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 The invention relates to a lafette for a gun, wherein a capped, across from a carrier vehicle Elevating Gun barrel is slidably mounted in a cradle.

Large caliber Pipe weapons are used either in main battle tanks, where usually the weapon is aimed directly at the target while driving (direct directing), or in artillery systems, e.g. in armored howitzers, used, in which an indirect judging of the weapon takes place from the state, because the target is hidden. According to the different straightening methods the weapon in battle tanks and artillery systems becomes the weapon in both systems differently lafettiert. It makes a difference the Lafettierung particular in the arrangement of the trunnion axes to which the elevation movement accomplished becomes. So is the maximum increase for armored weapons about 20 °, while Artillery weapons with an increase fire up to 70 °.

At the Main battle tank, it is advantageous to the trunnion near the center of gravity the elevatable Mass, because otherwise from the weapon tracking system, especially at high speeds, i. big vertical accelerations, size Stellmomente would apply, which would lead to heavier actuators. In contrast, is the trunnion of an artillery weapon relative to the center of gravity of höhenrichtbaren Mass shifted far in the direction of the bottom piece (lock), to the height of the gun preferably to keep low and even with large increases long return paths to enable. Since only statically directed, the Höhenrichtantrieb can by a compensator from the relatively large one Unbalance moment be relieved.

Of the Invention is the object of a Lafettierung for a gun of a armored carrier vehicle specify with the optional direct or indirect straightening / firing the weapon can be done.

These The object is achieved by the Characteristics of claim 1 solved. Further, particularly advantageous embodiments of the invention reveal the dependent claims.

The Invention is based essentially on the idea of the trunnion axes so at the cradle of the gun to arrange that respective gun barrel of the gun alternatively height-adjustable by two different trunnion axes is, wherein the first trunnion axis in the vicinity of the center of gravity of the höhenrichtbaren Mass of the gun and the second trunnion axis opposite the first trunnion axis is arranged shifted in the direction of the closure. Detachable fastening devices to fix the trunnion axes act against a shift relative to the carrier vehicle, So that the respective trunnion axis about which the weapon barrel is pivotable, not with respect to the host vehicle can be moved.

The direct straightening while driving then takes place around the focal point Shield pin axis while for artillery combat a target the weapon from the stand to the near-ground axis is directed.

The inventive Lafettierung is particularly advantageous for air-powered combat vehicles, where previously transported two different weapon systems had to so that the logistic effort especially at a fast and worldwide Use of appropriate guns across from halved previous systems.

at a first embodiment The invention provides that the elevation movement of the gun barrel by two separate straightening drives, each with a first joint with the cradle in the area of the trunnion axes and over one second joint with the carrier vehicle are connected.

Further Details and advantages of the invention will become apparent from the following explained with reference to figures Embodiments. Show it:

1 a schematic side view of a Lafettierung invention with an attached gun barrel and

2 a section through a trunnion bearing with a fastening device for fixing a trunnion axis.

In 1 is with 1 one on an armored carrier vehicle 2 arranged gun indicated. The gun 1 includes one with a closure 3 provided weapon barrel 4 in a cradle 5 is slidably mounted. This is the barrel 4 when shooting against the weft direction along the axis of the soul 110 of the barrel 4 in camps 6 . 7 the cradle 5 guided. During the return are the through the barrel 4 and the closure 3 given returning masses by a braking device 8th decelerated, wherein the braking forces via the braking device 8th on the cradle 5 be transmitted.

At the cradle 5 are two trunnion axles 9 . 10 provided, wherein the first trunnion axis 9 near the center of gravity 11 the höhenrichtbaren mass is located and the second trunnion axis 10 opposite the first trunnion axis 9 in the direction of the closure 3 is arranged shifted.

If a direct aiming of the weapon is now to be carried out, the pivoting movement takes place for height alignment about the first trunnion axis 9 , This axis 9 is in this case against displacements relative to the carrier vehicle 2 fixed so that recoil forces over the first trunnion axis 9 from the cradle 5 in the carrier vehicle 2 be directed. The Höhenrichtbewegung is thereby from a corresponding first directional drive 12 generated by a first joint 13 with the cradle 5 and a second joint 14 with the carrier vehicle 2 connected is.

If the weapon is to be directed indirectly, then the first joint 13 opposite the carrier vehicle 2 fixed in the position that allows for the largest direct increase directing. The fixation of the first trunnion axis 9 opposite the carrier vehicle 2 will be solved afterwards. The axis 10 now assumes the function of a trunnion axis, around which the weapon is aimed in height and on which the recoil forces from the cradle 5 in the carrier vehicle 2 be directed. The Höhenrichtbewegung generated in indirect straightening a second directional drive 15 who has a first joint 16 with the cradle 5 and a second joint 17 with the carrier vehicle 2 connected is.

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

Of course, the invention is not limited to the embodiment described above. So have the straightening drives 12 . 15 not necessarily in the area of the trunnion axes 9 . 10 with the cradle 5 but can 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.
