Ural 4320 for internal troops dimensional drawing. Armored vehicles

2005 year. A catastrophic, unprecedented flood in the southern states of the United States. Particularly in the city of New Orleans. The rescue operation on the flooded streets of Louisiana's largest metropolis is being carried out on the Ural-4320 trucks of the Mexican army. Cars from Miass passed through all the complex intricacies of the narrow, flood-ridden streets of Negro quarters - where American military trucks were powerless. And this is just one of many episodes of the Ural-4320 combat work, in which these powerful machines clearly demonstrated their capabilities. A detailed review of this model is in this publication.

"Ural-4320" is a three-axle all-wheel drive (formula 6x6) off-road truck of the Ural Automobile Plant (Miass, Chelyabinsk Region). In the model range of the enterprise, back in 1977, he replaced the Ural-375 truck.

For a number of structural elements, the Ural-4320 car is unified with the previous model, the Ural-375. However, it has a more modern design, which provides enhanced capabilities and better performance characteristics than the Ural-375. The 4320th was the main model of the Ural Automobile Plant until the fall of 2015 (before its official replacement with the Ural Next.

But its production for export needs is still ongoing. Since the Ural-4320 is still in demand, as a military vehicle, in many countries in Asia, Africa and Latin America. There, to this day, he continues to evoke genuine respect and real delight with his charisma. And the price is quite affordable!

The truck received the ironic nickname "Glutton" for a reason. 50-70 liters of high-octane gasoline per 100 kilometers is a lot for a mass-produced car. Even cheap and "state-owned" gasoline. Even for a multifunctional army vehicle - "all-terrain vehicle". Therefore, the Soviet Union thought about replacing a gasoline carburetor engine with a more practical diesel engine in the Urals at the turn of the 60-70s.

However, a long way has been passed from a clear intention to its concrete implementation: serial production of the Ural-4320 family started only in November 1977. According to the decision of the Ministry of Automotive Industry, it was considered inexpedient to develop and implement a new diesel engine by the Miass enterprise on its own. Therefore, the remotorization of the Urals: the selection of a suitable engine and gearbox, the mutual adjustment of the power unit and the machine, the engineers of the Ural Automobile Plant were engaged in together with the specialists of the flagship of the Soviet engine building, the Yaroslavl Motor Plant.

"Ural-4320" "in its element."

During 1970-1975, a lot of work was done to test new models of engines and gearboxes on experimental batches of Ural-375 trucks. Pilot batches of prototypes, built in variants of flatbed trucks and truck tractors, passed multi-stage tests in 1973-1976, and from February 1977, the stage of preparing design documentation for serial production began. The first mass-produced cars with the new Ural-4320 production index rolled off the assembly line of the Ural Automobile Plant in November 1977.

But this was not yet a complete replacement for the Ural-375: the Glutton continued to be produced by the enterprise for many years, in parallel with the new model. They tried to equip the Ural-4320 with different diesel engines: for the eight-cylinder YaMZ-238, a more extended engine compartment was even provided than for the six-cylinder YaMZ-236 and for the KamAZ-740. At the same time, cars with YaMZ-236 could be distinguished from cars with a KamAZ engine by the air filter on the right wing (due to a different, denser layout of the engine compartment). Since 2000, all Ural-4320s have been produced with an extended engine compartment, regardless of the brand of engine that is installed there.

Regular orders from the Ministry of Defense, constant deliveries of vehicles to oil and gas enterprises, a good export potential of the car contributed to the fact that in less than 10 years after the start of mass production - in 1986 - the number of Urals-4320 produced exceeded one million units. The Ural-43206 lightweight biaxial truck, the production of which has been mastered in Miass since 1996, also belongs to the 4320th family.

In the fall of 2015, the Ural-4320 was replaced in the model range of the Ural Next plant - its modernized version, with the original plastic plumage of the engine compartment, with a new generation of modern cabs of the GAZelNext type, and a number of improved components and assemblies. Now all civilian versions of the Ural-4320 for the domestic civilian market and partially for deliveries to law enforcement agencies have been replaced by cars of the Ural Next family. But the Ural-M series (aka Ural-4320) is retained specifically for export deliveries.

The immediate purpose of the Ural-4320 is the transportation of goods, people, towing trailers and various equipment on all types of roads and off-road (cross-country). Wheel formula 6x6, powerful diesel engines and solid ground clearance give this car a significant off-road potential. "Ural-4320" easily overcomes wetlands, 1.6-meter fords, 2-meter ditches and ditches, drives uphill to 60%.

The Ural-4320 chassis was used as a base for the creation of not only flatbed and tilt cars of a standard or extended layout. But also: for shift buses (22- or 30-seater), truck tractors and pipe carriers, tankers and tankers, installations and special equipment for oil and gas production, road and municipal equipment, fire protection and, of course, for the needs of the armed forces.

Without timber trucks on the basis of "Ural-4320" it is impossible to imagine felling and logging in many regions of our country. Together with hydraulic manipulators, URAL timber trucks allow you to load and unload timber and other assortment without the involvement of special equipment. The technical capabilities of Ural-4320 trucks allow their intensive operation in the temperature range from -50°C to +50°C, in opposite climatic conditions - from the Far North to the sandy southern deserts.

The alternating current generator "G-288E" has a power of 1000 W and works in conjunction with a non-contact voltage regulator "1112.3702". Starter "CT-142-LS" - electromagnetic inclusion, with a maximum power of 8.2 kW.

Trucks "Ural-4320" were equipped with a metal two-door cab, designed for a driver and two passengers. The classic, traditional cabin of the Urals has been produced for fifty years now, and, of course, the comfort indicators in it are infinitely far from modern ones. Although: the driver's seat is adjustable, there are ventilation and heating systems, there is a power steering, it is possible to equip the cabin with a berth. If desired, an air conditioner, an independent heater and a Webasto preheater can be installed on the Ural-4320.

In order to create more comfortable conditions for movement and better safety, since the spring of 2009, successful experiments have been undertaken to equip the newly developed Urals with new-style cabins. This is a cabover cabin with fiberglass plumage, manufactured under license from Iveco. It has three separate anatomical chairs with headrests, armrests, seat belts.

In interior decoration and cladding - modern materials that provide good noise and heat insulation, a steering wheel with lower spokes (not overlapping instruments). All controls are arranged in close proximity to the driver, the parking brake and transfer case control are pneumatic (which made it possible to remove the levers from the passenger compartment). The new cab provides comfortable working conditions for the driver. But the charisma of the external appearance of the car, of course, completely takes away.

Overview of serial modifications "Ural-4320"

As part of the Ural-4320 family, the following vehicle modifications were made on the assembly line of the Miass plant:

• Truck flatbed and tilt "Ural-43202-0351-31" general transport purpose with a wooden platform;
• Truck tractors "Ural-4420-10" and "Ural-4420-31", designed for towing special semi-trailers on all types of roads and rough terrain;
• Tractors "Ural-44202-0311-31", also designed for towing semi-trailers on all types of roads and off-road;
• The truck tractor "Ural-44202-0612-30" is designed for towing semi-trailers and various equipment on airfields and other flat areas;
• "Ural-4320-0911-30" - with an extended base;
• "Ural-4320-0611-10" and "Ural-4320-0611-31" - also with a wooden loading platform and an awning.

On the basis of the Ural-4320 vehicles of these modifications, chassis with similar technical characteristics were also produced, for van bodies, shift buses, and various special equipment. Within the same modification, various options are possible: by the presence of a winch, or without it; according to the location of the spare wheel holder: behind the cab or at the rear of the frame, with a vertical or horizontal arrangement; or without holder (with temporary technological fastening on the frame); with mechanical power take-offs from the gearbox (KM) and transfer case, or without them; with the presence of a towing device for towing trailers, or without it.

During the 2000s, on the basis of the Ural-4320, four armored army vehicle modifications were demonstrated to the general public. This is "Ural-4320-09-31"; "Ural-4320-0010-31" (or "Ural-E4320D-31"); "Ural-4320VV". As well as the Kasspir MK6 armored vehicle, which is manufactured on the Ural-4320 chassis by the Indian company Mahindra and Mahindra, at its plant in Prithla, Haryana. All these vehicles have solid ballistic and mine protection.

Cabins, including their rear walls, roofs and floors, are made of solid armored steel sheets, equipped with armored glass with loopholes for firing; powerful safe-type doors with locks with internal blocking. The roof has a hatch that can be used as a machine gun nest. The fuel tank and battery box are also armored.

Armored vehicle "Ural-4320VV".

It is planned to use a wide range of special equipment in these armored vehicles: night vision devices, radiation and chemical reconnaissance, army radio stations of various types, filter-ventilation installations, etc. It is also possible to install an armored module in the back to accommodate personnel (about 15-20 fighters). The layout of armored vehicles based on the Ural-4320 is free, which allows you to place a variety of types of special modules on the cargo platform.

New armored car model Ural-VV developed by order of the command of the internal troops, which is reflected in the letters "VV" present in the title.

According to reports, the customer independently developed technical requirements for. They take into account the experience of using armored and unprotected vehicles in recent conflicts, the specifics of the work of internal troops, etc. In the course of analyzing the capabilities of the industry and the realities of combat work, the specialists of the Ministry of Internal Affairs excluded some points from the requirements for a new armored vehicle, and also added new ones.

Among other requirements for the car Ural-VV Of greatest interest are two related to the layout of the armored hull. The internal troops wished to receive equipment with a single armored corps. In accordance with the terms of reference, the driver's cab and the troop compartment should be a single volume. The second notable requirement is the presence of a large number of hatches. To reduce the time required to leave the car, the customer demanded to equip it with a large number of doors and hatches.

The development of an armored car of a new model was entrusted to an automobile plant "Ural"(Miass) and the Moscow Research Institute of Steel. The first enterprise was responsible for the creation of the chassis and related units, the second - for the armored hull. First armored car Ural-VV was shown in September last year, at the exhibition Russian Arms Expo-2013 in Nizhny Tagil. The demonstration of the first instance and the publication of some data about it allow us to form an opinion about a promising armored vehicle.

As a basis for an armored car Ural-VV the Ural-4320 truck was chosen, which is in mass production and has proven itself to be a good car in its class. The all-wheel drive three-axle chassis is equipped with a YaMZ-536 diesel engine with a power of about 310 hp. Such an engine and chassis is said to provide high performance both on the highway and on rough terrain.

Armored car body Ural-VV assembled from metal sheets of various thicknesses and is able to protect the crew from bullets and shrapnel, as well as from. The frontal parts of the hull and glass provide protection at the level of class 6 according to domestic standards, the sides - class 5. The engine compartment has its own armored casing, providing class 3 protection. The protection of the crew from the explosion of two kilograms of TNT is declared. An interesting feature of the new armored car is the additional anti-fragmentation protection of the engine and gearbox placed under them. The experience of operating equipment of various classes showed the need for the use of such parts.

For landing and leaving the car has several doors. Two are located in front of the habitable volume, one is on the starboard side, and there is a wide double door in the stern sheet. For convenience, the rear doors are equipped with a folding ladder with a pneumatic cylinder. If necessary, it can be lowered manually. The voluminous cargo-passenger compartment allows the armored car Ural-VV carry up to 17 people, including the driver (according to other sources, there are only 13 seats). Fighters are placed on seats installed along the sides. According to some reports, the armored car that was demonstrated in Nizhny Tagil did not have seats installed that absorb some of the energy of the mine explosion. Perhaps in the future the armored car will receive similar equipment.

When developing a new armored car, not only the requirements regarding driving performance or the level of protection were taken into account. To create comfortable conditions, the habitable volume of the machine Ural-VV equipped with an air conditioning system, a heater and a number of other equipment that affects the convenience of being in an armored car. It should be noted that these devices are declared as standard.

Armored car Ural-VV does not have its own weapons, however, if necessary, the crew can fire from personal weapons through the loopholes. All glasses have one such device. Permissible angles of fire, apparently, allow you to attack targets in any direction.

big party Ural-VV will go to some parts, where it will partially replace the unprotected trucks and armored personnel carriers available there. The armored vehicles ordered by the Ministry of the Interior have an interesting legal feature that will facilitate their operation. Unlike armored personnel carriers and other equipment of several classes, armored cars Ural-VV or similar vehicles are full participants in the road traffic and therefore can move independently and without any escort along the roads, which can significantly speed up the transfer of personnel.

At present, preliminary tests of a prototype of a protected vehicle with a one-volume body "Ural-VV" are being completed. It was developed on an initiative basis in accordance with the terms of reference approved by the Commander-in-Chief of the Internal Troops of the Ministry of Internal Affairs of Russia. In the near future, "Ural-VV" will enter the state tests.

The specifics of the performance of service and combat tasks by units of the Internal Troops of the Ministry of Internal Affairs in recent years involves the frequent transfer of personnel, military and other cargo in the face of the threat of attacks on columns of illegal gangs, movement along sections of roads where mine-explosive barriers or individual explosive devices can be installed . In these cases, the use of multi-purpose army vehicles is associated with a high risk to the lives of military personnel and the loss of cargo being transported, which is sometimes tantamount to failure to complete a combat mission. The use of infantry fighting vehicles or armored personnel carriers for solving such tasks, especially in peacetime, has a number of limitations related to the provision of escort of these vehicles when driving on public roads, possible irritation of the local population, etc., which reduces the efficiency of the units and divisions.

Ural-4320 car with local cab reservation.

As the experience of military conflicts and counter-terrorist operations has shown, the solution of the above tasks is most effectively carried out using protected army multi-purpose vehicles. They have high mobility and can move with the necessary level of protection both on public roads and on rough terrain. At the same time, high cross-country ability is important, since the choice of routes for the movement of convoys that are not tied to public roads reduces the risk of vehicles falling into ambushes or undermining an explosive device, which are usually arranged on such roads.

For many decades, military vehicles with the Ural brand have occupied a leading position in terms of cross-country ability and reliability in the armies of many states. Therefore, the creation of a protected car based on a used chassis has become a reasonable and justified decision. Over the past decade, a number of research and development works have been carried out, which made it possible to significantly increase the level of protection of military vehicles from being hit by fire from the main types of small arms and from mines and land mines.

Step by step, optimal methods were developed to protect the vital systems of the vehicle and the personnel and cargo transported in it. At the initial stage, in order to reduce the time for retrofitting vehicles with armor protection, the design of mounted armor for Ural-4320 vehicles was developed. Armored screens were bolted to the outer surfaces of the cab. Such a booking scheme is less laborious, however, the insufficient load-bearing capacity of the cabin structure led to sagging of the doors, and sometimes to their separation. The complex shape of the outer surfaces of the cabin did not allow for a high level of crew protection, which did not exceed class 3 according to GOST R 50963-96 or level 1 according to STANAG 4569.

The scheme in which armored screens were installed inside the cabin became more effective. In accordance with it, the cabin was dismantled, the frame, door hinges, window openings, cabin mounts, etc. were finalized. The design of the cab has been significantly strengthened, but at the same time the appearance of a production car has been preserved, which is often confusing and deprives the enemy attacking such vehicles from ambushes of the element of surprise. The built-in local armor protection provided the 5th protection class in accordance with the requirements of GOST R 50963-96 (2nd level according to STANAG 4569). In parallel with the study of schemes and methods for protecting the cab of cars, work was carried out to create special armored cabs, hulls and functional modules.

Tests on the impact of bullets of the main types of small arms and shell fragments, as well as the experience of the combat use of vehicles with local armor protection, made it possible to determine the level of their protection and identify weaknesses in the design. Penetration of the material of the main armor (steel armor and armored glass) was not identified, but the main problems of local armor were the difficulties in providing protection around the perimeter of the openings of windows, doors and hatches, at the joints of armored screens, as well as at the places of laying pipelines and electrical wiring.

Armored vehicles "Ural" family "Bear".

The next step was the creation of all-welded armored cabins. During the development of this direction, armored cabs for Ural-432009-31 and Ural-532303 vehicles were proposed. They are made according to the 5th protection class in accordance with the requirements of GOST R 50963-96 (2nd level according to STANAG 4569). They passed the tests when fired from an SVD rifle with B-32 armor-piercing bullets from a distance of 300 m and when fired from an AKM machine gun with PS bullets with a TUS (heat-strengthened core) of 7.62 mm caliber from a distance of 5 m. air conditioning ducts were provided by installing barbettes (protective joint strips).

When using all-welded armored cabs, the curb weight of the vehicle increases less than when introducing a local cab reservation scheme, since in the latter case the serial cab itself is the carrier system, in the design of which reinforcement elements are additionally introduced and protective armored screens are installed. An armored cabin, as an all-welded steel shell, is both a load-bearing and a protective structure, therefore, in order to achieve the same level of protection, in terms of mass indicators, it is preferable to use an all-welded armored cabin.

Significant disadvantages of local booking are also the inability to book the entire cabin area, the presence of a large number of weak points at the joints of protection elements, the high labor intensity and complexity of retrofitting a serial cabin. At the same time, it should be taken into account that the main limitation for increasing the level of protection for vehicles with various armor options is an unacceptable increase in the load on the front axle, which has a significant impact on the off-road capability. On cabover machines, such an increase in weight also becomes critical in terms of operational reliability, controllability and braking properties.

Based on the experience gained in the development of various vehicle armor schemes, test results and combat use, the designers of the Ural Automobile Plant, together with specialists from the Research Institute of Steel, in the period 2007-2010. by order of the Ministry of Defense of the Russian Federation, work was carried out to create a unified family of multi-purpose armored vehicles based on the Ural military multi-purpose vehicles with protection level according to class 6a according to GOST R 50963-96 (level 3 according to STANAG 4569). This ROC received the code name "Bear".

As part of this work, prototypes of multi-purpose armored vehicles were created:

- Ural-43206-0010 with a 4×4 wheel formula with an armored cab;

– Ural-4320-0010-31 with a 6×6 wheel formula with an armored cab and an armored functional module on the loading platform;

- Ural-532341-1010 with an 8 × 8 wheel arrangement with an armored cab and an armored functional module on the frame.

On vehicles of the Medved family, a frame-panel design of armored cabs was used. The main protective panels were made of armor steel sheets with the possibility of replacing the armor steel with ceramic composite armor mounted on an aluminum alloy substrate. Cabin glazing was made of bulletproof glass providing protection according to class 6a GOST R 50963-96 (level 3 according to STANAG 4569). During tests for bulletproof resistance, for the first time, it was possible to achieve a complete absence of penetrations along the door contour and panel joints. Tests for mine resistance showed satisfactory security of the crew when a charge was detonated under a wheel weighing up to 1 kg in TNT equivalent. A further set of tests of the Medved vehicles for mine resistance demonstrated the potential for increasing the resistance of their design to the high-explosive effects of undermining a charge weighing 6-8 kg in TNT equivalent.

General view of the armored car "Ural-VV".

In 2013, in accordance with the terms of reference of the Main Command of the Internal Troops of the Ministry of Internal Affairs of Russia, an armored vehicle with a one-volume body was created on the basis of the Ural-4320-70 army vehicle, which received the designation "Ural-VV". The machine was developed under the guidance of O.R. Yakupov and chief designer for special projects V.V. Dmitriev.

Armored car "Ural-VV" is used as a vehicle by units of internal troops of the Ministry of Internal Affairs of Russia to transport personnel or cargo, protect the crew and cargo from firearms and damaging factors of explosive devices. The machine is made on the basis of the chassis of the Ural-4320-70 serial vehicle, which makes it possible to increase the unification and reduce the cost of spare parts and operating materials used in parts and connections, to simplify and reduce the time for driver training.

One of the main features of the new Ural-VV protected vehicle is that no imported components are used in its design. With some countries trying to force the world community to adhere to political views in line with their worldview through the imposition of economic sanctions, the refusal to use imported components can play a decisive role in ensuring that machines are delivered to customers on time.

Another advantage of the Ural-VV armored car is the possibility of its operation on public roads without any restrictions. From the base Ural-4320-70, the Ural-VV armored vehicle inherited its unsurpassed off-road capability. High mobility is provided by a powerful diesel 6-cylinder V-engine YaMZ-6565 or in-line YaMZ-536. Each of them is capable of developing a maximum power of 270 hp.

Forced locking of interaxal and interwheel differentials provides the machine with high cross-country ability. "Ural-VV" confidently moves both on snow up to 1 m deep and on sandy-desert terrain, overcomes water obstacles to ford or flooded terrain up to 1.9 m deep, mountain passes 3000 m high, steep ascents, descents and slopes. This allows him to bypass dangerous sections of roads where ambushes or the installation of minefields are possible. If a collision with the enemy cannot be avoided, then the armored corps is able to protect the crew, transported personnel or cargo from fire from the main types of small arms, as well as from detonation on various explosive devices. The front projection of the machine and all the glazing create protection according to class 6a according to GOST R 50963-96 (level 3 according to STANAG 4569), i.e. will keep hits of B-32 armor-piercing bullets fired from an SVD rifle from any, even the most insignificant distance. The remaining projections of the hull and the roof provide protection according to class 5 according to GOST R 50963-96 (level 2 according to STANAG 4569), i.e. withstand hits of 7.62 mm bullets with a heat-strengthened armor-piercing core fired from an AKM assault rifle from any distance.

The interior of the car "Ural-VV" is equipped with anti-traumatic seats.

For the convenience of landing in the stern there is a swing door with a folding ladder.

When developing a single-volume armored hull, several options for its design were worked out. Ultimately, after numerous tests and based on the experience of previous R&D, the choice was made in favor of an all-welded armored hull design, in which not only the frame, but also the armored plates themselves perceive operational loads. At the same time, the mass of the body does not exceed the permissible norms.

The hull design meets the requirements for ergonomic crew accommodation, protection, maintaining transport dimensions and weight distribution along the vehicle axles. The case is made according to a modular scheme, which makes it possible to make the process of production, assembly and maintenance more technological. The front module is a control compartment (cabin) and is joined to the personnel accommodation module along a special reinforced flange. Outside, the joint is closed with protective overlays.

From the inside, the armored hull is covered with anti-fragmentation protection (AOP), which is a package of special materials based on domestic aramid fabrics. It should be noted that domestic protective materials have a smaller mass and better protective properties in a standard protective package compared to imported ones. In addition, AOP plays the role of thermal and sound insulation, and also gives a more aesthetic appearance to the interior of the car.

High anti-mine resistance is provided by a special shape of the bottom of the armored hull, its high location above ground level and the installation of special anti-traumatic seats with seat belts.

"Ural-VV" is capable of carrying 17 fully equipped fighters, including the driver, or up to 3 tons of cargo. Four doors are equipped for boarding and disembarking the crew and troops in the armored hull: two on the sides of the cabin for the driver and senior vehicle, one more door on the starboard side of the personnel accommodation module and aft hinged door with a removable central beam. Under the stern door there is a ladder, reclining with the help of a pneumatic system or manually.

For firing from the individual weapons of the crew and the landing force, closing loopholes are made in all bulletproof glasses: one in the windshield on the right side of the older vehicle, five on the starboard side, four on the port side and two in the windows of the hinged door in the stern. There are six hatches in the roof, closed with armored covers. Hatches can be used for firing individual weapons or as emergency exits. At the request of the customer, a remotely controlled combat module with weapons can be mounted on the roof of the hull or a rotating shoulder strap with an opening wide hatch can be equipped. On the chase, it is allowed to install a heavy machine gun or an automatic grenade launcher.

The main technical characteristics of the armored vehicle "Ural-VV"

"Ural-VV" has high operational characteristics. It is designed for operation in areas with a temperate climate with garageless storage, at ambient temperatures from -45'C to +45'C (maximum operating temperatures - from -50 to +50'C), relative humidity up to 98% at ambient temperature +25°С, air dust content not more than 1.5 g/mВІ, wind speed up to 20 m/s, in areas at absolute altitudes up to 2500 m with the possibility of overcoming individual passes up to 3000 m high. In order to reduce crew fatigue and creating comfortable conditions for personnel when working in hot climatic conditions, the machine is equipped with an air conditioning system in the cabin.

According to experts, the Ural-VV armored vehicle in the future will become the basis for a whole family of highly unified tactical protected vehicles with various wheel formulas in all law enforcement agencies. A large useful reserved volume of the vehicle provides for the installation of various equipment, apparatus, communications and weapons systems. ¦
