An armored vehicle is a variety of tracked or wheeled military vehicles with armor protection. It is a collective name for armored military or police vehicles. Tanks are also a type of armored vehicle tracked armored vehicles, but they are customarily classified separately for operational purposes, while armored vehicles are more often referred to as vehicles with less protective and firepower than tanks.
In terms of the prospect of wheeled armored vehicles, 8x8 is undoubtedly the trend of the 21st century, but 4x4 and 6x6 still have a wide market. In order to better cope with the current regional disputes and counter-terrorism demands, and deal with emergencies in a quick and inexpensive manner, most countries are relying more on small, low-cost and rapidly dispatchable wheeled armored vehicles. They weigh about 5-6. Ton, four-wheel drive, this type of vehicle is currently represented by the French VBL (consisting of the head of the light-armored vehicle law), the Italian "Puma" (PUMA) and the Dutch multi-purpose armored vehicle (MPC). Recently, the VN34x4 wheeled armored vehicle launched by the Northern Vehicle Research Institute has highlighted this rapid-reacting design concept, and its comprehensive performance is close to that of advanced foreign wheeled armored vehicles.
Compared with foreign countries, before the 1980s, China almost did not equip wheeled armored vehicles. However, due to the advantage of later development, the pace of development is not slow. At present, the 92-series wheeled armored vehicles developed and equipped in China have applied a large number of mature technologies and have developed a variety of variant vehicles, which are a good example of the universal and economical design concepts. The development of the VN3 wheeled armored vehicle began in 2000. In 2003, a prototype prototype was developed, the F1 Jeep model and the P2 wedge model respectively. China North Industries Corporation finally selected the model code F1 for capital injection. Based on this development, the VN3 lightweight 4x4 wheeled armored vehicle was established in early 2006.
Close to the domestic VN3 wheeled armored vehicle
In terms of appearance alone, the VN3 armored vehicle is somewhat similar to the French VBL and VBR 4x4 light wheeled armored vehicles. It is like an enlarged jeep. The hull line of the body is very clear. The body is small, but it looks very powerful. According to the designers, the vehicle has a total weight of 6 tons, a length of 4.45 meters, a width of 2.2 meters and a height of 2.2 meters. It can ride 4 people.
Standing directly in front of the VN3 armored car, the first thing that catches the eye is the headlights on both sides of the car. These two well-designed combination lamps incorporate advanced civilian technology. The headlights are xenon lamps. The outline lamps and turn signals are all in the form of LEDs. The most notable feature is their long life and high photoelectric conversion efficiency. Then there are two left and right rearview mirrors.
The cover of the power cabin is opened, and the engine , transmission , transfer case, and transmission shafts that are divided into the front axle and the rear axle through the transfer case are arranged in the power cabin from front to rear. The designer built the silencer inside the power cabin and insulated the inner wall of the power cabin with heat-insulating fiber materials to prevent the heating effect of the strong heat source inside the power cabin on the body and reduce the infrared characteristics of the vehicle. Blending engine exhaust with the exhaust of the cooling fan not only helps reduce thermal signatures, but also helps reduce noise. According to radar stealth technology requirements, VN3 also uses infrared stealth paint to achieve shape stealth.
The right side of the engine is equipped with exhaust fans. The fan drive adopts a hydraulic coupling + temperature-controlled axial fan to set high gears, low gears, and neutral gears. Two manual and automatic control methods are provided to enable the engine to operate at different ambient temperatures. Can work in good conditions. The left side of the engine is an air filter. The engine is integrated with the clutch, transmission, transmission, and splitter rigidly in series. Unlike ordinary vehicles, which are scattered and arranged, but formed a module that can achieve the overall lifting. In addition, automatic fire extinguishing devices are also used in the power cabin.
Two pairs of front and rear tires of the VN3 are wide and thick. This type of tire is a low-pressure tire, and one of its outstanding features is its bullet-proof ability. After being hit by a bullet, it can travel 100 kilometers at a faster speed. Another feature is that the tire is equipped with an automatic central charging and deflation system, which can automatically fill and deflate the tire according to the attachment of the tire on the ground and increase the adhesion of the tire on the ground, thereby enhancing the vehicle's soft passing ability and off-road mobility. ability. In addition, in order to improve the vehicle's off-road capability, the car is also equipped with four-wheel independent suspension. It is the off-road maneuverability of these measures for wheeled armored vehicles that makes it difficult to match with tracked armored vehicles.
The inner side of the tire is a disc brake mounted on the bridge. The car is equipped with a full-disc disc brake and has good braking performance. At the same time, like the civilian vehicle, the brake anti-lock system (ABS) device is installed, and the unobstructed movement on snow and ice can further improve the braking performance and braking safety. The axles of general wheeled armored vehicles are housed inside a closed vehicle body. The VN3 is mounted on the outside of the vehicle body. It is said that this will greatly contribute to reducing the interior noise. After testing, the car's noise is within 90 decibels, which is very close to the noise level of civilian vehicles.
The middle of the side of the body is the two side doors provided for the driver and co-pilot to get on and off. Open the door, a front light suddenly, the seat in the cab is leather, in order to adapt to different heights of the driver, but also back and forth, up and down adjustment. In order to make it easier for the driver to get on and off the driver behind, the driver's seat can also be folded forward. It is somewhat similar to the seat design of a civilian coupé.
The layout of the domestic VN3 wheeled instrument panel is also similar to that of a civilian car. Directly in front of the driver is a modular instrument panel , equipped with a virtual instrument and analog instrumentation. The analog meter displays the driver's commonly used signal, the virtual meter displays the less frequently used information, and a large number of background information can be selected by selecting a desired information through a manipulation knob. This design method solves the problem of the diversity of information display for combat vehicles and the complex interface and space occupied by traditional integrated display and control terminals for combat vehicles. At the same time, the manufacturing cost of vehicles is greatly reduced, and the interior decoration of the cockpit is beautified.
About domestic VN3 wheeled armored vehicles
The VN3 wheeled armored vehicle is an all-wheel-drive, lightly armored combat vehicle with high maneuverability and assault capability, small size, light weight, strong strike ability, suitable for aerial delivery, and good ground maneuverability. Equipped with rapid reaction forces and operations, and can be deformed according to user needs. The development of VN3 in China began in 2000. At present, the comprehensive performance is close to that of advanced foreign wheeled vehicles.
