ABSTRACT:
A two-level sea-land creeping vehicle formed by three main parts: a frustoconical bow portion which is movable independently but connected to the central part or compartment in the form of a drop of water, which is flat in the lower part and which is fixed with respect to the rear part which comprises the drive and steering assembly, as well as the breathing and safety zone.
The vehicle is displaced on land by means of two rollers disposed in the lower region and by the drive of the motor, and it is likewise displaced on the surface of water due to its buoyancy and it is also displaced in a condition of dynamic immersion by the drive of the motor linked to positioning of the bow portion and hydroplanes; the air required is picked up from the surface by means of an appropriate telescopic arrangement and it has the particularity of not being hermetically sealed in the immersed condition. It is totally safe since it rises automatically to the surface when the motor stops.
