摘要:
A quick stop for a drive using a control body (1) mounted rotationally symmetrically on a weapon housing is disclosed for a linear introduction of a breechblock of an automatic cannon, comprising a lower position (9) connected to the control body (1), which once the shot has been fired, is released for moment and when there has been no shot remains blocked. A force transmitter (8) also connected to the control body (1) converts the remaining rotational energy into an axial movement and hence brakes the mass-induced residual movement of the control body (1). The force transmitters (8) in the simplest form thereof are springs.
摘要:
The invention relates to a drive having a quick stop mechanism for a breech (3) or breech carrier which can be axially adjusted relative to a weapon barrel (1), said drive comprising at least one motor (2) or the like, a chain (5) on which at least two engaging cams (7) are mounted, the chain (6) being preferably arranged below the breech (3) and being guided around at least two sprocket wheels (5). A slide (8) is mounted in a guide at the bottom of the breech (3)/breech carrier so as to be displaceable at a right angle to the direction of fire, a groove (9) extending over the entire width thereof. The respective engaging cam (7) entrains the breech (3) in a forward motion in relation to the direction of fire or in a reverse motion once the shot is fired. The engaging cam (7) transporting the breech (3) forwards is displaced out from the groove (9) and is moved backwards without the breech (3) on the other weapon side, thereby allowing rest periods of the breech (3) in the forward end position. Once the shot is fired, the slide (8) is displaced to the other weapon side whereas it remains in the position in which it was put down by the engaging cam (7) when no shot is fired so that no further engaging cam (7) can entrain the breech (3) backwards.

The invention relates to a drive having a quick stop mechanism for a breech (3) or breech carrier which can be axially adjusted relative to a weapon barrel (1), said drive comprising at least one motor or the like, two counter-rotating chains (6) and sprocket wheels (5) around which the chains (6) are guided. Engaging cams (7) and control cams (8) are integrated into the chains (6). A slide (11) is mounted on two guide bolts at the bottom of the breech (3) so as to be displaceable at a right angle to the direction of fire and has a groove (12) into which the engaging cams (7) of the respective chains (6) engage to entrain the breech (3) in a forward or reverse motion in relation to the direction of fire. The engaging cam (7) transporting the breech (3) forwards is displaced out from the groove (12) while the control cam (8) of said chain (6) displaces the slide (11) simultaneously to is center position via its ascent ramp (13), thereby allowing the rest periods of the breech (3) in the forward end position. Once the shot is fired, the slide (11) is displaced from the center position to the other weapon side whereas it remains in the center position when no shot is fired so that none of the engaging cams (7) can entrain the breech (3) backwards.
