"Ural-4320" with the engine JAMZ: TTX. "Ural-4320" military

Truck production of the Ural automobile plant has a universal purpose. It was designed for the transportation of people and freight. The performance characteristics of “Ural-4320” allow you to overcome impassable places at full load. This factor contributed to the wide use of machines in the military and in regions with difficult climatic conditions. The first model of vehicle released in 1977. Actually the car is an improved copy of car “Ural-375”, which was produced for military purposes.

Exterior

According to the performance characteristics of “Ural-4320" it has a body of a metal platform and a tailgate. The vehicle is equipped with benches, tent and arches of removable type. There are also incremental lattice side. The standard package includes a triple cabin, assembled from thick-walled sheet metal fabricated by stamping. Careful glazing and rear view mirrors give you the opportunity to monitor the situation on the road and increase visibility.

Structurally, the body is made in the form of short overhangs, which improves the rate of patency. Curb weight of the truck is 8.2 tons. Load weight – to 67.8 tons with a towing capability of 11 tons.

Performance characteristics of “Ural-4320" of the military with the engine YAMZ

One of the variations of the power plant on the truck was the engine YAMZ in various versions. It is a four-stroke engine with a electro-flare device for start. A feature of the powertrain is the point that before the final completion of the work of a few moments it should at idle.

The Motor fully complies with European standards (Euro-3). Tank capacity for fuel is about three hundred gallons (some models are equipped with additional tanks for 60 litres). Consumption of diesel fuel per hundred kilometers around 30 to 40 liters, depending on the speed and availability of a hitch. The maximum rate of speed of the car – 85 kilometers per hour.

Other options of the power plant

Developing the performance characteristics of the engine “Ural-4320" of the manufacturers have provided the ability to install multiple types of motors. Among them are the following variations:

• Setting the KAMAZ-740.10 – power of 230 horse powers, volume of 10.85 liters, has 8 cylinders, and it operates on diesel fuel;
• YAMZ-226 – runs on diesel, the power is 180 horsepower;
• YAMZ-236 НЕ2 has a volume of 11.15 liters, the power of 230 horses, turbocharged, four bars;
• In addition, mounted modification of the Yaroslavl motor plant index 238-M2 236-БЕ2, 7601. They differ in horsepower (240, 250, and 300, respectively).

In addition, the performance characteristics of “Ural-4320” with the engine YAMZ include the installation of a hydraulic amplifier, glow and compliance with motor standard «Euro 3”.

Technical parameters

The Brake Assembly includes a primary dual-circuit system and refill with one circuit. Plus the brake is actuated by a pneumatic actuator from the exhaust flue gases. This node type mechanical with placed the reel on the dispenser box (RK) is very effective. Parking brake – a drum mounted on the output shaft of the RK.

The performance characteristics of “Ural-4320” designed for a wheel formula 6*6. High permeability provide a single wheel equipped with an autoptical air chambers. Front suspension – dependent, has shock absorbers and springs-poluulybki. The rear node is also dependent of the type with leaf springs and torque rods. The truck three axle, they are all wheel drive, front wheels are equipped with constant velocity joints. The clutch unit has a friction drive, a pneumatic amplifier, disc with diaphragm spring exhaust.

Cabin and overall performance

The Presented truck is equipped with a two-door cabin, it is made entirely of metal and designed for three people. The driver's seat is adjustable, there is a ventilation system, upgraded variations are equipped with a sleeping bag. After 2009 the working conditions of the driver has improved significantly. The new cabin has more comfort, the hood is made of fiberglass and original style.

The following are the main dimensions that provide the performance characteristics of “Ural-4320”

• Length/width/height (m) – 7,36/2,5/2,71 at awning height of 2.87 meters.
• Net Weight (kg) – 8,57.
• Maximum weight of towbar (t) – 7,0.
• Wheel Track (m) – 2,0.
• Road Clearance (cm) – 40.
• Number of seats on the platform – 24.

It is Worth noting that the truck has a solid power reserve that allows to overcome without refueling more than one hundred kilometers.

Tactical indicators

The performance characteristics of “Ural-4320" of the military in the tactical plan have the following features:

• Overcoming the pond to Wade (depth) – half a meter.
• The Intersection of marshland – similarly.
• Ditches and trenches (depth) – up to 2 meters.
• Maximum lifting height – 60°.
• Minimum turning radius – 11,4meters.
• Maximum height above sea level for normal operation – 4 thousand 650 meters.

Structurally, a powerful truck designed to protect the cab and driver from dirt when riding off-road (powerplant located in the front, the hood is lifted upward, and the sides are set wide flat wings).

The performance characteristics of “Ural-4320” allow it to operate in harsh climatic conditions, with maximum humidity up to 98°. Temperature range is from + to –50 degrees. Permitted outside storage of the machine. Withstanding the maximum force of the wind is 20 meters per second, and a dust – 1,5 Cuba.

Current modifications

During the issue under consideration from the Ural truck manufacturers, has developed several modifications, the main difference between them lies in the power of the power plant. The most popular are these models:

1. “Ural-4320-01” – has superior cabin, platform and checkpoint. Release year – 1986.
2. Similar modifications to the engine YAMZ with a capacity of 180 horses, and a truck with extended wheelbase and patency rates.
3. Performance characteristics of “Ural-4320-31" differ from its predecessor by the presence of eight-cylinder powertrain (YAMZ) with a capacity of 240 horsepower and improved increased power density. Released car in 1994.
4. Model 4320-41 – YAMZ-236НЕ2 (230 HP), year - 2002, compliance, "2 Euro".
5. Option 4320-40 — a version of the previous car, equipped with extended base.
6. Modification 4320-44 – added cabin, improved comfort (GV – 2009).
7. Long-baseline “Ural-4320-45”.

Conclusion

It is Possible to note several points that popularized considered a truck in the army and for civilian purposes. First, “Ural-4320” is not afraid of absolutely no off-road, has a high permeability and capacity. Second, he is unpretentious in maintenance, operation and repair. In addition, this machine is versatile, capable of carrying military, civilian cargo, heavy hitch and about 30-35 people.

It is Worth noting that the manufacturers are constantly working to improve the "Ural". Machine for the army is considered to be effective and productive vehicle. In addition, the truck has great power, armored variations are intended to protect personnel from the defeat of charges from light and medium small arms (the third category of protection). In the civilian use of machine irreplaceable for the Northern regions and regions with difficult terrain.
