general description
We study in more detail MAZ-6422. His cabin has significant differences from its predecessors. Changes affected the grille and the shape of the headlights. Also, the car lost the usual rounded shapes that were popular in the 1960s. Engineers also did not ignore the windshield, which they began to perform panoramic with an average stand. The large bumper, designed to protect against collisions, was excluded. He was not replaced by a special element equipped with the main headlight unit. The roof of the tractor 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 performance of the car's dynamics, and therefore this design did not go into mass production.
The dream of a trucker
MAZ-6422 is the car that really became very popular with drivers traveling long distances. The following factors served this:
- High degree of safety and convenience of the steering wheel.
- The seats are equipped with a spring suspension for increased comfort.
- The bridges of the machine after heat treatment have become stronger and more durable.
- The presence of two berths allowed a crew of two to travel continuously for hundreds of kilometers.
- The car turned out to be very maneuverable and obedient thanks to an eight-speed gearbox and a multiplier.
Smooth running and reducing the dead weight of the car became possible due to the use of small-leaf springs with a variable cross-section. In addition, these details allowed the truck to reach the international level, since this decision of the designers was appreciated abroad. A patent for this development was acquired by some Canadian companies, and even a whole factory was built to produce such springs.
A distinctive feature of the tractor is also electrical equipment, which at the time of production of the first models was advanced. These new items were:
- Cassette player.
- Tachograph.
- Pressure sensor in the brake system.
In conclusion, it should be noted that the MAZ-6422 was a real breakthrough in the domestic automotive industry and was able to completely reverse the traditional opinion of Soviet tractors.
