Description

The invention relates to a device with the features of the preamble of claim 1.

Directional drives for aiming an Iafettierten weapon are normally designed so that of it applied torques the required directional acceleration of the weapon overcoming the can apply existing load torques, such as frictional or unbalance torques. Such directional drives however, they can be used to hold the weapon after a shot or a series of shots has been fired to be weak. In the case of non-self-locking directional drives, the weapon is then as a result of the shot triggered angular momentum pivoted out of the target direction. This can be a disadvantage if the The weapon or weapon system should fire again as soon as possible after a shot has been fired, because the time Too long to re-serve, be it to the previous target direction or to a new target direction is.

A known device of the type mentioned in the preamble of claim 1 has a hydraulic one Directional drive, in which blocking signals and unblocking signals are used as hydraulic valves trained blocking device can be derived from a pivoting movement of the barrel weapon (DE-OS 29 374).

A device of the type mentioned at the outset is also known. (US-PS 23 81162) in which the also hydraulically designed straightening drive can be blocked and unblocked via valves that are actuated by return movements of the gun.
The invention is based on the object of designing a device of the type mentioned at the outset, in which the directional drive itself is too weak to hold the weapon firmly after firing a shot or a series of shots, so that the weapon does not move out of the target direction even when the shot is fired. is swung out.

The features of claim I serve to solve this problem.

The invention is particularly advantageous in a stabilized weapon in which movements of the

If the base, such as a tank, is kept away from the weapon and it remains fixed in space, it can be used because the stabilization can start to work again with a minimal delay after the shot has been fired.
Two advantageous embodiments of the invention are protected in the subclaims.

tet is that the two piston chambers of a hydraulic supporting the weapon against the base Cylinder connects. However, the blocking device can also be of a through the shot receiver controllable brake of conventional design be formed, which is supported on the base.

The invention is explained in more detail below with reference to two exemplary embodiments.
In Fig. 1 is denoted by 1 a barrel weapon which is pivotable in a pivot point S relative to a base 2, z. B. the tower or structure of a tank is supported. When the shot is fired, the recoil force F of the barrel 3 of the weapon exerts a torque Md about the lever arm a between the barrel axis 4 and the pivot point 5. The weapon seeks to pivot this torque out of the set target direction in the exemplary embodiment shown upwards.
In order to counteract this, a blocking device, denoted overall by the reference number 5, is installed between the tube 3 and the base 2. The blocking device comprises a hydraulic cylinder 6 with a piston 7 playing therein, the piston rod 8 of which is articulated on the tube 3, while an extension 9 of the cylinder 6 is articulated on the base 2. The two piston chambers 10, 11 of the cylinder 6 can be connected to one another by a bypass line 12 in which a shut-off valve 13 is switched on. This shut-off valve interrupts in

so closed the bypass line 12, so that the piston 7 is blocked in the cylinder 6 and thus also the Prevents weapon 1 from pivoting about pivot point 5.

The shut-off valve 13 can be actuated by the output signal of a shot receiver 14, which emits an output signal in the direction of the shut-off valve 13 at the time the shot is fired. This signal passes a timing element 15 which allows the actuation signal from the shot receiver to pass at the time fo the shot is fired and which cancels this actuation signal again at a time? I which can be set on the timing element. The shut-off valve 13 is then automatically returned to its open position as a result of the absence of an actuation signal. The duration t \ - to, during

f> 5 which the shut-off valve 13 is blocked becomes like this chosen that the weapon 1 remains blocked as long as the angular momentum is greater as a result of the shot al «; from the directional drive, not shown, of the weapon

applicable torques.

Fi g. 2 shows an alternative for the blocking device 5 according to FIG. 1. The blocking device 5 wH? ' here a housing 20 which is hinged at 22 to the barrel weapon i. A length-adjustable strut can be telescoped out of the housing 20. The strut has a muttei 23 articulated to the base 2 at 2 \ . A spindle 24 is screwed into the nut ZI without self-locking. The spindle 24 carries with it a pinion 25 in a rotationally fixed manner, which meshes with a spur gear 26 of larger diameter. A brake disk 27 of a permanent magnet brake, which has a permanent magnet 28 fixed to the housing, is arranged coaxially and in a rotationally fixed manner with the front end 2 &. Of the

Attraction of the permanent door ^:! .gnetf? n a force of resistance holds the equilibrium, which is avoided by means of a tension over the Schaiiunt; J 'anv .'- t _6l e tension.

When the shot is fired, the shot pick-up 14 sends an actuation signal to the 7eitelied 15. This causes the voltage in the circuit 29 to drop, so that the permanent magnet 28 now attracts the brake disk 27 and blocks the blocking device 5 and thus the barrel weapon at the time the shot is fired. After the line / ·, - Zn has elapsed, the voltage is automatically reapplied and the blocking state is thus canceled again.
