The design of the tractor is quite simple, which meansreliable. Cabin MAZ 537, photo of which was initially unavailable due to military secrecy, four-seater, two-door, metal, equipped with a self-contained heater. The engine is located behind the cab in the engine-transmission compartment, then there is a transfer case transmitting the rotation to eight independent axes. At the rear of the load platform is a fifth wheel coupling. Some modifications of the machine are equipped with a winch. The tractor moves on eight wheels, the four forward ones are turning. Tubeless tires are equipped with pumping, in the event of a puncture, a pressure loss compensation mechanism is activated. The MAZ 537 Hurricane, whose technical characteristics speak of power and reliability, is a good example of the achievements of military equipment.

The project to create a new powerful tractor

In the early 50-ies of the 20 century in the USSR arosethe need for new powerful military vehicles. Rocket complexes, heavy armored vehicles on caterpillar tracks, fortification excavators and other equipment needed transportation both for near and long distances. Especially difficult was the redeployment of military units, which was carried out regularly. Up to six months it took to travel by rail and small-sized motor transport.

The design of the universal tractor startedIn the autumn of 1954, and by the summer of 1956 prototypes were ready. The four-axle full-length four-wheel drive chassis has become the base for several modifications of the military saddle tow. Characteristics of the machine were designed for long-distance travel at a speed of 40 - 50 km / h. The capacity of the tractor was sufficient to transport the platform with a ballistic intercontinental missile. However, the road train could only follow the road with a hard surface and only on level ground. To overcome even a small recovery did not work, because the trailer did not possess inertia.


Tractor MAZ 537 "Hurricane", technicalthe characteristics of which showed its reliability, was also widely used in regular troops for the transportation of various long-range combat systems. However, the towing of long platforms was hampered by the overly remote coupling. The road train did not fit into the turns, maneuverability was limited.

Every move to another locationIt was an archetypal task for the military, the road train had to be stopped often, by means of complex manipulations, to align the course. Difficulties arose because of the narrow roadway. In the post-war USSR, all roads were extremely narrow, motor vehicles moved in a single row, in both directions. The danger of moving into the ditch was every minute. The heavy tractor occupied its full lane and then drove to the other. Complaints were filed from the civilian population, but the situation did not change.

In the end, the military departments becamewarn of the upcoming transportation of missile systems in advance. The notices of the forthcoming redeployment were received by road services and the state traffic inspectorate. The police blocked traffic on the highway, within 25-30 kilometers, the tractor with the trailer occupied the entire width of the carriageway and safely passed the free site to the next post. Then the next run was blocked.

Two years later, the design bureau of MinskAutomobile plant has started to develop a saddle version of a prime mover with the MAZ 535V index. The body was abolished, in its place was installed a coupling device with an automatic locking lock and two degrees of radial rotation. Vertical load on the rear part of the tractor thus increased sharply, the designers had to reconsider the parameters of the rear suspension. They stopped on bridges with a planetary gear and a differential. Thus, the rear axles assumed the main load.

The last version of the tractor was differentmore perfect engine power and cooling system. The flanges of the cardan shafts of the transfer case were strengthened. The need for this was dictated by frequent breakdowns when the loaded tractor could not overcome the rainy portion of the road and the engine torque tore the cardan joints.

The creation of a family of heavy tank tractors brandMAZ 537, the characteristics of which repeated the main parameters of MAZ 535 and MAZ 536 models, was the beginning of the era of new class of road-trains, with a high load-carrying capacity. There was a powerful incentive for the development of increasingly sophisticated heavy semitrailers and trailers for the transportation of multi-ton, indivisible cargo.

The need to move massive structureshas always existed. Abroad, road trains appeared much earlier than in the USSR, and this circumstance accelerated the development of Soviet vehicles of increased payload, as no one wanted to lag behind advanced technologies. To start, the design bureaus of the automotive industry developed the ZiS-10 tractor with a fifth wheel coupling on the basis of the famous ZIS-5 dump truck. The carrying capacity of the new car was only 6 tons. A small number of towers was produced, ZiS-10 did not receive wide distribution.

Foreign analogues

In the late 30-ies of the last centurymotorists got acquainted with two heavy road-trains of foreign manufacture, truck tractors Daimond T-980 and REO 28XS, transferred to the USSR in lend-lease. Overseas tugs worked in tandem with the three-axle semi-trailers Roden Trailer, the carrying capacity of which was 45 tons. The cars were equipped with winches and transported armored vehicles.

At that time in the Soviet Union tanks and othersHeavy military vehicles moved exclusively on their own or were transported on railway platforms. Both methods seemed irrational, but there was no alternative then.

The post-war period

After the end of World War II in the USSRseriously took up the development of domestic heavy tractors for the army and the developing national economy. In 1951 the car factory in Yaroslavl mastered the production of three-axle vehicles YaAZ-210G with a platform and a powerful winch. A large-scale production of these machines could not be established, and in addition tractors could not pass off-road, especially during the rainy season or spring mudslide.

Thus, the tasks of creating heavythe vehicles still demanded a solution, especially as the country was undergoing rapid industrial construction, and the military department was developing strategic missile systems that needed mobility. The armored forces also needed reliable heavy-duty tractors.

Design department

The Council of Ministers of the USSR in June 1954decree on the creation of the SDB (special design bureaus) for the development of particularly powerful military tractors with the possibility of subsequent modification in the civilian industrial version. It immediately became clear that the existing plant technologies and equipment in the automotive production would not be enough.

I had to start from the machine shop, to buyabroad modern equipment and create new technologies. At the Minsk Automobile Plant a large MAZ MAZ was organized, under the direction of the chief designer Boris L. Shaposhnik. Before the specialists set a task to design and launch a heavy wheel tractor. This is how the MAZ 535 towing device appeared, which will soon turn into MAZ 537, a model with several modifications.

car of cars 537


Initially, the funds included in the developmentsupercar, were inadequate, since such a car can not be cheap. After adjusting the financial security of the project, the work began to boil. Non-standard solutions were adopted, which had never been used in the domestic automotive industry before. We had to take into account the special operating conditions of heavy-duty tractors, the adaptation of units to the temperature range from plus 50 to minus 50 degrees, profile cross-country and many other parameters.

Heavy truck tractor MAZ 537 started to produceserially in 1965. The car was intended for towing trailers and semi-trailers weighing up to 40 tons. From the basic version of the 537 model was different rear-biased (at 345 mm) fifth-linkage mechanism and reinforced rear suspension. The car MAZ 537 was in a mode of constant restyling. In the production process, the functions of the transfer box have been expanded, the rotation transmission to the generator drive has been established. The car's carrying capacity has significantly increased and amounted to 68 tons.

In parallel with heavy-duty truck tractorswere designed and produced by limited series of tractors for the transport of goods, up to 22 tons, along the highway. The body of such a car was not equipped with seats, had no arches and awning, was used exclusively for the carriage of goods. Under the body was a winch for self-hauling, in case the tractor would get stuck.

Maz 537 model


After some time the military MAZ 537modernized, and the car was assigned the index "P". Technical characteristics remained unchanged, but the winch was abolished, and the body was re-equipped to transport personnel. Along the folding sides, longitudinal benches and arcs for the awning were installed, which were adjusted in height - in the lower position the canopy covered the cargo, in the upper position it served as a protection against rain and snow for people. In accordance with its direct purpose, MAZ 537P tractor could tow platforms with missile systems.

The use of wheeled tractors requiredspecialists in maintenance, qualified drivers and corresponding material resources. Therefore, in the 1970s, specialized enterprises for the centralized transportation of large-size and extra-heavy cargoes were formed. Association "Spetstyazhavtotrans" was engaged in transportation of non-standard cargoes, developing thus optimum routes. With the help of MAZ 537 tractors, a marble boulder, weighing 300 tons, was transported to build a monument to V.I. Lenin in Leningrad. This unique transport operation was followed by the whole country.

Tractors MAZ 537 in the north were widely used,where laying of oil and gas pipelines was conducted. The unpretentious machine has proved itself well in a cold climate. Especially for the transportation of long-length gas-conducting joints, a pipe chute PV-481 was built on the basis of the MAZ 537 towing vehicle. Also, for working in the northern conditions, prototypes of fire engines, technical mobile stations, all-terrain vehicles of emergency medical aid were created. However, trial copies did not arrive in mass production.

In 1991 at the Kurgan plant of wheeled tractorsThe serial production of heavy semi-trailer KZKT-9101, with the carrying capacity of 54 tons, for the MAZ 537 towing vehicle, the technical characteristics of which fully coincided with the data of the semitrailer, began. The combination of components turned out to be successful, the buyers were able to purchase a tractor and a semitrailer within one order.

537 technical specifications

For many years of production, the MAZ 537,photos of which are presented on the page, are gradually obsolete, both morally and technically. The machine has exhausted itself, the potential for further development has dried up. Became apparent hidden shortcomings, a lot of criticism caused low power resources of the power plant. The operation of the tractor was connected with frequent breaks for repairs, the army MAZ 537 did not accommodate the crew, which was forced to follow separately, while transporting tanks and other armored vehicles. To do this, we had to attract additional cars.

In the end, based on the 537th model was createda new tractor KZKT-7428, which fully met the tasks of transporting combat caterpillar vehicles. At present, the family of powerful wheeled tractors successfully solves all the tasks of transporting heavy military equipment, as well as civil large-scale industrial structures.
