The invention relates to an articulated armored or armored wheeled vehicle with a central space and the preferential installation of a gun.

It is designed in particular to repel attacks by tank formations.

The past Middle East wars have made it increasingly clear that the defense against attacking tank units with the same means, i.e. with more or less equivalent battle tanks, for the moment can lead to success, any army reverses its substance within a few days with great certainty to conduct one's own massed counter-attacks in immediate reaction, i.e. out of the situation, takes. The replacement, if there is one, must be brought in from the depths of the staging rooms.

The use of battle tanks against battle tanks is therefore not militarily sensible. This teaching was however not only given by the past Middle East wars, but it was made on a large scale by the The course of the tank battle in Barely Orel - Belgorod in 1943 was practically mapped out for the future,

This resulted in the development of special defensive weapons in further development of the adhesive shaped charges (Panzerfaust or the like.) As well as that of anti-missile missiles, especially in the USA and in the Soviet Union are reflected in modern systems according to the level of the SAM.

Just the use of this weapon system has confirmed that with an effort of a five hundredth to three hundredths compared to the cost

of a modern main battle tank, achieves the same effect without endangering the team.

The development of suitable armor-piercing, highly mobile defensive weapons is therefore a priority. The modern ones However, today's systems require extensive installation (Suez Canal) and are in use not very mobile. This in turn means the more or less exact forecast of the opposing action.

It is therefore not surprising in this context if today the deliberations return to the aimed shot, i.e. the anti-tank gun, certain opportunities grant. Not only is it relatively cheap, it is also uncomplicated in every way.

If one looks at the individual historical stages of the development of the anti-tank gun, then there are once In addition to the normal field guns, the anti-tank gun developed in the early 1930s, the 8, 8 or 10.5 Flak cannon on spreader mounts and the various cannons on self-propelled guns received a critical appreciation to undergo.

The anti-tank and anti-aircraft guns gave the projectiles a high "V-NuIl" and thus a higher level than the usual ones Guns this time increased penetration. They have proven to be excellent armor-piercing weapons proven. However, their limited mobility led to their self-propelled carriage, which in turn was dated Wheeled vehicle via the wheel-tracked vehicle to the pure tracked vehicle and ultimately to the battle tank itself led.

The end of this development ended in the situation outlined at the beginning.

Determining the direction for this somewhat unfortunate development was the lack of cross-country mobility and other suitability of the wheeled vehicles, since the steering systems do not have sufficient mobility and on the other hand, the state of the art of tire development only enabled the development of vehicles whose ground pressure is much higher than that of tracked vehicles.

Only advances in tire technology, in particular the development of large-volume low-pressure radial tires, as they were first brought onto the market by the Michelin company and especially in construction machine technology have found widespread use, as well as the advances · ΐη of articulated handlebar technology, such as those for example by DT-OS 2 239 732, have again the inclusion of wheeled vehicles in made the considerations regarding the selection of carriers for anti-tank weapons interesting again.

The latest state of tire development offers a good safeguard against the effects of small calibres Infantry bullets. If the tire is destroyed by splinters or the like, appropriate training the rim still has limited emergency running properties.

The centrally-steered articulated handlebar already offers a number of advantages compared to its design the usual four-wheel vehicle, which this conventional conception for the future on the military Exclude sector.

Among other things, the driving behavior is the same when driving forwards and backwards thanks to symmetrical steering geometry Always given in both directions. Allow the pivotability of the two car parts a much smaller curve radius and thus enables optimal maneuverability in the field.

The list of advantages is not exhaustive and it is only intended to be the basis of the tasks to be set its content is an armored or armored articulated wheeled vehicle with pneumatic tires to represent the steering and direction of the weapon starting from a central area, in the simplest possible way is feasible using and further training the given options.

The invention provides that the articulation axis through the axes of two mutually guided, mutually fixing, mutually rotatable bodies is formed, each of which has a chariot part, either the chariot part or the marching wagon part is connected, both wagon parts are equipped with wheels, whereby the height of the individual wheels from a separately adjustable zero position out arbitrarily and independently are adjustable from each other, and that the space of the inner body to accommodate part of the crew and the main control device for the vehicle and the movement of the weapon and its storage is, and that regardless of whether the combat part or the march part points in the direction of travel, the same Steering and drive mechanisms are given.

The design of this vehicle shows, in addition to the advantages mentioned, the same driving behavior Forward and backward travel, the greater maneuverability and better off-road mobility the advantage of all

509B82 / 059 _8/6

essential controls are located in the inner body and these parts are given additional protection.

By setting the zero position in different height ranges and the independent setting option the single wheels can rigidly build the weapon or its mount in the inner body and directed by the movement of the car parts towards each other around the articulation axis, connected with the wheel setting will.

This eliminates the need for a separately rotatable turret.

The mutually rotatable bodies are two cylinders or partial cylinders that are guided into one another are closed at the bottom by calotters or arched floors.

The choice of a cylindrical cross-section for the hollow body and its lower termination by a Arched floor not only has the advantage of optimal use of space, but also that of an extremely static one Strength as well as a strong deflection in the event of weapon impact on the ground.

The intended installation of a weapon, preferably one Gun, takes place in the closed inner cylinder and the combat part connected to it in the upper one Cover this cylinder firmly and is with the steering of the vehicle around the articulation axis and perpendicular to this Can be swiveled to each side by at least 60 ° from the central position.

Due to the storage of the weapon directed towards the center of gravity, it is possible that the return of the pipe in its

509882/0598 / ⁷

16/6/74 ". - 7 -

Guidance outside the inner cylinder, i.e. the central cylinder, can take place.

The gun is about the diameter of the central cylinder additionally supported on a support attached to the fighting part of the vehicle, what interacts with the storage in the center of gravity, allows a large caliber length, since there is a risk of "sagging", i.e. that of the pipe being deformed is reduced to a minimum.

The swiveling of the parts is done by the articulation axis to each other, the setting of the zero position and, based on this, the independent setting of the wheels from one another is advantageously carried out by a central control organ. This control body can be used in training, Arrangement and effect correspond to that of an airplane.

It is also provided that a pressurized gas generator and / or a pressurized gas container with an associated central control valve for individual or total positive or negative pressure change in the tires of the Wheels via pipes and arm doors leading to the wheels.

It should be noted that the normally open a ground pressure of 0.8 kg / cm if there is a risk of getting stuck or sinking in Self-liberation can be lowered. Due to the increasing contact area, the transferable force on the ground significantly increased, so that here real advantages over a tracked vehicle given are. After the so-called self-liberation, the gas pressure in the tire can rise again raised to its normal height so that the vehicle can be driven again at the appropriate speed.

Modifications to the vehicle provide that the cover of the central cylinder is movable Spherical cap is that carries the weapon. This is another component for quick weapon elevation given.

With heavy training of the vehicle, it is provided that instead of two pairs of wheels four or several pairs of wheels are arranged in a box-shaped manner.

For stabilization, it is provided that the cylinders are guided into one another by a slewing ring, whereby the turntable is directed upwards in the main battle direction by a few degrees from the horizontal is.

By this arrangement, the chariot part receives an increased load when buckling, so that a greater stability of the vehicle is given at high speed and rapid steering angles.

In summary, there are the following advantages in addition to the advantages already mentioned:

1. The central cylinder system allows almost * the same visibility to the front and rear.

2. The central cylinder system allows large inclined surfaces and thus an optimal ratio of armored area to protected interior space.

3. The independent wheel suspension in wheel swing allows full utilization of the emergency running properties, whereby By eliminating the steering axles and the parallel guidance, the use of larger tires, both in Diameter and width, is made possible, whereby an increase in off-road capability is given.

4. The level control allows the setting of a large ground clearance, with in the raised position a good panoramic view, in the lowered position a low silhouette, so given a small target A better dissipation of the recoil impulses is achieved in the lower position.

The invention is explained in more detail by way of example by means of FIGS.

Figure 1 shows in elevation the armored or armored Articulated wheeled vehicle with central cylinder as well as the representation of the possible Weapon installation.

The weapon itself is the self-contained central inner cylinder, at the same time the combat-side wagon part is connected, assigned or whose carriage is firmly connected to this.

The jacket cylinder of the central cylinder system is a partial cylinder comprising the inner cylinder about 200, where this cylinder is the part of the carriage on the march side connected. This car part essentially takes the drive and hydraulic units for driving the Wheels whose level setting can be set to zero level, which can be set automatically together or individually differently, as well as the space for the ammunition deposit and for the load of the weapon, which is in the frame this example a relatively small-caliber gun with a long barrel length to achieve represents a high exit velocity for the projectile, on or on.

The gun construction is based on a projectile weight of about 7 kg, i.e. it is mainly intended for the defense against enemy tanks.

Figure 2 shows the vehicle in plan. From this representation is particularly the leadership of the Cylinders in one another, the intended position of the units as well as the ammunition and cargo space, which is shown in dashed lines in the marching-side wagon section.

The location of the hold shows that the gun has the entire pivoting range there is a good possibility of charging according to conventional methods and that there is also sufficient space for an automatic reloading device is given.

Furthermore, from Figure 2, the pivotability of the two car parts to each other to see. The combat-side wagon part can be converted to the march-side wagon part, i.e. pivot its longitudinal axis to each side by 60, so that a total pivoting range of the gun while maintaining the position of the marching-side wagon part of is given.

From the plan there is also the dashed line position of the so-called driver's plate within the central cylinder system to see. Usually this plate is in the direction of the combat-side part of the car fixed and is pivoted through 180 ° including the main control element when cruising .

Of course, two control elements offset by 180 ° can also be provided, so that only the seat has to be rotated.
