Definitions

  • the invention relates to an entry / exit hatch on an armored combat vehicle with an armored hatch cover which can be opened about a horizontal pivot axis from a closed position into a maximum opening position and a device for mass balancing on the hatch cover with a torsion bar spring located in the pivot axis, one end of which is fixed to the vehicle while the other end is rotationally coupled to the hatch cover.
  • the invention has for its object to provide an entry / exit hatch with the features specified in such a way that on the one hand the best possible view is given in all directions when observing from the hatch and on the other hand the armored and thus relatively heavy hatch covers can be easily opened and closed by hand even if there are additional armor elements on the hatch cover.
  • the basic idea of the invention is, on the one hand, to arrange the hatch in such a way that the hatch cover takes as little view as possible even in the maximum open position and, on the other hand, to ensure that the device for mass balance is not only in the first phase of the invention by appropriate design of the device for mass balance Opening movement of the hatch cover is effective to facilitate opening, but also in the first phase of the closing movement when the hatch cover is to be pivoted inward from the maximum opening position pivoted far outwards.
  • the characteristic curve of the torsion bar spring and the prestress to be selected in each case can easily be adapted to the respective weight of the hatch cover and the resulting torque in the closing or opening direction.
  • the bias can be generated in a simple manner when the torsion bar spring is inserted in such a way that the torsion bar spring is fixed in a desired middle neutral, approximately half-open position of the hatch cover in the relaxed state, for example by means of a spline, in the bearing arranged on the vehicle.
  • FIGS. 1 and 2 can be on the tower, for example otherwise, not shown howitzer tank howitzer.
  • Fig. 1 shows that the hatch cover 4 is arranged in the transition area between the roof plate 1 and the sloping side wall 2 of the tower and in such a way that its closing plane is sloping outwards at an angle of approximately 20 ° to the horizontal.
  • the hatch cover 4 is connected via a bracket 4.1, a pivot axis 4.2 and a bearing block 4.3 to the upper edge of the side wall 2, so that the pivot axis 4.2 lies on the sloping side of the hatch cover 4 and thus pivots it outward in the direction of arrow O and in this case, before reaching the maximum opening position, which is shown in broken lines in FIG.
  • FIGS. 3 and 4 In the state shown in FIG. 3, an additional passive armor 9 is arranged on the outside of the hatch cover 4. In the state shown in FIG. 4 there is a on the outside of the additional armor 9 further, this time reactive armor 10 arranged.
  • the overall thickness of the hatch cover 4 is considerably increased.
  • the total mass of the hatch cover is considerably increased by these additional armourings, so that considerable weight-related torques have to be overcome when opening and closing, at least in the initial phases of the movement.
  • the hatch is provided with a device for mass balancing on the hatch cover, which is described below with reference to FIG. 2.
  • the mass balance device has a torsion bar spring 5 lying in the pivot axis 4.2, one end 5.1 of which is coupled to the sloping side wall 2 with an adjustable form fit via a variable fixed bearing 7 (see FIG. 2B).
  • the variable fixed bearing 7 is provided with an adjustable form fit, for example with a spline or serration.
  • the other end 5.2 of the torsion bar spring 5, which extends beyond the holder 4.1 and passes through a bearing block 4.3, is guided into a protective tube 6 and fixedly connected to it with respect to rotation (see FIG. 2A).
  • the protective tube 6 is in turn firmly connected to the hatch cover bracket 4.1 with respect to rotation.
  • the torque of the torsion bar 5 is first transmitted to the protective tube 6, which also acts as a torsion bar due to its elastic properties, from where it is then only transmitted to the holder 4.1 of the hatch cover becomes.
  • a torsion bar spring is known per se and described, for example, in DE-OS 38 29 860.
  • the assembly of the torsion bar spring 5 to generate the desired bias is carried out in the following manner.
  • the hatch cover 4 Before the vehicle-side end 5.1 of the torsion bar spring 5 is fixed, the hatch cover 4 is brought into a desired neutral intermediate position, which can lie, for example, in the plane V, which contains the pivot axis 4.2.
  • the vehicle-side end 5.1 of the torsion bar spring 5 is pushed into the variable fixed bearing 7 and secured against rotation, for example by means of spline 7.1. If now, starting from the neutral position, the hatch cover 4 is closed, a bias is generated in the torsion bar spring against the closing direction as a function of the spring characteristic.
  • the pretension can be adjusted so that the hatch cover 4 can be easily opened and closed by hand.
  • a locking device which holds the hatch cover 4 in the maximum opening position until the lock is arranged by actuating an outside Hand lever 8 is released.
  • the locking device itself is constructed in a manner known per se and is not specifically shown.
