Definitions

  • the present invention relates to vehicles for securing routes by causing the explosion of anti-tank mines to pressure.
  • anti-tank mines triggered by pressure. They pose a threat to all types of vehicles. Such mines cause significant destruction of the undercarriage and the body of wheeled vehicles or tracked.
  • the mine is triggered when the total force exerted by the pressure of a wheel on a large plateau, whose diameter can go up to that of the mine, that is to say about 400 mm for the largest known mines, exceeds a certain threshold, which often corresponds to a pressure of less than 1 bar.
  • the mine is provided with several protruding pins having a diameter and a height of one to a few cm (often about 3 cm), each of which can be activated by a force exceeding a threshold which is often of the order of 1500 Newton.
  • Pressure mining systems have already been proposed for activating the plate and pawn sensors in order to detonate the mine as it passes through the system, which is designed so that it can be restarted after an explosion. easy.
  • a first system uses rollers, plows or flails pushed by a tank. These means are very heavy and are not suitable for rapid treatment of traffic lanes that it is desired not to systematically degrade by demining. Such a system is known from WO 02/03007.
  • the most widespread decoy system is constituted by a vehicle having a frame carrying weighting pigs and provided with of pneumatic wheels.
  • a vehicle can be moved fairly quickly.
  • the tires make it possible to follow the irregularities of the ground.
  • the vehicle does not systematically degrade the roadway to be secured.
  • the load on the chassis must be sufficient for the vertical force applied to the ground by the tires to exceed the trigger threshold of the pawn sensors.
  • a ground load of about 2000 Newtons is generally adopted.
  • the wheels Because of this diameter and their width, the wheels have a high ground contact area, greater than that of the plateau mines, which requires very heavy load on the chassis to get to trigger the mines certainly. This involves at present, in the case of a 4 meter track, the passage of 10 tires each 40 cm wide.
  • a demining train currently used consists of three trailers weighing a total of 22 tonnes, to secure a 3.10 meter wide track with 11 tires, each 270 mm wide.
  • the present invention aims to provide a demining vehicle by luring antitank mines better than those previously known to the requirements of practice, particularly in that it significantly reduces the mass of the vehicle.
  • the invention proposes in particular a pressure mine decoy vehicle, having a chassis intended to be coupled to a drive vehicle, and carried by at least one set of wheels characterized in that each set of wheels comprises a brace, rotatably mounted relative to the frame about an axis of rotation, and whose arms each carry a bearing wheel rotating about an axis of a hub, two opposite wheels, relative to the axis of rotation of the cross, being aligned in the rolling direction and offset from the other two wheels, in the direction of the axes of rotation of the wheels and the cross, a length substantially equal to the common width of the wheels.
  • the chassis is carried by at least one undercarriage having a cross member provided at each end of a wheel set.
  • This arrangement makes it possible to use wheels that are still wide, but have a reduced diameter, which reduces the length, and therefore the ground support surface, for demining the same width with vehicles having a much smaller mass. .
  • the problem posed by the impossibility of crossing obstacles by a wheel of reduced diameter is eliminated thanks to the use of a spider bearing 4 wheels, with an offset corresponding substantially to the width of a tire between two successive wheels in the circumferential direction.
  • the wheels will generally be free to rotate around their hubs. The assembly is thus simple and the replacement of a damaged wheel due to the explosion of a mine is fast.
  • the wheels are generally pneumatic whose tread diameter is between 600 and 800 mm, in particular about 700 mm at the present time when the mines of which this is suspected are of the usual type, and a width of between 200 and 300 mm, especially about 250 mm or 9.7 inches.
  • each spider is such that the spacing between the axes of rotation of two successive wheels of the same spider, in the circumferential direction about the axis of rotation of the spider is at least substantially equal to the diameter of the wheels.
  • the invention also proposes a demining train comprising a driving vehicle and several driven vehicles, of the type defined above, whose wheel trains of the driven vehicles have different and adjacent tracks.
  • the two braces of the last train, or the first can be placed outside the set of 4 wheels they carry, so that the wheels can be directly adjacent.
  • the arrangement can also be reversed, the nearest wheels being placed at the front; the first or last train may have a single set of wheels.
  • the first vehicle of the train advantageously carries a rake protruding forward, to blow the mines trapped without damage to the vehicle.
  • the training vehicle can push the vehicle (or vehicles) of decoy, in a traditional way.
  • a "stealth" tractor vehicle that is to say, designed not to detonate the anti-tank mines on which it rolls.
  • the vehicle 10 whose general constitution is shown in FIG. 1 comprises a chassis 12 intended to be coupled to a towing vehicle 14 and capable of supporting loads, constituted for example by pigs, of sufficient weight to provide the required ground pressure.
  • the frame 12 is carried, in the illustrated case, by a single undercarriage.
  • This train has a platform 16 on which the chassis is supported, connected by suspension means to a cross member 18.
  • these suspension means are constituted by two leaf springs placed on both sides. other of the platform, the ends of which are connected to the platform and whose middle portion has a shoe 20 resting on the cross-member 18.
  • the cross-member which will generally consist of several assembled parts, presents to its the ends of the bearings 22 on which turn respective braces 24.
  • the braces are mounted so as to rotate freely and independently one the other.
  • Each arm of the spider carries a hub 26 on which can rotate a respective wheel.
  • the wheels are provided with tires designed to be inflated to a pressure sufficient to exert a force of the order of 2000 Newtons on a support surface of 12 cm 2 , in order to drive a projecting pin belonging to a pressure mine. .
  • each spider two of the arms 28 are arranged substantially radially.
  • the other two arms 30, interposed between the first, are bent so that the wheels 32 they carry are offset outwardly relative to the wheels 34 carried by the arms 28.
  • the offset is substantially equal to the width of ground support of tires.
  • the arms have all the same radial length,
  • twin wheels does not bypass the problem posed by the presence of an obstacle on the ground next to the sensor of a pressure mine. If indeed one of the twin wheels passes on a bump, the ground pressure exerted by the other wheel decreases in proportions that can prevent the triggering of a mine by decoy.
  • the arrangement according to the invention makes it possible to overcome obstacles using wheels of much smaller diameter than the wheels commonly used, while equalizing the forces exerted on the ground by the wheels.
  • a vehicle according to the invention can release the same track width as a vehicle of usual constitution, by replacing each single wheel by 500 mm width by four wheels each having a width of 250 mm.
  • the ground contact area is almost divided by 3, which also divides by 3 the mass of the vehicle.
  • the undercarriage has a behavior similar to that of a bogie.
  • the undercarriage can also be mounted on the chassis by means allowing it to orient itself, as would a self steering bogie.
  • Several vehicles of the type described above may be coupled to each other so as to constitute a train having a sufficient number of wheels so that at least one wheel passes on any point of the width of the route to clear .
  • a towing vehicle equipped with a front rake intended to detonate, forward vehicle, anti-tank mines and possibly also anti-personnel mines.
  • This rake can have various constitutions. It can be constituted by a bracket carried by the carrier vehicle projecting forward and supporting a row of cables or chains dragging on the ground. It can be constituted by crowns of rods or spokes which turn on a gantry articulated on the vehicle and rest on the ground.
  • the vehicle may also carry a magnetic field generator to detonate the magnetic sensor mines in front of the vehicle.
