Abstract

A drive for a weapon having a drive cam and a connecting rod unit guided in the drive cam. The drive cam includes the firing cycle of the weapon. A connecting rod unit has a front pin and a rear pin, a strut pin. With its front pin, the connecting rod unit engages in the drive cam. The front pin is also connected to a crank, which is driven by an external drive. The strut pin is connected to an overall control slider of a breech block of the weapon. An emergency stop device, which when a shot is fired makes a pin extend and ensures that the overall control slider is taken along. If, on the other hand, no shot is fired, the pin is not made to extend and the overall control slider not moved. Parts of the drive may in this case continue to run.

Claims

1. A weapon drive for a weapon comprising:

a drive curve;

a connecting rod guided in the drive curve, the drive curve includes the firing cycle of the weapon, the connecting rod, in addition to a connecting rod shaft, comprises a front pin and a rear pin as driving pin, the connecting rod engages with its front pin in the drive curve and is guided therein, wherein the front pin is connected to a crank which is driven by an external drive, and the driving pin is connected to an overall control slide of a breech of the weapon and is adapted to engage in a groove-like guide incorporated beneath the overall control slide; and

a connecting rod carriage of the connecting rod,

wherein the connecting rod is pivoted about a pivot point within the idle times of the breech, which causes the driving pin that runs in a groove in the connecting rod carriage of the connecting rod to pivot, and

wherein the connecting rod engages with its driving cam in the groove-like guide in the overall control slide in order to transport the breech.

2. The weapon drive as claimed in claim 1, wherein the connecting rod carriage has four sliding rollers incorporated at the corners of the connecting rod carriage.

3. The weapon drive as claimed in claim 1, wherein the drive curve comprises a front region extending transversely to the breech and a region having a radius, said regions defining idle times of the breech.

4. The weapon drive as claimed in claim 3, wherein the radius is as great as a length of the connecting rod guided in the drive curve.

5. The weapon drive as claimed in claim 1, wherein an overall control slide has a fixed lug and a movable cross slide, wherein, via the fixed lug, the breech is moved forward and the movable cross slide serves to transport the breech back.

6. The weapon drive as claimed in claim 5, wherein the movable cross slide has a recess.

7. The weapon drive as claimed in claim 5, wherein the movable cross slide has a laterally incorporated pin.

8. The weapon drive as claimed in claim 1, further comprising an emergency stop device having at least one kinematic system which forces out the pin when a shot is fired.

9. The weapon drive as claimed in claim 8, wherein the kinematic system is formed by at least one guide, at least one connecting rod guided in a control curve of the guide, and at least one lever.

10. The weapon drive as claimed in claim 1, wherein the driving pin of the connecting rod is mounted in the connecting rod in a spring-loaded manner.

11. The weapon drive as claimed in claim 5, wherein the movable cross slide has a slope.

12. A weapon having a weapon drive as claimed in claim 1.

13. The weapon as claimed in claim 12, wherein slopes or ramps are incorporated into the main weapon housing or into a weapon cradle, said slopes or ramps serving to guide the cross slide and the pin back into their original position.
