Definitions

  • the invention relates to a speed simulator according to the preamble of patent claim 1.
  • the speed simulator of claim 1 improved to the extent that the control movements of the pipe return and pipe flow can be varied in speed and an arbitrary and safe interruption of the control movements is possible, especially during the maximum flow speed.
  • the speed simulator should be portable and can be installed in narrow tube return spaces, preferably in the tower of a self-propelled howitzer.
  • the invention is characterized advantageously in that the hydraulically operable control and piston unit, which is connected to one another in a block construction, creates a manually portable compact unit that can be installed both in narrow pipe return spaces and that can be used by mobile maintenance groups in the field and can be operated safely, which is simple by means of quick-release couplings can be connected to a pressure supply, preferably to a hydraulic pressure supply permanently installed in the turret of a self-propelled howitzer.
  • the return and forward speed of the weapon barrel can be set particularly advantageously variably by means of two throttle valves integrated in the control and piston unit.
  • the retractable weapon barrel can be held in any position during forward or return, which further advantageously makes it possible to check and adjust movement processes on the barrel weapon and on a weapon-side loading device.
  • the one-sided arrangement of the piston rod also allows the control and piston-cylinder unit to be constructed with a short overall length less than twice the piston stroke, so that installation in narrow tube return spaces with a minimum length corresponding to the overall length is possible, for example between a base piece of a returned gun barrel and a turret.
  • Fig. 1 illustrates the arrangement of a speed simulator 1 within a turret 48 rotatable in the azimuth plane of a large-caliber tank howitzer between a part 8 returning and advancing with the weapon barrel 11, preferably the base piece 13 and a weapon-fixed bearing 5, preferably arranged on the turret rim 6
  • Speed simulator 1 consists of a control unit 2 and cylinder unit 3, which are connected to one another in a block construction, with a piston rod 7 protruding from the cylinder 4 on one side at the end 22 (FIG. 2) the bottom piece 13 arranged bearing 50 connected, while the piston rod 7 opposite end 21 of the cylinder 4 (FIG. 2) is also releasably connected to the bearing 5 of the tower ring 6 via a bolt 49.
  • the control unit 2 and the cylinder unit 3 are installed in a simple manner directly to the not shown within the tower 48 via two quick-action couplings 30 Supply connections of a hydraulic pressure supply can be connected. It is constructed in such a way that, against the force acting in the direction 12 (FIG. 2) of a tube catcher arranged in the cradle tube 51, but not shown, a weapon tube 11 pivoted into an index position 53 about the shield pin axis 52 in accordance with the schematic shown in FIGS shift positions for function control of the back and leading parts 8 and a charging device, not shown, with different return speed istsowiedieBewegungsabinsta in any position be safely interrupted or retractable and variable slowly occurring in weft dispensing maximum flow rate vorlaufbar within the gun barrel return length 1.
  • the speed simulator 1 When the piston rod 7 is retracted by the stroke h, the speed simulator 1 has such a short installation length 1 3 that it is in narrow tube return spaces 41 with a gun tube 11 which runs back by the tube return length 1 1 between the base piece 13 and the turret ring 6 Remaining remaining distance 1 2 less than 2 tube return lengths 1 1 or 2 piston stroke lengths h can be installed in index position 53 on the weapon barrel axis 55, which is extended beyond the base piece 13.
  • the arrangement of the speed simulator 1 on the extended weapon barrel axis 55 does not impede the functional sequence of the weapon, in particular the breech, not shown, and the loading device, also not shown, so that a loading process can be carried out from the barrel.
  • the structure and the mode of operation of the projectile simulator 1 are described in more detail with reference to FIGS. 2 to 5.
  • the piston-cylinder unit 3 consists of egg Nem dan sicn known cylinder 4 with a constant inner diameter d 3 having a smooth bore 47.
  • the end 21 of the cylinder 4 contains a provided with a hole 56 56 for fastening a bearing 5 arranged on the tower ring 6 (FIG. 1)
  • the other end 22 of the cylinder 4 contains a sealing element 57 and a guide bushing 58 for guiding and sealing the piston rod 7.
  • the end of the piston rod 7 located within the cylinder 4 is designed as a differential piston 14 equipped and slidable on the wall of the bore 47 with low-friction sealing and guide elements 60.
  • the differential piston 14 contains a hydraulically unlockable 2/2-way valve 17 with two connections and two specific switching positions.
  • the directional control valve 17 is shown in the closed position, so that the cylinder chamber 15 surrounding the piston rod 7 is not directly connected via the inlet 18 and outlet opening 19 of the differential piston 14 to the cylinder chamber 16 delimited on one side by the differential piston 14.
  • the cylinder chamber 15 has a connection 23 at the end 22 and the cylinder chamber 16 has a connection 24 to the control unit 2 at the end 21.
  • these connections 23, 24 can be connected indirectly via hydraulic lines 34, 35, 36 and via a between the lines 35 , 36 located adjustable throttle valve 20 are connected to each other.
  • the throttle valve 20 is also closed, so that in the arrangement according to FIG. 2 there is also no external connection of the cylinder spaces 15, 16.
  • the switch 61 can be operated manually outside the control unit 2.
  • the control unit 2 contains a further 2/4-way valve 27, which can only assume a second switching position 29 automatically depending on the pressure in the switching position “fast forward” (FIG. 4) of the switching valve 26 via a connecting line 45 compared to a first basic switching position 28.
  • Both valves 26, 27 are each connected to a pressure line 31 and a drain line 37, which can be connected outside the control unit 2 via the quick-action couplings 30 to the respective supply network of the barrel weapon.
  • the switching valve 26 is connected to the cylinder chamber 16 via the lines 62 and 36.
  • an unlockable check valve 40 connected to the switching valve 26 with a pilot control line 42.
  • the directional control valve 27 in the basic position 28 connects to the lines 34 and 35 via a line 33 and a check valve 38 which is open in the inflow direction 64 (FIG. 3). Between the directional valve 27 and the check valve 38, the control line 32 of the unlockable directional valve 17 is connected to the line 33, which is connected to the front end of the piston rod 7 and continues within the piston rod to the directional valve 17.
  • Another controllable throttle valve 46 is located in the connecting line 65 between the pressure line 31 and the 2/4.
  • Directional control valve 27 is located in the connecting line 65 between the pressure line 31 and the 2/4.
  • the pressure line 31 is connected to the pilot line 42 of the check valve 40 in the switching position 39 "slow return" of the switching valve 26. bound, whereby the check valve 40 is unlocked and the hydraulic medium 25 can be pressed out of the cylinder space 16 in the outflow direction 63 via the line 62 into the drain line 37 when the throttle valve 20 is closed.
  • the pressure line 31 is in the basic switching position 28 of the directional control valve 27 directly connected to the cylinder chamber 15, into which the hydraulic medium 25 can flow in the inflow direction 64, the piston rod 7 against the force of the pipe recoiler pointing in the direction 12 in the direction 9 and by the controllable Throttle valve 46 is retractable with different return speeds.
  • the pressure line 31 is connected to the cylinder chamber 16 via the automatically opened check valve 40 according to FIG. 4.
  • the directional control valve 27 is able to assume the second switching position 29 in a pressure-controlled manner via the line 45.
  • the speed simulator 1 can also be used to set variable slow forward speeds of the piston rod loaded in the direction of force 12 by the tube recoiler and thus of the parts 8 leading in the direction 10 (FIG. 1).
  • the hydraulic medium 25 from the cylinder space 15 and that via the lines 31, 33, 35 and 36 in the direction can be opened with the throttle valve 20 open differently 64 flowing hydraulic medium 25 flow differently throttled into the cylinder space 16 in accordance with the desired forward speed.
  • the speed simulator 1 (FIG. 1) can be used with low energy consumption and with a high hydraulically transferable return force of, for example, 80 kN, primarily due to low, - connecting lines and valves with a nominal diameter of 6 mm can still be carried manually, so that the speed simulator 1 can also be used for the repair work of other large-caliber barrel weapons, not shown, with caliber diameters ⁇ 90 mm and relatively high forward forces, for example in the field.
