Description

The present invention relates to a sliding door module for a vehicle, in particular for a combat armour, a tower for a vehicle, in particular for a combat armour, having such a sliding door module, and a vehicle, in particular a combat armour, having such a sliding door module and / or such a tower.According to in-house findings, so-called automatic loaders can be used in combat armour, which can each remove a piece of patronized ammunition from a magazine and feed it to a cartridge store of an arming for the combat armour, for example a smooth tube gun. In automatic loaders of this type, however, there is the need for the patronized ammunition to be stored as close as possible to the cartridge store. This allows short loading cycles due to a short feed path between the magazine and the cartridge store and thus an increase in the firing rate, which in turn has a positive effect on the operative value of the combat tank.This short feed path from the magazine to the cartridge store can, however, entail disadvantages, in particular with regard to the safety of the crew of the combat armour. The safety of the crew and the combat armour is also to be ensured if the magazine explodes in the event of an accident or a hit. This requires a separation between the magazine and a crew room in which the crew is located. In other words, neither a shock wave generated by an explosion nor fragments generated by the explosion, for example fragments, must reach the crew.Against this background, it is an object of the present invention to provide an improved sliding door module for a vehicle, in particular for combat armour.Accordingly, a sliding door module for a vehicle, in particular for combat armour, is proposed. The sliding door module comprises a sliding door and a guide device on which the sliding door is guided so as to be linearly displaceable along a direction of movement in order to move the sliding door from an open state to a closed state and counter to the direction of movement from the closed state to the open state, wherein the sliding door is oriented at an angle of inclination obliquely to the direction of movement.Due to the fact that the sliding door is oriented obliquely to the direction of movement at the angle of inclination, it is possible to achieve the result that, owing to the oblique position of the sliding door, a distance is increased which fragments which act on the sliding door and are caused by an explosion must travel through the sliding door. This reduces the risk that the fragments can penetrate the sliding door, whereby improved protection for crew shielded by the sliding door can be achieved. In addition, by appropriately selecting the inclination angle, it is possible for a pressure wave resulting from explosion to press the sliding door toward the closed state. This can ensure that, in the event of an emergency, closing of the sliding door is assisted by means of the pressure shaft and / or the sliding door cannot be moved from the closed state to the open state by the pressure shaft. This achieves additional protection for the crew.The vehicle is preferably a tracked vehicle. The vehicle is particularly preferably a combat armour. Accordingly, in the present case, the terms "vehicle", "tracked vehicle" and "combat armour" can be interchanged with one another as desired. However, the vehicle may also be a wheeled vehicle. The sliding door module is mounted on the vehicle. The sliding door module may be removably mounted to the vehicle. For this purpose, a screw connection can be provided, for example. In particular, the sliding door module is mounted on a bulkhead of the vehicle, which separates an ammunition compartment from a crew compartment. The bulkhead can be part of an, in particular rotatable, tower of the vehicle. A door opening can be provided on the bulkhead, which can be closed with the aid of the sliding door.A "module" is preferably understood in the present case as a cuboidal or box-shaped assembly which can be transported and / or mounted as a unit. The sliding door module is thus preferably a transportable compact unit which can be raised and transported, for example, with the aid of a hall crane, in order to mount the sliding door module on the vehicle and to disassemble it from the latter. This enables a flexible use of the sliding door module and in particular also a simple and rapid replacement thereof even under difficult conditions.The sliding door is preferably plate-shaped. For example, the sliding door can be a steel armor plate. A "sliding door" is to be understood in the present case in particular as a door which is moved along and counter to the direction of movement for opening and closing and which is in particular not pivoted about an axis for opening and closing. The sliding door preferably has a front side or first surface facing a ammunition compartment of the vehicle as mentioned above and a rear side or second surface facing away from the first surface. The two surfaces of the sliding door are preferably arranged parallel to one another. The second surface is oriented toward a crew compartment of the vehicle as mentioned above. In particular, the first surface forms a plane of the sliding door which is oriented obliquely to the direction of movement at the angle of inclination. In other words, the first surface lies in the plane of the sliding door.With the aid of the guide device, the sliding door can be moved from the open state to the closed state and vice versa. In this case, the sliding door is guided along and counter to the direction of movement with the aid of the guide device. The sliding door is coupled to the guide device for this purpose. However, the sliding door can be separated from the guide device. This may be advantageous, for example, in an emergency. In this case, the sliding door can be separated from the guide device manually, for example. The guide device is a linear guide device and can therefore also be referred to as such. In the present case, a "moving" of the sliding door is to be understood as meaning that the sliding door is moved or moved from the open state to the closed state and vice versa. The terms "move", "method" and "move" can therefore be interchanged with one another as desired in the present case.The sliding door is particularly preferably oriented, tilted or inclined at the angle of inclination relative to the direction of movement in such a way that a pressure wave acting on the sliding door, in particular on the first surface of the sliding door, generates a resulting closing force which is oriented along the direction of movement. The closing force either moves the sliding door from the open state toward the closed state or presses the sliding door, if the sliding door is already in the closed state, against a seal of the sliding door module and / or against the guide device. In particular, the closing force assists a movement of the sliding door along the direction of movement from the open state toward the closed state.In other words, the closing force thus acts in particular in the direction of the closed state of the sliding door. This has the result, in particular, that the closing force moves or moves the sliding door from the open state to the closed state or, in the case that the sliding door is already in the closed state, holds the sliding door in the closed state. The pressure shaft can thus not push open the sliding door or move or bring it from the closed state and the open state. "Oblique" in the present case means that the angle of inclination is not 90°.Particularly preferably, a sliding door module for a vehicle, in particular for combat armour, is accordingly proposed, wherein the sliding door module has a sliding door and a guide device, on which the sliding door is guided in a linearly displaceable manner along a direction of movement in order to move the sliding door from an open state into a closed state and counter to the direction of movement from the closed state into the open state, wherein the sliding door is oriented at an angle of inclination obliquely to the direction of movement such that a pressure wave acting on the sliding door generates a resulting closing force which is oriented along the direction of movement.According to one embodiment, the angle of inclination is sharp, wherein the angle of inclination is preferably 7° to 15°, further preferably 8° to 14°, further preferably 9° to 13°, further preferably 10° to 12°, further preferably 11°, and wherein the angle of inclination is negative.The fact that the angle of inclination is "acute" or an "acute angle" is to be understood here in particular as meaning that the angle of inclination is less than 90°. The fact that the angle of inclination is "negative" or a "negative angle" is to be understood in the present case in particular as meaning that the angle of inclination results from a right-hand rotation or a rotation of the sliding door or the first surface of the sliding door in the clockwise direction with respect to the direction of movement. In contrast, a "positive angle" would be understood to mean an angle of inclination of the sliding door or the first surface of the sliding door with respect to the direction of movement, which angle of inclination results from a leftward rotation or a rotation of the sliding door or the first surface of the sliding door in the counterclockwise direction with respect to the direction of movement.According to a further embodiment, the sliding door is oriented obliquely in the angle of inclination to a plane spanned by a longitudinal direction and a vertical direction of the sliding door module.Preferably, the sliding door module is assigned a first spatial direction, longitudinal direction or x-direction, a second spatial direction, transverse direction or y-direction, and a third spatial direction, vertical direction or z-direction. The directions are oriented perpendicular to each other. As mentioned above, the longitudinal direction and the vertical direction span the plane. Furthermore, the sliding door is assigned the aforementioned plane of the sliding door, in which plane the first surface of the sliding door can lie. This plane assigned to the sliding door is arranged or oriented in particular at an inclination angle obliquely to the plane spanned by the longitudinal direction and the vertical direction.According to a further embodiment, the guide device has an upper linear guide and a lower linear guide arranged at a distance from the upper linear guide, wherein the sliding door is guided on the upper linear guide and on the lower linear guide so as to be linearly displaceable along the direction of movement.The upper linear guide and the lower linear guide are arranged spaced apart from one another when viewed along the vertical direction. The upper linear guide and the lower linear guide preferably run parallel to one another. The sliding door is arranged between the upper linear guide of the lower linear guide when viewed along the vertical direction. The sliding door is coupled to both the upper linear guide and the lower linear guide. The linear guides extend in particular along the direction of movement or the longitudinal direction. The linear guides can be designed as C-profiles with a C-shaped cross section. The linear guides preferably do not form a closed frame surrounding the sliding door. The sliding door module is thus frameless or frameless. However, the linear guides can be connected to a supporting plate of the sliding door module. For example, the linear guides can be screwed to the supporting plate. The support plate may be a steel plate. The support plate can support the linear guides and further components or components of the sliding door module. The sliding door module can be mounted on the vehicle, in particular on the bulkhead of the vehicle, with the aid of the support plate. The support plate can be part of the guide device.According to a further embodiment, the sliding door is oriented obliquely to the upper linear guide and obliquely to the lower linear guide in the angle of inclination.In particular, the first surface of the sliding door is oriented obliquely to the upper linear guide and obliquely to the lower linear guide in the angle of inclination. The upper linear guide and the lower linear guide preferably each have a front surface. The two front surfaces of the linear guides are arranged in a common plane of the linear guides. This plane of the linear guides particularly preferably runs parallel to the plane which is spanned by the longitudinal direction and the vertical direction. The plane of the sliding door, in which the first surface of the sliding door lies, is preferably arranged at an inclination angle obliquely to the plane of the two linear guides.According to a further embodiment, the sliding door is coupled to the upper linear guide with the aid of at least one upper coupling element, wherein the sliding door is coupled to the lower linear guide with the aid of at least one lower coupling element.For example, the upper linear guide is assigned at least one upper guide slide which can be moved along and counter to the direction of movement along the upper linear guide. The upper coupling element is connected to the upper guide slide. Particularly preferably, a first upper guide slide and a second upper guide slide are provided. Each upper guide slide can be assigned a plurality of rollers or sliding elements which are arranged within the upper linear guide. Accordingly, the lower linear guide is likewise assigned at least one lower guide slide which can be moved along and counter to the direction of movement along the lower linear guide. The lower coupling element is connected to the lower guide slide. Particularly preferably, a first lower guide slide and a second lower guide slide are provided. Each lower guide slide can be assigned a plurality of rollers or sliding elements which are arranged within the lower linear guide. The sliding door is operatively connected or coupled indirectly to the guide device, in particular to the upper linear guide, in particular by means of two upper coupling elements via the upper guide slides. The upper coupling elements can be welded to the sliding door, in particular to the first surface of the sliding door. The sliding door is preferably also operatively connected or coupled indirectly to the guide device, in particular to the lower linear guide, by means of two lower coupling elements via the lower guide slides. The lower coupling elements can likewise be welded to the sliding door, in particular to the first surface of the sliding door. The upper coupling elements can be screwed to the upper guide slides. Accordingly, the lower coupling elements can be screwed to the lower guide slides. However, any other type of connection can also be provided.According to a further embodiment, the at least one upper coupling element can be decoupled from the upper linear guide with the aid of at least one upper quick-release element, and / or wherein the at least one lower coupling element can be decoupled from the lower linear guide with the aid of at least one lower quick-release element.The quick release elements can be screws, for example. For example, two upper quick release elements and two lower quick release elements are provided. However, the lower quick release elements are optional. Alternatively, only lower quick release elements can also be provided. By releasing the upper quick release elements, the sliding door can be manually separated from the upper guide slides and disconnected from the guide device. In this case, the lower guide slides and / or the lower coupling elements are configured such that the sliding door can be disconnected from the lower linear guide. In the event that lower quick release elements are also provided, these can also be released in order to separate the sliding door from the guide device. This can be advantageous, for example, in an emergency in order to be able to manually remove or open the sliding door. Instead of screws, any other quick-release fasteners can be used as quick-release elements.According to a further embodiment, the sliding door module has a drive connected to the guide device for moving the sliding door from the open state to the closed state and vice versa, and / or a brake connected to the guide device for braking the sliding door when moving the sliding door from the open state to the closed state and vice versa.The drive and / or the brake can be part of the guide device. The sliding door module can have a plurality of drives. However, only one drive is referred to below. The drive can be an electric motor, in particular a rotary electric motor or a linear drive. The drive can be a servomotor or a servomotor. A servomotor or servomotor allows control of an angular position of a motor shaft of the servomotor or servomotor and a rotational speed and acceleration thereof. Such a servomotor or servomotor comprises an electric motor which is additionally equipped with a sensor for position determination. A rotational position of the motor shaft determined by the sensor can be transmitted continuously to a control unit of the sliding door module. As a result, it is possible, for example, to continuously monitor a position of the sliding door. In the case where the drive is a linear drive, it can be integrated into one of the linear guides. Such a drive can also be integrated into each of the two linear guides. In the case that, for example, only the lower linear guide is assigned a drive, this can be operatively connected, for example, to the lower guide slides in order to move these along and counter to the direction of movement along the lower linear guide. In this exemplary case, a force transmission is effected via the lower coupling elements from the lower guide slides to the sliding door in order to move the latter with the aid of the drive from the open state to the closed state and vice versa. In order to couple the drive to the lower guide slides, a belt drive or a pinion and a toothed rack or the like can be provided, for example. The drive can be connected, for example, firmly to the lower linear guide and / or to the aforementioned support plate. The brake can be fixedly connected to the guide device. The brake may be an eddy current brake. However, the brake may also be a friction brake. The brake can be integrated into the drive or mounted on the drive. However, the brake can also be integrated into one or both of the linear guides.According to a further embodiment, the sliding door module has a control unit and / or an emergency power supply and a housing connected to the guide device, in which housing the control unit and / or the emergency power supply are arranged.The housing can be connected, for example, to the support plate and / or to one or both of the linear guides. With the aid of the control unit, the drive and / or the brake can be actuated in order to move the sliding door from the open state to the closed state and vice versa. The control unit is preferably an analog circuit or comprises an analog circuit. This makes the control unit insensitive to faults, so that the sliding door can be closed and / or opened, for example, even in the event of a failure of onboard electronics of the vehicle. The control unit is preferably part of the guide device. With the aid of the emergency power supply, the drive and / or the control unit can be energized, for example, in the event of a failure of an on-board power supply of the vehicle, in order to close and / or open the sliding door. The emergency power supply can have one or more accumulators. With the aid of the emergency power supply, autonomous operation of the sliding door module is possible, for example, in an emergency.According to a further embodiment, the sliding door module has a movement range monitoring device, in particular having a light barrier and / or a camera, for monitoring a movement range of the sliding door.With the aid of the movement range monitoring, damage to the crew and / or jamming of objects by the moving sliding door can be reliably prevented. In the range of movement, the sliding door moves when moving it from the open state to the closed state and vice versa. The movement range monitoring provides sensor signals to the control unit. The sensor signals can comprise, for example, a respective position of the sliding door. A data connection can be provided between the movement range monitoring and the control unit. This data connection can be wireless or wired. The movement range monitoring can be part of the guide device. For example, the movement range monitoring system comprises a first light barrier and a second light barrier, which can be provided on the end side of the movement range. The light barriers can be fastened to the support plate. In the event that a camera is provided, it can likewise be mounted on the supporting plate.According to a further embodiment, the sliding door module has an end position monitoring for monitoring end positions of the sliding door in the open state and / or in the closed state.The end position monitoring is preferably part of the guide device. For example, the end position monitoring can have a first end position sensor, which can be associated with an end position of the sliding door in the open state, and a second end position sensor, which can be associated with an end position of the sliding door in the closed state. The end position sensors can be mounted on the support plate. Any number of end position sensors can be provided. The end position sensors can be switches, optical sensors, inductive sensors, capacitive sensors or the like, for example. The end position monitoring provides sensor signals to the control unit. The sensor signals can comprise a respective position of the sliding door in its respective end position. A data connection can be provided between the end position monitoring and the control unit. This data connection can be wireless or wired.According to a further embodiment, the sliding door module has a seal sealing the sliding door in a gas-tight manner in the closed state.The seal is preferably mounted on the support plate. In this case, the supporting plate preferably has a door opening aperture around which the seal runs, in particular completely. The seal is preferably made of an elastic material, such as rubber or polyurethane. In the closed state, the sliding door presses the seal between the second surface of the sliding door and the support plate. The seal is preferably wedge-shaped in cross section and comprises a first sealing surface against which the sliding door abuts in the closed state and a second sealing surface which abuts on the supporting plate. The first sealing surface is in particular inclined at the angle of inclination relative to the direction of movement. This means in particular that the first sealing surface can be arranged parallel to the second surface of the sliding door. However, the seal may have any cross-sectional shape in cross section. In particular, the seal can be constant or constant in cross section. If necessary, the seal can be mounted on a carrier having a wedge-shaped cross section. This support can then be arranged between the support plate and the seal and be connected to the support plate.According to a further embodiment, the sliding door makes contact with the seal only immediately before the closed state is reached, in order to press the seal.In the present case, "only immediately before" can be understood in particular to mean that the sliding door contacts the seal for example 0.1 to 10 millimeters before reaching the closed state in order to subsequently press the seal. Due to the fact that the sliding door contacts the seal only immediately before reaching the closed state, it can be achieved that the sliding door can be moved very quickly from the open state into the closed state, since the sliding door does not slide against the seal during its movement. This is preferably achieved in that the seal is wedge-shaped in cross section and the first sealing surface is inclined at the angle of inclination. Alternatively, the seal can also be arranged on a wedge-shaped carrier as mentioned above. In this case, the seal can have, for example, a rectangular, oval, circular or triangular cross section. The seal can also be a round seal, in particular a sealing cord. In particular, the first sealing surface forms a plane of the seal which is inclined at the angle of inclination relative to the plane spanned by the longitudinal direction and the vertical direction. The first sealing surface is accordingly also inclined at the angle of inclination relative to the direction of movement.Furthermore, a tower for a vehicle, in particular for combat armour, is proposed. The turret comprises such a sliding door module, wherein the sliding door module is attached to a bulkhead of the turret, wherein the bulkhead is arranged between a ammunition compartment of the turret and a crew compartment of the turret, and wherein the sliding door module is arranged in the ammunition compartment.The bulkhead is in particular a armour steel plate. The bulkhead preferably has a door opening as mentioned above, which is released in the open state of the sliding door. In the closed state of the sliding door, the latter covers the door opening. The bulkhead preferably has a first surface facing the ammunition compartment and a second surface facing the crew compartment. The sliding door module is mounted in particular on the first surface. In this case, for example, the support plate is screwed to the bulkhead. Patronized ammunition for an arming of the vehicle can be located in the ammunition chamber. The patroned ammunition can be accommodated in a magazine of the turret. Furthermore, an automatic loader, for example comprising a robot, can be arranged in the ammunition chamber, which is suitable for supplying a respective piece of the patronized ammunition through the doorway of the bulkhead wall to a cartridge store of the weapon. The sliding door is moved from the closed state to the open state only when the car loader is to feed the patroned ammunition to the cartridge store. The opening and closing of the sliding door can take less than 0.5 seconds, for example. The moving of the sliding door from the closed state to the open state can be effected by the crew, for example by giving a corresponding command to the control unit for opening the sliding door. In the simplest case, this can be effected, for example, by actuating a switch arranged in the crew room. However, the sliding door is particularly preferably opened and closed with the aid of a direct signal and / or an indirect signal of the automatic loader and thus automatically. As soon as the sliding door is in the open state, the automatic loader reaches the pattroned ammunition through the door opening into the cartridge store and then immediately draws it back into the ammunition chamber. Once the automatic loader has retracted from the doorway, the sliding door is immediately moved from the open state back to the closed state. This protects the crew in the crew room even when the ammunition room suffers, for example, a hit which leads to an explosion of the patronized ammunition in the magazine. However, the bulkhead does not necessarily have to be part of such a tower. For example, the bulkhead can also be part of a vehicle trough of the vehicle or of any desired structure of the vehicle. In this case, however, the bulkhead preferably likewise separates an ammunition compartment of the vehicle from a crew compartment of the vehicle.Furthermore, a vehicle, in particular a combat armour, with such a sliding door module and / or such a tower is proposed.The vehicle is a highly protected vehicle. For this purpose, the vehicle has armouring. The vehicle is particularly preferably a tracked vehicle. In particular, the vehicle can be combat armour. The vehicle can, however, also be a protective armour, a rescue armour or the like. The vehicle can also be a wheeled vehicle. The vehicle can also be a howitzer, in particular a wheel howitzer or an armor-plated howitzer. The vehicle comprises, in addition to the tower, preferably a vehicle trough as mentioned above. The tower is rotatable about an axis of rotation relative to the vehicle sump. The tower has the aforementioned weapon. The weapon may be, for example, a smooth tube gun. However, the tower is not absolutely necessary.The embodiments and features described for the proposed sliding door module apply correspondingly and vice versa to the proposed tower and to the proposed vehicle."An" is not necessarily to be understood as limiting to exactly one element. Rather, a plurality of elements, such as two, three or more, can also be provided. Any other counting word used here is also not to be understood as being limited to exactly the number of elements mentioned. Instead, numerical deviations upwards and downwards are possible unless indicated to the contrary.Further possible implementations of the sliding door module, the tower and / or the vehicle also comprise combinations, not explicitly mentioned, of features or embodiments described above or below with respect to the exemplary embodiments. In this case, the person skilled in the art will also add individual aspects as improvements or additions to the respective basic shape of the sliding door module, of the tower and / or of the vehicle.Further advantageous embodiments and aspects of the sliding door module, the tower and / or the vehicle are the subject matter of the dependent claims and of the exemplary embodiments of the sliding door module, the tower and / or the vehicle described below. In the following, the sliding door module, the tower and / or the vehicle are explained in more detail on the basis of preferred embodiments with reference to the enclosed figures.

The directions x, y, z are oriented perpendicular to one another. A direction of gravity g can be oriented substantially counter to the z-direction z.The vehicle 1 comprises a protected vehicle hull 2, in which a crew of the vehicle 1 is located. The vehicle hull 2 is protected against bombardment, blasting traps, non-conventional blasting or firing devices (USBV, Enhanced Explosive Devices, IED), mine or the like. The vehicle sump 2 encloses an interior 3 in which the crew can remain. Doors or doors can be used to enter the interior 3 of the vehicle trough 2 from an environment 4 of the vehicle 1 and to leave it again.The vehicle 1 may have a tower 5 with an arming 6. The tower 5 can also enclose a part of the interior space 3. Thus, the interior 3 can also be arranged at least in sections outside the vehicle trough 2, namely in the tower 5. The tower 5 is rotatably mounted on the vehicle hull 2. The tower 5 may comprise an electric or hydraulic drive to rotate the tower 5. However, the tower 5 can also be operated manually if the drive fails. The weapon 6 may be a smooth tube gun. The order 6 may be a primary order or a main order. For example, the casing 6 can have a caliber of 130 mm. A secondary arming, for example in the form of a machine gun, can additionally be provided.The vehicle 1 further comprises a track drive 7, with the aid of which the vehicle 1 can move on a ground 8 in a direction of travel 9. However, this does not exclude that the vehicle 1, for example in a reverse gear, can also move in the opposite direction to the direction of travel 9. In the orientation of FIG. 1, the direction of travel 9 is oriented along the x-direction x.The chain drive 7 comprises a revolving chain 10 which is driven by a drive roller 11. The drive roller 11 is provided at the rear. In the orientation of FIG. 1, the chain 10 rotates clockwise during a movement of the vehicle 1 in the direction of travel 9. The chain 10 may include a plurality of interconnected chain links movably interconnected. The chain links are made of a metallic material, such as steel. However, the chain 10 may also be a rubber chain or comprise elements made of rubber.The drive roller 11 is operatively connected to a drive of the vehicle 1. The drive can comprise, for example, an internal combustion engine, in particular a diesel engine, and a transmission. Furthermore, the chain drive 7 comprises a plurality of chain running rollers 12, of which only one is provided with a reference sign in FIG. 1. For example, seven such chain pulleys 12 are provided on both sides of the vehicle 1, respectively. The number of chain running rollers 12 is, however, basically arbitrary. Furthermore, the track drive 7 comprises a deflection roller 13. Conversely, the drive roller 11 can also be arranged on the front side and the deflection roller 13 on the rear side.The track drive 7 preferably comprises two tracks 10, which are arranged on both sides of the vehicle 1, as viewed along the direction of travel 9. Accordingly, the track drive 7 also comprises a pair of drive rollers 11 arranged on both sides of the vehicle 1, any number of track rollers 12 which are likewise arranged on both sides of the vehicle 1, and a pair of deflection rollers 13.FIG. 2 shows a schematic front view of an embodiment of a sliding door module 14 for the vehicle 1. FIG. 3 shows a further schematic front view of the sliding door module 14. FIG. 4 shows a schematic sectional view of the sliding door module 14 according to the section line IV-IV of FIG. 2.A "module" is preferably understood in the present case as a cuboidal or box-shaped assembly which can be transported and / or mounted as a unit. The sliding door module 14 is thus preferably a transportable compact unit which can be lifted and transported, for example, with the aid of a hall crane, in order to mount the sliding door module 14 on the vehicle 1 or to disassemble it therefrom. This enables flexible use of the sliding door module 14 and in particular also simple and rapid replacement thereof even under difficult conditions.The sliding door module 14 is mounted on a bulkhead 15 of the tower 5. The bulkhead 15 spatially separates an ammunition space 16 of the turret 5 from a crew space 17. the crew space 17 can be part of the interior space 3, wherein the crew space 17 is arranged within the turret 5, however. The bulkhead 15 has a first surface 18 facing the ammunition compartment 16 and a second surface 19 facing the crew compartment 17. The surfaces 18, 19 are facing away from each other. A door opening 20 penetrates the bulkhead 15 so that the crew compartment 17 is accessible from the ammunition compartment 16 or vice versa. The sliding door module 14 can be used to close and open the door opening 20.The sliding door module 14 is assigned a coordinate system having 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 one another. This coordinate system of the sliding door module 14 does not have to coincide with the aforementioned coordinate system of the vehicle 1. Depending on the orientation of the sliding door module 14 relative to the vehicle trough 2, however, the two coordinate systems can also coincide or be identical.The sliding door module 14 has a sliding door 21. The sliding door 21 is plate-shaped. The sliding door 21 has a rectangular geometry. For example, the sliding door 21 is a rebar. However, the sliding door 21 may be made of aluminum alloy. Fiber composites can also be used. The sliding door 21 has a front side or first surface 22 facing the ammunition compartment 16 and a rear side or second surface 23 facing the crew compartment 17.The sliding door 21 can be moved from an open state Z 1 shown in FIGS. 2 and 4, in which the doorway 20 is released, so that the crew room 17 is accessible from the ammunition room 16 or vice versa, into a closed state Z 2 shown in FIG. 3, in which the sliding door 21 covers the doorway 20. In the closed state Z 2, the sliding door 21 is sealed in a gas-tight manner.In order to move the sliding door 21 from the open state Z 1 to the closed state Z 2, the sliding door 21 is moved linearly or translationally along a movement direction 24. The direction of movement 24 corresponds to the x-direction x or is arranged parallel thereto. In order to move the sliding door 21 from the closed state Z 2 into the open state Z 1, the sliding door 21 is moved counter to the direction of movement 24.The sliding door 21, in particular at least the first surface 22 of the sliding door 21, is inclined at an angle of inclination α relative to the direction of movement 24. The angle of inclination α is illustrated in FIG. 4 as an angle spanned between the direction of movement 24 and an auxiliary straight line 25 which runs parallel to the sliding door 21, in particular parallel to the first surface 22 of the sliding door 21. The surfaces 22, 23 are spaced apart from and parallel to each other. Also, the second surface 23 of the sliding door 21 may be inclined at the inclination angle α relative to the moving direction 24. However, this is not absolutely necessary.The inclination angle α is acute or an acute angle. The fact that the angle of inclination α is "acute" or an "acute angle" is to be understood here in particular as meaning that the angle of inclination α is less than 90°. The angle of inclination α is preferably 7° to 15°, more preferably 8° to 14°, more preferably 9° to 13°, more preferably 10° to 12°, more preferably exactly 11°.The inclination angle α is negative or a negative angle. The fact that the angle of inclination α is "negative" or a "negative angle" is to be understood in the present case in particular as meaning that the angle of inclination α results from a clockwise rotation or a clockwise rotation of the auxiliary straight line 25 with respect to the direction of movement 24. In contrast, a "positive angle" would be understood to mean an angle of inclination of the auxiliary straight line 25 with respect to the direction of movement 24, which angle of inclination results from a left-hand rotation or a counterclockwise rotation of the auxiliary straight line 25 with respect to the direction of movement 24.The x-direction x and the z-direction z span a plane 26. The direction of movement 24 lies in the plane 26. The auxiliary straight line 25 is inclined at the angle of inclination α relative to the plane 26. Accordingly, the sliding door 21, in particular the first surface 22 of the sliding door 21, is also inclined at the inclination angle α relative to the plane 26. In this case, the first surface 22 of the sliding door 21 forms a plane 27 which is arranged inclined at the angle of inclination α relative to the plane 26. In particular, the sliding door 21, in particular the first surface 22 or the plane 27, is rotated out of the plane 26 about the z-direction z or about an axis running parallel to the z-direction z.In addition to the sliding door 21, the sliding door module 14 comprises a guide device 28 on which the sliding door 21 is guided in a linearly displaceable manner along the direction of movement 24 in order to move the sliding door 21 from the open state Z 1 into the closed state Z 2 and, counter to the direction of movement 24, from the closed state Z 2 into the open state Z 1.The guide device 28 has an upper linear guide 29 and a lower linear guide 30 arranged at a distance from the upper linear guide 29 along the z-direction z. When viewed along the direction of gravity g, the lower linear guide 30 is placed below the upper linear guide 29. Viewed along the z-direction z, the sliding door 21 is arranged between the two linear guides 29, 30. The sliding door 21 is linearly guided along and counter to the direction of movement 24 on the two linear guides 29, 30.The linear guides 29, 30 extend along the direction of movement 24 or along the x-direction x. The linear guides 29, 30 can be designed as C profiles with a C-shaped cross section. Accordingly, the linear guides 29, 30 can each have a slot-shaped opening 31, 32 on the front side in the orientation of FIGS. 2 to 4. The linear guides 29, 30 do not run completely around the door opening 20 and thus do not form a closed frame. The sliding door module 14 is thus frameless or frameless.The sliding door 21, in particular the first surface 22 of the sliding door 21, is oriented at an angle of inclination α obliquely to the upper linear guide 29 and obliquely to the lower linear guide 30. In particular, the sliding door 21, preferably the first surface 22 of the sliding door 21, is inclined obliquely with respect to front surfaces 33, 34 of the linear guides 29, 30. The front surfaces 33, 34 are facing away from the bulkhead 15 and lie in a common plane 35. the plane 35 runs parallel to the plane 26.The guide device 28 further comprises a support plate 36 which supports the linear guides 29, 30. For example, the linear guides 29, 30 are screwed to the support plate 36. The support plate 36 may be a steel plate. The support plate 36 is firmly connected to the bulkhead 15. For this purpose, the support plate 36 can be screwed to the bulkhead 15. The support plate 36 has a door opening aperture 37 which coincides with the door opening 20. Furthermore, the support plate 36 has a further aperture 38. The door opening aperture 37 and the aperture 38 are arranged between the two linear guides 29, 30. Viewed along the x-direction x, the door opening aperture 37 and the aperture 38 are placed next to one another, wherein a strut-shaped section 39 of the supporting plate 36 is arranged between the door opening aperture 37 and the aperture 38.The support plate 36 carries a seal 40 of the sliding door module 14, and the seal 40 has a front or first sealing surface 41 against which the second surface 23 of the sliding door 21 abuts in the closed state Z 2 of the sliding door 21. The seal 40 completely surrounds the door opening aperture 37. The seal 40 is thus frame-shaped. The first sealing surface 41 is arranged parallel to the second surface 23 of the sliding door 21, which may be inclined at the inclination angle α. Accordingly, the first sealing surface 41 may also be inclined at the inclination angle α relative to the movement direction 24. The first sealing surface 41 lies in particular in a plane 42 which is inclined at the angle of inclination α relative to the plane 26.The seal 40 rests with a rear or second sealing surface 43 on the support plate 36. The seal 40 is wedge-shaped in cross section, so that the first sealing surface 41 is positioned inclined at the angle of inclination α relative to the second sealing surface 43. The seal 40 is made of an elastic material such as rubber or polyurethane. In the closed state Z 2 of the sliding door 21, the sliding door 21 rests with its second surface 23 against the first sealing surface 41, so that the seal 40 is pressed between the sliding door 21 and the support plate 36 in the closed state Z 2. The seal 40 seals the sliding door 21 in a gas-tight manner.Two upper guide slides 44, 45 are assigned to the upper linear guide 29 and can be moved along and counter to the direction of movement 24 along the upper linear guide 29. Each upper guide slide 44, 45 can be assigned a plurality of rollers or sliding elements which are arranged within the upper linear guide 29. In particular, a first upper guide slide 44 and a second upper guide slide 45 are provided. The upper guide slides 44, 45 are part of the guide device 28.Two lower guide slides 46, 47 are assigned to the lower linear guide 30, which slides can be moved along and counter to the direction of movement 24 along the lower linear guide 30. Each lower guide slide 46, 47 can be assigned a plurality of rollers or sliding elements which are arranged within the lower linear guide 30. In particular, a first lower guide slide 46 and a second lower guide slide 47 are provided. The lower guide slides 46, 47 are part of the guide device 28.The sliding door 21 is operatively connected or coupled indirectly to the guide device 28 by means of two upper coupling elements 48, 49 via the upper guide slides 44, 45. The upper coupling elements 48, 49 can be welded to the sliding door 21, in particular to the first surface 22 of the sliding door 21. A first upper coupling element 48 is provided, which is connected, in particular screwed, to the first upper guide slide 44. Furthermore, a second upper coupling element 49 is provided, which is connected, in particular screwed, to the second upper guide slide 45. The upper coupling elements 48, 49 are detachably connected to the upper guide slides 44, 45 with the aid of upper quick release elements 50, 51, for example in the form of screws.The sliding door 21 is furthermore operatively connected or coupled indirectly to the guide device 28 by means of two lower coupling elements 52, 53 via the lower guide slides 46, 47. The lower coupling elements 52, 53 may be welded to the sliding door 21, in particular to the first surface 22 of the sliding door 21. A first lower coupling element 52 is provided, which is connected, in particular screwed, to the first lower guide slide 46. Furthermore, a second lower coupling element 53 is provided, which is connected, in particular screwed, to the second lower guide slide 47. The lower coupling elements 52, 53 can be detachably connected to the lower guide slides 46, 47 with the aid of lower quick release elements 54, 55, for example in the form of screws.The lower quick release elements 54, 55 are optional. By releasing the upper quick release elements 50, 51, the sliding door 21 can be manually separated from the upper guide slides 44, 45 and disconnected from the guide device 28. In this case, the lower guide slides 46, 47 and / or the lower coupling elements 52, 53 are configured such that the sliding door 21 can be disconnected from the lower linear guide 30. In this case, the force of gravity can be used to disassemble the sliding door 21.In the event that the lower quick release elements 54, 55 are also provided, these can also be released in order to separate the sliding door 21 from the guide device 28. This can be advantageous, for example, in an emergency in order to be able to open the door opening 20. Alternatively, only the lower quick release elements 54, 55 can be provided, which can then be released accordingly in an emergency. Instead of screws, any other quick-release fasteners can be used as quick-release elements 50, 51, 54, 55.The sliding door module 14 further comprises a drive 56 connected to the guide device 28 for moving the sliding door 21 from the open state Z 1 to the closed state Z 2 and vice versa. The sliding door module 14 can have a plurality of drives 56. However, only one drive 56 is referred to below. The drive 56 can be an electric motor, in particular a rotary electric motor or a linear drive. In particular, the drive 56 is a servomotor or servomotor. In the case that the drive 56 is a linear drive, it can be integrated into one of the linear guides 29, 30. Such a drive 56 can also be integrated into each of the two linear guides 29, 30. The drive 56 can also be a hydraulic drive or a pneumatic drive.In the present example, the drive 56 is placed outside the linear guides 29, 30. For example, the drive 56 is coupled to the lower linear guide 30. The drive 56 is operatively connected to the lower guide slides 46, 47, for example, in order to move the latter along and counter to the direction of movement 24 along the lower linear guide 30. For this purpose, for example, a belt drive or a pinion and a toothed rack or the like can be provided. A force transmission from the lower guide slides 46, 47 to the sliding door 21 takes place via the lower coupling elements 52, 53 and optionally via the lower quick release elements 54, 55, in order to move the latter with the aid of the drive 56 from the open state Z 1 into the closed state Z 2 and vice versa.Only a guidance of the sliding door 21 then takes place on the upper linear guide 29, but as mentioned above, such a drive 56 can also be assigned to the upper linear guide 29. In this case, the sliding door 21 is then driven both on the upper linear guide 29 and on the lower linear guide 30. The drive 56 can be firmly connected to the lower linear guide 30 and / or to the support plate 36. A screw connection can be provided, for example. The drive 56 is part of the guide device 28.The sliding door module 14 further comprises a brake 57 for braking the sliding door 21 when the sliding door 21 is moved from the open state Z 1 into the closed state Z 2 and / or vice versa. The brake 57 is part of the guide device 28. The brake 57 may be an eddy current brake. However, the brake 57 may be a friction brake. The brake 57 can be integrated into the drive 56 or can be mounted on the drive 56. However, this is not absolutely necessary. The brake 57 can also be integrated into one or both of the linear guides 29, 30.A housing 58 is assigned to the sliding door module 14. The housing 58 can be fixedly connected to one or both of the linear guides 29, 30 and / or to the support plate 36. The housing 58 can also be supported on the drive 56 or enclose the drive 56 at least in sections. A control unit 59 of the sliding door module 14 is accommodated in the housing 58. The drive 56 and / or the brake 57 can be activated with the aid of the control unit 59 in order to move the sliding door 21 from the open state Z 1 into the closed state Z 2 and vice versa.The control unit 59 is preferably an analog circuit or comprises an analog circuit. This makes the control unit 59 insensitive to faults, so that the sliding door 21 can be closed and / or opened, for example, even in the event of a failure of onboard electronics of the vehicle 1. However, this is not absolutely necessary. The control unit 59 may also include a computer or the like. The control unit 59 can be part of the guide device 28.Further, an emergency power supply 60 of the sliding door module 14 is accommodated in the housing 58. With the aid of the emergency power supply 60, the drive 56 and / or the control unit 59 can be energized, for example, in the event of a failure of an on-board power supply of the vehicle 1, in order to close and / or open the sliding door 21. The emergency power supply 60 may include one or more accumulators. With the aid of the emergency power supply 60, autonomous operation of the sliding door module 14 is possible in an emergency. The emergency power supply 60 can be part of the guide device 28.The sliding door module 14 further comprises a movement range monitoring device 61 for monitoring a movement range 62 of the sliding door 21, and damage to the crew by the moving sliding door 21 can be reliably prevented by means of the movement range monitoring device 61. In the moving range 62, the slide door 21 moves when moving it from the opened state Z 1 to the closed state Z 2, and vice versa. The movement range monitoring device 61 provides sensor signals to the control unit 59. The sensor signals may include a respective position of the sliding door 21. A data connection can be provided between the movement range monitoring device 61 and the control unit 59. This data connection can be wireless or wired.The movement range monitoring device 61 can have a first light barrier 63 and an optional second light barrier 64, which are each arranged at the end side of the movement range 62. The support plate 36 carries the light barriers 63, 64 Reflectors can be associated with the light barriers 63, 64. The second light barrier 64 can be dispensed with. The movement range monitoring device 61 can be part of the guide device 28. Instead of the light barriers 63, 64, the range of movement monitoring 61 can have any other sensors, for example capacitive and / or inductive sensors. Furthermore, the movement range monitoring device 61 can have one or more cameras 65 for monitoring the movement range 62. The camera 65 may be mounted on the support plate 36 (not shown). The light barriers 63, 64 are preferably analogous light barriers.The sliding door module 14 further comprises an end position monitoring device 66 for monitoring end positions of the sliding door 21 in the open state Z 1 and / or in the closed state Z 2. The end position monitoring means 66 can be part of the guide device 28. For example, the end position monitoring device 66 can have a first end position sensor 67 which is associated with an end position of the sliding door 21 in the open state Z 1 and a second end position sensor 68 which is associated with an end position of the sliding door 21 in the closed state Z 2.The end position sensors 67, 68 can be mounted on the support plate 36. More than two end position sensors 67, 68 can be provided. The end position sensors 67, 68 can be switches, optical sensors, inductive sensors, capacitive sensors or the like, for example. The end position monitoring system 66 provides sensor signals to the control unit 59. The sensor signals can comprise a respective position of the sliding door 21 in its respective end position. A data connection can be provided between the end position monitoring means 66 and the control unit 59. This data connection can be wireless or wired.The sliding door module 14 can furthermore have lifting means 69, 70, of which only two are shown in FIGS. 2 and 3. The lifting means 69, 70 may be lifting eyes. By means of the lifting means 69, 70 it is possible to lift and transport the sliding door module 14, for example by means of a hall crane, as a compact unit. The lifting means 69, 70 can be mounted on the support plate 36 and / or on the upper linear guide 29. The lifting means 69, 70 can be removed from the sliding door module 14 after the assembly of the latter has been completed. The lifting means 69, 70 can, however, also be left on the sliding door module 14.The functionality of the sliding door module 14 is explained below. As mentioned above, the sliding door module 14 is mounted on the bulkhead 15 of the turret 5 arranged between the ammunition compartment 16 and the crew compartment 17. The sliding door module 14 is arranged on the first surface 18 of the bulkhead 15 facing the ammunition compartment 16 and thus within the ammunition compartment 16.In the ammunition room 16 there is cartridge ammunition or patronized ammunition 71 for the weapon 6. For example, twenty pieces of patronized ammunition 71 are in the ammunition room 16. Furthermore, an automatic loader 72, for example comprising a robot, is arranged in the ammunition chamber 16, which is suitable for feeding a respective piece of the patronized ammunition 71 through the doorway 20 of the bulkhead 15 to a cartridge store 73 of the weapon 6.The sliding door 21 is initially in the closed state Z 2. If loading of the weapon 6 is now required, the automatic loader 72 keeps a piece of patronized ammunition 71 ready. The slide door 21 is moved from the closed state Z 2 to the open state Z 1, thereby releasing the door opening 20. The opening of the sliding door 21 can take less than 0.5 seconds, for example. The same applies to the closing of the sliding door 21 The automatic loader 72 has a high degree of kadence. This high degree of carcass requires the sliding door 21 to open and close very quickly and, in the closed state Z 2, offer a high degree of protection for crew in the crew room 17. In addition, a high level of functional reliability is required.The moving of the sliding door 21 from the closed state Z 2 into the open state Z 1 and vice versa can be effected by the crew, for example by giving a corresponding command to the control unit 59 for opening or closing the sliding door 21. In the simplest case, this can be effected, for example, by actuating a switch arranged in the crew room 17. However, the opening and closing of the sliding door 21 can also be automated. Particularly preferably, the sliding door 21 is opened and closed automatically with the aid of a direct signal and / or an indirect signal of the automatic loader 72.Once the sliding door 21 is in the open state Z 1, the automatic loader 72 reaches the pattroned ammunition 71 through the doorway 20 into the cartridge store 73 and then retracts into the ammunition compartment 16. As a result, the crew in the crew room 17 is protected even when the ammunition room 16 suffers, for example, a hit which leads to an explosion of the patronized ammunition 71.The oblique position of the sliding door 21 at the angle of inclination α ensures that a pressure wave 74 resulting from a hit in the ammunition compartment 16 presses the sliding door 21 in the direction of the closed state Z 2. The pressure shaft 74 may also be referred to as a blast or an explosion blast. The pressure shaft 74 can therefore not press open the sliding door 21 and thus bring it into the open state Z 1. Rather, the pressure shaft 74 presses the sliding door 21 against the seal 40 and via the coupling elements 48, 49, 52, 53 against the linear guides 29, 30.Due to the inclination of the sliding door 21 at the inclination angle α, the pressure wave 74 acting on the sliding door 21 results in a closing force F oriented along the direction of movement 24. the closing force F either moves the sliding door 21 in the direction of the closed state Z 2 or assists this movement along the direction of movement 24 or presses the sliding door 21, when the sliding door 21 is already in the closed state Z 2, against the seal 40 and / or the linear guides 29, 30.The sliding door 21 thus reliably separates the crew compartment 17 from the ammunition compartment 16. The crew is thereby reliably protected. A respective closing and opening time is preferably below 0.5 seconds, which further increases the safety for the crew. The sliding door 21 is very massive and serves to protect the crew from an unintentional explosion of the pattroned ammunition 71 The closing and opening of the sliding door 21 is preferably carried out completely without software. As mentioned above, the sliding door module 14 is thereby particularly trouble-free and robust.The movement range monitoring device 61 ensures that no objects or crew members are caught by the sliding door 21. Before a collision occurs, the slide door 21 is stopped by the brake 57. The linear guides 29, 30 are connected to one another only by means of the sliding door 21. A frame or door frame for the sliding door 21 is not provided. The guide device 28 can be bypassed by dismantling the sliding door 21, in which case the upper quick release elements 50, 51 and / or the lower quick release elements 54, 55 can optionally be removed. The sliding door 21 can thus be manually unlocked by emergency. The quick release elements 50, 51, 54, 55 are not relevant for the protective effect of the sliding door module 14, since the pressure shaft 74 presses the sliding door 21 against the seal 40 and / or the linear guides 29, 30 from the direction of the ammunition compartment 16. The quick release elements 50, 51, 54, 55 are therefore not mechanically loaded by the pressure shaft 74.Because of the emergency power supply 60, the drive 56, the brake 57 and / or the control unit 59 can be supplied with energy if necessary. Even in the event of a complete failure of the sliding door module 14, the protective effect of the sliding door 21 is still maintained. Even in the event that one of the guide slides 44, 45, 46, 47 jams, it can be optionally decoupled from the sliding door 21. This is done with the aid of the quick release elements 50, 51, 54, 55.The inclination of the sliding door 21 at the inclination angle α achieves the following advantages. Since the seal 40 is not touched by the sliding door 21 until the closed state Z 2 is reached or immediately before the closed state Z 2 is reached, the friction in the remaining movement region 62 is reduced. This allows the sliding door 21 to have a short closing and opening time of less than 0.5 seconds.In the event of an explosion in the ammunition chamber 16, the sliding door 21 is pushed by the oblique position in the direction of the closed state Z 2. This increases safety by additional safety against closure. Furthermore, the oblique position increases a path through which flying fragments must travel through the sliding door 21. This helps to be able to better repel the fragments and thus further increases the safety for crew.The direct mounting of the control unit 59 next to the sliding door 21 allows a short cable routing, which in turn leads to a higher dynamic response of the sliding door 21. The use of short cables also keeps the power loss and the weight low and also increases the electromagnetic safety of the sliding door module 14.By detecting the end positions of the sliding door 21 by sensor using the end position monitoring 66, the operational reliability is increased and it is ensured that end stops of the sliding door 21 are not overloaded. Moreover, the limit stops provided with the limit position sensors 67, 68 allow the accurate position of the sliding door 21 to be detected, and thereby a control cam of the drive 56 can be adjusted more accurately, which brings about another advantage in relation to the closing and opening speed of the sliding door 21.The preferred use of analog light barriers 63, 64, which is not connected to a microcontroller and / or a complex controller, for the movement range monitoring 61 provides advantages with regard to operational reliability, manipulation safety, in particular dynamics and detection speed. In addition, the decoupling of processors and the electronic simplexity have a positive effect on the electromagnetic safety and / or the cyber safety of the sliding door module 14.In summary, the sliding door module 14 thus has a high dynamic, good maintainability, a high low maintenance demand, a high level of safety against effects of mechanical, electromagnetic and detonic nature, a high level of operational safety, a low risk of injury, a high level of handling safety, a low level of complexity and cost-effective maintenance, in particular the possibility of simple replacement. Furthermore, the sliding door module 14 forms an independent system which also functions autonomously.FIG. 5 shows a schematic sectional view of an embodiment of a sealing arrangement 75 for the sliding door module 14.The sealing arrangement 75 can be used as an alternative to the seal 40 explained above for sealing the sliding door 21. The seal assembly 75 includes a seal 76 and a support 77 that supports the seal 76. The carrier 77 can be manufactured, for example, from a steel alloy or from an aluminum alloy. The seal 76 is elastically deformable. For example, the seal 76 is made of rubber or polyurethane.The carrier 77 is wedge-shaped in cross-section and includes a front or first surface 78 and a rear or second surface 79 remote from the first surface 78. The second surface 79 of the support 77 can rest against the support plate 36. The first surface 78, like the first sealing surface 41 of the seal 40, is inclined at the angle of inclination α relative to the direction of movement 24 or the plane 26. The second surface 79 is oriented parallel to the plane 26. The first surface 78 is thus inclined at the inclination angle α relative to the second surface 79. The bracket 77 has an opening 80 which coincides with the door opening opening 37 of the supporting plate 36.The support 77 can be screwed, riveted and / or welded to the support plate 36. The support 77 can also be part of the support plate 36. In this case, the carrier 77 and the support plate 36 can form a one-piece component, in particular a component of one piece of material.The seal 76 comprises a first sealing surface 81 and a second sealing surface 82 facing away from the first sealing surface 81. With the second sealing surface 82, the seal 76 abuts the first surface 78 of the carrier 77. In the closed state Z 2, the sliding door 21 rests with its second surface 23 against the first sealing surface 81. The two sealing surfaces 81, 82 extend parallel to one another. The first sealing surface 81 lies in a plane 83 which, like the plane 42 of the seal 40, is inclined at the angle of inclination α obliquely to the direction of movement 24 or the plane 26. The first sealing surface 81 is thus also inclined at the angle of inclination α obliquely to the direction of movement 24 or the plane 26.Unlike the seal 40, however, the seal 76 is not wedge-shaped in cross section, but is preferably rectangular. The seal 76 completely surrounds the aperture 80 or the door opening aperture 37. In cross section, the seal 76 can have basically any desired geometry, for example a rectangular, oval, circular or triangular geometry. The seal 76 can also be a round seal, in particular a sealing cord.
