Abstract

A cradle (5) has spaced shield cone axles (9,10) about which a weapon pipe (4) is elevatable. The axle (9) is proximate the center of gravity (11) of the cannon (1) while the axle (10) may be pushed towards and away from a catch (3). Fastening devices prevent adjustment of the shield cone axles relative to a carrier vehicle (2) such that the shield cone axles may not be pushed away.

Description

The invention relates to a Lafettierung for a gun, wherein a provided with a closure, with respect to a carrier vehicle höhenrichtbares weapon barrel is slidably mounted in a cradle.

Large caliber guns are used either in battle tanks, where the weapon is usually aimed directly at the target while driving (direct straightening), or in artillery systems, e.g. in armored howitzers, used in which an indirect aiming of the weapon takes place from the state, since the target is covered. According to the different straightening methods of the weapon in battle tanks and artillery systems, the weapon is lafettiert differently in both systems. In this case, the Lafettierung differs in particular in the arrangement of the trunnion axes about which the Höhenrichtbewegung is performed. Thus, the maximum increase in armored weapons is about 20 °, while artillery fire with an increase of up to 70 °.

In the main battle tank, it is advantageous to arrange the trunnion near the center of gravity of höhenrichtbaren mass, because otherwise would be applied by the weapon tracking system, especially at high speeds, ie large vertical accelerations, large actuation torques, which would lead to heavier actuators. In contrast, the trunnion of an artillery piece is moved relative to the center of gravity of the höhenrichtbaren mass far in the direction of the bottom piece (shutter) to keep the height of the gun as low as possible and to allow for large increases long return paths. Since only statically directed, the Höhenrichtantrieb can be relieved by a balancer from the relatively large unbalanced torque.

With the GB 521 205 A already an attachment or storage of a machine gun in an aircraft already described, so that the weapon is movable in the transverse and lateral directions. A direct or indirect shooting is not possible with such a connection and not even considered.

The DE 309 124 C concerns a gun carriage with two trunnion bearings. Each of these trunnion bearing pairs belongs to a specific type of pipe, such as steep-flamed gun or flat fire-proof. There is always only one pipe in the gun carriage. Depending on requirements, one tube can then be exchanged for the other.

The invention has for its object to provide a Lafettierung for a gun of an armored carrier vehicle, with the optional direct or indirect straightening / firing of the weapon can be done.

This object is achieved by the features of claim 1. Further, particularly advantageous embodiments of the invention disclose the dependent claims.

The invention is based essentially on the idea of arranging the trunnion axes on the cradle of the gun, that the respective gun barrel of the gun alternatively by two different trunnion axes höhenrichtbar, the first trunnion axis near the center of gravity of the höhenrichtbaren mass of the gun and the second Shield pin axis is arranged offset from the first trunnion axis in the direction of the closure. Detachable fastening means for fixing the trunnion axes act against displacement relative to the carrier vehicle so that the respective trunnion axis about which the weapon tube is pivotable can not be displaced with respect to the carrier vehicle.

The direct straightening during the ride then takes place around the axis of the trunnion axis, while the artilleristically combat a target, the weapon is aimed at the ground near the ground axis.

The Lafettierung invention is particularly advantageous for airborne combat vehicles in which previously had to be transported two different weapon systems, so that halves the logistical effort especially with a fast and worldwide use of appropriate guns over previous systems.

In a first embodiment of the invention, it is provided that the Höhenrichtbewegung of the gun barrel is effected by two separate straightening drives, which are each connected via a first joint with the cradle in the field of trunnion axes and a second joint with the carrier vehicle.

Further details and advantages of the invention will become apparent from the following Illustrated embodiments of embodiments. Show it:

• Fig.1 a schematic side view of a Lafettierung invention with an attached gun barrel and
• Fig.2 a section through a trunnion bearing with a fastening device for fixing a trunnion axis.

In Fig. 1 1 indicates a gun mounted on an armored carrier vehicle 2. The gun 1 comprises a provided with a closure 3 gun barrel 4, which is slidably mounted in a cradle 5. In this case, the gun barrel 4 is guided against the shooting direction along the axis of the shaft 110 of the weapon barrel 4 in camps 6, 7 of the cradle 5 during firing. During the return, the given through the gun barrel 4 and the shutter 3 returning masses are braked by a braking device 8, wherein the braking forces are transmitted to the cradle 5 via the braking device 8.

At the cradle 5, two trunnion axes 9, 10 are provided, wherein the first trunnion axis 9 is located in the vicinity of the center of gravity 11 of the höhenrichtbaren mass and the second trunnion axis 10 relative to the first trunnion axis 9 is arranged shifted in the direction of the shutter 3.

If a direct directing of the weapon is now to take place, the pivoting movement takes place for height alignment about the first trunnion axis 9. This axis 9 is fixed in this case against displacements relative to the carrier vehicle 2, so that repulsion forces on the first trunnion axis 9 of the cradle 5 in the carrier vehicle 2 are conducted. The Höhenrichtbewegung is generated by a corresponding first directional drive 12 which is connected via a first joint 13 with the cradle 5 and a second joint 14 with the carrier vehicle 2.

If the weapon is to be directed indirectly, then the first joint 13 is fixed relative to the carrier vehicle 2 in the position which allows the greatest increase for the direct straightening. The fixation of the first trunnion axis 9 relative to the carrier vehicle. 2 will be solved afterwards. The axle 10 now assumes the function of a trunnion axis about which the weapon is directed in height and over which the recoil forces are conducted from the cradle 5 in the carrier vehicle 2. When directed indirectly, the elevation movement produces a second leveling drive 15, which is connected to the cradle 5 via a first joint 16 and to the carrier vehicle 2 via a second joint 17.

The alternate fixing of the trunnion axes 9 and 10 relative to the carrier vehicle 2 is effected by fastening means 18. A corresponding fastening device for the fixation of the trunnion axis 9 is shown in FIG Fig.2 shown schematically.

Of course, the invention is not limited to the embodiment described above. Thus, the straightening drives 12, 15 need not necessarily be connected in the region of the trunnion axes 9, 10 with the cradle 5, but may also be connected in adjacent areas via corresponding joints with the cradle. Furthermore, it may also be sufficient to use only a single leveling drive, which engages, for example via a corresponding joint in the central region between the trunnion axes on the cradle.
