MAZ-6422 - an exclusive car from the Minsk Automobile Plant

Minsk Automobile Plant regularly encourages its customers with high-quality and reliable truck tractors. One of these trucks, which was created for transportation between cities and countries, is MAZ-6422. About him and will be discussed in our article.

Production options

From the conveyor this car descends in the following versions:

• MAZ-6422 is a basic type equipped with a diesel power plant. At this point in time is no longer produced.
• MAZ-64224 is a machine equipped with an engine with a capacity of 425 liters. from.
• MAZ-64221 - truck, which has a motor produced by the Yaroslavl Motor Plant.

general description

We will study in more detail MAZ-6422. His cabin has significant differences from its predecessors. Changes affected the radiator grille and the shape of the headlights. Also, the car lost its usual round shapes, which were popular in the 1960s. Do not ignore the engineers and windshield, which began to perform panoramic with an average rack. A large bumper, designed to protect against collisions, was excluded. He did not change a special element equipped with the main headlight unit. The roof of the tractor unit is crowned with an improved spoiler.

MAZ-6422 received a comfortable cabin with a very comfortable, adjustable driver's seat.

The front wings of the truck got a rectangular shape, but this technical solution somewhat worsened the dynamics of the machine, and therefore this design did not go into mass production.

The dream of a long-distance driver

MAZ-6422 is the car that really became very popular with the drivers who make long-distance trips. This was served by the following factors:

• High degree of safety and comfort of the steering wheel.
• The armchairs are equipped with a spring suspension for increased comfort.
• The bridges of the machine after the heat treatment became stronger and more durable.
• The presence of two berths allowed the crew of two people to pass continuously not one hundred kilometers.
• The car was very maneuverable and obedient thanks to the eight-speed gearbox and demultiplier.

Smooth running and reducing the weight of the car became possible due to the use of small leaf springs with variable cross-section. In addition, these details allowed the truck to enter the international level, as this design decision was appreciated abroad. A patent for this development was acquired by some Canadian firms, and even a whole plant was built to produce such springs.

A distinctive feature of the tractor is also the electrical equipment, which at the time of production of the first models was advanced. Such novelties were:

• Radio tape recorder.
• Tachograph.
• The pressure sensor in the braking system.

In conclusion, it should be noted that MAZ-6422 was a real breakthrough in the domestic automotive industry and was able to reverse the traditional view of Soviet tractors.
