Definitions

  • the subject of the present invention is the mechanical servo-control on site of a telescopic sight on the firing axis of a weapon mounted in superstructure on a turret, or a cupola, of an armored vehicle.
  • the weapon is movable in site around a trunnion arranged at the rear of the turret and the shooter has, to aim the objective, a telescopic sight located in the front part of the body of turret. It is therefore necessary to copy the position in elevation of the weapon on the mobile prism of the telescopic sight so that the line of sight and the axis of fire remain parallel.
  • the document FR A 2421 362 also describes a means of servo-control on the site of a telescope by means of rods cooperating with rack and pinion systems.
  • the object of the invention is to provide a device for copying the position in elevation of the weapon on a telescopic sight, such that the telescopic sight can be placed in any place of the turret and in particular without being aligned with the location of the power take-off box on the trunnion.
  • the subject of the invention is therefore a turret or a cupola of an armored vehicle comprising a weapon mounted in superstructure, movable in elevation around a rear journal and comprising a riflescope whose elevation orientation of the optical axis must be copied over that of the weapon.
  • the device for copying the elevation position comprises, according to the invention, a power take-off box disposed near the journal which supports the weapon and transmitting said movement by means of a flexible transmission member to a feedback box ensuring the movement of the optical axis of the telescope.
  • FIG 1 there is shown a turret 1 of armored vehicle (not mentioned), movable in bearing around the vertical axis of the turret.
  • the shooter has a scope 4 arranged in front of his position so that the eyepiece of the scope is placed in front of his face.
  • a device for copying the movement of the weapon 3 has been produced according to the invention.
  • This device comprises a rear case 5 for power take-off connected to the journal support of the weapon as well as a flexible member 6 for transmitting movement from the rear case to the telescope and a feedback box 7 ensuring the elevation movement of the telescope 4 and arranged at the front end of the member 6.
  • Figures 2 to 4 show the detail of the plug housing movement 5.
  • the latter properly speaking, is fixed by screws 8 to the body 9 of the turret 1, near the journal 2 whose axis of rotation is materialized by a point P.
  • the points S, P, Q and R form the vertices of a deformable parallelogram so that a rotation in elevation of angle ⁇ of the straight line PQ materialized on the part 10 integral with the journal results in a rotation of the same value ⁇ of the straight line SR and of the axis 14 as well as of any part, in particular a pulley linked in rotation, to the axis 14.
  • the straight line QR of this parallelogram consists of an adjustment rod 12 comprising at each end a any male swivel 11a and 11b, one being connected to point Q to part 10, secured to the journal, the other being connected to point R to the link (13), itself linked to axis 14.
  • the axis 14 mounted rotating in the body 15 of the housing 5 by means of two opposing bearings 16, supports a pulley 17 having a circular groove 18.
  • the outer part of the pulley has a recess 19 defining a radial range 10 against which abuts a flange 21 for attaching a cable 22, the end of which carries a stop protrusion 22a crimped on the cable 22.
  • the latter constitutes one of the ends of the movable part of the flexible transmission member (6) whose threaded end piece (23) is blocked in a bore (24) of the housing (5) by two nuts, one (25 ) disposed internally and the other (26) externally to the housing.
  • the flexible transmission member (6) consists of a metallic ribbon sliding on balls arranged inside a flexible sheath. At each end of this ribbon is crimped a metal cable (22).
  • the flexible transmission member 6 is arranged either preferably inside the shield of the turret, or outside of it, if circumstances so require (and this may be the case when the device according to the invention is mounted in "retrofit” on a turret already existing).
  • the "front" end of the member 6 enters the feedback unit 7 by a bore 27 on each side of which it is locked in a similar manner by nuts 25 ′ and 26 ′ (see FIGS. 5 to 7).
  • the housing 7 consists of a hollow body 28 whose main wall 29 is pierced with a bore 30. Inside thereof is mounted by means of two opposing bearings 31 tightened by a lock nut 39, a axis 32 supporting a grooved pulley 33. The connection between the axis 32 and the pulley 33 is produced by means of an expandable sleeve 35. This pulley receives the other end of the cable 22, fixed by a cable tie 34 , itself screwed onto a radial surface of the pulley 33 (in an identical manner to that previously described for the pulley of the power take-off unit 5).
  • the hollow part of the housing 7 is closed by a cover 36 through which the axis 32 and the expandable sleeve 35 pass.
  • the right end of the axis 32 (in FIG. 7) external to the cover 36 bears in abutment against the sleeve 35 , and fixed on the last, a motor pinion 37.
  • On the flank of the latter is bonded a flange 38 of diameter greater than that of the pinion 37.
  • the left end of the axis 32 (in FIG. 7) is contained in an annex box 40 fixed by screws to the wall 29. Inside this box is fixed by a pin 41 the outer end of a spiral spring 42 whose inner end is engaged in a radial slot 43 of the axis 32 (figure 8). The purpose of this spring is to keep the unit permanently under tension in order to make up for all the games.
  • the telescopic sight 44 has been partially shown in Figure 6. Its axis of rotation in elevation (straight materialized in YY) has one end 45 supporting a receiving pinion 46 fixed by a clamp 47.
  • the receiving pinion 46 is driven by the driving pinion 37 by means of a belt notched 48 held in tension by a tension roller 49 mounted idly on a support 50 fixed to the housing 28.
  • This kinematics of remote movement transmission makes it possible to respect on the telescope the angles of displacement in elevation of the weapon with a precision of 2.10 ⁇ 3 radians for movements of the weapon in elevation ranging from -8 ° to + 40 ° angle.
  • the power take-off by deformable parallelogram can be omitted and in this case, the housing 5 is simply reduced to the pulley 17 carried by one end of the journal.
  • the pinion transmission 46 belt 48 is no longer useful. In this case, the connection between the two axes is achieved by means of a coupling sleeve or any other connecting member.
  • the device according to the invention applies just as much to the turrets of original armored vehicles as to the already existing turrets on which it is desired, after a few years of use, to carry out the integration of a new telescopic sight.
  • the device can be used on turrets having no weapon in the superstructure, for example in the case of the copying of the line of sight between the riflescope and the rifle scope.
