Our People's Liberation Army always has a strong desire for high technology equipment in the 50's Sino Soviet friendly period, our army all aspects of the introduction of the Soviet equipment, including parts of BTR-152 series 6 wheel drive vehicles. And we had planned to carry out independent research and development of wheeled armored vehicle, but it failed because of lack of experience and supporting industries and backward.
In a complete breakdown of the Sino Soviet relationship after 60 years, our army need a four wheel drive light command vehicle equipped with the PLA. After a series of twists and turns, Beijing automobile factory (BAF) successfully developed BJ212 light command vehicle, and the first time through the identification of armed forces, the prototype vehicle and subsequent modified car production has been extended to 2010. Served in the car for more than 50 years, for our army in various foreign war distinctions won in battle. But this model is too old. Problems of insufficient power, transmission efficiency is low, the noise is too large, and some other small problems. It is too difficult to be effectively improved
In the mid 1990's, BAF began to develop a large 4 wheel drive command car, to replace the BJ212 series. After the Sino US cooperative R & D (BAF and Chrysler set up a joint venture company) and later BAF starting second improvement independently, it formally entered the army in 2008, and BAF developed a mass production by 8000-12000 units a year, and then make its provement in good order.
While working on the R & D warriors, the U.S. military ’s Hummer series 4WD command vehicle came into the sight of military leaders after the baptism of the Gulf War, and its excellent mobility, large body, rich potential for modification is very attractive. In 2002, Dongfeng Automobile (DA) started to reverse the development, they developed the chariot on the basis of the improvement, and it is very suitable for our army and suitable for new era ideological battle. Accompanied by a variety of U.S. troops in Afghanistan and Iraq war on terror is not smooth, the damage that Hummer attacked by a roadside bomb and RPG battle straight up. It is also difficult to effectively protect the crew even in the increased armor. Although our chariot has its armored strengthen version, the open body structure is insufficient to protect from roadside bombs.
After North Vehicle Research Institute (NORTH CAR) officially approved in the year of 2000, they began developing this vehicle. As a type of traction by R & D models, VN3 has been calibrated parameters in all aspects. Using the high performance of the diesel engine, four wheel independent suspension, the whole box structure, complete sighting system, having many potential for modification parameters. With unchanging devotion to the motherland prepare for two possible alternatives, based on independent research and development also draws heavily from the French army equipped with VBL light armored vehicle. And they make a reference for light vehicles in the late Japanese equipment.
This is the VBL light armored base vehicle French army equipment, is equipped to the French army and the foreign legion. This car is involved in almost all the French foreign military action.
This is light armored vehicles, the Japanese army service equipment, and its R & D time with our army almost identical to the VN3. And they have similar operational thinking.
North car’s VN3 4WD armored cars is similar in appearance to the Japanese light armored vehicles and the French VBL. Suspension transmission in VN3 has a blood relationship with 4WD system steam warriors, but the interiors are different. Above is Korean KIA‘s new universal 4WD command vehicle, and the looks are integrated to U.S. Hummer interior style. It is compared with the VN3, so that readers have a clear understanding.
NORTH CAR has faced many problems when R & D at the beginning, including the chassis and suspension style on the configuration. The preselected Chaoqjao dynamical system is subjected to the body size and engine capacity, it is kind of like a small horse pulling a big carriage.
The warrior vehicle still use the bearing body trapezoidal girder structure, this setting of chassis armor protection is very weak. While NORTH Car’s VN3 type was decided to adopt the welding armor enclosed structure at the beginning, Outstanding characteristic is that the girder was instead of body structure of the whole welding using cassette, similar to the small passenger car of the bearing body, but strength and bulletproof is much better.
This is a non bearing body structure of the use of the warriors; transmission and suspension system are arranged on the frame.
Pictured above is the right front suspension and a drive axle brake system features. Based on these spare parts, a comprehensive adjustment of North car is in order to adapt to changes in VN3 power. But the sources of technology still come from supporting system of the warrior. It also can get the maximum effect by using the minimum cost in the shortest time, reduce development risk.
Pictured on the left is the right front suspension and a drive axle brake system features. Based on these spare parts, a comprehensive adjustment of North car is in order to adapt to changes in VN3 power. But the sources of technology still come from supporting system of the warrior. It also can get the maximum effect by using the minimum cost in the shortest time, reduce development risk.
This is VN3's right front suspension features. We can clearly see: lower arm mounted on the sub frame, the upper swing arm and the shock absorber is fixed in the body welding. Then the set of sub frame transmission, suspension system and body is fixed. The wheel hub and the steering knuckle assembly are provided as spare parts. The installation position, the brake disc to the outer pull rod, front stabilizer bar and front stabilizer bar vertical rod are welded on the front part of the body function. This and the vapor warrior suspension are similar but different installation method and position.
Look here, this is highly similar chassis structure of Japanese Light Armored Vehicle Front sub frame, steering feature section, upper and lower arm.
This is a positive feature of suspension VBL light armored car French army equipment. We can see the lower arm, the drive shaft, the upper swing arm and knuckle installation structure and VN3 has a great similarity degree from the picture.
It uses inter axle braking form, can avoid the central air charging and discharging system for wheel interference within.
The transmission shaft drives the propeller is drawn from the rear differential, which make the car have amphibious function.
Combat weight of the power system is nearly 10 tons, and its dead weight is 6 tons. After three rounds of screening, 10 long distance test, to ensure the future combat ability after modified car, it was the final calibration can output 170 horsepower Dongfeng Chaoyang Diesel Power System (early version 140 horsepower Dongfeng Cummins, export-oriented features a 320 horsepower MTU diesel power train). In the medium-term development of the vehicle, the sales of our allies: the need for a light armored vehicle. The car must have certain flexibility in the border conflict in low intensity, occupies a great tactical advantage. The north car group for the development of VN3 to make appropriate modifications, to comply with the allies in the eastern border with India boundary, technical and tactical requirements and plateau in the environment. Therefore in the same chassis are respectively introduced two different styles of version.
This is expected R & D F1 Jeep type; it is very consistent with the actual situation for our army to use regardless of appearance or suspension power matching. The early VN3 models (set position lamp can be distinguished). Vehicle front engine compartment appearance has a certain bomb angle, but the geometry engine is greater than that of the nacelle height, so the engine cover protruding part has become one of the most obvious sign of recognition of the car. But the car in reference to the French VBL some problems, provides a good field of view for the member, body protection grade.
This is the VN3 F2 type wedge type body development to meet requirements of the allies. Eventually it was shelved because it will not be allies’ choice, but the result of R & D and accumulation technology was retained, it provides the technical reference for the modified car future VN1, VN2.
This is the VN3 F1 command vehicle structure diagram (this is early VN3 structure according to the position of the lamp ).Engine front longitudinal arrangement, connected with the gearbox transfer case, because the absolute height from the ground vehicles., a large space, r transmission transfer case is highlighted in the cockpit. This layout setting is similar to Dongfeng Automobile warriors’. The cockpit crew compartment is arranged Become, commander 1, driver 1, commander 1, staff 2 and scout 1. A variety of communication command systems are with the car.
This is the map command vehicle internal VN3 later improved. You can see the reserved space and support base for the installation of a single turret in the middle of the occupant compartment floor.
This is the late VN3 command type interior vehicle features. Combination instrument driver has been replaced by the multi-function display, switching through a switch panel on the left side of the screen display function, each component of the vehicle condition on the screen to the instrument in the form, can be connected with the vehicle command system, and accept the position information from GPS or 2 Beidou navigation system. The most important is the multi-function display switch to night vision mode, in the investigation of driving at night or light control driving. The driver was observed to be processed after the car scene by multi function display, then, both to protect the secret investigation results, but also can be used for safe driving. The right guard with multi function display is C3I (that is, command automation technology system, is to use computer will command, control, communications and intelligence of each subsystem in the integrated system is closely connected with) command systems together.
The early VN3 troop type structure, the vehicle seat is arranged: commander & infantry monitor 1, driver 1, carrying an infantry squad 8 (including the commander the driver each1), consists of 10 members.
This is the troop type interior structure chart of VN3 later improved. You can see an obvious cancelled on single turret design support in the passenger compartment floor.
This is the structure feature improved troop type vehicle interior of the late VN3. Please note that the driver position. It uses a combination of traditional instrument, rather than direct multi function display type use. The driver's side front visor integrated within a small display screen, night vision devices connected to item the driver at night using closed lamp. Multi function display with night vision observation pattern on the right side of the commander with lower levels of. Due to the use of different functions, the troop type VN3 than type VN3 command the overall technological level is far. Even the Kanwa defense think, troop type VN3 for the people's liberation army occupied type, the so called type the command VN3 is the real export version.
This is the French army equipment of VBL light armored vehicle driver position of features, we can see from the chart of vehicle interior is particularly simple, no setting engine tachometer and a button switch which is one of the few after sealing treated.
This is the French VBL vice driver side features; it is not equipped with any special electronic display device. Only the encryption stations are placed in the centre console, it is used for communication and friendly forces.
This is the internal structure of appearance similar to VN3 and the light armored vehicle, we can see the transmission and transfer case occupy a large space inside the vehicle, is affected by the engine cabin of relatively short. This is similar to the Hummer car interior layout.
This is a command vehicle driver side of the common four-wheel drive of KIA. It is different from VN3, KIA car uses a 6 speed tiptronic transmission, but it is not the night sighting system as standard cockpit.
This is the early VN3 version featured in amphibious swimming test time. Its water speed is 8 km / hour, not particularly fast, but light armored cars and Japanese and French VBL comparisons relatively advanced. Our army will be used when traveling with amphibious equipment to solve in the use of force, because our country has been in a state of unity and not yet, it’s Sea Islands Sovereignty Dispute in the South China Sea and the West and neighboring countries. This is also the reason that our people's Liberation Army of various types of equipment has almost the amphibious function.
Early VN3 version features two in amphibious swimming test.
This is a feature of early VN3 F2 vehicle road test. Please note that the driver's body is the before & after two door structure.
This is a feature of early VN3 F2 vehicle road test. Please note that the driver's body before and after the two door structure.
This is the F2 vehicle road test of the early VN3 features three. The base station is equipped with a weapon or temporary nature of the 12.7mm antiaircraft machine gun.
This is the early VN3 models F2 internal features.
F1 VN3 was produced in 2002, F2 launched VN3 in 2003 for the allies, the F2 was eliminated in the after screening, North car assemble the capable strength is crucial for F1 VN3, and in 2005 produced 4 of the test vehicle kerb mass. 1 sets of static test, 2 sets of field road test, and another one for electromagnetic compatibility test. The 2 field road test of VN3, equipped with two completely different power train. Travel more than 40000 kilometers in 1 years.
Improved version VN3 in the EMC test.
This is the early VN3 version of extreme cold field testing in the north area of our country, mainly for cold start, the vehicle lubrication, mechanical wear degree of diagnostic test vehicles in the cold area. Especially for special test reliability of the transmission system, weapon station.
Climbing vehicle test feature 1 in North car factory.
Climbing vehicle test feature 2 in North car factory.
VN3 later improved version of center of gravity test featured a cairn north areas. Improved from the early models to the later version, is not only the change of the vehicle appearance, more in the time division force, 4WD system reliability, and life before and after the lower arm made great improvement. I have many times on the status quo of China's auto industry: can design a good product, but the basic industrial bad, uneven quality of consumables, vehicle quality eventually produced is not high or even no pass. But for the whole welding military armored vehicles, and lower arm rubber sleeve high quality requirements.
VN3 later improved version of center of gravity test features 2 in North car areas.
Spare parts of each subsystem VN3 R & D share the steam warriors of the supporting service system, in the very great degree. But some special spare parts are still by their own R & D of car north, self testing and processing. This has made achieved a breakthrough on enduring high strength rubber products research and development, and the tyre central air filling , and it is successfully applied to future other wheeled vehicle models.
This is the wheel side interface features tire inflation warriors of steam.
This is the early VN3 central tire inflation system pump and pipeline feature is located in the engine compartment. Although theDongfeng Automobile of this system have been carried out to research, but the process is very slow and very difficult, and evening the whole vehicle matching, the central air charging and discharging system for quality is not stable, return the head two times improvement. North car on this system from the new development at the same time, also absorb some of the experiences and lessons of steam, finally able to complete setting assembly.
This is the final setting VN3 4WD light armored technology parameter table in 2007.
On the left side of the picture is finalized VN3 wheeled armored vehicle. It is the latest the VN3 series wheeled armored vehicle on the right side. The output power of the engine improved further, vehicle suspension improved part, and it is the export of our allies. A comparison of these two very easy to tell the difference between the two: car vehicle height, lower arm.
Lower arm of two cars have different settings.
The arm and body occupied type VN3 the left of the image has a certain angle. The structure is the same as two warriors. Action point of shock absorber is in the lower arm and body.
On the right side the exit VN3 arm and body are straight angles, the damping spring acting directly on the far, a body with the lower arm and the steering knuckle under fixed ball pin. Through these two different suspension and shock absorber settings, can judge the export type of vehicle height higher, higher mobility, bearing greater potential for modification, and has more abundant.
Rear door of VN3 is the lateral opening, pedal not off set, door trim with anti caving lining. Armor protection performance of the vehicle, can be added or improved protective material according to different conflict levels. It has a certain expansion.
We can see the VN3 as the turret basket through the rear door. The single turret electric propulsion can be used to adjust the gunner seat height. The current setting VN3 equipped with QJG91 type 14.5mm caliber machine gun. And the expansion of the avant-garde series of surface to air missile, 40mm caliber automatic gun howitzer, red arrow 73series of anti tank missile.
14.5mm caliber machine gun with square generation ventilation holes in the barrel outer stiffening beam is to cope with the high intensity fire conditions. And 7.62mm coaxial machine gun turret coordinates. The turret sides tandem set is 73mm caliber fog bomb.
Please note that the QJG at a single chamber muzzle brake. Coverage in the gun barrel and fixed point of sail cloth turret details are too bad! What a shame!
Welding details overall single turret is still acceptable, It is much better than GA06 series 4W Dand the group launched the armored, at least it is ok to prove the north car in armor on R & D strength from the side.
This is eight wheel drive armored vehicles VN1, which belong to a family car with VN3. Modified cars are including a 120mm caliber assault gun, 105mm caliber assault gun, command vehicles, mobile electronic jammer, logistics support vehicle, heavy anti tank fire support vehicles, and these are entered on the allies the export list.
This is the car product VN2 of north star (92 wheeled infantry). It is our army armored force wheel model, modified extremely rich, has been exported to the Africa, South America and other friendly countries.
BTW: Although VN3 has a lot of problems (dynamic reliability of some deficiencies, transmission system noise suppression is not sufficient, the vehicle vibration, vehicle handling the details behind western similar products), but the north car has made the first step, the main technical and tactical level, with the grade of foreign materiel smaller gap, and even some part beyond. The most important is the north car has accumulated considerable experience and technology, improve the starting point for the same vehicle R & D through research and development of this equipment, it is for the subsequent model development escort.
