MAZ » 7922

MAZ 7922 16x16 chassis was created based on the Model 7917 by replacing middle non-driven axle with driven 2-axle boogie. It was intended to be a chassis for the future missile complex 'Topol-M'. Development started in 1987 and the prototype was finished by 1990. Three front and three rear axles were driveable. The welded frame, tires, independent hydro-air suspension and two fiberglass cabins were saved from the Model 7917. Ground clearance — 475 mm, turning radius — 18.5 meters. Top speed — 40 kph.

The Model 7922 was fitted with a new turbocharged YAMZ 8401 V12 diesel with a capacity of 25.9 liters and power of 780 hp. It was connected with the old 4-speed gearbox. Curb weight — 39 tonnes. Range — 400 km. After the factory tests, MAZ 7922 turned out to be unnecessary. But in 1995 it was converted to the future mass-production MAZ 79221 chassis.
