Definitions

  • the present invention relates to the field of armoured land vehicles, in particular of armoured vehicles for both military and civil uses.
  • Armoured vehicles are often used for the transport, including the transport of personnel, such as military personnel, in hostile places or for the transport of people whose fame and prestige exposes them to possible personal attacks by delinquent. Armoured vehicles are equipped with armour to protect vehicle occupants from threats such as gunfire and explosions. Protection from land mines and so-called improvised explosive devices (IEDs) is typically provided by a bottom plate (belly armour), designed to have substantial resistance against explosions.
  • the bottom plate is typically a heavy metal plate, sometimes a multilayer plate, sometimes incorporating additional layers of metal, ceramic, composite and/or plastic material.
  • the detonation of an IED under an armoured land vehicle can cause the acceleration of the vehicle's bottom plate or floor.
  • the bottom plate can achieve accelerations higher than 50,000 G and speeds of hundreds of m/s and globally, when the local impulse is transferred to the rest of the structure such as vehicle walls and ceiling, these parts of the structure can reach speeds of the order of 10 m/s, if they undergo accelerations higher than 100 G, for example, of the order of 300-400 G.
  • the detonation of a mine or an IED can also produce a substantial acceleration of the structure or a portion of the vehicle structure, such as the structure wherein the bottom plate is attached, including, for example, the vehicle' s walls and ceiling and/or a vehicle interior floor.
  • the total movement of the vehicle for example, in the vertical direction, is not very high, for example, due to the weight of the vehicle, the acceleration can be very high. This means that personnel inside the vehicle can subjected to forces corresponding to accelerations in the order of many G, such as 100-500 G, for short periods of time such as 10 ms.
  • the classic embodiment of armoured land vehicles provides a frame on which the chassis is mounted. This solution, the most used until now, allows an exceptional ease of configuration of the vehicle, since a specific frame is associated, different "bodies of the car” or rather different chassis based on the intended use and customization required.
  • the present embodiment does not provide sufficient protection to the vehicle occupants since the armoured vehicle has limited ballistic resistance features. Furthermore, this is particularly evident in the case of detonation of a mine or an IED or even in the case wherein the vehicle is hit from the side by large-calibre bullets, bombs, avaoka rockets, etc.
  • the land armoured vehicles known today as they are structurally constituted, they offer a limited resistance to this type of explosions, that is, a limited ballistic resistance, both they occur below and to the side of the armoured land vehicle.
  • armoured vehicles are essentially composed of steel, a heavier but above all more rigid structure is generally obtained; therefore, it often happens that armoured vehicles suffer from a lower torsional and flexural resistance compared to a classic vehicle, made of aluminum, which however has a very limited ballistic resistance, that is, to the explosion. Therefore, it often happens that vehicles using ballistic steel suffer from fractures after even short periods of use.
  • the present invention relates to an armoured land vehicle (1) whose structure allows to solve the aforementioned problems highlighted in the state of the art allowing to have a vehicle that combines both high flexural and torsional resistance and ballistic resistance so as to provide advantages both in terms of mobility and, contextually, of protection and contextually solving the disadvantages mentioned above with reference to the state of the art.
  • the problem addressed by the present invention is therefore that of providing an armoured land vehicle (1) with improved resistance to torsional and bending stresses, up to over 65% and, at the same time, an improved ballistic resistance (to bullets and explosions in general) up to over than 35%, compared to the armoured land vehicles known today.
  • An object of the present invention is therefore an armoured land vehicle (1) comprising:
  • the term "and / or" when used in a listing of two or more items, means that any of the items listed can be used alone, or in any combination of two or more of the items listed.
  • the combination can only contain A; only B; only C; A and B in combination; A and C in combination; B and C in combination; or A, B and C in combination.
  • An object of the present invention is an armoured land vehicle (1) comprising:
  • said armoured land vehicle (1) not only allows to increase the torsional and flexural resistance of the structure, up to over 65%, but also, contextually, to allocate the shock waves due to impact or explosion on the entire surface provide important improvement in ballistic resistance (bullets and explosions) up to over 35%, compared to the armoured land vehicles known today.
  • the roll-bar (3) combined with the monocoque structure (2) allows a sort of "strain distribution system” that helps the calibrated diffusion of the strains and the ability to accumulate and absorb impact energy. Actually, reacting as an energy distribution grid over the entire surface of the monocoque (See FIG. 1 )
  • the roll-bar (3) is made of high-resistance steel integrated into the structure itself.
  • An integral shell is created with both torsional and flexural resistance of 65% higher than the best of classic solutions.
  • the vehicle's chassis becomes a highly resistant "single cell".
  • the structure of the body of the car provides for the design of all the parts considered a single set of surfaces without solution of continuity. This conceptualization ensures that every single square centimetre of the body of the car takes part in the robustness and, especially, in the absorption of energy in the event of impact from both a bullet and an accident.
  • armoured land vehicle (1) comprises troop transport vehicles, generally referred to as APC (Armoured Personnel Carrier) or Armoured Logistic Utility Vehicle (logistic support vehicle) or Armoured Ambulance (armoured ambulance), armoured patrol vehicles and in any case armoured vehicles for specific military or police use (riot control, SWAT ).
  • APC Armoured Personnel Carrier
  • Logistic Utility Vehicle logistic support vehicle
  • Armoured Ambulance armoured ambulance
  • armoured patrol vehicles and in any case armoured vehicles for specific military or police use (riot control, SWAT ”).
  • frame means the load-bearing structure of the various parts that make up the vehicle, typically consisting of a set of metal axles suitable for creating a more or less flat structure on which the chassis or monocoque is positioned and on which all the other characteristic components are mounted, such as, for example, the wheels.
  • a monocoque (2) means load-bearing structure of a vehicle made up of a monolithic element.
  • roll-bar (3) means torsional bar.
  • Plurality of bars (6) arranged vertically with respect to the vehicle means at least 2 bars (6), preferably from 2 to 20 vertical bars (6).
  • the term vertical means that the bars (6) are arranged in the direction from the lower to the upper part of the vehicle (1).
  • Plurality of bars arranged longitudinally on the sides (4) with respect to the vehicle means at least 2 bars (4) arranged on each side of the vehicle.
  • the longitudinal term indicates that the bars (4) are arranged along the length of the vehicle and in parallel to the ground.
  • the term side of the vehicle means, with reference to Fig. 1 , the right or left side of the vehicle with respect to the vehicle's vertical symmetry axis.
  • Plurality of bars arranged longitudinally on the lower part (5) with respect to the vehicle means at least 2 bars (5) arranged on the lower part with respect to the vehicle on each side.
  • the same definitions given above apply to the terms longitudinal and side.
  • the terminology “on the lower part with respect to the vehicle” is intended to refer to the underside of the lower part of the monocoque (2); with reference to Fig. 1 concerning orientations.
  • the bars (4) arranged longitudinally on the sides with respect to the vehicle and/or the bars arranged longitudinally on the lower part (5) with respect to the vehicle are an integral part of the monocoque (2).
  • the bars (4) arranged longitudinally on the sides with respect to the vehicle are placed on the internal side to the vehicle of the monocoque (2).
  • the internal side means the side of the passenger compartment of the vehicle.
  • the bars (4) arranged longitudinally on the sides with respect to the vehicle are at least 2 for each side of the vehicle.
  • the bars (5) arranged longitudinally on the lower part with respect to the vehicle are placed on the external side to the vehicle of the monocoque (2).
  • the external side to the vehicle of the monocoque means the side of the monocoque that appears the outside of the vehicle.
  • the bars (5) arranged longitudinally on the lower part with respect to the vehicle are at least 2 for each side of the vehicle.
  • the bars (4) arranged longitudinally on the sides with respect to the vehicle and/or the bars (5) arranged longitudinally on the lower part with respect to the vehicle have a diameter comprised between 20% and 90% compared to the diameter of the bar having a greater diameter than the plurality of bars respectively arranged longitudinally on the sides (4) and on the lower part (5) with respect to the vehicle.
  • the bars (4) arranged longitudinally on the sides with respect to the vehicle are in number comprised between 3 and 7 for each side of the vehicle and have a diameter comprised between 20% and 90% compared to the diameter of the bar having a greater diameter than the plurality of bars arranged longitudinally on the sides (4) with respect to the vehicle.
  • the bars (5) arranged longitudinally on the lower part with respect to the vehicle are in number comprised between 5 and 9 for each side of the vehicle and have a diameter comprised between 20% and 90% compared to the diameter of the bar having a greater diameter than the plurality of bars arranged longitudinally on the lower part (5) with respect to the vehicle.
