Description

PROTECTION DEVICE FOR MILITARY SUPPORT VEHICLE}

The present invention relates to a concept for protecting a medium weight military support vehicle.

Medium weight military support vehicles are vehicles for supporting military wheel vehicles and track vehicles in a weight class of 25t to 45t. These support vehicles fall into four or more categories: rescue work, bridge installation, engineer work and mine clearance.

According to known usage principles, medium-weight support vehicles are used to reinforce peacekeeping measures, among other things, in addition to traditional use scenarios such as attack situations and serious situations, in which case these vehicles are subject to ballistic threats. It is exposed 360 ° and is threatened by antitank defense mines and personal mines and by explosives. This creates the necessity to protect the vehicle against its surroundings. However, there is also a requirement in the background of such vehicles to be able to load air.

An object of the present invention is to propose a protection scheme that can satisfy not only the requirement of protecting the crew but also the possibility of air loading of the vehicle.

This problem is solved by the features of patent claim 1. Preferred embodiments are described in the dependent claims.

The present invention is based on the idea of providing at least an area in the vehicle with a suitable perimeter guard used to accommodate the crew. Other areas have minimal protection designed to defend against threats from the ground.

An important feature of the proposed protection scheme is the separate crew compartment, which disengages the coupling and closes itself. Under the tank bottom of the chassis, the crew area is equipped with a mine protection plate. In addition, the crew compartment is strictly separated from the hydraulic region or the chassis frame region. Such measures minimize the risk of crew due to the possibility of explosion of flammable liquids. Add-on-Armour is installed in the outer area of the crew room. Reactive and / or active protection modules are also provided that defend against horizontally operating antitank defense weapons or guided mines. Inside the cabin, a liner is mounted, which on the one hand reduces ballistic penetrating shiver cones, and on the other hand, the blockage of structure-borne sound and Causes adiabatic action. The crew cabin and / or chassis may also be equipped with reactive anti-tank defense weapons or horizontally acting anti-tank defense weapons or reactive and active protection modules.

The crew hangs up inside the chassis frame through suitable bearings. A similar crew room is already known from DE 196 53 283 C1 and DE 10 2004 026 237 A1 and DE 10 2004 006 819 A1. The bearings, on the one hand, absorb shock loads resulting from the explosion of landmines or explosives, minimizing the vibration loads and the acoustic loads due to the structure.

The crew room also has additional visual windows and angle mirrors of sufficient size for direct external surveillance and electronic surveillance means such as daytime surveillance cameras and nighttime surveillance cameras or daytime surveillance sensors and nighttime surveillance sensors. Doing. Additional cameras and sensors mounted on the vehicle are used to convey sufficient information about the near periphery to the crew (similar to a civil vehicle configuration).

The visible window is designed with Pz-layered glass that protects against corresponding threats and is equipped with a laser protection filter to protect the crew's eyes from unexpected laser beams. A screen can also be provided which can be lowered or opened to the left or right, which can be used for the purpose of defending the debris by forming additional ballistic protection on the one hand, but on the other hand, the crew room must be darkened. Can be used as passive protection. Of course, the screen is also used to prevent the light reflecting action on the window surface.

In addition, a type of intercommunication device may be incorporated into the vehicle to avoid situations in which the crew must open the door or hatch if they wish to contact outsiders.

By incorporating the crew seats into the crew room, the crew room meets the requirement that the load be reduced in case of mine explosions and in the case of vibration isolating. The seat is provided with a restraining system and a corresponding head support. The crew may also use at least one hatch, preferably in the roof area, and preferably a door at the rear of the crew compartment.

The crew cabin also has protective action and air handling facilities to protect against ABC-threats and air conditioning equipment for the crew cabin. Such a configuration can reduce the physiological burden of the crew.

The chassis has a closed hydraulic area in addition to the basic protection for extending the life of the system, in which parts of the fuel installation can be arranged. The hydraulic chamber and the engine chamber each have fire fighting facilities on their side. A fire-wire sensor is integrated in the intake area of the engine cooling system, which switches off the cooling fan in the event of an external fire.

Active protective measures create additional equipment in the vehicle itself. Such additional installations include, for example, a spray launch device and a weapon installation that can be controlled manually or remotely. Jamming transmitters present a challenge to cause explosive release from a distance in front of the vehicle.

Passive protection measures are provided in addition to suitable camouflage nets, camouflage kits that reduce or severely modify optical IR- and radar signatures. In addition, engine exhaust and cooling air are exhausted from the rear of the vehicle in a shielded state. Additional air thinning, rear exhaust and insulation measures are used to shield the hot gas against the vehicle structure. Particles in the exhaust gas of the engine can be minimized by suitable internal motorized measures and / or filters.

The engineer tanker is equipped with an excavator device equipped with a quick change system, and the engineer tanker can replace tools while protecting the tank in any operation. Bulldozer work and minesweeping work likewise takes place only in the protection of tanks. The rescue vehicle is provided with a battlefield rescue device to protect damaged vehicles while protecting the tank. Bridge-mounted tanks were similarly designed to install and lift modular bridge parts. Such vehicle designs may be combined with each other. Thus, the so-called universally-supported vehicle incorporates the main features of the rescue, engineer, and mine clearance variants. Bridge installation variants are formed by deforming the base structure during roof construction and by arranging the crew compartment. The same chassis is used as the base of different vehicle variants. Such a concept is also known from EP 0 974 510 A1.

The invention is described in detail with reference to the accompanying drawings.

1 is a schematic diagram showing a protection device in a vehicle as viewed from the left;

2 is a schematic view showing a protection device in a vehicle viewed from the right side;

3 is an exploded view of a protection device in a vehicle.

1 and 2 show a variant of the universally-supported vehicle 1. In this variant, the support vehicle is designed as a minesweeper vehicle and an excavator vehicle. The vehicle 1 is operated by the crew 2 in the crew room 3. The closed crew compartment 3 is disengaged from the chassis 4 using suitable members.

The crew room 3 has a visible window 31 made of Pz-multilayer glass and an additional armor-plating. The crew compartment 3 also has a roof hatch 33 and / or a rear hatch 34. The crew room 3 includes an air treatment facility 35 to protect against ABC-threats and an air conditioning unit 36 for the crew room as a suitable protective measure. In addition, the crew chamber 3 is surrounded by a hood 5 which houses the side adaptive protection 52 and the roof protection 52 on the one hand. On the hood 5, a commander dome 53 and a weapon installation unit 54 are mounted. In addition, a spraying device 55 may be installed on the hood 5 or on the weapon installation unit 54. Alternatively, it is also possible to install in the vehicle chassis 4. The explosive grenade can also be fired by the spray agent 55.

The visible window 31 can be protected by a flap screen 37. In this case, the crew has sufficient view even by the angle mirror 38.

Under the chassis 4, a mine protection plate 41 is provided in the crew compartment 3 area. The running work area 42 may be covered by an apron 43 for chains in front, in the rear and in the side.
