FIELD: transportation.
SUBSTANCE: invention relates to vehicles for movement onto surfaces of different media, in particular, to their chassis, which are characterized by arrangement of power plants and transmissions to drive simultaneously the front and the rear wheels. Chassis of a snow and swamp-going vehicle comprises a power plant with a transmission, a suspension of wheel axles equipped with superlow-pressure tires, which are fixed on bearing elements. Power plant is shifted from the central axle to the front one by distance A equal to (0.7…1.3)Dt, herewith distance B between the front and the central axles makes (1.5…1.9)Dt, distance C between the central and the rear axles is (1.07…1.5)Dt, where Dt is the outer diameter of the tire at rated inner pressure.
EFFECT: provided is better traction and dynamic characteristics of the snow and swamp-going vehicle chassis.
