Definitions

  • the invention relates to a device for manually rotating an armored turret, straightening a weapon or the like by means of a hand crank via a gearbox with a drive pinion and driven wheel and a dental arch attached to the armored vehicle, in which the driven wheel engages, in which a locking device is provided.
  • a device of this type is known (technical service regulation (TDv) 1015 / 018-12 "turret and armament battle tank Leopard A4", June 1978), in which the locking device is formed by a pawl which must be operated manually by the gunner , which is cumbersome and time-consuming and also requires attention.
  • the object on which the invention is based is seen in creating a device of the type mentioned, in which the locking device is particularly simple and expedient, and in particular is automatically active, in such a way that it no longer requires actuation by the gunner.
  • the locking device is provided in the crankshaft arranged between the hand crank and the drive pinion and is designed to be self-locking with a clamping body.
  • the crankshaft is divided and the locking device consists of a drive claw arranged on the crank part of the crankshaft and an output claw arranged on the output side part thereof, which are radially opposite one another and between which the clamping body in the form of a locking wedge is loosely inserted.
  • This locking wedge lies when the driven claw moves by a rotation of the armored turret under its action in a locked position, so that the driven claw cannot rotate any further and in particular the driving claw cannot give any torque. If, on the other hand, the drive claw is moved by turning the hand crank, then it moves the locking wedge out of the locking position in such a way that the output claw is carried along via this locking wedge.
  • the locking wedge is preferably a metal plate which has cutting edges on both sides in the longitudinal direction of the crankshaft, the flanks or parallel surfaces of which have lateral distances from both the drive claw and the output claw, a compression spring being inserted between the metal plate and the output claw.
  • This compression spring is expediently a flat form spring that takes up little space. The movement of the output claw thus presses the locking wedge or the metal plate into the locking position via the flat spring, the compression spring ensuring that the metal plate is always preloaded into the locking position.
  • a slip clutch between the output-side part of the crankshaft and the drive pinion ensures that a relative rotation of the drive pinion can also take place in the locked position of the crankshaft, namely when e.g. the gun barrel, which hits an obstacle when the armored vehicle is moving, should exert such a large torque on the drive pinion that the device would break without the slip clutch.
  • Fig. 1 shows the device according to the invention for manually rotating an armored turret 1 by means of a hand crank 2 via a gear 3 with drive pinion 4 and driven wheel 5, as well as with a toothed arch 7 attached to the armored vehicle 6 Armored ceilings shown.
  • the stationary dental arch 7 is formed on its outside in a known manner as a side pivot bearing 8 for the peripheral edge 9 of the armored turret 1.
  • the output gear 5 engages in the toothed arch 7 and meshes with the drive pinion 4 arranged on a crankshaft 10.
  • a self-locking locking device 11 is now provided in the crankshaft 10 arranged between the hand crank 2 and the drive pinion 4.
  • the crankshaft 10 is advantageously divided and the locking device 11 consists of a drive claw 13 arranged on the crank-side part 12 of the crankshaft 10 and an output claw 15 arranged on the output-side part 14 of the same, which are radially opposite one another and between which a locking wedge 16 is loosely inserted .
  • a slip clutch 17 is also arranged on the output-side part 14 of the crankshaft 10.
  • the arrangement is such that the crankshaft part 14 on the output side consists of an inner crank part 14 'with coupling part 17' and an outer, coaxial hollow crank part 14 "with coupling part 17" and the drive pinion 4.
  • the engagement of the slip clutch parts 17 ′ and 17 ′′ with one another results in a frictional connection between the output claw 15 and the drive pinion 4.
  • the locking wedge 16 is a metal plate 21 (FIGS. 2 and 3) having cuts 19 and 20 on both sides in the longitudinal direction 18 of the crankshaft 10, the flanks of which have lateral spacings 22, 23 both from the drive claw 13 and from the output claw 15 have.
  • a compression spring in the form of a flat-shaped spring 24 is inserted between the metal plate 21 and the driven claw 15.
  • the same is in a groove 21 ′ of the metal plate 21 on the one hand and in an opposite groove on the other hand 15 'of the output claw 15 held.
  • the radial width b of the metal plate 21 is slightly smaller than the clear width B of the claws 13 and 15 surrounding the gear housing 25, such that in the rest position the metal plate 21 from the compression spring 24 to the contact of the cutting edges 19 and 20 on the inner circumference 26 of the gear housing 25 can be pressed out of the central position between the two claws 13 and 15.
  • the cutting edges 19 and 20 of the metal plate 21 are offset relative to its longitudinal center plane 27 towards the drive claw 13. It is thereby achieved that the locking wedge or the metal plate 21 in FIG. 3 only has to be pressed slightly to the right onto the drive claw 13 in order to bring its cutting edges 19 and 20 into engagement with the inner circumference 26 of the gear housing 25. As shown in FIG.
  • the transmission and thus the drive claw are blocked as a result of the introduction of a torque by the driven wheel 5 via the drive pinion 4 and the slip clutch 17 onto the driven claw 15 in the direction of arrows C and D in that the driven claw 15 Via the compression spring 24, the locking wedge or the metal plate 21 presses to the right, so that the cutters 19 and 20 come to rest on the inner circumference 26 and, as indicated by the arrow E, the force is introduced into the stationary gear housing 25.
  • the cutting edge 19 (and of course also the cutting edge 20 as a reaction) fix themselves in a self-locking manner on the inner circumference 26, so that the torque cannot be passed on to the drive claw 13 and the hand crank 2 thus remains at rest.
  • a torque exerted by the hand crank 2 according to arrow F can be transmitted very easily via the gearbox to the dental arch 7, since according to FIG. 5 this torque F via the drive claw 13 and that exerted by it Torque G pushes the metal plate 21 out of the blocking position to the left and this can then transmit the torque according to arrow H to the output claw 15, which transmits the same via the slip clutch 17 and the drive pinion 4 according to arrow K via the output gear 5 to the dental arch 7. Since the gear 3 is attached to the turret 1 by means of a holder 28 (FIG. 1), this turret 1 can thus be rotated about its vertical axis of rotation, not shown, perpendicular to the plane of the drawing.
  • the tank tower 1, the indicated armored vehicle 6 and the dental arch 7 have been omitted for the sake of clarity.
  • the driven wheel 5 moves in the manner explained with reference to FIGS. 2 and 3 via the driven claw 15 and the shaped spring 24 the locking wedge or the metal plate 21 in a locking position, which corresponds to that according to FIG. 3, but can of course be completely different in its angular position, depending on the rotational position of the metal plate 21 inside half of the gear housing 25 is just. A forwarding of the torque to the drive claw 13 and thus the hand crank 2 cannot take place.
  • the device according to the invention can be used in the same way for a manually operated drive of the leveling mechanism of a weapon.
  • external forces are conceivable, which may aim to depress or raise the weapon barrel, with a reaction to the crank handle in question and the hand of the respective gunner also to be avoided.
