Technical characteristics and engines
The heart of most Ural heavy trucks are diesel engines produced by Yaroslavl Motor Plant (YaMZ). The most commonly used units are the YaMZ-536 and YaMZ-650 family, which comply with Euro-4 and Euro-5 environmental standards. These power plants known for their high torque at low revs.
The car's transmission also deserves special mention. Many models have manual transmissions YaMZ-239 or automated versions that optimize fuel consumption. An important element is the transfer case with locked center differentials, which ensures uniform distribution of traction.
Below is a table of the main technical characteristics of popular modifications:
| Model | Wheel formula | Engine | Power (hp) | Load capacity (kg) |
|---|---|---|---|---|
| Ural-4320-1912-60 | 6x6 | YaMZ-6565 | 312 | 12000 |
| Ural-5557-1151-72 | 6x6 | YaMZ-5367 | 310 | 13500 |
| Ural-6370-1151-73 | 8x4 | YaMZ-6585 | 420 | 24000 |
| Ural-44202-1912-60 | 6x6 | YaMZ-6565 | 312 | Truck tractor |
It is worth noting that for arctic versions special preheaters and insulated cabins. This allows you to start the engine at temperatures down to minus 60 degrees Celsius, which is a unique indicator for equipment of this class.
Cross-country ability and off-road qualities
The main trump card of the Miass plant's products has always been cross-country ability. System central tire inflation (CTIS) allows the driver to change tire pressure directly from the cab, adapting to the type of ground. On soft sand or snow, reducing pressure increases the contact patch, preventing the machine from digging.
Ground clearance and suspension geometry are designed to minimize the risk of getting stuck. Differential lock It is activated by electro-pneumatics, which simplifies control in difficult conditions. The vehicle can ford a depth of up to 1.75 meters thanks to special preparation of the exhaust system and breathers.
⚠️ Attention: Operating the tire inflation system on hard surfaces at high speed can lead to overheating and damage to the tires, use the “highway” mode in a timely manner.
Testing of equipment is carried out at special testing grounds that simulate the conditions of the Far North and high mountains. Engineers are constantly improving leaf spring suspension and shock absorbers to ensure not only cross-country ability, but also an acceptable level of comfort for the crew when driving over rough terrain.
Secrets of military modification
Military versions of the Urals are often equipped with additional armored elements and mine protection systems, and also have enhanced electrical shielding for operation in electronic warfare conditions.
