General Description
Let's study the MAZ-6422 in more detail. Its cabin has significant differences from its predecessors. The changes affected the grille and the shape of the headlights. Also, the car lost the familiar rounded shapes that were popular in the 1960s. Engineers did not ignore the windshield, which began to be made panoramic with an average rack. A 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 topped with an improved spoiler.
MAZ-6422 received a comfortable cab with a very comfortable, adjustable driver's seat.
The front fenders of the truck received a rectangular shape, but this technical solution somewhat worsened the dynamics of the car, and therefore this design isdid not enter series production.
True driver's dream
MAZ-6422 is the car that has really become very popular with drivers traveling long distances. This was due to the following factors:
- High degree of safety and steering wheel comfort.
- Seats feature spring suspension for added comfort.
- The bridges of the machine are stronger and more durable after heat treatment.
- The presence of two berths allowed the crew of two people to drive continuously more than one hundred kilometers.
- The car turned out to be very maneuverable and obedient thanks to the eight-speed gearbox and demultiplier.
Smooth running and reduced dead weight of the vehicle are made possible by the use of small-leaf springs with variable 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 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 the production of the first models was advanced. These novelties were:
- Radio.
- Tachograph.
- Brake pressure sensor.
In conclusion, it would be worth noting that the MAZ-6422 became a real breakthrough in the domestic automotive industry and was able to completely overturn the traditional opinion aboutSoviet tractors.
