Definitions

  • the invention relates to a speed simulator according to the preamble of patent claim 1.
  • a speed simulator according to the preamble of claim 1 is known, which has the particular purpose of testing the retracting mechanism of the barrel.
  • This simulator essentially consists of a piston-cylinder unit, the piston of which is connected on one side to a piston rod and can be acted upon by hydraulic medium and on the other side closes off a gas space within which the gas can be compressed by the oil supply.
  • the hydraulic medium can be drained through a valve connected to the hydraulic chamber of the piston-cylinder unit, so that the piston and thus also the piston rod can be suddenly moved back by the expanding gas volume.
  • This movement is used to simulate the gun barrel return movement, which means that it is necessary to attach this simulator to the mouth of the gun barrel and to place a counter bearing stationary outside an armored vehicle to support the considerable pressure loads. Due to this arrangement, which requires a considerable installation length, and the structure and the mode of operation, this simulator cannot be installed manually in a narrow installation space inside a turret behind the weapon barrel, especially not because the weapon barrel at the rear end has to be pulled back and not pushed back and because with the known device no variation of the forward speed, in particular up to the maximum forward speed and any interruption of the rewind and fast forward can be simulated.
  • the speed simulator should be portable and can be installed in narrow tube return spaces, preferably in the turret of a self-propelled howitzer.
  • the invention is advantageously characterized in that a manually portable, hydraulically operated control and piston unit that can be installed both in cramped pipe return spaces and that can be used by mobile repair groups in the field and that can be operated safely, is provided, which is easily connected to a pressure supply, preferably to a, by means of quick-action couplings
  • a permanently installed hydraulic pressure supply can be connected in the tower of a self-propelled howitzer.
  • the return and forward speed of the weapon barrel can be adjusted particularly advantageously 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 movements on the barrel weapon and on a weapon-side loading device.
  • the one-sided arrangement of the piston rod also allows a construction of the control and piston-cylinder unit with a short length less than twice the piston stroke, which means that it can be installed in narrow pipe return spaces with a minimum distance corresponding to the length, for example between one Bottom piece of a returned gun barrel and a turret ring is possible.
  • 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 can be connected in a simple manner via two quick-action couplings 30 directly to supply connections of a hydraulic pressure supply that are not permanently installed within the tower 48. It is constructed in such a way that, against the force acting in the direction 12 (FIG. 2) of a tube retractor arranged in the cradle tube 51 but not shown, a weapon tube 11 pivoted into an index position 51 about the shield pin axis 52 corresponds to the schematic shown in FIGS Switching positions for checking the function of the returning and advancing parts 8 and a loading device, not shown, can be retracted at different return speeds and can be advanced slowly or at the maximum forward speed that occurs when the shot is fired, and the movement sequences can be safely interrupted in any position within the barrel length I 1 .
  • the speed simulator 1 when the piston rod 7 is retracted by the stroke h, has such a short installation length 1 3 that it remains in narrow pipe return spaces 41 with a residual distance 1 remaining between the base piece 13 and the turret ring 6 with a gun barrel 11 which has returned by the pipe return length I 1 2 smaller than two tube return lengths I 1 or two 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 a cylinder 4 known per se with a smooth bore 47 having a constant inside diameter d 3.
  • the end 21 of the cylinder 4 contains a tab 54 provided with a bore 56 for fastening a to the tower ring 6 (FIG 1) arranged bearing 5.
  • 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 Wegevehtil 17 is shown in the closed position, so that the cylinder chamber 15 surrounding the piston rod 7 is not connected via the inlet 18 and outlet opening 19 of the differential piston 14 directly 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.
  • a known 4/3-way valve arranged as a switching valve 26 the switch 61 outside of the control unit 2 can be operated manually.
  • the control unit 2 contains a further 4/2-way valve 27, which can only assume a second switching position 29 automatically as a function of pressure compared to a first basic switching position 28 in the fast forward switching position (FIG. 4) via a connecting line 45.
  • 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 4/2-way valve 27.
  • the pressure line 31 is connected to the pilot line 42 of the check valve 40, whereby the check valve 40 is unlocked and the hydraulic medium 25 with the throttle valve 20 closed from the cylinder space 16 in the outflow direction 63 via the Line 62 can be pushed out into the drain line 37.
  • 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 space 16 via the automatically opened check valve 40.
  • the directional control valve 27 is able to assume the second switching position 29 in a pressure-controlled manner via the line 45.
  • the connection of the pressure line 31 to the line 33 is interrupted and the line 33 is connected to the drain line 37, so that the control line 32 is relieved of pressure and the directional control valve 17 when the check valve 38 and the throttle valve 20 are closed, which is under the force of Pipe recuperator in the cylinder space 15 building pressure is open and the hydraulic medium 25 in the case of the differential piston 14 which can be moved forward in the direction 10 directly, quickly and without any appreciable hydraulic resistance through the openings 18, 19 and through the relatively large nominal size of the directional control valve 17 from the cylinder space 15 in can flow the cylinder chamber 16.
  • 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 recuperator and thus of the parts 8 leading in the direction 10 (FIG. 1).
  • the hydraulic medium 25 can flow out of the cylinder space 15 with the throttle valve 20 open differently and via lines 31, 33, 35 and 36 in the direction 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) is particularly low in energy consumption and with a high hydraulically transferable return force of, for example, 80 kN, due to its small, preferably nominal size 6 mm dimensioned connecting lines and valves 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 s: 90 mm and relatively high recoil forces, for example in the field.
