  • the maximum inclination of the active plane 10 of this bearing 13 with respect to the active plane 9 of the bearing 12 corresponds to an angle ⁇ or the angle difference 90 ° minus ⁇ , the angle ⁇ preferably being 50 , at most 10.
  • the weapon platform 7 is designed as an annular hollow disk arranged parallel to the active plane 11, so that the part of the storage chamber 23 located in the second hollow body 6 (Fig. 2) of the storage 14 form horizontable surfaces for receiving the weapon platform 7.
  • the bearing axis of rotation 18 also takes a congruent position with the bearing axis of rotation 16. In this position, the weapon platform 7 and the vehicle pan or the vehicle roof 2 are together in a horizontal position.
  • the weapon platform 7 of a vehicle roof 2 standing and tilted according to FIG. 2 can be tilted after the pivot axis has been leveled 43 swivel them into a horizontal position.
  • the effective plane 11 of the bearing 14 of the weapon platform 7 assumes a horizontal position, the active plane 10 of the bearing 13 inclined at the angle of inclination P to the active planes 9 and 11, the total angle of inclination ⁇ of the opposite the weapon platform 7 inclined vehicle roof 2 halved.
  • the bearing axis of rotation 17 halves the angle ⁇ formed by the bearing axes of rotation 16 and 18.
  • a further bearing 52 for the lateral alignment of a weapon receiving disc 45 is arranged within the weapon platform 7, the central region of which is shaped in such a way that a shield pin axis 49 mounted at the intersection 15 swivels as much as possible range of tube weapon 50 between small tube heights of less than 45 ° and maximum tube heights of up to 85 °.
  • the bearings 12, 13, 14, 52 contain known, preferably three-wire roller bearings, which are fastened in assembled ring-like bearing chambers 21, 22, 23, 53 (Fig. 2).
  • These storage chambers consist of symmetrical to the respective working planes 9, 10, 11 arranged in and rotations, the outside 12 on the hollow body 4 and the inside of the vehicle pan or vehicle roof 2 in the storage 12 in the working plane 9, and the storage 13 in the working plane 10 on the inside on the bore surface 3 of the hollow body 4 and on the outside on the outer surface 5 of the hollow body 6, in the storage 14 in the active plane 11 on the outside on the hollow body 6 and on the inside on the weapon platform 7 and in the storage 52 also in the active plane 11 on the inside Weapon platform 7 and on the outside on the jacket of the weapon receiving plate 45 are arranged.
  • the bearing ring 51 and the hollow bodies 4, 6 which are mounted one inside the other contain and the weapon platform 7 for leveling each have at least one ring gear 28, 31, 33, 42, 48.
  • a leveling gear 20 coupled to a reset gear 19 is positively connected to the ring gears in such a way that the direction of the weapon platform 7 in the circumferential direction remains unchanged during the rotational movements of the hollow bodies 4, 6 required for the leveling process by the reset gear 19.
  • the drive shafts 24 of the leveling mechanism 20 in the hollow body 4 and the shaft 25 of the reset gear 19 are rotatably mounted within the hollow body 6.
  • a gear 26 of the leveling gear is always in engagement with a gear 29 of the reset gear 19 via an idler gear 27 and the rotatably mounted gear ring 28, while a gear wheel 30 fixedly connected to the shaft 25 of the reset gear 19 is constantly connected to the gear ring arranged on the weapon platform 7 31 is in engagement and a further gear 32 located on the drive shaft 24 of the leveling gear 20 is constantly in engagement with the ring gear 33 firmly connected to the vehicle pan or vehicle roof 2.
  • a rotatable coupling 34 is axially displaceably mounted, which contains on both ends 35, 36 form-locking means 37 for alternately coupling to a coupling disc 38 connected to the drive shaft 24 or to a coupling disc 39 connected to the hollow body 4.
  • the clutch 34 contains in its peripheral region a gear 40 which is connected via an intermediate gear 41 to the one on the hollow. body 6 arranged outer ring gear 42 is constantly engaged.
  • the clutch 34 is in a position 44 connected to the clutch disc 39, whereby a common rotational position of the hollow bodies 4, 6 can be achieved.
  • the clutch 34 is in a position connected to the clutch disc 38, so that at a speed-transmission ratio of the hollow body 4 to the hollow body 6 of 1: 2 simultaneous and uniform rotary movements of the hollow bodies 4, 6 in opposite directions of rotation are feasible.
  • the speed-transmission ratio is determined on the one hand by the number of teeth of the ring gear 33 and the gear 32 and on the other hand by the number of teeth of the gear 40 and the outer ring 42.
  • the speed-transmission ratio of the hollow body 4 to the weapon platform 7 is the same, but the direction of rotation is opposite, so that to achieve the unchanged circumferential direction of the weapon platform 7, with a hollow body 4 moving counterclockwise, the reset gear 19 simultaneously the weapon platform 7 relative to the hollow body 4 moved clockwise.
  • the leveling mechanism 20 can be driven manually via a hand lever 54 or automatically via a servomotor 55. In both cases, the following operating procedures are necessary for leveling the weapon platform 7: To produce a starting position, the coupling 34 must be moved down and the drive shaft 24 rotated until the movement is stopped by a stop 56 attached to the hollow body 6. In this position of the hollow bodies 4, 6, the working planes 9, 11 are in one plane. During this movement, the entire leveling device, due to the toothed wheel 32 engaging in the ring gear 33, relative to the vehicle roof 2 ge turns. However, the weapon platform 7 is rotated back simultaneously via the gear 27, the ring gear 28 and the reset gear 19, so that it does not change its circumferential direction.
  • the coupling 34 To determine the pivot axis 43 of the weapon platform 7, the coupling 34 must be moved upwards. The drive shaft 24 is then to be rotated until a gas bubble from a position sensor, not shown, preferably a circular bubble, which can be attached at any point on the weapon platform 7 or on the receiving disc 45, has reached a maximum stop within the marking. During this rotary movement, the hollow bodies 4, 6 rotated together in the same direction, while the weapon platform 7 has retained its previous circumferential direction.
  • a position sensor not shown, preferably a circular bubble
  • the clutch 34 is to be moved down again until it is disengaged from the clutch plate 39 and locked into the clutch plate 38.
  • the hollow bodies 4, 6 are now moved simultaneously and uniformly, but in opposite directions of rotation, until the gas bubble in the circular level has assumed the central position.
  • the weapon platform 7 pointing in the unchanged circumferential direction is pivoted about the already horizontal pivot axis 43 and also leveled.
  • the receiving disc 45 and thus the barrel weapon 50 can now be laterally directed as desired in a horizontal position of the weapon platform 7 by means of a side directional drive 46 which is stationary connected to the receiving disc 45 via a gearwheel 47 and the ring gear 48 connected to the weapon platform 7.
  • the return gear 19 are arranged at right angles to the active plane 11 of the bearing 14 and the leveling gear 20 perpendicular to the active plane 10 of the bearing 13, contain the lower gear 29 of the return gear 19 and the ring gear 28 and the gear 32 of the transmission 20 and the vehicle-fixed ring gear 33 a helical toothing inclined in accordance with the angle ⁇ .
