Abstract:
1. A drive provided with a quick stop device operably connected to a breech, or a breech support, of a weapon, wherein the breech or breech support is moveable between a front limit position and a rear position in an axial direction with respect to a weapon barrel of the weapon, wherein the drive comprises: (a) a motor; (b) a chain that is driven by the motor and to which at least two driver studs are fitted; (c) at least two sprocket wheels arranged underneath the breech, wherein the chain with the at least two driver studs is passed around the at least two sprocket wheels; (d) a slide mounted in a guide disposed at a bottom on the breech, or at a bottom on the breech support, so that the slide is moveable transversely with respect to a firing direction, and a groove extends over the entire width of the slide, wherein a respective one of the at least two driver studs moves the breech via the groove either forward in the firing direction or backward after a shot is fired, wherein during times in which the breech is stationary in the front limit position, the driver stud that transports the breech forward is moved out of the groove and the driver stud is moved backward on a first weapon side and without the breech, and when a shot has been fired, the slide moves to the first weapon side, and when no shot has been fired, the slide remains in a first position in which the slide has been moved away from the driver stud so that neither driver stud is in position to drive the breech to the rear position.
