description

[0001] The present invention relates to a cartridge case stub catcher for the armament of a vehicle, in particular a main battle tank, and to a vehicle, in particular a main battle tank, with such a cartridge case stub catcher.

[0002] Main battle tanks are armed, usually with a smoothbore cannon. This armament is loaded with cartridge ammunition. According to internal operational knowledge, such cartridge ammunition consists of a partially combustible casing, a propellant charge, and a projectile. When the weapon is fired, a hollow cylindrical portion of the casing burns away, leaving only a so-called cartridge stub. This cartridge stub is ejected, expelled, or extracted from the weapon. Such a cartridge stub may have a metallic base and a firing tube welded to the base. The cartridge stub can be, for example, 300 millimeters long.

[0003] The aforementioned design and dimensions of the spent cartridge case can lead to handling problems, particularly when using an automatic loader for the weapon. These problems include, for example, damage to sensitive components of the main battle tank's turret during ejection of the spent cartridge case, or jamming of the cartridge case during weapon aiming movements. Furthermore, it is undesirable for the spent cartridge case to lie undefined under the turret in the hull of the main battle tank.

[0004] Furthermore, the spent cartridge cases cannot be visually inspected, manually sorted, and / or disposed of on an unmanned turret. Randomly erect cartridge cases can collide with the weapon's breechblock during firing. Loose cartridge cases can also become secondary projectiles if the main battle tank is carrying mines. This needs to be improved.

[0005] US Patent 2022 / 0299287 A1 describes a diverting device for diverting belt links of various types of ammunition, wherein the diverting device comprises at least one diverting surface, wherein the diverting surface is arranged on a subfloor and wherein the diverting device comprises at least one fastening element.

[0006] Against this background, one object of the present invention is to provide an improved cartridge case stub catching device for arming a vehicle, in particular a main battle tank.

[0007] Accordingly, the invention is a cartridge stub catching device according to claim 1.

[0008] The shape of the deflector plate ensures that the spent cartridge cases are directed towards the outer edge, away from the center of the cartridge case catcher and thus away from the weapon. This prevents the spent cartridge cases from colliding with the weapon, for example, during firing or aiming movements.

[0009] The armament or weapon is preferably a smoothbore cannon. Preferably, the vehicle is a main battle tank. However, this is not strictly necessary.

[0010] The vehicle can also be another type of armed vehicle. The cartridge case stub is part of a cartridge or round of ammunition used in a weapon. Such cartridge ammunition consists—as previously mentioned—of a casing, a propellant charge, and a projectile. When the weapon is fired, part of the casing burns away, leaving only the cartridge case stub. The cartridge case stub comprises a base and a primer tube protruding from the base. After firing, the cartridge case stub can be ejected, expelled, or extracted from the weapon. An automatic loader can be used for this purpose, which can also feed the cartridge ammunition into the weapon.

[0011] The phrase "shaped such that casing stubs impacting the discharge tray move towards the perimeter due to gravity" is understood in this context to mean, in particular, that the discharge tray can have any geometry, especially three-dimensional geometry, that enables or causes the casing stubs to roll, slide, or glide towards the perimeter due to gravity. This can be achieved, for example, by orienting or sloping the discharge tray at least partially at an angle to the perimeter, so that the casing stubs roll, slide, glide, or are conveyed towards the perimeter due to this partial inclination or sloping of the discharge tray. Accordingly, the "movement" of the casing stubs on the discharge tray can include, for example, rolling, sliding, or gliding of the casing stubs on the discharge tray.

[0012] A particularly preferred device is a cartridge case stub catching device for the armament of a vehicle, in particular a main battle tank, which has a deflecting base and a circumferential border that partially surrounds the deflecting base, wherein the deflecting base is oriented at least partially at an angle to the circumferential border, so that cartridge case stubs impacting the deflecting base move on the deflecting base in the direction of the circumferential border due to gravity.

[0013] Alternatively or in addition to the at least partially inclined orientation of the discharge tray relative to the perimeter, the discharge tray can also be shaped by means of a curvature or bulge such that casing stubs impacting the discharge tray move towards the perimeter due to gravity. In this case, the discharge tray can be at least partially concave or convex to guide or convey casing stubs impacting the discharge tray towards the perimeter. In particular, the discharge tray can be at least partially spherical. A "spherical cap" in this context refers specifically to a section of a sphere. The discharge tray can be a freeform surface, at least partially.In particular, the discharge base can have any three-dimensional geometry or contour suitable for guiding or conveying sleeve stubs impacting the discharge base towards the perimeter by force of gravity.

[0014] The deflector plate is preferably designed, by virtue of its at least partial inclination or slant, to guide or convey the cartridge case stubs to the surrounding enclosure. The deflector plate is particularly located within the enclosure. The enclosure preferably surrounds the deflector plate in a band-like or wall-like manner. In particular, the enclosure has a lower edge and an upper edge. The deflector plate is preferably connected to the enclosure at its lower edge. The enclosure preferably encloses or delimits an interior space of the cartridge case stub collection device in which the cartridge case stubs are collected or caught. In particular, the enclosure can be fence-like or grid-like. In this case, the interior space can be visible from outside the cartridge case stub collection device. The enclosure can also be referred to as a boundary or outer wall.

[0015] The phrase "section-wise" refers specifically to the fact that the rim encircles the discharge base. In this context, it is understood to mean, in particular, that the rim preferably does not completely encircle the discharge base. For example, the rim is open on one side of the cartridge case stub catcher. Specifically, the rim is open in the direction of the armament. In particular, the rim is provided only on three of the four sides of the discharge base. For example, the rim has two side walls and a rear wall arranged between the side walls, preferably without a front wall. Therefore, the rim is preferably open opposite the rear wall.

[0016] The drainage floor can have several floor sections, which may be arranged at different angles to the perimeter. It may also include a floor section, in particular a base floor section, that is not inclined to the perimeter. This latter floor section may, for example, be oriented perpendicular to the perimeter. Accordingly, "partially inclined" means, in particular, that parts or sections of the drainage floor may be inclined relative to the perimeter, while other parts or sections of the drainage floor are not inclined to the perimeter and may, for example, be oriented perpendicular to it. In particular, the drainage floor, and especially its floor sections, extends from the base floor section at an angle towards the lower edge of the perimeter. The base floor section is, in particular, arranged between the lower and upper edges of the perimeter.

[0017] The statement that the cartridge cases move on the discharge tray due to gravity means, in this context, that, for example, because the discharge tray is at least partially inclined or sloping, the weight of each cartridge case causes it to roll and / or slide along the tray, moving outwards towards the edge. "Outwards" here means away from the discharge tray towards the edge. No external energy is required to move the cartridge cases towards the edge. The cartridge cases can come to rest against the edge.

[0018] According to one embodiment, the drainage base is oriented at least partially at an angle to the perimeter.

[0019] The drainage base is thus – as explained previously – arranged or positioned, for example, with its base sections at an angle to the perimeter. However, this does not preclude the possibility that the drainage base may also be oriented at least partially at an angle to the perimeter. For example, the aforementioned base section could be oriented perpendicular to the perimeter.

[0020] According to another embodiment, the drainage base has a truncated pyramidal geometry, at least in sections.

[0021] In this context, a "truncated pyramid" is generally understood to be a polyhedron with a base, a top, and four lateral surfaces that connect the base and top. The truncated pyramid geometry of the drainage base results from the fact that several base sections of the drainage base are arranged at an angle to one another. The sectionally truncated pyramid geometry preferably has three base sections arranged in a truncated pyramid shape, with one side of the truncated pyramid geometry being open. This results in the sectionally constructed truncated pyramid. In particular, the base sections form three lateral surfaces of the truncated pyramid. Accordingly, the truncated pyramid is not fully formed, but only partially formed, so that the truncated pyramid has not four, but only three lateral surfaces in the form of the three base sections.Furthermore, the truncated pyramid has no base, but only a top surface, in particular in the form of the aforementioned base section. The drainage base is thus preferably open at the bottom. "Partially truncated pyramid-shaped" can therefore mean that the truncated pyramid-shaped geometry of the drainage base is partially incomplete and, for example, has only three, and not four, lateral surfaces in the form of the base sections. The base sections are particularly trapezoidal. The base sections can widen or broaden from the base section towards the perimeter. The base sections can be of different sizes, geometrically different shapes, and / or inclined at different angles relative to the perimeter. This can result in an asymmetrical or non-symmetrical structure of the truncated pyramid-shaped geometry of the drainage base.The truncated pyramidal geometry of the drainage base is therefore not regular, but preferably irregular. In contrast, a symmetrical truncated pyramid is understood to be a geometry in which all lateral surfaces are of the same size and / or uniformly shaped. The base sections are preferably flat. However, this is not mandatory. The base sections, or some of them, can also be curved or arched, in particular concave or convex. In this case, the base sections form a curved or arched geometry extending from the base section towards the perimeter. The drainage base can thus have a curved or arched geometry, in particular a curved or arched contour, at least in sections. A combination of flat and curved base sections can also be provided.

[0022] According to another embodiment, the perimeter has a first side wall, a second side wall and a rear wall arranged between the first side wall and the second side wall.

[0023] The discharge plate is oriented at an angle to the first side wall, the second side wall, and the rear wall. Sleeve stubs striking the discharge plate are thus guided to the first side wall, the second side wall, or the rear wall. The rear wall is oriented perpendicular to the side walls. The rear wall can be directly connected to the side walls. However, it is also possible for connecting walls to be provided between the rear wall and the side walls. In this case, an indirect connection between the rear wall and the side walls is provided via these connecting walls. Preferably, the discharge plate is connected to both the side walls and the rear wall.

[0024] According to a further embodiment, the first side wall and the rear wall are connected to each other by means of a first connecting wall oriented obliquely to the first side wall and obliquely to the rear wall, wherein the second side wall and the rear wall are connected to each other by means of a second connecting wall oriented obliquely to the second side wall and obliquely to the rear wall.

[0025] The drainage base is also arranged at an angle to the first connecting wall and to the second connecting wall. The drainage base is connected to the first side wall, the second side wall, the rear wall, the first connecting wall, and the second connecting wall.

[0026] According to another embodiment, the first side wall, the second side wall, the rear wall, the first connecting wall and / or the second connecting wall have openings.

[0027] The openings can be slot-shaped. These openings allow inspection of the spent casing stump catcher, enabling, for example, determination of how full it is of spent casing stubs. The first side wall, the second side wall, the back wall, the first connecting wall, and / or the second connecting wall can be fence-shaped or grid-shaped. The first side wall, the second side wall, the back wall, the first connecting wall, and the second connecting wall are preferably rigidly connected to one another.

[0028] According to another embodiment, the drainage base is oriented obliquely to the first side wall, obliquely to the second side wall and obliquely to the rear wall.

[0029] As mentioned previously, the drainage floor is preferably also oriented at an angle to the first connecting wall and at an angle to the second connecting wall.

[0030] According to a further embodiment, the drainage floor has a first floor section which is oriented at an angle to the first side wall, a second floor section which is oriented at an angle to the second side wall, and a third floor section which is oriented at an angle to the rear wall.

[0031] The first and second soil section inclination angles can be the same. In particular, the first and second soil sections can be inclined in opposite directions. For example, the first and second soil section inclination angles can each be between 40° and 70°. The third soil section inclination angle can be the same as the first and second soil section inclination angles. However, the third soil section inclination angle can also differ from the first and second soil section inclination angles. For example, the third soil section inclination angle can also be between 40° and 70°. The third soil section is positioned between the first and second soil sections. The third soil section can be positioned rotated by 90° relative to the first and second soil sections.The first floor section is connected to the first side wall, the second floor section is connected to the second side wall, and the third floor section is connected to the back wall. The first and third floor sections may also be connected to the first connecting wall. Furthermore, the second and third floor sections may also be connected to the second connecting wall.

[0032] According to another embodiment, the drainage base has a base base section which is positioned parallel to and spaced apart from a lower edge and an upper edge of the perimeter.

[0033] The base soil section is thus positioned between the lower and upper edges. The lower edge spans a plane or lies in a plane. Similarly, the upper edge also spans a plane or lies in a plane. The base soil section also spans a plane or lies in a plane. The plane of the base soil section is positioned between the plane of the lower edge and the plane of the upper edge. The first soil section is inclined at a first base soil section inclination angle relative to the base soil section or to the plane of the base soil section. The second soil section is accordingly inclined at a second base soil section inclination angle relative to the base soil section or to the plane of the base soil section. The first and second base soil section inclination angles can be, for example, 10° to 20°.The first and second base soil section inclination angles can be equal. The third soil section is inclined at a third base soil section inclination angle relative to the base soil section or to the plane of the base soil section. This third base soil section inclination angle can, for example, also be between 10° and 20°. Accordingly, the first, second, and third soil sections are also inclined at their respective base soil section inclination angles to the plane of the lower edge and the plane of the upper edge. The plane of the lower edge and the plane of the upper edge are parallel to each other and spaced apart.

[0034] According to another embodiment, the base floor section forms a plane to which the first floor section, the second floor section and the third floor section are each inclined at a base floor section inclination angle.

[0035] As mentioned previously, the base floor section inclination angles can be different or the same. In particular, the first base floor section inclination angle of the first floor section and the second base floor section inclination angle of the second floor section are the same. The first floor section and the second floor section are inclined in opposite directions. The third floor section is arranged between the first floor section and the second floor section, preferably positioned perpendicular to both. The base floor section may have a through-hole or opening for a slip ring or a hatch. The base floor section inclination angles and the floor section inclination angles are preferably different. The floor section inclination angles are preferably larger than the base floor section inclination angles.

[0036] According to another embodiment, the rim has catching elements that point obliquely towards the drainage floor.

[0037] In particular, the retaining elements are provided at the upper edge of the perimeter. The retaining elements project into the interior of the shell casing stub retainer, which is enclosed or bounded by the perimeter. The retaining elements are inclined at a specific angle relative to the perimeter, especially to the first side wall, the second side wall, the rear wall, the first connecting wall, and / or the second connecting wall. The angle of inclination is preferably less than 90°. With the aid of the retaining elements, shell casing stubs sliding towards the perimeter are either tipped over or fixed in such a way that they cannot be ejected from the shell casing stub retainer, for example, if the vehicle is struck by a mine. The same applies to shell casing stubs that have already tipped over and come to rest beneath the retaining elements.

[0038] According to another embodiment, each trapping element has a triangular geometry, with one apex of the triangular geometry pointing towards the drainage base.

[0039] In particular, the locking elements are tooth-shaped. They can therefore also be referred to as locking teeth. However, the locking elements can also be tubular. They can be manufactured by cutting a jagged notch along the upper edge of the frame and folding it inwards. The locking elements can be provided along the entire upper edge of the frame. Furthermore, the upper edge can also be only partially fitted with locking elements. For example, a section of the upper edge on one of the side walls can be provided without locking elements.

[0040] According to another embodiment, the discharge base has ball rollers.

[0041] The discharge tray can be completely covered with ball rollers. Alternatively, it can be only partially covered with ball rollers. For example, ball rollers are provided on the first, second, and / or third tray section. The ball rollers facilitate the transport of the casing stubs along the tray sections towards the edge.

[0042] According to a further embodiment, the sleeve stub arresting device has steps for entering the sleeve stub arresting device and / or recesses for at least partially passing torsion bars of a track drive of the vehicle through the sleeve stub arresting device.

[0043] For example, a mounting rib projecting into the interior of the cartridge case stub retrieval device is molded onto the first floor section, and the steps are attached to this rib. The number of steps is arbitrary; for example, two steps are provided. Using the steps, a crew member can enter the cartridge case stub retrieval device and, for example, remove cartridge cases from it. The steps also prevent the crew member from stepping on the ball rollers. The steps can also be referred to as treads. The steps can be arranged at different heights, so that they can be arranged in a stair-like or stepped configuration. The recesses are provided at the lower edge of the perimeter. In particular, the recesses are provided on the first side wall and on the second side wall.The cutouts can extend through the first floor section and through the second floor section.

[0044] According to another embodiment, the drainage base and the rim form a single component, in particular a single component made of the same material.

[0045] "One-piece" or "single-piece" means that the deflector base and the surrounding frame are not composed of different sub-components, but rather form a single component, specifically the cartridge case stub catch device. For example, the cartridge case stub catch device can be a sheet metal bent and stamped component. Alternatively, it can be a welded component. In this case, the deflector base and the surrounding frame can be welded together. The cartridge case stub catch device can also be a combined sheet metal bent, stamped, and welded component. "One-piece material" means that the deflector base and the surrounding frame are manufactured entirely from the same material. The cartridge case stub catch device can be made, for example, from an aluminum sheet or a steel sheet. Fiber-reinforced composite materials can also be used to manufacture the cartridge case stub catch device.It is also possible to mix different materials.

[0046] Furthermore, a vehicle, in particular a main battle tank, is proposed with such a shell casing stub arrestor device, wherein the shell casing stub arrestor device is attached to a turret of the vehicle or to a vehicle hull of the vehicle.

[0047] The vehicle is preferably a tracked vehicle. However, it can also be a wheeled vehicle. The hull is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, or similar hazards. The shell casing stump arrestor can be mounted on the floor of the hull. For example, the shell casing stump arrestor can be welded or bolted to the floor. Torsion bars of the vehicle's track drive run through the hull. The torsion bars pass through the shell casing stump arrestor, at least in sections. For this purpose, the aforementioned recesses are provided on the lower edge of the shell casing stump arrestor. Alternatively, the shell casing stump arrestor can also be mounted on the turret, in particular on the floor of a turret platform. In this case, the turret can, for example, be unmanned.

[0048] The embodiments and features described for the proposed sleeve stub catching device apply accordingly to the proposed vehicle and vice versa.

[0049] The term "one" here should not necessarily be understood as restricting the number to exactly one element. Rather, it can also refer to multiple elements, such as two, three, or more. Similarly, every other counter used here should not be interpreted as restricting the number to the exact number stated. Instead, numerical deviations, both higher and lower, are possible unless otherwise specified.

[0050] Other possible implementations of the sleeve stub arrestor and / or the vehicle also include combinations of features or embodiments described previously or subsequently with regard to the exemplary embodiments, even if not explicitly mentioned. In such cases, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic form of the sleeve stub arrestor and / or the vehicle.

[0051] Further advantageous embodiments and aspects of the cartridge case stub catching device and / or the vehicle are the subject of the dependent claims and the exemplary embodiments of the cartridge case stub catching device and / or the vehicle described below. The cartridge case stub catching device and / or the vehicle are further explained below with reference to preferred embodiments and the accompanying figures. Fig. 1 shows a schematic view of an embodiment of a military vehicle; Fig. 2 shows a schematic perspective view of an embodiment of a cartridge case stub catcher for the vehicle; Fig. 3 shows a schematic front view of the cartridge case stub catcher according to Fig. 2 Fig. 4 shows a schematic sectional view of the cartridge case stub catching device according to section line IV-IV of the Fig. 3 ; Fig. 5 shows the detailed view V according to Fig. 3 ; and Fig. 6 shows the detailed view VI according to Fig. 4 .

[0052] In the figures, identical or functionally equivalent elements have been given the same reference symbols, unless otherwise indicated.

[0053] The Fig. 1 Figure 1 shows a schematic side view of an embodiment of a military vehicle.

[0054] The military vehicle 1 will be referred to simply as "vehicle" below. Vehicle 1 is a highly protected vehicle. For this purpose, Vehicle 1 has armor plating. Vehicle 1 is a tracked vehicle. In particular, Vehicle 1 can be a main battle tank. However, Vehicle 1 can also be an infantry fighting vehicle, a recovery vehicle, or the like. Vehicle 1 can also be a wheeled vehicle. Vehicle 1 is armed.

[0055] Vehicle 1 is assigned a coordinate system with a first spatial direction, longitudinal direction or x-direction x, a second spatial direction, transverse direction or y-direction y, and a third spatial direction, vertical direction or z-direction z. The directions x, y, z are oriented perpendicular to each other. A gravitational direction g can be oriented essentially opposite to the z-direction z.

[0056] Vehicle 1 comprises a protected hull 2, which accommodates the vehicle's crew. The hull 2 ​​is protected against gunfire, booby traps, improvised explosive devices (IEDs), mines, and the like. The hull 2 ​​encloses an interior compartment 3 where the crew can be located. The interior compartment 3 of the hull 2 ​​can be entered and exited from the vehicle's surroundings 4 via hatches or doors.

[0057] The vehicle 1 can have a turret 5 with a gun or armament 6. The turret 5 can also enclose part of the interior 3. Thus, the interior 3 can also be located, at least partially, outside the vehicle hull 2, namely within the turret 5. The turret 5 is rotatably mounted on the vehicle hull 2. The turret 5 can include an electric or hydraulic drive for rotation. However, the turret 5 can also be operated manually if the drive fails. The armament 6 can be a smoothbore gun. The armament 6 can be primary or main armament. For example, the armament 6 can have a caliber of 130 mm. A secondary armament, for example in the form of a machine gun, can also be provided.

[0058] The vehicle 1 further comprises a tracked undercarriage 7, by means of which the vehicle 1 can move on a surface 8 in a direction of travel 9. However, this does not preclude the vehicle 1 from also moving in the opposite direction to the direction of travel 9, for example in reverse. In the orientation of the Fig. 1 The direction of travel 9 is oriented along the x-direction x.

[0059] The track assembly 7 comprises a circulating chain 10, which is driven by a drive roller 11. The drive roller 11 is located at the rear. In the orientation of the Fig. 1 When the vehicle 1 moves in the direction of travel 9, the chain 10 rotates clockwise. The chain 10 can have a large number of interconnected chain links that are movably connected to one another. The chain links are made of a metallic material, such as steel. However, the chain 10 can also be a rubber chain or have elements made of rubber.

[0060] The drive roller 11 is operatively connected to a drive system of the vehicle 1. The drive system can, for example, comprise an internal combustion engine, in particular a diesel engine, and a transmission. Furthermore, the track assembly 7 comprises a plurality of track rollers 12, of which in the Fig. 1 Only one is marked with a reference symbol. For example, seven such track rollers 12 are provided on each side of the vehicle 1. However, the number of track rollers 12 is generally arbitrary. Furthermore, the track assembly 7 includes a deflection roller 13. The deflection roller 13 is located at the front. Conversely, the drive roller 11 can also be located at the front and the deflection roller 13 at the rear.

[0061] The track assembly 7 preferably comprises two tracks 10 arranged on both sides of the vehicle 1 when viewed along the direction of travel 9. Accordingly, the track assembly 7 also comprises a pair of drive rollers 11 arranged on both sides of the vehicle 1, any number of track rollers 12 also arranged on both sides of the vehicle 1, and a pair of deflection rollers 13.

[0062] The Fig. 2 Figure 1 shows a schematic perspective view of a cartridge case stub catching device 14 for vehicle 1, in particular for armament 6. Fig. 3 shows a schematic front view of the cartridge case stub catching device 14. Fig. 4 shows a schematic sectional view of the cartridge stub catching device 14 according to section line IV-IV of the Fig. 3 . The Fig. 5 The detailed view V shows according to the Fig. 3 . The Fig. 6 The detailed view VI shows according to the Fig. 4 The following refers to the Fig. 2 bis 6 Reference was made at the same time.

[0063] The cartridge case stub catching device 14 is designed to collect cartridge case stubs 15 ejected, expelled, or extracted from the armament 6, some of which are in the Fig. 2 The cartridge cases 15 are shown to be collected. They are part of a cartridge or cartridge ammunition of the weapon 6. Such cartridge ammunition consists of a casing, a propellant charge, and a projectile. When the weapon 6 is fired, a hollow cylindrical part of the casing burns away, leaving only the cartridge case 15. The cartridge case 15 has a metallic base 16 and a firing tube 17 welded to it. Each cartridge case 15 can have a length of, for example, 300 millimeters.

[0064] The aforementioned geometry and dimensions of the cartridge case stub 15 can lead to handling problems, particularly when using an automatic loader for the armament 6. These handling problems include, for example, damage to sensitive components of the turret 5 when picking out the cartridge case stub 15, or jamming of the cartridge case stub 15 during aiming movements of the armament 6. Furthermore, it is undesirable for the cartridge case stub 15 to lie undefined beneath the turret 5 in the vehicle hull 2.

[0065] Furthermore, the spent cartridge cases 15 cannot be visually inspected and manually sorted and / or disposed of on an unmanned turret 5. Accidentally erect spent cartridge cases 15 can collide with the breech of the armament 6 when the armament 6 is fired. Loose spent cartridge cases 15 can become secondary projectiles if the vehicle 1 is carrying a mine. These problems mentioned above can be solved or at least reduced with the aid of the spent cartridge case catching device 14.

[0066] As the Fig. 3 and 4 As shown, the cartridge case stub arrestor 14 is arranged on a base 18 of the vehicle tub 2. The cartridge case stub arrestor 14 can be screwed to the base 18. The base 18 has an outer surface 19 facing the surroundings 4 and an inner surface 20 facing the interior 3. The cartridge case stub arrestor 14 is arranged on or at the inner surface 20. In the orientation of the Fig. 3 and 4Above the floor, 18 torsion bars 21 of the track drive 7 run along the y-direction y through the vehicle body 2. The number of torsion bars 21 is arbitrary. In the Fig. 4 Two torsion bars 21 are shown as examples, only one of which is labeled. The torsion bars 21 thus extend through the interior 3. The torsion bars 21 can lie in recesses 22 provided on the inner surface 20 of the base 18. However, this is not mandatory. Alternatively, the sleeve stub catch device 14 can also be mounted on the tower 5, in particular on a floor of a tower platform of the tower 5.

[0067] The cartridge case stub arrestor 14 can be a sheet metal bent and stamped component. For example, the cartridge case stub arrestor 14 can be made of an aluminum alloy, in particular aluminum sheet. The cartridge case stub arrestor 14 can also be made of steel sheet. However, fiber composite materials can also be used. A combination of different materials can also be used to manufacture the cartridge case stub arrestor 14.

[0068] The spent cartridge case stub catcher 14 comprises a frame 23, which, however, does not completely encircle the spent cartridge case stub catcher 14, but is open at the front, i.e., in the direction of the armament 6. The frame 23 has a first side wall 24 and a second side wall 25. The side walls 24, 25 are spaced apart from each other along the y-direction y and are positioned parallel to each other. The side walls 24, 25 are oriented parallel to a plane spanned by the x-direction x and the z-direction z. Each side wall 24, 25 has an opening 26, 27. The openings 26, 27 allow a view through the side walls 24, 25, in order, for example, to check how full the spent cartridge case stub catcher 14 is with spent cartridge cases 15.

[0069] A rear wall 28 is arranged between the two side walls 24, 25. The rear wall 28 also has an opening 29. The rear wall 28 is oriented perpendicular to the side walls 24, 25. The first side wall 24 is connected to the rear wall 28 by means of a first connecting wall 30, which runs at an angle to the first side wall 24. The first connecting wall 30 is also oriented at an angle to the rear wall 28. The second side wall 25 is connected to the rear wall 28 by means of a second connecting wall 31, which runs at an angle to the second side wall 25. The second connecting wall 31 is also oriented at an angle to the rear wall 28. Each connecting wall 30, 31 has an opening 32, 33.

[0070] The border 23 has a orientation of Fig. 2 bis 4 lower edge 34 provided on the underside and one in the orientation of the Fig. 2 bis 4 The upper edge 35 is provided on the upper side. Recesses 36, 37 for the torsion bars 21 are provided on the lower edge 34. In particular, the side walls 24, 25 have the recesses 36, 37. The torsion bars 21 can thus be guided through the sleeve stub retainer 14, at least partially. The number of recesses 36, 37 is arbitrary. For example, two, three, four, or more than four such recesses 36, 37 can be provided. In particular, such recesses 36, 37 can also be provided in the area of ​​the rear wall 28.

[0071] At the upper edge 35, catch elements 38 are provided, of which in the Fig. 2 bis 4 Only one of the retaining elements is marked with a reference symbol. The retaining elements 38 are triangular or tooth-shaped. The retaining elements 38 can be attached to the side walls 24, 25, the rear wall 28, and / or the connecting walls 30, 31. Starting from the upper edge 35, the retaining elements 38 project obliquely downwards towards the lower edge 34 into an interior space 39 of the cartridge case stub retaining device 14, which is bounded by the rim.

[0072] As in the Fig. 5 As shown with reference to the first side wall 24, the catch elements 38 are each inclined at a catch element inclination angle α relative to the side walls 24, 25, the rear wall 28 and / or the connecting walls 30, 31. The catch element inclination angle α is less than 90°, so that a tip 40 of the respective catch element 38 projects obliquely downwards into the interior 39. The tip 40 may be chamfered. This can result in a hook-shaped or barbed geometry of the tip 40.

[0073] In addition to the rim 23, the sleeve stub catching device 14 has a deflecting base 41 which is connected to the rim 23. The deflecting base 41 comprises a central base section 42 with an opening 43 for a slip ring (not shown). The base section 42 is positioned parallel to and spaced apart from the lower edge 34 and the upper edge 35. Viewed along the z-direction z, the base section 42 is thus positioned between the lower edge 34 and the upper edge 35. In particular, the base section 42 lies in a plane 44 which is arranged parallel to both a plane 45 spanned by the lower edge 34 and a plane 46 spanned by the upper edge 35.

[0074] The base floor section 42 is connected to the first side wall 24 by means of a first floor section 47. The first floor section 47 extends obliquely from the base floor section 42 to the lower edge 34. The first floor section 47 is thus inclined at a first base floor section inclination angle β1 relative to the base floor section 42 or to the plane 44. The first base floor section inclination angle β1 can be, for example, 10° to 20°. The first floor section 47 can also be connected to the first connecting wall 30. The recesses 36, 37 extend into the first floor section 47. Furthermore, the first floor section 47 is inclined at a first floor section inclination angle γ1 relative to the first side wall 24. The first floor section inclination angle γ1 is less than 90°.

[0075] The base floor section 42 is further connected to the second side wall 25 by means of a second floor section 48. The second floor section 48 extends obliquely from the base floor section 42 to the lower edge 34. The second floor section 48 is thus inclined at a second base floor section inclination angle β2 relative to the base floor section 42 or to the plane 44. The second base floor section inclination angle 62 can be, for example, 10° to 20°. The two base floor section inclination angles β1, β2 are equal. The second floor section 48 can also be connected to the second connecting wall 31. Recesses 36, 37, as previously mentioned, also extend into the second floor section 48. The second floor section 48 is further inclined at a second floor section inclination angle y2 relative to the second side wall 25. The second floor section inclination angle y2 is less than 90°.The soil section inclination angles γ1, γ2 can be equal.

[0076] The drainage floor 41 further comprises a third floor section 49, which connects the base floor section 42 to the rear wall 28. Additionally, the third floor section 49 can connect the base floor section 42 to the two connecting walls 30, 31. The third floor section 49 extends obliquely downwards from the base floor section 42 towards the lower edge 34. The third floor section 49 is thus inclined at a third base floor section inclination angle β3 relative to the base floor section 42 or the plane 44. The third base floor section inclination angle β3 can, for example, be 10° to 20°. The third base floor section inclination angle β3 and the base floor section inclination angles β1, β2 can be equal. However, this is not mandatory. The third floor section 49 is also inclined at a third base floor section inclination angle γ3 relative to the rear wall 28. The third soil section inclination angle γ3 is less than 90°.

[0077] The first floor section 47 is connected to the second floor section 48 by means of the third floor section 49. Viewed along the y-direction y, the third floor section 49 is thus positioned between the first floor section 47 and the second floor section 48. Because the first floor section 47 and the second floor section 48 are inclined relative to the first side wall 24 and the second side wall 25, and because the third floor section 49 is inclined relative to the rear wall 28, the drainage floor 41 has a truncated pyramidal shape, at least in sections. This means that all floor sections 47, 48, 49 slope obliquely from the base floor section 42 towards the lower edge 34.

[0078] A mounting platform 50 can be attached to the first floor section 47, on which steps 51, 52 are mounted for entering and exiting the cartridge case stub retrieval device 14. This facilitates the removal of the cartridge case stubs 15 from the cartridge case stub retrieval device 14.

[0079] The first soil section 47, the second soil section 48 and / or the third soil section 49 can, as in the Fig. 6As exemplified by the third base section 49, the bottom section 41 is at least partially or completely covered with ball rollers 53. This facilitates the transport of the sleeve stubs 15 from the base section 42 of the discharge base 41 outwards towards the perimeter 23. For mounting the ball rollers 53, openings 54 are provided in the respective base sections 47, 48, 49, in which a respective housing 55 of the ball roller 53 is received. The housing 55 can rest with a collar 56 on a front surface 57 of the respective base section 47, 48, 49 facing the interior 39, and the housing 55 can project beyond a rear surface 58 of the respective base section 47, 48, 49. The collar 56 can also be arranged flush with the front surface 57. A freely rotatable ball 59 is received in the housing 55.

[0080] The functionality of the cartridge case stub catching device 14 is explained below. Due to the inclined position of the base sections 47, 48, 49 and the provision of the ball rollers 53 on the base sections 47, 48, 49, cartridge case stubs 15 striking the deflecting base 41 are guided outwards towards the rim 23 and come to rest on the deflecting base 41. The movement of the cartridge case stubs 15 on the deflecting base 41 towards the rim 23 is due to gravity, i.e., due to the respective weight of the cartridge case stubs 15.

[0081] With the aid of the retaining elements 38, shell casing stubs 15 sliding towards the perimeter 23 are either tipped over or fixed in such a way that they cannot be ejected from the shell casing stub retaining device 14, for example, in the event of a mine explosion affecting the vehicle 1. The same applies to shell casing stubs 15 that have already tipped over and come to rest on the deflector plate 41 below the retaining elements 38.

[0082] The deflector plate 41 allows the cartridge stubs 15 to slide sideways under the turret 5, thus preventing a collision with the breech of the armament 6. Lying cartridge stubs 15 roll to the side. Upright cartridge stubs 15 slide to the side, but the firing tube 17 is angled to prevent a collision with the breech. The retaining elements 38 secure both lying and upright cartridge stubs 15 and minimize the risk of secondary projectiles in the event of a mine attack on the vehicle 1. The additional ball rollers 53 facilitate the rolling and sliding of the cartridge stubs 15. The cartridge stub retaining device 14 can be used not only for cartridge stubs 15 but also for complete cartridge cases. REFERENCE MARK LIST
