Ural-6370: technical characteristics

Oil worker, gas worker and soldier of the 21st century

Cabover layout, 6x6 off-road all-wheel drive, up to 412 horsepower, up to 20 tons of load capacity, 600 thousand kilometers of service life - all this is about the promising Ural-6370 family of heavy-duty vehicles.
Trucks of this brand are produced in various versions: truck tractor, pipe hauler, dump truck and universal chassis, with a standard or extended wheelbase. For the first time, the new cabover Ural of this family, in the “dump truck” version Ural-6370-1121, was presented to the general public at the 11th International Specialized Exhibition “Construction Equipment and Technologies”, held in June 2010 in Moscow. This demonstration was followed by detailed reviews of the new product - in the most authoritative domestic auto magazine "Behind the Wheel" (in September 2010) and in other automotive publications. At the end of 2010, serial production of vehicles of the Ural-6370 family began at the Miass plant.

Currently, this family is represented in the production program of the Ural enterprise in the following versions: “dump truck”, “trailer tractor”, “universal chassis for special equipment” (in particular, a fuel tanker tanker, a combined road vehicle, a fire truck, a crew bus).

UralAZ specialists also succeeded in their desire to supplant KamAZ in supplying the Russian Army with trucks. After several years of demonstrations and serious testing, the Ural-6370 was included by the Ministry of Defense in the list of vehicles to supply our Armed Forces. And in 2015, an armored car based on it was presented - Ural-63704-0010 "Tornado-U", which a year later was also accepted for supply to the Republic of Armenia.

Tornado in Kubinka: getting acquainted with the 16-ton Ural Tornado-U truck

What happened at the Army 2015 forum in Kubinka near Moscow can be compared to a tornado: there was no end to those who wanted to “look at the tanks”! There we met the previously unseen 16-ton Ural Tornado-U truck.

The last issue of the column talked about the debut of Ural Next trucks at the STT-2015 construction exhibition. And at Army 2015, the Ural Next was shown in an army version (it bears the name Ural-M, after the name of the chassis). Let's reveal the secret: this car was converted from a civilian tank that was parked on the STT! Instead of a “barrel,” a flatbed body with an awning was installed, the cabin was repainted from silver to khaki, and the fuel tanks were covered with sheets of metal, apparently simulating armor.

The front panel is unified with the armored Typhoon-U and Ural-VV

It is already known that such a Ural-M, or, as they say in auto, will become the basis for a whole family of Motovoz-M army trucks - with wheel formulas 4x4, 6x6 (both models with Next cab) and 8x8 (with cabover cab). The “motor locomotives” will also be armored: such vehicles will bear the general name Ratnik. But the carrying capacity of the Ural Next... That is, the Ural-M is no more than 12.5 tons, which limits both the payload and the weight of the armored shell.

If you look at the corner of the cabin, you can see that it is assembled from panels

Tornado-U even has air conditioning

0 / 0

What if you need an even heavier truck? This is Ural Tornado-U! Pay attention to its cabin: it is frame-panel, much like the prototype (of course, with a different design) shown in 2006. Some of the external panels - doors, hood, roof - are made of composites, while the installation of KDZ is also provided - a complex of additional protection from armored panels.

The entrance is high, but there is also a suspended step and a handle in the doorway

There are three seats in the cabin, and the driver's seat is sprung, Grammer

The creators call the new product a replacement for KrAZ, since its characteristics are comparable to Kremenchug all-terrain vehicles: payload capacity - 16 tons, total weight - all 30 tons. But the engine power is much higher, 440 hp. And what kind of chassis is this? After all, the Urals themselves do not produce such heavy-duty bridges! It turns out that the car is built on the basis of the civilian cabover Ural-6370: the axles are Hungarian Raba, the engine is YaMZ-652 (licensed Renault dCi 11 with common rail injection), the clutch is Sachs, the gearbox and transfer case are ZF. Just how justified is the use of European brands of units on Russian defense equipment?

Under the hood of Tornado-U is YaMZ-652...

... aka licensed Renault dCi 11

There are hieroglyphs on the filters: some of the motor components come from China

The Tornado-U exhaust pipe almost touches the front suspension: wow!

0 / 0

However, it is already known that this year a model with “non-NATO” units will be tested, and in the future it is promised that both models - Ural-M and Tornado-U - will have exclusively Russian components (apparently, including localized ones). Moreover, Tornado-U will be produced in fully armored versions 6x6 and 8x8 (Tornado-U-T), and, apparently, such vehicles will become analogues of today's Ural Typhoons, only less complex and expensive. After all, Typhoons have independent suspension, an automatic transmission, a lot of electronics... But here we have a traditional chassis and a manual transmission.

This truck was recently a civilian Ural Next with a tank. And now it has turned into an army Ural-M

The plans are as follows: this year - “initiative development of the chassis, components and assemblies”, “making a decision with the Customer on Typhoon-U-T” (which kind of Customer is easy to guess), in 2016 - the start of R&D (development work) , and from 2022 - serial production. And rightly so: conventional army Urals, for all their advantages, are already quite outdated. Moreover, at the exhibition, drops of oil could be seen under one or another military Ural-4320... This is something new models definitely shouldn’t have!

Hello, old “laptezhnik”: a “single-bucket military excavator” based on the KrAZ-255B (with a wood-metal cabin!) was put into service back in 1977 and is still in service

UAZ Patriot for the Ministry of Defense: cast wheels - only for effect, but the package includes special electrical equipment, reinforced suspension and weapon mounts

The usual BTR-80 debuted at the Uralvagonzavod stand, but with a modernization complex: grilles protecting against grenade launchers, an “unmanned” turret, anti-fragmentation protection, new communication and navigation systems, video surveillance and air conditioning

The PTS-4 floating conveyor is made on units of the T-80U and T-90 tanks: load capacity - 12 tons on land and 18 tons on water, maximum speed on land - 60 km/h, on water - 15 km/h (8 knots)

Now the Kalashnikov Concern will also be involved in boats: they are made by the Rybinsk shipyard. The airborne BK-16 shown is equipped with four 7.62 mm machine guns and a heavy machine gun (12.7 mm). Speed ​​- up to 40 knots

Benches in the shape of sea mines, pots with plants in the shape of exploding missiles... A wild fantasy, however

For a stylish leather jacket with fur with the “Russian Army” emblem, the Ministry of Defense is asking almost 83 thousand rubles. Pure nonsense!

What did singing bowls, harmonizing space, and the “Hunan Tea Producers Cooperative Society” do at the exhibition? Apparently they helped increase defense capability!

Cabover dump truck Ural 6370

The automobile plant built in Miass was originally intended to produce military equipment. The special equipment produced was distinguished by its increased cross-country ability and was not difficult to operate. After the collapse of the union and the decline of the defense industry, the plant developed and produced cars that became in demand in the market of various industrial sectors. As a result of design activities, a new heavy-duty vehicle appeared, which is in great demand. It has proven itself well in various difficult conditions. Conveyor assembly of equipment began in 2010. Today, the model is produced in several versions, one of which is a dump truck with rear unloading.

Transmission and axles Ural-6370

The transmission is assembled from European-made components. Clutch – “Sachs MFZ-430”: friction, dry, single-disc, with a diaphragm spring, hydraulic drive with pneumatic assistance.

The gearbox is one of the best currently available for heavy trucks of this class. The ZF-16S2220TD models have a manual 16-speed gearbox, with synchronizers in all gears, providing an exceptionally high level of vehicle controllability throughout the entire speed range. The Ural-6370 truck is also equipped with a ZF-VG2000 transfer case. The transfer case is mechanical, two-stage, with a cylindrical lockable center differential.

The working brake system of the truck is with a three-circuit pneumatic brake drive, an automatic locking system and an air preparation unit. The emergency braking system is one of the circuits of the working system. Parking operating system - with four spring energy accumulators acting on the brake pads of the wheels of the rear and middle axles. Auxiliary brake system: A compression brake is installed in the exhaust system.

Truck cab Ural-6370

The Ural-6370 is equipped with a two-seat cabover cab, tilted forward, equipped with a full-fledged berth. Compared to classic Urals, in this cabin the level of comfort, interior decoration and workplace parameters (visibility and sound insulation) have been raised to unprecedented heights. The tilting of the cabin in order to get to the engine is hydraulic, with the possibility of duplicating the hydraulic drive with an electric drive.

This cabin is not original: the UralAZ designers used a proven, high-quality, excellent truck cabin. The spring suspension with hydraulic shock absorbers provides the driver with a decent level of comfort. The air-suspended driver's seat is equipped with a modern "Pilot" seat.

The steering column in the Ural-6370 cabin is adjustable in tilt and height. The steering is equipped with a hydraulic booster. Electrical control of the side rear-view mirrors greatly facilitates their adjustment; for mirrors, as an additional option, electric heating is also provided. The upholstery of the engine compartment is made of material that is practical for immediate use.

Reviews about Ural-6370

There are still very few reviews about the new hoodless Urals: mass production started only a few years ago, few vehicles have been produced yet, and experience in their operation has not yet been accumulated. According to the drivers’ first impressions, the new “Ivekov” cabin is, of course, very good, but the rear window in it is “useless.” It only reduces the level of thermal insulation of the cabin, and just where the berth is located. Which, in the conditions of the Far North or Siberia, is far from the least important factor.

The dump truck designers provided for the installation of an electric drive for the convenience of tilting the cab; it was available on experimental and demonstration vehicles. But production machines on sale are equipped only with a hydraulic drive.

The quality of assembly of Ural-6370 trucks at UralAZ raises complaints. Some cars have leaking axles (especially the middle one), the rear engine mount breaks, there was a case of steering rods breaking while driving: the ends flew out of the crossbar (had to be welded). There are no complaints about the power reserve and cross-country ability of the Ural-6370.
