Ship-shaped amphibious car

Abstract

The invention discloses a ship-shaped amphibious car. The ship-shaped amphibious car comprises four car wheel devices (14), hollow shaft devices (5) and four sets of worm wheel devices (39), wherein the four car wheel devices (14) are installed on four cylindrical-surface step hollow shaft rotating chassis devices (4) correspondingly; the first ends of the hollow shaft devices (5) are connected with a ship-shaped car body (1) through hinges, and the second ends of the hollow shaft devices (5) are fixedly connected with the four cylindrical-surface step hollow shaft rotating chassis devices (4); and the four sets of worm wheel devices (39) are installed on the first ends, inside the car, of the four hollow shaft devices (5) correspondingly, and rotating and stroke positioning of the four cylindrical-surface step hollow shaft rotating chassis devices (4) are driven by four sets of worm devices and the four sets of worm wheel devices (39). During switching of amphibious modes, when the four cylindrical-surface step hollow shaft rotating chassis devices (4) are all rotated by 180 degrees and switched into the water mode, the four car wheel devices (14) are rotated to the position above the ship bottom, and four stream-line surfaces (45) are rotated to the flat-bottom ship bottom (2) to take part in stream-line ship-shaped car body simulation so that the sailing resistance can be reduced.

Description

technical field [0001] The invention relates to an amphibious vehicle capable of navigating on water and traveling on land. Background technique [0002] When the amphibious vehicle sails on the water, the eddy currents formed by the wheels or tracks in the water generate greater resistance, which limits the further improvement of the navigation speed. At present, there are three main ways to increase the navigation speed of the amphibious vehicle: the first is to shrink the wheel device upwards Reduce the eddy current resistance generated by the wheels, but after the wheels are lifted, there will be depressions at the wheel arch cutouts. It is easy to be damaged when driving on land, and the failure rate is high; the second method is to design a ship bottom without a cover plate to close the wheel arch cutout after the wheel device is retracted upwards. The lowest point of the wheel arch cutout is above the bottom of the ship. When gliding at high speed, the wheel arch cut...

Problems solved by technology

A vehicle that replaces amphibious vehicles is the hovercraft. The advantages of the hovercraft are high speed and can land on complex terrain. The disadvantages are large volume, poor protection ability, high energy consumption, short voyage, loud noise during navigation, and exposed propellers. Large radar reflection area is not conducive to stealth, poor stability, poor performance in complex sea conditions, high manufacturing cost and high use cost, so hovercraft is not an ideal landing combat tool
