Definitions

  • the invention relates to a forward and reverse brake for an automatic firearm, with a mount and a gun housing, which is mounted on the mount from an initial position and can be moved back and forth, with at least two ring spring assemblies arranged one behind the other, the return energy being damped by both ring spring assemblies and the forward energy is only damped by a ring spring assembly and the ring spring assemblies have a steeper spring characteristic when compressed than when relaxing.
  • CH-A-497 678 describes a device for damping the forward and return energy on an automatic firearm, which is mounted in a mount that can be moved forwards and backwards from a starting position , with two ring spring assemblies arranged one behind the other, of which the first spring assembly for absorbing the forward energy and the first and second together for absorbing the return energy are arranged in series, these annular spring assemblies having a steeper spring characteristic when compressed than when relaxing.
  • This known device does not guarantee a floating bearing of the weapon, because when ring springs are used exclusively, the spread of the hysteresis is too large when the spring rings are at a small angle, or the hysteresis is too small when the spring rings are at a large angle.
  • a liquid brake For the floating storage of a firearm, it is known to use a liquid brake.
  • CH-A-427 576 an automatic firearm is described, with a breech housing mounted on a carrier that can move backwards and a damping device acting between the housing and the carrier.
  • This damping device is provided with a liquid brake, which is effective against a rest position when the weapon is advanced.
  • the damping device is provided with a buffer element that elastically catches the forward of the weapon. Buffer element and fluid brake are arranged in series. The buffer element dampens the transmission of the impact that occurs when the breech impacts the breech housing and when the weapon advances to the carrier.
  • This known device has the disadvantage of any fluid brake, it depends on the temperature of the fluid, so that reliable operation is not guaranteed at every temperature.
  • the device according to the invention in that, in addition to the two ring spring assemblies arranged one behind the other, there is also a third, pre-tensioned spring which can be compressed when the weapon is advanced and which relaxes when the weapon returns, the pre-tension being dimensioned in this way that spring forces acting in the opposite direction during the entire return of the weapon act on it.
  • the third spring is supported with its front end on a flange of the mount and with its rear end on a shoulder of the weapon housing.
  • the spring characteristic of the two ring spring assemblies arranged one behind the other preferably increases progressively.
  • the device has the advantage of ensuring a good floating bearing of the weapon in the event of series fire and of preventing the weapon from colliding with the mount in the event of malfunctions.
  • the forward and return device of a firearm consists of a movable part and a fixed part.
  • the movable part is attached to the weapon and the fixed part is attached to the carriage. Only a part of the weapon housing 10 is shown and a rod 11 is fastened to the mount (not shown) by means of a bolt 12.
  • a spacer 14 is fastened with the aid of a nut 13.
  • the spacer 14 has two flanges 15 and 16.
  • a sleeve 17 is supported on the upper flange 15 and a displaceable ring 18 is supported on the lower flange 16, both the sleeve 17 and the ring 18 in the direction of arrow A , the firing direction of the weapon, supported on the flanges 15 and 16 of the spacer 14.
  • a second sleeve 19 is supported on the ring 18 in the opposite direction and is fastened to the weapon housing 10 with the aid of a thread 20. This second sleeve 19 is slidably guided in the first sleeve 17. So that the second sleeve 19 cannot rotate in the weapon housing 10, a fuse 21 is provided.
  • This fuse 21 consists of a spring-loaded pin 22 in a bore in the weapon housing 10, which engages in recesses 23 of the second sleeve 19 and secures it against unintentional rotation.
  • a helical spring 24 which is supported with its front end on a flange 26 of the first sleeve 17 and which is supported with its rear end on a shoulder 25 of the second sleeve 19. This helical spring 24 tends to push the weapon back, that is, in the opposite direction to the arrows A.
  • a sleeve 27 is supported on the one hand on a shoulder 28 of the fixed rod 11 and on the other hand on a shoulder 29 of the movable weapon housing 10.
  • On the rod 11 two more sleeves 30 and 31 are slidably arranged.
  • a first ring spring assembly 32 is arranged between the two sleeves 27 and 30.
  • a second ring spring assembly 33 is arranged between the two sleeves 30 and 31, and a third ring spring assembly 34 is arranged between the sleeve 31 and the ring 18.
  • a fourth ring spring assembly 35 is arranged parallel to the second ring spring assembly 33 between the two sleeves 30 and 31.
  • the first ring spring assembly 32 can only be compressed until the upper end of the sleeve 27 abuts the lower end of the sleeve 30.
  • the third ring spring assembly 34 can only be compressed until the sleeve 19 abuts a shoulder 36 of the sleeve 31.
  • the two ring spring assemblies 33 and 35 arranged parallel to one another can be fully compressed until the individual rings of the ring spring assemblies 33, 35 abut one another, if not, a stop (not shown) is provided to prevent this.
  • the sleeve 31 has a flange 37, with which it is supported on a shoulder 38 of the weapon housing 10.
  • the weapon moves back through the recoil.
  • the weapon housing 10 moves from the position shown, opposite to the direction of arrow A.
  • the sleeve 19 attached to the weapon housing 10 moves relative to the rod 11, also opposite to the direction of arrow A.
  • This displacement of the sleeve 19 relative to the rod 11 the ring 18 is also displaced and the ring spring assembly 34 is compressed.
  • the sleeve 19 approaches the shoulder 36 on the sleeve 31.
  • the spring 24 will relax, since the sleeve 17 does not move and therefore the distance between the shoulder 25 of the sleeve 19 and the flange 26 of the sleeve 17 increases.
  • the spring 24 preloaded in the starting position of the weapon will thus relax.
  • the compression of the ring spring assembly 34 also displaces the sleeve 31 and the ring spring assembly 33 and 35 is compressed.
  • the compression of the ring spring assemblies 33, 35 also displaces the sleeve 30 and compresses the ring spring assembly 32. Since the sleeve 27 is supported on the shoulder 28 of the rod 11, it cannot move when the weapon returns. Thus, when the ring spring assembly 34 is compressed, the sleeve 19 will move against the shoulder 36 of the sleeve 31 and finally touch it. As soon as the two sleeves 19 and 31 touch, the ring spring assembly 34 can no longer compress itself more.
  • the force increases from value A to value B when the weapon returns from position A 1 to position B1, i.e. the spring characteristic is still relatively flat. Then only the ring spring assemblies 32, 33 and 35 will compress, so when the weapon returns from position B 1 to position C 1 the force will increase more and reach the value C, i.e. H. the spring characteristic is somewhat steeper. At this point C, the sleeve 30 will touch the sleeve 27 and the ring spring assembly 32 can no longer compress itself more. If the weapon moves further back, e.g.
  • the weapon Since the weapon still has kinetic energy at point A1 when it reaches its starting position, it will advance to point E1.
  • the shoulder 29 of the housing 10 is pushed against the sleeve 27 and the shoulder 38 of the housing 10 is pushed against the sleeve 31.
  • the two sleeves 27 and 31 simultaneously move forward by the same amount and the ring spring assembly 32 is not compressed, but only the ring spring assembly 34 is compressed. Therefore the force increases relatively steeply from the value A to the value E.
  • this force drops without shifting the weapon to the value E2, since energy is lost again due to friction.
  • the weapon arrives at position A1 in its starting position, the energy falling to the value A2.
  • the spring characteristic of the ring spring assembly 32 can be influenced by a spacer 39.
  • the compression stroke a of the first ring spring assembly 34 will be smaller than the compression stroke b - of the second ring spring assembly 32.
  • the spring characteristic F of the third spring 24 is relatively flat.
