MAZ-6440: specifications and reviews

Minsk Automobile Plant, MAZ, specializes in the production of large-capacity trucks and dump trucks. In 2010, the design office of the enterprise began to develop a new truck saddle tractor . The model differed from its predecessors with the engine compartment of the hood type, a modern design and a luxury cabin.

New Trucker

The new MAZ, the characteristics of which were kept at a sufficiently high level, was intended for long-distance flights, long-distance and international, for the most complex routes of road transport logistics. The machine has all the necessary data to successfully complete the tasks. It's power and modern design, comfort and security. The car is rightfully considered a worthy successor to the traditions of the Belarusian machine-building industry.

Hood tractor and its advantages

European safety requirements for the operation of technical equipment have recently become noticeably tougher, especially with regard to the safety of drivers' lives. The engine compartment of the hood type has the property of energy absorption in a head-on collision. The front bumper, a powerful radiator grille with a cladding panel, a tail trim and a heavy engine take over the entire impact force. The inertia of destruction, thus, ends in the area of connection of the engine compartment with the cabin, and the driver, as well as the passengers, remains unscathed.

Another reason why hooded tractors are preferable to other MAZ trucks is the increased comfort level of the cab. Its location behind the front axle makes it possible to create a space in which the driver's seat and seats for two passengers are conveniently located, and behind them there is a two-berth rest area. In long-haul flights without such an arrangement can not do, because the movement takes place around the clock and replacement drivers need a full rest.

The next advantage is almost unlimited access to the engine and other components and units that are under the hood. The undeniable advantage of the new tractor MAZ-6440 was recognized as high repair reach of the engine and other units located in the engine compartment. To access the power plant, it is no longer necessary to lift a heavy cabin, as is done in most MAZs. Current regulations, minor repairs and preventive maintenance with a tightening of fastenings - all this became possible in road conditions or in parking. It is enough to open the hood of the car - and the driver with the mechanic gets full access to the power plant.

Presentation

MAZ-6440 is the first hooded tractor of Belarusian manufacture, except for the MAZ-205, produced in the post-war years, which had a very primitive design, unreliable, with poor technical characteristics. The modern hooded tractor is the most powerful machine with a whole set of advantages that are constantly being improved.

The Minsk Automobile Plant presented the novelty in 2011 at the International TIR 2011 Truck Show. The super-modern model produced a furore.

Restyling

A year after the first presentation of the MAZ-6440 tractor, buyers were introduced to the updated version, which has a more stylish exterior and an increased level of comfort. The wheelbase of the car extended by one meter, due to this it became possible to expand the cabin in the longitudinal plane and equip a rather spacious bedroom. At the same time, the front end of the car was modernized, the bumper of a complex configuration was installed, which did not have the shock-resistant characteristics, but was an example of aesthetics in terms of design, carried the headlights and was part of the stylish MAZ-6440 facings. The shape of the optics and grille was also radically changed . Another advantage of the tractor was also the developed passive safety of the car, which, according to these indicators, came close to the standards of the European Union.

Power point

The MAZ-6440 truck tractor is equipped with an eight-cylinder YaMZ D-283 engine with a V-shaped cylinder arrangement, with a working volume of 18 liters and a capacity of 600 liters. With., Standardized to standards Euro-4.

The diesel is combined with an automatic six- speed transmission of the brand "Ellison" 4500R American production.

The leadership of the Minsk Automobile Plant is hatching plans to equip its cars with engines of its own production. Work is underway to create a line of motors of various characteristics. And while at MAZ-6440 power units of the Yaroslavl engine plant are being installed. The question of the use of the engine "Mercedes" 457-series.

Unification

The new MAZ-6440 is assembled on a frame with spars. Heavy engine rests on four legs with rubber soles. Many sites are borrowed from beskapotnyh analogues, since the development and production of original parts are too expensive, and the release of MAZ-6440 is designed as a low-cost and must fit into estimates that do not exceed a certain average level. Completely switched to a new model front suspension, both rear axle axles with lockable differentials, braking system. The steering was developed anew and equipped with a hydraulic booster.

The tractor is equipped with ergonomic seats of high comfort, air conditioning, climate control, digital tachograph, electric top hatch, stability control system, refrigerator. The driver's seat is surrounded by the dashboard, the steering column is adjustable in height and inclination in the longitudinal plane. The car is not inferior in terms of comfort to foreign counterparts. In many ways, Belarusian tractors start to outpace the cars of American and European production.

Additional devices

• Cruise control - a kind of autopilot, regulating the movement of the tractor when the load increases (for example, climbing a mountain); The machine adds engine speed or reduces engine thrust on the descent;
• Electric lift mechanism of the hatch of the cabin, controlled from the dashboard with a special two-position button;
• Digital tachograph - a special device directly connected with the speedometer and fixing the distance traveled by the car.
• Installation climatic, automated, with electric drive on four flaps;
• Rear-view mirrors, controlled, electric and heated;
• Protective screens of headlamps made of carbon fiber;
• The system of traffic stability - an indispensable assistant driver, monitoring the stability of traffic;
• DVD-player of the system "quadro" with a five-seat changer;
• Illumination on the steps of the gangway;
• Refrigerator with a capacity of 40 liters;
• Sleeping places.

MAZ-6440: price

In 2011, when the serial production of a new tractor was launched, the managers of the Minsk Automobile Plant announced the prices for the car, but not in figures, but in a conditional measurement. It was announced that MAZ-6440 will cost 30% less than foreign analogues of this class. However, even with such an impressive discount, the tractor cost was about three million rubles, while conventional, non-truck MAZ trucks cost almost half as much.

Model 6440: reviews

To date, not many new tractors have been produced. The parameters of the machine require refinements, the design contains many modern technical solutions that have not yet been perfected, but in the future promise to justify the calculations of engineers.

And still, today drivers receive feedback, mostly positive. Truckers note a high level of comfort, good noise insulation and stability on the course of a heavy road train.
