2005 year. Catastrophic, unprecedented flooding in the southern states of the United States. In particular, in the city of New Orleans. The rescue operation on the flooded streets of the largest megalpolis of the state of Louisiana is carried out on the Ural-4320 trucks of the Mexican army. Miass cars passed through all the complex intricant blocks covered by the flooding streets of the Negro district - where American military trucks were powerless. And this is only one of the many episodes of the combat work "Ural-4320", in which these powerful cars visually showed their capabilities. A detailed overview of this model is in this publication.

"Ural-4320" is a three-way all-wheel drive (formula 6x6) a cargo vehicle of increased passability of the Ural Automobile Plant (Miass Cities of the Chelyabinsk Region). In a model range of an enterprise, he in the distant 1977 came to replace the Ural-375 truck.

For a number of structural elements, the Ural-4320 car is unified with the previous model - Ural-375. However, it has a more modern design that provides gravity and the best performance and technical characteristics than the Ural-375. The 4320th was the main model of the Urals auto plant until the fall of 2015 (before its official replacement for the Ural Nex.

But its production for export needs is still continuing. Since "Ural-4320" is still in demand, as a military car, in many Asian countries, Africa and Latin America. There he still continues to cause his charisma with genuine respect and real delight. And the price is quite affordable!

The truck is not in vain received an ironic nickname of "Grooming". 50-70 liters of high-octane gasoline per 100 km of way - it is a lot for the massash. Even cheap and "cassenny" gasoline. Even for a multifunctional army car, "all-pass". Therefore, the replacement for the "Urals" of a gasoline carburetor engine to a more practical dividel in the Soviet Union was thought up at the turn of the 60-70s.

However, a considerable way was passed from a clear intention to its concrete incarnation: the mass production of the Ural-4320 family started only in November 1977. By decision of the Ministry of the Automobile Industry, to develop and implement a new diesel engine with its own forces of the Mias company was recognized in impractical. Therefore, the remodesization of the "Urals": the selection of a suitable engine and gearbox, mutual fit of the power unit and the machine, - the engineers of the Ural Automobile plant were engaged together with the specialists of the flagship of Soviet Motor Station - Yaroslavl Motor Plant.

"Ural-4320" "in his element."

During the 1970-1975, a lot of work was carried out on the testing of new samples of engines and gearboxes on the experienced parties of the Ural-375 trucks. Experienced parties of prototypes, built in the versions of onboard trucks and saddle tractors, have passed the multi-stage tests in 1973-1976, and from February 1977, the stage of preparation of design documentation for mass production began. The first serial cars with the new manufacturing index "Ural-4320" came up from the conveyor of the Ural Auto Plant in November 1977.

But this was not yet a complete replacement of "Ural-375": "Obzhor" continued to be produced by an enterprise for a long time, in parallel with the new model. Ural-4320 tried to equip various diesel engines: for eight-cylinder "YAMZ-238", a more elongated engine compartment was even provided than for the six-cylinder "YAMZ-236", and for KAMAZ-740. At the same time, cars with YMZ-236 could be distinguished from cars with the "KAMAZ" an air filter engine on the right wing (due to other, more dense layout of the engine compartment). Since 2000, all "Urals-4320" began to be produced with an elongated motor compartment, regardless of the engine brand, which is installed there.

Regular orders from the Ministry of Defense, the permanent deliveries of cars to the oil and gas industry enterprises, a good export car potential contributed to the fact that in less than 10 years after the start of mass production - in 1986 - the number of "Ural-4320" released over a million units issued. The facilitated biaxial truck "Ural-43206" also owns the 4320-MU family, the production of which has mastered Miass since 1996.

In the fall of 2015, it came to the "Ural-4320" change in the model range of the Ural Nex plant - its upgraded version, with the original plastic plumage of the engine compartment, with the new generation of modern cabins of the Gazelnext type, and a number of advanced nodes and aggregates. Now all the civil versions of Ural-4320 for the domestic civil market and partially for supply by power departments are replaced by cars of the Ural Nex family. But the Ural-M series (it also "Ural-4320") is preserved specifically for export deliveries.

The immediate destination "Ural-4320" is the transportation of goods, people, towing trailers and various equipment on all types of roads and off-road (over rough terrain). Wheel formula 6x6, powerful diesel engines and solid road clearance give this car a significant off-road potential. "Ural-4320" with ease overcomes wetlands, 1.6-meter brods, 2-meter ditch and piva entering at a rise of 60%.

The chassis "Ural-4320" was used as a base for creating not only on-board and tilt cars standard or extended layout. But: for wage buses (22- or 30-seater), truck tractors and pipes, tank trucks 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 forest yields on the basis of Ural-4320, it is impossible to imagine the deforestation and harvesting of the forest in many regions of our country. Together with hydraulic manipulators, the urals forestry makes it possible to immerse and unload the forest, and other assortments, without attracting special equipment. The technical capabilities of the Ural-4320 trucks allow them to be intensive operation in the temperature range from -50 ° C to + 50 ° C, in opposite to each other, climatic conditions - from the regions of the Far North to the sandy southern deserts.

The arrangement of armored vehicles on the basis of "Ural-4320" is free, which allows you to place a variety of types of special types on the cargo platform.

The URAL-4320 cargo car is produced for more than 40 years, and considering the unification of many nodes from Ural-375, the life of the car has passed for 55. The secret of longevity is a robust design and excellent permeability. Trucks remain in demand by the army and civil services in need of similar technique.

About the huge potential of the chassis is indicated by the fact that the Ural Next appeared in 2015 is based on the nodes of the chassis of the model 4320. The cabin and the power plant underwent the update. The overall concept of the transmission remained unchanged.

History of creation

The emergence of the URAL-4320 diesel all-terrain allocation is associated with increasing gasoline prices, which was used as fuel to the Ural-375D. A new truck had a smaller fuel consumption, but he lost a little on passing a gasoline fellow.

During the mass production, the truck was upgraded several times, received new engines and gearboxes. At the same time, the appearance of the machine has changed little.

The release of various variants of Ural-4320 is currently continuing. Trucks are delivered with several types of engines, with different wheelbase and lifting capacity.

Serial production of all-terrain vehicles Ural-4320 began in 1977.

The machine is widely unobed by a number of nodes with. The parallel release of gasoline and diesel versions continued until 1992.

Design Description

The basis of the all-terrain vehicle is a frame made up of two spars selected from steel, cross-head and front buffer. The spars have an alternating section in length, providing uniform strength and stiffness of the structure.

The connection of the frame elements is made using rivets. The last crossing is equipped with a towing device. Fuel tank is installed on the frame. The filling volume is 300 liters.

The front axle is installed on longitudinal springs, supplemented by hydraulic shock absorbers. Rubber suspension stoppers are installed on the semi-axles and frame. The front end of the springs is installed on the bracket through the finger, the rear end is movably installed in the eye.

One of the sheets has a restrictive bending that prevents the removal of the sprout from the bracket. The rear suspension is balancing, spring freely walks in the eyeles installed on the bridges.

Engines

At the Ural-4320, several types of diesel engines were used. The type of engine is reflected in the modification index added to the model. "Clean" option 4320 is equipped with an atmospheric diesel engine of type KAMAZ-740.

Motor has a V-shaped arrangement of eight cylinders and develops the power of 210 hp.

The Ural-4320-31 version is characterized by the use of the 8-cylinder power unit of the YAMZ-238M2. The motor is built according to the V-shaped scheme, develops the power of 240 hp and meets Euro-0 standards. A similar diesel is installed on modifications of 4320-30. The technical characteristics of the Ural-4320-31 do not differ from the base option.


The Ural-4320-10 modification is equipped with a 180-strong diesel engine NMZ-236M2. The six-cylinder engine has a V-shaped layout, an atmospheric power system with air. The first editions of the machines with the engine NMZ-236 had a motor compartment like drips with the KAMAZ-740 engine. From the mid-2000s, the elongated compartment was used, which became standard for all versions of URAL-4320 all-terrains.

Version 4320-41 and 4320-40 received a similar diesel design, but equipped with a turbocharger and an intermediate compressed air cooler. Due to the turbine, the capacity has grown to 230 hp. Another difference is compliance with the norms of the EURO-2 exhaust (against the Euro-0 at the atmospheric motor). Fuel consumption for URAL-4320 with turbo diesel power plants is slightly lower.

Transmission

All-terrain vehicles with diesel KAMAZ were equipped with a 5-speed JMZ-141 box and a double dry-type clutch coupling. The Ural-43206 machine is equipped with a 5-speed YMZ-236U type gearbox. Clutch drives on all transmissions are equipped with a pneumatic type amplifier.

In addition to the main gearboxes on all allways, the Ural-4320 uses a two-speed dispensing box.

The torque from the box is transmitted to the gearbox with a short cardan shaft. The box includes an inter-sieve differential, equipped with a locking mechanism. The differential has an asymmetrical scheme of the moment distribution.


The control of the box and dispensing gearbox is mechanical, carried out from the driver's seat using the levers and the system. At the transfer gearbox, a power take-off box is installed, used for the actuator of the Self-drawing winch, installed under the cargo platform in the rear of the all-terrain vehicle. The winch drive is performed by three cardan shafts.

Bridges are equipped with a unified main pair, with a double torque conversion. The first step of the gearbox consists of a conical gear with a spiral shape of the tooth. The second stage includes two cylindrical boom gears. Wearase-4320 all-terrain vessels can be equipped with gearboxes with a gear ratio of 6.7 ... 8.9 (only four variants of gear ratios).

The main pair is set by a conical type differential that controls the rotation of the semi-axle.

Bridges have a passage scheme, the middle bridge is used to drive the rear axle gearbox. The semi-axes of the front axle are equipped with swivel fists equipped with hinges of equal angular velocities.

Steering and electrical system

The steering of the Ural-4320 car is equipped with a hydraulic amplifier operating in two sides. The steering column is associated with the gearbox using a cardan shaft. The column is not regulated. In the Ural-4320 all-terrestrs, an electrical system with a 24V operating voltage is used. Negative conclusions are connected to the car body.

Brake system

Brakes have a combined hydropneumatic drive. Hydraulics has two separate branches. The first manages the brakes of the front and medium bridge, the second - performs the braking of the rear axle wheels. On the rear crossbar, the frame has a crane for connecting the pneumatic trailer brakes.


The parking brake of the Ural-4320 car is installed on the output shaft of the handout. The brake is connected to the trailer brake crane mechanical tag. To improve the braking characteristics, a motor compression brake is installed that turns off the fuel supply to the nozzles.

Brake mechanisms of drum type, equipped with an automatic gap control system between overlays and a drum friction surface. Mechanisms are located directly at the wheels of the all-terrain vehicle.

Body and other equipment

Ural-4320 all-terrain vehicle is equipped with a fully metallic cabin equipped with swing doors. In the cockpit installed the adjustable driver's seat and a rigidly fixed double seat for passengers.

The interior is equipped with a ventilation system and air heating.

Cabin is installed with a metal cargo platform, equipped with a removable awning. An arcs are applied to install an arcs that are installed in the heading guides on the side sides. The platform is equipped with two folding benches along the sides and an additional detachable bench installed in the center.


Benches are designed for accommodation 27 people. The Ural-4320 truck platform has a carrying capacity of 5000 kg during operation of all coating roads. The overall dimensions of the platform have not changed compared to Ural-375d.

This is not surprising, among the factors that give the advantage of the model of the Urals 4320 - the price making it most accessible to the consumer as well as already mentioned excellent off-road qualities. Therefore, enterprises that need to carry goods to areas in which communications leave to desire the best, gladly choose this hardy truck.

At the same time, the manufacturer does not stop on the achieved and constantly developing new models of the Urals. Currently, the variants appearing in 2009 and equipped already mentioned cabins have been enjoyed considerable success.

Like his predecessor of the Ural 375, this car can be used for military needs. Armored Urals 4320 is considered a very efficient and productive army model. It is designed to transport personnel and possesses 3 class of protection, which means that it is able to protect the bullets inside the defeat from some modifications AK, not to mention the pistols.

Ural-4320 - transport with high patency, equipped with full-wheel drive and powerful tires. Its production is carried out at the automotive factory in Miass. Truck is used to transport people, cargo and trailers. Specifications allow it to overcome water obstacles to 1.6 meters deep, rs up to 2 meters deep and lifting up to 60%.

Creating a truck

The main new machine served as the 375th model. She was produced for a long time, a lot of changes were made to her design, which made Ural-375 reliable. The main disadvantage was the gasoline power plant that consumed a lot of fuel.

In the 60s, there was an idea of \u200b\u200breplacing a gasoline engine on a diesel installation. Ural engineers independently developed such an engine, but he did not receive into mass production due to the monetary deficit from the enterprise. Soon after that, the leadership of the country approved the Yaroslavl Motor Factory Center for the Development of a Diesel Power Unit. In 1969, specialists from Yaroslavl offered a new engine and gearbox to it.

The tester of the new equipment was Ural-375d. In 1970, a lot of tests were conducted, which showed the quality of the new product. Several serious problems were found, which were eliminated by 1972, after which the tests were continued. The new engine and gearbox were installed on the E4320 prototype truck.

While the new power plant was developed in Yaroslavl, in Miass, the designers were finalized the design of the Ural-375D design. In 1973, all the documentation required for production was ready. The first prototypes have come off the conveyor until the end of the same year. All three cars underwent tests with new equipment. Several insignificant improvements have been made to the machine and engine device. After that, all documentation was prepared for the start of the production of Ural-4320.

Production

In the 74th year, several more copies were built, which went to undergo tests of various complexity. After successfully passed tests, it was decided to start mass release. Serial production started in 1975.

Before the creators there was a task to make a reliable truck with high passability, because he was planned to adapt to military needs. When assembling, high-quality materials were used that ensured the high strength of the structure. The wheel formula 6x6 is responsible for the passability of off-road.

In 1978, the Kamsky Automotive Plant offered the market a new diesel power unit. Ural specialists released a small-scale party with new engines. Over the next few years, this equipment has become a priority for Miass. In 1993, a strong fire occurred at the KAMAZ plant, it was necessary to limit the production of technology. Yaroslavl equipment returned to the Ural cars.

Device

Cabin and body

The Body of the Ural-4320 car is a standard platform with sides, rear opens. For the transport of passengers, it is equipped with twisted bears. You can also install awning: in the kit there is a special web and a frame. The platform withstands the cargo to 6,855 tons, and the maximum tug weight is 11.5 tons.

The Ural-4320 cab is made of stamped metal leaves. The windshield provides a complete overview of the road to the driver. Wide rear-view mirrors are installed to assess the road situation. There are two doors to enter the salon. Cabin capacity - 3 people. The driver's seat has a convenient position adjustment system. Some versions of the transport are equipped with a bed.

In 2009, the technology of production of the cabin was changed. It was performed in accordance with modern standards, fiberglass was used for production. The internal arrangement was also changed - it became more convenient.

Specifications

The design of the Ural-4320 chassis turned out to be simple. It was done for the possibility of repairing in the field of military reminders. Different configurations were equipped with different engine power (230-250 horsepower). A 300-strong motor with a 5-speed gearbox was installed on the special scale.

To improve controllability, GUR was introduced into the design. For the launch of a tractor in the conditions of frost, a preheater was used, whose work met the requirements of Euro-3. The fuel tank accommodates 300 liters, some trucks are equipped with an additional capacity of 60 liters. Fuel consumption is 42 liters per 100 km at a speed of 60 km / h.

Transmission

The ability to move on off-road was ensured by the full drive and single-handed wheels with an automatic system for maintaining optimal tire pressure. The front suspension is addicted, installed on semi-elliptic springs. The rear suspension has a similar design.

All Ural-4320 bridges (3 pcs) leading. Front controlled wheels are equipped with shruses. One-piece clutch has a frictional drive and supplemented with a pneumatic vehicle.

The dispensing box of the Ural-4320 mechanical, has 2 steps. Its drive on the front wheels is always activated. The synchronized gearbox has 5 speeds and a blocked inter-sieve differential. Without synchronization, there are 10 speeds of the front motion and 2 rear movement speeds.

The inter-axis blocked differential Distribution Ural-4320 plays an important role. In a 1: 2 ratio, it distributes the torque between the front and rear bridges.

Reducer management passes in mechanical mode. The cardan transmission includes four shafts. The Ural-4320 leading bridges have a double main transmission, which consists of gears of conical and cylindrical types.

Brake Ural-4320

The brake system consists of two mechanisms: a two-kinnaya main and single-mounted spare. In addition, there is still an additional braking function from the exhaust system, which runs on the basis of a pneumatic actuator. Mechanical brakes Ural-4320 have drums on the distribution. The parking brake is the drums mounted on the output shaft of the dispensing box.

Engine Ural-4320

During the release of the car, several power units were used. The main two were the rest were their small modifications.

KAMAZ-740 is a compact power plant that has a crankshaft rotation frequency higher than that of Yaroslavl motors. This engine has always shown excellent results when starting on a strong frost after idle time in a few days. Its power gave the ability to use a powerful battery and starter. It has a high pressure fuel pump drive.

YAMZ-238 - Yaroslavl product, which is similar to Kamsky, but instead of the preheater has an electrofactive mechanism. A feature of the power unit is the completion of work - before joining the motor, it is necessary to let him work in a fast 2-3 minutes.

Each power unit complies with Euro-3 standards. As mentioned above, at an average speed (60 km / h), the flow of diesel - 42 liters. If the speed is reduced to 40 km / h, the flow rate is reduced to 36 liters. When moving on the soil, the flow will increase to 50-55 liters. When overcoming off-road, consumption depends on numerous movement factors. The Ural-4320 car can develop 85 km / h, and the full tank is enough to overcome the path of 1,000 km.
