The last century was in many ways not the best time in human history. There were wars, and the newest deadly diseases, there was a division of countries and the drawing of borders … But a lot of good things happened at that time. Most scientific discoveries and most useful inventions can easily be attributed to the latter.

In addition, the flourishing of technology, which occurred during the transition to a post-industrial society, also touched the automotive industry, and in all countries. For Russia, and at that time still for the Soviet Union, it was a good time in this historical aspect. A striking example of this is the KrAZ-255B car.

What will we talk about?

The topic of conversation, as you already understood from a short preface, will be this particular car.

This all-terrain vehicle is a truly iconic thing, one might say, a milestone for the entire automotive industry of the last century.

As a matter of fact, the KrAZ car - "lappetzhnik", as it is also called by drivers, was one of the most massive trucks in such a vast country,like the USSR at the end of the twentieth century. If there were flaws in it, they were constantly corrected by engineers. In fact, this version of the all-terrain vehicle appeared. Previously, other models were produced, but over time, everything turned into exactly those cars that can still be found on the road today, although they are no longer produced in the twenty-first century.

Legacy

For its time, the 214th model was quite good - it coped with its duties, and this turned out to be quite enough. Nevertheless, by the sixties, time nevertheless caught up with this, no doubt, a great car. The need for modernization no longer just loomed in the distance, but literally hung in the air.

These KrAZ trucks did not differ much from each other. To be honest, it was only possible to distinguish one model from another by wide-profile tires. Nevertheless, there were modifications, and they seriously changed the design of the car.

Internal content has been changed by an order of magnitude, unlike the previous version. So, the KrAZ-255B car became the cargo "king of the roads". All the drivers recognized this, even though they called him in daily conversations nothing more than a "lappeteer". Nevertheless, even forty-year-old models are still used throughout the CIS, and in other countries too. This only speaks of the high quality of production.

Main parameters

Kremenchug Automobile Plant produced a lot of such cars. All of them were made on the basis of the 214th model and for seventeen years they were leading in many industries.

Talk about equipment should start with a diesel engine. The design that was used here is called YaMZ-238. It is quite powerful, but at the same time economical unit.

Wide-profile tires, which have already been discussed earlier, have generally become a distinctive feature of the KrAZ-255B car.

It was intended mainly for the transport of various goods.

In addition, the ease of riding on rough terrain only added to the possibilities. The latter were used by many state institutions, ordering certain modifications, specially sharpened for a single purpose.

The cabin, which the model was equipped with, was made on the basis of a wooden frame sheathed with sheet metal. The glasses used were strong enough to withstand high pressure. Three people were freely accommodated inside.

KrAZ-255B - engine specifications

KrAZ can be described for quite a long time. You need to start with exactly the design detail that sets this colossus in motion.

Of course, this is the engine. But not only what, but V-shaped, with eight cylinders. Everything was powered by diesel, and fuel consumption, especially considering the size of the car, was quite low. Each of the installed cylinders was equipped with two valves, which increased the overall power.

The latter was an impressive figure of two hundred and ten horsepower at 2100 rpm. The torque is also quite impressive - 90 kgf / m, taking into account one and a halfthousand revolutions per minute. The compression ratio here is sixteen and a half, and the displacement is almost fifteen liters.

Pendant

No less important part of the car than the engine. KrAZ-255B was equipped with both front and rear suspensions.

They were made a little differently, which is pretty logical given the weight and dimensions they had to work with.

The front suspension was carried out using two longitudinal semi-elliptical springs. The latter were equipped with an additional pair of double-acting shock absorbers. That is, they were both hydraulic and telescopic at once.

The rear suspension, in turn, was based on the same springs as the front. However, there is a difference, and it lies in the whole six jet rods.

Clutch and gearbox

Kremenchug Automobile Plant used a clutch of the same class as the engine, that is, YaMZ-238. The design was based on two dry discs with multiple coiled compression springs.

The gearbox is called YaMZ-236N, according to its characteristics it was designated as a five-speed and three-way. The system of constant gearing worked here, of course, without taking into account the first and reverse gears. It is also worth noting separately the presence of synchronizers on the transitions from the second to the third and from the fourth to the fifth speed.

Driveline and transfer case

The first was designed from a whole five cardan shafts. The mechanism was strengthened by an intermediate support. Thus, the whole structure was strong enough and at the same time easy to assemble. Only open type shafts were used in production.

The second, in turn, was characterized as mechanical and two-stage.

Also note the presence of a center differential for the rear bogie. With the help of this device, the power take-off for the rear winch and other attachments was turned on.

Bridges

Three of them were used in the design. Naturally, they were unified according to the main details. Each of the trinity was equipped with its own gearbox. The axle shafts were completely unloaded.

Of all the bridges, the front one stands out. It is equipped with an additional mechanism. The latter is a hinge of equal angular velocities. Motorists know that they transfer torque to the drive wheels for increased agility during cornering.

Some changes have also been made to the design of the middle bridge. So, there is a processed area here. It is used as a support to properly install the rear axle driveshaft.

Optional equipment

In addition to all of the above, it is necessary to note some more spare parts. KrAZ-255B simply cannot exist without them.

First of all, this concerns the engine preheater, as well as the centralized tire pressure control system. For certain modifications of this all-terrain truck, another thing was also characteristic.attachments, but this is not so significant.

It is also necessary to especially note the tires, which have been discussed more than once before. Their dimensions are very impressive - 1300x530x533 mm. Given that the design involves the use of six wheels at once, this is quite an important point.

One more thing to say about batteries. There are two of them used here at once, which is logical, given the size of the machine. The series of these devices is indicated by the marking 6ST-182EM.

Dimensions of KrAZ-255B

Separately, it is worth discussing the dimensions of this huge car. Actually, it is a rather impressive design, which should be taken into account both when driving and when buying.

The length is a little over eight and a half meters. More specifically, 8 meters and 64.5 centimeters. The width of the car is quite large - two meters and three quarters. Height, by the way, is a rather special measurement for a truck, since there are two different states - the dimensions of the cab or the general one, along with the awning. Here the first indicator will be two meters and ninety-four centimeters, and the second, respectively, three meters fifteen centimeters.

Given the rather strict rules of the road regarding trucks, those who are going to purchase KrAZ should think twice and carefully read the documentation. Some roads will become inaccessible, which creates unnecessary difficulties.

Known modifications

This was discussed a little earlier. Many authorities ordered specialized cars for themselvesfor your own needs. Although the 255B is the most widely known, it is far from the only one that can be found on the road even today.

First of all, I must say about the basic improvement of the car. It was marked 255B1.

Actually, the whole change was in the braking system. The brake drive was made separate, which seemed to the plant engineers a good idea. So it really was. After 1979, the Kremenchug plant produced exactly them.

KrAZ model number 255B is also quite well-known - it is a truck tractor. It was intended, as you might guess, to transport large loads in a trailer. The weight of the latter could reach twenty-six tons, but sometimes even exceeded this already impressive figure.

KrAZ-255D was not put into mass production. This is also a truck tractor, only for working with a specific trailer. The prototypes passed the tests, but the performance did not reach the desired level.

At one time, KrAZ-255L trucks, that is, timber trucks, were quite popular.

They differed from others in the absence of a system for adjusting tire pressure, but they were adapted to work with various trailers by dissolutions.

Besides, there is another modification of the piece, one might say, production. 256B1-030, only eighteen pieces were produced, and they were intended to work in the radiation contamination zone around the Chernobyl nuclear power plant. For the manufacture used specificmaterials such as lead and crystal. After the end of the service, they were buried in radiation burial grounds.

Conclusion

A few parting words for those who are going to buy such cars.

Firstly, the repair of KrAZ can be a real test for you. The fact is that there are not so many new mechanisms in working order. Therefore, finding something will be quite expensive. In addition, using substitutes is not very safe, since they are sharpened for other mechanisms. The machine itself was discontinued over 10 years ago.

Cost

What is the price of the domestic car KrAZ-255B? This question is very difficult. Serial production was completed a long time ago, which means that if you buy, then only a used car. And here everything will depend on the state. On average, the purchase will cost you five to eight thousand dollars.

So, we found out what the domestic KrAZ car has technical characteristics, dimensions and price.
