Abstract
An amphibious vehicle comprising: a chassis (10), which has a hull-like structure and comprises supporting wheels (11) and driving wheels (13-14) for tracks (12) of the rubber-clad type, a fore buoyancy reserve (21) and an aft buoyancy reserve (22) which are obtained by means of a corresponding fore element (21') and aft element (22') which are permanently applied by means of watertight welds (CS) to the chassis. A power plant (MP) comprises an internal-combustion engine and two hydraulic pumps (41'-41') which, by virtue of corresponding delivery circuits (42'-42'), feed first hydraulic motors (44'-44') for simultaneous or selective driving of tracks for propulsion and steering on land and second hydraulic motors (45'-45') for simultaneous or selective rotation of hydrodynamic propulsion and steering propellers.
