With the new powertrain was possible the achievement of the main objectives: reducing the burden on millennia differentials, increasing braking efficiency and, most importantly, increased torque, or rather, the implementation of its wheels with the maximum value. This allowed the car to tow a trailer full weight up to 3.8 tons
Car suspension – fully independent, double (A-shaped) wishbone. Levers and many other parts of the front and rear suspensions are interchangeable. The design of the rear suspension repeats the front with the only difference that the springs made from the levers back.
Looking for independent suspension “Hummer”, doubt its durability and reliability arises: thick arms, powerful silent blocks, springs, more like a wagon than a car. Designers managed to increase the ground clearance to 400mm, removing the higher gears, almost hidden inside the body all the vital system up to the exhaust pipe, the last of which took place inside the left wheel arch.
Brakes – ventilated disc. Staging anti-lock braking system (ABS) was not provided. To reduce abrasion from road dirt and brake located near the differential housing.
Parking brake – disc transmission.
Bus. On the wheels of the machine are mounted, all-terrain flotation tires low pressure GoodYear (“Goodyear”) -other SUVs on these expensive tires did not even dream.
There is also a system built-in compressor with a centralized tire inflation. On the dashboard of the driver to enable the control system is a special toggle switch that is acting on the compressors to either the front wheels or the rear axle, can be lowered or swap wheels front only or rear only. The adjustment range is from 0.7 to 2.45 ATM. If the tire pressure falls below 0.55 ATM. panel lights red warning indicator.
The inside of the tires on the rims to put on special rubber bands that allow run-flat tyres, drive about 50 miles at speeds up to 50 km/h.
Headlights, sidelights and dimensions. Front light headlight, sidelights and direction indicators are housed in special cavities of the body. They do not advocate the envelope body and have a minimum possibility of damage. There is one feature: the direction indicators do not begin to operate until the position lamps are activated.
Devices, switches. At the top left on the instrument panel, is lever start, replacing the key; below is a combination of arms control lighting, dipped-main beam switch foot button.
The switch turns – primitive, resembling the levers of the 1950s To turn on the alarm this lever is necessary to stop to rotate clockwise.
Four arrow pointer on the panel inform the driver about the work of the major systems of the machine. One of them shows the oil temperature in the torque Converter that is very rare.
The steering column may move up and down, setting in a convenient for the driver position, depending on, for example, from its growth. The steering wheel has a thick plastic rim and well-kept hands.
On the floor under his feet were two pedals. The presence of automatic transmission made it unnecessary to clutch pedal.
Cabin. The interior of the car was very roomy, although the driver’s seat and the front passenger seat shares the wide engine cover, partially entering the salon. In the rear two seats are located on the sides, between them a narrow decoy bench.
The driver sits very close to the left side, almost resting his elbow on the door; on the right side it is limited by the hump cover. All instruments and controls are conveniently located from the driver at arm’s length.
The vertical windshield of the two identical sections are flat. If you suddenly break left, his place can be supplied with exactly the same shape of the right glass and then continue.
The housings are equipped with large side mirrors; rear view mirror, on the contrary, proved to be too small, as indeed the rear window of the cabin.
The handling and maneuverability of the vehicle. “Hammer”, according to experts, it is easy to manage. Handlebar -easy, no need to work the gear stick. Impressive dynamics of dispersal and braking for a car this weight. However, the car is too sensitive to side winds that lead him from the straight path.
Cross off-pavement, road, terrain -is beyond praise. The thrust of the engine and the degree of increase in the torque of the torque Converter is enough and at high gear. While moving from track to track, even slipping in the clay work well millenia lock all the wheels rotate simultaneously.
Clearance machine – high: up to 400 mm Gearbox with transfer box hidden in the tunnel, deep into the interior.
Steering, gearbox, fuel tank – all protected from hitting the ground. The body almost does not exceed the dimensions of the wheelbase. Its front overhang is completely absent, and the location of the rear beam allows the car to move down from the big ledge without risk to catch the stern, or, conversely, to move the vertical wall height of 0.6 meters.
The auxiliary gearbox, all gearboxes, starter and winch machine is made waterproof, whereby it is able to transcend the ponds to a depth of 0.76 m. in addition, the machine can simply be mounted a set of equipment that outputs air intake and exhaust pipe at roof level. In this embodiment, the fording depth increases to 1.52 meters.
Car preodolevat rise to 60% and is not afraid of the side slope of 40%, confidently passes in the snow glubinoi to 0.6 meters.
The additional armor. In armor protection “hammer” used composite materials using Kevlar. Armored models are equipped with bullet-proof windscreen and the same – on the door, the latter can be raised and lowered. Armor, however, protects only from small arms fire and shrapnel. For surer protection from enemy fire on cars hang an extra set of armor plates.
Machine-gun armored M1025:
1 – a cowl; 2 – the cover of the air intake of the engine; 3 radio AN/GRC-1660; 4 – laying the disassembled machine gun M60/7.62 mm; 5 – adjustable platform heavy (in the stowed position, the M60 machine attached thereto); 6 – individual devices of night vision (2); 7 – hand grenades; 8 – ammunition for the M60 machine gun; 9 – machine-gun night vision sight AN-TVS-5; 10 – transport position of the M60 machine gun (in disassembled state); And a nest on the antenna mount; 12 – rolled camouflage net; 13 – built truck mount machine gun M2; 14 – phone A-312/RT; 15 – can of water; 16 – individual night vision sight AN/PVS-4; 17 – fire extinguisher

Modification and modernization
Initially, the range HMMWV AM General was six basic models. Then the army’s “Humvee” was published in the 15th basic models: two General purpose, two – for transportation of bodies-containers, eight conveyors of light weapons and three as ambulances. The main differences are modifications to the level of reservation of the body (unarmored, with built-in armor, with reinforced armor) and the presence or absence of the winch.
The main military version of the model is М998 (Cargo/Troop Carier) is a Transporter of infantry and a truck. Its curb weight is 2360 kg, payload – 1250 – 1635 kg. When in 1991 the military was required to increase capacity, AM General has strengthened the frame, the support platforms of the springs, replaced the rear springs on bopee tough, reinforced shock absorbers. As a result of the increase in curb weight is 182 kg payload increased to two tons. In the beginning of 1994, passed the following upgrades (A1) consisting in the alteration of the interior of the power supply circuits, the change gear ratios of the transmission, install a new rear axle and move the wheels larger. The improvement in 1995 (A2) was more radical: the motor was replaced by a 6.5-liter diesel (170 L. E., 393 Nm), the transmission – Quad-band with electronic control, installed Central control system tire pressure.
Further development version of the A2 has led to the emergence of variant ECV (Expanded Capability Vehicle) capable of carrying a payload of 2406 kg. was modified differentials, brakes, axles, wheels and frame. To match the traction and dynamic requirements was installed a 6.5-liter turbodiesel engine (V8, 190 L. E., 522 Nm).
Production samples of the car can be installed the following weapons: anti-tank missile system BGM-71A TOW, 40-mm automatic grenade launcher Mk.19, 12.7-mm machine gun “Browning” М2НВ and 7.62-mm M60 machine gun. In the course of the fighting in the Arabian desert in 1991, was tested self-propelled anti-aircraft system “.”, equipped with missiles-FIM-92A “stinger”. Was also tested the car, armed with 25-mm automatic cannon.
In the armies around the world
Now the car “hammer” serving in the army and Marine corps of the United States, rescue and fire services, geological exploration, a variety of government agencies. These machines are used in the armies of many countries, and the Portuguese firm Uro and the Swiss MOWAG arranged a mass production of copies of the American SUV for the needs of the armed forces of their countries. The army issued Hummers in China.
The press reported the following volumes of “hammer” abroad: Albania (over 300 items); Algeria (more than 200 PCs.); Afghanistan (over 2700 items); Bulgaria (50); Georgia (12 PCs); Greece (500 PCs + edition under license in Greece); Denmark (30 PCs.); Egypt (more than 3890 units); Israel (over 2000 items); Iraq (over 3960 PCs); Iran (10-20 pieces, transferred to France); Colombia (more than 400 PCs.); Lebanon (285 -300 PCs.); Macedonia (56 PCs.); Morocco (650 pieces); Mexico (more than 3638 PCs); Philippines (300 pieces); Croatia (12 PCs); Chile (200 PCs.); Ecuador (about 30 pieces). There is no exact quantitative data, but machines of this type are also used by the troops of Argentina, Bosnia and Herzegovina, Dominican Republic, Yemen, Estonia, Latvia, Lithuania, Luxembourg and Panama.

Many countries are seeking to purchase Hummers М1165 third generation produced since 2006 They were bought by Spain (over 150 pieces); Poland (217 PCs); Slovenia (30 PCs.); Romania (8, plans for 50 – 100 pieces); Ukraine (10 PCs obtained from the United States in peacekeeping missions). The third generation of machines used in the armies of Venezuela, Zimbabwe, Portugal, Saudi Arabia, Serbia, Slovakia, Taiwan, Turkey and Thailand.
In October 2009, media reported that the Ministry of defence of the Russian Federation considered the possibility of acquiring 3,000 units of HMMWV. The price asked for 190 thousand dollars. (obviously, this pre-owned).
Problems army “Hummer”
For a long time, the military Hummer is positioned as the best, fastest and invincible army vehicle. And only at the end of the service the Americans were forced to recognize – these machines are powerless against the old Soviet weapons and improvised guerrilla min.
The war in Iraq for the United States was both a testing ground for military equipment. Starting operation in Iraq, the Americans did not know what they will have to face after the victory. Today coalition service members have to deal not with soldiers and armored vehicles obsolete army of Saddam, but with the guerrillas, armed with grenade launchers and mines.
A chance to escape during a mine explosion and when getting into the car a cumulative shot from an RPG can be, reseeding of the internal compartments of the conveyor of “armor”. When you hit the cumulative ammunition produces a powerful stream of red-hot gas-metal mixture, which burns through steel, creating a positive pressure inside that carries the death crew.
Even worse is the case with protection against mines: even with the latest, armored vehicle М1114 “holds” the explosion of a five-kilogram mine – if it explodes under the front wheels, and just three pounds – if it goes off underneath in the back. The armor can withstand the blast from a 155-millimeter shell exploded a few meters from the car, or the fire from the machine gun bullets of 7.62 mm.
Machine guns and rocket-propelled grenades from Iraqi guerrillas abound, because the most terrible for the American soldiers job remains on patrol outside of a military base “hammer”.
With the explosion of a powerful bomb, those who are “on Board”, often receive severe concussion, and often die. The crew has even worse – from the explosive device only protects the relatively thin armored bottom.
It turns out that the most vulnerable machine in Iraq is an SUV HMMWV. In 2003 operation against the government of Saddam Hussein participated 10 thousand cars. In the future, this number had doubled. And most of the vehicles had no armor. According to American newspaper the New York Times, this machine is designed in the midst of the cold war, not only does not meet modern requirements – it originally did not meet the conditions of any theatre of hostilities.
The box-shaped body and a complete lack of armor, make “Hummer” steel coffin on wheels – the view from the narrow Windows are bad, but the machine itself – the goal is large and vulnerable.
In the framework of the program to better protect the “hammer” came М1114, but it did not solve the problem.
Information falling into the press, shows that Americans in Iraq are fleeing from the cumulative ammunition, removing the doors from their cars. However, inside the soldiers are still open for the gunners.
“Hummer” no doors have another advantage – open off-road vehicle allows you to better see what is happening around and to fire from small arms. The Americans spent a lot of money, created antisnaypersky version of the car, on the monitor in the cab which in the case of the shot shows the location of the shooter, but you don’t hear these very expensive cars were massively entered the army, and from mines microphones do not protect.

As one American soldier who is serving in Iraq, “every time we leave the gate of the base, we are praying.”
So, what is the result? On the one hand, the “hammer” was a revolutionary step in changing the car fleet of the us army. Outside of the fighting machine is really good. On the other hand, create light universal car-armored vehicles, the Americans also failed.
Harsh experience is that on the roads of recent military conflicts the army almost all over the world move mainly in four vehicles – a Hummer, Mercedes G-class, Land Rover Defender and our UAZ.
