Definitions
- the invention relates to a Richtmomentstabilisator for providing a elevationsunabhangigen directional moment of a elevationsabhangiges weight moment having gun barrel with a counter-force generator for generating a counteracting the weight moment counter force, Furthermore, the invention relates to a weapon with a elevationsabhangiges weight moment having gun barrel and such Richtmomentstabilisator. Especially in the field of medium- and large-caliber weapons, such as battle tanks or artillery weapons, the corresponding weapons tubes often have a very significant weight.
- a Richtmomentstabilisator which has a designed as a pneumatic cylinder counter-force generator for generating the opposing force.
- the invention has the object to create a Richtmomentstabilisator » which can also be used in cramped installation situations.
- the task is gel ö stated that the counter-force generator for generating the opposing force has a coil spring.
- the spiral spring Due to its spirally wound structure, the spiral spring has a compact geometry over its entire travel, so that the counter-force generator can also be used in cramped installation situations. Thus, a space-saving design of the directional moment stabilizer can be made possible by the counter-force generator designed as a spiral spring.
- the counter-force generator has several, in particular parallel, spiral springs, so that the spring forces of several spiral springs can add up to form the opposing force.
- the directional moment stabilizer has an opposing force adjuster for adapting the opposing force to the elevation dependence of the weight moment, and the opposing force adjuster can change the opposing force as a function of the angular deflection or the tension of the spiral spring and thus on the elevation-dependent weight moment can be adjusted.
- the counterforce adjuster is designed as a cam.
- About the cam can one of the spring travel of the coil spring dependent, variable lever arm provided and thus the size of the opposing force can be adjusted specifically.
- the counter-force generator and the counterforce adjuster are designed as an assembly unit.
- the Montageeinheft can be used in the manner of a prefabricated module in the weapon and / or removed from it.
- the processes required for replacement and / or retrofitting the Richtmomentstabilisators can be simplified.
- the counterforce adjuster in particular the cam, is arranged on the spiral axis of the spiral spring, which is conducive to an overall compact construction of the directional moment stabilizer.
- the cam is connected via a shaft with the coil spring.
- the shaft may extend along the spiral axis of the coil spring and be connected to the coil spring, for example by positive engagement.
- the object is achieved by virtue of the fact that the counter-force generator has a spiral spring for generating the counterforce. Due to its spirally wound structure, the spiral spring has a compact geometry over its entire length. By trained as a spiral spring counter-force generator thus a space-saving design of the Richtmomentstabilisators can be made possible.
- the coil spring is arranged such that its voltage increases with decreasing elevation of the weapon barrel, so that the counterforce generated by the coil spring increases with decreasing elevation. In this way it is possible that in the maximum of the weight moment, with a substantially horizontal alignment of the gun barrel, a maximum counterforce is provided.
- the directional moment stabilizer has a counterforce adjuster for adjusting the counterforce, which has an effective lever arm dependent on the tension of the spiral spring, the effective lever arm increasing with increasing tension of the spiral spring.
- the course of the voltage-dependent spring torque of the coil spring can be adjusted to the course of the weight moment. Since the course of the weighting moment of the elevatable weapon barrel follows a circular function, a cam disc is preferably used as an opposing force adjuster, by means of which the profile of the counter-torque can be adapted to the course of a curve function.
- the cam is rotatable about an axis of rotation parallel to the elevation directional axis of the weapon barrel. It is not necessary to arrange the cam on the Elevationsrichtachse the weapon, which reduces the Multenrichtbaren mass of the weapon to transmit the counterforce on the Elevationsrichtachse the gun barrel fst advantageously a flexible tension element, such as a chain or a rope, provided on the flexible tension element the opposing force generated by the coil spring can be transmitted to the Elevationsrichtachse.
- the weapon has a bearing ring for connecting the flexible tension element to the elevation aiming axis, whereby it is possible to use the area of the elevation aiming axis for the arrangement of other components and components.
- the flexible tension element acts on the circumference of the bearing ring, so that the counterforce can act on the weapon barrel via the flexible tension element with a constant lever arm.
- FIG. 1 shows a weapon with an Ardiga gun barrel in a perspective view.
- Fig. 2 is a perspective view of some components of a
- FIG. 3 shows the directional moment stabilizer from FIG. 2 in a further perspective view
- FIG. FIG. 4 shows the weapon from FIG. 1 with a minimal elevation of the weapon barrel in a side view
- FIG. 5 shows the weapon from FIG. 4 at maximum elevation of the weapon barrel in a side view
- Fig. 6 is a diagram illustrating different moments depending on the elevation of the gun barrel.
- FIG. 1 shows a directable weapon 1, which can be used for example in infantry fighting vehicles, battle tanks or ArtiUeriewaffen.
- the weapon 1 has a weapon barrel 2 of medium or large caliber, which is mounted elevatable about an elevation axis E in a Lagerrlng 4 a weapons platform 3.
- the weapon platform 3 may be a part of an azimuth-directed turret of a tank, a howitzer or the like. act.
- a directional drive is provided on the weapon 1, via which a directional moment MR is provided, which must overcome the etevation-dependent weight moment MW of the weapon barrel 2.
- a directional moment stabilizer 10 is therefore arranged on the weapon 1, by means of which the directional moment MR is maintained at a substantially constant, elevation-independent value, cf. Fig. 6.
- the directional stabilizer 10 has a counter-force generator 11, by means of which a counterforce FG is generated which counteracts the weight moment MW of the weapon barrel 2.
- the counterforce FG acts on the elevation direction axis E and there provides a counter-torque MG, which is opposite to the weight moment MW of the weapon barrel 2.
- the counter-force generator 11 has a spiral spring 11 for generating the opposing force. , 11.2, 11.3, which have a compact geometry over their entire travel.
- the counter-force generator 11 can therefore be arranged in a housing 14, which has a comparison with directional torque generators with linear counter-force generators, such. B. pneumatic cylinders, requires little space.
- the spiral springs 11.1, 11.2, 11.3 are designed as spiral flat springs.
- the springs 11 .1, 11.2, 1.3 are each fastened with a spring end 15.1 to a shaft 13 mounted in the housing 14.
- the ends 15.1 of the individual spiral springs 11.1, 11.2, 11 .3 engage in a direction in the direction of the longitudinal axis D of the shaft 13 in the shaft 13 extending groove 13.1 a.
- the other ends 15,2 of the springs 11 .1, 11.2, 11 .3 are positively on a yoke 14.1 of the housing 14.
- the yoke is connected to the inside of the housing 14 via a welded connection fixed to an inner wall of the housing 14.
- the coil springs 11.1, 11.2, 11.3 are clamped in the housing 14 such that there is no contact between the individual turns of the coil springs 1.1, 1.2, 11.3 in the working range of the coil springs 11 .1, 11.2, 11.3. In this way, a frictionless operation of the coil springs 11.1, 11.2, 11.3 are made possible.
- the directional moment stabilizer 10 has a counter-force adjuster 12 designed as a cam, by means of which the counterforce FG is adapted to the elevation-dependent weight moment MW.
- the cam disc 12 is - as well as the coil springs 1.1, 11 .2, 11.3 - arranged on the shaft 13, so that a compact arrangement of coil springs 11.1, 11.2, 11 .3 and cam 12 results around the spiral axis D.
- the axis D is arranged parallel to the elevation direction axis E of the weapon barrel 2.
- FIG. 1 also shows that the directional moment stabilizer 10 is connected to the bearing ring 4 of the weapon barrel 2 via a flexible tension element designed as a chain 6.
- a flexible tension element designed as a chain 6.
- One end of the chain 6 engages an adapter ring 5, which is arranged on the circumference of the bearing ring 4.
- the other end of the chain is connected to a chain holder 12.1 of the cam 12 and can invest in rotation of the cam 12 along the curved outer contour of the cam 12 at this.
- a rope or a belt can be used instead of the chain 5, a rope or a belt.
- an effective lever arm H dependent on the angular deflection or, respectively, the tension of the spiral springs 11.1, 11.2, 11.3 can be provided and thus the counterforce FG can be adjusted in an angle-dependent manner, as will be explained below with reference to FIGS.
- FIG. 4 shows the weapon 1 in a position in which the weapon barrel 2 is slightly lowered below an elevation ⁇ of 0 * .
- this Winket Scheme also referred to as depression the weight moment MW of the weapon tube 2 is lower than in the horizontal position, but has a comparison of the strong eiev considering position of the weapon barrel shown in Fig. 5 MW larger weight moment.
- the coil springs 11.1, 11.2, 11 .3 are arranged such that they are highly tensioned in depression of the gun barrel 2 and thus a high counterforce FG can be provided in the chain 6.
- an elevation-dependent effective lever arm H is provided via the cam disc 12.
- the weapon barrel 2 is spent by the directional drive of the weapon 1 in a position of maximum elevation ⁇ . Since the weight moment MW of the weapon barrel 2 is minimal in this position, only a comparatively small counterforce FG is required to compensate for the weight value MW.
- the arrangement of the coil springs 11.1, 11.2, 11 .3 is therefore ensured that they are only slightly stretched at maximum Elavation of the gun barrel 2 and thus only a comparatively small counterforce FG is generated.
- the course of the individual moments as a function of the elevation of the weapon barrel 2 can be taken from the diagram in FIG.
- the elevation ⁇ of the weapon barrel 2 is plotted on the abscissa axis, the weight moment MW, the counter moment MG as well as the directional momentum MR resulting from the difference formation from weight moment MW and counter moment MG are plotted on the ordinate axis.
- the weight momentum MW increases with decreasing elevation according to a curve function
- the weight moment MW has its maximum at an elevation of 0" and decreases in the area of depression, ie at negative elevation.
- Richtmomentstabilisator 10 a counter force FG is generated, which provides a Jacobmoment MG on the elevation direction axis E, which is directed counter to the weight moment MW in terms of amount and has a similar course. Since the voltage of the coil springs 1 1.1, 11 .2, 11.3 of the directional torque generator 10 increases starting from the maximum elevation of the gun barrel 2, a counter-torque MG is generated, which increases with decreasing elevation.
- the course of the counter-torque MG thus essentially follows the course of the weight moment MW, but has a magnitude slightly lower value, so that an elevation-independent residual moment remains on the elevation direction axis E, which corresponds in magnitude to the directional moment MR.
- This essentially constant straightening moment MR must be provided by the straightening drive of the weapon 1 when elevating the weapon barrel 2.
- the residual torque is chosen such that it has a value clearly different from zero, so that a reversal of the directional moment MR when straightening the weapon barrel 2 is not required.
- the weapon 1 described above has a directional torque stabilizer 10 with a counter-force generator 11, which has a plurality of coil springs 11.1, 11.2, 11.2 for generating the counterforce FG, whereby a space-saving design of the Richtmomentstabilisators 10 is possible.
