Definitions

the invention relates to an unbalance compensation device for a weapon system, in particular in the case of a heavy weapon, with a part which can be pivoted in the elevation direction and which carries the weapon barrel and is mounted in a fixed frame via a shield pin, the center of gravity of the pivotable part outside the axis of rotation of the shield pin is at which a torque counteracting the imbalance torque is generated by at least one spring.
At least one torsion bar spring serves as the spring, the first end of which is connected to the frame in a rotationally fixed manner, while the second end is connected to the pivotable part of the weapon via a gear.
the present invention aims to improve and further develop this older proposal.
the invention is based on the following considerations:
the torsion bar spring energy E FD available for imbalance compensation which is transmitted to the weapon by the transmission, is determined with the linear characteristic by the following equation:
c D torsional stiffness of the torsion bar spring
⁇ 1G torsion angle of the torsion bar with minimal elevation of the swiveling part of the weapon
⁇ 1V torsion angle of the torsion bar at maximum elevation of the swiveling part of the weapon.
the invention is based on the object, in a further development of the subject matter of the older proposal, to provide a simple possibility for storing further energy in order nevertheless to achieve an almost complete imbalance compensation.
the transmission has a lever which is connected in a rotationally fixed manner to the above-mentioned second end of the torsion bar spring and which is connected in an articulated manner to a spring strut articulated on the pivotable part of the weapon with at least one compression spring.
This compression spring can be designed to be prestressable by means of a stop and the deflection of this compression spring can be limited by a stop.
the torsion bar spring is arranged concentrically at least over part of its length in a protective tube rotatably mounted in the frame, one end of which is connected in a rotationally fixed manner to the second end of the torsion bar spring and that the transmission transmitting the rotary movement is connected to the protective tube.
the protective tube can itself be designed as a torsion bar spring.
the basic idea of the invention is to design further transmission elements in the transmission between the torsion bar spring and the weapon as spring elements, which store the energy which is missing for complete unbalance compensation.
Particularly advantageous, for example, in a four-bar transmission is the formation of the connection between the mist connected to the second end of the torsion bar spring and the pivotable part of the weapon as a further energy store in the form of a spring strut, the compression spring, for example in the case of a linear spring characteristic, taking into account the variable transmission ratio to adapt to the imbalance torque, must be designed such that the following energy equations are approximately fulfilled.
E FL absorbed energy of the connection designed as a compression spring with the smallest elevation of the weapon.
the weapon system in the turret of a main battle tank can be seen in a highly schematic representation, the weapon system depicting the tower 2 which forms the fixed frame, that is to say the mount, and the pivotable part 1 which consists of the weapon barrel and the cradle body.
the pivotable part 1 is pivotally mounted in the fixed frame 2 in the elevation direction via a shield pin 1.1 and can be pivoted by a directional drive 3.
a torsion bar spring 4 is arranged parallel to the axis of rotation of the shield pin 1.1, that is to say transversely to the direction of elevation, in the weft direction in front of the shield pin 1.1 and below the pivotable part 1 of the weapon, one end of which 4.0 is non-rotatably in one via a serration 4.6 with the tower 2 connected bearing block 2.2 is fixed, while the free end 4.1 of the torsion bar 4 is also non-rotatably connected via a serration 4.6 with a protective tube 4.3, which surrounds the torsion bar 4 concentrically for about half its length and that via ball and roller bearings 4.4 is rotatably mounted in the side walls 2.3 of the weapon shaft.
a mist 4.2 is fastened, which is connected in an articulated manner to one end of a spring strut 5, the other end of which is articulated on the pivotable part 1 of the weapon.
the strut 5 contains a compression spring 5.1, the pretension of which can be changed by a screwable stop 5.2. Furthermore, a fixed stop 5.3 limits the deflection of the compression spring 5.1.
the torque of the torsion bar 4 is first transmitted to the protective tube 4.3, which also acts as a torsion bar due to its elastic properties, from which it is finally transmitted to the pivotable part 1 of the weapon via the lever 4.2 and the spring strut 5.
a suitable selection of the point of articulation of the spring strut 5 on the pivotable part 1 of the weapon predefines a crank radius 1.2, while the crank radius of the lever 4.2 is denoted by 4.5.
the preload, the suitable angle of rotation and the torque of the torsion bar spring 4 to be transmitted can be varied by appropriately different selection of these two crank radii 1.2 and 4.5.
the spring strut 5 serving as a further energy store is designed according to the formulas given above.
Fig. 2 two different positions of the weapon system 1 are drawn with solid or dash-dotted lines and the corresponding position of the lever mechanism.
the strut 5 In the position shown with solid lines, which corresponds to a position of the weapon 1 with a high elevation, the strut 5 obviously has a somewhat longer length than in the position indicated by dash-dotted lines, which corresponds to a position of the weapon 1 with a small elevation. This change in length adjusts the gear ratio in the desired manner.
Fig. 3 describes with curves I, II and III the advantageous effects of the additional pressure spring introduced as a further energy storage using the example of a four-bar transmission.
Curve I shows the weapon imbalance torque to be compensated as a function of the weapon elevation ⁇ 2 as a cosine function.
Curve III represents the compensation torque that can only be achieved by the torsion bar spring, whereby only - as the comparison with curve I shows - partial unbalance compensation is achieved.
Curve II provides the compensation torque resulting from the torsion bar and compression spring, the compression spring being designed as a further energy store according to the equations above.
the compression spring In order to be able to store and release the energy necessary for almost complete unbalance compensation, adapted to the cosine curve of the weapon imbalance, the compression spring cannot be biased or biased by the variable stop 5.2. Furthermore, the deflection of the compression spring can also be limited by the stop 5.3.
