Multipurpose vehicle


In previous parts the story about the birth and development of KamAZ-4310, the operation of a tactical truck in the Soviet Army, we bypassed. Meanwhile, the 4310 and its modifications were widespread in the armed forces, although they were noticeably inferior to the original military Ural-4320.

In addition to onboard KamAZ trucks and artillery tractors (guns up to 7 tons), 4410 truck tractors worked in the army for towing 15-ton semi-trailers. From the very moment the military truck appeared from Naberezhnye Chelny, a pressurized K-4310 van body was developed for it. The van was a modernized extended version of the Ural analogue of the K-4320. The body had a payload of about 5 kg and a dead weight of 800 kg.

The KamAZ-4310 platform was widely used in the signal troops. The first was the R-417 Baget-1 mobile digital tropospheric radio relay station, developed in the early 1980s. To operate in rough and mountainous terrain, the R-423-1 Brig-1 station was later created, which also received a chassis from Naberezhnye Chelny as a mobile platform.

KamAZ-4310 also carried SPN-4 noise jamming systems, R-934B automated jamming stations, which allow detecting and suppressing aviation radio communication facilities. Since 1986, the 35N6 antenna installation and the hardware of the Kasta-2E1 low-altitude radar station have been mounted on trucks. The station, located on two KamAZ trucks, made it possible to detect aircraft in the air at a distance of up to 105 km and was used by the air defense forces, coastal and border guards.

In the interests of the rear


For the needs of military repairmen, the KamAZ-4310 (and later the more powerful 43101) became a mobile platform for the PARM-1AM, PARM-3A / 3M and PRM SG workshops, MS-DA welding units and ATO-Z signal service repair stations.

The relatively long platform of a military truck and a carrying capacity of 5 tons were excellent for accommodating tank trucks for various purposes.

We will not separately load readers with a cumbersome abbreviation. We only note that on the 4310 platform they built oil tankers with a 5,5-cc tank for diesel fuel (gasoline, kerosene) and a 300-liter tank for oil. A simpler machine with a 7-cc tank exclusively for motor fuel is still working in the army. For the RChBZ troops, KamAZ-4310 was built with a multi-purpose auto-filling station ARS-14K to solve a wide range of tasks - degassing, disinfection and deactivation of equipment, buildings and terrain. Smoke screens were supposed to be installed in the troops by the TDA-2K vehicle, capable of masking objects up to 1 km long.

The light technical assistance vehicle MTP-A2 was developed at 21 NIIII in the late 1980s. But a tow truck based on KamAZ-4310 went into production only in the early 1990s. The damaged equipment MTP-A2 could be transported in a semi-submerged state. The MTP-A4320 evacuator became similar (only on the Ural-2.1 base). That is, two identical highly specialized technical assistance vehicles on different platforms are currently serving in the army.

Fighting qualities


KamAZ received the baptism of fire in the mountains of Afghanistan. At the same time, not only all-wheel drive trucks, but also completely civilian vehicles of the 53rd series, took part in the conflict.

KamAZ trucks have deservedly become popular and beloved vehicles among drivers. First of all, the comfortable cab with a berth was highly appreciated. The army did not know such a luxury before - the jobs of Uralov and ZiL were both closer and simpler. Few problems arose with difficult-to-operate KamAZ-740 diesel engines, annoying leaks of coolant and engine oil.

Also in Afghanistan, there was a weak mine resistance of cabover trucks.

After the war, in the late 90s, the Russian army conducted comparative tests of KamAZ-4310 and Ural-4320 for detonation with an anti-tank mine. Similar mannequins were planted in the cabins. And they detonated a mine with 6,5 kg of explosives under the front left wheel. In the case of the 4310, this was fatal to the driver. After the explosion, parts of the dummy were in a funnel, the wheel arch was torn apart, and fragments riddled the roof of the cab. In the video report from the tests, you can hear the following eerie thesis:

"There is no living space for the driver."

An embarrassment occurred with an all-terrain vehicle from Miass during similar tests. The truck was sent to the mine in second gear with the steering wheel fixed, but the detonator was triggered only by the last wheel on the left side. The wheel was blown off the hub by an explosion, but the Ural-4320 was able to continue moving on its own.

This allowed for another crash test. Only now the truck with the dummy was being pulled by a cable. This time everything worked properly. And after the mine detonated at the dummy, even a foot on the accelerator pedal remained. In fact, only minor contusions and minor injuries threatened the passenger and the driver of the bonneted truck.

The cabover layout of KamAZ (associated primarily with its unification with civilian vehicles) significantly weakened the protection against frontal shelling.

Bullets falling below the windshield line freely penetrated the cockpit and hit the crew.

Ural-4320 to a certain extent was deprived of this drawback.

However, both cabins from the very moment of development had the main drawback - the impossibility of integrated booking.

The local armor had to be hung on the cockpit panels. That increased the final mass and was not particularly effective.

Eternal competitors in the sand


And another one история comparison of competitors from Miass and Naberezhnye Chelny.

Six years ago, MSTU "MAMI" tested the support cross-country ability of three all-terrain vehicles - KamAZ-4350 (4x4), KamAZ-43114 (6x6) and Ural-4320-31 (6x6). For the purity of the experiment, all trucks were shod in the same Kama-1260 tires. All machines were tested on dry free-flowing sand (moisture content 6% and burial depth up to 3 m).
And the two-axle 4-ton KamAZ, as expected, did not perform in the best way. Despite the highest power density - 20,3 liters. from. per ton. KamAZ-4350 had a maximum specific tire load - 7,7 t / m3.

The problem of the three-axle 6-ton KamAZ was the overloaded front axle, which accounts for up to 35% of the vehicle's weight when fully loaded. This was the reason for the last third place in all tests.

In the bonneted Urals (similar carrying capacity), the front wheels accounted for about 31% of the mass. It would seem that this is not the most cardinal difference. But this (including) allowed the all-terrain vehicle from Miass to win all trials. And maintain the highest speed on the sand - 30 km / h.

Two-axle KamAZ on loose sand did not accelerate more than 27,5 km / h. And the 43114 was generally able to squeeze out only 26,9 km / h.

The Ural also surpassed its competitors in traction and coupling properties, that is, traction on the hook.

In search of perfection, the testers carried out a series of experiments with different tire pressures. As expected, it turned out that the lower the pressure (within reasonable limits, of course), the higher the pull on the hook.

Ural-4320-31 in this discipline, with a slight advantage, defeated all-terrain vehicles from Naberezhnye Chelny. The pull on the hook in the Urals was 1,8% higher than that of a two-axle all-terrain vehicle, and 3,6% higher than that of a three-axle one.

"Mustang" to order


All comparisons with the Urals and combat experience did not benefit the KamAZ all-terrain vehicles.

And over time, the Ministry of Defense transferred these vehicles from the tactical military level to the operational one. Only the Ural-4320 and its modifications remained in the role of a tactical truck.

In the late 1980s, the military formulated requirements for new combat KamAZ trucks. In accordance with them, the army waited for two-, three- and four-axle all-terrain vehicles with independent suspension, hydromechanical transmission, more powerful engines and with the ability to overcome a ford up to 1,75 meters deep. (Previously it was 1,5 meters.)

At the same time, the new cars had to keep an average speed on rough terrain of at least 40 km / h, which was unattainable for the classic 4310.

Development work received the code "Mustang". We began to develop hydromechanics together with US.

But with the collapse of the Soviet Union, the topic was closed.

Naberezhny Chelny did not forget about the modernization of the original 4310 machine.

In the late 1980s (in parallel with work on the Mustangs), they began to design the conditionally second generation of military off-road vehicles.

By the mid-1990s, a 240-horsepower KamAZ-43114 with a carrying capacity of 6 tons and a heavy 10-ton KamaAZ-43118 with a 260-horsepower 7403 diesel engine appeared in the Russian army. The latter model was fitted with (among other things) sections of the new PP-91 pontoon fleet. The truck's wheelbase was lengthened by 353 mm. The track was slightly expanded and a 10-speed gearbox was installed.

It turned out to be a kind of cabover giant, which partially occupied the niche of KrAZ trucks imported by that time. The truck tractor was also refined, which received the updated index 44118.

On the second generation series, the plant workers for the first time tried to establish a local cabin reservation.

By the way, due to the sealing of the equipment of the trucks, in Naberezhnye Chelny it was still possible to achieve the required ford depth of 1,75 meters.

The Mustang theme ran from 1989 to 1998. Such a long period was explained both by the difficult financial condition of the plant, and by the fire that occurred in the engine shop, the elimination of the consequences of which required $ 1990 million in the early 150s.

Serial "Mustangs" were a unified family of off-road trucks, which included 4350 (4x4), 5350 (6x6) and 6350 (8x8). The carrying capacity of KamAZ trucks was 4, 6 and 10 tons, respectively. Power ranged from 240 to 360 hp. from.

Thus, two branches of military off-road KamAZ vehicles appeared in the Russian army at once - the classic descendants of the 4310 model and the new ones from the Mustang family.

In further history, the range of machines only expanded. The factory workers offered the army armored versions. And even extreme 730-horsepower all-terrain vehicles.

The ending should ...

    He lived in LF for 16 years.
    My father built the plant and then worked at the Foundry.
    In the army he served at KamAZ, first as a kung, then in Chechnya as a nurse (also KamAZ).
    Never let you down.

    A small amendment: it was not just the engine shop that burned down, but the engine plant.

      And then, you think from the butt on fire? ))))
      I always said that engine building (designing new motors) was a taboo for the USSR / Russia. According to the West, we should not have been doing this - at most, licensed copying of antediluvian American engines (as for the Gas-53 American Motor 1936).
      And they did everything for this so that we would not be engaged in motor building.

    In Afghanistan, he drove on KamAZ nalivniks, they called them suicide bombers.
    Undermining a land mine for a carrier is a definite death. For the Ural smiled like a land mine under the front left wheel exploded and the dummy's right leg remained on the gas pedal. As a rule, the driver was injured in both legs with numerous fractures but survived.
    Kraz is another matter. Three meters of life, as they said. True clumsy and not dynamic. But in terms of survivability when undermined, the leader.

          Moreover, Ural and Kamaz are cars of the same weight niche .... Bridges, a diesel box, it is quite possible to have a common one. The only thing Kamaz is easier to scale 4x4, 6x6, 8x8, 10x10. And "nosed" ones longer than 6x6 cannot be made

            I agree. the same 131st zil could be produced in a 4x4 version. Wouldn't be a bad alternative to shishiga. and the logistics in terms of spare parts would have been better. But history does not know the subjunctive declension unfortunately

            Well, there was 4322, which had about 40% of the KAMAZ cab (from a solid roof, rear wall and windshield, everything else was either cut off or built up), its engine and gearbox. And before 4320 (and modification) with a diesel engine 740 (third set) and a box kamaz-141.
            Bridges in the Urals had their own, because no one in the USSR in the Urals after the launch of KAMAZ have not followed, and the bridge 375 is a non-coherent beam and main gear housing and pressed into its tubular axle housing. Therefore, to raise rn car 375/4320 it was risky, as it did with KAMAZ 43118.
            Nevertheless, the Urals - a thoroughbred army vehicle (BAT), KamAZ - AMS.

    In the Armed Forces, two families of trucks, duplicating each other, are developing in parallel.
    It is clear that the industry must be supported, but common sense must remain. They tried to sort out these two families at the tactical and operational level, but to no avail.
    By world standards of building the armed forces, such a situation is game.

      The Urals are generally 90% on defense orders. Only last year they made a new car with a new cab (tractor and dump truck) 6x4 and new diesels.
