The invention discloses a multifunctional all-
terrain special vehicle. The multifunctional all-
terrain special vehicle comprises a vehicle body, wheel assemblies, power driving devices, and transmission devices, wherein the wheel assemblies are mounted on the two sides of the vehicle body; power is provided by the power driving devices, and is transmitted to the wheel assemblies by the transmission devices; each of the wheel assemblies comprises a wheel shaft and two hubs; two ends of each of the wheel shafts are mounted at the top ends of two cantilevers through bearings; the bottom ends of the two cantilevers are connected with
cantilever driving devices mounted in the vehicle body, and the cantilevers are driven to swing up and down by the
cantilever driving devices; an outer ring of each of the two hubs adopts a
spiral line structure and sleeves the corresponding wheel shaft, besides, an outer edge of each of the outer rings is designed into a
cutting edge shape, and an inner ring of each of the hubs is designed into an embedded blade. The multifunctional all-
terrain special vehicle disclosed by the invention can be applied to the fields of military wars,
emergency rescue and disaster relief, polar investigation, civilian driving and the like, has the functions of enabling the height of a
chassis to be changed, enabling the distance between the wheel shafts to be changed, climbing hills, surmounting obstacles, travelling in water and on land and the like, and can be used for performing detection and operation in places with complex terrains and extreme environments, such as rock and soil, desert, ice surfaces, snowfields, swamps, and
deep water.
